Flood drainage system for valley-type tailing pond

Abstract

The invention belongs to the technical field of tailing ponds, and in particular relates to a flood drainage system for a valley-type tailing pond. The flood drainage system comprises an initial-stage dam arranged at the downstream of the tailing pond and a flood dam arranged at the upstream of the tailing pond, wherein a backwater tank for collecting tailing pond backwater and a stilling basin are arranged at the downstream of the initial-stage dam; a main flood drainage tunnel is arranged between the initial-stage dam and the flood dam; a retaining wall is arranged in the main flood drainage tunnel and then divides the main flood drainage tunnel into a clean water side and a waste water side, the upstream of the clean water side of the main flood drainage tunnel is connected with the flood dam, the downstream of the clean water side of the main flood drainage tunnel is communicated with the stilling basin, and the waste water side is communicated with the backwater tank. The flood drainage system for the valley-type tailing pond can effectively solve a flood and sewage distribution problem of the valley type tailing pond.

AI Technical Summary

Benefits of technology

By placing an anti-flooding dune near the entrance of a canal that separates two areas where there may have high levels of contamination (such as waste) flowed towards each other during heavy rain periods. To save money and protect public health, this area needs to be kept dry out before being refilled. Additionally, installing a barrier called a temporary storage tank at the end allows backpressure to pass between them when filling new waters without causing damage. Overall, these improvements improve efficiency and reduce costs associated with treatments involving sedimentation tanks.

Problems solved by technology

This patented technical solution described in the text describes how current methods of disposal involve draining heavily loaded waters off landfill areas where they may cause damage during construction projects due to overfitting conditions caused by sedimentation basins (gravel) and other factors like erosion. There have been proposes various ways to reduce these issues while still allowing for effective treatment without requiring significant capital outlays.
