Problems solved by technology

[0002] In the prior art, tunnels in subway intervals are generally constructed using the shield tunneling method, and tunnels in subway intervals constructed using the mining method are less than those constructed using the shield tunneling method, and because the interval tunnels are generally shorter, when the mining method is used for construction, fewer auxiliary tunnels are set up. When setting inclined shafts in other similar projects, the construction at the intersection of inclined shafts and main tunnels is extremely complicated

Abstract

The invention provides a double-line mining method subway tunnel inclined well entering main tunnel structure. The structure comprises a first support wall for supporting an inclined well, a second support wall for supporting a main tunnel, and an intersection part for extending the inclined well to intersect with the main tunnel, wherein the top, near the intersection part, of the inclined well is upwards inclined to expand to the intersection part; the intersection part is higher than the main tunnel; the intersection part has a third primary support structure; a space is formed by the third primary support structure and the second support wall; the space and the inclined well near the intersection part are both refilled by mortar rubbles; and the structure solves the technical problems of a simplified construction method of the inclined well entering the main tunnel, and achieves the excellent effects of effectively shortening the construction period and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to providing a structure and a process method for an inclined shaft entrance tunnel of a subway tunnel with a double-track mining method. Background technique [0002] In the prior art, tunnels in subway intervals are generally constructed using the shield tunneling method, and tunnels in subway intervals constructed using the mining method are less than those constructed using the shield tunneling method, and because the interval tunnels are generally shorter, when the mining method is used for construction, fewer auxiliary tunnels are set up. When setting inclined shafts in other similar projects, the construction at the intersection of inclined shafts and main tunnels is extremely complicated. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the main purpose of the present invention is to provide a structure and a process method ...
