Embodiment Construction

[0023] In the present invention, a large amount of waste soil and rock produced during the construction of the power station is called reservoir bottom slag 1, and the humus soil layer on the surface is removed, rolled and buried in layers in the dead storage capacity of the reservoir in an idle state.

[0024] figure 1 , figure 2 , image 3 What is shown is the implementation plan in which the water is only blocked by the dam, and the surface layer anti-seepage facilities (protective layer) are not provided on the bank and the bottom of the reservoir. figure 1 represents the concrete gravity dam 2, figure 2 is a concrete face dam, image 3 It is a rockfill dam with a clay core wall 6 . In this scheme, the surface of the slag filling 1 at the bottom of the reservoir is horizontal, and the water inlet and outlet 14 near the forebay 15 are slope-like, and the slag slope angle is smaller than the underwater repose angle of the slag filling, which is the maximum angle to ach...

Abstract

The invention relates to a reservoir bottom slag-embedding structure, which can reduce occupied area and reduce the cost without polluting the environment. It is characterized in that: embedding slag into the dead reservoir at the water accumulation side of reservoir dam. The invention can be used in small reservoir with small flow section.

Description

technical field [0001] The invention relates to a structure for filling waste slag at the bottom of a reservoir. It is suitable for power station reservoirs with small drainage areas, such as upper and lower reservoirs of pumped storage power stations, water supply reservoirs, etc. Background technique [0002] In the construction of a power station, a large amount of waste earth and stone will inevitably be produced. Generally speaking, the volume of waste earth and stone in a large-scale project is often as many as several million, or even tens of millions of cubic meters. For these soil and rock waste materials, the usual way to deal with them is to select a special site near the project area to store the waste slag. The problems in this treatment method are: 1) The construction of the waste slag field and the road to the waste slag field It will occupy a large amount of land resources and cause damage to the environmental vegetation of the waste dump site; 2) The waste ...
