[0037] 4) Erection of the water storage tank body 20: The water storage tank body 20 is erected in the foundation pit 10. There is a water outlet on the outer side of the water storage tank body 20, and one end of the pipeline 30 is communicated with the water outlet. The pipeline 30 and the water storage tank body 20 are arranged side by side and opposite to each other. There are a water inlet and a recovery port 21 on the top of the water storage tank body 20. A steel reinforcement cage is fixedly connected to the outer side of the water storage tank body 20;
[0038] 5) Preliminary backfilling: Backfill the soil until the height of the finally backfilled soil is flush with the top of the water storage tank body 20. When backfilling, shield the top of the water storage tank body 20 to prevent soil from backfilling into the tank body;
[0039] 6) Concrete pouring: Pour concrete into the water storage tank body 20, vibrating while pouring to ensure the compactness of the poured concrete, so that the concrete and the steel reinforcement cage are integrally formed. After pouring, cure the concrete, and then carry out subsequent construction after the concrete curing is completed;

After installation, most of the pressure of the pipeline 30 is exerted on the water storage tank body 20, the positioning cushion block 40 and the baffle 50, so that the pressure borne by the pipeline 30 is greatly reduced. Therefore, even when the pipeline 30 is in a waterless state, it is not easy to have the problem of pipe wall rupture, solving the problem that the pipeline 30 is prone to rupture when it is underground.
[0043] In construction step 2), excavation is carried out by means of manual assistance to machinery. During excavation, the surplus soil is transported away as it is dug.
[0044] In this embodiment, in construction step 3), a trench 11 for the pipeline 30 is excavated on the side wall of the foundation pit 10, and a plurality of positioning cushion blocks 40 are vertically and spacedly installed on the inner side wall of the trench 11. In this way, the positioning and installation construction of the positioning cushion block 40 can be facilitated.
[0045] In this embodiment, in construction step 4), the positioning cushion block 40 includes a clamping ring 41 and two sockets 42. The clamping ring 41 is arranged around the outer circumference of the pipeline 30 in the circumferential direction. The two sockets 42 are respectively installed on both sides of the clamping ring 41. A plurality of embedding segments 43 are provided at one end of the socket 42 facing away from the clamping ring 41. One socket 42 is inserted into the trench 11 through the embedding segments 43, and the other socket 42 is inserted into the steel reinforcement cage through the embedding segments 43.
[0046] The positioning cushion block 40 clamps and positions the pipeline 30 through the clamping ring 41, and is respectively installed in the concrete and the trench 11 through the two sockets 42 to position the position of the clamping ring 41, so that the positioning cushion block 40 can vertically clamp and position the pipeline 30 to achieve the protection of the pipeline 30.
[0047] In this embodiment, a plurality of slots for inserting the baffle 50 are formed by inward depression on the socket 42. A surrounding area is formed by the interval between the two clamping rings 41. A plurality of baffles 50 are arranged around the circumference of the surrounding area. The two vertically arranged sockets 42 are connected to the baffle 50 through the slots. A surrounding cavity 51 is formed by the enclosure of the plurality of baffles 50, and the surrounding cavity 51 is located in the surrounding area.
[0048] The socket 42 is used for the baffle 50 to be inserted. The plurality of baffles 50 are butted through the slots on the plurality of sockets 42 and enclose the surrounding area to form a surrounding cavity 51 for protecting the pipeline 30 and reducing the pressure on the pipeline 30.
[0049] In this embodiment, the pipeline 30 is located in the surrounding cavity 51, and a rubber layer is filled in the surrounding cavity 51. The rubber layer is arranged around the circumference of the pipeline 30.
[0050] The pipeline 30 can absorb impacts through the rubber elasticity in the rubber layer, reducing the damage of the pipeline 30 caused by external forces.
[0051] In this embodiment, a plurality of suspension rings 31 are provided on the outer circumference of the pipeline 30. The plurality of suspension rings 31 are arranged at intervals in sequence along the radial direction of the pipeline 30. The bottom of the suspension ring 31 abuts against the top of the clamping ring 41, and the clamping ring 41 and the suspension ring 31 are coaxially arranged.
[0052] The pipeline 30 is suspended on the clamping ring 41 by using the suspension ring 31, thereby increasing the positioning and installation of the pipeline 30.
[0053] In this embodiment, the recycling device 60 includes a moisture-preserving cotton layer 61 and a fixing frame 62. A water collecting cavity 63 is formed by downward depression on the fixing frame 62. The moisture-preserving cotton layer 61 is laid in the water collecting cavity 63. A plurality of drain ports 64 are formed at the bottom of the water collecting cavity 63. A retaining ring 65 protrudes upward from the inner side wall of the drain port 64. The retaining ring 65 is arranged to surround the circumference of the drain port 64. A water receiving hopper 66 is provided on the bottom of the fixing frame 62. The water receiving hopper 66 is communicated with the recycling port 21 of the water storage tank body 20.
[0054] The recycling device 60 receives the excess water given by the greening area through the water collecting cavity 63 in the fixing frame 62. The fixing frame 62 uses the moisture-preserving cotton layer 61 to moisturize and maintain the planting layer 80, thereby increasing the growth efficiency of the plants on the greening area. The water collecting cavity 63 recycles the excess water through a plurality of drain ports 64. The drain ports 64 block part of the water through the height of the retaining ring 65, so that the water can moisturize the moisture-preserving cotton layer 61. The retaining ring 65 can also block the gravel in the soil from clogging the drain ports 64. The water filtered from the fixing frame 62 is introduced into the water storage tank body 20 through the water receiving hopper 66.
[0055] In this embodiment, a plurality of support rods 67 protrude upward circumferentially from the top of the retaining ring 65. The bottoms of the plurality of support rods 67 are respectively abutted against the top of the retaining ring 65. The tops of the plurality of support rods 67 are connected by a support plate 68. A plurality of hollow openings 69 are formed by enclosing the retaining ring 65, the support plate 68 and the support rods 67. The hollow openings 69 are communicated with the drain ports 64. A drain valve 610 that moves up and down is provided on the retaining ring 65. The drain valve 610 blocks the drain ports 64. A plurality of floating strips 611 are arranged to surround the outer circumference of the drain valve 610. The floating strips 611 are exposed outside the hollow openings 69. The diameter of the support plate 68 is larger than the diameter of the drain valve 610. In this way, a floating space can be provided for the floating strips 611.
[0056] When the water accumulation height in the water collecting cavity 63 is higher than the retaining ring 65, the floating strips 611 are driven by the buoyancy of the excess water accumulation to drive the drain valve 610 to move towards the support plate 68. The drain valve 610 disengages from the drain ports 64, and the excess water accumulation enters the drain ports 64 from the plurality of hollow openings 69, and thus enters the water receiving hopper 66.
[0057] In this embodiment, a diversion cavity 612 communicated with the drain ports 64 is provided in the water receiving hopper 66. A diversion pipe 613 is connected to the bottom of the diversion cavity 612. The diversion pipe 613 is communicated with the recycling port 21. A high-position pipe 614 protrudes upward from the top of the diversion pipe 613 away from the recycling port 21. The high-position pipe 614 is exposed in the diversion cavity 612.
[0058] The water receiving hopper 66 receives the excess accumulated water through the diversion cavity 612. The diversion cavity 612 uses the height of the high-level pipe 614 to intercept the high-level pipe 614 a second time, thereby preventing small gravel contained in the excess accumulated water from flowing into the water storage tank body 20, achieving a filtering effect.
[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
