A Tunnel Waterproof Drainage, Moistureproof and Fireproof Cable Trench System

Abstract

A tunnel waterproof drainage, moisture-proof and fireproof cable trench system, including a cable trench waterproof cover module arranged on the top of the cable trench, a cable trench water monitoring module and a cable trench waterproof wall structure module are arranged in the cable trench, and the cable trench waterproof wall The body structure module is provided with a cable moisture-proof module; wherein, the cable trench waterproof cover module includes several cable trench waterproof covers, waterproof cover anti-skid blocks and waterproof cover water blocking strips; several cable trench waterproof covers are arranged obliquely On the top of the cable trench, the anti-skid block of the waterproof cover is set at the bottom of the waterproof cover, and the waterproof cover is provided with a water blocking strip at the overlap between the adjacent cable trench waterproof covers. The invention can effectively prevent groundwater from affecting the normal operation of the cable pipeline in the cable trench, effectively protect the cable and the overall structure of the cable trench, and improve the service cycle of the cable trench.

Description

technical field [0001] The invention belongs to the field of tunnels and underground engineering, and particularly relates to a tunnel water-proof, moisture-proof and fire-proof cable trench system. Background technique [0002] With the successful convening of the 19th National Congress of the Communist Party of China, the country's requirements for the service level of transportation infrastructure have been further improved, and it is bound to vigorously develop transportation infrastructure. Tunnels, as traffic infrastructure road control projects, do not fully consider the actual conditions of the tunnel site in the design and construction, and often there are serious cases of water leakage from the lining immediately after the completion of many projects, threatening the life and property safety of road users. In the actual operation process, there are the following problems: the seepage water flows into the cable trench along the side wall, posing a threat to the powe...

AI Technical Summary

Problems solved by technology

In the actual operation process, there are the following problems: seepage water flows into the cable trench along the side wall, posing a threat to the power supply line in the cable trench, causing the accumulated water in the cable trench to freeze in a low temperature environment and generate frost heaving force, which has a negative impact on the tunnel. The structure causes irreparable damage; the humidity in the cable trench is high and the temperature is high, and the moisture in the cable trench cannot be discharged in time, which affects the normal operation of the cable pipeline in the cable trench; the cable pipeline is short-circuited due to moisture or the cable joint or cable The temperature of the wire itself rises to cause a fire phenomenon
