Wiring waterproof device for well-drilling well wall monitoring sensor and waterproof sealing method

Abstract

The invention relates to a wiring waterproof device and a waterproof sealing method for a well-drilling well wall monitoring sensor, the wiring waterproof device comprises a wiring cylinder, the wiring cylinder is sleeved on a lead connected with the sensor, the wiring cylinder is filled with epoxy resin, and threaded caps are screwed outside two ends of the wiring cylinder. The problem that a sensor in a water-containing soft stratum is prone to water inflow failure is solved, a first waterproof layer is formed by conducting waterproof treatment on a wire of the sensor, a second waterproof layer is formed by conducting waterproof treatment on a first junction box, and a third waterproof layer is formed by conducting waterproof treatment on the first junction box and a second junction box. Normal work of the monitoring sensor is ensured through three waterproof layers, and normal and orderly development of monitoring and analysis work is ensured, so that the purpose of popularizing application of well sinking in a water-containing soft rock stratum through a drilling method is achieved. The waterproof sealing method can effectively prevent underground water from entering the sensor to cause failure of the sensor, and guarantees the stability and credibility of monitoring data.

Description

technical field [0001] The invention relates to the technical field of well-sinking information construction by drilling method, in particular to a waterproof device and a waterproof sealing method for the wiring of monitoring sensors on the well wall of a well. Background technique [0002] When building new deep shafts in some mining areas, they will pass through deep, thick, water-bearing and weak strata. Water, and it is a pore-fracture aquifer, the effect of grouting to seal water is poor, and it is difficult to pass through the common method of construction, so a special method is required to drill the well. Among them, the well drilling method has the advantages of safe construction, high degree of mechanization, reliable well wall quality, and no risk of water conduction through frozen holes after the well is completed. It is a construction method that needs to be popularized and applied. [0003] In order to analyze the reliability of the borehole wall and ensure t...

AI Technical Summary

Problems solved by technology

Due to the large size of the drilling well wall, the wires of each monitoring sensor are long. If the skin of the wire is damaged during the process of buried installation and concrete vibration, seepage water may enter the inside of the monitoring sensor, which will cause the test sensor to fail and cannot be monitored.

In order to ensure the long-term monitoring work, it is necessary to carry out all-round waterproof and sealing treatment on the wiring of the sensor, otherwise, once the groundwater penetrates into the sensor, the accuracy of the test data cannot be guaranteed
