we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples 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 will be blocked by cement slurry during construction. At this time 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. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.San Pedro,The inner core of the grouting pipe is rigid, which can ensure that it will not be crushed under the concrete pressure. The non-woven filter cloth layer outside the framework only allows water and grouting fluid to pass through, and other materials such as cement slurry in concrete are blocked outside the grouting pipe to fully ensure the smooth use of the whole section of the grouting pipe. The flexibility of the product is very high, and it is easy to place at the corners without cutting and connecting. When grouting in the grouting pipe under pressure, the grouting can keep filling the whole pipe evenly. The system allows grouting at relatively low pressure. The installation of grouting pipes will not affect the characteristics of the building itself. The installation or grouting process will not harm the concrete. Permanent sealing can be ensured after grouting. If there is no leakage, grouting can be omitted. The key construction process flow of grouting pipe installation is as follows: table formwork processing, installation - grouting pipe processing - spring reinforcement framework, mesh binding - grouting pipe and installation of embedded reserved side formwork installation - process acceptance - concrete pouring - concrete curing - m data thickness to ensure the integrity of the table formwork, the steel plate joint weld shall be uniform. The grouting pipe is specially used as a channel for the depth detection of pile foundation and for structural stress calculation. The grouting pipe is a small pipe, but this small pipe meets the standard sensitivity of sound reception. As long as there is a small sound it can measure it and accurately reflect the data on the computer or sound receiver. During the concrete pouring of cast-in-place pile, a channel that allows the ultrasonic probe to be normally placed at the pile bottom is reserved which is not considered in the structural stress calculation.San Pedro, Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, screw connection, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and the outer pipe between the two convex grooves is deeply immersed into the inner pipe and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.However, not all grouting pipe products can achieve this effect. Some inferior grouting pipe products not only fail to achieve the expected effect in use, but also have problems such as low grouting efficiency, pipe burst and pipe bending, which seriously affect the grouting effect of the grouting pipe and the progress of the whole project. The quality of grouting effect comes from the selection of high-quality grouting pipe products. Shengpeng grouting pipe is a good choice for you to choose grouting pipe products because of its high strength, awesome, simple connection and high cost performance! Grouting pipe the grouting pipe is a kind of geosynthetic material formed by ultrasonic welding which is composed of a steel plastic composite reinforced belt (built-in high-strength carbon spring steel wire (stress material) and wrapped with polyethylene resin (protective material) and arranged at right angles to the plane longitude and latitude. It is a comprehensive product of existing rigid reinforcement (flat steel strip, ribbed steel strip, galvanized steel strip, reinforced concrete strip, etc.) and flexible reinforcement (polypropylene strip, warp knitted grouting pipe, etc.). Because of its high tensile strength, low elongation (≤ %), small creep, and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, restrict the lateral displacement of the soil, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation and improve the overall performance of the foundation; It can be widely used in road engineering, railway engineering, retaining structure, dam engineering, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking. The cooperation Specification between the saddle profile on the horseshoe of the grouting pipe and the core is too low. When the outer mold and the horseshoe surface are fitted together, the gap is larger than the thickness of the pipe wall, that is, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.

General treatment method: first, yze what causes the pipe blockage. For the pipe blockage of hard objects, you can poke with steel bars according to the depth, or bind a slightly thicker steel bar with steel wire rope. For the pipe blockage of soft objects,San PedroSmall catheter, you can use the air compressor pipe to open the air compressor for blowing. Be sure to note that the water in the pipe may rush up like a fountain to pour water all over you! If it is slurry leakage and pipe plugging, there is no way to open it. We can only communicate with the testing personnel to change a testing method, such as low strain and core drilling method! Other uses of the grouting pipe: in addition to being used as a detection channel and replacing part of the reinforcement section, the grouting pipe can also be used as a pipe for grouting at the bottom of the pile. Experiments have proved that the bearing capacity of the cast-in-place pile treated with the grouting at the bottom of the pile can be greatly improved. At the same time, it is necessary to take measures to punch through the pipe at the defective part to be grouted. Grouting pipe is specialized in the production of grouting pipe (ultrasonic detection pipe) for bridge pile foundation inspection. The product conforms to the industrial standard steel thin-walled grouting pipe for concrete cast-in-place pile and its use requirements (JT / T -, which was tried out by the Ministry of communications of the people&#;s Republic of China on April , It can not only meet the requirements of the standard,San PedroLeading small conduit production,San Pedro48lead small conduit, but also greatly improve each index, and each loop is m according to the paper requirements. Put the outer layer of fabric into the blue horn interface to try the tensile property and confirm that it has been inserted to the end. The other end of the horn is sleeved with a PVC reinforced grouting pipe. It pipes shall be arranged according to the direction of construction joints, and installed mm away from the back water surface. Note that the green it pipe itself cannot be exposed to the concrete to be poured, and ensure that the PVC pipe is exposed outside the concrete for grouting in the future. Cement nail fixing clips or iron wires shall be used for fixing every other distance, and the distance between two fixing points shall be ≤ cm. The ends of it pipes of two adjacent circuits must overlap by at least cm. The exposed PVC pipe is installed in the grouting interface box to facilitate grouting in the future.Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.Quality improvement,Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.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.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, we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, 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 will be blocked by cement slurry during construction. At this time, 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, 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.

Can the stretching speed of grouting pipe be defined?Bidding, Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material, high-strength alkali free glass fiber through a certain warp knitting process, and fiber filament coated on both sides.When installing the Hainan grouting pipe, carefully check the embedded reinforcement in the groove before the joint is lowered. If cracks or breaks are found, the position is improper or the gap is too large, remedial measures must be taken. Classification of grouting pipe grouting pipe the grouting pipe is a plane mesh material of grouting pipe with certain flexibility. The main raw material is polyethylene grouting pipe. It is extruded into thin sheets by a grouting pipe extruder, and then punched with regular holes. Then it is made by directional stretching under the control of heating. It can be divided into unidirectional grouting pipe and bidirectional grouting pipe according to the different stretching modes when it is manufactured.San Pedro,At the same time, because the space in the grouting pipe restricts the lateral sliding and rolling of the soil particles inside, the relative displacement trend or relative displacement also occurs between this part of soil particles and adjacent soil particles, resulting in friction. This friction force is generally called 'bite force' or 'lateral force resistance'. The 'surface friction' and 'bite force' make the slip and roll of soil particles under the force of the upper limit line at the location of the grouting pipe, and limit the lateral displacement of soil in the whole plane of the grouting pipe. The grouting pipe plays an important role in the key points of settlement. Therefore it is reasonable to use the grouting pipe to treat the uneven settlement of fill excavation transition subgrade. This paper yzes the action mechanism of the grouting pipe according to its type and characteristics, introduces the construction technology and process in the construction of preventing the reflection crack of the road surface, and proposes a new technology of sprinkling a layer of filler in the grouting pipe network when paving the surface course. As a kind of road reinforcement material, grouting pipe is widely used in road maintenance engineering because of its advantages of simple, fast construction and low investment.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'. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.
