Description

Technical Field

[0001] The utility model relates to the technical field of concrete pavement, in particular to an anti-clogging permeable concrete pavement structure. Background Art

[0002] Permeable concrete structure is an eco-friendly concrete structure with interconnected pores (porosity 10%-30%). It is widely used in permeable pavement in the fields of municipal and water conservancy projects. It has good social, environmental and ecological benefits. It is an excellent paving material for protecting groundwater, maintaining ecological balance and alleviating urban heat island effect. It is conducive to the healthy development of the human living environment and is of special importance in urban rainwater management and water pollution prevention and control.

[0003] After searching, the utility model with Chinese patent publication number CN212375655U discloses an anti-clogging colored permeable concrete pavement structure, including a surface protective agent, a permeable surface layer, a permeable plain surface layer, a graded coarse sand layer, a graded crushed stone layer and a rammed soil layer, the rammed soil layer is arranged on the upper surface of the graded crushed stone layer, the graded coarse sand layer is arranged on the upper surface of the graded crushed stone layer, the permeable plain surface layer is arranged on the upper surface of the graded coarse sand layer, and the permeable surface layer is arranged on the upper surface of the permeable plain surface layer.

[0004] Since there are mud, sand and fine particles in the water flow, they will enter the permeable concrete structure layer of the pavement with the water flow. As the use time increases, this will cause the pores of the permeable concrete structure to become blocked, causing the drainage capacity of the permeable concrete structure to gradually decrease with the extension of use time. Therefore, it is necessary to regularly maintain the permeability of the permeable concrete pavement structure, which greatly increases the maintenance cost. Utility Model Content

[0005] The utility model aims to provide an anti-clogging permeable concrete pavement structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blockage-proof permeable concrete pavement structure, including a base soil layer, characterized in that: a cushion layer is laid on the top of the base soil layer, a folded water guide plate is placed on the top of the cushion layer, the water guide plate is arranged in an inclined state, a collecting trough is installed on one side of the base soil layer, and one end of the water guide plate at the bottom extends into the collecting trough, a plurality of equally spaced dispersed holes are opened at the bottom of the outer wall around the collecting trough, a filter frame is placed on the inner wall at the bottom of the collecting trough, and the filter frame is located directly below the water guide plate.

[0007] The mixture of rainwater and sediment is quickly conducted away, and the sediment can be collected to prevent sediment from accumulating in the pores of the concrete structure and causing blockage. The water flow and fine sediment particles fall onto the water guide plate, and the sediment is driven by the water flow along the slope of the water guide plate to the filter frame of the collection trough. The sediment is blocked by the filter frame, and the rainwater will pass through the filter holes to flow into the collection trough and be temporarily stored, and then flow out from multiple dispersed holes, and finally be slowly absorbed by the base soil layer.

[0008] As a further preferred embodiment of the present technical solution, a reinforcement net is placed on the top of the water guide plate, and a permeable concrete pavement is arranged on the top of the reinforcement net.

[0009] As a further preferred embodiment of the technical solution, a coarse-pore concrete layer is laid on the top of the reinforcement mesh, and a fine-pore concrete layer is laid on the top of the coarse-pore concrete layer.

[0010] As a further preferred embodiment of the present technical solution, the aggregate particles inside the coarse-pore concrete layer are larger than the aggregate particles in the fine-pore concrete layer.

[0011] When it rains, rainwater will first fall on the top of the fine-pore concrete layer, preventing larger sand and gravel particles from passing through its pores, thus preventing these sand and gravel particles from accumulating into the permeable concrete layer. However, rainwater can pass through the fine-pore concrete layer and then enter the coarse-pore concrete layer. Due to its larger pores, water can flow through faster.

[0012] As a further preferred embodiment of the present technical solution, the cushion layer is composed of crushed stone particles.

[0013] As a further preferred embodiment of the present technical solution, the reinforcement mesh is a steel mesh.

