Problems solved by technology

However, the spanning height and spanning distance of this structure are relatively limited, and because the bending and compressive resistance of a single member is small, the overall strength and stability of the spanning frame are poor
At the same time, this kind of spanning frame requires more materials and manpower to build, and the transportation workload is large, which takes a long time.
Furthermore, this spanning construction method is only suitable for situations where the road conditions on both sides of the railway are in good condition. If there is no flat ground on one side, this method of artificial erection on both sides cannot be carried out.

Embodiment 1

[0104] In the vicinity of a railway line in a certain place in the south, the construction of cross-construction protective equipment is carried out. The specific steps are as follows:

[0105] 1. After leveling the ground of the area to be constructed, transport the two pieces of equipment to the designated location by the transport vehicle respectively. The two transport vehicles are set on the same side of the rail and parallel to the rail, with a distance of about 18m;

[0106] 2. Operate the outrigger arm cylinders on the two pieces of equipment separately, expand the outrigger arms to the specified angle, lower the outriggers and level the base. After the outrigger moves in place, install the outrigger swing arm fixing rod and outrigger fixing pin.

[0107] 3. Adjust the beam and auxiliary tower

[0108] 3.1 Synchronously start the slewing system of the two equipments, and rotate the slewing frame and the upper equipment at a smaller angle synchronously, forming a hangi...

Abstract

The invention provides a construction method for crossing construction protection equipment and a method for cross-line construction above the protected line. The construction method for crossing theconstruction protection equipment comprises the steps that equipment to be unfolded is fixed; then rotation is carried out, a net hanging space between two adjacent beams is formed, and the beams andan auxiliary tower are adjusted; a protective net is installed between the two adjacent beams; then a main tower is erected; during the blocking time, the beams cross the protected line; the auxiliarytower is lowered to support the beams; and the beams, the main tower and the auxiliary tower are fixed separately. The construction method for crossing the construction protection equipment has simple and convenient steps, no manual erection or manual installation of a pulling rope is required, the construction time is short, and the construction cost is low; and the construction process can be completed in a short blocking time, and the safety of crossing construction can be guaranteed.

Description

technical field [0001] The invention relates to the field of construction of power transmission lines, in particular to a construction method for crossing construction protective equipment and a method for crossing construction above a protected line. Background technique [0002] With the comprehensive construction and operation of domestic railways, it is inevitable that the new power transmission line project will cross the railway construction. In order to ensure the safety of railway operation, according to the relevant regulations of the railway department, corresponding protective operations must be carried out when cross-line construction operations are carried out above the railway, and dangerous operations are only allowed to be performed within the skylight point. [0003] At present, the cross-line construction protection work is to manually build scaffolding on both sides of the railway. After the construction is completed, traction ropes and protective nets are...
