Description

Technical Field

[0001] This utility model belongs to the field of sponge city road paving technology, and in particular relates to a permeable garden road paving structure. Background Technology

[0002] A sponge city refers to a city that possesses excellent resilience in adapting to environmental changes and responding to natural disasters caused by rainwater. Permeable pavement is an important component of a sponge city. Like a sponge, it can quickly absorb surface water, allowing it to infiltrate into the ground, effectively replenishing groundwater and mitigating the urban heat island effect. Common permeable pavements typically consist of a surface layer made of permeable bricks, a base layer beneath the surface layer to support it, and rainwater infiltrates through the surface layer into the base layer for drainage. However, this type of structure suffers from backflow and limited infiltration capacity during heavy rainfall, failing to effectively eliminate rainwater and leading to road surface flooding. Utility Model Content

[0003] In view of this, in order to solve the technical problem that the existing permeable pavement structure has defects and cannot eliminate water accumulation in time when the rainfall is too heavy, this utility model proposes a permeable garden road pavement structure that adopts an integrated structure design of infiltration, storage and drainage to achieve rapid elimination of water accumulation.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A permeable garden road paving structure includes, from top to bottom, a permeable brick facing layer, a transition leveling layer, a first permeable geotextile layer, a water storage and drainage layer, a second permeable geotextile layer, a graded crushed stone load-bearing layer, and a foundation compaction layer; the water storage and drainage layer includes a multi-cell support frame and zeolite particles filled in each cell of the multi-cell support frame, the multi-cell support frame is provided with drainage channels, the drainage channels are connected to each cell and to an external drainage ditch.

[0006] Furthermore, the permeable brick cladding layer comprises multiple permeable bricks joined in a herringbone pattern.

[0007] Furthermore, the transition leveling layer is made of a mixture of coarse sand, activated carbon, and graded crushed stone.

[0008] Coarse sand can intercept large particles of impurities, activated carbon can adsorb organic matter, and graded crushed stone enhances structural stability.

[0009] Furthermore, both the first and second permeable geotextile layers are composed of geogrids and permeable geotextiles laid on the geogrids.

[0010] The first layer of water-permeable geotextile and the second layer of permeable geotextile protect the water storage and drainage layer without affecting the infiltration of rainwater, while the geogrid also provides a certain degree of support.

[0011] Furthermore, the foundation compaction layer is made of a mixture of soil and sand.

[0012] Furthermore, the multi-grid support frame includes two main drainage pipes located on both sides of the road along the length of the road, a water guide pipe perpendicular to the main drainage pipes and connected to the two main drainage pipes at both ends, and a support rib parallel to the main drainage pipes and intersecting the water guide pipes in a cross shape; both the main drainage pipes and the water guide pipes are provided with drainage channels; both ends of the main drainage pipes are connected to external drainage ditches; and multiple water inlets are opened on the side of the water guide pipes corresponding to the zeolite particles filled in.

[0013] When a large amount of rainwater infiltrates into the water storage and drainage layer, some of the rainwater continues to infiltrate downwards, some of the rainwater is absorbed in the zeolite, and the remaining rainwater that cannot be treated in time flows from each cell through the inlet hole into the water pipe, and then flows into the main drainage pipe, from which it is discharged into the external drainage ditch. Through the conventional infiltration mode, combined with short-term water storage and timely drainage, the drainage pressure on the road surface during heavy rain is effectively relieved.

[0014] Compared with existing technologies, the permeable garden road paving structure of this utility model has the following advantages:

[0015] (1) The permeable garden road paving structure described in this utility model combines the permeable structure set in layers with the drainage function of the water storage and drainage layer itself and the water storage performance of zeolite to achieve the integration of "infiltration + storage + drainage", which can quickly eliminate road surface water and reduce the situation of road surface water or back seepage during heavy rainfall.

[0016] (2) The coarse sand in the transition leveling layer described in this utility model can intercept large particles of impurities, activated carbon adsorbs organic matter, and graded crushed stone enhances structural stability; the first and second permeable geotextile layers play the role of protecting the water storage and drainage layer; the water storage and drainage layer plays the role of permeability, water storage and drainage; the graded crushed stone load-bearing layer is the main load-bearing layer.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 3 As shown, a permeable garden road paving structure includes, from top to bottom, a permeable brick facing layer 1, a transition leveling layer 2, a permeable geotextile layer 1 3, a water storage and drainage layer 4, a permeable geotextile layer 2 5, a graded crushed stone load-bearing layer 6, and a foundation compaction layer 7.

[0028] The permeable brick facing layer 1 comprises multiple permeable bricks joined in a herringbone pattern;

[0029] The transition leveling layer 2 is made of a mixture of coarse sand, activated carbon, and graded crushed stone.

[0030] Both the first permeable geotextile layer 3 and the second permeable geotextile layer 5 are composed of geogrids and permeable geotextiles laid on the geogrids.

[0031] The water storage and drainage layer 4 includes a multi-compartment support frame and zeolite particles 8 filled in each compartment of the multi-compartment support frame; the multi-compartment support frame includes two main drainage pipes 9 located on both sides of the road along the length of the road, a water guide pipe 10 perpendicular to the main drainage pipes 9 and connected to the two main drainage pipes 9 at both ends, and a support rib 11 parallel to the main drainage pipes 9 and intersecting the water guide pipes 10 in a cross shape; both the main drainage pipes 9 and the water guide pipes 10 are provided with drainage channels 12; both ends of the main drainage pipes 9 are connected to the external drainage ditch; the water guide pipes 10 have multiple water inlet holes 13 on the side corresponding to the filled zeolite particles 8.

[0032] The basic compaction layer 7 is made of a mixture of soil and sand.

[0033] The working principle of the permeable garden road paving structure described in this embodiment is as follows:

[0034] Rainwater infiltrates sequentially through the permeable brick surface layer 1, transition leveling layer 2, permeable geotextile layer 1 3, water storage and drainage layer 4, permeable geotextile layer 2 5, graded crushed stone load-bearing layer 6, and foundation compaction layer 7. When the rainfall is heavy, after the rainwater infiltrates into the water storage and drainage layer 4, some of the rainwater continues to infiltrate downwards, while some of the rainwater is adsorbed into the zeolite particles 8 (zeolite can improve the short-term water storage capacity of the road pavement structure). The remaining rainwater that cannot be treated in time flows from each cell through the inlet hole 13 into the water pipe 10, and then flows into the main drainage pipe 9, from which it is discharged into the external drainage ditch.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
