Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] As shown in the figure, a concrete water collection well 10 is provided under the tailings dam 11, and a frame drainage body 12 is arranged in the tailings pond. The frame drainage body 12 is composed of a vertical column type drainage pipe 7 and a horizontal The beam-type drainage pipes 8 are connected by connectors, the floor height of the beam-type drainage pipes is 3-5m, and the distance between adjacent column-type drainage pipes 7 is 50-100m.

[0035] The node connection between the column type drainage pipe 7 and the horizontal beam type drainage pipe 8 can be orthogonal (such as image 3 ), can also be skewed (such as Figure 4 ), the beam-type seepage drainage pipe 8 is arranged inclined downward, and the inclination angle is between 45°-90°. To facilitate the discharge of water in the dam.

[0036] Such as Figure 5-7 As shown, the connec...

Abstract

The invention discloses a framework type seepage drainage system and a method, and belongs to the field of sewage drainage in a tailing pond, which aims at solving the problem of difficulty in drainage of tailing water in the tailing pond. The framework type seepage drainage system is characterized in that a framework seepage drainage body is arranged in the tailing pond, and is formed by connecting a column type seepage drainage pipe on the vertical direction and a beam type seepage drainage on the horizontal direction through a connector; seepage drainage holes are uniformly distributed in the column type seepage drainage pipe, and water seepage holes are uniformly distributed in the upper half part of the beam type seepage drainage pipe; a geotechnical cloth is coated at the outer sideof the beam type seepage drainage pipe. The framework type seepage drainage system has the advantages that the occurrence of dam collapse accidents is prevented, the safety of lives, properties and existing facilities at the downstream zone is guaranteed, and the serious environmental pollution is prevented.

Description

technical field [0001] The invention belongs to the field of seepage drainage in tailing ponds, and in particular relates to a frame-type seepage drainage system and method. Background technique [0002] According to the statistical analysis of the actual accident data of tailings accumulation dams in my country, the dam seepage damage accidents are in the forefront of the causes and probability of various accidents. The tailings accumulation dam itself is a hydraulic structure built of granular materials. During the operation process, there is a high potential energy water level upstream, and the dam body forms a complex seepage field. Under the action of seepage, when the actual hydraulic gradient reaches or exceeds the critical hydraulic gradient, the dam body will undergo seepage deformation such as piping, soil flow, contact flow soil, contact loss, etc., resulting in overall failure, and even dam failure. Lowering the dam soaking line is the most effective way to impr...
