Referring to fig. 1, the plane schematic diagram of the first embodiment of the ecological dam for the river channel box culvert mouth of the present invention is shown. Fig. 2 is the utility model discloses a longitudinal section of a first embodiment of an ecological dam for river course box culvert mouth. Combine fig. 1 and fig. 2 to show, the utility model is used for ecological damming of river course box culvert mouth includes:
the floating pontoon 10 is used for blocking water surface garbage, the floating pontoon 10 floats on the water surface of the box culvert outlet, and the floating pontoon 10 is arranged along the width direction of the river channel and is connected with two opposite inner walls of the river channel;
the pile rows 20 are vertically inserted into the river bottom and are oppositely arranged, and the pile rows 20 are arranged at the downstream of the buoy 10 in parallel and are connected with two opposite inner walls of the river channel;
a packing structure 30 filled between the pile rows 20; and
and the aeration equipment 40 is arranged at the bottom of the river.
Furthermore, the floating barrels are connected to two opposite inner walls of the river channel through nylon ropes and are used for intercepting water surface floaters such as dry branches, fallen leaves, floating algae, oil stains, household garbage and the like. The dam body structure is prevented from being blocked by water garbage, floaters on the water surface are concentrated, the fishing work of the water garbage is reduced, and the impact of water flow on the dam body is reduced.
In this embodiment, a single set of cylindrical pontoons is formed of an outer polyethylene layer and an inner polyurethane foam layer, with a hollow interior. A plurality of groups of buoys are connected in series through nylon ropes, each group of the buoys has a gap of 5-30mm, and two ends of each group of the buoys are fixed on two banks of a river surface. The structure can be flexibly arranged on the water surface, and has the advantages of inflation free, friction resistance, corrosion resistance and no pollution. Effectively concentrate water floater, prevent to influence follow-up technology, and be convenient for collect back centralized processing rubbish. The intercepted floating objects are manually removed at regular intervals.
The aeration apparatus 40 includes: a micro-nano aeration pipe 41 arranged at the water bottom; and a fan 42 connected to the micro-nano aeration pipe 41 and disposed on the river bank. The micro-nano aeration pipe is adopted for strong aeration. The oxygen content of the water body is improved, the reduction of the oxygen content of the water body caused by closure is relieved, and the water body deterioration is prevented. Compared with other aeration modes, the aeration device has better aeration effect and can effectively prevent the water deterioration caused by the slowing of water flow.
Further, the utility model discloses still include the protection network 21 of subsides locating the row of piles 20. The protection net 21 is a steel wire net. The steel wire mesh can isolate the filler from the water body and prevent the filler from leaking.
In this embodiment, the pile row 20 includes a plurality of wooden piles inserted at intervals at the bottom of the river, and can effectively fix and support the dam body, prevent water flow impact, do not need closure construction, and do not pollute the water body.
According to the actual conditions of river width, flow velocity and the like, pine piles are erected at intervals of 0.2-0.5m, a layer of steel wire mesh structure is arranged close to the pine piles, and the integral depth is 0.1-0.3m below the normal water level.
According to different actual water body conditions, the fillers are distributed in different planes in a layered manner, so that water body pollutants are effectively adsorbed and filtered. According to the actual conditions of river surface size, pollution degree and the like, the filler adopts a layout structure with two widths.
As the utility model discloses a preferred embodiment for an ecological dams of river course box culvert mouth, it is shown with fig. 2 to combine, and when the distance between a pair of row of piles 20 is less than a settlement distance, filler structure 30 includes: the first gravel sub-layer 31 is horizontally paved at the river bottom and filled between the protective nets 21; a first melon seed layer 32 horizontally laid on the crushed stone sublayer 31; and a first layer of rice sand 33 laid horizontally on the melon seed sheet layer 32.
In the present embodiment, the set distance is 1 m.
When the dam width is 0.5-1m, gravel directly filled on the underwater impermeable membrane is sequentially arranged from bottom to top, a plurality of groups of steel wire cages filled with melon seed pieces are erected on the gravel, and rice sand directly filled on the steel wire cages is arranged on the gravel. The whole distribution is in the layered distribution on the vertical surface.
As another preferred embodiment of the ecological dam for the river channel box culvert mouth, refer to fig. 3 and be the utility model discloses a plane schematic diagram of a second embodiment of the ecological dam for river channel box culvert mouth. Figure 4 is the utility model discloses a longitudinal section of a second embodiment of an ecological dam for river course box culvert mouth. Referring to fig. 3 and 4, when the distance between the pair of pile rows 20a is greater than a predetermined distance, the packing structure 30a includes: the second gravel sub-layer 31a is vertically filled and attached to the corresponding protective net 21 a; a second melon seed layer 32a vertically filled and attached to the corresponding second crushed stone sublayer 31 a; and a second rice sand layer 33a vertically clamped between the second melon seed sheet layers 32 a.
When the dam width is more than 1m, the pine piles at two sides face inwards, and the gravel, the multi-group steel wire cages filled with melon seed slices and the rice sand filled directly are sequentially filled. The whole distribution is in the level distribution on the horizontal plane.
The melon seed piece in intermediate level passes through steel wire cage and both sides filler separation, effectively prevents the mixing jam of filler, influences the filter effect, provides stable environment for the microorganism biofilm culturing.
The ecological dam of the utility model is 0.1-0.3m lower than the normal water level of the water body, and can effectively reduce the influence of the dam body on the water body. When the water level is higher than the dam body, water flow can normally flow through the top of the dam. When the water level is lower than the dam body, the water flow is naturally accumulated to raise the water level, and when the water level overflows the dam body and naturally falls, the water level is combined with the water body naturally percolated and filtered by the ecological dam to form the falling water natural reoxygenation effect.
The utility model discloses an ecological dam that dams for river course box culvert mouth's beneficial effect does:
the utility model discloses an adopt the flotation pontoon to float the surface of water and be used for keeping off the rubbish of establishing the surface of water. Through adopting vertical a pair of row of piles of locating the river bottom and relative setting of inserting and the middle filler structure of establishing of filling, form the ecological dam that is used for filtering river, can let the water natural circulation when high water level, can maintain the certain water level of surface of water again when low water level, and the drop aeration effect that forms has certain ecological landscape effect. Through the aeration equipment of locating the river bottom, improve the water oxygen content, alleviate the water because the reduction of water oxygen content that dams the result in prevents that the water from worsening. The problem that in the prior art, water surface garbage at the box culvert mouth is easy to accumulate in front of an ecological dam to block a dam body, sewage and garbage directly overflow the dam body, and are not effectively treated can be solved.
The present invention has been described in detail with reference to the embodiments shown in the drawings, and those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details of the embodiments should not be construed as limitations of the invention, which are intended to be covered by the following claims.
