Embodiment Construction

[0051] The following is attached Figure 1-7 The application is described in further detail.

[0052] The embodiment of the present application discloses a direct buried cable laying method, including the following steps:

[0053] Step S1: According to the site conditions and calculation analysis, plan the cable route, and excavate the trench 2 on the surface of the ground layer 1;

[0054] Step S2: Lay the gravel cushion 3 on the bottom wall of the trench 2 and the trench walls on both sides, and pour a concrete waterproof plastering layer 4 on the surface of the gravel cushion 3, which will not affect the watering and maintenance of the poured concrete After less than 7 hours, the cable trench 5 is formed;

[0055] Step S3: According to the planned cable route, several drainage boxes 6 are sequentially installed on the bottom wall of the cable trench 5, and the length direction of the drainage boxes 6 is placed in line with the length direction of the cable trench 5. A st...

Abstract

The invention relates to a directly-buried cable laying method which comprises the following steps of S1, planning a cable path, and digging a groove in the surface of a ground layer; S2, laying broken stone hardcore layers on the trench bottom wall and two side trench walls of a trench, and pouring concrete waterproof plaster layers on the surfaces of the broken stone hardcore layers to form a cable trench; S3, installing a plurality of drainage boxes on the trench bottom wall of the cable trench, defining a water storage and drainage space by the side walls of the drainage boxes and the trench wall of the cable trench, and enabling water in the water storage and drainage space to permeate into the drainage boxes through water seepage holes in the side walls of the drainage boxes to be collected; S4, along the planned cable path, dragging the cable to the top of the drainage box and fixing; S5, covering a cement cover plate above the cable trench along the planned cable path until thecable trench is closed; and S6, backfilling the cable trench, and completing the laying of the directly-buried cable. The method has the effect of preventing the cable from being soaked in rainwaterfor a long time to affect the service life.

Description

technical field [0001] The present application relates to the field of cable laying, in particular to a direct buried cable laying method. Background technique [0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application occasion, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. The choice of cable laying method is very important to ensure the transmission quality, reliability and construction maintenance of the line. [0003] The direct buried cable is in accordance with the requirements of the specification. After the direct buried cable trench is dug, a sand cushion is laid on the bottom of the trench, and the sundries in the trench are removed, and then the cable is laid. A cable laying method in which a layer of bricks or concrete slabs are covered on the cable to protect the cable, and then bac...
