Cable trench drainage device and construction method thereof

Abstract

The invention discloses a cable trench drainage device and a construction method thereof. The cable trench drainage device and the construction method thereof aim to solve the field drainage problem of a closed area enclosed by a cable trench and a building in the prior art. The construction method thereof comprises the steps that a PVC drainage pipe is embedded before cable trench concrete is poured, and the two sides of the cable trench communicate; then the e trench concrete is poured, and reliable connection of the PVC drainage pipe and the wall of the trench is guaranteed; a cover plate is laid, cement mortar is applied at the connecting position of the PVC drainage pipe and the cover plate, and surface flatness is guaranteed; and plain concrete is poured on sites on the two sides of the PVC drainage pipe, a certain gradient is set in the plain concrete and an original ground area, water flows to the site on the opposite side from the closed area through the PVC drainage pipe, and facilities such as a catch basin are arranged on the site on the opposite side to drain the water.

Description

Technical field [0001] The present invention relates to a cable trench drainage device and a mechanical method thereof, belonging to the field of booming station. Background technique [0002] The cable is a channel-layered channel in the boost station area, and the top surface of the cable trench is generally higher than the ground. There is a partial venue near the building and the cable ditch, which is around the cable, the building, and the rainwater inside the region cannot be discharged through natural discharge. If it is not treated, it is sufficient when the rain is sufficient. It is possible to cause a large amount of rainwater, mud flow into the cable, and even in the indoor cable ditch of the distribution room when the flow rate is large, the normal operation of the electrical equipment of the boost station is adversely affected. At the same time, the cable itself allows some rainwater to enter, but only a small amount of rain is allowed to enter the rain. Therefore, t...

AI Technical Summary

Problems solved by technology

There are some sites near buildings and cable trenches, which are surrounded by cable trenches and buildings to form a closed area. The rainwater in this area cannot be discharged through natural drainage; if no treatment is carried out, when the rainwater is sufficient It may cause a large amount of rainwater and mud to flow into the cable trench on the site, and even flow back into the indoor cable trench of the power distribution room when the flow is large, which will adversely affect the normal operation of the electrical equipment of the booster station

At the same time, although the cable trench itself allows some rainwater to enter, it only allows a small amount of rainwater not mixed with mud to enter.
