Box culvert slip form construction device and method

Abstract

The invention discloses a box culvert slip form construction device and method. The box culvert slip form construction device comprises an outer mold, an inner mold and a full support; the outer mold is pulled by an outer mold traction system to slide on tracks; and the integral structure formed by the inner mold and the full support slides under traction of an inner mold traction system. During use, a foundation and a culvert body are firstly constructed, then, the integral structure formed by the full support and the inner mold is pulled and made to slide in place, and the position of the inner mold is adjusted to complete installing of the inner mold; then, the outer mold is made to slide in place, and installing of the outer mold is completed; wall body and culvert cover concrete is poured between the outer mold and the inner mold; and finally, demolding of the inner mold and the outer mold is performed, and the integral structure formed by the inner mold and the full support and the outer mold are made to slide to a next segment of box culvert to take their positions. By means of the box culvert slip form construction device and method, the integral structure formed by the inner mold and the full support can slide and the outer mold can slide as a whole, repeated installing of a formwork and a support is avoided, operation is quite easy, the workload for installing and detaching the formwork is reduced, the mechanical degree is high, the construction speed is high, and the construction period is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of culvert construction, in particular to a construction device and method for a highway box culvert sliding form. Background technique [0002] Culverts are an important part of roadbed construction, and are mainly used to quickly remove surface water along the road to ensure roadbed safety. Box culvert is a type of culvert that is widely used. It refers to the culvert built with reinforced concrete box-shaped pipe joints. The box culvert can include one or more joints. The cross-section of each joint is square or rectangular. Generally, it is composed of Reinforced concrete or masonry, among them, reinforced concrete is widely used. The cover, body and foundation of the box culvert are integrated with reinforced concrete, which can be used for drainage, passage of people and vehicles.

Problems solved by technology

[0003] In the prior art, the main construction method of the box culvert is the full house support method, but this method needs to repeatedly set up and disassemble the support and formwork, and there are many procedures, time-consuming, labor-intensive, and low work efficiency, especially for long-distance, For box culvert construction with a tight schedule, it often cannot meet the construction needs
