Problems solved by technology

[0004] In order to solve the above problems, the present invention proposes a steel-concrete composite beam lateral flat roof construction structure and method. The present invention adopts steel-concrete composite beams on the small-angle crossing operation line of the viaduct, and sets temporary pier piles on the side of the existing line during construction. For the support pier, the steel-concrete composite beam is firstly constructed above the temporary support pier, and the construction method of using the slideway at the skylight point and placing the lateral flat roof in place can effectively solve the long-term and risky construction above the existing operation line. Large, affecting operations and other issues

Abstract

The invention relates to a lateral flat top construction structure and method for a reinforced concrete superposed beam. The structure comprises a temporary buttress system arranged on the side of a pier column beside an existing line, a sliding way is arranged at the top of the temporary buttress system and on a steel cross beam stretching across the upper portion of the existing line, a reinforced concrete superposed beam is erected on the sliding way on one side of the temporary buttress system firstly, and the reinforced concrete superposed beam is in place through a lateral flat top at the skylight point time. The construction working time of the operation line is greatly reduced, the interference of the construction process to the existing operation line under the bridge is minimum,and the construction cost is economical and safest.

Description

technical field [0001] The invention relates to a construction structure, in particular to a steel-concrete composite beam lateral flat-roof construction structure and a construction method thereof, belonging to the field of rail transit engineering. Background technique [0002] In recent years, with the rapid development of the economy, my country's transportation infrastructure has made great progress. Among them, large cities have vigorously developed urban rail transit projects. Due to the influence of line direction and existing operating lines, rail transit elevated lines need to cross the existing There are structures on operating lines, and the design of the viaduct needs to consider crossing the existing operating lines and the construction cannot affect the operation safety of the existing subway lines. Therefore, it is very necessary to study an economical and safe construction method. [0003] The traditional construction method of steel-concrete composite beam g...
