Bridge construction method

Abstract

The invention discloses a bridge construction method. According to the bridge construction method, the problems that the construction quality is poor, and the construction period is delayed are solved. According to the technical scheme, the bridge construction method comprises the steps of pier column construction, specifically, a forming template is assembled on a construction site, steel bars are fixedly installed, and concrete layered pouring is conducted; hollow plate construction, specifically, hollow plates are prepared according to needs, and prestress test and construction error analyzing and controlling are conducted; hollow plate hoisting, specifically, the position and height of hoisting are in accordance with the designed position and height; scaffold erecting, specifically, ascaffold is corrected continuously in the erecting process to make the scaffold meet requirements; high-formwork construction, specifically, a bracket is installed, a beam template is installed, and afloor template is installed; and concrete construction, specifically, qualification testing of raw materials is conducted firstly, the raw materials are mixed according to proportion after being qualified, and then layered pouring and continuous pouring are conducted. The project is divided into different construction projects, during construction, the different construction projects or the previous preparation of construction are implemented on different construction sites and can be started and conducted simultaneously at a proper time, and workers are deployed reasonably, so that the construction efficiency is improved advantageously.

Description

technical field [0001] The invention relates to the field of bridge construction, more specifically, it relates to a bridge construction method. Background technique [0002] At present, the construction method of the continuous beam of the existing bridge is: the construction of the continuous beam is carried out after the construction of the pier is completed. However, when the bridge is very high and the span is large, the disadvantages of this method are: the construction period of the bridge pier and bridge is long, there is only one working surface, and each process must be constructed in sequence, which seriously restricts the total construction period, and the error is large. It is difficult to guarantee, resulting in repeated construction and further prolonging the construction period. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bridge construction method, which has the adva...
