The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.
Flexibility: it is convenient to place at the corner without cutting and connecting.
Finance Department. 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.
This seems to test what I learned in junior high school. The formula for calculating the weight per linear meter of a cylinder I learned at that time is now used. However, it may be more troublesome to calculate according to that formula. It is necessary to calculate the weight per linear meter of the outer cylinder with the formula, and then subtract the weight per linear meter of the inner space. I have a headache when I think about it! With less gossip, I'd better provide you with a method to correctly calculate the weight of the grouting pipe per linear meter!
Construction Engineering Investigate the characteristics of surrounding rock, clarify the purpose of grouting, cement grouting has been the main grouting method in engineering. However, ordinary cement can only be filled with sand gravel or pores with a diameter greater than 0.2 ~ 0.3mm due to its coarse particles. Therefore, improving the fineness of cement particles has become the main way to improve the groutability of cement slurry. Some countries have developed a kind of ultra-fine cement, which can pour fine sand with permeability coefficient of 10-3 ~ 10-4cm / s and micro cracks in rocks. It is a promising granular grouting material. Propionate is a kind of water-soluble polymer chemical slurry, whose viscosity is close to that of water. It is widely used in anti-seepage grouting and dynamic water plugging of fine rock cracks and medium fine sand layers. However, this kind of pulp material is toxic and pollutes the air and groundwater, AC400 slurry was developed in the United States, and in 1982, ac-ms slurry was developed in China. The toxicity of this kind of slurry is very small (only 1% of the toxicity of propionate). It is an ideal anti-seepage slurry. The non alkaline silicate slurry developed in Japan has no alkaline pollution to groundwater, low viscosity, high gel strength, and to improve its physical and mechanical properties through replacement, filling, extrusion and other methods to make ceramic bodies suitable for processing.Make it into a certain shape, size and specification. Seepage prevention Water plugging 3
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 1949 and in the early 1950s, 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.
Chemical grouting chemical grouting materials are mainly used in water glass and organic polymer grouting materials.
Lesbridge.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.
The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed. With the innovation and application development of industry technology, I have always been at the forefront of the industry. Lianye people have always been market-oriented, committed to serving the bridge construction industry,Lesbridge22hollow composite anchor manufacturer, railway and highway industries, and have successively developed a series of excellent acoustic pipe manufacturers serving the construction industry, such as grouting pipe, pump pipe and pile foundation acoustic pipe.
The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed. Product advantages: Simple installation, complete set. No special installation equipment is required, and the cut-off length can be prepared on the construction site according to the actual requirements of the joint (it is recommended that the longest grouting outlet length should not exceed 6m). The grouting time can be arbitrarily selected.
