Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the multifunctional ecological permeable dam comprises a dam body, a filter screen 3, a water retaining base 6, a dam base 7, a fixing pile 8, a plant layer 10 and a diversion column 13. The water retaining base 6, the dam base 7 and the fixing piles 8 which are sequentially arranged along the water flow direction of the river channel are all fixed in bottom mud of the river channel.
As shown in fig. 1 and 2, the dam body comprises a first dam 1, an impermeable layer 4 and a second dam 5. The longitudinal sections of the first dam body 1 and the second dam body 5 are both trapezoidal. The width of the bottom surface of the first dam body 1 is smaller than that of the top surface of the second dam body 5. The second dam 5 is arranged on the dam foundation 7. The first dam 1 is arranged at the top of the second dam 5. An impermeable layer 4 is arranged between the first dam body 1 and the second dam body 5. The impermeable layer 4 can prevent the water body from leaking downwards when the first dam body 1 flows through. The first dam body 1 is aligned with one side face of the second dam body 5 to form an upstream slope 2 of the dam body. The parts of the other side surfaces of the first dam body 1 and the second dam body 5 and the top surface of the second dam body 5 which are not covered by the first dam body 1 form a step-shaped backwater slope of the dam body. The backwater slope consists of a top slope section, a horizontal section and a bottom slope section which are sequentially arranged from top to bottom. The first dam body 1 and the second dam body 5 both adopt a gabion mesh structure; filter materials are filled in the first dam body 1 and the second dam body 5; the particle size of the filter material in the first dam body is larger than that of the filter material in the second dam body. The grain size of the filter material in the first dam body is 4-8 mm; the grain size of the filter material in the second dam body is 2-4 mm.
The upstream slope of dam main part is provided with filter screen 3. The filter screen 3 is a detachable filter screen. The top surface of the dam body is provided with a running water layer 12. A plurality of flow dividing columns 13 are arranged on the flowing water layer 12 at intervals. And a water blocking layer 11 is arranged on the top slope section of the backwater slope of the dam body. The water-resistant layer 11 is provided with a wave ladder 1101. The wave ladder 1101 is composed of a plurality of arc-shaped bars arranged in sequence. Each arc strip can continuously change the flow direction of water flow, and the flow distance of lengthened water flow, thereby absorbing partial kinetic energy in water flow, and achieving the effects of slowing down the flow rate of water flow, increasing the reoxygenation effect and being beautiful. The horizontal section of the dam body back slope is provided with a plant layer 10. The plant layer 10 is provided with aquatic plants, which have the functions of absorbing, adsorbing and intercepting nutritive salt, slowing down the eutrophication process and improving water quality.
As a preferred scheme, the multifunctional ecological permeable dam further comprises a movable water baffle 9. The inner side edge of the movable water baffle 9 is hinged with the top of the bottom slope section of the backwater slope of the dam body. The movable water baffle 9 is driven by a water baffle driving assembly. The water baffle driving assembly comprises a rope, a top pulley, a motor and a rope winding wheel. The top pulley and the rope winding wheel are supported on the driving frame; the driving frame is fixed in the river channel. The rope winding wheel is driven by a motor. The rope is wound around the top pulley, one end of the rope is wound on the rope winding wheel, and the other end of the rope is connected with the movable water baffle 9. The motor rotates to drive the movable water baffle 9 to turn.
The working principle of the utility model is as follows:
when the upstream water flow flows to the filter screen 3; the filter screen 3 filters out some suspended matters with large particle size.
The state of the river is divided into a dry period, a semi-dry period, a rich period and a strong rich period according to the size of water flow, wherein the water flow is increased in sequence.
And in a dry period when the water flow is slow and the water level is low, the water baffle driving assembly drives the movable water baffle 9 to overturn to a state of covering the bottom slope section of the backwater slope of the dam body. At the moment, the water body in the second dam body 5 is difficult to pass through the movable water baffle 9 and enter the downstream, so that the water storage effect is achieved; meanwhile, the water body is kept in the second dam body 5 for a long time, so that the water body restoration effect is improved.
In a half-dry period, the water baffle driving assembly drives the movable water baffle 9 to turn over to a horizontal state. At the moment, the water body enters the downstream through the second dam body 5; the particle diameter of the filter material in the second dam body 5 is smaller; the residence time of the body of water in the second dam 5 is also longer.
In the rich water period, the water flow is faster, and the water level rises to the position of the first dam body 1. At the moment, the water retaining base 6 has a buffering effect on water flow, and the impact force received by the dam body is reduced. Because the particle diameter of the filter material in the first dam body 1 is larger than that of the filter material in the second dam body 5, the first dam body 1 can effectively accelerate the passing capacity of water flow in the water-rich period. The flow velocity of the water body seeped out from the top slope section of the backwater slope of the dam body is reduced under the action of the wave ladder 1101, and the damage of water flow impact to the plant layer is reduced.
During strong rich water period, partial water flows over the dam body, the shunting column 13 has a shunting effect on the water flow, and the impact of the water flow on the plant layer is reduced together by matching with the wave ladder 1101.