[0014] The utility model provides an anti-clogging permeable concrete pavement structure, which has the following beneficial effects:

[0015] (1) The utility model provides a water guide plate, a collection trough and a filter frame, so that the mixture of rainwater and silt can be quickly conducted out, and the silt can be collected to prevent the silt from accumulating in the pores of the concrete structure and causing blockage. The water flow and fine particles of silt fall on the water guide plate, and the silt is driven by the water flow to fall into the filter frame of the collection trough along the slope of the water guide plate. The silt is blocked by the filter frame, and the rainwater flows through the filter holes into the collection trough and is temporarily stored, and then flows out from multiple dispersed holes and is finally slowly absorbed by the base soil layer.

[0016] (2) The utility model provides a coarse-pore concrete layer and a fine-pore concrete layer. When it rains, rainwater will first fall on the top of the fine-pore concrete layer, making it impossible for larger sand and gravel particles to pass through its pores, thereby preventing these sand and gravel particles from accumulating and entering the permeable concrete layer. However, rainwater can pass through the fine-pore concrete layer and then enter the coarse-pore concrete layer. Since the pores of the coarse-pore concrete layer are larger, water can flow through faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: as shown in Figure 1 and Figure 2 As shown, in the present embodiment, a blockage-proof permeable concrete pavement structure includes a base soil layer 1, characterized in that: a cushion layer 2 is laid on the top of the base soil layer 1, a folded water guide plate 3 is placed on the top of the cushion layer 2, the water guide plate 3 is arranged in an inclined state, a collecting trough 4 is installed on one side of the base soil layer 1, and one end of the water guide plate 3 at the bottom extends into the collecting trough 4, a plurality of equally spaced dispersed holes 6 are opened on the bottom of the outer wall around the collecting trough 4, a filter frame 5 is placed on the inner wall at the bottom of the collecting trough 4, and the filter frame 5 is located directly below the water guide plate 3.

[0024] The water flow and fine particles of sediment fall onto the water guide plate 3, and the sediment is driven by the water flow and falls along the slope of the water guide plate 3 into the filter frame 5 of the collection tank 4. The sediment is blocked by the filter frame 5, and the rainwater passes through the filter holes and flows into the collection tank 4 to be temporarily stored, and then flows out from multiple dispersion holes 6, and is finally slowly absorbed by the base soil layer 1.

[0025] like Figure 3 and Figure 4As shown, a reinforcing mesh 7 is placed on the top of the water guide plate 3, and a permeable concrete pavement is arranged on the top of the reinforcing mesh 7. The reinforcing mesh 7 is a steel mesh, which can improve the overall strength of the concrete pavement.

[0026] As shown in FIG. 1 and FIG. 2 , a coarse-porous concrete layer 8 is laid on the top of the reinforcement mesh 7 , and a fine-porous concrete layer 9 is laid on the top of the coarse-porous concrete layer 8 .

[0027] The aggregate particles in the coarse-pore concrete layer 8 are larger than those in the fine-pore concrete layer 9 .

[0028] When it rains, rainwater will first fall on the top of the fine-pored concrete layer 9, preventing larger sand and gravel particles from passing through its pores, thus preventing these sand and gravel particles from accumulating into the permeable concrete layer. However, rainwater can pass through the fine-pored concrete layer 9 and then enter the coarse-pored concrete layer 8. Due to its larger pores, water can flow through faster.

[0029] As shown in FIG. 1 and FIG. 2 , the cushion layer 2 is composed of crushed stone particles, which can increase the strength and stability of the road surface and improve the drainage performance.

[0030] The utility model provides an anti-blocking permeable concrete pavement structure, and the specific working principle is as follows:

[0031] When it rains, rainwater will first fall on the top of the fine-pored concrete layer 9, making it impossible for larger sand and gravel particles to pass through its pores, thus preventing these sand and gravel particles from accumulating into the permeable concrete layer. However, rainwater can pass through the fine-pored concrete layer 9 and then enter the coarse-pored concrete layer 8. Due to its larger pores, the water flow can pass through faster. Finally, these water flows and fine particles of sediment are concentrated and fall on the water guide plate 3. The sediment is driven by the water flow and falls along the slope of the water guide plate 3 into the filter frame 5 of the collection trough 4. The sediment is blocked by the filter frame 5, and the rainwater will pass through the filter holes and flow into the collection trough 4 to be temporarily stored, and then flow out from multiple dispersed holes 6, and finally be slowly absorbed by the base soil layer 1.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
