[0002] Rainwater storage pools are important components of urban drainage systems. They are used to temporarily store rainwater, especially in the initial stage of rainfall, to reduce the pressure on the urban drainage system caused by rainwater runoff, control floods, and reduce pollution brought by initial rainwater. In addition, the construction and management of rainwater storage pools play an important role in improving the regional water environment and enhancing the drainage system capacity. Many places are actively planning and constructing rainwater storage pools to improve the service level of urban drainage facilities and the ability to treat initial rainwater.

[0003] CN214363988U discloses an environment-friendly deep foundation pit rainwater storage pool. When sudden heavy rainfall occurs, the deep foundation pit rainwater storage pool can temporarily store rainwater and gradually drain it through the municipal pipe network after the peak rainfall period, thus relieving the pressure on the municipal drainage system in the face of heavy rainfall and improving the flood resistance ability of the city.

[0045] Example 1

[0046] A hidden and retractable rainwater storage pool, which includes a plurality of jacking components 1 arranged underground. As Figure 1-2 shown, each jacking component 1 includes a jacking component main body 11 and a telescopic rod 12 that is telescopically arranged on the jacking component main body 11 and can extend out of the ground. A waterproof member 2 is detachably installed between adjacent telescopic rods 12 that extend out of the ground. A plurality of telescopic rods 12 and waterproof members 2 are sequentially connected to form an annular rainwater storage pool 3. A sealing component 4 is also provided underground for sealing the telescopic rod 12 to prevent rainwater leakage during rainfall.

[0047] When rainfall is about to occur, start the jacking component 1 to make the telescopic rod 12 extend out of the ground, and install the waterproof member 2 between adjacent telescopic rods 12. After all the waterproof members 2 are installed, a temporary rainwater storage pool 3 can be formed to collect rainwater. When the rainfall stops, after the rainwater gravitates and drains into the urban rainwater system, disassemble the waterproof member 2, and retract the telescopic rod 12 underground, then a temporary rainwater storage process can be completed. The jacking component 1 in this embodiment can be selected as a conventional hydraulic cylinder, and the waterproof member 2 can be selected as a common waterproof board.

[0048] Example 2

[0049] A hidden and retractable rainwater storage pool, which includes a plurality of jacking components 1 arranged underground.

A waterproof member 2 is detachably installed between adjacent telescopic rods 12 that extend out of the ground. A plurality of telescopic rods 12 and waterproof members 2 are sequentially connected to form an annular rainwater storage pool 3. A sealing component 4 is also provided underground for sealing the telescopic rod 12 to prevent rainwater leakage during rainfall.

[0050] The jacking component 1 in this embodiment is independently arranged in a foundation pit underground, and a hole for the telescopic rod 12 to extend out is opened on the ground. The jacking component 1 in this embodiment can be selected as a conventional hydraulic cylinder, the jacking component main body 11 is the cylinder body of the hydraulic cylinder, and the telescopic rod 12 is the piston rod of the hydraulic cylinder.

[0051] The waterproof member 2 in this embodiment includes a waterproof main body 21 and clamping strips 22 arranged at both ends of the waterproof main body 21. The telescopic rod 12 is axially provided with two clamping grooves 121, and the clamping grooves 121 are both hollow cylindrical structures. The clamping grooves 121 are respectively adapted to the clamping strips 22 of adjacent waterproof main bodies 21, and the clamping strips 22 are also cylindrical structures. Through the cooperation of the clamping grooves 121 and the clamping strips 22, the detachable installation of the waterproof member 2 and the telescopic rod 12 can be realized. The bottom surface of the clamping strip 22 is flush with the bottom surface of the waterproof main body 21, which can greatly reduce rainwater leakage.

[0052] As Figure 3-4As shown, in order to further reduce rainwater leakage at the connection between the waterproof member 2 and the telescopic rod 12, the telescopic rod 12 of this embodiment is radially provided with a restraint notch 122 communicating with the clamping groove 121. The restraint notch 122 penetrates along the axial direction of the telescopic rod 12, and the thickness of the restraint notch 122 is adapted to the thickness of the waterproof main body 21. During use, part of the waterproof main body 21 can be clamped in the restraint notch 122, which can greatly reduce rainwater leakage at the connection between the waterproof member 2 and the telescopic rod 12. The waterproof member 2 of this embodiment is preferably a waterproof plate.

[0054] A hidden and retractable rainwater storage pool, which includes a plurality of jacking assemblies 1 arranged underground. Each jacking assembly 1 includes a jacking assembly main body 11 and a telescopic rod 12 that is telescopically arranged on the jacking assembly main body 11 and can extend out of the ground. A waterproof member 2 is detachably installed between adjacent telescopic rods 12 that extend out of the ground. A plurality of telescopic rods 12 and waterproof members 2 are connected in sequence to form an annular rainwater storage pool 3. There is also a sealing assembly 4 provided underground for sealing the telescopic rod 12 to prevent rainwater leakage during rainfall.

