Detailed Description
The utility model will now be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the utility model.
Example 1:
as shown in fig. 1, the bridge rainwater collecting well device provided by the embodiment of the utility model comprises a water collecting well 1, a well cover 2 and a filtering grating plate 3; the water collecting well 1 is a box body structure with an open upper surface; the inside of the water collecting well 1 is divided into a water collecting cavity 101 and a water discharging cavity 102; a water discharge outlet 103 is formed in the side surface, far away from the water collecting cavity 101, of the water discharge cavity 102, a water discharge pipe directly connected with the water collecting well 1 on the bridge is transversely arranged, and the water discharge outlet 103 is communicated with the water discharge pipe transversely arranged, so that lateral water discharge of the water collecting well 1 is realized; the inner bottom surface of the water collecting cavity 101 is lower than the inner bottom surface of the water discharging cavity 102; the water collecting cavity 101 is communicated with the inside of the water discharging cavity 102; the filtering grating plate 3 is arranged between the water collecting cavity 101 and the water discharging cavity 102; the filtering grating plate 3 separates the water collecting chamber 101 from the water discharging chamber 102; the well cover 2 is arranged at the top of the water collecting well 1 in a covering manner; the part of the well cover 2 close to the water collecting cavity 101 is provided with a plurality of water inlets 204; the water inlet 204 opens directly into the water collecting chamber 101. When the bridge floor has ponding in rainy days, rainwater flows into the water collecting well 1 from the bridge floor, firstly, enter the water collecting cavity 101 of the water collecting well 1 from the water inlet 204 on the well lid 2, rainwater is collected to a certain height in the water collecting cavity 101, then enters the drainage cavity 102, flows into the drainage pipe from the drainage outlet 103 at the side edge of the drainage cavity 102 to drain the bridge, and as the bottom surface of the water collecting cavity 101 is lower than the bottom surface of the drainage cavity 102, sundries such as sediment and dregs entrained in the rainwater flowing into the water collecting well 1 are deposited once in the water collecting cavity 101, so that sundries such as sediment and the like flowing into the drainage pipe of the bridge are reduced, the possibility of occurrence of blockage of the drainage pipe is effectively reduced, and meanwhile, the filtering grating plate 3 between the water collecting cavity 101 and the drainage cavity 102 can intercept and filter relatively large garbage such as leaves and waste paper carried in the rainwater, and the problem of drainage blockage is further reduced.
The bridge rainwater collecting well device provided by the embodiment of the utility model can reduce impurities such as sediment and garbage entering a drain pipe, so that the problem of drain blockage is effectively reduced, and the drainage efficiency of the air bridge deck in rainy days is ensured.
