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...

The present application relates to a direct buried cable laying method, which includes the following steps: Step S1: plan the cable route, and excavate a trench on the surface of the ground layer; For the stone cushion layer, a concrete waterproof plastering layer is poured on the surface of the crushed stone cushion layer to form a cable trench; Step S3: Install several drainage boxes on the bottom wall of the cable trench, and the side wall of the drainage box and the trench wall of the cable trench Enclosing and forming a storage and drainage space, the water in the storage and drainage space seeps into the interior of the drainage box through the seepage holes on the side wall of the drainage box for collection; Step S4: along the planned cable path, pull the cable to the top of the drainage box and fix it; Step S5: Along the planned cable path, build a cement cover plate above the cable trench until the cable trench is closed; Step S6: Backfill the cable trench to complete the direct buried cable laying. The application has the effect of preventing the cables from being soaked in rainwater for a long time and affecting 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...
