Description

Road side sub-belt concave green land water seepage pavement structure

Technical Field

The utility model relates to a municipal administration technical field, concretely relates to concave greenery patches infiltration of road side subband structure of mating formation.

Background

In the sponge city design, most of rainwater flows into the seepage well firstly, and is discharged into the water collecting well after the rainwater stored in the green belt is full, and then is discharged into a municipal rainwater pipeline. By utilizing the sponge urban seepage well in the form, the condition that sundries and silt are silted up in the seepage well is reduced. The clogging of the seepage well easily causes the clogging of the blind pipe, the clogging of the drainage blind pipe influences the smoothness of the whole drainage system, and the pipeline renovation cost is quite high.

The sponge city design comprises a sidewalk permeable pavement design and a road side sub-belt concave green land design. And a seepage well and an overflow well are arranged in a green land with a concave part on the side zone of the road. In the original design, the cobblestones are filled in the circumferential width range of 20cm of the downward part of the seepage well mouth, and the design of expanding the circumferential range of the seepage well has a leak.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a concave greenery patches infiltration structure of mating formation of road side subband is provided, can reduce road pavement debris, silt flow in the side subband afforestation, weaken the surface runoff through the greenbelt to the washing away of side subband greenery patches soil.

Based on the above problem, the utility model provides a technical scheme is a concave greenery patches infiltration of road side subband structure of mating formation, pack the infiltration well of cobblestone all around including its lower extreme, set up the through-hole in the middle of the motor vehicle road curb relative with the infiltration well, through-hole department installs the filter screen, lays the longitudinal section that the slope set up downwards between motor vehicle road curb and the infiltration well and be the first cobblestone layer of falling trapezoidal, and the second cobblestone layer that the circle form set up is filled in the infiltration well head outside, and the infiltration well periphery is close to second cobblestone layer and puts things higher than the planar longitudinal section of afforestation soil layer and is trapezoidal third cobblestone layer, geotechnological cloth is all laid to first cobblestone layer, second cobblestone layer and third cobblestone layer bottom.

The side surface of the part of the first cobble layer close to the motor vehicle road kerb is matched and connected with the side surface of the concrete prop at the motor vehicle road kerb.

Furthermore, one end of the first cobble layer, which is far away from the roadside stone of the motor vehicle lane, is respectively connected with the outer ring edge of the second cobble layer and two free ends of the third cobble layer.

Wherein the third cobble layer is 5-10 cm higher than the plane of the greening soil layer.

Further, the cross section of the third cobble layer is 15cm wide at the top, 30cm wide at the bottom and 20cm high.

The filter screen is made of galvanized iron wire and fixed on the back of the motor vehicle road kerbstone, and two ends of the filter screen are poured in concrete.

The utility model has the advantages and beneficial effect:

the method has the advantages that the cobblestones are used for manufacturing the periphery of the infiltration well into a trapezoidal dam type structure which is higher than a green soil layer, so that the situation that the green belt water flow is too large when rainfall is large and the green soil layer is flushed into the infiltration well is avoided; a first cobble layer which is obliquely and downwards arranged is laid between the roadside stones of the motor vehicle lane and the seepage well, so that sundries and silt on the road surface can be reduced from flowing into the side sub-belt greening, and the scouring of surface runoff of a green belt to the side sub-belt greening soil is weakened; by using the geotechnical material, the mixing of a greening soil layer and cobblestones is avoided, and the filtering effect of the cobblestones is weakened; the technological improvement of the form greatly reduces the input cost of personnel maintenance in the quality guarantee period and the operation stage of the rain sewage pipeline, reduces the risk of blockage and rework of the blind pipe, and has a great application prospect.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1-2, a road side sub-zone concave greenbelt water seepage pavement structure comprises a seepage well 1, wherein cobblestones are filled around the lower end of the seepage well 1, a through hole 3 is formed in the middle of a motor vehicle road side stone 2 opposite to the seepage well 1, a filter screen 10 is installed at the through hole 3, a first cobble layer 5 with an inverted trapezoid longitudinal section is laid between the motor vehicle road side stone 2 and the seepage well 1, a second cobble layer 8 in a ring shape is filled outside the well mouth of the seepage well 1, a third cobble layer 7 with a trapezoid longitudinal section higher than the plane of a greening soil layer 9 is laid on the periphery of the seepage well 1 close to the second cobble layer 8, and geotextiles 6 are laid at the bottoms of the first cobble layer 5, the second cobble layer 8 and the third cobble layer 7.
