Description

Technical Field

[0001] This invention belongs to the field of anti-slip and permeable paving structures for buildings, and specifically relates to an anti-slip and permeable paving structure and construction method for building boundaries. Background Technology

[0002] Against the backdrop of rapid urbanization and the construction of sponge cities, traditional hard paving is prone to water accumulation and slipping, and rainwater infiltration is hindered. Anti-slip permeable paving structures at building boundaries have emerged and are widely used in building boundary roads, municipal engineering, residential communities, garden landscapes, school squares and the surrounding areas of commercial buildings. This structure consists of a porous permeable surface layer combined with a stable base layer and a filter layer, which has both high permeability and high anti-slip performance. It can quickly drain rainwater, reduce road water accumulation, improve pedestrian safety, optimize the microenvironment at building boundaries, and take into account both ecological benefits and safety of use. Existing pavement structures of the same type have poor water permeability and air permeability, making it difficult for water and internal moisture to drain quickly, which easily leads to long-term dampness of the road surface. They also have limited water passage space and insufficient buffering capacity, weak overall support, compressive strength and deformation resistance, and the surface layer is easily deformed and damaged under pressure. At the same time, they have insufficient friction resistance and poor anti-slip effect in waterlogged environments, which not only affects traffic safety but also shortens the service life of the structure. Therefore, an anti-slip permeable pavement structure for building boundaries is proposed to solve the above problems. Summary of the Invention

[0003] The present invention aims to solve the problems of poor water permeability and air permeability, weak overall support, compressive strength and deformation resistance, and easy surface deformation and damage in the existing anti-slip permeable pavement structure at the building boundary.

[0004] In view of the above-mentioned defects or improvement needs of the prior art, the present invention relates to an anti-slip and permeable paving structure for building boundaries, including a foundation, a main roadbed, permeable gravel, a soil foundation and a drainage ditch; The main roadbed is fixedly installed on the top of the foundation, and the main roadbed consists of an anti-slip and permeable surface layer, a permeable support layer and a load-bearing base layer from top to bottom. The anti-slip and water-permeable surface layer is made of water-permeable material, and its upper surface has raised anti-slip textures. The permeable support layer has an array of diamond-shaped grooves inside. The load-bearing base layer has several parallel arched grooves inside, and X-shaped reinforcing bars are fixedly installed on the inner wall of the arched grooves. Multiple water seepage holes are opened on the top wall of the arched grooves. Vertical drainage channels are provided on both sides of the main roadbed, and the vertical drainage channels are connected to the drainage ditch. The soil foundation is set on the left and right sides of the foundation, the drainage ditch is laid on the top of the soil foundation, the permeable gravel is laid on the top of the drainage ditch, and the drainage ditch is provided with a longitudinal slope of %.

[0005] Furthermore, the permeable support layer is a porous ceramsite concrete permeable support layer, and the rhomboid grooves are evenly distributed in an array inside the porous ceramsite concrete permeable support layer.

[0006] Furthermore, the X-shaped reinforcing ribs are arranged in a linear array on the inner wall of the arched groove, and both ends of the X-shaped reinforcing ribs are fixedly connected to the inner sidewall of the arched groove.

[0007] Furthermore, the anti-slip and permeable surface layer is provided with transverse water guiding grooves.

[0008] Furthermore, the anti-slip and permeable surface layer and the permeable support layer are vertically connected by a number of breathable and drainage holes, and the bottom end of the breathable and drainage holes is connected to the diamond-shaped groove.

[0009] Furthermore, the seepage hole connects the rhomboid groove and the arched groove opening.

[0010] Furthermore, a light-gathering reflective strip is embedded inside the groove of the anti-slip texture.

[0011] Furthermore, ceramic wear-resistant particles are embedded inside the anti-slip texture, and temperature-sensitive self-healing adhesive powder is also added inside the anti-slip texture.

