Embodiment Construction

[0036] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0037] As shown in the figure, the application method for laying high-voltage cables under high-drop terrain conditions mainly includes four steps. The first step is to select tractor 1, conveyor 2, roller 3 and power supply according to the terrain of the construction site and the general situation of the project. In other words, according to the situation of the laying line 5, including the levelness of the hoistway, the angle of the corner or the inclination angle of the slope, and the cable type, etc., select the tractor 1 with the appropriate power, the conveyor 2 with the appropriate power and quantity, and the roller 3 with the appropriate number, etc. .

[0038] The second step, according to the situation of the laying line 5, mainly refers to arranging the selected auxiliary tools according to the horizontality of the hoistway, the angle of rotation ...

Abstract

The invention discloses a high-voltage cable laying and optimization method under a high-fall terrain condition, and the method mainly comprises the steps: selecting and arranging a traction machine,a conveyor and rollers, arranging the traction machine at the tail end of a laying line, uniformly distributing the conveyor at a straight line segment of the laying line, and arranging a roller groupat a corner part of the laying line, wherein the idler wheel set comprises at least two idler wheels, the idler wheels in the idler wheel set are distributed in an arc-shaped array mode and matched with the angle of the corner portion, then a traction machine is used for traction to complete laying, and the optimization method mainly adopts a simulation analysis method to optimize the arrangementmode and tool parameters. By adopting the scheme, the construction difficulty is lowered, the cable laying efficiency under complex terrain conditions is improved, economic benefits are reasonably controlled, cable laying damage is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to a high-voltage cable laying under high-drop terrain conditions and an optimization method thereof. Background technique [0002] In urban municipal construction, high-voltage cables are generally buried in the ground. For cities with complex terrain such as Chongqing, the space for buried high-voltage cables is greatly squeezed due to the shortage of underground passage resources, and the terrain design of cable tunnels is becoming more and more complicated. Dense, crowded passages, deep tunnels and steep slopes, etc., in engineering practice, there are generally complex terrains such as deep shafts and long slopes, and the construction is very difficult. [0003] For this type of complex terrain with deep shafts and long slopes, during cable laying construction, due to the heavy weight of the cable in the shaft section, the cable will bear a large lateral pressure at the tu...
