Permeable tailings pond seepage drainage structure

Abstract

The invention discloses a permeable tailings pond seepage drainage structure. A horizontal seepage drainage body, a vertical seepage drainage body and a water drainage pipe jointly form a water drainage system, wherein seepage drainage pipes in the horizontal seepage drainage body and the vertical seepage drainage body are connected and communicated by using communicating vessels; and a horizontal seepage drainage pipe of the horizontal seepage drainage body is connected and communicated with the water drainage pipe by using the communicating vessels. Seepage drainage systems are sequentially buried in a tailings accumulation dam. The seepage drainage pipes are formed by packaging filter screens on seepage drainage pipe bodies; the seepage drainage pipe bodies are provided with seepage drainage grooves; the bottoms of the seepage drainage grooves are provided with seepage drainage holes communicated with the insides of the seepage drainage pipe bodies. The vertical seepage drainage body and the horizontal seepage drainage body are used together or independently to accumulate water, and the horizontal seepage drainage body and the water drainage pipe are used to lead water so as to drain water in the seepage drainage body out of the dam; and the seepage drainage structure adopts the seepage drainage bodies and the water drainage pipe which can be cleaned and dredged. The seepage drainage system has the advantages of high permeability, small air resistance, good seepage drainage effect and convenient, economic and durable later maintenance and management.

Description

technical field [0001] The invention relates to a seepage drainage facility for tailings ponds, in particular to a permeable tailings pond drainage structure for reducing the infiltration line of dam bodies such as tailings ponds, red mud ponds, and ash silts. Background technique [0002] Tailings ponds, red mud ponds, ash silts and other dams are affected by their own characteristics. When the accumulations in the ponds reach a certain height, the infiltration line of the dam body is generally very high, which seriously affects the safety of the dam body. In order to solve this problem, the design usually pre-sets horizontal drainage bodies or horizontal-vertical combined drainage bodies on the dry beach in the reservoir. The horizontal-vertical combined seepage drainage body has been widely used in some large tailing ponds in recent years due to its good seepage drainage effect. Poor water durability and difficult to maintain. Contents of the invention [0003] The te...
