It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found, it should be repaired. If necessary, the steel beam spacing of maolehan grouting pipe shall also be adjusted according to the ambient temperature during installation. XF type grouting pipe device shall be slowly put into the groove, so that the center line of the joint coincides with the center line of the actual reserved joint, and the deviation shall not exceed mm. Meanwhile, the inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of its steel beam shall be adjusted according to the longitudinal, transverse slope and elevation to be ~ mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation. It is a thermoplastic material, which can be processed and formed many times providing convenience for hot melting and electrofusion connection of pipes.Akoyapa,Polymer chemical grouting method is applicable to reinforcement of sandy soil foundation, curtain grouting of dam foundation, water stop and leakage stoppage of underground engineering, reinforcement of muddy interlayer of dam foundation and fault fracture zone. There are many varieties of polymer chemical pulp materials, including epoxy resin, acrylamide (propionate), polyurethane (cyanogen), lignin, etc. Acrylamide and polyurethane are commonly used in chemical grouting of foundation. Acrylamide pulp is composed of main agent acrylamide and various admixtures. The viscosity of the slurry is close to water, and it has good groutability. After the slurry solidifies, the gel is impermeable, and has good durability and stability. This kind of slurry is widely used in seepage prevention grouting of fine rock cracks and medium fine sand layers and dynamic water leakage stoppage projects. This kind of pulp has certain toxicity and pollutes air and groundwater. The polyurethane slurry is mainly composed of polyisocyanate and polyether resin,AkoyapaCustomized leading small catheter, and then mixed with various admixtures. After the slurry is poured into the formation, it reacts with water to form polyurethane foam, which can strengthen the foundation and prevent seepage and leakage. Polyurethane slurry can be divided into water-soluble and non-water-soluble. The water-soluble polyurethane can be miscible with water and react with water to form an aqueous gel; Water insoluble polyurethane can only be miscible with organic solvents. Polyurethane slurry has low viscosity, good groutability, high stone strength, safety and reliability, no pollution to the environment, simple operation and high economic benefits.Answer: Yes, the elastic extension speed of the grouting pipe can be defined within a certain range in the design, but for a grouting pipe that has been designed, its elastic extension speed is certain.Solnock,Grouting pipe grouting pipe manufacturer clamp type grouting pipe grouting pipe price grouting pipe spot grouting pipe specification grouting pipe model grouting pipe raw material for grouting pipe grouting pipe is processed by welded pipe or spiral steel pipe, and grouting pipe processed by seamless steel pipe is generally rare in the market. The reasons are as follows: first, in terms of price, generally, the cost of grouting pipes made by welding is relatively low, in terms of processing technology, welded pipes are relatively easy to process and the equipment required is relatively simple. If spiral steel pipes and seamless steel pipes are processed, it is also commonly called clamp down grouting pipe. The clamp grouting pipe has the following characteristics: the connection of the grouting pipe is simple, as long as the hydraulic clamp is required for connection. The grouting pipe has joints at both ends of the clamp type grouting pipe, which avoids the possibility of loosening and has good seismic resistance. Several common failures in the installation of grouting pipes always have many problems when using grouting pipes for work. In order to enable everyone to provide production to the factory normally, you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed, it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes. After the two pipes are connected by using the deformation of the grouting pipe, the kneading part of the joint is large at both ends and small in the center, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper, stable and excellent s in terms of tensile pull-out and torque resistance, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators, etc.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole, the Jiangsu acoustic tube can be used normally in the process of application and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device, the resistance of Jiangsu acoustic pipe will appear in the process of application, resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application, because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, it is necessary to pay attention to the method of the device in the process of the device, so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period, and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, and there is a concave appearance on the adjacent side. This kind of wrinkle is mostly in the shape of sharp ridges, some of which are straight to the nozzle, and often occur symmetrically at both ends of the center line, in the shape of 'eight'. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, it can be divided into axial grouting pipe, transverse grouting pipe, angular grouting pipe and pressure balance grouting pipe. The grouting pipe cannot bear load and should be hoisted separately; In addition to the pre deformation required by the design for pre stretching or cold tightening, it is forbidden to adjust the installation deviation of the pipeline by deforming the grouting pipe; During installation, in the structural design of the grouting pipe, the contact between the external corrosion medium and the grouting pipe can be considered. For example, for the external pressure axial grouting pipe, a packing sealing device can be added between the outlet end ring and the outlet pipe, which is equivalent to the sleeve grouting pipe. It can not only resist the invasion of external corrosive media, but also add a safety barrier to the grouting pipe. Even if the grouting pipe is damaged, the grouting pipe can also play a compensation role and avoid the failure of the grouting pipe. The use of grouting pipes has been indispensable in modern building construction. In the s, grouting pipes were popularized in China, but they were fastener grouting pipes. In the s, China began to develop advanced grouting pipes with multiple s. With the continuous