a cable trench

Abstract

The invention relates to a cable trench, which includes a trench body and a plurality of cover plates covering the trench body, the trench body is a cuboid trench structure, and the cover plate includes a top plate, an outer sealing plate integrally connected The two inner sealing plates on the bottom of the roof, the inner sealing plate and the outer sealing plate are perpendicular to the top plate, and the inner sealing plate and the adjacent outer sealing plate can clamp the side wall of the ditch between them; The bottom of the body is provided with a drainage device, and the drainage device includes an outer sleeve, a drain pipe and a self-sealing assembly that is rotated at the drain end of the drain pipe; one end of the outer sleeve is fixedly connected to the bottom surface of the ditch body, and the other end is connected to the water collection device; the drain pipe sleeve It is arranged in the outer casing, and one end is fixed on the bottom surface of the ditch body and communicated with the ditch body, and the other end extends into the outer casing; the cable ditch of the present invention can better prevent rainwater and snow water from penetrating into the ditch body, and can realize water accumulation in the ditch body The automatic discharge saves manpower and reduces the potential safety hazard caused by water accumulation in the ditch.

Description

technical field [0001] The invention relates to the technical field of cable construction engineering, in particular to a cable trench. Background technique [0002] With the progress of the society and the continuous development of the economy, people's requirements for communication are constantly improving, but the old-fashioned high-altitude pull net has many defects, which speeds up the construction of underground cable communication facilities. Most of the underground cables at this stage are arranged in pre-dug cable trenches. [0003] Such as figure 1 As shown, the traditional cable trench mainly includes a trench body 101 and a cover body 102. The trench body 101 is a cuboid groove structure with an opening on the top surface, and the cover body 102 is a rectangular plate structure. The cover body 102 can be covered on the trench body. 101 top, the top surface of ditch body 101 is sealed; On the vertical inner wall of ditch body 101, weld or fix upper support 103 ...
