Description

Technical Field

[0001] The utility model relates to the technical field of road base, in particular to a new type of permeable PC brick for urban road base. Background Art

[0002] PC bricks are polycarbonate bricks, which are often used in the base layer of urban roads.

[0003] When current PC bricks are in use, their upper surface is stepped on by pedestrians for a long time. Since the soles of pedestrians' feet are in direct contact with the permeable micropores, the permeable micropores on the surface can easily be clogged with dust, affecting the water permeability. In addition, the PC bricks are independent of each other, which not only has poor installation stability, but also makes it easy for water under the PC to splash out from between the two PC bricks when stepping on a single PC brick.

[0004] To this end, we propose a new type of permeable PC brick for urban road base to solve the above problems. Utility Model Content

[0005] The utility model provides a new type of permeable PC brick for urban road base, which solves the technical problems of the existing PC bricks such as easy clogging of permeable micropores, unstable installation and easy splashing of dirty water when stepped on.

[0006] In order to solve the above technical problems, the utility model provides a new type of permeable PC brick for urban road base, including a brick body a and a brick body b. The brick body a and the brick body b are both provided with multiple permeable holes. The front and rear sides of the brick body a are provided with splicing outer grooves, and the front and rear sides of the brick body b are provided with splicing outer blocks. When the brick body a and the brick body b are spliced ​​together, the splicing outer blocks can be tightly inserted into the splicing outer grooves. The left and right sides of the brick body a are provided with matching sockets, and the left and right sides of the brick body b are provided with matching plugs that are compatible with the matching sockets.

[0007] Preferably, the splicing outer block and the matching insert block are both integrally formed with the brick body b.

[0008] Preferably, the water-permeable holes include water inlet holes located on the upper surfaces of brick body a and brick body b, water holes located inside, and drainage holes located on the lower surfaces, and the water inlet holes are connected to the water holes and the drainage holes.

[0009] Preferably, a protective ring is integrally formed on the upper surface of the brick body a and the brick body b. The protective ring is arranged at the water inlet and has a thickness of 4 mm.

[0010] Preferably, the water inlet and the drainage hole are both arranged in a vertical state, while the water hole is arranged at an angle.

[0011] Preferably, a splicing inner block is integrally formed on the splicing outer block, and a splicing inner groove adapted to the splicing inner block is provided in the splicing outer groove.

[0012] Preferably, a dovetail block is integrally formed on the mating plug-in block, and the mating socket is adapted to the overall shape of the mating plug-in block and the dovetail block.

[0013] Preferably, the surfaces of the brick body a and the brick body b are provided with a plurality of anti-slip recesses in a rectangular array, and the depth of the anti-slip recesses is 2 mm.

[0014] Compared with the related art, the new PC brick for urban road base layer provided by this utility model has the following advantages:

[0015] Beneficial effects:

[0016] 1. In the present invention, the upper surface of the water inlet is protected by a protective ring, and the soles of pedestrians cannot directly contact the water inlet, which helps to prevent the water inlet from being blocked by dust on the soles. At the same time, the anti-slip recess and the protective ring can also play a certain anti-slip effect, making it safer for pedestrians to walk on rainy days.

[0017] 2. In the present invention, the front and rear sides of brick body a and brick body b can be spliced ​​by using the splicing outer groove, splicing inner groove, splicing outer block and splicing inner block, while the left and right sides can be combined by using the matching socket and dovetail block. The adjacent brick body a and brick body b can be spliced ​​together, thereby ensuring the overall stability and avoiding the problem of sewage splashing when a single PC brick is stepped on.

[0023] Embodiment 1, by Figure 1-4A new type of permeable PC brick for urban road base layer is provided, including a brick body a1 and a brick body b2. Brick body a1 and brick body b2 are both provided with multiple permeable holes, and the permeable holes include a water inlet hole 5 located on the upper surface of brick body a1 and brick body b2, a water flow hole 12 located inside, and a drainage hole 13 located on the lower surface. The water inlet hole 5 is connected with the water flow hole 12 and the drainage hole 13. Water flows out through the water inlet hole 5, the water flow hole 12 and the drainage hole 13 in turn. The water inlet hole 5 and the drainage hole 13 are both set in a vertical state, while the water flow hole 12 is set at an angle, and the cross-section is circular, which is not easy to cause accumulation of particulate impurities.

[0024] The front and rear sides of the brick body a1 are provided with splicing outer grooves 3, and the front and rear sides of the brick body b2 are provided with splicing outer blocks 8. When the brick body a1 and the brick body b2 are spliced ​​together, the splicing outer block 8 can be tightly inserted into the splicing outer groove 3. The splicing outer block 8 is integrally formed with a splicing inner block 10, and the splicing outer groove 3 is provided with a splicing inner groove 9 adapted to the splicing inner block 10. The splicing outer block 8 and the splicing inner block 10 cooperate to form a T-shaped structure, and the splicing outer groove 3 and the splicing inner groove 9 are stepped to accommodate the splicing. The outer block 8 and the inner block 10 are connected together. The left and right sides of the brick body a1 are provided with matching sockets 4, while the left and right sides of the brick body b2 are provided with matching plugs 11 that match the matching sockets 4. The outer block 8 and the matching plugs 11 are integrally formed with the brick body b2. The matching sockets 4 on the brick body a1 are aligned with the matching plugs 11 on the brick body b2 and pushed flat until the end faces are flush. At this time, the outer block 8 and the inner block 10 are also inserted into the outer groove 3 and the inner groove 9 to complete the connection.
