Flexible pile detection system and method

Abstract

The invention relates to the field of civil engineering, in particular to a flexible pile detection system and method. The system comprises two drill holes formed in soil bodies on the two sides of aflexible pile. The drill hole is filled with a conductive medium; the two drilling holes are respectively and internally provided with an electrode, the electrodes are connected with the ground through a suspension device with adjustable lowering depth, the two electrodes are both connected with a data measuring and processing device, and the data measuring and processing device is used for loading voltage to the two electrodes and measuring the current between the two electrodes. By measuring the current and the voltage between the two electrodes, the resistivity of the two sides of the flexible pile is calculated according to the ohm law; when the pile body of the flexible pile generates necking, pile breaking phenomena and the like, the resistivity inevitably changes, the integrity of the pile body of the flexible pile can be judged according to the change of the resistivity, and the occurrence position of pile defects can be determined.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a flexible pile detection system and method. Background technique [0002] As a hidden project, the pile foundation project has complex construction technology, many uncertain factors, difficult construction, and is prone to quality problems. The quality of the pile foundation is related to the safety of the entire project, so the quality inspection of the pile foundation is very important. Flexible pile refers to the pile body with a certain strength formed by mixing cement, lime and other bonding materials with soil, and forms a composite foundation with the soil around the pile. It has the advantages of wide application range, high degree of mechanization, fast construction speed, and low cost. Widely used in pile foundation engineering. At present, there are many pile foundation quality detection methods, such as low-strain method, high-strain method, acoustic transmission m...

AI Technical Summary

Problems solved by technology

At present, there are many pile foundation quality detection methods, such as low-strain method, high-strain method, acoustic transmission method, core-drilling method, static load test, etc., but for flexible piles, the inspection results of existing detection methods are not ideal. Cause certain damage to the original structure, easy to cause misjudgment when testing flexible piles with low strain method, etc.
