Construction device and construction method for long-distance and large-diameter cable laying in cable trench

Abstract

The invention relates to a construction device for long-distance and large-diameter cable laying in a cable trough, including a walking lifting device. The walking lifting device is provided with a lifting frame, and a flexible bottom bearing is detachably installed on the lifting frame. bracket. The invention also discloses a long-distance and large-diameter cable laying construction method in the cable trench. The invention has the following beneficial effects: firstly, a cable trench is drilled on the ground with a ditching tool, and cables are laid on the side of the cable trench along the length direction of the cable trench. It is easier to lay the cables on the side of the cable trench Realize mechanized operation, and then transfer the cables to the cable trench through the long-distance and large-diameter cable laying construction device in the above-mentioned cable trench, and then backfill the cable trench with soil, which reduces the required labor force and greatly reduces the labor intensity. The safety is improved, the operation method is simple and easy to implement, easy to popularize, and can generate greater economic benefits.

Description

technical field [0001] The invention relates to a long-distance and large-diameter cable laying construction device and construction method in a cable trench, belonging to the technical field of cable construction. Background technique [0002] The laying of power cables in thermal power plants mainly includes power distribution room to major rotating machinery such as fans, coal mills, feed water pumps, circulating water pumps and corresponding MCC cabinets. The types of power cables mainly include: flame-retardant high-voltage power cables, fire-resistant low-voltage power cables, flame-retardant low-voltage power cables, etc. Since most of the power distribution room and various electrical equipment are connected through cable trenches, coupled with the large diameter of the power cable itself, heavy weight per unit length, and long laying distance for a single cable, the construction efficiency of purely manual laying, especially in the cable trench, is extremely low. ,...

AI Technical Summary

Problems solved by technology

Since most of the power distribution room and various electrical equipment are connected through cable trenches, coupled with the large diameter of the power cable itself, heavy weight per unit length, and long laying distance for a single cable, the construction efficiency of purely manual laying, especially in the cable trench, is extremely low. , if all manual laying has the disadvantages of high physical labor intensity and high cost, and it is difficult to achieve consistency in action when there are many construction personnel, the construction organization is relatively difficult, and the quality and safety of cable laying are difficult to guarantee. How to improve the performance of large-diameter cables Laying construction efficiency and laying quality have always been the focus of cable laying construction
