Description
Technical Field
The utility model belongs to the technical field of the hydraulic engineering technique and specifically relates to a novel ecological barrage device is related to.
Background
In natural river channels, when upstream river flows to downstream, most of the current river channels are influenced by sand extraction, river channels are cut downwards, the channel depth is deep, longitudinal slopes are gentle, most of the current river channels can only retain water through a single barrage or build ecological subsurface flow wetland, but the barrage can not retain water and build the ecological subsurface flow wetland simultaneously, and the double effects of flood control and good ecological benefit can not be achieved simultaneously, so that a novel ecological barrage device needs to be designed.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at prior art's not enough, provide a novel ecological barrage device, divide the barrage retaining water and the wetland purification water and merge, accomplish that flood control influences little and ecological profitable dual efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel ecological barrage device, includes wetland purification unit and retaining dam, the retaining dam is located wetland purification unit's low reaches, wetland purification unit from the top down includes aquatic plant, filter bed and prevention of seepage geomembrane in proper order, the filter bed includes from the top down first cobble layer that sets gradually, plants soil layer and second cobble layer, the shape of retaining dam is "step" form, be equipped with the infiltration pipe in the second cobble layer, the infiltration pipe runs through the retaining dam, just the exit end of infiltration pipe stretches into in the retaining pond that the retaining dam formed.
Furthermore, a control gate is arranged at the outlet end of the seepage pipe.
Further, the aquatic plants are planted on the outer surface of the first pebble layer.
Furthermore, the wetland purification unit is arranged on a main river channel of a river channel.
Further, the thickness of the second pebble layer is larger than that of the planting soil, and the thickness of the planting soil is larger than that of the first pebble layer.
The utility model has the advantages that:
1. the utility model provides a novel ecological barrage device, wetland purification unit set up at main river channel, and during the manger plate dam miniflow manger plate, rivers were downward through aquatic plant root system, and partial pollutant is adsorbed and is absorbed by aquatic plant root system, through microbial decomposition, can realize the whole water purification of normal flow, and the water after the purification passes through the infiltration pipe and arranges in the retaining pond to the manger plate dam formation in low reaches, accomplishes that the flood control influences little and ecological good dual efficiency of benefit, possesses general practicality and commonality.
2. The shape of the retaining dam of the utility model adopts the design of steps, the water body not only ensures the stable water flow, but also realizes the natural aeration function of the water body. The control gate arranged at the outlet of the infiltration pipe is convenient for adjusting the water flow of the infiltration pipe and ensures that the purification unit rechecks normally.
Drawings
Fig. 1 is a schematic structural view of the novel ecological barrage device of the present invention.
In the figure: the water seepage control system comprises a water retaining dam 1, a filter bed 2, a hydrophyte 3, an anti-seepage geomembrane 4, a water seepage pipe 5, a first pebble layer 6, a planting soil layer 7, a planting soil layer 8 and a second pebble layer.
Detailed Description
The invention is further described with reference to the following figures and examples.
Examples
As shown in fig. 1, a novel ecological barrage device comprises a wetland purification unit and a retaining dam 1, wherein: the wetland purification unit sets up on the main river channel of natural river course, retaining dam 1 is located the low reaches of wetland purification unit, wetland purification unit includes aquatic plant 3, filter bed 2 and prevention of seepage geomembrane 4 from top to bottom in proper order, the shape of retaining dam sets to "step" form, the retaining dam passes through the manger plate and forms the cistern.
Wherein: the anti-seepage geomembrane 4 is an anti-seepage film and is used for preventing river water from further permeating downwards after passing through the filter bed 2, the filter bed 2 comprises a first pebble layer 6, a planting soil layer 7 and a second pebble layer 8, in the concrete implementation, after the anti-seepage geomembrane 4 is paved, the second pebble layer 8 is paved from bottom to top in sequence, the second pebble layer 8 is uniformly paved to 70cm thick by adopting pebbles with the particle size of 20-40mm, the planting soil layer 7 is paved to 30cm thick by adopting planting soil, and the first pebble layer 6 is paved to 20 cm thick by adopting pebbles with the particle size of 10-20 mm. The thickness of the second pebble layer is larger than that of the planting soil, and the thickness of the planting soil is larger than that of the first pebble layer. The aquatic plants 3 are planted on the outer surface of the first pebble layer 6.
Be equipped with in the second cobble layer 8 and ooze tub 5, the entry end that oozes tub 5 is located in the second cobble layer 8, ooze tub 5 runs through retaining dam 1, just the exit end that oozes tub 5 stretches into in the retaining pond that retaining dam formed, ooze tub 5's exit end be equipped with convenient control gate (not shown in the figure), adjust oozing tub rivers size.
The novel ecological barrage device has the working process that:
the main river channel flows to the downstream, and when the retaining dam blocks water, river water seeps to the filter bed from the surface of the wetland purification unit, and through the roots of the aquatic plants, the roots of the aquatic plants adsorb water pollutants, so that all water purification with normal flow can be realized, then the purified water enters from the inlet end of the seepage pipe 5, the seepage pipe 5 penetrates through the dam body of the retaining dam, the water flow is ensured to flow into the bottom and flow out from the outlet end of the seepage pipe 5, and the size of the water flow of the seepage pipe is adjusted through the control gate.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
