[0029] Example

[0030] like Figures 1-5 As shown, the present invention discloses a bagged sand artificial island drainage device, including a bagged sand protective slope 1 evenly laid on the outer perimeter of the artificial island beach. In this technical solution, the slope angle of the bagged sand protective slope 1 is set at 15°-45°, and the top width is designed to be 5M-15M.

The drilling platform oil and gas facilities are set in the center of the artificial island. Several water collection wells 4 are evenly arranged on the artificial island around the oil and gas facilities. In this technical solution, the design of the water collection wells 4 can be considered to collect fresh water during rain, or not to collect fresh water during rain. If fresh water is not collected, the height of the permeable water guide strip 5 gradually decreases as it extends toward the wave wall 2, making it easier for the permeable water guide strip 5 to drain water to the outside.

[0031] On the side of the water collection well 4 closest to the oil and gas facilities, a second seepage barrier wall 6 is vertically arranged and connected end to end under the ground of the artificial island.

[0033] Specifically, the second impermeable wall 6 is further evenly laid with a plurality of second auxiliary water guide strips 9 on the side of the oil and gas facilities on the artificial island ground, the height of the end of the second auxiliary water guide strip 9 close to the oil and gas facilities is higher than the other end, and a lifting beam 10 is further arranged below the second auxiliary water guide strip 9, in the embodiment, the second auxiliary water guide strip 9 can be made of porous polyurethane macromolecular material, and the lifting beam 10 is used to make the two ends of the second auxiliary water guide strip 9 still maintain the inclination towards the water collecting well 4 after experiencing natural settlement.

[0035] Specifically, a plurality of first auxiliary water guide strips 8 are evenly arranged in a circular manner on the outside of the water collecting well 4 on the horizontal plane in the soil, one end of the first auxiliary water guide strip 8 extends to the water collecting well 4 and is used to transport water in the soil into the water collecting well 4, in the embodiment, the first auxiliary water guide strip 8 is made of porous polyurethane macromolecular material and is used to be laid in the soil to guide water, and the first impermeable wall 3 further improves the water transfer efficiency.

[0036] Specifically, the water collecting well 4 is a three-section hollow component, the bottom end and the top of the water collecting well 4 adopt water-proof concrete structure, and the middle part of the water collecting well 4 adopts water-guiding porous structure, in the embodiment, the water collecting well 4 is 5m long, 4m wide, 3m deep, and the floor is 20cm thick, the upper part 0.5m wall is made of concrete structure, the middle part 1.0m wall is made of 20cm thick marine polyurethane structure, and the lower part 3.5m is made of concrete structure, and the wall is 50cm thick.

In the embodiment, there are many oil and gas facilities on the artificial island, and the staff on the island needs to operate in various areas. When the staff moves on the island, it is inevitable to step on the gravel layer above the permeable water guide strip 5. When the gravel layer is repeatedly stepped on, the pressure in the area will be too large, and the soil will be hardened, which will cause the gap in the permeable water guide strip 5 to be filled with mud, and the water cannot be guided. The staff can sleeve the protection pipe 11 on the water guide strip in each area according to the actual needs, and then lay the gravel layer or cast the road surface on the ground.

The limiting frame 15 is embedded and sleeved on the outer wall of the protection pipe 11 and limits and fixes the protection pipe 11. In the embodiment, after the artificial island is filled, it needs to undergo a relatively long natural settlement period. When the settlement of each area of the artificial island is inconsistent, the staff needs to adjust the height of the permeable water guide strip 5 in order to drain the artificial island.

[0040] Specifically, the inner side of the permeable water guide strip 5 is further provided with a temperature and humidity detection probe 19. The temperature and humidity detection probe 19 is connected to a power supply device and a data acquisition platform on the artificial island through a cable. In the embodiment, the data is synchronized to the background, which can be more convenient for the staff to study the water flow direction of the artificial island.

[0042] Step two: establishing a second ring-shaped seepage-proof wall 6 connected at the head and tail around the oil and gas facilities in the artificial island, so that one end of the permeable water guide strip 5 is connected with the second seepage-proof wall 6 for draining water into the water collecting well 4; and laying building stones on the first seepage-proof wall 3, the permeable water guide strip 5 and the second seepage-proof wall 6 to establish a continuous and fixed filter layer.

[0043] Step three: uniformly laying a plurality of lifting beam frames 10 and second auxiliary water guide strips 9 on the inner side of the second seepage-proof wall 6, and arranging a plurality of first auxiliary water guide strips 8 on the outer side of the water collecting well 4 along the circumferential direction.

[0045] Step five: when the artificial island surface rains, the water on the inner side of the second seepage-proof wall 6 is transported to the inside of the water collecting well 4 through the permeable water guide strip 5 and the second auxiliary water guide strip 9, at this time, part of the fresh water on the inner side of the first seepage-proof wall 3 is also transported to the inside of the water collecting well 4 through the permeable water guide strip 5, but when the water level in the water collecting well 4 is too high, the water in the water collecting well 4 is transported to the outside of the wave protection wall 2 through the permeable water guide strip 5 to drain the artificial island.
