Problems solved by technology
The capacity of the tailings pond gradually increases with the increase of the dam body. Once the dam body fails, tailings sand, mud, and water will gush out in the form of debris flow, posing a threat to the lives and properties of downstream residents.

Embodiment
[0043] a) The length of the observation device used in the tailings pond of a concentrator is 15m and 20m. (The schematic diagram of this patent takes the 20m observation hole tube as an example)
[0044] b) Use roller cone drilling equipment to drill a well hole with a diameter of 250mm on the dam body and a depth of 20m;
[0045] c) The height of the exposed surface of the observation device is 1m; the thickness of the concrete protective layer is 1000mm, and the middle pipe section of the observation hole is a PVC pipe with a diameter of 100mm, and the length of each PVC pipe is 3m, and the pipes are connected by pipe hoops;
[0046] d) Lower the completed observation device into the wellbore. Since the lower end of the observation pipe is close to the dam body's soaking line, and the bottom contains a lot of sediment, it is necessary to seal the end of the pipe with a metal steel ingot to prevent a large amount of mud from pouring into the well. observation device. When ...

The invention relates to an auxiliary device for observing the water level by a tailing pond saturation line and a construction method. The auxiliary device is characterized by comprising a PVC (Polyvinyl Chloride) pipe section at the upper part, a water filter pipe section connected with the PVC pipe section through a nut, and a metal steel ingot arranged at the lower part of the water filter pipe section, wherein a stainless steel protection pipe is arranged at the outer side of a ground exposing part of the PVC pipe section; a dustproof cover is arranged at the end part of the stainless steel protection pipe; the water filter pipe section is composed of a PVC pipe of which two ends are provided with outer threads and the middle part is uniformly provided with permeable holes, geotextile which is cladded on the outer side of the PVC pipe, and a galvanized steel wire gauze which is cladded on the outer side of the geotextile. The auxiliary device provided by the invention has the beneficial effects that: an observation device is arranged on a tailing pond dam body; because the observation mode of the observation device belongs to manual observation, the operation is simple and the numerical error of observed water level is small, the change of the water level of the saturation line inside the dam body can be timely observed at the fixed period so as to check, verify, design, better apply and manage the tailing pond.
Description
technical field [0001] The invention relates to the technical field of observing the water level inside a tailings dam body, in particular to an auxiliary device for observing the water level of the infiltration line of a tailings dam and a construction method. Background technique [0002] The tailings pond is an important part of the production facilities of the concentrator. Whether the tailings pond can operate safely and stably plays a vital role in the production of the concentrator, and it is also a major source of danger. Because the tailings pond of Gongchangling concentrator is made of tailings sand, a large amount of tailings and water are piled up in the dam body, forming an artificial "tailings lake". The capacity of the tailings pond gradually increases with the increasing height of the dam body. Once the dam body fails, tailings sand, mud, and water will gushes out in the form of debris flow, posing a threat to the lives and properties of downstream residen...
