Open type tunnel boring machine (TBM) on-site concrete inverted arch synchronous lining trolley

Abstract

The invention discloses an open type tunnel boring machine (TBM) on-site concrete inverted arch synchronous lining trolley. An upper structure of a trolley comprises a trolley rack and a track section movement system which is formed by a track section crane door frame, track section crane suspension arm beams and a track section crane crack. The trolley track is a whole structure which is formed by fixed connection of a rack cross beam and a bottom longitudinal beam, multiple steel rails are arranged on the rack cross beam in a laying mode, and a front ramp and a rear ramp are respectively arranged at the front end and the rear end of the trolley rack. Multiple sections of health maintenance trestle stand are connected between the rear end of the trolley rack and the rear ramp. Trolley displacement sliding beams are arranged below both sides of the trolley cross beam, the track section crane door frame is arranged on the trolley cross beam, a track section crane track is arranged on the track section crane door frame, and the track section crane suspension arm beams are arranged on both sides of the trolley cross beam. A lower portion of the trolley is composed of a template system which is formed by a template, a lifting oil cylinder, a horizontal oil cylinder, a vertical lead screw and a slant lead screw. The open type TBM on-site concrete inverted arch synchronous lining trolley achieves synchronous construction of open type TBM digging and cast-in-place inverted arch, reduces construction joints, wholly improves tunnel secondary lining cavitation quality, and shortens whole construction period.

Description

Technical field: [0001] The invention belongs to a long tunnel and road construction equipment, in particular to an open type TBM cast-in-place concrete inverted arch synchronous lining trolley, which is suitable for tunnel boring machine construction, continuous belt conveyor or rail transport train It is used under normal operating conditions such as slag discharge and rail transportation. Background technique: [0002] In recent years, the synchronous construction technology of open TBM excavation side-roof arch lining has been realized under the conditions of rail transport train slag discharge and continuous belt conveyor slag discharge, and has been successfully applied in railway tunnel construction. However, inverted arch (or called As the "bottom arch", hereinafter referred to as "inverted arch"), the prefabricated reinforced concrete structure has been used, which is costly and has many construction joints, which is not conducive to ensuring the waterproof quality ...

Problems solved by technology

[0002] In recent years, the synchronous construction technology of open TBM excavation side-roof arch lining has been realized under the conditions of rail transport train slag discharge and continuous belt conveyor slag discharge, and has been successfully applied in railway tunnel construction. However, inverted arch (or called As the "bottom arch", hereinafter referred to as "inverted arch") has been using prefabricated reinforced concrete structure, the cost is high and there are many construction joints, which is not conducive to ensuring the waterproof quality of the tunnel (road) and reducing construction costs