[0012] As another aspect of this invention, a drainage method for anti-slip and permeable pavement structures at building boundaries is also provided, comprising the following steps: 1) After rainwater falls on the surface of the main roadbed, some of it seeps into the asphalt mixture layer and enters the diamond-shaped grooves in the porous ceramsite concrete permeable support layer through the ventilation and drainage holes. 2) The water accumulated in the diamond-shaped groove flows into the arched groove through the seepage holes. The X-shaped reinforcing bars in the arched groove enhance the structure's compressive strength without affecting the water flow. 3) The accumulated water inside the main roadbed is diverted outward through the drainage channels on both sides. The outside of the drainage channels is attached to the drainage ditch, and the rainwater is discharged into the drainage ditch. 4) The foundation is closely integrated with the main roadbed to provide stable support, and the soil foundation combined with permeable gravel forms an auxiliary bearing and drainage system; 5) The anti-slip texture on the surface of the main roadbed increases contact friction and reduces the risk of slippage when there is water accumulation on the road surface.

[0013] Furthermore, the method for determining the dimensions of the X-shaped reinforcing bar is as follows: The X-shaped reinforcing bars are arranged along a fixed longitudinal length, and their single-limb length is... The pavement structure has a fixed longitudinal length; the total external vertical force Distribute evenly to The longitudinally arranged X-shaped reinforcing bars are controlled by the bending moment of inertia of the cross section as the strength criterion, the allowable strength of the material as the constraint condition, and the array spacing as the constraint condition. Using strength constraints and material optimization inequality models as independent variables, The specific model building method is as follows: (1) Determine the stress of a single reinforcement: ; (2) Moment of inertia constraint of bending section: ; (3) Calculation of cross-sectional area: ; (4) Array spacing independent variable constraint: ; The model determines the minimum cross-sectional area that meets the strength requirements using the above formula. With maximum array spacing This achieves an optimized design that balances structural safety with minimal material usage.

[0014] —Vertical loads borne by the pavement structure; —The uniform distribution of stress by a single X-shaped reinforcing bar; —The total number of longitudinally arranged X-shaped reinforcing bars, dimensionless; —The length of a single leg of the X-shaped reinforcing bar is the longitudinal fixed length of the pavement structure; —Moment of inertia of a single limb section of the X-type reinforcing bar; —The distance from the outermost edge of the reinforced section to the neutral axis; —Allowable bending stress of X-type reinforcing bar material; —Pedestrian dynamic load correction factor, value ; —Structural safety factor, value ; —Cross-sectional area of ​​a single leg of the X-type reinforcing bar; —Height of X-type reinforcing bar section, in units; — Spacing of the X-shaped reinforcing bar array; —Total longitudinal length of the pavement structure.

[0015] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: (1) The anti-slip and permeable pavement structure of the building boundary of the present invention, through a multi-level permeable structure and a spatial reinforcement structure, significantly improves the road surface's compressive and deformation resistance while ensuring high permeability. (2) The anti-slip and permeable pavement structure of the building boundary of the present invention can minimize the use of reinforcing materials, improve the compressive and deformation resistance of the arched groove, and extend the overall service life of the pavement structure by controlling the bending moment of the cross section of the X-shaped reinforcing bars and optimizing the array spacing independent variable model.

[0016] (3) The anti-slip and permeable paving structure of the building boundary of the present invention expands the water flow cross section and buffers the water flow through the array of diamond grooves. The arched channel and the reinforced rib form a load-bearing skeleton to avoid structural damage caused by internal voids. The side drainage and filter layer are combined to achieve rapid drainage, anti-clogging, anti-settlement, anti-root penetration and anti-slip in the building boundary scene. It is especially suitable for boundary areas such as building perimeter, community roads and landscape walkways, taking into account ecological drainage and structural durability.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Reference Figures 1-3The embodiment provided by the present invention: a non-slip permeable paving structure for building boundaries, including a main roadbed 2, a foundation 1 fixedly connected to the bottom of the main roadbed 2, soil foundations 5 fixedly connected to both sides of the foundation 1, a drainage ditch 14 fixedly laid on the top of the soil foundation 5, a permeable gravel layer 6 laid above the drainage ditch 14, and multiple drainage channels 13 linearly and evenly distributed on the outer walls of both sides of the main roadbed 2, the drainage channels 13 connecting the side walls of the main roadbed 2 and the drainage ditch 14, and the opening height of the drainage channels 13 being adapted to the laying height of the permeable gravel layer 6.

