Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

an ecological river channel convenient to clean, refer to fig. 2, comprises a wetland bed 1, and an impermeable layer 11 and a gravel layer 12 are sequentially paved in the wetland bed 1 from bottom to top. The impermeable layer 11 is formed by tamping reinforced concrete, and after the impermeable layer 11 is dried, gravel is laid above the impermeable layer to form a gravel layer.

Referring to fig. 2, a water distribution area 2 and a water collection area 3 are dug on two opposite sides of a wetland bed 1, the inner side walls of the water distribution area 2 and the water collection area 3 are respectively piled with a side wall and a bottom wall, and concrete is coated on the inner side surfaces of the side wall and the bottom wall, so that a water channel capable of collecting water is formed.

Referring to fig. 2, a water inlet pipe 21 is arranged in the water distribution area 2, when the inner side walls of the water distribution area 2 and the water collection area 3 are piled up, a plurality of brackets 4 are respectively pre-embedded in the inner side walls of the water distribution area 2 and the water collection area 3, and hoops for fixing water pipes are welded on the brackets 4. After the water inlet pipe 21 enters the water distribution area 2, the water inlet pipe is fixed in the water distribution area 2 through the hoop on the bracket 4.

Referring to fig. 2, the water inlet pipe 21 is connected to a first water pump 211, and the first water pump 211 can pump external sewage into the water distribution region 2. When the water distribution area 2 and the water collection area 3 are piled up, the side walls of the water distribution area and the water collection area facing the wetland bed 1 are communicated with the wetland bed 1. The sewage penetrates into the gravel layer 12 and flows into the water collection area 3 through the gaps between the gravel layers 12. The sewage is filtered during its passage through the gravel layer 12, so that the water flow entering the water collection space 3 is purified.

Referring to fig. 2, a water outlet pipe 31 is arranged in the water collecting area 3, and one end of the water outlet pipe 31 extending into the water collecting area 3 is fixed in the water collecting area 3 through a hoop on the bracket 4. The second water pump 311 is connected to the water outlet pipe 31, and the second water pump 311 can convey and recycle the purified water flow in the water collecting area 3, so that the recycling efficiency of the water flow is improved.

Referring to fig. 2, the wetland bed 1 is filled with water which flows over the gravel layer 12. The planting basket 5 floats on the water flow, the planting basket 5 is made of a hollow plastic pipe, and a floating ball 51 is hung on the side wall of the planting basket 5. The planting basket 5 realizes floating on water flow through the hollow arrangement and the arrangement of the floating ball 51.

Referring to fig. 2, a soil layer 52 is laid in the planting basket 5, and in order to prevent the soil layer 52 from being entangled in the water flow and losing, a geotextile 53 is laid at the bottom of the planting basket 5, and the soil layer 52 is laid on the geotextile 53. The soil layer 52 is planted with green plants 6.

Referring to fig. 2, owing to what adopt is that showy planting basket 5 carries out green planting of planting 6, when floating rubbish impurity on rivers, rubbish impurity can not twine green root of planting 6, only can float on the surface of water, consequently when the clearance, only need plant between basket 5 salvage can, improved the convenience of clearance rubbish.

Referring to fig. 2, since the planting basket 5 floats on the water flow, the soil on the upper surface cannot absorb enough water in time, so that the soil layer 52 can absorb enough water, a diversion cotton core 54 is pre-buried in the soil layer 52, and the diversion cotton core 54 penetrates through the bottom of the planting basket 5 and enters the water flow. The water can enter the soil layer 52 along the water diversion cotton core 54, so that the soil layer 52 can be replenished with water.

Referring to fig. 2, a traveling beam 55 is connected between adjacent planting baskets 5, and an end of the traveling beam 55 is connected to the planting baskets 5 by bolts. Walking beam 55 is convenient for the staff to walk, when cleaning the floater on rivers, the staff can switch between two adjacent planting baskets 5 through walking beam 55, consequently makes the staff can clear up two rubbish of planting between the basket 5.

Referring to fig. 2, a water feeding pipe 7 is inserted into the water collecting area 3, and a pipe body of the water feeding pipe 7 entering the water collecting area 3 is fixed in the water collecting area 3 through an anchor ear. One end of the water adding pipe 7 far away from the water collecting area 3 extends into the wetland bed 1, and a water suction pump 71 is connected to the water adding pipe 7. One side of the water distribution area 2 facing the wetland bed 1 is provided with a water overflowing port 8, and the water overflowing port 8 is positioned above the gravel layer 12. The grid plate 81 is fixedly connected to the water overflowing port 8.

Referring to fig. 2, the utility model discloses in the in-service use process, the rivers after the suction pump 71 purifies in with catchment area 3 are constantly taken out to wetland bed 1 in, and the rivers in wetland bed 1 get into in the district of distributing water 2 through overflowing mouth of a river 8, get into in the district of distributing water 2 rivers get into catchment area 3 once more after the gravel layer 12 filters to this effect of having realized reciprocating utilization. Meanwhile, after the purified water enters the wetland bed 1, the original water flow in the wetland bed 1 is promoted to flow, so that the phenomenon that the water flow is stopped for a long time to form stink is reduced.

The specific implementation principle is as follows:

the sewage is sucked by the first water pump 211 and enters the water distribution area 2, and the sewage penetrates the water distribution area 2 and is immersed into the gravel layer 12. Sewage flows into the water collecting area 3 through gaps among the gravel layers 12, and in the process that the sewage passes through the gravel layers 12, large-particle impurities in the sewage are filtered.

Part of water in the water collecting area 3 is led out to other places for use through the water outlet pipe 31, the other part of water enters the wetland bed 1 through the suction of the water suction pump 71, and the purified water promotes the water flow in the wetland bed 1 to flow, so that the possibility of generating the odor phenomenon of the water quality is reduced.

The utility model discloses long-time work back, the staff walks on planting basket 5, salvages the floater in the rivers, and among the salvage process, the staff realizes through walking beam 55 that each is planted and removes between basket 5 to it is more convenient to make salvage.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
