Problems solved by technology
However, none of the above methods can fully satisfy the construction work in a narrow space. When laying a large cross-section power cable in a narrow space environment, the cable laying machine cannot be used due to volume limitations, and there are inconsistent or even incapable artificial force during manual laying. Disadvantages, if traditional rollers and manpower are used to lay large-section cables, it will be time-consuming and laborious, the cost is high, and it cannot meet the requirements of construction safety and construction period

The invention discloses an installation structure and a construction method for laying cables in a narrow space. The installation structure includes a rolling hoisting device, a guiding device and a traction device. The guiding device is arranged at the starting point and the corner of the tunnel cable laying path, and the pulling device is arranged at the end point of the tunnel cable laying path. The invention adopts the cable laying structure composed of the rolling hoisting device and the guiding device, which can effectively improve the cable laying quality and efficiency in a narrow space, reduce manual use, effectively reduce the construction cost and construction period, and improve the overall construction efficiency.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an installation structure and construction method for laying cables in a narrow space. Background technique [0002] At present, the domestic cable laying methods are as follows: one is to lay cables in the cable trench directly buried on the ground and in the cable trench with a cover plate; the other is the most used one in electromechanical installation. Lay the cable on. Cables are laid on the ground and in cement cable trenches, usually by winches and rollers or by using cable laying machines. However, none of the above methods can fully satisfy the construction work in a narrow space. When laying a large cross-section power cable in a narrow space environment, the cable laying machine cannot be used due to volume limitations, and there are inconsistent or even incapable artificial force during manual laying. Disadvantages, if traditional rollers and manpower...