[0055] As Figure 5 As shown, in order to improve the stability of the waterproof member 2 when storing and storing rainwater, a support assembly 5 is installed between the waterproof member 2 and the ground.

[0056] Embodiment 4

[0057] A hidden and retractable rainwater storage pool, which includes a plurality of jacking assemblies 1 arranged underground. Each jacking assembly 1 includes a jacking assembly main body 11 and a telescopic rod 12 that is telescopically arranged on the jacking assembly main body 11 and can extend out of the ground. A waterproof member 2 is detachably installed between adjacent telescopic rods 12 that extend out of the ground. A plurality of telescopic rods 12 and waterproof members 2 are connected in sequence to form an annular rainwater storage pool 3. There is also a sealing assembly 4 provided underground for sealing the telescopic rod 12 to prevent rainwater leakage during rainfall.

[0058] In order to reduce the influence of rainwater leakage on the normal operation of the jacking assembly main body 11, the sealing assembly 4 of this embodiment includes a first sealing member 41 and a driving member 42 that can drive the first sealing member 41 to horizontally move to abut against the telescopic rod 12. The driving member 42 can be a telescopic cylinder, and the cylinder body of the telescopic cylinder is fixed in the underground foundation pit and can be flexibly set according to geographical conditions. As Figure 6As shown in the figure, on the side of the first seal 41 close to the telescopic rod 12, a semi-circular sealing area is provided, and the diameter of the sealing area is the same as the diameter of the telescopic rod 12. When sealing is required, the telescopic cylinder is activated, and the piston rods of the telescopic cylinders symmetrically arranged on both sides of the main body 11 of the lifting assembly drive the first seal 41 to approach until it abuts against the telescopic rod 12. The two semi-circular sealing areas are combined to seal the telescopic rod 12 to prevent rainwater from leaking further.

[0059] To reduce the impact of rainwater leakage on the normal operation of the driving member 42, in this embodiment, a second seal 43 is provided between the telescopic part of the driving member 42 and the ground, which can effectively prevent rainwater leakage within the telescopic movement range. Both the first seal 41 and the second seal 43 in this embodiment are made of waterproof rubber strips. Both the lifting assembly 1 and the driving member 42 in this embodiment are connected to the PLC control system and can operate uniformly under the control of the PLC control system.

[0060] As Figure 7 shown in the figure, when there is no rainfall, the lifting assembly 1 is located in the underground foundation pit, the telescopic rod 12 is retracted, and the sealing assembly 4 is not enabled. When it is about to rain, the control system controls the operation of the lifting assembly 1 to extend the telescopic rod 12 out of the ground, and installs the waterproof member 2 between adjacent telescopic rods 12, finally forming a polygonal temporary rainwater storage pool 3 for collecting rainwater. At this time, the control system controls the horizontal movement of the piston rods of the telescopic cylinders on both sides, driving the two first seals 41 to approach the telescopic rod 12 until they abut against the telescopic rod 12 to form a seal, preventing rainwater leakage from affecting the operation of the lifting assembly 1. When the rainfall stops, after the rainwater flows into the urban rainwater system by gravity, the waterproof member 2 is disassembled, and the control system controls the telescopic rod 12 to retract underground, thus completing a temporary rainwater storage process.

[0061] Embodiment 5

[0062] A hidden and retractable rainwater storage pool, which includes a plurality of lifting assemblies 1 arranged underground. Each lifting assembly 1 includes a main body 11 of the lifting assembly and a telescopic rod 12 that is telescopically arranged on the main body 11 of the lifting assembly and can extend out of the ground. A waterproof member 2 is detachably installed between adjacent telescopic rods 12 that extend out of the ground, and a plurality of telescopic rods 12 and waterproof members 2 are connected in sequence to form an annular rainwater storage pool 3. There is also a sealing assembly 4 underground for sealing the telescopic rod 12 to prevent rainwater leakage during rainfall.

[0063] The difference from Embodiment 4 is that, as Figure 8 shown in the figure, the sealing assembly 4 in this embodiment is an annular inflatable airbag, and the telescopic rod 12 can pass through the hollow part in the middle of the inflatable airbag and extend out of the ground. During rainfall, after the telescopic rod 12 extends out of the ground, the inflatable airbag can be inflated to seal the underground part of the telescopic rod 12, greatly reducing the impact of rainwater leakage on the lifting assembly 1.

A waterproof member 2 is detachably installed between adjacent telescopic rods 12 extending out of the ground. The plurality of telescopic rods 12 and the waterproof member 2 are connected in sequence to form an annular rainwater storage pool 3.

[0066] In order to improve the waterproof effect of the waterproof member 2 and reduce the seepage of rainwater in the rainwater storage pool 3 to the outside, a plurality of waterproof bags are arranged between the waterproof member 2 and the ground. The waterproof bags are closely arranged along the outer contour of the rainwater storage pool 3.
