In another better embodiment of the present utility model, the inner side edge of the device that intercepts water is provided with notch and connects with the chute with gathering-device.
In another better embodiment of the present utility model, gathering-device is positioned at the bottom, device catchwater two ends of intercepting water and is provided with the breach that is used to fall into water.
In another better embodiment of the present utility model, dewatering installation includes gutter.This gutter is connected with the chute and the city subsurface stormwater discharge tube of gathering-device respectively.
In another better embodiment of the present utility model, dewatering installation is connected on the base of the device that intercepts water.Dewatering installation is not connected on its side, has guaranteed that rainwater is discharged fast in it.Wherein dewatering installation is to be connected with captation indirectly by the device that intercepts water, if the device that intercepts water is not set, then dewatering installation can directly be connected with the chute of captation.
In another better embodiment of the present utility model, dewatering installation is provided with anti-blocking floor drain with the position that the device that intercepts water joins, and guarantees the unimpeded of drainage pipe.
In another better embodiment of the present utility model, the concealed type rain water collecting system also includes the drip that is arranged at prefabricated cover plate plate seam place.Drip places the top of chute, prevents that rainwater is along last overlay basal slip water clock.
In another better embodiment of the present utility model, prevent that prefabricated cover plate unfilled corner from falling limit and other impact wreckages and the rain leakage that causes, the concealed type rain water collecting system also comprises the cornerite steel that is arranged on its peripheral contact surface, and it is protected.
Compared with prior art, technique effect of the present utility model is, has disguise, do not influence advantages such as ground surface function and waterproof be efficient.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is a kind of three-dimensional cut-away illustration that is arranged at the embodiment of concealed type rain water collecting system under the prefabricated cover plate that the utility model relates to;
Fig. 2 is the concealed type rain water collecting system cross-sectional view strength that is arranged under the prefabricated cover plate shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2, a specific embodiment of a kind of concealed type rain water collecting system that the utility model relates to, the below that it is arranged at ground 200 prefabricated cover plates 210 comprises the device 110 that intercepts water, gathering-device, dewatering installation 130 and attached structure.
