Description

Sponge city sewage interception anti-reflux overflow well

Technical Field

The utility model relates to an overflow well structure, especially a sponge city cuts dirty anti-current overflow well.

Background

The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be also called as a water elasticity city. The international general term is "low impact development of rainwater system construction", which absorbs, stores, seeps water, purifies water when raining, and "releases" and utilizes the stored water when necessary.

The construction of sponge cities requires the existence of sponge bodies. The city 'sponge' includes water systems such as rivers, lakes and ponds, and city supporting facilities such as greenbelts, gardens and permeable pavements. Rainwater seeps, is stored in a storage way, is purified and recycled through the sponges, and finally the residual runoff is discharged outside through a pipe network and a pump station, so that the standard of an urban drainage system can be effectively improved, and the pressure of urban inland inundation is relieved. Under the sponge city is built, the overflow well obtains the wide application, but current overflow well is not good to the filter effect of rainwater, causes the overflow well jam very easily, and each part of overflow well can not dismantle and take out, is unfavorable for the cleaing away of rainwater debris.

Disclosure of Invention

An object of the utility model is to provide a sponge city cuts dirty anti-reflux overflow well. The rainwater filtering effect is improved, the filtering box can be integrally taken out, and rainwater sundries filtered in the filtering box can be taken out more conveniently.

The technical scheme of the utility model: the utility model provides a sponge city cuts dirty anti-reflux overflow well, including the overflow well body, before the inner chamber of overflow well body, be equipped with the location arch on the back lateral wall, a left side, be equipped with vertical arch on the right side wall, its bottom is equipped with the rectangle leak, be equipped with the apopore on the lateral wall, the rose box has been put into in the inner chamber of overflow well body, the rose box top outside is equipped with the joint in the protruding department that articulates of location, articulate and be equipped with the slip connection opening with vertical arch slip connection in the arch, the inner chamber upper portion of rose box is equipped with funnel frame, the bottom plate and/or the bottom of rose box all are equipped with the filtration pore all around, still including placing the rainwater grate plate at the rose box top, the rainwater grate plate supports on vertical arch, rainwater grate plate surface is equipped with.

In the foregoing sponge city sewage interception anti-reflux overflow well, a plugging port is arranged on the sidewall of the overflow well body between the bottom of the filter box and the rectangular leakage port, a permeable layer frame is placed in the plugging port, and a permeable layer is arranged in the permeable layer frame.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

The embodiment of the utility model provides a: a sponge city sewage interception anti-reflux overflow well is shown in the attached figure 1-2 and comprises an overflow well body 8, positioning protrusions 15 which are integrally formed with the overflow well body 8 and used for supporting a filter box 4 are arranged on the front side wall and the rear side wall of an inner cavity of the overflow well body 8, vertical protrusions 16 which are integrally formed with the overflow well body 8 are further arranged on the left side wall and the right side wall of the inner cavity of the overflow well body, and 1 rectangular leakage opening 11 is formed in the bottom of the overflow well body 8. Put into in the inner chamber of overflow well body 8 and had rose box 4, the 4 top outsides of rose box are equipped with to the outside back of expanding of following, but the joint is at the protruding 15 department that articulate arch 6 in location, articulate and be equipped with the slip opening 17 with vertical protruding 16 slip on protruding 6, the inner chamber upper portion of rose box 4 is equipped with funnel frame 18, the bottom plate and/or the bottom of rose box 4 all are equipped with filtration pore 5 all around, still including 1 rainwater grate plate 1 of placing at rose box 4 top, 1 bottom sprag of rainwater grate plate is on vertical arch 16, rainwater grate plate 1 surface is equipped with the even interval rectangle open slot 3 that sets up of multichannel.

The working principle is as follows: the rainwater falls through the side edge of the rainwater grate plate 1 or the rectangular open slot 3, and at the moment, the rainwater grate plate 1 primarily intercepts larger sundries in the rainwater. After the rainwater falls to the funnel frame 18 on the upper portion of the inner cavity of the filter box 4, the rainwater falls via the middle of the inner cavity of the filter box 4 under the flow guiding effect of the funnel frame 18, and because the four side edges and the bottom of the filter box 4 are provided with the filter holes 5, the rainwater falls to the inside of the overflow well body 8 after the secondary filtration of the filter holes 5 and is discharged via the rectangular leakage opening 11 at the bottom.

Because the hanging projection 6 is hung on the transverse positioning projection 15, the left side and the right side of the hanging projection 6 are provided with sliding connection openings 17 which are used for sliding connection with the vertical projections 16, and thus, after the filter box 4 is installed, the filter box 4 is firmly and stably fixed. After a certain amount of filter substances are deposited in the filter box 4, the rainwater grate plate 1 is taken out, the filter box 4 can be taken out, the filter substances in the filter box are removed, and the filter box can be continuously used after being put back.

The side wall of the overflow well body 8 between the bottom of the filter box 4 and the rectangular leakage opening 11 is provided with a plug opening 10, a permeable layer frame 13 is placed in the plug opening 10, and a permeable layer 12 is arranged in the permeable layer frame 13. The rainwater falls to the inside of overflow well body 8 after the secondary filtration of filtering hole 5, then on drippage to permeable formation frame 13, filters again via permeable formation 12, and the rainwater after the filtration sees through permeable formation 12 and finally discharges from its below rectangle leak 11.

Because the anterior downside of overflow well body 8 is equipped with interface 10 that is used for pegging graft infiltration layer frame 13 for after overflow well body 8 is whole takes out, take out infiltration layer frame 13 very easily, conveniently change it, and also be favorable to simultaneously 8 inside rainwater debris of overflow well body to spill via rectangle leak orifice 11.

The permeable layer frame 13 is provided with a buckle groove 14 at the front part, and the permeable layer frame 13 can be conveniently pulled out by holding the buckle groove 14.

Handles 19 are welded at the front and rear parts of the upper end of the hanging projection 6, so that the filter box 4 can be taken out conveniently.

Clamping grooves 2 are formed in the left side and the right side of the bottom surface of the rainwater grate plate 1. The clamping groove 2 is used for being matched with the vertical protrusions 16, one is used for positioning the rainwater grate plate 1, and after the vertical protrusions 16 are clamped into the clamping groove 2, the surface of the rainwater grate plate 1 can be parallel and level to the surface of the overflow well body 8.

Be equipped with apopore 9 on the 8 lateral walls of overflow well body, apopore 9 department threaded connection has threaded drain pipe 20, and in the rainwater filtration infiltration process, the rainwater of not in time permeating can arrange to secret drainage channel via the threaded drain pipe 20 of apopore 9 department.

The upper end of overflow well body 8 is equipped with rather than integrated into one piece and outside along the location chimb 7 of exhibition, in the installation, will fix a position 7 joints of chimb on the step of installation gallery to guarantee 8 surfaces of overflow well body and ground parallel and level.
