Abstract

The invention discloses a back-up wall simple support structure and a construction method based on the same. The back-up wall simple support structure comprises an abutment back-up wall, a plurality of steel tubes, a formwork, pre-embedded steel plates, triangular brackets, a square timber, I-beams and formwork brace pieces. The formwork is erected on the abutment back-up wall through the steel tubes, one ends of the I-beams are perpendicularly fixed to the abutment back-up wall, and the pre-embedded steel plates are arranged on the abutment back-up wall and located under the I-beams. One endsof the triangular brackets are fixed to the pre-embedded steel plates, the other ends of the triangular brackets are fixed to the bottoms of the I-beams, and the square timber is arranged on the I-beams. According to the construction method based on the back-up wall simple support structure, the construction progress is speeded up, the labor and mechanical inputs are saved, and the working efficiency is improved.

Description

technical field [0001] The application relates to the technical field of construction engineering, and in particular, to a simple support structure for a back wall and a construction method based on the simple support structure for a back wall. Background technique [0002] In the expansion project of Qingyin Expressway, the first application of liquid fly ash platform back construction technology has made a positive contribution to the improvement of project quality. This leads to severe challenges in the construction period of bridge abutment backs. [0003] In the prior art, when the construction platform is covered with beams, most of the construction is carried out by the full-house support method. This method requires that the bearing capacity of the foundation under the bridge is good, and the handling, erection, dismantling, sand bag preloading, formwork support, etc. of the scaffold are all equal. It can be done manually, so large-scale lifting equipment is not req...
