Description

Technical Field

[0001] The present invention relates to the technical field of rainwater collection, and in particular to a road surface rainwater collection system. Background Art

[0002] Roadside rainwater harvesting is a sustainable water resource management approach that uses systematic technical means to collect, store, and utilize road runoff. Polyethylene (PP) modular pools are a newly emerging rainwater collection pond design, primarily used for rainwater regulation, storage, and reuse in sponge city construction and rainwater comprehensive utilization projects. PP modular pools are constructed using PP modules as the pool's framework, based on water storage requirements.

[0003] Specifically, a cubic foundation pit is first excavated at a preset location, and a layer of waterproof composite geotextile is first laid in the cubic foundation pit. Then, a number of standard-sized PP modules are stacked and assembled on the composite geomembrane to form a cubic pool body, and side panels are fixed and installed on the side walls of the PP modules that serve as the side walls of the cubic pool body. Then, a lifting well is installed at the upper end of the pool body. After that, the entire pool body is wrapped with an anti-seepage composite geotextile and tied to the pool body with cable ties, and polystyrene boards are laid on the outside of the composite geotextile as a waterproof layer and enclosure structure. Finally, the underground water storage tank is formed after backfilling with earth. According to the "Construction and Acceptance Specifications for Water Supply and Drainage Structures", a full water test must be carried out after the construction of the water tank is completed, and no water leakage is allowed.

[0004] However, the pool wall, which is assembled from PP (polyethylene) modules and is made of a flexible structure such as composite geotextile, can easily deform and become unstable due to the lateral water pressure after the pool is filled with water, leading to unstable water level in the pool and inaccurate results of the full water test. Summary of the Invention

[0005] The present invention provides a road surface rainwater collection system to solve the above problems.

[0006] The present invention provides a road rainwater collection system employing the following technical solution: A road rainwater collection system comprises a polypropylene (PP) module, side panels, a drainage fabric, an intake fabric, a clamping ring, and a position limiting assembly. The PP modules are provided with a plurality of pool bodies stacked to form a cube; the pool bodies are located within a foundation pit.

[0007] There are four side panels, which are fixed on the four vertical side walls of the tank body respectively; the side panels are provided with limiting grooves with openings facing the foundation pit; the limiting grooves extend in the horizontal direction; the limiting grooves at the same height on the side panels on the four vertical side walls of the tank body form a rectangular ring groove;

[0008] The drainage cloth is laid in the foundation pit; the pool body is stacked on the drainage cloth; the drainage cloth is folded upwards and attached to the side panels.

[0009] The upper water-construction cloth covers the top of the pool body and is folded downward and attached to the lower water-construction cloth at the vertical side wall of the pool body.

[0010] The clamping ring is a rectangular ring. It is positioned within the retaining groove and squeezes and secures the lower and upper waterwork fabrics within the retaining groove. The clamping ring's tight seal on the lower and upper waterwork fabrics enhances the side panels' ability to resist lateral water pressure during a full-water test, preventing lateral movement and deformation that could lead to inaccurate test results. The clamping ring includes four right-angled portions and multiple straight portions, the number and length of which vary depending on the size of the tank. The right-angled and straight portions alternate and connect end-to-end to form a rectangular clamping ring. Nuts and bolts secure adjacent right-angled and straight portions. A first connecting hole is defined at each end of the right-angled portion, one of which is hexagonal. A second connecting hole is defined at each end of the straight portion, one of which is hexagonal and serves to accommodate a nut and restrict its rotation.

[0011] The limiting assembly is used to limit the tight ring in the limiting groove, and to make the lower water fabric squeezed into the limiting groove tightly abut against the upper water fabric to prevent water from flowing out of the pool or muddy water from flowing in.

[0012] Furthermore, the side panel includes a plurality of split panels; the plurality of split panels are distributed in an array to form a rectangular side panel; the split panels are provided with grooves extending in a horizontal direction; the grooves on the split panels at the same height are formed into limiting grooves.

[0013] Furthermore, the limiting assembly includes a slide groove; the slide groove is provided on the lower groove wall of the groove; the slide groove and the groove are connected; a limiting plate is installed in the slide groove so as to slide up and down; a wedge-shaped block with a small end facing upward is fixed to the upper end of the limiting plate; the side wall of the wedge block close to the pool body is set as a limiting wall; the limiting wall is set vertically; the side wall of the wedge block away from the pool body is set as a matching wall; the matching wall is set obliquely;

[0014] An elastic structure is connected between the limiting plate and the sliding groove; the elastic structure is used to make the upper end of the wedge block abut against the upper groove wall of the groove.

[0015] Furthermore, the elastic structure includes an elastic sheet; the elastic sheet is arranged to be tilted up and down, with the upper end fixedly connected to the limit plate and the lower end fixedly connected to the groove wall of the slide groove.

[0016] Furthermore, auxiliary columns are provided at the ends of two adjacent side panels that are close to each other; the auxiliary columns are vertically arranged rectangular columns; the lower ends of the auxiliary columns are fixed to the foundation pit; the four auxiliary columns and the four side panels form a rectangular tube; auxiliary grooves are provided on the auxiliary columns; the auxiliary grooves are connected to the limit grooves; the auxiliary grooves and the tightening rings cooperate to tighten and seal the lower and upper water fabrics at the right angles.

