Abstract

The utility model provides a sand preventing structure for a rainwater pipe opening, and relates to the field of municipal drainage. By the sand preventing structure for the rainwater pipe opening, the possibility of silting of the rainwater pipe opening is reduced. According to the technical scheme, a rainwater pond and a desilting basin are arranged below a rainwater cover; a partition is arranged between the rainwater pond and the desilting basin; the height of the partition is half of the depth of the rainwater pond; an inclined water draining hole is formed in the upper portion of the partition; water seepage holes are formed in the bottom of the rainwater pond and the bottom of the desilting basin; a water draining pipe opening is formed in a side surface of the rainwater pond; a dustproof dustpan is positioned below the rainwater cover; the tail of the dustproof dustpan is hung at the edge of the top of the rainwater pond; an opening end of the dustproof dustpan is placed on the partition; the dustproof dustpan is downwards inclined from the tail to the opening end; and a water draining hole is formed in a side surface of the dustproof dustpan. The sand preventing structure has the advantages that dust and sundries are accumulated in the dustproof dustpan, and are scoured to the desilting basin by water; the risk on blockage of a water draining pipe due to accumulation of sand is effectively reduced; and a normal water draining function is not affected by accumulation of the sand.

Description

A kind of rain pipe road junction sand-prevention structure
Technical field
The present invention relates to the urban sewerage and drainage field, particularly the storm sewer entrance, reduce a kind of structure that silt enters storm sewer.
Background technology
In city, the drain hole of rainwater cover does not hide, and environmental sanitation is swept while cleaning at ordinary times, and the silt in rubbish and tiny foreign material easily enter under rainwater cover.Be deposited in the rain pipe road junction, easily caused before rainy season set, the rain pipe road junction is stopped up, and can't realize draining, causes the city waterlogging.
Summary of the invention
For reducing the silting at rain pipe road junction, the present invention designs a kind of rain pipe road junction sand-prevention structure.
The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of rain pipe road junction sand-prevention structure, by rainwater cover, stormwater tank, sand trap and dustproof dustpan form, it is characterized in that: rainy pond and sand trap under rainwater cover, the rainy water cover drain hole of rainwater cover part above stormwater tank, the rainwater cover on the sand trap top water cover drain hole that partly do not rain, a dividing plate is arranged between stormwater tank and sand trap, the height of dividing plate is half of the stormwater tank degree of depth, the partition board drainage hole of inclination is arranged at the top of dividing plate, direction from the sand trap to the stormwater tank, the partition board drainage hole incline direction is for being inclined upwardly, water seepage hole is arranged at the bottom of stormwater tank and sand trap, and water seepage hole is bottom through-hole, there is drain pipe port the side of stormwater tank, a dustproof dustpan is positioned at the below of rainwater cover, the afterbody of dustproof dustpan hangs over the top of stormwater tank, the openend of dustproof dustpan is shelved on dividing plate, and dustproof dustpan presents the state being tilted to from tail end to openend, and there is dustproof dustpan drain hole the side of dustproof dustpan.
The acclivitous angle of partition board drainage hole is 45 degree.Dividing plate is a prismatoid, and bottom width is 2 times of upper end width, and the upper end width is 1-5cm.The diameter of partition board drainage hole is 1-2cm.The water seepage hole diameter is 1-2cm.The bottom of the distance from bottom stormwater tank of drain pipe port is 10-20cm.The diameter of the dustproof dustpan drain hole of dustproof dustpan is 2cm, and Center Gap is 3cm each other.
The invention has the beneficial effects as follows: environmental sanitation cleaning or other reasons drop at ordinary times dust or foreign material are to be deposited in dustproof dustpan, at first rinse dustproof dustpan after sprinkling truck or rainwater enter, and dust and foreign material are washed into to sand trap; If partition board drainage hole has been stopped up in the sedimentation of sand trap, rainwater enters stormwater tank by the dustproof dustpan drain hole of dustproof dustpan side, then enters the drain pipe port of drainage pipe; Device of the present invention can effectively reduce the obstruction risk of silting to drainage pipe, and the accumulation of silt, can not affect normal drain function.

The specific embodiment
A kind of rain pipe road junction sand-prevention structure, by rainwater cover 7, stormwater tank 1, sand trap 2 and dustproof dustpan 9 form, 7 times rainy ponds 1 of rainwater cover and sand trap 2, the rainy water cover drain hole 8 of rainwater cover 7 part above stormwater tank 1, the rainwater cover on the sand trap 2 tops water cover drain hole that partly do not rain, a dividing plate 5 is arranged between stormwater tank 1 and sand trap 2, the height of dividing plate is roughly half of the stormwater tank degree of depth, the partition board drainage hole 4 of inclination is arranged at the top of dividing plate, 1 the direction from sand trap 2 to stormwater tank, the partition board drainage hole incline direction is for being inclined upwardly, the angle tilted is preferably 45 degree, dividing plate is a prismatoid, bottom width is 2 times of upper end width, the upper end width is 1-5cm, the diameter of partition board drainage hole 4 is 1-2cm, water seepage hole 3 is arranged at the bottom of stormwater tank 1 and sand trap 2, and water seepage hole 3 is bottom through-hole, and diameter is 1-2cm, makes the residual rain penetration of stormwater tank 1 and sand trap 2 to underground.
There is drain pipe port 6 side of stormwater tank 1, and the bottom of the distance from bottom stormwater tank 1 of drain pipe port 6 is 10-20cm.
Dustproof dustpan 9 afterbodys hang over the edge of stormwater tank 1, the openend of dustproof dustpan 9 is shelved on dividing plate 5, dustproof dustpan 9 presents the state being tilted to from afterbody to openend, with the angle of horizontal direction, at the 5-30 degree, there is dustproof dustpan drain hole 10 side of the dustpan that prevents dust.The diameter of the dustproof dustpan drain hole 10 of dustproof dustpan 9 is 2cm, and Center Gap is 3cm each other.
