Temporary construction trestle suitable for mucky area and construction method

Abstract

The invention discloses a temporary construction trestle suitable for a sludge area and a construction method, the temporary construction trestle comprises an upper structure and a lower structure of a bridge deck system, and the lower structure comprises a connecting assembly, a buoyancy box and a plurality of positioning assemblies; the connecting assembly is used for connecting the bridge deck system superstructure and the buoyancy tank; the positioning assembly is formed by connecting a positioning pile and an uplift pile which is provided with a tip end and is provided with a barb-shaped structure on a pile body; the buoyancy box is of a closed box structure which floats on the water surface when not injected with water and sinks after being injected with water. The buoyancy box is provided with a water inlet hole, a water outlet hole and a channel for the positioning assembly to penetrate through; each positioning assembly penetrates through a corresponding channel on the buoyancy tank so as to be connected with the buoyancy tank; after water is injected, the buoyancy box sinks, the positioning assembly is driven to sink, and the uplift pile is inserted into sludge. The temporary construction trestle is suitable for sludge areas, the construction process is simpler, and the construction cost is lower.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a temporary construction trestle bridge and a construction method suitable for a silty area. Background technique [0002] As my country's infrastructure development is getting faster and faster, the development of bridge construction is also accelerating. In bridge construction, it is usually necessary to build a construction trestle parallel to the axis of the main bridge before the main construction, for the passage of personnel and the transportation of construction facilities during construction. The construction of bridges in deep-water silty areas often faces more difficult technical requirements, and traditional construction of trestle bridges will waste more manpower and material resources. At present, trestle bridges on water usually use sinking steel pipe piles as the substructure, and the load-bearing beams of the upper structure use assembl...

AI Technical Summary

Problems solved by technology

In the muddy area, the traditional method is used to build the trestle bridge. The substructure is greatly affected by the muddy quality. It often takes a long time and a lot of materials to build, which is difficult and expensive.
