Underground building opening flood prevention facility

Abstract

The invention discloses an underground building opening flood prevention facility. A movable baffle, a movable baffle shaft, an elevating steel cable and an elevating cable winch are included. The elevating steel cable is arranged on side barricades on the two sides of a ground inlet and outlet port of an underground building. The movable baffle is hinged to the movable baffle shaft. The two endsof the movable baffle shaft are borne on the elevating steel cable. The elevating steel cable can drive the movable baffle shaft to ascend. The movable baffle and the movable baffle shaft are locatedin a ramp in the ground inlet and outlet port of the underground building, a water level induction controller is located on the basement side wall nearby the ramp bottom of the underground building, and a signal connecting wire of the water level induction controller is embedded in the ramp side wall of the underground building. The underground building opening flood prevention facility conducts implementation through the current existing engineering technology, additional secondary development is not needed, system manufacturing is simple, usage is convenient, and social benefits are obvious.By means of the underground building opening flood prevention facility, the situation that rainwater flows backwards into the underground building under the situation of the suddenly-happening urbaninland inundation is effectively prevented, and the response capability for the flood caused by the suddenly-happening intense fall is improved.

Description

technical field [0001] The invention relates to the field of underground buildings, in particular to an exposed flood control facility for underground buildings. Background technique [0002] my country has a large population and little land, and is a country with small resources per capita. Therefore, we should cherish our land resources more. Underground space has been regarded as a precious natural resource owned by human beings and has not been developed in large quantities so far. The development and utilization of underground space is a more realistic way to open up new living spaces. This is of great significance to the survival and development of human beings under the background that the world's population is increasing and the land suitable for living on land is decreasing day by day. [0003] Due to the rapid development in the first 30 years, our country has achieved the vanguard position in the field of infrastructure construction in the world. Brilliant achie...

Problems solved by technology

[0006] In the prior art, rain gutters are generally designed at the beginning of the basement ramp and at the end of the ramp to the basement to properly block the ground rainwater. The disadvantage is that it can only block the flood below the normal rainfall in the state of no road surface water.

Another existing method is to use a platform of a certain height at the beginning of the basement ramp to block the rainwater on the ground, but the disadvantage is to increase the total length of the ramp

From the perspective of commonly used technologies at present, none of them can solve the threat of urban flooding to basement safety under rain and flood disaster weather while satisfying efficient use of land
