Description

Technical Field

[0001] This utility model relates to the field of paving block technology, specifically a permeable paving block structure. Background Technology

[0002] With the acceleration of urbanization and the growth in demand for infrastructure construction, the number of various slope projects (such as highway slopes, riverbank protection, and mountain parks) has increased dramatically. Traditional slope treatment methods mainly use concrete hardening or simple grass planting for protection, which have the following prominent problems:

[0003] Hydrological imbalance: Hardened slopes completely block rainwater infiltration, leading to concentrated surface runoff and exacerbating downstream drainage pressure. Lack of effective rainwater retention and purification systems results in runoff carrying large amounts of pollutants being directly discharged into water bodies. Poor ecological performance: Single concrete structures damage the natural landscape and cannot support vegetation growth. Traditional grass-planted slope protection suffers from severe soil erosion, low vegetation survival rates, and high long-term maintenance costs. Structural safety hazards: During heavy rains, concentrated runoff easily forms on slopes, causing severe erosion. Existing permeable pavements lack anti-slip designs for slopes and are prone to overall displacement. Therefore, a permeable pavement block structure is needed to improve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a permeable paving block structure, comprising a base soil layer, wherein a plurality of water storage tanks are provided on the inner side of the base soil layer, a grid plate is provided on the upper end of the water storage tanks, a second purification layer is provided on the upper end of the grid plate, a soil layer is provided on the upper end of the second purification layer, a first purification layer is provided on the upper end of the soil layer, and a paving block layer is provided on the upper end of the first purification layer.

[0006] As a preferred embodiment of this utility model, the paving block layer has a cultivation groove in the center, the paving block layer is arranged in an I-shape, the middle part of both sides has a slot, and the two ends of both sides are fixed with protrusions. Two adjacent paving block layers are adapted to each other by the protrusions and the slots.

[0007] As a preferred embodiment of this utility model, the first purification layer is composed of aggregate with a particle size of [missing information] and a binder, wherein the aggregate is coarse sand or slag.

[0008] As a preferred embodiment of this utility model, the second purification layer is composed of aggregate with a particle size of a and a binder, wherein the aggregate is crushed stone or ceramsite.

[0009] As a preferred embodiment of this utility model, the water storage tank is provided with a guide pipe inside, and the surface of the guide pipe is provided with through holes.

[0010] As a preferred embodiment of this utility model, the soil layer is composed of a mixture of organic soil and water-retaining agent, and the grid plate is made of high-strength plastic or metal.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model enhances slope stability by using an I-shaped paving block layer with an interlocking structure of protrusions and grooves to effectively prevent slope paving slippage. The high-strength support characteristics of the grid plate can disperse slope stress and reduce the risk of soil erosion. The transverse setting of the water storage tank can intercept slope runoff and reduce water scouring force.

[0013] 2. This utility model optimizes slope drainage efficiency. The diversion pipe is arranged at an angle along the slope to accelerate drainage using gravity and prevent water accumulation. The double-layer purification layer uses aggregates of different particle sizes to ensure rapid water permeability on the slope while avoiding the loss of fine particles. The segmented setting of the water storage tank can effectively collect slope runoff and realize stepped drainage.

[0014] 3. This utility model is for slope ecological preservation. The soil layer is filled with a water-retaining agent to improve the water-holding capacity of the slope soil, which is conducive to vegetation growth. The stepped arrangement of the cultivation troughs forms a continuous vegetation belt, which enhances the slope soil stabilization capacity. The first purification layer effectively buffers the slope rainwater erosion and protects the surface soil. Attached Figure Description

[0025] Please see Figure 1-5 This utility model provides a technical solution: a permeable paving block structure, including a base soil layer 5, with several water storage tanks 7 arranged inside the base soil layer 5. A grid plate 6 covers the upper end of the water storage tanks 7, a second purification layer 4 is arranged above the grid plate 6, a soil layer 3 is arranged above the second purification layer 4, a first purification layer 2 is arranged above the soil layer 3, and a paving block layer 1 is arranged above the first purification layer 2. Rainwater first permeates downwards through the paving block layer 1 and enters the first purification layer 2. This layer is composed of aggregates such as coarse sand or slag, which can effectively filter larger particulate impurities in rainwater, while also mitigating water flow impact and preventing soil erosion from the soil layer 3.

