Fabricated trolley for box culvert construction and construction method thereof

Abstract

A fabricated trolley for box culvert construction is provided. Rails are longitudinally laid on a poured box culvert bottom plate, stand columns with walking wheels and stand columns with adjustable bottom supports A are arranged above the rails in a staggered mode, longitudinal beams are supported above the stand columns, a plurality of sets of bailey beams are erected above the longitudinal beams, and a top formwork is supported above the bailey beams; left and right ends of each bailey beam are connected with end trusses; the side faces of the stand columns are connected with side formworksthrough adjusting screws and jacks. The fabricated trolley is used for pouring a box culvert wall body and top plate concrete at the same time, the box culvert concrete pouring efficiency can be greatly improved, the inner surface and the outer surface of a poured box culvert are smooth, constructors can use the trolley conveniently, and all components of the trolley can be disassembled and installed quickly and are convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an assembled trolley for box culvert construction and a construction method thereof. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. The box culvert is composed of one or more square or rectangular sections. The construction of the box culvert is generally cast-in-place. The bottom layer is set in the excavated trench, a layer of concrete cushion is poured, and the processed steel bars are bound on site. For larger box culverts, the lower half of the bottom plate and side walls are generally poured first, then the upper part of the side walls and the roof reinforcement are bound, the inner and outer molds are supported, and the upper half of the side walls and roof are poured. After the concrete reaches the strength required by the design, the formwork is removed, and the soil is backfilled on both...

AI Technical Summary

Problems solved by technology

[0003] In the process of building the box culvert pouring formwork, due to the closed shape of the outer wall of the box culvert, the formwork forming the inner wall of the box culvert must be built from the inside of the box culvert, but the inner space of the box culvert is small, and in traditional construction, it needs to be built inside the box culvert Scaffolding is advanced section by section, the scaffolding is repeatedly disassembled and assembled, and large-scale hoisting equipment cannot be used to hoist and speed up the progress, resulting in low efficiency of box culvert construction and high labor costs
