Novel internal mould trolley walking device for carriageway in prefabrication of immersed tube tunnel tube segment

Abstract

The invention relates to the field of immersed tube prefabrication construction technological structures, in particular to a novel internal mould trolley walking device for a carriageway in the prefabrication of an immersed tube tunnel tube segment. The novel internal mould trolley walking device comprises an internal mould trolley; at least two internal mould fixed supporting legs and at least two internal mould movable supporting legs are arranged at the lower end of the internal mould trolley; the internal mould fixed supporting legs are supporting structures of which the upper ends are fixed to the internal mould trolley and can contract and stretch in the vertical direction; the internal mould movable supporting legs are the supporting structures of which the upper ends can be connected to the internal mould trolley in a manner of sliding in the longitudinal direction and the transverse direction and the lower ends can contract and stretch in the vertical direction; and the internal mould fixed supporting legs and the internal mould movable supporting legs are arranged on the internal mould trolley at intervals in the vertical direction. According to the walking structure disclosed by the invention, the position regulation of the internal mould trolley in the longitudinal direction, the transverse direction and the vertical direction can be realized; the efficiency of immersed tube casting construction is improved; and the novel internal mould trolley walking device has great popularization value.

Description

technical field [0001] The invention relates to the technical structure field of immersed tube prefabrication construction, in particular to a new type of traveling device for an inner mold trolley of a prefabricated roadway in an immersed tube tunnel section. Background technique [0002] During the prefabrication construction process of the immersed tube section, the inner mold of the roadway needs to be transferred repeatedly to realize the segmental prefabrication of the immersed tube section. The traditional internal mold transition adopts manual disassembly and assembly or a needle beam trolley with guide beams to transfer the entire internal mold. The internal mold is transferred by manual disassembly and assembly, which has a large amount of disassembly and assembly, which greatly increases the construction period and cost, and the production efficiency is low; the entire internal mold is transferred by using a needle beam trolley with guide beams, which is more effi...

AI Technical Summary

Problems solved by technology

The internal mold is transferred by manual disassembly and assembly, which has a large amount of disassembly and assembly, which greatly increases the construction period and cost, and the production efficiency is low; the entire internal mold is transferred by using a needle beam trolley with guide beams, which is more efficient than manual The disassembly method is convenient to use, but the structure of the needle beam trolley with the guide beam is self-heavy and occupies a large space, which increases the construction cost, and the inner mold and the trolley are moved separately. First move the needle beam with the guide beam forward to the prefabrication position of the next segment, and then move the inner mold on the needle beam to the prefabrication position of the next segment. It needs to be moved twice to transfer the inner mold trolley in place
