Waterproof-drainage, moistureproof and fireproof cable trench system for tunnel

Abstract

The invention discloses a waterproof-drainage, moistureproof and fireproof cable trench system for a tunnel. The waterproof-drainage, moistureproof and fireproof cable trench system comprises a waterproof cover plate module of a cable trench arranged at the top of the cable trench, a cable trench water monitoring module arranged in the cable trench, and a waterproof wall structure module of the cable trench, wherein the waterproof wall structure module of the cable trench is provided with a cable moistureproof module, wherein the waterproof cover plate module of the cable trench comprises a plurality of waterproof cover plates of the cable trench, anti-skid stop blocks of the waterproof cover plates and waterproof cover plate water-blocking strips; the plurality of waterproof cover platesof the cable trench are obliquely arranged at the top of the cable trench; the anti-skid stop blocks of the waterproof cover plates are arranged at the bottoms of the waterproof cover plates separately; and one waterproof cover plate water-blocking strip is arranged at the joint between two adjacent waterproof cover plates of the cable trench. According to the waterproof-drainage, moistureproof and fireproof cable trench system for the tunnel, underground water can be effectively prevented from affecting normal working of a cable pipe in the cable trench, the overall structure of a cable and the cable trench is effectively protected and the service period of the cable trench is prolonged.

Description

technical field [0001] The invention belongs to the field of tunnels and underground engineering, and in particular relates to a drainage, moisture-proof and fire-proof cable trench system for tunnels. Background technique [0002] The country's requirements for the service level of transportation infrastructure are further improved, and it is bound to vigorously develop transportation infrastructure. Tunnels are traffic infrastructure and road control projects. Since the actual conditions of the tunnel site area are not fully considered in design and construction, there are often serious cases of lining water leakage immediately after the completion of many projects, threatening the lives and properties of road users. 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...

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
