Integrally-mounted bridge cable laying method

Abstract

The invention relates to an integrally-mounted bridge cable laying method. The method comprises the following steps: 1, hoisting and segmenting are carried out on a bridge by applying a pipeline comprehensive technology; 2, holes are formed in the corresponding positions of a top plate, and expansion bolts are installed; 3, connecting, segmenting and straightening of the bridge on the ground are carried out; 4, cable protection riding wheels are installed at the tail ends of the two sides of the head segment, a cable sliding supporting device is laid in the hoisting secondary segment bridge, and a cable horizontal laying restraining device is installed at the turning position; 5, cable laying is carried out, except formal cable fixing at the head segment of the hoisting, other segments alladopt cable temporary fixing devices; 6, the cable protection riding wheels, the sliding supporting device, a temporary restraining device, the temporary fixing devices and the like are disassembledand displacement installation work is completed; and 7, installation of the cable bridge of the vertical part at the tail end of the equipment is completed finally. The overall is enhanced after laying of the cable bridge and the cable on the ground, and the labor cost of cable laying and the aerial work risk are reduced.

Description

technical field [0001] The invention relates to a cable laying method of a self-contained bridge. Background technique [0002] Installation and construction of traditional cable trays and cable laying: take holes on the structural surface or weld bridge columns, install suspension bars or brackets; install bridges and horizontal cross arms, and adjust them as a whole; hand over the air ducts and water pipes at the lower part of the bridge to other professional construction and other related pipelines; lay cables in the bridge frame, and arrange, bind and fix the cables in the bridge frame after laying. [0003] In the traditional construction method, the drilling of the structural surface, the installation of the bridge frame, and the laying of cables are all high-altitude operations, and the installation of the bridge frame and cable laying must be reserved for other professional installation time. Collision displacement, secondary pollution, etc. The cable laying is com...

Problems solved by technology

[0003] In the traditional construction method, the drilling of the structural surface, the installation of the bridge frame, and the laying of cables are all high-altitude operations, and the installation of the bridge frame and cable laying must be reserved for other professional installation time. Collision displacement, secondary pollution, etc.

Cable laying is completed at high altitude, and the operating space of operators in some areas is severely limited, the working environment is harsh, safety accidents are prone to occur, and construction quality is difficult to guarantee
