In limestone area the punching is not good, the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means, and even can not be detected. Therefore, when the grouting pipe is found blocked after the foundation pile is poured and before the inspection, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement, flushing and pigging with high-pressure water, and using a drill with a small drill to clean the hole.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 ChinaHorsens,At present, Wuhan University of technology has completely replaced cement clinker with ground industrial waste slag (fly ash slag and steel slag) and successfully prepared a new type of two liquid grouting material with different gel time ( ~ s), high consolidation strength (~ MPa) and stone rate of by using water glass to stimulate industrial waste slag, without loss.Schweichard, 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,HorsensPrice of advanced small conduit, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators, etc.The existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.In the construction of some grouting pipes, after the completion of the construction of the project because some construction personnel did not take protective measures after the completion of the grouting pipes, the project was damaged due to some external factors. In order to help users effectively improve the construction quality of the grouting pipes, the following article introduces the protective measures that should be taken after the completion of the construction of the waterproof layer of the grouting pipes. For various engineering designs,HorsensSupport small conduit, waterproof and water stop shall be carried out throughout the whole process of grouting pipe until the backfilling soil is completed.

It has good air tightness, low gas permeability, strong sealing and no leakage. The installation is simple, fast and firm. At least one part of the grouting conduit buried in the concrete shall be firmly bound with the structural reinforcement; The length of the grouting duct leading out of the concrete shall not be less than mm; The leading end of the grouting conduit shall be set at a convenient and accessible position. No part of the grouting conduit shall be flattened or bent to avoid affecting the flow of grout. The opening end of the conduit shall be temporarily blocked to prevent foreign matters from entering. The damaged part of the grouting pipe shall be cut off, and the grouting pipe with the installed grouting pipe shall be re set at the cut-off part, and shall be overlapped with the original grouting pipe at both ends.When binding or welding reinforcement near the grouting pipe, temporary shielding measures shall be taken to protect the grouting pipe. The calculation of the reserved expansion amount of the grouting pipe and the bridge expansion joint changes all the year round. With the change of temperature and the change of vehicle live load, the bridge will shrink and deform. The grouting pipe and the bridge expansion joint play a major role at this time. The expansion amount of the grouting pipe and the expansion joint must be calculated accurately. The installation and construction of the grouting pipe and the expansion joint need to ensure the quality. We should select the model and type of grouting pipe and bridge expansion joint, and determine the installation time, installation season and temperature of grouting pipe and expansion joint. Calculate the large and small preload of grouting pipe and expansion joint.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, 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, 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.Discount,In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, 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, 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, and some occur on the outer arc surface. 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. Sometimes the grouting pipe is overlaid on the two sides of the horseshoe surface. Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of 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, 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.Design brand,In the construction of some grouting pipes, after the completion of the construction of the project, because some construction personnel did not take protective measures after the completion of the grouting pipes, the project was damaged due to some external factors. In order to help users effectively improve the construction quality of the grouting pipes, the following article introduces the protective measures that should be taken after the completion of the construction of the waterproof layer of the grouting pipes. For various engineering designs, waterproof and water stop shall be carried out throughout the whole process of grouting pipe until the backfilling soil is completed. advantages: Simple installation, complete set; The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (it is recommended that the longest grouting outlet length should not exceed m); No special installation equipment is required; four Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material,HorsensGrouting pipe grouting, high-strength alkali free glass fiber through a certain warp knitting process, and fiber filament coated on both sides.Horsens,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.There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe. It has good air tightness, low gas permeability, strong sealing and no leakage.
