Track wall structure and construction method of straddle monorail underground section

Abstract

The invention relates to the technical field of monorail traffic rails, in particular to a straddle type monorail underground section rail wall structure and a construction method thereof. The structure comprises an upper prefabricated wall, a lower cast-in-situ wall and a foundation structure, wherein the upper prefabricated wall is a prefabricated structure, and internal reinforcements downwards extend out ofthe lower surface of the prefabricated structure; and the lower cast-in-situ wall is a cast-in-situ structure, comprises the internal reinforcements of the upper prefabricated wall, extends into the foundation structure, and forms an integrated cast structure with the foundation structure. No buttresses need to be arranged at two sides of the structure; after the buttresses are omitted, the buttress occupation space under the traditional rail beam condition is omitted in the art; and the tunnel end surface is decreased.

Description

Technical field [0001] The invention relates to the technical field of monorail transportation tracks, in particular to a straddle-type monorail underground section track wall structure and a construction method thereof. Background technique [0002] Straddle monorail system is a new type of rail transit mode in which vehicles ride on track beams. Its main characteristics are low investment cost, short construction period, strong adaptability, and small environmental impact. It is suitable for the vast medium-sized cities in my country. Although the straddle monorail is mainly an elevated bridge structure, in the center of the city, especially in the prosperous urban area, restricted by the ground space, the straddle monorail will partially enter the underground. After the straddle-type monorail enters the underground, in order to ensure the manufacturing accuracy of the track, the current tunnel adopts the structural form of buttresses and precast track beams. This structural fo...

AI Technical Summary

Problems solved by technology

After the straddle-type monorail enters the ground, in order to ensure the manufacturing accuracy of the track, the structural form of buttresses and prefabricated track beams is currently used in the tunnel. This structural form makes the load of the train and the load of the track beam itself concentrated on the buttresses, resulting in The size of the buttress foundation is large, which requires a larger section size of the tunnel, which increases the cost of the project and reduces the economy of the straddle monorail
