Abstract

The invention discloses a waterproof system of an urban tunnel structure, and belongs to the field of urban underground passages. A waterproof system of an urban tunnel structure comprises a water storage tank, the water storage tank is formed in a roadbed provided with an underground channel, water guiding grooves are formed in the two sides of the underground channel and communicate with the water storage tank through water through holes, a first water suction pump is fixedly connected into the water storage tank, and a second water suction pump is fixedly connected into the first water suction pump. The water pumping end of the first water pump is connected with a water pumping pipe, the water pumping pipe is located in the water storage tank, and the water outlet end of the first water pump is connected with a water outlet pipe; accumulated water above the lifting plate is pumped out through the first water pump by means of the water pumping pipe and then conveyed into a sewer line of a city through the water outlet pipe, water accumulation is avoided, when the water accumulation amount is too large, the lifting plate presses the gas storage bag downwards, the gas release valve is instantly opened, the gas storage bag becomes flat, at the moment, the lifting plate rapidly moves downwards, the water storage space is increased, and the water storage effect is improved. The safety is ensured.

Description

technical field [0001] The invention relates to the technical field of urban underground passages, in particular to a waterproof system for urban tunnel structures. Background technique [0002] With the rapid development of the city, there are more and more private vehicles, and at the same time, it brings great challenges to the city's roads, and often encounters traffic jams. A variety of viaducts or underground passages are used to realize a three-dimensional road passage that is fully interconnected from top to bottom, avoiding traffic jams caused by waiting for traffic lights. At the same time, the use of underground passages on the roadbed can achieve fast and smooth passage directly under the road. Usually, a pump is installed under the underground passage. To prevent rainy weather, resulting in more rain and safety problems, some emergency strategies will be adopted at present. [0003] However, the current underground passages are mostly waterproof. Most of the pu...
