Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of residential quarter sewage grid setting pot, be arranged on residential cell sewage exit, comprise pool wall 1, be located at water inlet pipe 5 on pool wall 1 and outlet pipe 6 and the sand setting portion 2 be located in pool wall 1 and grid portion, water inlet pipe 5, sand setting portion 2, grid portion, outlet pipe 6 set gradually water inlet pipe 5 and are connected with residential cell sewage outlet, and outlet pipe 6 is connected with municipal wastewater pipe.Water inlet pipe 5, outlet pipe 6 are equipped with rigid waterproofing wing eyelet thimble 7 with the junction of pool wall 1.
The grid setting pot water inlet pipe degree of depth is determined according to the sewage pipe of residential quarters, and mobility scale is 1.3 ~ 4.0m.The elevation difference of inlet and outlet pipe lines is 0.15m, and this is the loss of flood peak of grid setting pot.
The heavier contamination precipitations such as the ight soil in sewage, rubbish mainly get off by the effect in sand setting portion, avoid it to enter municipal wastewater pipeline and result in blockage.Effective sand setting volume in sand setting portion is defined as 30 days by house community wastewater amount, namely meets the requirement of precipitation portion compared with heavy seeds, is convenient to again residential quarters property and manages, and unlikely cleaning frequency is too high, and the comparatively heavy seeds of precipitation is regularly aspirated by mud pump truck.
Grid in order to stop retain in sewage in suspending or the bulk solid content of floating state, as waste paper, plastic products, fiber and other house refuses, enter municipal pipeline to prevent these foreign material and cause and silt up.Grid portion comprises grid 3 and grid base 4, and grid 3 one end is connected with grid base 4, and the other end is connected with pool wall 1, and grid base 4 is provided with the draw-in groove for stationary grizzly 3, and the inclination angle of grid 3 can be 65 °, also can be provided with other angle, as 60 ° etc.Owing to being arrange grid 3 in sewage, for preventing corrosion, grid 3 adopts 304 stainless steels.The component strength of grid is no more than 0.3m design by two sides water-head.
As shown in Figure 3-Figure 5, the transversely strengthening angle steel 302 that grid 3 comprises grid body 301 and is located on grid body 301, reinforce together by every 1.0m, grid body 301 is made up of many spaced perpendicular band steels 303, and the clear distance of grid adopts 20mm.These foreign material that sewage is taken both having ensured to enter municipal wastewater pipeline can not blocking pipe, makes again the cleaning work amount of residential property company control, in certain scope, to reach balance.For reducing construction costs and administrative expenses, grid adopts and manually drags for grid clearly.
Pool wall 1 and grid 3 junction are provided with installation outrigger, and be provided with pre-buried angle steel 305 in this installation outrigger, grid 3 is welded with pre-buried angle steel 305 by horizontal band steel 304, ensure the connection reliability of grid, prevent grid instability from making sewage directly enter municipal pipeline.
Pool wall 1 is by the pond body of reinforced concrete cast-in-situ, ensures the seal of grid setting pot, can guarantee that sewage can not permeate the ground, polluted underground water.
As shown in Figure 2, pool wall 1 corresponds to above sand setting portion 2 and be provided with cover plate of manhole 8, join the D400-Ф 710 steel fiber reinforced concrete cover plate that municipal administration is conventional, pool wall 1 corresponds to above grid 3 and be provided with rectangle reinforced concrete cover plate 9.In the present embodiment, rectangle reinforced concrete cover plate 9 can be provided with 4.Pool wall 1 is also provided with air-vent 10.
The present embodiment grid setting pot can be arranged on residential quarters greenbelt or Intra-cell road, owing to being sewage treatment structure, requires should be greater than 10m from residential building distance.If the requirement of 10m cannot be met apart from residential building, then breather pipe should be set and cause roof by residential building gable.
