Description

Sponge city environment-friendly rainwater well
Technical Field
The utility model belongs to the technical field of rainwater recycle, concretely relates to sponge city environment-friendly rainwater well.
Background
Recently, the national inland inundation disasters are frequently reported, the defects of the traditional urban drainage mode are gradually revealed, the sponge city idea is greatly popularized nationwide, and various sponge city measures are also implemented in various regions, but the measures still have certain defects under certain conditions. For example, the traditional grass planting ditch mainly aims at transmission, and the runoff reduction amount is very limited; and the small-size ecological wetland of tradition especially sets up under the condition in the district, if the storage is improper in rainy season to deposit water, easily causes quality of water to worsen, and mosquito breeds, influences regional environment. The rainwater garden landscape effect is better, but the capability of reducing the radial flow is limited.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to above-mentioned prior art, the utility model provides a sponge city environment-friendly rainwater well, it ensures that rainwater drainage is unobstructed while furthest improves quality of water and discharges, reduces the frequency of occurrence of operation common faults such as rainwater pipeline silting up, blockking up.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a sponge city environment-friendly rainwater well, includes the well room, and rainwater grate and inspection well apron are installed at the top of well room, and the sewage interception hand-basket is installed to the below of rainwater grate, is equipped with no sand concrete permeable wall in the well room, and the outlet pipe is connected to the lateral wall of well room, be equipped with a plurality of filtration pore on the sewage interception hand-basket, the upper end of filtration pore is provided with hollow first round platform the lower extreme of filtration pore is provided with hollow second round platform, first round platform, filtration pore and second round platform link up, form rainwater passageway.
Furthermore, an elastic film is arranged at the end part of the second round table, and a liquid leakage gap is formed in the elastic film.
Furthermore, the inner walls of the well chambers on two sides of the sand-free concrete permeable wall are provided with precast block clamping grooves for fixing the sand-free concrete permeable wall.
Furthermore, the distance from the top of the sand-free concrete permeable wall to the bottom of the manhole cover plate is 30cm, and the suspended area is larger than the sectional area of the water outlet pipe.
Furthermore, the water permeability coefficient of the sand-free concrete permeable wall is 0.5 mm/s.
Has the advantages that: the utility model discloses collect the water purification link to the rainwater and adopt dual processing technology, furthest reduces water pollution, alleviates pipeline and inspection shaft operation common fault. The basket type rainwater comb and the detachable permeable retaining wall can treat rainwater by blocking, intercepting and filtering sludge, garbage and large-particle pollutants, and the basket and the sand-free concrete permeable wall can be repeatedly used for a long time or replaced, so that the operation period of the pipeline can be effectively prolonged without affecting the operation effect of the whole process.
Set up first round platform, the rainwater can be followed the open end of first round platform and flowed into in the middle of the filtration pore, and the filtration pore can directly be plugged up to solid-state rubbish by effectual avoidance of first round platform, has guaranteed that the rainwater can get into the well indoor smoothly. The second round platform prevents a part of rainwater from adhering to the lower end face of the sewage intercepting lifting basket when passing through the filtering holes. After the rainwater entered into the second round platform, because the pressure effect can pass through elastic film to the rainwater can get into in the middle of the well room, and after getting into completely, elastic film can be automatic closed, thereby has guaranteed the sealed effect of filtration pore, can avoid the peculiar smell in the well room to spill over, plays the effect of better isolated peculiar smell.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of the bottom of the dirt intercepting basket of the present invention;
reference numbers in the figures: 1. a sewage intercepting lifting basket; 1.1, a first round table; 1.2, filtering holes; 1.3, a second round table; 2. a rainwater grate; 3. a manhole cover plate; 4. a water outlet pipe; 5. a sand-free concrete permeable wall; 6. a precast block clamping groove; 7. a well chamber.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a well room 7, the top installation rainwater grate 2 of well room 7, rainwater grate 2's below is installed and is cut dirty hand-basket 1, is equipped with no sand concrete permeable wall 5 in the well room 7, and the part that 5 one side of no sand concrete permeable wall corresponds rainwater grate 6 forms the mud pit, and the opposite side forms the inspection shaft, and the top of inspection shaft is equipped with inspection shaft apron 3, and outlet pipe 4 is connected to the lateral wall of inspection shaft.
As shown in fig. 2, a plurality of filtering holes 1.2 are arranged on the sewage intercepting lifting basket 1, a hollow first circular truncated cone 1.1 is arranged at the upper end of each filtering hole 1.2, a hollow second circular truncated cone 1.3 is arranged at the lower end of each filtering hole 1.2, and the first circular truncated cone 1.1, the filtering holes 1.2 and the second circular truncated cone 1.3 are communicated to form a rainwater channel. The aperture and the opening rate of the filter holes 1.2 and the sizes of the first round table 1.1 and the first round table 1.1 are determined according to actual needs.
Preferably, an elastic film is arranged at the end of the second round table 1.3, and a leakage gap is arranged on the elastic film. The gravity of the rainwater increases the leakage gap, so that the rainwater falls into the well chamber. When no rain exists, the leakage gap is reduced due to the elastic action, so that the peculiar smell in the well chamber cannot overflow. The elastic film can be stuck to the bottom of the second round table by waterproof adhesive.
The utility model carries out double filtration to collected road surface rainwater through the rainwater grate, the sewage interception lifting basket and the sand-free concrete permeable wall and then discharges the collected road surface rainwater into the inspection well, wherein the sewage interception lifting basket can effectively carry out first sewage interception and sedimentation to the road surface rainwater and discharge the rainwater into the water collection well, and then the sand-free concrete permeable wall carries out secondary sedimentation to the rainwater treated by the sewage interception lifting basket, and the rainwater flows into the water collection branch pipe and is discharged into the inspection well after being filtered; the non-sand concrete wall is for dismantling movable barricade in the inspection shaft, build the fixed permeable wall position of prefabricated section draw-in groove through the well room by laying bricks or stones, the permeable wall top is 30cm at the bottom of the inspection shaft lid board, unsettled area is greater than receives the water branch pipe sectional area, the permeable wall coefficient of permeating water is 0.5mm/s, the wall that permeates water forms the overflow when the rainwater is too big deposits the wall, ensure that the unobstructed furthest improvement quality of water emission simultaneously of rainwater drainage, reduce the running through diseases's such as rainwater pipeline silt up, the jam emergence frequency.
The above-mentioned embodiments further describe the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
