Universal hydraulic steel formwork trolley for full-section curved section and straight section of flat tunnel

Abstract

Provided is a tunnel flat hole curved section and straight section full section general hydraulic steel mold trolley. The trolley includes a square needle beam, main templates mounted on the needle beam and multiple leg structures mounted on the needle beam, each leg structure includes a hydraulic lifting column fixedly connected with the needle beam and a rail wheel hinged to the lower end of thehydraulic lifting column, the needle beam comprises a plurality of folding beams arranged in sequence, seaming templates are separably arranged between the adjacent two main templates, the adjacent two folding beams are connected by a telescopic bending mechanism, and the telescopic bending mechanism includes a plurality of bending mechanisms disposed at the upper ends of the folding beams and aplurality of telescopic mechanisms disposed at the lower ends of the folding beams; the trolley is used for solving the problem of frequent assembling and disassembling of the seaming templates between the main templates when the adjacent trolleys move between a curved hole section and a flat hole section.

Description

technical field [0001] The invention relates to a general-purpose hydraulic steel formwork trolley for the full section of the curved section and the straight section of the flat tunnel. Background technique [0002] At present, my country's undeveloped hydropower projects are mostly concentrated in the western mountains and valleys, and most of them adopt the form of underground powerhouses. The steep diversion tunnel consists of an upper flat section, an upper curved section, an inclined shaft, a lower curved section, and a lower flat tunnel. Lining the upper and lower bends of the water diversion tunnel and the full-section of the inclined shaft has become a difficult point in the construction of the water diversion system of hydropower projects. The conventional construction method is to set up load-bearing bent frames with combined assembled formwork. The concrete construction of the inclined shaft section can use sliding formwork or integral lifting formwork, and the o...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a general-purpose hydraulic steel formwork trolley for the full section of the curved section and the straight section of the flat tunnel, which is used to solve the gap between the main formwork when the adjacent trolley moves between the curved section and the flat section. The problem of frequent disassembly and assembly of patchwork formwork
