Construction method of cast-in-place pier of municipal viaduct

Abstract

According to the construction method of the cast-in-place pier of the municipal viaduct, the mode of hoisting an inner box is adopted to be matched with a hydraulic self-climbing formwork mechanism to conduct construction of a pier body, the inner box is automatically demolded in the hoisting process, and constructors can tension an outer formwork and the inner box on a scaffold of the hydraulic self-climbing formwork mechanism through opposite-pulling components; constructors do not need to enter the pier body for construction, so that the construction efficiency of the pier body is remarkably improved, and the construction period of the pier is remarkably shortened.

Description

technical field [0001] The present application relates to the technical field of bridge pier construction, in particular to a construction method for cast-in-place bridge piers of municipal viaducts. Background technique [0002] The structure at the bottom of the bridge that supports the bridge is usually a bridge pier. A bridge pier generally includes a pier base, a pier body and a top cap. For some viaducts, the height of the pier is as high as tens of meters. In order to reduce the weight of the pier, the pier body is often designed with a hollow structure. [0003] With the development of science and technology, the current high bridge piers are generally constructed in sections by means of hydraulic self-climbing formwork mechanisms during construction. During construction, after the workers complete the construction of the pier at the construction site, they arrange the steel skeleton on the pier according to the design thickness of the pier, then install the hydrau...

Problems solved by technology

However, as the height of the pier body increases, scaffolding needs to be continuously built inside the pier body, which seriously affects the construction efficiency of the pier body
