Description
Technical field
The utility model relates to a kind of anti-blocking rain grid, belongs to technical field of drainage.
Background technology
The generation of present urban waterlogging, main cause is that Drainage Design is unreasonable, and flowing line is aging, pipe uses reason to be not good at.But existing rain grid lacks anti-blocking entered function, cause foreign material in inlet for stom water to pile up, it is not also freely an assignable cause that Water in Rainwater Drainage is removed.This rain water grate, based on special form of structure, has certain anti-blocking entered function, effectively can reduce the accumulation of foreign material in inlet for stom water, for smooth and easy draining creates conditions.
Summary of the invention
For overcoming the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of anti-blocking rain grid, and it has certain anti-blocking function entered, and effectively can reduce the accumulation of foreign material in inlet for stom water, for smooth and easy draining creates conditions.
For achieving the above object, a kind of anti-blocking rain grid is disclosed in the utility model first aspect, it comprises grid-like grate plate, and described grate plate is fastened and connected by upper strata grid and lower floor's grid and forms, and the upper water falling hole of upper strata grid and the lower water falling hole of lower floor's grid are staggered; The cross section of the rib of lower floor's grid is U-shaped, and bottom land has at least two water seepage holes; Frame and the middle rib of the rib of upper strata grid and lower floor's grid are thicker, and one of them is uniformly distributed fluted, and another correspondence is distributed with tenon, and tenon and groove fasten.
Further, frame and the middle rib of described lower floor grid are provided with groove, and frame and the middle rib of upper strata grid are provided with tenon.
Further, frame and the middle rib of described lower floor grid are provided with tenon, and frame and the middle rib of upper strata grid are provided with groove.
Further, the rib of described upper strata grid 1 is plane batten or inverted flute profile batten.
Compared with prior art the utility model has following characteristics and beneficial effect:
This rain water grate, based on special form of structure, has certain anti-blocking entered function, effectively can reduce the accumulation of foreign material in inlet for stom water, for smooth and easy draining creates conditions.

Reference numeral: water falling hole, 3-water seepage hole, 4-tenon, 5-groove under 1-upper strata grid, the upper water falling hole of 11-, 2-lower floor grid, 21-.
Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of anti-blocking rain grid, comprises grid-like grate plate, and described grate plate is fastened and connected by upper strata grid 1 and lower floor's grid 2 and forms, and the upper water falling hole 11 of upper strata grid is staggered with the lower water falling hole 21 of lower floor's grid; The cross section of the rib of lower floor's grid 2 is U-shaped, and bottom land has at least two water seepage holes 3; Frame and the middle rib of the rib of upper strata grid 1 and lower floor's grid 2 are thicker, and one of them is uniformly distributed fluted 5, and another correspondence is distributed with tenon 4, and the two fastens.
Concrete, frame and the middle rib of described lower floor grid 2 are provided with pin hole, and the correspondence position of described upper strata grid 1 is provided with pin; Or the frame of described lower floor grid 2 and middle rib are provided with pin, the correspondence position of described upper strata grid 1 is provided with pin hole.
The rib of described upper strata grid 1 is plane batten or inverted flute profile batten.
Under normal circumstances, rainwater flows to inlet for stom water by the space between upper strata grid and lower floor's grid.Remain in the water in lower floor's flute profile grid, got rid of by the water seepage hole being arranged on 2 diameters 10 millimeters on grid.Due to the barrier effect of lower floor's flute profile grid, the foreign material such as leaf, polybag are blown away because cannot directly fall into inlet for stom water.
See Fig. 3 and Fig. 4, the prefabricated mould corresponding with lower floor's cell structure to upper strata grid, then casts respectively, places 24h and is cured, then by the artificial demoulding; Connect in pin joint mode after having cast; It is the pin of 8mm that upper and lower two parts arrange 6 diameters on two long limits and middle reinforced rib place, and corresponding pin hole diameter is 10mm.Space between pin and pin hole can be carried out fastening with plastic rubber ring.The material that casting adopts is ductile iron, steel grating or engineering plastics.
