Problems solved by technology

[0004] The first object of the present invention is to provide a tunnel excavation lining construction trolley to solve the problem that the traditional secondary lining construction equipment needs to remove the temporary supports such as the middle partition wall and inverted arch step by step, and then the secondary lining can be divided into sections. The pouring of the secondary lining greatly reduces the work efficiency and delays the technical problem of the construction period

Abstract

The invention discloses a tunnel underground excavation and lining constriction trolley and a tunnel underground excavation and lining construction method. The tunnel underground excavation and lining trolley comprises a trolley support system and a trolley formwork system; the trolley support system comprises a support system frame, a vertical hydraulic device, an upper vertical pole, a horizontal hydraulic device and a horizontal pole; the trolley formwork system comprises a formwork system frame, a jacking hydraulic oil cylinder, a longitudinal beam, a chord member and a formwork adjusting lead screw. According to the tunnel underground excavation and lining constriction trolley and the tunnel underground excavation and lining construction method, a CRD construction method is effectively improved, by means of the trolley support system, a temporary support system can break median lamella and an inverted arch in one time, the construction period is greatly shortened, and the construction cost is saved; secondary lining is achieved through one-time steel bar binding and pouring, construction joints caused by multiple formworking are reduced, water seepage hidden danger is reduced, and the strength of secondary lining, the smoothness of the outer surface and the overall flatness of concrete are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tunnel excavation construction equipment and methods, and in particular relates to a tunnel excavation lining construction trolley and a tunnel excavation lining construction method realized by using the trolley. Background technique [0002] In the current existing technologies, there are many patents on trolleys for secondary lining construction operations. Usually, the main focus is on the functionality and mobility of formwork trolleys, without considering the impact of the temporary support system on the secondary lining construction during the construction process. For example, China Patent No. "201410596838.1" discloses a tunnel lining trolley. The formwork trolley includes a formwork assembly matching the tunnel contour. Due to the lack of a support system for the outer periphery, the use of the trolley under adverse geological conditions is restricted; For example, a tunnel lining trolley disclos...
