Abstract

The invention relates to a rain water seepage well lid for an urban green land, which comprises a well frame and a well lid. The rail water seepage well lid is characterized in that the well lid adopts a cone frustum type recess; a perforation plate card is arranged in the cone frustum type recess; a perforation plate is lapped on the perforation plate card to divide the well lid into an upper layer and a lower layer; the upper layer adopts a vegetation planting layer; and the lower layer adopts a water storage layer; the outer edge of the well lid is lapped on circular grids of the well frame; the well frame consists of a circular ring, a soil retaining ring and the circular grids; the soil retaining ring is arranged above the well frame; the diameter of the soil retaining ring is equal to the outer diameter of the circular ring; and the circular grids are vertically mounted on the edge of the inner diameter of the circular ring. The upper layer of the well lid adopts the vegetation planting layer; redundant rain water collected by the well lid when rain falls can be stored in the water storage layer, and is used for the growth of vegetation in a lid plate in the non-rain falling period. And the well lid can improve the overall aesthetics of the green land under the condition of not influencing water entrance.

Description

Urban green space rainwater infiltration well lid

Technical field

The present invention relates to a kind of urban green space rainwater infiltration well lid, belong to urban rainwater control and utilize the field.

Background technology

Accelerate along with urbanization speed, waterproof ground, city significantly increases, and causes the city overland runoff coefficient to increase, so that the metropolis is because the burst heavy rain, the waterlogging that ponding causes, the disaster scenarios it of flood occur in succession.In order to solve problems, in recent years, the use of up concave type greenery patches in the city is more and more universal, use the effect that there are recharge of groundwater, regulated flow, flood detention in the up concave type greenery patches and subdue Runoff contaminants in the city, for the penetrating power of rainwater is provided, generally meeting meeting dispersed placement negative well in the greenery patches serves as underground captation by negative well, after the rainwater savings, utilize the space between rubble in soil all around, to spread.The rainwater infiltration well lid that adopts at present is traditional catch basin cover, and vegetation can't be planted in the well lid surface, so that the rainwater negative well seems eye-catching especially in the greenery patches, affects the overall appearance in greenery patches, therefore, is necessary to make improvements.

Summary of the invention

The object of the present invention is to provide a kind of urban green space rainwater infiltration well lid, it can make the rainwater that collects in the negative well periphery, flowed in the negative well by ring grille, ring grille can be with the large particle diameter impurity interception in the rainwater outside negative well, plant vegetation on the well lid, make negative well and greenery patches form integral body, do not affect the overall appearance in greenery patches.

Technical scheme of the present invention is achieved in that urban green space rainwater infiltration well lid, is made of crib, well lid; It is characterized in that: well lid is the desk-top groove of cone, in the desk-top groove of cone the perforation integrated circuit board is set, perforated plate is taken and is placed on the perforation integrated circuit board, and is two-layer about well lid is divided into, and the upper strata is vegetation plantation layer, lower floor is aquifer, take on the ring grille that is placed on crib the well lid outer, and crib is comprised of annulus, gear soil ring, ring grille, and gear soil ring is above crib, diameter is identical with the annulus external diameter, and ring grille is vertically mounted on the internal diameter edge of annulus.

Described crib and well lid are cast iron or recycled plastics.

Described annulus width is 5-10cm; The height of gear soil ring is 5-10cm; The grizzly bar cross section is circular, and the grizzly bar height is highly identical with gear soil ring, and the adjacent grill spacing is 2-5cm.

Described well lid is comprised of well lid outer and the desk-top groove of cone, and well lid outer width is 2-3cm, and the external diameter of well lid outer is than the large 1-2cm of crib internal diameter; The desk-top groove height of cone is 15-20cm.

Described aquifer height is 5-10cm.

Evenly perforate on the described perforated plate, the aperture is 4-8mm, percent opening is at 20%-40%.

Good effect of the present invention is that landscape effect is good, compares with traditional infiltration well lid, in the situation that does not affect the water inlet effect, can plant vegetation on the well lid, makes the existence of negative well not affect the globality in greenery patches; Vegetation is difficult for withered on the cover plate, compare with the existing well lid that can plant vegetation, greenery patches rainwater infiltration cover plate vegetation plantation layer is arranged with aquifer, and the unnecessary rainwater that cover plate is collected when rainfall can be stored in the aquifer, and the growth that is used for non-flush period cover plate vegetation is required.

The specific embodiment

The present invention will be further described below in conjunction with accompanying drawing: shown in Fig. 1-5, environment-friendly type infiltration well lid is made of crib 1, well lid 2; It is characterized in that: well lid is the desk-top groove of cone, perforation integrated circuit board 8 is set in the desk-top groove 12 of cone, perforated plate 7 is taken and is placed on the perforation integrated circuit board 8, and is two-layer about well lid 2 is divided into, and the upper strata is vegetation plantation layer 9, lower floor is aquifer 6, take on the ring grille 4 that is placed on crib 1 well lid 2 outers 5, and crib 1 is comprised of annulus 10, gear soil ring 3, ring grille 4, and gear soil ring 3 is above crib, diameter is identical with annulus 10 external diameters, and ring grille 4 is vertically mounted on the internal diameter edge of annulus 10.

Described crib 1 and well lid 2 are cast iron or recycled plastics.

Described annulus 10 width are 5-10cm; The height of gear soil ring 3 is 5-10cm; Grizzly bar 11 cross sections are circular, and grizzly bar 11 height are highly identical with gear soil ring 3, and the adjacent grill spacing is 2-5cm.

Described well lid 2 is comprised of well lid outer 5 and the desk-top groove 12 of cone, and well lid outer 5 width are 2-3cm, and the external diameter of well lid outer 5 is than the large 1-2cm of crib internal diameter; The desk-top groove 12 of cone highly is 15-20cm.

Described aquifer 6 highly is 5-10cm.

Evenly perforate on the described perforated plate 7, the aperture is 4-8mm, percent opening is at 20%-40%.

During use well lid 2 is put into crib 1, just in time take on the ring grille 4 that is placed on crib cover plate outer 5, and perforated plate 7 is placed on the perforation integrated circuit board of well lid 28, makes well lid 2 form vegetation plantation layer 9 and aquifers 6, the plantation vegetation of banketing in vegetation plantation layer 9; Negative well periphery rainwater flows into crib 1 along gear soil ring 3 during work, and rainwater enters in the negative well by grid 4, and large impurity is trapped within outside the grid 4; Well lid top rain penetration enters vegetation plantation layer 9 in the rainfall, and unnecessary rainwater can enter in the aquifer 6 by perforated plate 7, and the vegetation growth that is used for non-flush period well lid 2 is required.
