Abstract

The utility model discloses a shunt type rainwater drainage port tail end trash holding and sand subsiding well. The shunt type rainwater drainage port tail end trash holding and sand subsiding well comprises a bottom board, a well base, a grate, a downflow weir and a well cover plate. The well base is of a square structure and is laid on the bottom board, one surface of the well base is connected with a water inlet pipe, and the other surface is connected with a water outlet pipe; the enclosed space of the well seat forms a sand subsiding chamber, the grate is arranged in the middle of the sand subsiding chamber, and the downflow weir is arranged at the top of the grate; the well cover plate is arranged at the top end of the well base. The shunt type rainwater drainage port tail end trash holding and sand subsiding well can reduce the pollution of solid substance in rainwater to surrounding water environment.

Description

Segregation system storm-water drainage mouth end blocks dirty catch-basin

Technical field

The utility model relates to drainage works field, and especially a kind of segregation system storm-water drainage mouth end blocks dirty catch-basin.

Background technology

In Process of Urbanization Construction process, rainfall runoff washes away the pollution of area source causing on ground has become one of main source of water pollution, has aggravated the deterioration of environment water.In current traditional rainwater engineering design, after road, block rainwater-collecting, all directly arrange river, without any cutting dirty measure.Along with the attention of people to water environment protection, in the urgent need to rethinking planning and the design of storm-water system.

Utility model content

The purpose of this utility model is to provide a kind of segregation system storm-water drainage mouth end to block dirty catch-basin.

What the utility model solved is in existing rain engineering of water treatment, can not effectively cut down the problem of rainwater to the pollution of surrounding enviroment.

The technical scheme that the utility model solves its technical problem employing is: the utility model comprises base plate, well seat, grid, overflow weir and manhole cover plate, described well seat is that square structure is built on base plate, on a face of well seat, connect water inlet pipe, on another relative face, connect outlet pipe; The space that described well seat surrounds forms a sand setting chamber, and grid is located at the centre of sand setting chamber, and overflow weir is located at the top of grid, and described manhole cover plate is located at the top of well seat.

The beneficial effects of the utility model are: by the bottomed and simple and easy dirty grid that blocks is set, can effectively cut down the solid pollutant in rainwater, protection water environment.By overflow weir is set, storm-water drainage while not affecting heavy rain.The design of stealthy cover plate does not have negative effect to surrounding landscape in addition.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model comprises base plate 12, well seat 11, grid 2, overflow weir 3 and manhole cover plate 6.

Well seat 11 is built on base plate for square structure, on 11 1 faces of well seat, connects water inlet pipe 1, on another relative face, connects outlet pipe 4.The space that well seat 11 surrounds forms a sand setting chamber 5, and grid 2 is located at the centre of sand setting chamber 5, and overflow weir 3 is located at the top of grid 2.Rainwater enters into sand setting chamber 5 by water inlet pipe 1, then through simple and easy grid 2 interception floating thing sand settings, the rainwater after purification enters river course by outlet pipe 4.If floating thing is more in rainwater, grid 2 gaps are stopped, maintenance workman is cleaning in time not, and rainwater can be discharged by overflow weir 3 tops, does not affect draining.

Manhole cover plate 6 is located at the top of well seat, catch-basin of the present utility model needs periodic cleaning rubbish, therefore need the manhole cover plate 6 can be movable, in order to make this block dirty catch-basin, do not affect landscape effect, manhole cover plate 6 is stealthy cover plate, is provided with the space 7 of planting plants in manhole cover plate 6, and space 7 is interior can settle grass planting basin, be used for planting flowers and plants, and the environment coordination of periphery.

As shown in Figure 4, grid 2 comprises stainless steel cloth 9, channel-section steel 10 and reinforcing bar 8; Channel-section steel 10 and reinforcing bar 8 are embedded in well by being welded and fixed rear integral body, and stainless steel cloth 9 assigns into channel-section steel 10Nei， upper end and is provided with handle, facilitate stainless steel cloth 9 to take out and cleaning.
