Urban traffic culvert or tunnel entrance and exit waterproof flood shelter device and method

Abstract

The invention provides a water logging-preventing shielding device and method for an inlet and outlet of an urban traffic culvert or tunnel. The shielding device comprises a traction system, a left expansion bracket, a right expansion bracket, a left guide rail, a right guide rail, an arch-shaped supporting rack and a water-isolating covering layer. The left guide rail and the right guide rail are symmetrically paved on a slope of the inlet of the culvert or the tunnel and extend to the top of the slope; the left expansion bracket and the right expansion bracket are symmetrically arranged on two sides of the inlet and outlet of the culvert or tunnel, one of the sides is fixed on a wall body of the culvert or tunnel, and the water-isolating covering layer externally sleeves the left expansion bracket, the right expansion bracket and the arch-shaped supporting rack. The device receives a command to brake through the traction motor to pull the expansion brackets to be unfolded along the guide rails. The supporting system is successively and fully unfolded to support the water-isolating covering layer to form a water-isolating channel at the inlet and outlet of the culvert or tunnel. The water logging-preventing shielding device provided by the invention provides a water-free traffic environment at the inlet and outlet of the culvert or tunnel, so that large area water accumulation to hamper traffic due to unsmooth drainage of the culvert and tunnel in a low terrain range and the like is avoided.

Description

technical field [0001] The invention belongs to the intersecting technical field of urban planning engineering and traffic road engineering, and in particular relates to an anti-flooding shielding device and method for an entrance and exit of an urban traffic culvert tunnel. Background technique [0002] With the advancement of urbanization, the urban population has grown rapidly, and the rapid improvement of the national economy has driven the rapid development of the automobile industry in the past ten years. The number of automobiles in Chinese cities has become the world's top. The status quo of rapid economic development has brought enormous pressure to urban transportation. Technical policies and measures such as dedicated bus lines, rail transit, tunnel traffic, urban subways, and odd-even number restrictions have been introduced one after another, all aimed at alleviating the increasingly serious transportation pressure. Three-dimensional traffic appears in the urban...

Problems solved by technology

[0004] At this stage, artesian drainage channels and water pumps are used to drain water, but both have limits, especially when the entire river basin and city are flooded, they will lose their effect. How to build a closed channel for traffic in a water environment is also an underground traffic structure system. An important direction of design
