Automatic drainage system for pile body

Abstract

The invention provides an automatic stack drainage system, and relates to the technical field of stack drainage. An automatic stack drainage system comprises a control unit and a drainage assembly. The drainage assembly comprises a plurality of drainage pipelines and a plurality of air inlet pipelines, and the drainage pipelines extend into the waste water wells in a one-to-one correspondence mode. A first flow sensor is arranged on any drainage pipeline and used for measuring the flow in the drainage pipeline. The first flow sensors are all connected with the control unit, a liquid level sensor is arranged in any observation well and used for detecting the liquid level height in the observation well, and the liquid level sensors are all connected with the control unit. The multiple air inlet pipelines extend into the waste water wells in a one-to-one correspondence mode, the ends, located in the waste water wells, of the air inlet pipelines extend into inlets of the drainage pipelines, the other ends of the air inlet pipelines are connected with the air compression assemblies, and the air compression assemblies are connected with the control unit. According to the invention, drainage control of a large-area pile body can be realized, and the purpose of refined and accurate drainage is achieved.

Description

technical field [0001] The invention relates to the technical field of heap drainage, in particular to an automatic drainage system for a heap. Background technique [0002] Mine tailings, chemical waste slag and domestic waste piles often contain a lot of water, which affects the stability of the pile. At present, the main use of vertical shaft gas flooding is to discharge the water in the pile to increase the strength of the dam body and stabilize the dam body. In the construction, most of the air compressors are directly connected to drive the drainage. When the large-scale implementation is carried out, the gas consumption is large and the energy consumption is high. The drainage cannot be accurately controlled in areas with different water levels, resulting in energy waste. When there are many shafts, the overall drainage control is difficult. The inaccurate determination of the water level at each point of the overall storage yard affects the overall precipitation effi...

Problems solved by technology

[0002] Mine tailings, chemical waste slag and household garbage are often piled with a large amount of water, which affects the stability of the pile. At present, the vertical shaft gas drive drainage method is mainly used to drain the water in the pile, increase the strength of the dam body, and stabilize the dam body. During the construction, most of the air compressors are directly connected to drive the drainage. When implementing in a large area, the air consumption is large and the energy consumption is high. It is impossible to accurately control the drainage in areas with different water levels, resulting in energy waste. When there are many shafts, the overall drainage control is difficult. The inaccurate determination of the water level at each point of the overall storage yard affects the overall precipitation efficiency and the problem of continued storage in the later period
