Description

Technical Field

[0001] The utility model relates to the field of road construction, and particularly relates to a permeable sidewalk. Background Art

[0002] Road construction refers to the reconstruction, maintenance and new construction of existing roads to improve the bearing capacity and service level of roads, ensure traffic safety and smoothness. The sidewalk is also one of the many projects in road construction. The sidewalk refers to a road dedicated for pedestrians, with a width of about four meters generally. It is constructed according to urban planning and is divided into several parts such as the curb, the accessory facility functional zone, the blind path, the sidewalk, and the setback line. The sidewalk plays an important role in the city. It not only facilitates the passage of pedestrians but also connects the city. It is an important part of urban traffic. The materials of the sidewalk can include various types, such as asphalt concrete, cast-in-place cement concrete, precast cement concrete slabs, granite paving slabs, etc. The selection of these materials depends on the specific urban planning and design requirements.

[0003] After retrieval, a deformation-resistant pedestrian road surface structure with the publication number CN210975420U specifically discloses a deformation-resistant pedestrian road surface structure. The pedestrian road surface structure includes a road surface structure body, a permeable concrete layer, a steel bar layer, a sandy soil layer and a water storage layer. The permeable concrete layer, the steel bar layer, the sandy soil layer and the water storage layer are arranged from top to bottom in sequence. The steel bar layer includes a honeycomb-shaped steel bar structure. The upper and lower surfaces of the honeycomb-shaped steel bar structure are both honeycomb-shaped. A first filler is arranged in the honeycomb-shaped steel bar structure. The honeycomb-shaped steel bar structure is more material-saving on the basis of stability. If a heavy object is above the sidewalk and presses downwards, the honeycomb-shaped steel bar structure will support the road surface and reduce the deformation of the pedestrian road surface. The utility model has the following beneficial effects: The honeycomb-shaped steel bar structure supports the road surface, reduces the deformation of the pedestrian road surface caused by the upper pressure, and increases the deformation resistance of the pedestrian road surface.

[0004] During the use of the existing permeable sidewalk, since the permeable sidewalk allows rainwater to accumulate briefly on the paving surface and then slowly infiltrate into the roadbed or drain into the nearby soil, but if the rainfall is too large and exceeds the saturation of the soil and the permeable sidewalk itself, and there is a lack of a method for water storage and drainage, it will cause water accumulation and even backflow on the permeable sidewalk surface. Moreover, the sidewalk in the above comparative case also lacks the ability of water storage and drainage. Such long-term use increases the loss of the permeable sidewalk and also causes a certain waste of rainwater.

[0005] Therefore, it is necessary to invent a permeable sidewalk to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a permeable sidewalk. Through a water storage layer, a water storage tank, a water passage opening, a permeable water storage pool, fixing bolts, a spaced filter screen and a permeable lower layer, the permeable sidewalk is enabled to have the ability of water storage and drainage. At the same time, the rainwater filtered and stored by the spaced filter screen can be used for irrigation of surrounding trees in the permeable water storage pool or pumped to other environments through an external water pump. In this way, the permeable sidewalk makes full use of rainwater resources and reduces waste, and it is also convenient to clean the surface of the permeable sidewalk after rainy weather, reducing the loss of the permeable sidewalk, so as to solve the problem that in the prior art, during the use of the permeable sidewalk, since the permeable sidewalk allows rainwater to accumulate briefly on the pavement and then slowly infiltrate into the roadbed or drain into the nearby soil, but if the rainfall is too large and exceeds the saturation of the soil and the permeable sidewalk itself, there is a lack of a method for water storage and drainage, which will cause water accumulation or even backflow on the surface of the permeable sidewalk. Moreover, the sidewalk in the above comparative case also lacks the ability of water storage and drainage.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0028] The present utility model provides a permeable sidewalk as shown in Figures 1-5 Figure, which includes outer road soil 1 for excavating and laying the main body of the permeable sidewalk;

[0029] Sidewalk subbase 2 is arranged at the inner bottom layer of outer road soil 1 for bearing the load of the permeable sidewalk surface. A water cushion gravel base 3 is attached above sidewalk subbase 2, a concrete base 4 is attached above water cushion gravel base 3, a waterproof protective layer 5 is pasted on the surface of concrete base 4, and a water storage layer 6 is arranged above concrete base 4;

[0030] Water storage tank 7 is arranged inside water storage layer 6 for storing rainwater seeping down from above. A water passage opening 8 is fixedly installed on one side of water storage tank 7, a permeable water storage pool 9 is arranged on the other side of water passage opening 8, a fixed bolt 10 penetrates through the outside of permeable water storage pool 9, and one end of fixed bolt 10 is movably connected with a spacing filter screen 11;

[0031] The permeable lower layer 12 is arranged above the water storage layer 6 and is used to assist the rainwater on the permeable sidewalk to penetrate downward. A fixed enclosure 13 is fixedly installed above the permeable lower layer 12, and permeable bricks 14 are arranged inside the fixed enclosure 13. If the rainfall is too heavy, the rainwater will penetrate downward through the permeable lower layer 12 into the water storage tank 7 of the water storage layer 6 for temporary storage, thus avoiding situations such as backflow of rainwater due to the saturation of the permeable sidewalk. Then, as the rain continues, the rainwater will flow into the permeable water storage pool 9 through the water passage openings 8 on both sides of the water storage tank 7 for storage. In this way, the upper limit of water permeability, water seepage, and water diversion of the permeable sidewalk is greatly improved, enabling the permeable sidewalk to have the ability of water storage and water diversion.

