The grouting pipe shall be cut with a toothless saw (grinding wheel clamp). Cutting by electric or gas welding is easy to damage the surrounding surface and cause local heating at the end, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.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, stainless steel strip, reinforced concrete strip, etc.) and flexible reinforcement (polypropylene strip, plastic grouting pipe, 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.South Boston, Slump test shall be carried out for concrete entering the site. No less than groups of test pieces shall be made for the same batch of concrete with the same strength grade. One group is used for standard curing, and the other two groups are used for curing under the same conditions to determine demoulding and allowable lifting time.How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.After checking that the installed formwork is tight and seamless, clean the reserved groove, then pour concrete and vibrate it tightly. The concrete shall have at least the same strength as the structural concrete at this place, and the grouting pipe device in Hainan shall be kept clean when pouring concrete.Hamina, The length can be matched according to the construction requirements, without loss. 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.A short section of screw end rod is welded on both ends of a single prestressed thick steel bar, and then to the concrete components around the reserved hole crossing through the base plate.Let&#;s take a look at the prestressed machines and tools. The small editor of prestressed machines and tools reminds everyone that the screw end rod is made of cold drawn or heat-treated reinforcement, and the thread is fine teeth. The welding between the end rod and the prestressed reinforcement should be carried out before the cold drawing of the prestressed reinforcement. This grouting pipe can be used at the tensioning end and the fixed end. A general jack is used for tensioning, and the jack pull rod (with internal thread at the end) is tightened on the thread of the screw end rod for tensioning. After tensioning, tighten the nut and anchor the rebar. The advantages of this grouting pipe are relatively simple, and when the jack returns oil after the grouting pipe, the prestressed reinforcement basically does not slide. If necessary, facilitate re tensioning. The disadvantage is that the accuracy of the length of prestressed reinforcement is high, and it cannot be too long or too short, otherwise the thread length is not enough.

It is safe and does not need to be welded on site. During measurement, you will know how to solve them The first point is that if the joint we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, 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, 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.Inspection environment,The grouting pipe can be divided into unconstrained grouting pipe and constrained grouting pipe according to whether it can absorb the pressure thrust (blind plate force) generated by the medium pressure in the pipe; According to the displacement type of the grouting pipe, 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, welding slag is not allowed to splash onto the surface of grouting pipe and suffer other mechanical damage; All movable components of the grouting pipe shall not be jammed by external components or restrict the normal operation of its movable parts. Most of the failure of the grouting pipe is caused by the external environment corrosion. Therefore, 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 the bamboo wood grouting pipe has been eliminated by the market. Grouting pipe has become the mainstream form of grouting pipe and is more widely used in construction.Plastic pipe plastic pipe has a low acoustic impedance, which is used as a grouting pipe and has a large acoustic transmission rate. It can usually be used for smaller cast-in-place piles. It should be cautious when used in large-scale cast-in-place piles - because large-diameter piles need to be poured with a large amount of concrete, and the hydration heat of cement is not easy to dissipate. In view of the great difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after concrete solidification, It may be separated from the concrete locally to cause air or water crevices, which is easy to cause misjudgment. 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.

Can the piston rod of the grouting pipe be protected to avoid being bruised and accelerating leakage?Honest management,Causes of wrinkling: the blanking specification of pipe joint is too long.[] It is believed that it is undoubtedly one of the research directions of new grouting materials coordinated with the sustainable development of the times to develop high-performance and green grouting materials by effectively using large quantities of industrial wastes instead of pure cement clinker in China.The stability of the grouting pipe is one of the important factors to control the stability of the whole foundation pit. Its erection must be accurate and in place, and prestress must be applied in strict accordance with the design requirements. In particular, every link of the installation must be carefully operated. At the same time, the steel purlin must also ensure its stability, strength and deformation requirements during the production and installation process. In addition, During the whole construction process from foundation pit grouting pipe erection to removal, the grouting pipe must be strictly monitored to ensure its stability. How to improve the bearing capacity of piles with grouting pipes in bored piles, during the drilling process of large-diameter cast-in-place piles, the soil layer around the piles will become loose due to the agitation of the turning heads. In addition, the water immersion makes the soil layer that has started to loosen more loose. This problem can be effectively solved by grouting with grouting pipes. How to improve the bearing capacity of piles when grouting with grouting pipes?South Boston, The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.In China, the types of grouting pipes are relatively complete now, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.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,South BostonCustomized leading small catheter, 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, convenient and labor-saving. Some units do not know it, so its design has certain limitations, 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,South BostonLeading small catheter, so they will be in a passive position. Therefore, we hope that some industries, such as machinery manufacturing, automobile and motorcycle, transportation equipment, box manufacturing such as tool boxes, medical treatment, fitness, kitchen cabinets, etc, If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you advice
