Abstract
The utility model relates to a grit chamber structure, in particular to a grit chamber structure convenient for dredging box culverts and improving water quality. The method is suitable for the design of buildings with box culvert outlets and open channels or box culverts intersected, and can be widely applied to the technical field of water transportation and hydraulic engineering. The technical scheme adopted by the utility model is as follows: the utility model provides a grit chamber structure which characterized in that: the sand basin that sets up in long distance box culvert middle part or box culvert export has, is equipped with the partition wall that separates a plurality of continuous rivers passageway with the sand basin in the sand basin, and the perpendicular rivers direction of partition wall is fixed in the sand basin bottom of the pool, and one side and the sand basin lateral wall of every partition wall meet, leave certain interval between opposite side and the sand basin lateral wall. The utility model provides a water tank design scheme which not only has a sand setting function, but also can improve water quality, namely, a sand setting tank structure is arranged in the middle of a long-distance box culvert, or a sand setting tank structure is arranged at an outlet of the box culvert, so that the problems of box culvert water quality, sediment deposition and the like are solved.
Description
Technical Field
The utility model relates to a grit chamber structure, in particular to a grit chamber structure convenient for box culvert dredging and improving water quality. The method is suitable for the design of buildings with box culvert outlets and open channels or box culverts intersected, and can be widely applied to the technical field of water transportation and hydraulic engineering.
Background
The urban box culvert is usually not dredged for a long time and gradually becomes shallow and narrow, water flow is not smooth, industrial and domestic sewage flows into the box culvert, and the safety of an urban drainage system and the water environmental safety are influenced. Under the general condition, long distance box culvert or box culvert export directly link up the open channel, and dry season or initial stage rainwater all directly arrange into the open channel, because of the difficult, the interior water quality of box culvert of long distance box culvert is relatively poor, the easy siltation silt scheduling problem of box culvert content, so for box culvert desilting, improve box culvert water quality and hold back partly silt, it is the problem of treating urgently to find a structural design scheme that can be convenient for desilting, sand setting and provide improvement quality of water.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: to above-mentioned problem, provide a grit chamber structure with improve quality of water, sand setting function, combine grit chamber and purification tank in the box culvert design to box culvert desilting, improvement box culvert quality of water and hold back partly silt conveniently.
The technical scheme adopted by the utility model is as follows: the utility model provides a grit chamber structure which characterized in that: the sand basin that sets up in long distance box culvert middle part or box culvert export has, is equipped with the partition wall that separates a plurality of continuous rivers passageway with the sand basin in the sand basin, and the perpendicular rivers direction of partition wall is fixed in the sand basin bottom of the pool, and one side and the sand basin lateral wall of every partition wall meet, leave certain interval between opposite side and the sand basin lateral wall.
The bottom elevation of the grit chamber is lower than the bottom elevation of the box culvert.
The grit chamber is a square water tank structure formed by a vertical wall structure, the bottom of the grit chamber extends horizontally, and the overall dimension is not limited under the requirement of meeting the structural safety.
The grit chamber is connected with a downstream open channel or box culvert.
The grit chamber is of a reinforced concrete structure formed by adopting concrete cast-in-place construction.
The utility model has the beneficial effects that: the utility model provides a water pool design scheme which not only has a sand setting function, but also can improve water quality, namely, a sand setting pool structure is arranged in the middle of a long-distance box culvert, or a sand setting pool structure is arranged at an outlet of the box culvert, so that the problems of box culvert water quality, sediment deposition and the like are improved; according to the utility model, the plurality of partition walls are arranged in the grit chamber, so that the water flow speed is slowed down, and sediment particles in a water body are deposited in the grit chamber; the bottom plate of the grit chamber is lower than the bottom of the box culvert, so that a water tank is formed, and after the incoming water of the box culvert enters the water tank and stands still, the incoming water overflows (clean water) to a downstream open channel or the box culvert.
Drawings
Fig. 1 is a schematic structural diagram of the embodiment.
Detailed Description
As shown in fig. 1, this embodiment is a grit chamber structure convenient to box culvert desilting, improvement quality of water, sets up in long distance box culvert middle part or box culvert export, is applicable to in the design of box culvert export and open channel or the crossing building of box culvert, can wide application in water transportation, hydraulic engineering technical field.
In this embodiment, the grit chamber is square, is formed by reinforced concrete pouring, and the bottom elevation of grit chamber is less than the bottom elevation of box culvert. The water storage tank is provided with an upper side vertical wall I1, a lower side vertical wall II2, a left side vertical wall II2 and a right side vertical wall II 353, has the functions of water retaining and water storage, water in a dry period is stored in the water tank, and incoming water overflows to a downstream river channel (namely a swimming open channel or a box culvert) after standing, so that the water quality can be improved; be equipped with a plurality of partition walls 4 in the grit chamber, separate into a plurality of continuous rivers passageways with the grit chamber, have the adjustment rivers flow direction, the function of interception silt, the perpendicular rivers direction of partition wall 4 is fixed in the rectangle bottom plate 3 of grit chamber, if wherein partition wall 4 one side and the left side of grit chamber found wall II2 and meet, the opposite side and the right side stand to leave certain interval between the wall II2, another partition wall 4 adjacent with this partition wall then stands wall II2 with the right side of grit chamber and meets, its opposite side and left side stand to leave certain interval between the wall II 2.
Different projects of this embodiment require different to the size of grit chamber, and cast in situ should accomplish according to the design drawing.
Claims (5)
