Many advantages: Usually the diameter of the transducer is larger than that of the radial transducer, and the common specification is the inner diameter. The wall thickness of the pipe has little effect on the sound transmittance. 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.
Yiqing acoustic measuring pipes can be easily installed and fixed by welding or binding. The pipes should be basically parallel to each other. If the test results need to evaluate the strength of the concrete at each measuring point, the non-parallelism should be controlled within the following . The steel cage should be prevented from twisting when placed in the pile hole.
Erqing acoustic pipe has a wide range of uses. In addition to being used as a detection channel and replacing part of the steel bar section, the Daqing acoustic pipe can also be used as a pipe for grouting at the bottom of the pile. Tests have proven that cast-in-place piles treated with pile base slurry can significantly increase their bearing capacity. At the same time, the Daqing acoustic pipe can also be used as a pipeline for flushing and grouting treatment of defects in accident piles. At this time, measures need to be taken to penetrate the pipelines in the defective parts that need grouting.

Daqing acoustic tube is a professional manufacturer with reasonable prices, direct sales from manufacturers, better quality, and more favorable prices.
The steel cage should be prevented from twisting when placed in the pile hole. Daqing acoustic pipes are generally installed in sections along with the steel cage. Fix the Daqing acoustic pipe with the bottom cover on the first section of the steel cage, and temporarily fix the rest on the prepared steel cage to be removed. When removing the steel cage, connect the previous section of the Daqing acoustic pipe. Plug it in, and tie the Daqing acoustic tube to the steel cage at the same time, and do it in sequence. The joint between each section can use a reverse-threaded sleeve interface or a casing welding solution. The reverse-threaded sleeve joint should use a soft rubber sealing ring. A long steel sleeve can be selected for the casing connection. The inner diameter is slightly larger than Daqing. To determine the outer diameter of the acoustic tube, put the two Daqing acoustic tubes together, and use electric welding to weld the sleeves to the upper and lower ends of the Daqing acoustic tubes. No matter which joint scheme is used, it must ensure that the joint has sufficient strength to ensure that the Daqing acoustic pipe will not be bent and detached under high hydrostatic pressure. The joint part should be dense and leak-proof. The inner wall of the joint should be kept flat and there should be no welding slag. , burrs and other objects to avoid hindering the free movement of the transducer. If the Daqing acoustic pipe needs to be cut off, it should be cut with a cutting machine. After cutting, the pipe mouth should be polished to eliminate internal and external burrs. When it is not suitable to burn the welding steel bars with electric welding, the welding liquid should be avoided from splashing on the pipe body or joints.
