Dehumidification and drainage cable trench

Abstract

The invention provides a dehumidification and drainage cable trench, which includes an inner groove, an outer groove and a cover plate. The inner groove includes a left vertical plate of the inner groove, a right vertical plate of the inner groove and a bottom plate of the inner groove. The left vertical plate, the right vertical plate of the outer tank and the bottom plate of the outer tank form a hollow circuit between the inner tank and the outer tank, and two rows of circular The inner exhaust holes are also provided with two rows of outer exhaust holes at the upper position of the vertical plate on the right side of the outer tank corresponding to the height of the inner exhaust holes; one piece is extended at the edges of both sides of the cover plate. As for the side plate, a drain is opened at the bottom end of the vertical plate on the right side of the outer tank. Beneficial effects are: the design increases the air circulation in the cable trench and effectively removes moisture. The design of the side plate prevents rainwater from entering the cable trench from the vent hole. The outlet will flow out in time, and the cable trench will always be kept dry to ensure the safety of electricity use.

Description

technical field [0001] The invention relates to the field of tunnels and underground engineering, in particular to a dehumidification and drainage cable trench structure. Background technique [0002] The cable trench is an underground special channel for laying cables. It is mostly used for the laying of substations or urban lines. The traditional cable trenches are made of cement. Although the cable trench made of cement has good strength, because it is laid underground, cement The structure is easy to get damp, and when the humidity in the cable well is too high, the cable will be corroded, resulting in short circuit and other adverse conditions, increasing safety hazards, affecting normal power consumption, and greatly affecting the supply of users. Contents of the invention [0003] The purpose of the present invention is to provide a dehumidification and drainage cable trench, which can effectively solve the problem of ventilation and dehumidification in the cable tr...
