AI Technical Summary

Technical Problem

Existing survey equipment is unable to accurately determine whether there is water flow at the bottom of faults and caves due to the influence of magnetic fields, resulting in poor survey results.

Method used

The method combines a miniature radar detector and a drilling device with negative pressure pump technology. The miniature radar detector detects faults and karst caves, the drilling device collects samples, and the negative pressure pump and filter screen collect interstitial water. The source of the water flow is determined by combining ion ratio and pH value.

Benefits of technology

It enables accurate detection of whether there is water flow at the bottom of faults and karst caves, improving the accuracy and efficiency of the detection. It can determine the source of water flow by detecting the concentration of characteristic ions and pH value.

Abstract

The invention belongs to the technical field of testing, particularly relates to surveying equipment for water conservancy and hydropower engineering construction, and aims to solve the problem of poor surveying effect caused by the fact that existing surveying equipment cannot accurately conduct surveying work on the condition that water flow exists in a fault and a karst cave bottom or not due to the influence of a magnetic field. The shell is fixedly connected to the top of the frame; the lifting device is arranged on one side of the frame; the damping device is arranged at the bottom of the lifting device; the surveying device is arranged on one side of the damping device; the drilling device is arranged at the bottom of the surveying device; the filter pressing device is arranged on the drilling device; the collecting device is arranged on the shell; whether water flow exists at the fault and the bottom of the karst cave or not can be accurately surveyed, and therefore the purpose of improving the surveying effect is achieved.
