Abstract

The invention discloses a tunnel excavation construction assisting structural system. The tunnel excavation construction assisting structural system comprises a vertical shaft and a transverse channeland is characterized in that the vertical shaft is vertical to the transverse channel, the vertical shaft and the transverse channel intersect at the bottom of the vertical shaft, a main tunnel excavation opening is arranged in the intersection of the vertical shaft and the transverse channel, and the vertical shaft and the plane where the transverse channel is located are vertical to the excavation direction of a main tunnel. The tunnel excavation construction assisting structural system has the advantages that by arranging the vertical shaft and the transverse channel and allowing the maintunnel to be located in the vertical shaft and the transverse channel, the distance among the vertical shaft, the transverse channel and the main tunnel is shortened greatly, the whole structure is allowed to be located below a traveling road surface, influence on nearby buildings is avoided, and influence of construction on road surface traffic is avoided; the vertical shaft and the transverse channel provides a large construction space for main tunnel excavation, worker and machine entering and exiting are facilitated, and the construction is facilitated.

Description

technical field [0001] The invention relates to the technical field of tunnel excavation, in particular to an auxiliary structure system for tunnel excavation construction. Background technique [0002] With the acceleration of my country's economic growth and urbanization process, the pressure on urban traffic continues to rise, and the process of urban rail transit construction is accelerating. However, due to the complex urban construction environment, dense buildings, staggered pipelines, heavy road traffic, and limited construction space, it has brought challenges to subway construction. At the same time, for special-shaped structures with large sections such as subway stop lines, turnback lines, and crossing lines, the shield tunneling method often used in subway construction is no longer applicable, and the mining method is used for construction. [0003] In the construction of urban tunnel mining methods, the excavation of tunnel mining methods requires the aid of v...