[0032] As Figure 1 , Figure 2 and Figure 3 shown, the concrete base layer 4 and the waterproof protective layer 5 are closely attached. The material of the waterproof protective layer 5 is Portland cement. The concrete base layer 4 is below the water storage layer 6 through the waterproof protective layer 5, enabling the bottom base layer of the permeable sidewalk to have good waterproof ability and preventing rainwater from continuing to penetrate downward through the water storage layer 6, thus affecting the stability of the bottom base layer of the permeable sidewalk. The water passage opening 8 is fixedly connected to the water storage tank 7, and the spaced filter screen 11 is threadedly connected to the permeable water storage pool 9. As the rain continues, the rainwater will flow into the permeable water storage pool 9 through the water passage openings 8 on both sides of the water storage tank 7 for storage, completing the diversion of rainwater. The permeable lower layer 12 is fixedly connected to the water storage layer 6, and the permeable bricks 14 are evenly distributed on the fixed enclosure 13. The permeable bricks 14 are above the permeable lower layer 12 and are used to assist the permeable lower layer 12 in penetrating the rainwater above.

[0033] As Figure 1 , Figure 4 and Figure 5 shown, an upper permeable surface layer 15 is attached to the upper part of the permeable brick 14. Anti-slip I-shaped ribs 16 are provided on the surface of the upper permeable surface layer 15. Sidewalk edges 17 are fixedly installed on both sides of the upper permeable surface layer 15. The multiple groups of anti-slip I-shaped ribs 16 on the upper permeable surface layer 15 enhance the friction between the permeable sidewalk and the soles of pedestrians' feet in rainy weather, reducing the probability of pedestrians slipping due to the wet and slippery surface of the permeable sidewalk in rainy weather. The number of anti-slip I-shaped ribs 16 is set to be multiple, and the multiple anti-slip I-shaped ribs 16 are evenly distributed on the upper permeable surface layer 15. The anti-slip I-shaped ribs 16 are arranged above the upper permeable surface layer 15, and when blind people pass by, the concave and convex strips can also provide certain assistance for blind people to detect the road surface.

[0034] Working principle of this utility model: First, during road construction, according to the specified range and size of the permeable sidewalk, the outer road soil 1 is excavated. At the bottom of the outer road soil 1, a sidewalk subgrade 2 is laid with a rammer. Then, a water cushion gravel base course 3 and a concrete base course 4 are successively laid on the sidewalk subgrade 2 to complete the laying work of the permeable sidewalk base course. The concrete base course 4 is below the waterproof protective layer 5 and above the water storage layer 6, enabling the bottom base course of this permeable sidewalk to have good waterproof ability and preventing rainwater from continuously seeping downward through the water storage layer 6, thus affecting the stability of the bottom base course of the permeable sidewalk. Next, a water storage layer 6 and a permeable lower surface layer 12 are laid above the concrete base course 4. Then, a fixed enclosure 13 is taken out and nailed to the permeable lower surface layer 12. Subsequently, permeable bricks 14 are stacked inside the fixed enclosure 13 in sequence according to the laying requirements of the permeable sidewalk. The permeable bricks 14 are above the permeable lower surface layer 12 and are used to assist the permeable lower surface layer 12 in permeating the rainwater above. Finally, a permeable surface layer 15 is laid to complete the construction and laying work of this permeable sidewalk. When this permeable sidewalk is used in rainy weather, if the rainfall is too heavy, the rainwater will permeate downward through the permeable lower surface layer 12 into the water storage tank 7 of the water storage layer 6 for temporary storage, thus preventing the rainwater from flowing back due to the saturation of the permeable sidewalk. Then, as the rain continues, the rainwater will flow into the permeable water storage pool 9 through the water channels 8 on both sides of the water storage tank 7 for storage. This greatly improves the upper limit of the water permeability, water seepage, and water diversion of the permeable sidewalk, enabling this permeable sidewalk to have the ability of water storage and water diversion. Then, the rainwater filtered and stored by the spaced filter screen 11 can be pumped out by an external water pump in the permeable water storage pool 9 for irrigation of surrounding trees or pumped to other environments for use. Subsequently, during rain, multiple groups of anti-slip I-shaped ribs 16 on the upper permeable surface layer 15 enhance the friction between the permeable sidewalk and the soles of pedestrians' feet in rainy weather, reducing the probability of pedestrians slipping due to the wet and slippery surface of the permeable sidewalk in rainy weather. Finally, after completing all the installation and use work of the permeable sidewalk according to the above operations, the permeable sidewalk can be maintained daily. The material of the waterproof protective layer 5 is: Portland cement. Thus, the use process of this permeable sidewalk is completed.

[0035] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
