Dingxi bridge acoustic tube/Yulin 50 acoustic tube/Anqing 57 acoustic tube

Dingxi Bridge Acoustic Detection Pipe/Yulin Acoustic Detection Pipe/Anqing Acoustic Detection Pipe Manager Zhang’s pre-embedded acoustic detection pipe pile diameter should be buried with two pipes. Three pipes should be buried with the pile diameter. Four pipes should be buried on the pile diameter. The acoustic detection tube should be made of steel pipe, and its inner diameter should be ~. The joints of the acoustic detection tubes should have smooth transitions, the tube openings should be higher than the top of the pile, and the height of the openings of each detection tube should be consistent. The lower end of the tube should be closed, and the upper end should be capped. There should be no foreign matter in the tube, and the tube body should not be damaged. The acoustic detection tubes can be welded or bundled on the inside of the steel bars, and the detection tubes should be parallel to each other. The acoustic tube should be filled with clean water. On-site inspection of acoustic tubes. Before on-site inspection, measure the delay time from the acoustic monitor to the receiving system. And calculate the sound time correction value. During measurement, the transmitting and receiving probes should be raised and lowered synchronously at the same altitude or with a fixed height difference. The measurement point distance is , and when an abnormality is found, it is encrypted to select the appropriate transmit voltage and amplifier gain, and remains unchanged during the test process. Display and record the time course curve of the received signal in real time. Multiple acoustic detection tubes are combined into two as one detection section, and multiple sections are tested separately. After each group of acoustic test tubes is tested, the test points should be randomly tested repeatedly, and the relative standard deviation of the acoustic time should not be greater than the relative standard deviation of the amplitude. Dingxi Bridge Acoustic Detection Tube/Yulin Acoustic Detection Tube/Anqing Acoustic Detection Tube Spiral Ultrasonic Detection Tube and its Features: Spiral Ultrasonic Detection Tube Convenience Spiral Ultrasonic Detection Tube Simple Connection The acoustic detection tube does not require on-site welding. It adopts spiral connection and spiral Driven by double buckles, locking sealing rubber rings, and axial end seals, it effectively prevents loosening and leakage, is convenient, fast, safe, reliable, and reduces costs. Installing each joint takes less than a minute, significantly saving man-hours and eliminating the need for any technical support. No preparation work outside the construction site is required. No equipment is required. It is simple and fast. It is twice as fast as the traditional method. It is easy to be fixed on the steel cage and is not affected by bad weather. The two-spiral ultrasonic detection tube is economical in the drilling and pouring construction of deeper bridges. The specifications for the borehole pouring inspection require that the acoustic transmission method be used to detect the quality of the pile foundation. According to the design requirements, acoustic detection pipes should be buried. Three pile foundations with ordinary pile diameters need to be buried. In conventional design, it is generally required to use steel pipes with an outer diameter and a thickness of Right, external casing is used for on-site welding during construction. This method requires higher costs. The construction cost of the acoustic pipe produced by our company only accounts for about the construction cost of ordinary welded pipe, which greatly reduces the construction cost. Dingxi Bridge Acoustic Detection Pipe/Yulin Acoustic Detection Pipe/Anqing Acoustic Detection Pipe Three-spiral Ultrasonic Detection Pipe Safety Bridge pile foundations have particularly strict requirements on the acoustic pipe sealing, leakage resistance and pressure resistance during concrete pouring. There are slightly It will not cause pipe blockage or pipe deformation. During the construction of ordinary welded pipes, each construction team is responsible for the welding work of the acoustic pipe. It is difficult to ensure the quality without detecting the sealing and leakage resistance of the pipe wall interface and pipe bottom seal. The acoustic pipes produced by our company must pass three inspection procedures, namely, initial inspection, gas inspection, and water inspection, to ensure that the products meet the construction technical requirements.
