Drilling hole acoustic radar detection method and drilling hole acoustic radial scanning probe

Abstract

The invention discloses a drilling hole acoustic radar detection method and a drilling hole acoustic radial scanning probe. The method and device have two working modes, namely a drilling hole acoustic common-depth scanning work program and a drilling hole acoustic common-angle radar scanning work program. The drilling hole acoustic radial scanning probe comprises a position controller (1), an exploring tube (2), a sensor adherence elastic arm (3), an acoustic sensor, a rubber assistance pad (4) and an elastic arm locking and trigger switch (5). According to the method and the probe, the technical problem of radial detection by utilizing hole drilling can be solved, the functions of an exploratory hole are sufficiently utilized, so that the detection capacities for deep bury and small geological flaw can be improved, identification to karst caves and other geological flaw abnormality can be distinguished directly and the working efficiency is high. The drilling hole acoustic radar detection method and the drilling hole acoustic radial scanning probe can be widely applied to geological survey, basic potential hazard troubleshooting in municipal, housing, traffic, water conservancy and hydropower and other construction fields.

Description

technical field [0001] The invention relates to a drilling acoustic wave radar detection method and a drilling acoustic wave radial scanning probe, belonging to the field of engineering geological detection. Background technique [0002] Geological prospecting is an investigation and research activity that conducts geological exploration and detection through various means and methods, determines the appropriate bearing layer, determines the foundation type, and calculates the foundation parameters according to the foundation bearing capacity of the bearing layer. Among them, physical exploration is referred to as geophysical prospecting, which is based on the differences in physical properties such as density, magnetism, electricity, elasticity, and radioactivity of various rocks and ores, and uses different physical methods and geophysical instruments to detect natural or artificial geophysical fields. By analyzing and studying the geophysical prospecting data obtained, in...

However, these methods have their own limitations, the detection range is small, the detection results are not accurate enough, and the work efficiency is not high, and geological defects such as existing karst caves cannot be directly detected. Therefore, there is still a lack of a better method in the prior art. Borehole Acoustic Radar Detection Method
