A method for synchronous construction of car ramp and floor structure in reverse construction

Abstract

The invention discloses a method for synchronously constructing vehicle slopes and floor structures in reverse construction. The method comprises the following steps: (1) a floor B0 and a floor B1 of a basement structure are constructed in sequence; and temporary supports are arranged on a top plate according to the stress demands; (2) a lower-layer earthwork is excavated; and meanwhile, a vehicle slope on the floor is constructed in the floor B1 structure; (3) the steps (1) to (2) are repeated until a vehicle slope from a floor Bn-1 to a floor Bn-2 is constructed; and (4) a basement baseplate is constructed; and then, a vehicle slope on a bottommost floor of the basement structure is constructed. The method for synchronously constructing the vehicle slopes and the floor structures in reverse operation solves the difficulty that the basement structure is difficult to synchronously construct with side walls of the vehicle slopes in reverse construction, realizes synchronous reverse construction of the vehicle slopes and the basement structure, is early in forming time of the vehicle slopes, is easy to guarantee the progress, and prevents such difficulties as support replacement, drilling away of support beams and outward conveying of waste concrete caused by reverse construction of the basement and forward construction of the slopes through conventional methods.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for synchronous construction of a car ramp and a floor structure in reverse operation. Background technique [0002] With the rapid development of large-scale deep foundation pit engineering, more and more applications of reverse method construction. In the traditional upside-down construction, the concrete walls on both sides of the car ramp are difficult to be constructed simultaneously with the basement structure. Therefore, the conventional method of the car ramp is to complete the basement structure first and then build the car ramp along the way. The overall construction of the car ramp is completed. The time is often too late to meet the large amount of material transportation needs for the construction of masonry projects, installation projects, rough decoration projects and fine decoration projects in the basement. At the same time, in the implementation pr...

Problems solved by technology

In the traditional upside-down construction, the concrete walls on both sides of the car ramp are difficult to be constructed simultaneously with the basement structure. Therefore, the conventional method of the car ramp is to complete the basement structure first and then build the car ramp along the way. The overall construction of the car ramp is completed. The time is often late, which cannot meet the large amount of material transportation needs for the construction of masonry works, installation works, rough decoration works and fine decoration works in the basement

At the same time, in the implementation process of the conventional method, it is necessary to construct the car ramp while removing the support, the construction speed is extremely slow, and the secondary deformation is large; and it is difficult to apply the temporary support to the car ramp structure, and it must be completely removed, resulting in a large waste of materials
