Strength calculation method of underground high-stress blocking retaining wall and wall body thereof

Abstract

The invention relates to a method for calculating the strength of an underground high-stress blocking retaining wall and a wall body thereof. The method comprises the following steps: S1, calculating the maximum impact pressure of debris flow and the maximum impact pressure of water sand; s2, calculating the bearing pressure of the retaining wall; the underground high-stress blocking retaining wall comprises a wall body, the wall body comprises an arc-shaped top plate and a bottom plate arranged on the lower portion of the arc-shaped top plate, and a space for pouring concrete is formed between the arc-shaped top plate and the bottom plate. The invention has the advantages that: 1, by adopting the design of the arc-shaped top plate, the strength of a key stressed part is enhanced, and the instantaneous resistance strength is increased; round steel is arranged around the wall body in the tangential direction of the arc-shaped top plate, the compressive strength of the round steel is utilized to the maximum extent, and the stability of the retaining wall is enhanced;

Description

technical field [0001] The invention relates to a method for calculating the strength of an underground high-stress sealing retaining wall and the wall thereof, and relates to the field of mines. Background technique [0002] Mine water damage refers to any mine water that affects production, mining face or mine safety, increases the cost per ton of mine, and partially or completely floods the mine. As the saying goes: "Water and fire are ruthless" and "Where the fire burns, the water overflows". Once water seepage occurs in the mine, it may cause "group death and group injury" and heavy property loss, and the social response will be great. The prevention and control of water hazards in gold mines is not only related to the healthy development of enterprises, but also to the safety of employees. After inspecting the site, analyzing the cause of the accident, and combining the water prevention and control measures "prevention, blocking, dredging, drainage, and interception"...

AI Technical Summary

Problems solved by technology

[0003] At present, most gold mines use hollow bricks, blue bricks or ordinary concrete for sealing waste and old buildings. Generally, it is only used for isolation and preventing personnel from entering. Any sealing method is acceptable, but there is a hidden danger of water inrush in the stope. The purpose of water control cannot be achieved by using ordinary plugging methods
