Description
Technical field
The present invention relates to stain disease pretreatment unit, and in particular to a kind of three lattice sedimentation basins for building site.
Background technology
Building site due to rain drop erosion, cleaning road surface and rinse construction waste water that earthwork car produces, mud has to pass through treatment can just enter municipal pipeline.City planting ductwork such as is directly discharged into without treatment, wherein a large amount of solid particles, mud and the chemical substance that contain will if things go on like this deposit, block, corroding city planting ductwork, normal rainwater discharge is influenceed, potential safety hazard is brought.
Although and the sedimentation basin that building site now uses can carry out certain treatment to building site waste water, because the effect of inertia intake, or water are heated up by wind-force and illumination and influenceed, easily forming short stream.This causes that the residence time of sedimentation basin internal zone dividing domain water is too short, cannot fully precipitate, and reduces deposition efficiency；Another part water retention time is long, occurs stagnating motionless slough, reduces the dischargeable capacity of sedimentation basin.Therefore the sedimentation basin structures in existing many building sites cannot efficiently reach the purpose of precipitation building site waste water for a long time, and treatment effect is not satisfactory.
The content of the invention
The purpose of the present invention is exactly that the three lattice sedimentation basins for building site that a kind of deposition efficiency is high, short stream turbulent flow phenomenon is few are provided for the defect for overcoming above-mentioned prior art to exist.
The purpose of the present invention can be achieved through the following technical solutions：A kind of three lattice sedimentation basins for building site, three described lattice sedimentation basins are located below ground level, including pool wall, the water inlet pipe being located on pool wall, outlet pipe and the twice partition wall that is located in pool wall, and the square hole for fluid circulation is equipped with per pass partition wall.
One end of the water inlet pipe is connected with building site place waste water, and the other end is located at described pool wall middle part, and sets rigid waterproofing wing eyelet thimble in the junction of water inlet pipe and pool wall；The depth of the water inlet pipe is set to 1.5~3m.
One end of the outlet pipe is connected with municipal rain pipe, and the other end is located on the pool wall relative with water inlet pipe, and sets rigid waterproofing wing eyelet thimble in the junction of outlet pipe and pool wall；The depth of described outlet pipe differs 0.15m with water inlet pipe, positioned at water inlet pipe horizontal plane lower section.
Described pool wall top sets rectangle reinforced concrete cover plate, lower section pours base plate, described pool wall depth is 3~5m, reinforced concrete cover plate can effectively close sedimentation basin and be contacted with extraneous, so that the wind-force of outside and shining upon and not interfering with waste water fluidised form in pond, avoid producing short stream, turbulent flow, avoid having a negative impact precipitation result with this.
Described pool wall, reinforced concrete cover plate, base plate are reinforced concrete cast-in-situ and form, it is ensured that the seal of sedimentation basin, it can be ensured that sewage does not penetrate into underground, polluted underground water.Meanwhile, cast-in-situ steel reinforced concrete can improve pool wall smooth degree, be conducive to fluidised form of the waste water in pond, effectively improve deposition efficiency.
Sedimentation basin is divided into three precipitation zones by the total twice of described partition wall, respectively partition wall a and partition wall b, and water inlet pipe, partition wall a, partition wall b and outlet pipe are arranged successively by current direction.
The square hole depth ratio low 0.05m of water inlet pipe depth on described partition wall a, the low 0.05m of square hole depth on square hole depth ratio partition wall a on partition wall b, the low 0.05m of square hole depth on the depth ratio partition wall b of outlet pipe.
Described water inlet pipe, two square holes, outlet pipes are staggered in the plane, in " it " shape.
Building site waste water flows into sedimentation basin after collecting from water inlet pipe, through square hole, so that in a zigzag by whole precipitation zone, solid particle is assembled in the presence of self gravitation and is deposited to bottom of pond in flow process reclaimed water.And the method for designing of lattice increased waste water flow, reduce hydraulic radius, improve flow condition, most flow into city planting ductwork through outlet pipe afterwards.
Compared with prior art, beneficial effects of the present invention are embodied in following several respects：
(1) present invention makes current in flowing in a zigzag by the square hole on partition wall, increases flow, saves the area, and is conducive to building site field course layout, improves wastewater sedimentation efficiency.
(2) three lattice sedimentation basin Stability Analysis of Structures reliability of the invention, safe.
(3) in the present invention, sediment fraction top is provided with reinforced concrete cover plate, and compared to existing technology, reinforced concrete cover plate can effectively prevent the short flow phenomenon that temperature difference that wind-force and Exposure to Sunlight cause etc. causes, so as to improve deposition efficiency.
(4) pool wall of the present invention is formed by reinforced concrete cast-in-situ, so can ensure that water does not penetrate into underground, polluted underground water.
(5) present invention in actual pilot when using, obtaining preferable achievement.

Fig. 3 is overlooking the structure diagram of the invention.
Wherein, 1 is pool wall, and 2 is rigid waterproofing wing eyelet thimble, and 3 is water inlet pipe, and 4 is precipitation zone, and 5 is partition wall, and 51 is partition wall a, and 52 is partition wall b, and 6 is reinforced concrete cover plate, and 7 is base plate, and 8 is square hole, and 9 is outlet pipe.
Specific embodiment
Embodiments of the invention are elaborated below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to following embodiments.
Embodiment 1
As shown in Figure 1, it is a kind of three lattice sedimentation basins for building site, the three lattice sedimentation basin is arranged at the wastewater outlet of building site place, including pool wall 1, the water inlet pipe 3 being located in the middle part of pool wall 1 and outlet pipe 9 and the partition wall 5 being located in pool wall 1, partition wall 5 includes partition wall a51 and partition wall b52, and water inlet pipe 3, partition wall a51, partition wall b52 and outlet pipe 9 set gradually.Partition wall 5 is provided with the guiding function that square hole 8 is realized to current.Outlet pipe 9 is connected with municipal rain pipe.Water inlet pipe 3, outlet pipe 9 are equipped with rigid waterproofing wing eyelet thimble 2 with the junction of pool wall 1.
Three lattice sedimentation basin water inlet pipe depth determine that mobility scale is 1.5~3.0m according to building site wastewater drainage pipe road.The elevation difference of inlet and outlet pipe lines is 0.15m, and partition wall a51 and partition wall b52 square hole 8 still are respectively 0.05m and 0.1m, are used to compensate the loss of flood peak with the elevation difference of water inlet pipe 3.Bottom of pond absolute altitude determines that mobility scale is 3.0~5.0m according to building site wastewater flow rate.
