It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in China Low cost, fast time, no loss, free from climate and place constraints.Kanas,The construction steps of the three grouting methods are basically the same: the lower pipe grouting pipe grouting method and the flower pipe grouting method generally use the vibration method to place the grouting pipe into the soil at a predetermined depth. In the case of a large depth, the method of pre drilling a certain depth and then vibrating in can also be used. The drill pipe grouting method directly relies on the drilling method to place the grouting pipe (drill pipe) into the soil.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, and when the mold is finalized so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, 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, and some occur on the outer arc surface.Caldad da Rainha,When the grouting pipe is installed, the axis deviation shall be ≤ cm, and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile, in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied.Advantages: It is connected with special hydraulic tongs, does not require preparations outside the construction site, does not require any equipment, is convenient and fast ( times faster than the traditional welding method), is simple to fix the grouting pipe to the reinforcement cage,KanasGrouting small conduit, and is not affected by the bad weather.How heavy is a grouting pipe?

The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality but the excessive strength will be harmful to the quality of the upsetting head. Therefore, you should explain it in detail to the manufacturer in the order. 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 when you choose the upsetting head anchor, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.[] when the utility model is in use, the flange plate is used to fix the utility model and the flange plate of the underground grouting pipe, the bolt is rotated with a tool, the cutting blade is adjusted to a certain position by the screw on the bolt, and then fixed, and then the screw cap of the blade is rotated and tightened to make the cutting blade and the pulley contact the inner surface of the grouting pipe with a certain contact force, that is, neither loose nor tight. The cutting blade and the pulley are directly inserted into the concave groove of the rotating device through the slot, and the cutting rotating device is fastened and rotated by a wrench or a tooth wrench, and the pulley and the blade are driven to rotate by the rotation of the bolt, thereby rotating the casing. The pulley is located on the other side of the rotating device, corresponding to the blade. It is mainly used to reduce the friction between the rotating device and the casing wall, and fix the position of the blade in the casing, so as to prevent the blade on one side from shifting during cutting, failing to achieve the cutting purpose, or even damaging the blade. The fastening bolt is rotated by a wrench or tooth wrench, so as to drive the pulley and blade to rotate. The cutting rotating device cuts the casing. When the casing is cut to a certain depth, the blade nut is tightened again and the cutting continues until the casing wall is cut through. It has the characteristics of - times higher work efficiency than manual cutting and lower labor intensity of workers.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. Other uses of grouting pipe introduction the grouting pipe of pile foundation refers to the steel pipe that needs to be embedded when testing the quality of pile foundation. Generally, it is bound in the reinforcement cage and lowered into the hole together with the reinforcement cage before pouring concrete! There are many reasons for the grouting pipe to gamble on the pipe, most of which are due to the leakage of slurry caused by the pipe joint not being welded well during processing, and also due to the pipe mouth not being closed well and falling debris, the pipe is blocked! To put it bluntly, the pipe is blocked by sundries! The role of the grouting pipe is to inject clean water into the grouting pipe and put the transducer into the grouting pipe for testing when the integrity of the pile foundation is tested by ultrasonic wave. If the grouting pipe is blocked, the transducer can not be put in, or can not be placed at the bottom of the pile, so it is impossible to comprehensively test the whole pile and judge the quality of the pile foundation!Economic management,?The arrangement of the strain gauge shall be installed before the prestressing force is applied, and the bracket shall be fully cooled when the initial reading is measured; If the prestress has been applied, it must be noted in the report that the supporting axial force data reflects the change of the stress of the grouting pipe after the prestress is applied.Welding is strictly prohibited during use, because the strength of the welding point is much lower than that of the steel itself, and it is easy to cause broken wires at the welding point during tensioning. When the grouting pipe adopts circular reinforcement arrangement, its bending radius shall not be less than times of the diameter. The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality, but the excessive strength will be harmful to the quality of the upsetting head. Therefore, when you choose the upsetting head anchor, you should explain it in detail to the manufacturer in the order.

The research shows that the friction between the grouting pipe and the soil is also greatly related to the water content and compactness of the soil. The grouting pipe itself has a pattern, and is also a grid like integral geo reinforced material, so the friction between the grouting pipe and the medium is very large; The grouting pipe also has a great tensile strength, a large deformation modulus, and the reinforcement is stable and uniform, which can see good results in a short time. It can be seen from the experiment that the mesh reinforcement performance of the grouting pipe is better than the strip reinforcement material, which increases the stability of the project; The grouting pipe is especially suitable for the construction of high-speed highways, because the action force of the back and forth traffic on the soil is very great, and the grouting pipe can share the stress, increase the deformation modulus of the soil, effectively enhance the strength of the soil,However, 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. Steel pipe, plastic pipe or steel corrugated pipe should be used as acoustic detection pipe, and its inner diameter should be ~ mm. The connection of detection pipes shall be smooth transition, the nozzle shall be more than mm higher than the pile top, and the nozzle height of each detection pipe shall be the same. The lower end of the pipe shall be closed, and the upper end shall be covered. There shall be no foreign matters in the pipe and no damage to the pipe body.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,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,KanasSupport small conduit, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe. 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, 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. 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.
