Multi-point floor type steel frame protection method for bridge structure adjacent to high tension line

Abstract

The invention relates to a multi-point floor type steel frame protection construction method for a bridge structure adjacent to high tension line. The method comprises the following steps that a slideway for allowing a protection steel frame to move and a supporting foundation are arranged around a specified position around a bridge adjacent to the high tension line, and the protection steel frame is built and constructed at the same time; and a numerical control hydraulic pushing technology is adopted for pushing and transferring the protection steel frame for two times, the protection steelframe is pushed and transferred to the side of the bridge site of the bridge adjacent to the high tension line by the first time, and orbital transfer is carried out for pushing and transferring theprotection steel frame to the slide way by the second time, so that the protection steel frame is pushed to cover the bridge adjacent to the high tension line for protection. According to the multi-point floor type steel frame protection construction method for the bridge structure adjacent to the high tension line, the construction cost can be reduced, the construction progress is accelerated, the working efficiency is improved, the bridge construction safety is guaranteed, and the problem that the bridge structure adjacent to the high tension line cannot be constructed without changed move treatment is solved.

Description

technical field [0001] The invention relates to bridge protection, more specifically, to a method for protecting a multi-point floor-type steel frame of a bridge structure adjacent to a high-voltage line. Background technique [0002] With the rapid development of national infrastructure construction, bridge structures are widely used in projects such as high-speed railways, highways, and urban rails. The construction environment of bridge structures is complex and changeable, which limits construction and puts forward higher requirements for construction technology, especially When the bridge structure is constructed near the high-voltage line, there are clear distance requirements, and it is difficult to approve the power relocation plan. For the protection of the bridge structure near the high-voltage line, there is a problem that the bridge structure cannot be constructed without relocation.
