Abstract

The invention relates to the technical field of civil construction and discloses an immersed-tube prefabricated outer wall support which comprises a concrete reaction wall, a fixed reaction frame, a movable reaction frame, a driving device and an outer wall formwork. One end of the fixed reaction frame is vertically arranged on a vertical wall face of the concrete reaction wall, the other end of the fixed reaction frame is connected with one end of the movable reaction frame in a rotatable mode, the other end of the movable reaction frame is used for abutting against the inner side of the outer wall formwork, and the driving device is used for driving the movable reaction frame to stretch out and draw back. The immersed-tube prefabricated outer wall support is stable and reliable in structure, can prevent the outer wall formwork from deforming and swelling, avoids split screws and avoids the water leakage risk of screw channels.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to an immersed tube prefabricated exterior wall support. Background technique [0002] Along with the rapid development trend of super large bridge construction in the world, its construction scope has developed from traditional rivers to sea, especially open sea. In order to solve the huge risks to construction safety and quality caused by harsh weather conditions in offshore construction, and to speed up construction, the concept of large-scale, assembly, and factory-like construction has been widely promoted, and large-scale immersed tube prefabricated components are becoming more and more popular. In the existing prefabrication of bridge construction, the steel formwork used is mainly to fix the outer formwork and the inner formwork by pulling the screw rod, so as to achieve the effect of fixing the outer wall formwork. [0003] The existing steel externa...
