Jixi acoustic testing tube grouting pipe (Xiaoguo 18733769276) spiral acoustic testing tube, Jixi acoustic testing tube grouting pipe acoustic testing tube, Jixi acoustic testing tube grouting pipe flange acoustic testing tube The testing tube manufacturing provider has established supporting Jixi acoustic testing tube grouting pipe spiral acoustic testing tube, Jixi acoustic testing tube grouting tube acoustic testing tube, Jixi acoustic testing tube grouting pipe acoustic testing tube product line, in the next few years In the construction industry, the annual compound growth rate of Jixi acoustic pipe grouting pipe spiral acoustic pipe, Jixi acoustic pipe grouting pipe acoustic pipe, Jixi acoustic pipe grouting pipe flange acoustic pipe market will break through, and it is expected that In the construction industry, Jixi acoustic pipe grouting pipe spiral acoustic pipe, Jixi acoustic pipe grouting pipe acoustic pipe, Jixi acoustic pipe grouting pipe flange type acoustic pipe should replace the traditional Jixi acoustic pipe grouting pipe. The pipe spiral type acoustic pipe, Jixi acoustic pipe grouting pipe acoustic pipe, Jixi acoustic pipe grouting pipe flange type acoustic pipe model has become the mainstream of the industry. Ganbang building materials Jixi acoustic pipe grouting pipe spiral acoustic pipe, Jixi acoustic pipe grouting pipe acoustic pipe, Jixi acoustic pipe grouting pipe flange acoustic pipe enterprise Jixi acoustic pipe grouting pipe spiral Type acoustic pipe, Jixi acoustic pipe grouting pipe acoustic pipe, Jixi acoustic pipe grouting pipe flange acoustic pipe migrate to foreign markets, create the first brand in China's construction industry, and establish the corporate image of a supermarket in the construction industry. By adopting the construction industry structure of Jixi spiral steel pipe, Jixi steel pipe grouting pipe, and Jixi steel pipe flange steel pipe, we have overcome the traditional internal deployment Jixi acoustic testing tube grouting pipe spiral acoustic testing tube, Jixi acoustic testing tube grouting pipe acoustic testing tube, Jixi acoustic testing tube grouting pipe flange type acoustic testing tube many problems, customers do not need to purchase, install and maintain by themselves By upgrading software or hardware, you can instantly solve the problem of Jixi acoustic pipe grouting pipe spiral acoustic pipe, Jixi acoustic pipe grouting pipe acoustic pipe, Jixi acoustic pipe grouting pipe flange acoustic pipe troubleshooting And installation, and can customize differentiated processing solutions according to different needs, companies can more flexibly deploy Jixi acoustic testing tube grouting pipe spiral acoustic testing tube, Jixi acoustic testing tube grouting pipe acoustic testing tube, Jixi acoustic testing tube injection Slurry pipe flange acoustic pipe application.
Currently, commonly used pipes include steel pipes, steel corrugated pipes, and plastic pipes. The advantage of the steel pipe is that it is easy to install. It can be welded to the steel frame by electric welding, which can replace part of the steel bar section. Moreover, because the steel pipe has a large stiffness, it can basically maintain its parallelism and straightness after installation. At present, many large-diameter cast-in-place piles are made of steel. Jixi acoustic tube grouting pipe. However, steel pipes are more expensive. Steel corrugated pipes are a better material for Jixi acoustic pipe grouting pipes. They have the characteristics of thin pipe walls, less steel, impermeability, pressure resistance, high strength, and good flexibility. They are usually used When the holes reserved by the post-tensioning method in the prestressed structure are used as grouting pipes. It can be tied directly to the steel frame soil, and the joints can be connected with one size larger corrugated socket. Because the bellows is very light, it is very easy to operate, but care must be taken to keep its axis straight during installation. The acoustic impedance of plastic pipes is low. When used as grouting pipes, they have greater sound transmittance and can usually be used for smaller cast-in-place piles. Caution should be used when using large-scale cast-in-place piles because large-diameter piles require grouting. A large amount of concrete, and the heat of hydration of cement is not easy to dissipate. In view of the huge difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after the concrete solidifies, which may cause it to partially separate from the concrete and cause air or The water gap adds more strongly reflective interfaces to the sound path, which can easily lead to misjudgment. The diameter of the grouting pipe is usually larger than the diameter of the radial transducer, and the common specification is the inner diameter. The wall thickness of the pipe has little impact on the sound transmission. Therefore, in principle, there is no limit on the thickness of the pipe wall. However, from the perspective of saving steel, as long as the pipe wall can withstand the lateral pressure of newly poured concrete, the thinner it will be. More provinces.
