[0024] Please refer to Figures 1-3The utility model mainly provides a FBR wetland of water construction, include: wet area and set in wet area edge revetment area, and revetment area and wet area are closely connected,

[0025] Wherein, wet area includes: gravel layer 1 of laying in bottom, geotextile 2 of laying on gravel layer, gravel catchment layer 4 of laying on geotextile, volcanic rock 5 of laying on gravel catchment layer and broken stone layer 9 of laying on volcanic rock, in this embodiment, gravel layer 1 is used to slow down the water flow speed, gravel catchment layer 4 is used to intercept larger particles and carry out physical filtration, broken stone layer 9 has good drainage and prevents waterlogging and waterlogging, wherein, one end of geotextile 2 is fixed on the bank, the other end is fixed in the revetment area, and geotextile 2 can prevent gravel layer 1 from mixing with gravel catchment layer 4, and can prevent the plant root system of the bank and the revetment area from extending in, causing the damage of gravel layer 1, in addition, the anti-seepage membrane 3 is also added in the geotextile 2, wherein the anti-seepage membrane 3 can intercept larger suspended particulate matter and sediment, reduce the turbidity of water and improve water quality, volcanic rock 5 can provide a good growth environment for plants, and volcanic rock 5 can balance the pH of water.

[0026] In this embodiment, the revetment area includes: pine pile row and backfill soil 7, wherein the pine pile row is oppositely arranged as two rows, and the two rows of pine pile rows are annularly surrounded, and the backfill soil 7 is arranged inside the annular pine pile row; the pine pile row includes a plurality of uniformly arranged pine piles 6, and the pine piles 6 are all arranged at the edge of the wet area; wherein the color strip cloth 8 is arranged between the pine pile 6 and the backfill soil 7, for preventing the loss of the backfill soil 7.

[0027] In this embodiment, the pine pile is also provided with a water loss prevention mechanism; as shown in Figure 2 , Figure 3 The water loss prevention mechanism includes an air bag 13 arranged at the top end of the pine pile and an air cavity 10 arranged in the pine pile, and the top end of the inner wall of the pine pile is also provided with an air hole 12 that can communicate the air bag 13 and the air cavity 10; wherein one side of the pine pile is also provided with a water inlet 11, which is in communication with the inside of the wet area and the air cavity 10 in the pine pile respectively, so as to keep the water level of the air cavity 10 outside the wet area and inside the pine pile consistent.

[0028] In this embodiment, the air cavity 10 is also provided with a piston 14, which is in close contact with the inner wall of the air cavity 10 and slides up and down on the inner wall of the air cavity with the water flow; wherein the piston 14 is located above the water inlet, so as to facilitate the entry of the water flow and drive the piston 14 to float up, in order to avoid the piston from falling down and blocking the water inlet due to external factors, a baffle 15 can be arranged on the inner wall of the air cavity, so that the piston hovers above the water inlet (as shown in Figure 2 ).

[0029] In the embodiment, the piston 14 is made of a material with a large buoyancy coefficient, such as a foam board as the core, and the frame is wrapped with a wooden board.

[0030] The principle of the scheme is that the operator drives the pine pile 6 into the soil, encloses the area to be made into a wetland, and then nails a row of pine piles 6 inside, fills the backfill soil 7 between the two rows of pine piles 6, so that the operator can stand on the backfill soil 7 to construct the wetland. When the wetland construction is completed, the backfill soil 7 area is planted with trees to strengthen the stability of the wetland edge and prevent water loss.

[0031] When the wetland encounters crustal movement or tides, the water level is prone to fluctuation, which is easy to make the water flow out of the pine pile 6, resulting in water loss of the wetland and imbalance of the wetland ecology. When the water level fluctuates, the air cavity 10 is connected with the inside of the wetland, according to the principle of the communicating vessel, the water level in the air cavity 10 will also rise, at this time, the piston 14 rises due to the buoyancy of the water, and the gas in the air cavity 10 is sent to the air bag 13, the air bag 13 is inflated and becomes high, forming the air bag 13 wall, thereby blocking the water flow (as shown in Figure 3 ).

[0032] It should be noted that the utility model has the advantages of simple structure and convenient operation, which can not only effectively improve the purification effect of the artificial wetland on the sewage, but also fix a plurality of pine piles in the wetland and then fill the backfill soil, so that the operator can stand on the backfill soil to construct, solving the problem that the wetland construction cannot be carried out on the water.