[0017] Furthermore, a rubber membrane is attached between the lower and upper water fabrics; the rubber membrane is located in the limiting groove. The clamping ring pushes against the mating wall of the wedge block, forcing the wedge block to drive the limiting plate downward, overcoming the elastic force of the elastic sheet and retracting it into the chute, pressing the lower and upper water fabrics into the limiting groove. When the wedge block is passed, the limiting plate drives the wedge block upward, and the upper end of the wedge block cooperates with the upper wall of the limiting groove to compress and seal the lower and upper water fabrics. The rubber membrane increases friction between the lower and upper water fabrics, preventing relative sliding and gaps when the lower or upper water fabrics are subsequently pulled.

[0018] Furthermore, the vertical cross-section of the straight portion of the tight hoop is circular.

[0019] Furthermore, a dovetail block is fixed on the side wall of the split plate close to the pool body; a dovetail groove is provided on the PP module; and the dovetail block is inserted into the dovetail groove.

[0020] The beneficial effects of the present invention are as follows: the tightening ring squeezes and tightens the lower water cloth and the upper water cloth at the limit groove into the limit groove; the tightening ring tightens and seals the lower water cloth and the upper water cloth, so that when conducting a full water test, the ability of the side plate to resist lateral water pressure is improved, the side plate is avoided from lateral movement, and deformation of the side plate is prevented from causing inaccurate test results.

[0021] Furthermore, the limiting assembly limits the tight ring in the limiting groove, and makes the lower water fabric squeezed into the limiting groove tightly abut against the upper water fabric to prevent water from flowing out of the pool body or muddy water from flowing in.

DETAILED DESCRIPTION

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] An embodiment of a road rainwater collection system of the present invention is as follows Figures 1 to 12As shown, it includes PP modules 100, side panels, lower water fabric 400, upper water fabric 500, tightening ring 600, and limit assembly. PP modules 100 are provided with multiple pool bodies stacked into a cube; the pool body is set in the foundation pit.

[0038] Four side panels are provided, fixed to the four vertical side walls of the tank body. The side panels are provided with retaining grooves 220 opening toward the foundation pit. The retaining grooves 220 extend horizontally. The retaining grooves 220 at the same height on the side panels on the four vertical side walls of the tank body form a rectangular annular groove. Auxiliary columns 300 are provided at the adjacent ends of two adjacent side panels. The auxiliary columns 300 are vertically arranged rectangular columns. The lower ends of the auxiliary columns 300 are fixed to the foundation pit. The four auxiliary columns 300 and the four side panels form a rectangular tube. The auxiliary columns 300 are provided with auxiliary grooves, which communicate with the retaining grooves 220. The auxiliary grooves and the clamping ring 600 cooperate to tighten and seal the lower and upper waterwork fabrics 400 and 500 at right angles. The side panels include multiple sub-panels 210, which are arranged in an array to form a rectangular side panel. The sub-panels 210 are provided with grooves extending horizontally. The grooves on the sub-panels 210 at the same height form the retaining grooves 220. A dovetail block 211 is fixed on the side wall of the partition plate 210 close to the tank body; a dovetail groove 110 is provided on the PP module 100; and the dovetail block 211 is inserted into the dovetail groove 110.

[0039] The drainage fabric 400 is laid in the foundation pit; the pool body is stacked on the drainage fabric 400; the drainage fabric 400 is folded upward and attached to the side panels. The upper drainage fabric 500 covers the top of the pool body and is folded downward and attached to the drainage fabric 400 on the vertical side walls of the pool body.

[0040] The clamping ring 600 is a rectangular ring. It is positioned within the retaining groove 220 and squeezes and secures the lower and upper waterwork fabrics 400 and 500 at the retaining groove 220. The clamping ring 600 seals the lower and upper waterwork fabrics 400 and 500, thereby enhancing the side panels' ability to resist lateral water pressure during a full-water test, preventing lateral movement and deformation that could lead to inaccurate test results. The clamping ring 600 includes four right-angled portions 610 and a plurality of straight portions 620. The number and length of these straight portions 620 vary depending on the size of the tank. The right-angled portions 610 and straight portions 620 alternate and connect end-to-end to form a rectangular clamping ring 600. Adjacent right-angled portions 610 and straight portions 620 are secured together by nuts and bolts. The straight portion 620 of the clamping ring 600 has a circular vertical cross-section. The right-angled portion 610 has first connecting holes 611 at both ends, one of which is hexagonal. The straight portion 620 has second connecting holes 621 at both ends, one of which is hexagonal and used to accommodate a nut and restrict its rotation.

