[0031] In this embodiment, a first sealing connection assembly 6 is provided at the connection between the water collecting base 1 and the water collecting ring 2. Specifically, the first sealing connection assembly 6 includes a positioning guide sealing ring 8, which includes a cylindrical sealing part 9 and a plurality of connecting ears 10 that protrude radially along the outer surface of the sealing part 9. The plurality of connecting ears 10 are abutted and installed between the water collecting base 1 and the water collecting ring 2, and the sealing part 9 is attached to the side wall of the water collecting base 1 and the water collecting ring 2.

[0032] The top surface of the water collection base 1 is provided with a guide post 11 that mates with each connecting ear 10 and can pass through the connecting ear 10. The water collection ring sleeve 2 is provided with a guide hole 12 for the guide post 11 to pass through. The side surfaces of the water collection base 1 and the water collection ring sleeve 2 are provided with an inwardly recessed groove 13 for the sealing part 9 to be embedded.

[0033] During installation, the guide sealing ring is first positioned and installed on the guide post 11 via the connecting ear 10. Then, the water collecting ring 2 is fitted onto the water collecting base 1. Positioning is achieved through the cooperation of the guide hole 12 and the guide post 11. The water collecting base 1 and the water collecting ring 2 can be clamped and pressed together by the outer buckle or fixed by bolts, so that the connecting ear 10 is squeezed as a whole, making it less prone to leakage. During this process, the connection gap between the water collecting base 1 and the water collecting ring 2 is covered and blocked by the sealing part 9 to prevent water leakage.

[0034] In the embodiment, the connection of the adjacent water collecting ring 2 is provided with a second sealing assembly 7.

[0035] The connecting sealing ring 14 not only plays a sealing role, but also plays a positioning and installation role. When the two water collecting rings 2 are installed, they are clamped and pressed by buckles or fixed by bolts. In the whole process, the upper water sealing ring 15 of the connecting sealing ring 14 is clamped into the lower ring 17 of the water collecting ring 2 on the upper side, the lower water sealing ring 15 of the connecting sealing ring 14 is clamped into the upper ring 16 of the water collecting ring 2 on the lower side, and the connecting sealing ring 14 as a whole will be extruded to deform.

[0036] In the embodiment, the water sealing assembly 3 comprises a water sealing hem 18 and a water sealing ring 19. The water sealing hem 18 is arranged downwardly from the lower surface of the water collecting base 1, and the water sealing ring 19 is arranged around the water sealing hem 18.

[0037] In order to improve the stability of the installation of the water sealing ring 19, the lower surface of the water collecting base 1 is provided with a water sealing groove 20 for the water sealing hem 18 to be clamped into.

[0039] When the water collecting base 1 is installed, in order to improve the waterproof performance, the water sealing hem 18 will extend into the anti-floating well and abut against the edge of the anti-floating well, and the water sealing ring 19 is used to improve the sealing performance of the water sealing hem 18. The water collecting base 1 is fixed by the fixing bolts 21. After the water collecting base 1 is fixed, the adjusting screw holes 23 can be moved downwardly in the adjusting screw holes 23 to extrude the water sealing ring 19, so that the water sealing ring 19 is deformed to improve the waterproof performance.

[0040] The working principle of this invention is as follows: When the water collection base 1 is fixed, a water sealing component 3 is provided at its bottom end. The bottom end of one of the water collection rings 2 can be detachably connected to the water collection base 1. The bottom ends of the remaining water collection rings 2 are sequentially connected to the top of the water collection rings 2 located on the lower side. The water collection base 1 and several water collection rings 2 are spliced ​​together to form a cavity 4 for water collection. When filling the anti-floating well with filter media, the water collection base 1 is fixed to the wellhead of the anti-floating well, and the number of water collection rings 2 is selected according to the actual height requirements and installed on the water collection base 1 to form a water collection cavity. This allows the water overflowing from the anti-floating well to be collected in the cavity 4, preventing the filter media from turning over with the water flow. This allows for better backfilling of the filter media. The water in the cavity 4 can be pumped out by a water pump.

[0041] During installation, to improve waterproofing performance, the water-sealing edging 18 of the water collection base 1 extends into the anti-floating well and abuts against the edge of the anti-floating well. At the same time, the sealing performance of the water-sealing edging 18 is improved by the water-sealing ring 19. The water collection base 1 is fixed by the fixing bolts 21. After the water collection base 1 is fixed, the adjustable screw hole 23 can be moved downward within the adjustable screw hole 23 to squeeze the water-sealing ring 19, causing the water-sealing ring 19 to deform and improve the waterproofing performance.

[0042] When the water collecting base 1 and the water collecting ring 2 are installed, the top surface of the water collecting base 1 is provided with a guide post 11 that cooperates with each connecting ear 10 and can pass through the connecting ear 10. The water collecting ring 2 is provided with a guide hole 12 for the guide post 11 to pass through. The side surfaces of the water collecting base 1 and the water collecting ring 2 are provided with an inwardly recessed groove 13 for the sealing part 9 to be embedded.

[0043] When installing adjacent water collection rings 2, the two water collection rings 2 are clamped together by snaps or fixed by bolts. During the process, the upper sealing ring 15 of the connecting sealing ring 14 is inserted into the lower ring 17 of the upper water collection ring 2, and the lower sealing ring 15 of the connecting sealing ring 14 is inserted into the upper ring 16 of the lower water collection ring 2. The connecting sealing ring 14 as a whole will be squeezed and deformed.

At the same time, the water sealing ring is set around the water sealing edge. The water collection base is fixed by fixing bolts. After the water collection base is fixed, the adjusting bolts can be moved downward in the adjusting screw hole to squeeze the water sealing ring, so that the water sealing ring deforms to improve the waterproof performance.

[0046] S2: Install the water collection ring sleeve: When installing the water collection base and the water collection ring sleeve, first position and install it on the guide post through the connecting ears, and then put the water collection ring sleeve on the water collection base. Positioning is achieved through the cooperation of the guide hole and the guide post. The water collection base and the water collection ring sleeve can be clamped and pressed together by the outer buckle or fixed by bolts, so that the connecting ears can be squeezed as a whole, and the connection gap between the water collection base and the water collection ring sleeve is covered and blocked by the sealing part.

[0047] S3: Water collection ring sleeve connection: When installing adjacent water collection ring sleeves, the two water collection ring sleeves are clamped and pressed together by snaps or fixed by bolts. During the process, the upper sealing ring of the connecting sealing ring is inserted into the lower ring of the upper water collection ring sleeve, and the lower sealing ring of the connecting sealing ring is inserted into the upper ring of the lower water collection ring sleeve. The entire connecting sealing ring will be squeezed and deformed.

[0048] S4: Filter media backfilling: The filter media particles are backfilled into the anti-buoyancy well. The water in the anti-buoyancy well will be squeezed and overflow from the top of the anti-buoyancy well into the cavity of the water collection structure. At this time, the dynamic water head of the backfill surface is converted into the static water head.
