Description

Technical Field

[0001] This utility model belongs to the field of road drainage technology, and in particular relates to an embedded grate module and an integrated flow-guiding side stone structure for sponge cities. Background Technology

[0002] In traditional urban construction, road curbs are typically designed as closed systems, allowing rainwater to enter the underground drainage network only through storm drain grates. This design presents the following problems: 1. Insufficient control of rainwater runoff: During heavy rainfall, rainwater cannot infiltrate or remain quickly, leading to water accumulation on roads or even urban flooding.

[0003] 2. Waste of rainwater resources: Rainwater is directly discharged into the pipe network, failing to effectively replenish groundwater or be reused.

[0004] 3. Pollutant diffusion: Initial rainwater carries road pollutants (such as oil and heavy metals) directly into water bodies, exacerbating non-point source pollution.

[0005] To meet the needs of sponge city construction, some improved solutions have emerged in existing technologies, such as: 1. Curb opening drainage: Openings are made on the curb stones to allow rainwater to flow into green belts or bioretention facilities (such as rain gardens).

[0006] 2. Permeable curbstone: It adopts porous concrete or open structure to enhance the rainwater infiltration capacity.

[0007] However, existing sidestone opening technology still has the following drawbacks: 1. Insufficient structural strength: The opening design may affect the compressive and impact resistance of the curbstone, making it susceptible to damage from vehicle crushing.

[0008] 2. Siltation and blockage: The opening is easily blocked by fallen leaves and silt, which reduces drainage efficiency and increases maintenance costs.

[0009] 3. Limited drainage effect: Some designs only have simple openings and lack a scientific drainage structure, making them unable to adapt to different rainfall intensities. Generally, the cross slope and longitudinal slope of roads form a certain angle, resulting in poor drainage effect.

[0010] 4. Poor landscape harmony: The opening design is crude, affecting the aesthetics of urban roads. With the promotion of sponge city construction, curbstone opening technology is developing towards high-performance materials, modularization, and intelligence. This utility model, through structural innovation, overcomes the shortcomings of existing technologies and provides a more efficient and reliable solution for urban stormwater management. Summary of the Invention

[0011] This utility model provides an embedded grate module and an integrated flow-guiding sidewall structure for sponge cities, which solves at least one of the technical problems mentioned in the background art.

[0012] One technical solution of this utility model is as follows: An embedded grate module for sponge cities includes: a flat grate ring and a vertical grate ring. The vertical grate ring is vertically arranged, and the flat grate ring is horizontally arranged. The flat grate ring is located on one side of the vertical grate ring. A horizontal grate is provided on the top of the flat grate ring. A vertical grate is provided on the side of the vertical grate ring near the flat grate ring. A horizontal filter screen is provided at the bottom of the flat grate ring. A vertical filter screen is provided on the side of the vertical grate ring away from the flat grate ring. The flat grate ring and the vertical grate ring are connected.

[0013] Furthermore, the horizontal and vertical grates are uniformly provided with guide holes, and the partition strips between adjacent guide holes are wavy.

[0014] Furthermore, the flat grate ring is connected to the horizontal grate via a socket, snap fastener, hinge, or bolt, and the vertical grate ring is connected to the vertical grate ring via a socket, snap fastener, hinge, or bolt.

[0015] Another technical solution of this utility model is as follows: an integrated flow-guiding sidestone structure for sponge cities, comprising a flat stone body, a sidestone body, and any of the above-mentioned embedded grate modules for sponge cities, wherein the flat grate ring is embedded in the flat stone body, the vertical grate ring is embedded in the sidestone body, the sidestone body has a sidestone opening, and the vertical filter screen is disposed at the sidestone opening.

[0016] Furthermore, the flat stone body and the side stone body are installed on the concrete pad layer.

[0017] Furthermore, a sedimentation zone is provided between the horizontal filter screen and the concrete subbase.

[0018] Furthermore, the flat stone body and the side stone body are fixed to the concrete pad layer by cement mortar.

[0019] Furthermore, the top of the vertical grate ring is provided with an imitation stone surface.

[0020] The beneficial effects of this utility model are: 1. High strength and durability: Optimized opening layout and materials ensure the structural stability of the curbstone under vehicle loads.

[0021] 2. High efficiency in preventing blockage: The flat stone diversion channel provides initial sludge settling, and the double-layer filtration of the grate and filter screen (coarse filtration + fine filtration) reduces the pipe network blockage rate by more than 40%.

[0022] 3. Improved drainage efficiency: The design of the diversion channel and diversion hole accelerates rainwater discharge and improves the rainwater runoff effect.

[0023] 4. Combining practicality and aesthetics: It adopts a modular design and can be seamlessly integrated with sponge facilities such as road paving stones, green belts, and permeable paving.

[0024] 5. Modular design: The modular design allows for easy transportation, installation, and partial replacement.

[0025] This invention overcomes the problems of low strength and easy clogging of traditional side stone openings, improves drainage efficiency by more than 30%, and has a high degree of landscape integration, making it suitable for sponge city construction in urban roads and garden areas.