[0041] The limiting assembly is used to restrict the clamping ring 600 within the limiting groove 220 and to ensure that the lower water-retaining fabric 400 squeezed into the limiting groove 220 is in close contact with the upper water-retaining fabric 500, thereby preventing water from flowing out of the tank body or muddy water from flowing in. The limiting assembly includes a chute 710; the chute 710 is provided on the lower wall of the groove; the chute 710 is connected to the groove; a limiting plate 720 is installed in the chute 710 for sliding up and down; a wedge block 730 with its small end facing upward is fixed to the upper end of the limiting plate 720; the side wall of the wedge block 730 near the tank body is provided as a limiting wall 731; the limiting wall 731 is arranged vertically; the side wall of the wedge block 730 away from the tank body is provided as a matching wall 732; the matching wall 732 is arranged obliquely; an elastic structure is connected between the limiting plate 720 and the chute 710; the elastic structure is used to make the upper end of the wedge block 730 abut against the upper wall of the groove. The elastic structure includes an elastic piece 740 ; the elastic piece 740 is tilted up and down, with the upper end fixedly connected to the limit plate 720 and the lower end fixedly connected to the groove wall of the sliding groove 710 .

[0042] In this embodiment, a rubber membrane is attached between the lower and upper waterwork fabrics 400, 500; the rubber membrane is located in the retaining groove 220. The clamping ring 600 pushes against the mating wall 732 of the wedge block 730, forcing the wedge block 730 to move the retaining plate 720 downward, overcoming the elastic force of the elastic sheet 740 and retracting it into the chute 710. This in turn presses the lower and upper waterwork fabrics 400, 500, into the retaining groove 220. When the wedge block 730 is passed, the retaining plate 720 drives the wedge block 730 upward. The upper end of the wedge block 730 cooperates with the upper wall of the retaining groove 220 to compress and seal the lower and upper waterwork fabrics 400, 500. The rubber membrane increases friction between the lower and upper waterwork fabrics 400, 500, preventing relative sliding and gap formation when the lower and upper waterwork fabrics 400, 500, are subsequently pulled.

[0043] In combination with the above embodiments, the operating principle and working process of the present invention are as follows: First, a layer of drainage fabric 400 is laid in the foundation pit. Then, the PP modules 100 are stacked on the drainage fabric 400 to form a cubic pool body, and four side panels are fixed on the four vertical side walls of the pool body. The auxiliary columns 300 are placed at the ends of two adjacent side panels close to each other, so that the four auxiliary columns 300 and the four side panels form a rectangular tube, and the lower ends of the auxiliary columns 300 are inserted into the bottom wall of the foundation pit for fixation. The operator can use a temporary long pole with a cross-sectional width greater than or equal to the depth of the limiting groove 220 to push the drainage fabric 400 from bottom to top, and then fold the drainage fabric 400 upward and attach it to the side panels.

[0044] When the temporary long rod moves to the limiting groove 220, the temporary long rod pushes against the mating wall 732 of the wedge block 730, driving the wedge block 730 to drive the limiting plate 720 to overcome the elastic force of the elastic sheet 740 and move downward into the slide groove 710, thereby pressing the water-discharging fabric 400 into the limiting groove 220. Then, the temporary long rod is pulled out of the limiting groove 220, and the elastic sheet 740 drives the limiting plate 720 to move upward. The upper end of the wedge block 730 cooperates with the upper groove wall of the limiting groove 220 to press the water-discharging fabric 400 against the upper groove wall of the limiting groove 220. Then, the temporary long rod is pulled out of the limiting groove 220; then, the temporary long rod is used to push the upper water-discharging fabric 500 from top to bottom, causing the upper water-discharging fabric 500 to fold downward and adhere to the lower water-discharging fabric 400 at the vertical side wall of the pool body. When the temporary long rod moves to the limiting groove 220 again, the temporary long rod pushes the matching wall 732 of the wedge block 730, driving the wedge block 730 to drive the limiting plate 720 to overcome the elastic force of the elastic sheet 740 and move downward into the slide groove 710, and press the water-feeding fabric 500 into the limiting groove 220. Then, after pulling the temporary long rod out from the limiting groove 220 again, the straight portion 620 and the right-angle portion 610 of the tightening ring 600 are inserted into the limiting groove 220.

[0045] When the straight portion 620 of the clamping ring 600 passes over the wedge block 730, the limiting plate 720 drives the wedge block 730 upward. The upper end of the wedge block 730 cooperates with the upper wall of the limiting groove 220 to press and seal the lower waterwork fabric 400 and the upper waterwork fabric 500 against the upper wall of the limiting groove 220. The straight portion 620 of the clamping ring 600 abuts the limiting wall 731 of the wedge block 730. Before pressing the straight portion 620 of the clamping ring 600 into the limiting groove 220, a nut or bolt must be placed in the corresponding hexagonal opening of the second connecting hole 621. Similarly, the right-angled portion 610 of the clamping ring 600 is inserted into the limiting groove 220, and the straight portion 620 and the right-angled portion 610 of the clamping ring 600 are fastened to the ring-shaped clamping ring 600 using bolts and nuts. The tight seal of the lower and upper water fabrics 400 and 500 by the clamping ring 600 enhances the side panels' ability to resist lateral water pressure during the full-water test, preventing lateral movement and deformation that could lead to inaccurate test results. After the hoistway is installed, protective panels are laid outside the upper water fabric 500, and the foundation pit is backfilled.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
