Abstract

The utility model provides a road rainwater collecting and utilizing device. Particularly, the connection position of a gutter inlet and the road surface is provided with a rainwater perforaled strainer, the lower portion of the gutter inlet is a sedimentation area, a shell filter is arranged on the left side wall at the upper portion of the sedimentation area, the shell filter is of a drawer type structure, and longitudinal water distribution pipes are distributed on a water outlet. Peanut shells with the grain size ranging from 4mm to 6mm and walnut shells with the grain size ranging from 4mm to 6mm are selected as shuck filter materials. The gutter inlet is connected with an infiltration groove through the shell filter. The infiltration groove is in a long flat shape, the groove bottom is concave, and the top portion of the infiltration groove is communicated with an inspection well. A later period rain pipe is formed in the other side wall of the gutter inlet, and the height position of the later period rain pipe is higher than that of the shell filter. By means of the road rainwater collecting and utilizing device, on the basis that rainwater and dirt are separated, primarily-purified rainwater is used for compensating for underground water in an infiltration mode, and rainwater except the first rain is uniformly collected and utilized.

Description

Road rainwater collecting use device

Technical field

The utility model belongs to urban sewerage and drainage technical field, is specifically related to a kind of road rainwater collecting use device.

Background technology

At present China's urban sewerage and drainage system has combined system and separated drainage system, and the rainwater on road is collected and entered that soil pipe meets with or storm sewer by inlet for stom water.The higher early-stage rainwater of some pollutant load in the rainwater that road collects, it is not enough that present drainage system is processed this part early-stage rainwater, cause urban water-body pollution, strengthened sewerage treatment difficulty, and wasted clean rainwater resource of a large amount of later stages.

Summary of the invention

The utility model object is the deficiency existing for existing drainage system, and a kind of road rainwater collecting use device is provided, and effectively to process early-stage rainwater, slows down municipal sewage plant's pressure, makes full use of rainwater resource.

The technical scheme that the utility model provides is: during rainfall, the rainwater on road collects and enters inlet for stom water, utilizes the filtration of inlet for stom water top rainwater double-edged fine-toothed comb, by bulk solid material interceptions such as the rubbish in road rain water, leaves.In inlet for stom water bottom, be provided with settling zone, for the large granular impurity of sedimentation road rain water, to prevent that Fruit shell filtering device from stopping up.Top, settling zone left side wall is installed Fruit shell filtering device, and shell filtrate is peanut and walnut shell, and particle diameter is that 4mm is to 6mm.Fruit shell filtering device is designed to drawer type structure, is convenient for changing, and solves the shorter problem of useful life of Fruit shell filtering device.Road rain water flows to and infiltrates groove through Fruit shell filtering device.The cell body that infiltrates is long-pending to be determined by concrete early-stage rainwater amount, and groove height degree is less, guarantees and the certain distance of groundwater table, contributes to infiltrate.The shallow layout of the flute length that infiltrates, to reduce the excavation construction amount under sidewalk and to reduce the impact on underground various pipelines.The groove that infiltrates is connected with inlet for stom water by Fruit shell filtering device, and Fruit shell filtering device water outlet is laid with cloth tank, rainwater uniform-flow is entered and ooze in groove, and the operational paradigm of groove is infiltrated in raising.The trench bottom that infiltrates is spill, and department facilitates sedimentary focusing on.Top is connected with manhole, to prevent from infiltrating groove obstruction destruction.Road rain water infiltrate groove hold full after, in inlet for stom water, high-order overflow enters later stage rain pipe.

The beneficial effects of the utility model are, at the beginning of adopting 2 times, rain is processed (through Fruit shell filtering device, process and infiltrate groove and infiltrate processing), department is effectively to remove the pollutant in early-stage rainwater, early-stage rainwater after purification infiltrates recharge of groundwater on the spot, and unified collection of rainfall after deduction early-stage rainwater utilized.Reach the object that slows down municipal sewage plant's pressure, makes full use of rainwater resource.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited in described embodiment.

See Fig. 1 and Fig. 2, the device in this example is positioned between motorway (8) and sidewalk (9), and inlet for stom water (1) is established rain perforaled strainer (17) with road surface connecting place, by bulk solid material interceptions such as the rubbish in road rain water, leaves.Inlet for stom water (1) bottom is provided with settling zone (2), and settling zone (2) top left side wall is provided with a Fruit shell filtering device (3), and department is effectively to remove the most of pollutant in early-stage rainwater.Fruit shell filtering device (3) left side is for infiltrating groove (4), bottom land becomes prolate type, its bottom land is spill, bottom land filtration beds is the gravel packer (12) of geotextiles (11) parcel, infiltrating groove (4) top is connected with manhole (5), and is connected with inlet for stom water (1) by Fruit shell filtering device (3).At inlet for stom water (1) right side wall, have later stage rain pipe (7), later stage rain pipe (7) arranges highly just in time on Fruit shell filtering device (3), facilitates unified collection of later stage rainwater to utilize.

See Fig. 3, in this example, Fruit shell filtering device (3) is drawer type structure, permeable case (14) and shell filtrate (15), consists of, and is embedded in concrete wall (16), on water outlet, be provided with water distributor (6), which is provided with weep hole (13).It is that 4mm is to 6mm peanut and walnut shell that shell filtrate is chosen particle diameter.
