Prefabricated steel pipe concrete and reinforced concrete bridge piers

Abstract

The invention relates to a prefabricated steel tube concrete and reinforced concrete assembled bridge pier, which includes a pier foundation, a prefabricated steel tube concrete segment, one or more prefabricated reinforced concrete middle segments and a prefabricated reinforced concrete top segment, wherein the pier foundation The prefabricated steel tube concrete segments are fixedly connected to the bottom anchor bolts provided on the pier foundation, and the prefabricated steel tube concrete segments are connected to the precast reinforced concrete intermediate segments and a plurality of precast reinforced concrete sections. The middle segments, the precast reinforced concrete middle segments and the precast reinforced concrete top segments are fixedly connected by means of connecting units. Each component of the invention has a simple structure, which not only facilitates prefabrication in the factory, but also facilitates on-site splicing, thereby increasing the speed of construction operations and effectively reducing the intensity of on-site operations. In addition to high bearing capacity, good compression, bending and shear resistance, and good durability, this assembled bridge pier also has the advantages of good seismic resistance.

Description

technical field [0001] The invention belongs to the field of bridge engineering, and in particular relates to a bridge pier assembled with prefabricated steel pipe concrete and reinforced concrete. Background technique [0002] At present, most of the bridges built in my country are composed of cast-in-place reinforced concrete abutments, cast-in-place concrete piers, cast-in-place concrete bridge decks and precast concrete beams. Cast-in-place concrete construction is time-consuming and requires many on-site construction procedures that negatively affect traffic flow, safety in the work area and the environment, especially in complex construction environments, construction spaces, climatic conditions and environmental protection Conditions and other factors seriously affect the progress of bridge construction. [0003] Research on the connection technology between precast concrete piers and foundations, the connection technology between precast concrete sections, the conne...
