Observation system for saturation line of dam body of tailing reservoir

Abstract

The invention discloses an observation system for the saturation line of a dam body of a tailing reservoir. The observation system is arranged in the dam body of the tailing reservoir and is composed of a steel tube (1), a steel plug (2), geotextile (4), hemp thread (5), an oil-immersed wooden plug (6) and coarse sand (7), wherein the steel tube (1) is externally coated by the geotextile (4), reversely filtered and firmly bound by the hemp thread (5), and the gaps around the steel tube (1) are filled by adopting the coarse sand (7); the lower part of the steel tube (1) is a sand setting pipe section (11), the middle part is a water filtering pipe section (8), the upper part of the steel tube (1) is exposed out of earth surface and is connected with the steel choke plug (2) by adopting screw thread (3) so as to ensure that the steel tube opening is sealed; the bottom of the steel tube (1) is plugged by adopting the oil-immersed wooden plug (6); and a plurality of holes (9) are arrangedat the water filtering pipe section (8) of the steel tube (1). The observation system for the saturation line of the dam body of the tailing reservoir is high in observation accuracy, simple in data collection and is capable of meeting the saturation line observing requirements of various tailing reservoirs, especially upstream tailing dams and tailing reservoirs and has the characteristics of convenience for observation, longer service life and no influence by factors such as weather, temperature, installation and the like.

Description

technical field [0001] The present invention relates to a dam body infiltration line observation system, in particular to an observation system for the dam body infiltration line of a tailings pond, especially suitable for tailings ponds using upstream tailings for damming to realize the observation of the dam body infiltration line . Background technique [0002] Tailings pond is an important facility in mine production. It is not only an artificially formed high-level debris flow hazard source, but also a source of environmental pollution. It is one of the major hazard sources in non-coal mines. has great practical significance. Tailings ponds built with upstream tailings are widely used in my country due to their low cost. However, due to their relatively low safety and high requirements for dam maintenance and management, in recent years, upstream tailings have been adopted. The frequent occurrence of safety accidents in tailing ponds for damming not only causes losses ...

AI Technical Summary

Problems solved by technology

[0006] (1) The sensitivity of the piezometric tube is easily affected by factors such as the standardization of installation, the rainfall at the nozzle, the service life, the steep rise and fall of the reservoir water level, etc., resulting in large errors in the observation data of the dam soaking line;

[0007] (2) Since the sensor is located in the natural environment of the tailings pond and the working environment is relatively harsh, the accuracy and working status of the sensor are easily affected by factors such as lightning, humidity, rainfall, temperature changes, installation, etc., resulting in distortion of the observation data of the dam body infiltration line
