Description

A rainwater sand trap for sponge city

Technical Field

The utility model relates to a rainwater sand trap especially relates to a rainwater sand trap that is used for sponge city that sponge municipal drainage engineering field was used for the emission of side ditch rainwater possesses simultaneously and cuts dirty, catchment, sand setting rainwater sand trap.

Background

The side ditches on the two sides of the sponge urban road mainly collect and discharge rainwater on the road surface, the road shoulder and the side slope, and rainwater scours to cause a large amount of non-point source pollution, and the side ditch rainwater runoff pollution is particularly serious. In the engineering design of traditional side ditch rainwater drainage, generally collect back direct discharge, perhaps only set up simple sediment of ordinary sand trap, lead to a large amount of pollutants still to get into rainwater pipeline system along with the rainwater, cause harmful effects to the environment.

The patent of the prior sand-setting well has simple structure and single function, can only provide a solution from a certain angle of rainwater penetration, closure, sand setting and the like, and can not completely solve the problem. The multifunctional building can simultaneously meet multiple functions, and has the advantages of expensive structure, large occupied space of the structure, complex structure, high manufacturing difficulty, no contribution to maintenance and difficult popularization.

Disclosure of Invention

In order to solve the technical problem the utility model provides a rainwater sand trap for sponge city, the purpose makes its simple structure, the cost is low, the installation and maintenance is convenient, possesses simultaneously and cuts dirty, catchments, sand setting.

For reaching the purpose the utility model relates to a rainwater sand basin for sponge city, including the well lid, the wall of a well divide into upper portion wall of a well and the lower part wall of a well, the upper portion wall of a well upper portion and the gutter intercommunication of one side, upper portion wall of a well import department at one side sets up the grid, be equipped with the rainwater discharge pipe between the lower part wall of a well top of opposite side upper portion wall of a well bottom and below, the lower part wall of a well is established on the well seat, be equipped with intermediate wall in the cavity that the lower part wall of a well and well seat enclose, separate into first well room and second well room with the cavity, first well room is the grid one side of intaking, the second well room is rainwater discharge.

The top of the middle partition wall is not higher than the pipe bottom of the rainwater drainage pipe.

The grating is a steel grating.

The well lid adopts steel grid cover plate.

The intermediate partition wall is made of water-permeable concrete.

The upper well wall is made of water-permeable concrete.

The connection part of the well wall at the lower part of the first well chamber and the second well chamber and the well seat is a round angle.

The utility model has the advantages of effect: the utility model discloses the well lid adopts steel net apron, can do the people moving walkways inlet for stom water simultaneously, effectively collects the ground rainwater. The gutter junction sets up the grid, effectively intercepts large granule suspended solid and floater in the rainwater in the gutter. The top of the middle partition wall is level with the bottom of the rainwater discharging pipe, the well chamber is divided into two grids, silt in rainwater is precipitated in the first well chamber to the maximum extent, and meanwhile, the partition wall is made of water-permeable concrete, so that rainwater can be effectively and rapidly discharged. The upper well wall above the top of the rainwater discharge pipe is made of water permeable concrete, so that accumulated water in the sand-settling well can be timely seeped out to avoid accumulated water under the condition that the drainage of the sand-settling well is not smooth. The utility model discloses rainwater sand trap, collect and cut dirty, catchment, sand setting in an organic whole, the feature of environmental protection is good, simple structure, preparation simple to operate, low cost is durable, and the engineering practicality is good, maintains simply, has extensive popularization and application prospect.

And (4) a water sand-settling well.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The device comprises a side ditch, a grid, a well cover, an upper well wall, a lower well wall, a well seat, a first well chamber, a second well chamber, a middle partition wall and a rainwater discharge pipe, wherein the side ditch is 1, the grid is 2, the well cover is 3, the upper well wall is 4, the lower well wall is 5, the well seat is 6, the first well chamber is 7, the second well chamber is 8, the middle partition wall is.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in the figure, the utility model relates to a rainwater sand basin for sponge city, including well lid 3, the wall of a well divide into upper portion wall of a well 4 and lower part wall of a well 5, 4 upper portions of the upper portion wall of a well and 1 intercommunication in side ditch of one side, 4 import departments set up grid 2 in the upper portion wall of a well 4 of a well of one side, be equipped with rainwater discharge pipe 10 between 5 tops of the lower part wall of a well of an well 4 bottom and below of the opposite side upper portion wall of a well, lower part wall of a well 5 is established on well seat 6, be equipped with intermediate wall 9 in the cavity that lower part wall of a well 5 and well seat 6 enclose, separate into first well room 7 and second well room 8 with the cavity, first well room 7 is grid 2 one side of intaking, second well room 8 is. Sediment is in the rainwater furthest's deposit in first well room, and intermediate bottom 9 adopts the preparation of water permeability concrete simultaneously, can guarantee that the rainwater is leading-in second well room 8 as early as possible, and the lower part wall of a well 5 and well seat 6 adopt the preparation of reinforced concrete, guarantee the firm and stable of sand sediment well.

The top of the middle partition wall 9 is not higher than the bottom of the rainwater drainage pipe 10.