[0022] After rainwater falls on the surface of the main roadbed 2, it flows into the drainage ditch 14 through multiple drainage channels 13 on both sides of the main roadbed 2, achieving rapid drainage and preventing surface water accumulation. The foundation 1 is firmly integrated with the main roadbed 2, providing stable support for the overall structure. The soil foundation 5 on both sides, together with the permeable crushed stone layer 6, forms an auxiliary drainage and load-bearing system. The setting height of the drainage channel 13 is matched with the paving height of the permeable crushed stone layer 6 to ensure smooth water flow and reduce water accumulation. At the same time, the overall structure relies on the cooperation between the layers to improve the stability of the road surface. When pedestrians or vehicles pass, the main roadbed 2 and the foundation 1 share the load. The drainage ditch 14 and the drainage channel 13 work together to continuously drain water, keep the road surface dry, and improve the anti-slip effect and structural stability during passage.

[0023] Reference Figures 1-3 The top wall of the main roadbed 2 has multiple evenly distributed ventilation and drainage holes 12. The surface layer of the main roadbed 2 is an asphalt mixture layer 7. Inside the main roadbed 2, below the asphalt mixture layer 7, a porous ceramsite concrete permeable support layer 4 is fixedly laid. Inside the porous ceramsite concrete permeable support layer 4, multiple evenly distributed diamond-shaped grooves 11 are opened. The ventilation and drainage holes 12 vertically penetrate the asphalt mixture layer 7 and the porous ceramsite concrete permeable support layer 4, and the bottom end of the ventilation and drainage holes 12 is connected to the diamond-shaped grooves 11.

[0024] Rainwater and road surface moisture infiltrate through the asphalt mixture layer 7 and are then channeled downwards through the vertically penetrating permeable drainage holes 12. The water flows through the asphalt mixture layer 7 and the porous ceramsite concrete permeable support layer 4 before entering the internal diamond-shaped grooves 11. These grooves 11 are distributed in an array within the porous ceramsite concrete permeable support layer 4, expanding the water flow space and mitigating water impact. The porous ceramsite concrete permeable support layer 4, while absorbing water, provides reliable support for the upper structure, preventing surface deformation under pressure. The permeable drainage holes 12 and the diamond-shaped grooves 11 are interconnected, forming a continuous drainage channel that allows accumulated water to quickly collect downwards and be channeled outwards, reducing its retention on the surface of the asphalt mixture layer 7. The distribution of the porous ceramsite concrete diamond-shaped grooves 11 enhances overall permeability and air permeability, keeping the road surface dry. The asphalt mixture layer 7 and the porous ceramsite concrete permeable support layer 4 work together to form a stable load-bearing and drainage system, improving drainage capacity while enhancing the overall structural integrity of the road surface, ensuring structural stability and traffic safety during use.

[0025] Reference Figures 1-2 Inside the main roadbed 2, below the porous ceramsite concrete permeable support layer 4, there are multiple parallel and equidistant arched slots 8. The top wall of the arched slots 8 has multiple seepage holes 9 that are connected to the porous ceramsite concrete permeable support layer 4. The inner wall of the arched slots 8 is fixedly connected with multiple X-shaped reinforcing bars 10 that are arranged in a straight array. Both ends of the X-shaped reinforcing bars 10 are fixedly connected to the inner side wall of the arched slots 8.

[0026] After flowing through the porous ceramsite concrete permeable support layer 4, water enters the lower arched groove 8 through the seepage holes 9. The arched grooves 8 are arranged in parallel and equidistant to form a continuous water passage, which accelerates the drainage of accumulated water. X-shaped reinforcing bars 10 are arranged in a straight array along the inner wall of the arched groove 8, with both ends firmly connected to the groove wall, which enhances the overall structure's resistance to pressure and deformation. The arc-shaped structure of the arched groove 8 can distribute the upper load and reduce the risk of pressure damage to the main roadbed 2. The seepage holes 9 and the arched groove 8 work together to achieve layered drainage, preventing water from accumulating inside. The X-shaped reinforcing bars 10 and the arched groove 8 work together to improve the structural strength, while not hindering the flow of water, so that drainage and structural support are achieved simultaneously, maintaining the long-term stable operation of the pavement structure.