[0026] As an example of this utility model, the paving block layer 1 has a cultivation trough 12 in the center. The paving block layer 1 is generally arranged in an I-shape, with slots 10 in the middle of both sides and protrusions 11 fixed at both ends. Two adjacent paving block layers 1 are adapted to each other by the protrusions 11 and the slots 10. The paving block layer 1 adopts an I-shaped design and achieves rapid splicing through the cooperation of the protrusions 11 and the slots 10, ensuring the stability of the overall structure and the convenience of construction. The grid plate 6 is made of high-strength plastic or metal, which can support the upper load and ensure water permeability. If the rainfall is large, some water can continue to infiltrate downward to the foundation soil layer 5 to replenish groundwater and achieve natural circulation.

[0027] As an example of this utility model, the first purification layer 2 is composed of aggregate with a particle size of [missing information] and a binder, wherein the aggregate is coarse sand or slag.

[0028] As an example of this utility model, the second purification layer 4 is composed of aggregate with a particle size of and a binder, wherein the aggregate is crushed stone or ceramsite.

[0029] As an example of this utility model, the water storage tank 7 is provided with a guide pipe 8 inside, and the surface of the guide pipe 8 is provided with a through hole 9. The purified water flows into the water storage tank 7. The tank is used to temporarily store rainwater to relieve the pressure of instantaneous rainfall. When the water level in the water storage tank 7 is too high, the excess water enters the pipe through the through hole 9 on the surface of the guide pipe 8 and is discharged into the municipal drainage system or recycled along the guide pipe 8 to avoid water accumulation.

[0030] As an example of this utility model, the soil layer 3 is composed of organic soil and water-retaining agent, and the grid plate 6 is made of high-strength plastic or metal. After preliminary purification, the rainwater continues to seep down into the soil layer 3, which is composed of organic soil and water-retaining agent. It can provide the plants in the cultivation tank 12 with the water and nutrients needed for growth. Excess water continues to seep down into the second purification layer 4, which is composed of gravel or ceramsite. It can further filter out fine suspended solids in the water and improve water quality.

[0031] Working principle: During use, rainwater first permeates downwards through the paving block layer 1 and enters the first purification layer 2. This layer is composed of aggregates such as coarse sand or slag, which can effectively filter larger particulate impurities in rainwater, while also slowing down the impact of water flow and preventing soil erosion from the soil layer 3.

[0032] After initial purification, the rainwater continues to seep down into the soil layer 3, which is a mixture of organic soil and water-retaining agent. This layer provides the plants in the cultivation trough 12 with the water and nutrients they need to grow. Excess water continues to seep down into the second purification layer 4, which is made of gravel or ceramsite. This layer can further filter out fine suspended solids in the water and improve water quality.

[0033] The purified water flows into the water storage tank 7, which is used to temporarily store rainwater and relieve the pressure of instantaneous rainfall. When the water level in the water storage tank 7 is too high, the excess water enters the pipe through the through hole 9 on the surface of the guide pipe 8 and is discharged into the municipal drainage system or recycled along the guide pipe 8 to avoid water accumulation.

[0034] The paving block layer 1 adopts an I-shaped design and achieves rapid splicing through the cooperation of protrusions 11 and slots 10, ensuring the stability of the overall structure and the convenience of construction. The grid plate 6 is made of high-strength plastic or metal, which can support the upper load and ensure water permeability. If the amount of rainwater is large, some water can continue to seep down to the subgrade layer 5 to replenish groundwater and achieve natural circulation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
