Description

Technical Field

[0001] This application belongs to the field of machinery and construction of driven stone piles, and particularly relates to the field of real-time detection of pile diameter during the pile formation process of driven stone piles, specifically involving a transducer bearing device and its manufacturing method. Background Technology

[0002] Currently, the quality inspection requirements for crushed stone piles in standards such as the "Technical Specification for Composite Foundations" and the "Technical Specification for Building Foundation Treatment" only require the use of dynamic penetration tests to detect their compaction and pile integrity. This testing method cannot detect the pile diameter or determine the uniformity of the pile body. During the crushed stone pile formation process, issues such as diameter expansion, diameter reduction, and even pile breakage frequently occur. Diameter expansion leads to material waste and increased costs, while diameter reduction and pile breakage can cause quality defects and safety hazards in the project. To monitor the diameter of driven crushed stone piles during the formation process, ultrasonic monitoring can be used in real time. However, this method requires the transducer to be installed at the bottom of the steel pipe of the driven crushed stone pile machine. Therefore, a bearing device that can protect the transducer and withstand the huge vibration force during pile formation needs to be designed to achieve the detection of the pile diameter.
