Description

Excavation construction structure adopting mining diversion vertical shaft

Technical Field

The utility model discloses hydraulic and hydroelectric engineering construction field, concretely relates to adopt mining diversion shaft excavation construction structures.

Background

According to the traditional water conservancy and hydropower engineering, the traditional construction process for deep shaft excavation in the hydropower industry comprises the following steps: processing a wellhead → installing a raise boring machine and constructing a guide hole → constructing a slag flowing well with the diameter of 1.4-2.1 m by the raise boring machine → blasting, excavating and supporting from top to bottom artificially. Because the vertical shaft is deep, the expansion excavation needs to be carried out in a grading way, and the manual blasting construction is adopted, so that the number of the underground constructors is large, the safety risk is high, and the period is long. The existing new excavation mode uses the raise boring machine to perform one-time back-pull forming, the problem that subsequent blasting expanding excavation is not needed any more is effectively solved, the safety risk of deep shaft construction is greatly reduced, and the construction progress of a shaft is improved. However, the excavation to underground mining diversion shaft does not have a reasonable construction structure, because it is narrow at the ground bottom operation construction space, the rig is difficult to arrange, if the excavation space is big, firstly produce other potential safety hazards easily, secondly construction cost is high, leads to diversion shaft construction difficulty, work efficiency's the promotion that is difficult to.
