Description

Technical Field

[0001] The utility model relates to the technical field of basements, in particular to a building basement entrance structure. Background Art

[0002] The civil air defense basement is a part of the civil air defense project. When constructing high-rise residential buildings and public buildings, the underground garage is often used for civil air defense projects. It can be used as an underground garage in peacetime and as a shelter for personnel, materials, professional air defense teams and their equipment in wartime.

[0003] For example, after searching, the utility model patent with Chinese patent publication number CN207453580U discloses: a horseshoe-shaped underground garage entrance structure, including a driving road in front of the garage and an entrance ramp connecting the driving road in front of the garage with the underground garage, characterized in that: it also includes a drop-off road located above the entrance ramp, the drop-off road is horseshoe-shaped, and the two ends of the drop-off road are respectively located on both sides of the entrance ramp and connected to the driving road in front of the garage, and the drop-off road and the entrance ramp are distributed on the same side of the driving road in front of the garage. By setting up the drop-off road, vehicles can drop off passengers on the drop-off road before entering the underground garage. Compared with dropping off passengers directly on the driving road in front of the garage, congestion on the driving road in front of the garage is avoided, so that the entrance of the underground garage can meet the requirements of dropping off passengers and the requirements of vehicles entering the garage;

[0004] However, the above existing devices still have the following problems in actual use:

[0005] The above-mentioned existing device only prevents rainwater from being discharged into the basement through the entrance through the canopy. However, when encountering heavy rain, rainstorm and other weather with heavy precipitation, the accumulation of rainwater is likely to cause rainwater to flow back from the building base into the basement. The traditional flood prevention measure is to pile up sandbags at the entrance of the basement. However, the sandbags are not stable enough when the water level is high and are prone to collapse. At this time, rainwater will quickly flow into the basement, causing property losses and even safety accidents. Therefore, we propose a building basement entrance structure to solve the above-mentioned problems. Utility Model Content
