Trolley for construction of rectangular box culvert and tunnel

Abstract

The invention discloses a trolley for construction of a rectangular box culvert and a tunnel. The trolley comprises a steel supporting frame (1) and lateral plate molds (3). The lateral plate molds (3) are connected with the steel supporting frame (1) through lateral supporting rods (4). Counter-force carriages (6) are arranged at the top of the steel supporting frame (1). One ends of transverse moving beams (5) are connected with the corresponding lateral plate molds (3), and the other ends of the transverse moving beams (5) are inserted into the corresponding counter-force carriages (6). Transverse moving power devices are arranged between the transverse moving beams (5) and the top of the steel supporting frame (1). Vertical supporting lead screws (2) are arranged at the bottom of the steel supporting frame (1). The trolley for construction of the rectangular box culvert and the tunnel has the characteristics of being simple in structure, easy to operate, wide in application range, good in concrete pouring forming quality and high in universality, and is particularly suitable for construction of various open-cut box culverts, pipe galleries and tunnels.

Description

technical field [0001] The invention relates to a construction trolley, in particular to a construction trolley for rectangular box culverts and tunnels. Background technique [0002] There are two main methods of traditional large rectangular box culvert and tunnel construction, one is the whole rectangular box culvert and the tunnel adopts the construction method of full support + wooden formwork, the other uses single-sided wall formwork on both sides, and the roof adopts full support + The construction method of wooden formwork. Both of the above two construction methods have disadvantages such as poor concrete forming effect, limited operating space during construction, long installation and disassembly process of formwork and support, high labor intensity of workers, high construction cost, and low construction efficiency. Single-sided wall formwork is used. During construction, it is necessary to install embedded parts in the concrete, which will affect the construct...

AI Technical Summary

Problems solved by technology

The vertical formwork and demoulding process of the side formwork requires two cylinders with different movements, the side formwork lifting cylinder and the side formwork cylinder. Since the two movements in different directions will conflict with the formwork, it is necessary to move the sideform in the vertical direction. Set the side form chute corresponding to the side form cylinder, which brings a lot of uncertainty to the walking track of the side form, and the operation process is complicated, the side form is easily not supported properly, and there is a misalignment between the side form and the axillary formwork and gaps

Although this technical solution can meet the simultaneous pouring of side wall concrete and roof concrete, the structure is too complicated, the cost of equipment manufacturing and maintenance is high, and the operation is difficult