[0027] Reference Figure 3 The top surface of the main roadbed 2 is provided with multiple uniformly distributed anti-slip patterns 3, which protrude from the upper surface of the asphalt mixture layer 7.

[0028] The anti-slip texture 3 on the top of the main roadbed 2 is raised on the surface of the asphalt mixture layer 7, which increases the frictional resistance between the road surface and the contact object, reduces slippage when walking or driving, and the raised texture is evenly distributed, which can maintain a good friction effect even when there is water on the road surface, thus improving the overall safety of the pavement structure.

[0029] Reference Figure 3 The inner end of the drainage trough 13 is connected to the interior of the main roadbed 2, and the outer end is connected to the drainage ditch 14.

[0030] Water accumulated inside the main roadbed 2 can be discharged outward through the inner end of the drainage trough 13. The outer end of the drainage trough 13 is close to the drainage ditch 14, and rainwater is quickly drained to prevent water from accumulating inside the main roadbed 2, ensuring smooth drainage while maintaining the stability of the connection between structures.

[0031] Working principle: After rainwater falls on the surface of the main roadbed 2, some of it seeps into the asphalt mixture layer 7 and enters the diamond-shaped groove 11 in the porous ceramsite concrete permeable support layer 4 through the ventilation and drainage holes 12. Then, it flows into the arched groove 8 through the seepage holes 9. The X-shaped reinforcing bars 10 in the arched groove 8 enhance the compressive strength of the structure without affecting the flow of water. The water collected inside the main roadbed 2 is diverted outward through the drainage channels 13 on both sides. The drainage channels 13 are attached to the drainage ditch 14 on the outside, and the rainwater is discharged into the drainage ditch. The foundation 1 is closely integrated with the main roadbed 2 to provide stable support. The soil foundation 5, together with the permeable crushed stone layer 6, forms an auxiliary bearing and drainage system. The anti-slip texture 3 on the upper surface of the main roadbed 2 increases the contact friction, which can reduce the risk of slippage even if there is water on the road surface. The various structural layers and drainage channels work together to achieve rapid drainage and ventilation, while dispersing the traffic load, keeping the road surface dry and stable, and improving the anti-slip performance and service durability of the overall pavement structure.

[0032] The anti-slip and permeable paving structure of the building boundary includes a main roadbed, the bottom of which is fixedly connected to a foundation, and soil foundations are fixedly connected to both sides of the foundation. A drainage ditch is fixedly laid on top of the soil foundation. Multiple drainage channels are opened on the outer walls of both sides of the main roadbed in a linear and uniform distribution. The drainage channels are connected between the side walls of the main roadbed and the drainage ditch, and the opening height of the drainage channels is adapted to the paving height of the permeable crushed stone layer.

[0033] In some preferred embodiments: the top wall of the main roadbed has a plurality of evenly distributed ventilating and draining holes; the surface layer of the main roadbed is an asphalt mixture layer; a porous ceramsite concrete permeable support layer is fixedly laid inside the main roadbed below the asphalt mixture layer; the porous ceramsite concrete permeable support layer has a plurality of evenly distributed rhomboid grooves inside; the ventilating and draining holes vertically penetrate the asphalt mixture layer and the porous ceramsite concrete permeable support layer, and the bottom end of the ventilating and draining holes is connected to the rhomboid grooves.

[0034] In some preferred embodiments: the main roadbed has multiple parallel and equidistant arched slots located below the porous ceramsite concrete permeable support layer. The top wall of the arched slots has multiple seepage holes that communicate with the porous ceramsite concrete permeable support layer. The inner wall of the arched slots is fixedly connected to multiple X-shaped reinforcing bars arranged in a linear array. Both ends of the X-shaped reinforcing bars are fixedly connected to the inner sidewall of the arched slots.

[0035] In some preferred embodiments: the top surface of the main roadbed is provided with a plurality of uniformly distributed anti-slip patterns, which are raised on the upper surface of the asphalt mixture layer.

[0036] In some preferred embodiments: the inner end of the drainage ditch is connected to the interior of the main roadbed, and the outer end is attached to the inner wall of the permeable gravel layer.

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