A cable tunnel multifunctional inspection shaft

Abstract

The invention discloses a multifunctional cable tunnel inspection well. An intelligent sewage discharge control box is installed on one side of a house wall on the upper portion of the inspection well. A switch door is arranged on the road facing face of the portion, located on the upper portion of the inspection well, of a house. A solar cell panel is installed at the top of the portion, located on the upper portion of the inspection well, of the house. An accumulator is installed on the portion, located on the upper portion of the inspection well, in the house and connected with the solar cell panel. A lamp is installed at the top of the portion, located on the upper portion of the inspection well, of the house. Rainproof shutters are installed on three faces of the portions, located on the upper portion of the inspection well, of the house and protective nets are installed on the shutters. A galvanized safety cover board is installed on the upper portion of a water collection pit. A crawling ladder is located on the lower portion of the inspection well. A cable support is located in a cable trench and extends to the lower portion of the inspection well. The water collection pit is located on the lower portion of the inspection well. A liquid level meter is located in the water collection pit. A submersible sewage pump is located in the water collection pit. A flexible waterproof casing pipe is located on a wall penetrating portion of a water drainage pipe. The water drainage pipe is connected with the submersible sewage pump and connected to an external water drainage inspection well. The multifunctional cable tunnel inspection well is easy to install, convenient to maintain, attractive in appearance, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to the field of cable tunnels, in particular to a multifunctional inspection shaft for cable tunnels. Background technique [0002] Existing cable trenches and cable tunnels are generally only equipped with inspection openings or safety holes for personnel maintenance, and the distance between safety holes in tunnels in industrial factories or substations should not be greater than 75m. If effective ventilation facilities are not installed, the air in the ditch will be dirty, which will affect the life safety of maintenance personnel. Drainage slopes or diversion grooves are set at the bottom of the ditch, and after being collected into the sump, they are discharged to the nearest drainage inspection well through PVC pipes. Due to the depth of the cable tunnel (cable trench) plus the depth of the sump, it is generally deeper than the depth of the drainage pipe network. Low, can not be effectively natural drainage or even backflow...

Problems solved by technology

[0002] Existing cable trenches and cable tunnels are generally only equipped with inspection openings or safety holes for personnel maintenance, and the distance between safety holes in tunnels in industrial factories or substations should not be greater than 75m

If effective ventilation facilities are not installed, the air in the ditch will be dirty, which will affect the life safety of maintenance personnel

Drainage slopes or diversion grooves are set at the bottom of the ditch, and after being collected into the sump, they are discharged to the nearest drainage inspection well through PVC pipes. Due to the depth of the cable tunnel (cable trench) plus the depth of the sump, it is generally deeper than the depth of the drainage pipe network. Low, unable to effectively drain naturally or even pour back, resulting in a large amount of water in the cable tunnel (cable trench)

The cable trench is not equipped with lighting facilities, which is inconvenient for maintenance
