Description

Technical Field

[0001] This utility model relates to the technical field of permeable concrete precast components, specifically to a permeable concrete precast component. Background Technology

[0002] Permeable concrete, also known as porous concrete, no-fines concrete, or permeable pavement, is a type of porous lightweight concrete made from aggregates, cement, reinforcing agents, and water. It contains no fine aggregates; instead, the coarse aggregates are bonded together by a thin layer of cement paste, forming a honeycomb structure with evenly distributed pores. It possesses advantages such as air permeability, water permeability, and light weight. Therefore, permeable concrete is widely used in modern urban construction, landscaping, and sponge city projects.

[0003] Existing permeable concrete precast components, due to their excellent permeability, are commonly used in sidewalks, plazas, and parking lots, effectively ensuring drainage while maintaining structural support. However, in cold regions, the moisture inside these components expands upon freezing, causing the components to swell and potentially crack or even break, ultimately affecting their performance. Therefore, we propose a permeable concrete precast component to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a permeable concrete precast component, including a bottom support plate 1, an upper water guiding membrane 2 provided on the upper surface of the bottom support plate 1, a lower water guiding membrane 3 provided on the lower surface of the bottom support plate 1, a rib fixing plate 4 provided on the upper surface of the upper water guiding membrane 2, a plurality of water guiding pipes 5 evenly spaced on the lower surface of the upper water guiding membrane 2, a top support plate 6 provided on the upper surface of the rib fixing plate 4, and a plurality of reinforcing ribs 7 evenly spaced on the lower surface of the top support plate 6;

[0023] Multiple water guide channels 101 are vertically and evenly spaced on the bottom support plate 1, and two inclined surfaces 102 are symmetrically arranged on the top two sides of the water guide channels 101.

[0024] The upper water-guiding membrane 2 is fixedly connected to the upper surface of the bottom support plate 1, and the lower water-guiding membrane 3 is fixedly connected to the lower surface and side of the bottom support plate 1. In this example, by setting the upper water-guiding membrane 3, water can be prevented from flowing into the bottom support plate 1 from the top, thus avoiding freezing expansion and causing the bottom support plate 1 to crack.

[0025] Two inclined surfaces 501 are symmetrically arranged on both sides of the top of the water guide pipe 5. The outer side of the water guide pipe 5 is fixedly connected to the water guide channel 101, the top of the water guide pipe 5 is fixedly connected to the upper water guide membrane 2, and the bottom of the water guide pipe 5 is fixedly connected to the lower water guide membrane 3. The two inclined surfaces 501 are respectively fixedly connected to the two inclined surfaces 102 of the channel. In this example, by setting the water guide pipe 5, the water flow can be unblocked and blockages can be avoided.

[0026] Multiple top drainage grooves 601 are evenly spaced on the top support plate 6, and multiple top mounting grooves 602 are evenly spaced on the lower surface of the top support plate 6. The lower surface of the top support plate 6 is fixedly connected to the upper surface of the rib fixing plate 4. Two rib fixing grooves 603 are symmetrically arranged at both ends of the multiple top mounting grooves 602, and the top mounting grooves 602 and the multiple top drainage grooves 601 are spaced apart. In this example, by setting multiple top drainage grooves 601, it is convenient to drain water quickly and provide space for the expansion of the top support plate 6.

[0027] Multiple rib drainage grooves 401 are evenly spaced on the rib fixing plate 4. The lower surface of the rib fixing plate 4 is fixedly connected to the upper surface of the upper water guiding membrane 2. Multiple bottom mounting grooves 402 are spaced between the multiple rib drainage grooves 401. The rib drainage grooves 401 are aligned and connected with multiple top drainage grooves 601. Two rib fixing bottom grooves 403 are symmetrically arranged at both ends of the multiple bottom mounting grooves 402. In this example, by setting two rib fixing bottom grooves 403, it is convenient to fix the reinforcing ribs 7 to provide structural strength.

[0028] The upper and lower sides of multiple reinforcing ribs 7 are fixedly connected inside the top groove 603 and the bottom groove 403 of the rib fixing, respectively. In this example, by setting multiple reinforcing ribs 7, the structural strength can be improved.

[0029] Working principle: Water flows through multiple top drainage channels 601 on the top support plate 6 to the bottom rib fixing plate 4, and then through multiple rib drainage channels 401 to the bottom upper water guiding film 2. Through multiple water guiding pipes 5, it flows through the bottom support plate 1 into the ground. When the water freezes and expands, the top support plate 6 expands into the multiple top drainage channels 601 and the top mounting groove 602, and the rib fixing plate 4 expands into the multiple rib drainage channels 401 and the bottom mounting groove 402, thus eliminating the internal expansion stress.
