Abstract

The utility model discloses a dustproof rain cover at the roadside, relates to the field of urban sewerage and drainage, and particularly relates to the technology for reducing blockage of pipelines. An urban rainwater cover is directly communicated with a drainage pipeline, blockage can occur easily, and the dustproof rain cover at the roadside is designed to avoid the blockage of the drainage pipeline. According to the technical scheme, the dustproof rain cover at the roadside is composed of a drainage area, draining pipes and a desilting area, wherein the rain cover is placed at the roadside, the drainage area is lower than a road, the drainage area is provided with the draining pipes, the draining pipes are provided with draining holes, and the top end of each draining pipe is flush with the road. The desilting area is arranged on one side of the drainage area, far away from the road, the desilting area is lower than the drainage area, and water seepage holes are formed in the bottom of the desilting area. The dustproof rain cover at the roadside has the advantages that due to the fact that the drainage area is lower than the road, rainwater can better gather towards the drainage area; the desilting area is lower than the drainage area, and the rainwater enables sundries on the ground of the drainage area to be flushed to the desilting area to subside first; the draining holes tilt upwards, silt is reduced, and floating objects are prevented from entering the drainage pipeline; and due to the fact that the diameter of each draining hole is one centimeter, large sundries are prevented from entering the drainage pipeline.

Description

The anti-dust-shower lid in a kind of road roadside

Technical field

The present invention relates to the urban sewerage and drainage field, particularly reduce foreign material and silt enters drainage pipe, reduce the technology of line clogging aspect.

Background technology

Rainwater lid and the drainage pipe in city are directly to be communicated with, according to the principle that Water seeks its own level, rain covers last, it is exactly drainage pipe that the rain lid descends, for accelerating draining, the slit great majority of rain lid are the rectangle drain hole, long, wideer, most length at 2.5cm, causes a large amount of foreign material such as leaf, branch, small stone, silt to enter drainage pipe at 20cm, width, pushes ahead under rain drop erosion subsequently, cause the effective diameter of pipe of drainage pipe to diminish, even stop up, when raining, cause the city waterlogging easily.

Because it is foreign material descend to pile up at rain lid, and have pushed ahead a segment distance in pipeline, all smaller at the caliber of the storm sewer of China, can't hold the workman in the pipe interior constructing operation, thereby cleaning is also very inconvenient, and the degree of depth that can clear up is very limited, so can not be thoroughly.

Summary of the invention

For avoiding the obstruction of drainage pipe, the present invention designs the anti-dust-shower lid in a kind of road roadside.

The present invention realizes that the technical scheme that goal of the invention adopts is: the anti-dust-shower lid in a kind of road roadside, formed by catchment, gutter, desilting zone, it is characterized in that: the rain lid is positioned at the road roadside, the catchment is lower than road, there is gutter the catchment, gutter has drain hole, and the top of gutter is concordant with road; There is desilting zone the catchment away from a side of road, and desilting zone is lower than the catchment, and the infiltration hole is arranged at the desilting zone bottom.

There is the groove of annular the catchment, the form fit of groove and the gutter mouth of pipe, and gutter utilizes the weight of self to be fixed in the groove.

Gutter is pipe of cement, wall thickness 3-5cm, gutter external diameter 20-30cm, the high 30-50cm of gutter.

Gutter bottom first lap drain hole aperture lowest part apart from ground, catchment 1-2cm.

Direction in the export-oriented gutter of gutter, drain hole is inclined upwardly, preferred angled 30-60 degree.

Drain hole diameter 1cm, interval 2-3cm between the drain hole center.

Desilting zone is than the low 20-30cm in catchment.

The invention has the beneficial effects as follows: the catchment is lower than road, is beneficial to rainwater and assembles to the catchment; Desilting zone is lower than the catchment, and drain hole also has 1-2cm apart from ground, therefore rainwater is washed into desilting zone with the foreign material on ground, catchment earlier and carries out sedimentation, and desilting zone is positioned at the rightabout of current, the water of desilting zone remains static basically, is conducive to desilting and avoids desilting zone silt to be stirred by current; It is underground that the desilting zone bottom has the infiltration hole to be conducive to the ponding infiltration, avoids ponding to grow mosquito and bacterium; The groove of annular utilizes fixedly gutter of gravity, is conducive to the maintenance of gutter; Drain hole is inclined upwardly, and preferred angled 30-60 degree is conducive to reduce silt and avoids floating thing to enter drainage pipe; Drain hole diameter 1cm avoids entering drainage pipe than bigger material, and little foreign material can be drained under rainwash.

The specific embodiment

The rain lid is in road 1 roadside, catchment 2 is lower than road, being beneficial to water flows to the catchment, there is gutter 3 catchment, gutter has drain hole 4, gutter is pipe of cement, wall thickness 3-5cm, gutter external diameter 20-30cm, the high 30-50cm of gutter, first lap drain hole 4 aperture lowest parts are apart from ground, catchment 1-2cm, direction in the export-oriented gutter of gutter, and drain hole is inclined upwardly, preferred angled 30-60 degree, avoid floating thing and reduce silt entering drainage pipe, drain hole diameter 1cm avoids big foreign material to enter drainage pipe, the top of gutter is roughly concordant with road, there is desilting zone 5 catchment 2 away from a side of road, and desilting zone 5 is than the low 20-30cm in catchment, and infiltration hole 6 is arranged at the desilting zone bottom.

There is the groove of annular catchment 2, the form fit of groove and the draining mouth of pipe, gutter 3 utilizes the weight of self to be fixed in the groove, roughly press husky density 2.5g/cm3 according to wall thickness 3cm, external diameter 20cm, the high 30cm of gutter, cement density, gutter 3(gutter herein is the entrance of drainage pipe in fact, is equivalent to a tall paper hat and is worn over the pipeline top, and is simple for what explain, under the situation that can not give rise to misunderstanding, abbreviate gutter as in the paragraph in front) 25 kilogram weights roughly.