development of China&#;s construction industry in modern times, the construction industry has become increasingly mature and perfect in China, and some construction sites have different requirements, so there are few in stock. In fact, they have different styles and different names. There are cross pair perforations and plum blossom holes. There are about holes in the whole pipe, which can be described as a hundred holes. One end of this pipe has plugs, sharp and round, depending on the customer&#;s requirements. The other end is welded with reinforcing bars from the pipe section to prevent the pipe section from tearing. This kind of pipe is called steel flower pipe. Steel flower pipe is generally used for high-speed maintenance grouting to protect mountains and prevent landslides. Holes are drilled on the steel flower pipe, which is more conducive to the penetration of cement mortar liquid into the rock and soil mass of the rock stratum and to the anchoring. In order to prevent the hole from being blocked by stones, sometimes the design requires reinforcement to protect the hole. After grouting the pipe orifice must be closed, so as not to let the grouting liquid flow out. The general classification of grouting pipe models can be divided into ordinary standard connection and pipe hoop connection according to their different connection methods.Answer: according to the length and diameter, the weight of common grouting pipe is . ~ .KG, and the weight can reach several kilograms.Application scope and development space of grouting pipe as a new term, grouting pipe has gradually appeared in some online newspapers and periodicals, and its practical scope has also developed from the support of some basic automobile boot and engine cover to the machinery manufacturing industry, used for the support of equipment accessories, vibration reduction of equipment, support of tool box cover, medical industry, fitness equipment and other fields. As its practicality is further recognized, its scope of application is becoming wider and wider. Some people in the industry asked: the application range of grouting pipe is becoming wider and wider. Does it have an impact on the original telescopic spring? In my personal opinion, it will not impact the original spring. Of course it will have a certain impact, because most of the grouting pipes are innovations in the product design of some enterprises. For example, the rear box of a tricycle was originally supported by an iron bar (which is still useful). Now, the grouting pipe is very light, convenient and labor-saving. Some units do not know it, so its design has certain limitations,AkoyapaSupport advance small conduit, However, enterprises must be innovative in order to be ahead of their peers. We have been making grouting pipes for many years. Experience tells us that many manufacturers are now trying our grouting pipes, and they have been officially used, with obvious effects. However, some enterprises do not know what the grouting pipes are let alone their s, we hope that some industries, such as machinery manufacturing,Akoyapamanufacturer of composite anchor rod, automobile and motorcycle, transportation equipment, box manufacturing such as tool boxes, medical treatment, kitchen cabinets, If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you advicetechnological innovationThey shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process, transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete. The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.When the pipe cannot be connected due to serious blockage, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe?

The grouting pipe is used as the pipe for grouting at the bottom of the pile. The test shows that the bearing capacity of the cast-in-place pile treated with the pile bottom grouting can be greatly improved At the same time, the grouting pipe can also be used as the pipe for the defect washing and grouting treatment of the accident pile. At this time, it is necessary to take measures to punch the pipe at the defect position where grouting is required. The classification of the grouting pipe can be divided into three categories according to the pipe materials: the advantages of steel pipe steel pipe are that it is easy to install, and it can be welded on the reinforcement frame by electric welding, which can replace part of the reinforcement section, and because of the large rigidity of the steel pipe After embedding, the parallelism and straightness can be basically maintained. At present, many large-diameter cast-in-place piles use steel as the grouting pipe. However, the price of steel pipe is relatively expensive: steel corrugated pipe steel corrugated pipe is a better grouting pipe material. It has the characteristics of thin pipe wall, less steel, impermeability, pressure resistance, high strength and good flexibility. It is usually used for post tensioning reserved holes in prestressed structures: when used as grouting pipe. It can be directly bound to the reinforcement framework soil, and the joint can be connected with a larger corrugated sleeve. Since the bellows is light, it is very convenient to operate but attention should be paid to keeping its axis straight during installation.Installation works,Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range. It has good impact resistance and high fracture elongation. Experience has proved that it can resist the impact of natural disasters such as earthquakes.In the engineering practice, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil, and the roller rolls after it. The effect is good, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, and forbid vehicles to swerve, brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between . Therefore, the relative displacement trend or relative displacement will occur between the narrow two which will then generate friction. This friction is generally called 'surface friction'.Akoyapa, The length can be matched according to the construction requirements, without loss.The small editor of prestressed machines and tools will lead you to understand the main connection methods between the drive device and the wellhead: the connection between the flange of the drive head of the electric oil pump and the parallel flange is the most widely used one at present. There is a flange at the lower part of the drive head, and the size matches the flange of the Christmas tree wellhead. It is a thermoplastic material, which can be processed and formed many times, providing convenience for hot melting and electrofusion connection of pipes.
