Rowed pile box culvert structure and construction method thereof

Abstract

The invention discloses a rowed pile box culvert structure and a construction method thereof. The rowed pile box culvert structure comprises side column rowed piles, high pressure jet grouting piles, side crown beams, U-shaped base plates and top plates, wherein the side column rowed piles are divided into two groups and are symmetrically distributed on two sides, high pressure jet grouting piles are arranged between two side column rowed piles on each side to form a water stopping curtain, the number of the side crown beams is two, the side crown beams are located above the two groups of side column rowed piles, the U-shaped base plates are cast between the groups of side column rowed piles, side walls of the U-shaped base plates are connected with the inner walls of the side column rowed piles, and the upper portions of the side column rowed piles are cast with the top plates integrally. The construction method of the structure comprises the steps that the row piles are supported, then the base plates and the top plates are cast by adopting inverse excavation construction, construction links are decreased, an original temporary structure for rowed pile supporting is changed into a perpetual structure, engineering structure waste is avoided, a constriction period is effectively shortened, and construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of traffic and water conservancy engineering, in particular to a special box culvert structure and a construction method thereof. Background technique [0002] Box culvert is a kind of culvert, which is generally used for drainage, passing people and vehicles. Box culverts are divided into single-hole box culverts and multi-hole box culverts according to needs. Such as figure 1 As shown, the existing single-hole box culvert is a closed frame structure, and its main components include reinforced concrete culvert body 1', wing wall 2', concrete foundation 3', deformation joint 4' and so on. Such as figure 2 As shown, the existing porous box culvert and figure 1 The single-hole box culvert structure is similar to that in which multiple culverts are arranged on the concrete culvert body 1', and vertical walls 5' are arranged between the culverts. The construction of box culverts generally adopts cast-in-pl...

AI Technical Summary

Problems solved by technology

The foundation pit row pile support of the box culvert structure is a temporary structure with high cost, and the box culvert is abandoned after pouring

And this structure is not suitable for use on ultra-thick soft foundations. If the soft foundation is too thick, the problem of uneven settlement at the bottom of the box culvert will easily occur.
