Abstract

The utility model provides a rainwater permeable-type overflow well which is developed with the combination of an existing urban rainwater wastewater confluent drainage method in China so as to achieve the aims of permeation, sediment collection, stream guidance, overflowing and the like. A well mouth of the rainwater permeable-type overflow well (2) is provided with a rainwater well grate (1), two sides of the rainwater permeable-type overflow well (2) are respectively provided with a channel (9) which is in series connection with a rainwater permeable-type lateral ditch, a rainwater branch pipe (5) connected with an originally-laid sewer line is arranged on another side of the rainwater permeable-type overflow well (2). A vertical partition plate (4) is installed at the bottom of the rainwater permeable-type overflow well (2). The wide side of the partition plate (4) is opposite to the well mouth, and an opening formed in the upper portion of the narrow side of the partition plate (4) is an overflow mouth (3). Permeable openings (8) are formed in the lateral wall of the rainwater permeable-type overflow well (2). The shape of each permeable opening (8) is in a rectangular platform type. Single-particle-size macadam layers (6) are adopted on the lower side and the lateral sides of the rainwater permeable-type overflow well (2). Water-permeable geotechnical cloths (7) cover the exteriors of the single-particle-size macadam layers (6). The rainwater permeable-type overflow well has the advantages of having the functions of collection, storage and rainwater permeation and being deeper in construction and capable of effectively precipitating dust, sludge, rubbish and the like in rainwater, and when a water level exceeds the range of the rainwater permeable-type side ditches, the rainwater can automatically flow out through the overflow mouth.

Description

Rain penetration type overflow well

Technical field

The utility model relates to the engineering that the urban road surfaces rainwater is collected and utilized, and is specifically related to a kind of rain penetration type overflow well.

Background technology

Because the hard increase that covers of urban road, most of with the sewage interflow or enter Wastewater Treatment Plant as the rainwater of one of main freshwater resources, perhaps because the disposal ability deficiency of municipal sewage plant, cause with effluent discharge to the rivers and creeks and the ocean, not only cause the waste of rainwater resource, and cause river and seawater pollution, heavy damage the ecological homeostasis.

Summary of the invention

The system engineering of urban road rainwater catchment system is the strong technical measures that solve urban road rainwater problem, and system engineering collects well, rain penetration type overflow well, rain penetration type checking well by rain penetration type lateral sulcus, rainwater and five cores of rainwater storage pool make up and accessory structure is formed.

The utility model provides a kind of rain penetration type overflow well, researches and develops in conjunction with the drainage pattern at the dirty interflow of China existing city rain, reaches infiltration, collection silt, water conservancy diversion, purpose, make the rain penetration system have bigger retaining and drainability

The utility model rain penetration type overflow well ⑵ well head is installed catch-basin grate ⑴, and rain penetration type overflow well ⑵ two wing passage ⑼ connect with rain penetration type lateral sulcus, and opposite side arranges mozzle ⑸ and is connected with the original sewer pipe of laying; It is relative with well head that rain penetration type overflow well ⑵ bottom is equipped with the wide side of vertical clapboard ⑷, dividing plate ⑷, and a narrow upper lateral part is uncovered to communicate with mozzle ⑸ for overfall ⑶; Rain penetration type overflow well ⑵ sidewall is provided with infiltration mouthful ⑻, permeates the rectangular bench-type that is shaped as of mouthful ⑻ opening; Simple grain degree macadam ⑹ is adopted in the following and side of described rain penetration type overflow well ⑵, the permeable geotextiles ⑺ of the outside covering of simple grain degree macadam ⑹.

The utility model is helpful to be: have the rain penetration function; Construct deeplyer, can precipitate dust in the middle of the rainwater, mud, rubbish etc. effectively; When the excessive infiltration ditch storage of rainwater is full, by mozzle unnecessary rainwater water conservancy diversion is discharged in the original sewer pipe of laying, make the rain penetration system have bigger retaining and drainability.

Description of drawings

The present invention is further detailed explanation below in conjunction with accompanying drawing and the specific embodiment.

Fig. 1 is rain penetration type overflow well master sectional view schematic diagram;

Fig. 2 is the right sectional view schematic diagram of rain penetration type overflow well.

Illustration: catch-basin grate 1, rain penetration type overflow well 2, overfall 3, dividing plate 4, mozzle 5, simple grain degree macadam 6, permeable geotextiles 7, infiltration mouthfuls 8, with rain penetration type lateral sulcus passage 9.

The specific embodiment

As depicted in figs. 1 and 2, rain penetration type overflow well 2 structures are like this: well head is installed turnover type catch-basin grate 1, with the road surface isoplanar; Rain penetration type overflow well 2 both sides are provided with passage 9, and opposite side arranges mozzle 5 and is connected with the original sewer pipe of laying; It is relative with catch-basin grate 1 that rain penetration type overflow well 2 bottoms are equipped with a side of vertical clapboard 4, dividing plate 4, and the opposite side open topped is that overfall 3 communicates with mozzle 5; Rain penetration type overflow well 2 structures are darker; Rain penetration type overflow well 2 sidewalls are provided with infiltration mouth 8, permeate the rectangular bench-type that is shaped as of mouthful 8 openings; Simple grain degree macadam 6 is adopted in the following and side of rain penetration type overflow well 2, the permeable geotextiles 7 of simple grain degree macadam 6 outside coverings.According to the road Longitudinal Slope For Grade Line, calculate the interval of the rain penetration type overflow well 2 that needs setting, determine the position that arranges of osmosis type overflow well 2 according to the counting period.

The setting of connecting with rain penetration type lateral sulcus of the passage 9 of rain penetration type overflow well 2 both sides; When below rain penetration type lateral sulcus is arranged on kerb, rain penetration type overflow well 2 also is arranged on below the kerb, is actually to have replaced the roadside rainwater to collect well, and rainwater flows directly into rain penetration type overflow well 2; When below rain penetration type lateral sulcus is not arranged on kerb, rain penetration type overflow well 2 needs to be located at same position with rain penetration type lateral sulcus, the roadside arranges rainwater and collects well (being drain gully), after rainwater collection well is collected rainwater, by pipeline with storm-water drainage to plain edition rain penetration well or also can be discharged into rain penetration type overflow well 2, rain penetration type overflow well 2 in rain penetration type lateral sulcus, carries out naturally osmotic to underground by rain penetration type lateral sulcus with storm-water drainage afterwards.Dust in the middle of the rainwater that rainwater collection well is collected, mud, rubbish etc. precipitate effectively at rain penetration type overflow well 2 deep-wells, avoid flowing in the rain penetration type lateral sulcus, can effectively prevent from permeating the obstruction of mouth 8; Can regularly clean mud and rubbish that well head catch-basin grate 1 accumulates, for preventing from reducing the rain penetration effect of whole system, play key effect.When the water yield exceeds the scope of rain penetration type lateral sulcus, water level in the rain penetration type overflow well 2 namely surpasses dividing plate 4, at this moment rainwater is crossed dividing plate 4 automatically, flow out along overfall 3 and mozzle 5, be discharged in the sewer pipe of original laying, enter Wastewater Treatment Plant and handle, avoiding rainwater to overflow ground influences traffic.
