Abstract
The utility model discloses a fast-draining rain cap comprising a cap portion configured with a conicity, the diameter of the lower end of the cap being larger than that of the upper end, the surface of the cap portion being provided with plural draining gratings around the circumference of the cap, wherein the drainage gratings are configured in shape of triangle prism upon horizontal projection, spacing of the bottom of the drainage gratings being larger than that of the top; wherein the top of the cap portion is provided with dredge holes. The utility model can directly be fastened to the drainage outlet and block junks in the periphery of the cap portion, thereby making possible for accumulated water to be drained to the pipe system from drainage gratings. As the accumulated water is drained completely, leaves and other solid junks in the periphery of the drainage outlet can be blown away by strong wind generated by passing subway vehicles. Therefore, the utility model can satisfy drainage requirements of closed bridge floor during flood season, completely eliminating serious safety issues due to flooding induction plate when vehicles are operating in rain season existing in prior art bridge floor vehicles.
Description
Technical field
The utility model relates to the drainage system technical field, especially relates to the used drainage fitting of a kind of subway viaduct drainage system.
Background technology
After the floor drain of light rail viaduct is finished by the bridge professional construction, find that when experiencing rainy season the rainwater alluvial is serious, even flood tablet that this situation serious threat is to the normal safe handling of train.
The viaduct of light rail belongs to the closed pontic in both sides, and floor drain is installed in the evacuation platform below in the middle of two tracks, and the floor drain installed surface is concordant with draining ground, adorns a place every 50 meter amperes.Under natural environment influence, foreign material such as a large amount of leaves, polybag are easy to deposit on the floor drain outfall in being subjected to the washing away, drift about of strong wind heavy rain, thereby cause original outfall to stop up.After rainy season, outfall was stopped up, along with solid sundries is cumulative, rainwater was long-pending more dark more, just can form vicious circle.
Through repeatedly at the scene check and anatomize the reason that the ponding problem exists, pinpointing the problems mainly is on the floor drain outfall.When solid sundries is deposited on the ground leak, under the effect of gravity and siphon, solid sundries can be adsorbed on the ground drain surface securely, even arrange the labor cleaning also very difficult like this.
The key that solves bridge floor ponding problem is whether draining in time, if ponding can in time be drained, solid sundries on the viaduct will be blown away by the powerful blast that train operation brings, and outfall just can unimpeded draining under the situation that no solid sundries is stopped up.Therefore, open-air this particular surroundings of bridge floor need be installed big discharge capacity, is not afraid of fast row's rainwater installation of foreign material alluvial, but the dewatering installation of selling in the market all can't satisfy this demand.
The utility model content
The purpose of this utility model is to provide a kind of fast row's rainwater cap, and it has the advantages that big discharge capacity does not have obstruction, can guarantee the draining demand of open-air bridge floor.
For achieving the above object, fast row's rainwater cap of the present utility model has the cap body of a band tapering, and the diameter of cap body lower end is greater than upper end diameter, and the cap surface along the circumferential direction offers a plurality of drainage grill.
Described drainage grill is prism-shaped triangular in shape on horizontal projection, and the spacing of drainage grill bottom is greater than the spacing at top.
Described cap body top offers dredging hole.
The beneficial effects of the utility model are: it can be directly mouthful be buckled in draining, foreign material can be blocked in around the cap body, ponding then can enter sewer pipe from drainage grill, after ponding had slowly been arranged, the solid sundries such as leaf around the outfall can be blown away by the powerful blast that the railcar operation produces.Satisfied the requirement of drainning off floodwaters flood season of closed bridge floor fully, thoroughly solved former bridge floor train rainwater when moving rainy season and flooded the major safety risks that tablet causes.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an elevation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See illustrated in figures 1 and 2: fast row's rainwater cap of the present utility model adopts the moulding of centrifugal ductile cast iron casting, centrifugal ductile cast iron intensity is big, good toughness, metal consumption is few, casting labour intensity is little, and can bear higher pressure, it is stronger to resist track stray electrical current ability simultaneously.
Fast row's rainwater cap of the present utility model has the cap body 10 of a band tapering, the diameter of cap body 10 lower ends is greater than upper end diameter, cap body 10 surfaces along the circumferential direction offer a plurality of drainage grill 11 in horizontal projection prism-shaped triangular in shape, and the spacing of drainage grill 11 bottoms is greater than the spacing at top.Like this, foreign material can be blocked in around the cap body 10, and ponding then can enter sewer pipe from drainage grill 11, and after ponding had slowly been arranged, the foreign material such as leaf around the outfall can be blown away by the powerful blast that the railcar operation produces.
In addition, cap body 10 tops offer circular dredging hole 12, its effect is if drainage pipe stops up, under the situation of not removing fast row's rainwater cap, just can dredge drainage pipe, therefore, fast row's rainwater cap of the present utility model not only has the function of big discharge capacity, and the drainage pipe that can dredge fast in particular cases stops up.
Claims (3)
1. arrange the rainwater cap soon, it is characterized in that: it has the cap body of a band tapering, and the diameter of cap body lower end is greater than upper end diameter, and the cap surface along the circumferential direction offers a plurality of drainage grill.
