Description

Technical Field

[0001] The utility model relates to the technical field of garden pavement construction, in particular to a garden permeable pavement structure. Background Art

[0002] Garden roads organize space, guide tours, connect traffic, and provide places for strolls and rest. Like veins, they connect the various scenic areas of the garden into a whole. Garden roads themselves are an integral part of the garden landscape. The winding curves, rich meanings, and exquisite patterns all give people a beautiful enjoyment. Therefore, garden roads are an integral part of the garden and an important part of garden design. The requirements for garden road paving are also relatively high.

[0003] At present, most garden roads are paved with paving bricks. However, due to the uneven construction quality and the subsequent rolling and trampling after being soaked in rainwater, hollows can easily form under the paving bricks. When pedestrians step on them, the paving bricks will collapse. In addition, when there is rainwater in the hollows, it is easy for pedestrians to step on them and cause muddy water in the hollows to splash out. In the worst case, it will cause damage to pedestrians' clothes, and in the worst case, it will cause pedestrian injuries, seriously affecting pedestrian safety. Therefore, it is very necessary to design a permeable pavement structure with strong supporting capacity to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The utility model provides Figures 1 to 8The first embodiment of a permeable garden pavement structure shown in FIG. 1 includes a roadbed 1, hollow curbstones 4 laid on both sides of the roadbed 1, and a brick layer 3 laid above the roadbed 1. Drain holes 5 are provided on the side of the curbstone 4 near the brick layer 3, and filters are provided inside the drainage holes 5. A support layer 2 is laid between the roadbed 1 and the brick layer 3. The roadbed 1 includes, from bottom to top, a rammed earth layer 101, a crushed stone cushion layer 102, and a permeable concrete layer 103. The support layer 2 is laid on the permeable concrete layer 103.

[0032] The supporting layer 2 includes a plurality of transverse beams 201 and a plurality of longitudinal beams 202. The ends of the transverse beams 201 are respectively connected to the interior of the curb 4. A connecting assembly 6 is provided between the ends of the longitudinal beams 202 and two adjacent transverse beams 201. A plurality of cells 203 are formed between two adjacent transverse beams 201 and two adjacent longitudinal beams 202. The cells 203 are filled with a permeable concrete layer 103.

[0033] The interior of the crossbeam 201 and the longitudinal beam 202 are both provided with a water trough 205 with an open top along the length direction. The crossbeam 201 is connected to the water trough 205 on the longitudinal beam 202, and a porous filter plate 204 is provided at the upper opening of the water trough 205. A connecting hole is provided on the side of the curb 4 close to the supporting layer 2. The two ends of the longitudinal beam 202 are respectively inserted into the connecting holes on the curb 4 on both sides, and the water trough 205 on the longitudinal beam 202 is connected to the interior of the curb 4 through the connecting holes. The middle part of the inner bottom wall of the water trough 205 on the longitudinal beam 202 is higher than the height of the two ends.

[0034] The paving brick layer 3 includes a plurality of permeable bricks 301, which are laid on a plurality of cells 203. A brick gap is left between two adjacent permeable bricks 301. The brick gap is located directly above the porous filter plate 204, and the interior of the brick gap is filled with a permeable caulking material 302.

[0035] A plurality of positioning protrusions 3011 are provided on the lower surface of the permeable brick 301 . The positioning protrusions 3011 are inserted into the cells 203 , and the plurality of positioning protrusions 3011 are respectively in contact with the inner surface of the cells 203 .

[0036] Working principle: When laying, first tamp the ground into a rammed earth layer 101, then lay a crushed stone cushion layer 102 and a permeable concrete layer 103 on the rammed earth layer 101 in sequence, then lay the support layer 2 on the permeable concrete layer 103, and ensure that the two ends of the beam 201 are respectively inserted into the connecting holes in the curb 4, and ensure that the water flow channel 205 on the beam 201 is connected with the inside of the curb 4, then lay the permeable concrete layer 103 in the cells 203 in the support layer 2, and finally lay the permeable bricks 301 in sequence. On the cell 203, ensure that one permeable brick 301 corresponds to one cell 203. During the paving process, ensure that the positioning protrusion 3011 on the lower part of the permeable brick 301 abuts the inner surface of the cell 203, so that the permeable brick 301 can be positioned and fixed in the horizontal direction. After the paving brick layer 3 is laid, the brick joints between the permeable bricks 301 can be filled with permeable caulking material 302, such as quartz sand caulking material. After filling, the permeable caulking material 302 is separated from the water flow channel 205 below by the porous filter plate 204.

[0037] After the pavement structure is paved, the support layer 2 supports each permeable brick 301, thereby improving the stability of the road brick layer 3, thereby effectively preventing the bottom of the permeable brick 301 from hollowing out. Due to the stable support, the permeable brick 301 can also be effectively prevented from collapsing and shaking when stepped on.

[0038] Moreover, during rainy weather, part of the rainwater seeps into the ground through the permeable bricks 301, the permeable concrete layer 103 and the gravel cushion layer 102 in sequence, while the other part can seep into the water troughs 205 on the crossbeams 201 and the longitudinal beams 202 in sequence through the permeable filling materials 302 and the porous filter plates 204 in the brick joints between the permeable bricks 301. The rainwater entering the water trough 205 on the longitudinal beam 202 flows into the water trough 205 on the crossbeam 201, and finally flows along the slope of the bottom wall of the water trough 205 on the crossbeam 201 to the curbstones 4 on both sides, thereby further improving the drainage capacity and preventing the brick joints from being soaked.

[0039] The utility model provides Figures 8 and 9 The second embodiment of a garden permeable pavement structure shown is as follows: the connecting component 6 includes an annular groove 601 opened at the end of the longitudinal beam 202 and an interface 602 opened on the cross beam 201. The interface 602 is U-shaped, the end of the longitudinal beam 202 is inserted into the interior of the interface 602, and the inner ring of the interface 602 is inserted into the interior of the annular groove 601.

[0040] Working principle: When laying the support layer 2, several cross beams 201 can be laid on the permeable concrete layer 103 in sequence along the length of the road. During the laying process, ensure that the two ends of the cross beam 201 are respectively inserted into the connecting holes on the curb 4, and then each longitudinal beam 202 is installed between two adjacent cross beams 201. During installation, ensure that the annular groove 601 on the longitudinal beam 202 is inserted into the interface 602 on the cross beam 201 from top to bottom, and ensure that the annular groove 601 and the interface 602 are buckled with each other, so that the cross beam 201 and the longitudinal beam 202 can be firmly connected. After all the cross beams 201 and the longitudinal beams 202 are installed, the laying of the support layer 2 is completed.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
