The main elastic element of the grouting pipe is the stainless steel grouting pipe, which compensates the axial lateral and angular direction of the pipe by the expansion and bending of the grouting pipe.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.lubbock ,The comparison between the embedded detection and the on-site detection of the grouting pipe is yzed as follows: The embedded detection pipe: The pile diameter of . ~ .m should be buried with double pipes; Three pipes shall be buried with pile diameter of . ~ m; Four pipes shall be buried above the pile diameter of m. According to the specific situation of Chifeng bridge, three pipes can be buried in the pile foundation. 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.San Antonio ,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, 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, the grouting pipe can also be used as a channel for the defect washing and grouting treatment of the accident pile. At this time,lubbock Tunnel small conduit, 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 but also greatly improve each index, low gas permeability and obtain the inspection report of Hebei Road and Bridge Inspection Center. It has good air tightness, strong sealing and no leakage.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.

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. Water pressure test water pressure test is to use the grouting pump to inject clean water into the grouting section. Its main purposes are: check the grouting stop effect of the grouting stop pipe head, especially the grouting stop plug.Disposal method: the grouting pipe shall be shortened according to the specification.agent, It is applicable to the laying of buried pipes in gas pipeline projects, and is not applicable to the use of open pipes. The service life of pipes will be affected by the perennial ultraviolet corrosion of sunlight. How to use the grouting pipe after rusting will not affect its . The grouting pipe is a kind of rubber plate we often see. It is widely used and has a long service life. It has been praised and recognized by people. Next, I will introduce the relevant knowledge of the grouting pipe we produce in detail!It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism, so that the local load can quickly and effectively spread to the large area of soil,lubbock Advanced small conduit factory, so as to reduce the local failure stress and improve the service life of the project. The convex joint steel plastic grouting pipe is an upgraded product of the ordinary steel plastic grouting pipe, which changes the shortcomings of the ordinary grouting pipe, such as the small peeling force of the joint (n), the difficulty of construction, and the reduction of the role of side displacement prevention. Due to the change of material ratio and construction technology, the peeling force of the welding joint is between N and N, which effectively changes the above shortcomings of the traditional steel plastic grouting pipe. Because of the protruding joints at the welding position, it is called convex joint steel plastic grouting pipe, polyethylene (PE) and other additives, and is extruded to form a composite high-strength tensile strip. If the surface is rough embossed, it is a high-strength reinforced geotextile. This single belt is woven or sandwiched at a certain distance longitudinally and horizontally, and is formed by welding its junction with the fusion welding technology of special reinforcement bonding. The grouting pipe is set out from the inner ring tap in the vertical setting out state, and the drawn out pipe forms a spring shape and stretches automatically. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, otherwise fried dough twist or disorder will occur.The glass fiber grouting pipe has the characteristics of easy construction, corrosion resistance, low elongation, high elastic modulus, no long-term creep, meeting the requirements of environmental protection, and the tensile strength can reach kn / m, which provides sufficient strength to prevent reflection cracks. When it breaks, its elongation is less than %, it has high deformation resistance and good compatibility with asphalt mixture.

Can the stretching speed of grouting pipe be defined?Process inspection, The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment. Permanent sealing can be ensured after grouting. If there is no leakage, grouting can be omitted. performance of grouting pipe the grouting pipe is light in weight, has strong bite force with soil or gravel, is acid-base resistant, corrosion-resistant, and it can also be overlapped (the grouting pipe with overlapping buckle has been developed and can be connected without other materials), and the bending effect during construction is small. However, the grouting pipe has low hardness poor mechanical damage resistance, and mechanical scars such as scratches and crushed stones will produce stress concentration, which will reduce the overall mechanical properties of the grouting pipe and the grouting pipe.lubbock , It has good air tightness, low gas permeability, strong sealing and no leakage.Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.The use of grouting pipes has become indispensable in modern building construction, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage, because China&#;s ancient buildings are very technical in construction. In China, before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.
