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 field of construction technology, in particular to provide a double-line mining method subway tunnel inclined shaft into the main tunnel structure and a process method thereof. Background technique [0002] In the prior art, the subway section tunnels are generally constructed by the shield method, and the subway section tunnels constructed by the mining method are less than the shield method. Since the section tunnels are generally shorter, auxiliary tunnels are rarely set when the mining method is used. When inclined shafts are installed in other similar projects, the construction at the intersection of the inclined shaft and the main tunnel is extremely complicated. Summary of the invention [0003] In order to solve the above technical problems, the main purpose of the present invention is to provide a dual-line mine method subway tunnel inclined shaft into the main tunnel structure and its process method. [0004] In order to...
