After the direct buried cable trench is dug, a sand cushion layer is laid at the bottom of the trench, and debris in the trench is cleared before laying the cable. However, during the cable pulling process, the laid sand layer is easily damaged and separated. Pulling the cable for a long time causes the cable to connect with the bottom of the cable trench, which not only causes the laid sand layer to lose its protective effect, but also causes the cable surface to be damaged by friction.
