Pile body quality electrical method detection method

Abstract

The invention discloses a pile body quality electrical method detection method which comprises the following steps: Step 1, selecting a first power supply point on one side surface of a pile body andrecording a coordinate position, selecting a plurality of second power supply points on the other side surface and recording coordinates, and selecting a plurality of observation points on the pile body and recording coordinates; Step 2, arranging a first power supply electrode at a first power supply point, and arranging a second power supply electrode at one second power supply point; Step 3, supplying power to the first power supply electrode and the second power supply electrode; Step 4, collecting electric field data of each observation point; Step 5, moving the second power supply electrode to the next second power supply point, and repeating the steps 3-4 until all electric field data from the first power supply point to each second power supply point is acquired; and Step 6, performing data inversion on all the electric field data in combination with the coordinate position to obtain the position and size of the abnormal body. According to the method, the electrical prospectingtechnology can be applied to the field of pile body quality detection forming a three-quarter space with the ground, and the position and the size of an abnormal body can be effectively detected.

Description

Technical field [0001] The invention belongs to the technical field of electrical detection, and in particular relates to an electrical detection method for the quality of a pile. Background technique [0002] Electrical exploration is generally used in geological prospecting. Through the observation and research of the spatial distribution and time characteristics of artificial or natural electric, electromagnetic or electrochemical fields, it is possible to search for different types of useful mineral deposits, ascertain geological structures and solve geological problems. Exploration methods. The application of this technology in civil engineering inspection can effectively warn of potential safety hazards in the internal structure of reinforced concrete in service. [0003] In the field of concrete quality inspection, such as deep-buried piles, such as bridge piers, foundations, etc., these components form three-quarters of the space with the earth. Generally, sound waves, cor...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, it is difficult for sound waves to penetrate concrete, especially when facing thicker piles, so the detection effect is not good, and core drilling and vibration detection will cause damage to the pile

However, it is difficult to directly use the existing electrical prospecting technology on the pile body.
