Sonic Logging Pipe is a metal pipe pre-buried in the cast-in-place pile, mainly used for acoustic wave detection in pile foundation engineering. Its core function is to provide a channel for the ultrasonic detection probe to enter the pile body, ensuring that the detection data accurately reflects the quality of the pile body.

Purpose of Sonic Logging Pipe ‌ ‌ 

As a key channel for ultrasonic detection probes, the sonic detection pipe plays a pivotal role in the pile foundation quality detection system. Its pre-buried method and layout strategy are like notes in a precise movement, directly affecting the accuracy and reliability of the pile foundation integrity detection results. On the initial blueprint of the design, the layout of the sonic detection pipe must be clearly and carefully marked, which is not only a test of the professional quality of engineers, but also a strong guarantee for the precise execution of subsequent construction. The position, spacing and even inclination angle of each sonic detection pipe must be rigorously calculated to ensure that the detection signal can fully and completely cover the entire pile foundation structure without dead ends, revealing any potential defects or abnormalities.

The construction stage is the key step to turn this exquisite design into reality. When burying the sonic detection pipe, quality control is as delicate as carving a work of art, and no deviation is allowed. Construction workers must strictly follow the operating procedures to ensure that the acoustic detection tube is tightly combined with the pile concrete, which can avoid signal attenuation caused by gaps and prevent displacement or damage during the pouring process. In addition, the selection of the material of the acoustic detection tube must also be prudent, not only to meet the requirements of high strength and corrosion resistance, but also to facilitate the smooth insertion and operation of the subsequent detection probe.

In the face of the defect treatment of accident piles, the role of the acoustic detection tube is more prominent. It is like a keen detective, using the "perspective" ability of ultrasonic detection technology to accurately locate the location and nature of the defects, providing a scientific basis for subsequent repair work. During the treatment process, based on the data collected by the acoustic detection tube, engineers can formulate targeted repair plans to ensure that the pile foundation restores its original bearing capacity and stability, and escort the long-term safety of the building.

The acoustic detection tube can be used for flushing and grouting repair of defective parts, and a specific process is required to open the pipeline to achieve defect repair.

‌ Foundation reinforcement ‌ 

In soft foundations, the acoustic detection tube can reduce the thickness of the base layer, reduce the project cost, and extend the service life of the project by enhancing the bearing capacity of the foundation and controlling settlement. ‌5.

As a grouting pipe at the bottom of the pile, the ultrasonic detection pipe can significantly improve the bearing capacity of the bored pile and optimize the performance of the pile foundation.

‌Precautions‌

The joints of the ultrasonic detection pipe must be firmly sealed, and the pipe wall must be flat and without deformation to ensure the accuracy of ultrasonic detection. Improper materials or installation may cause leakage, pipe blockage and other problems, affecting the test results. ‌
