Problems solved by technology

However, the conveyor is large in size and weight, which makes it inconvenient to operate in the comprehensive pipe gallery. It is usually operated outside the comprehensive pipe gallery. Not only is it inconvenient to use, but also the cable end of the conveyor needs to be pulled and guided by manpower all the time, and the one-time investment is large. Low construction efficiency and high construction cost

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is described further as follows:

[0023] A method for laying cables with large cross-sections, comprising the following steps:

[0024] 1), use the column 2 to lay the cable tray 1 inside the comprehensive pipe gallery;

[0025] 2) Install a cable reel at the starting point of the cable tray 1, and install an electric winch or hoist at the end of the cable tray 1;

[0026] 3), making the roller device, the first type of roller device located at the corner of the cable tray 1 and the second type of roller device located outside the corner of the cable tray 1 and uniformly distributed along the extending direction of the cable tray 1; A type of roller device includes a first roller 41 located above the cable tray 1 and a first bracket, the first roller 41 is detachably mounted on the column 2 at the corner of the cable tray 1 through the first bracket, the first roller 41 Arranged in th...

Abstract

The invention provides a large-section cable laying method, belongs to the field of cable laying, and aims at reducing the cable laying difficulty in a comprehensive tube lane, improving the laying efficiency and reducing the construction cost. The method comprises the following steps: (1) laying a cable bridge in the comprehensive tube lane by an upright post; (2) installing a cable reel at the starting point of the cable bridge, and arranging an electric winching or a winding engine at the end point of the cable bridge; (3) fabricating a roller device; (4) binding the end of a traction wire rope on the electric winching or the winding engine and the end of a cable firmly; (5) starting the electric winching or the winding engine and pulling the cable in place along the laying path; and (6) binding the cable on the cable bridge segment by segment. By the large-section cable laying method, the cable can be pulled to move along the laying path under the action of relatively small traction force; manpower, a hoisting device and the like do not need to be input in the comprehensive tube lane in the overall laying process; the laying difficulty is reduced; the laying efficiency is improved; and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the field of cable laying, in particular to a large-section cable laying method. Background technique [0002] For the interior of the comprehensive pipe gallery, due to the large number of process pipelines, long pipelines, and narrow bridge corridors, cables are usually laid manually or by conveyors in the comprehensive pipe gallery. However, the conveyor is large in size and weight, which makes it inconvenient to operate in the comprehensive pipe gallery. It is usually operated outside the comprehensive pipe gallery. Not only is it inconvenient to use, but also the cable end of the conveyor needs to be pulled and guided by manpower all the time, which requires a large one-time investment. The construction efficiency is low and the construction cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-section cable laying method, which is suitable for...
