Description

Technical Field

[0001] This utility model relates to the field of road design technology, specifically to a road design splicing pavement. Background Technology

[0002] In the design of non-motorized vehicle roads, interlocking pavement systems are common. However, during use, there are many gaps in the interlocking pavement. Rainwater or dust can easily enter through these gaps and accumulate at the bottom of the pavement slab. Excessive water accumulation can cause the pavement foundation to loosen and the pavement to settle. This is a major defect of interlocking pavement compared to traditional road pavement. Furthermore, existing drainage systems cannot effectively drain water from pavement with many gaps in rainy weather.

[0003] Therefore, there is an urgent need to design a non-motorized vehicle road splice pavement with drainage function. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a road design for spliced ​​pavement.

[0005] The technical solution of this utility model is: a road design splicing pavement, including a surface pavement panel and a bottom support base. The support base has a horizontal drainage groove, a vertical first protrusion on its front end face, a first groove that fits the first protrusion and runs vertically through it on its rear end face, and a longitudinal second groove on both the left and right ends of its top surface. Several of the support bases are arranged in a rectangular array on the roadbed. The drainage grooves are connected left and right to form a drainage channel arranged along the width of the pavement. Two adjacent second grooves on the left and right sides form a slot. The first protrusion on the front and rear contact surfaces is connected to the first groove.

[0006] The road surface slab has several through holes, and a limiting block adapted to the slot is provided at the center of its bottom; several road surface slabs are laid in a rectangular array on the bottom support base, and the limiting blocks are inserted into the corresponding slots.

[0007] Preferably, the cross-sections of the first protrusion and the first groove are both trapezoidal.

[0008] Preferably, the drainage channel is an inverted trapezoidal channel.

[0009] Preferably, it also includes a connecting rod, wherein a transverse insertion hole is provided at the center of the limiting block, and the connecting rod is inserted into the insertion hole of multiple road panels to connect a row of road panels arranged along the width of the road surface into one piece.

[0010] Preferably, the cross-sections of the socket and the connecting rod are both rectangular.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] This interlocking pavement consists of two layers. Rainwater can flow into the drainage channel in the lower layer through the holes on the pavement panel, and then flow to the green belts or rainwater wells on both sides of the road, thus achieving the drainage function and preventing water accumulation from affecting the foundation. The cooperation between the first protrusion and the first groove can prevent relative displacement of two adjacent rows of support seats in the lateral direction, and the cooperation between the limiting block and the slot can prevent relative displacement of two adjacent rows of support seats in the longitudinal direction. At the same time, it can realize the positioning and laying of the pavement panel, ensuring the stability of the interlocking pavement during use. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0019] Reference Figure 1-2 As shown, a road design for spliced ​​pavement includes a surface pavement panel 1 and a bottom support base 3. The support base 3 has a transverse drainage groove 301, a vertical first protrusion 302 on its front end face, a first groove 303 that fits the first protrusion 302 and runs vertically through it on its rear end face, and a longitudinal second groove 304 on both the left and right ends of its top surface. Several support bases 3 are arranged in a rectangular array on the roadbed. The drainage grooves 301 are connected left and right to form a drainage channel arranged along the width of the road surface. Two adjacent second grooves 304 on the left and right sides form a slot. The first protrusion 302 on the front and rear contact surfaces is connected to the first groove 303.

[0020] The road panel 1 has several through holes 101, and a limiting block 2 adapted to the card slot is provided at the bottom center; several road panels 1 are laid in a rectangular array on the bottom support base 3, and the limiting block 2 is inserted into the corresponding card slot.

[0021] More specifically, in this embodiment, the cross-sections of the first protrusion 302 and the first groove 303 are both trapezoidal, and the drainage groove 301 is an inverted trapezoidal groove.

[0022] After the spliced ​​road surface is laid, the cooperation between the first protrusion 302 and the first groove 303 can prevent the relative displacement of the two adjacent rows of support seats 3 in the lateral direction, and the cooperation between the limiting block 2 and the slot can prevent the relative displacement of the two adjacent rows of support seats 3 in the longitudinal direction. At the same time, it can realize the positioning and laying of the road panel 1, ensuring the stability of the spliced ​​road surface during use.

[0023] During use, rainwater flows through the through holes 101 on the pavement slab 1 into the lower drainage channel, and then flows through the drainage channel to the green belts or storm drains on both sides of the road, thus achieving the drainage function and preventing water accumulation from affecting the foundation. After a period of use, if a support 3 is damaged, the two pavement slabs 1 on its upper side can be removed, and the damaged support 3 can be lifted directly without disassembling and reassembling other support 3, effectively improving the efficiency of road maintenance. Example 2

[0024] As a preferred embodiment of this utility model, this embodiment adds a connecting rod 4 based on embodiment one, specifically:

[0025] Reference Figure 3-4 As shown, this embodiment also includes a connecting rod 4. A transverse insertion hole 201 is provided at the center of the limiting block 2. The connecting rod 4 is inserted into the insertion holes 201 of multiple road panels 1, connecting a row of road panels 1 arranged along the width of the road surface into one piece.

[0026] More specifically, both the socket 201 and the connecting rod 4 have rectangular cross-sections.

[0027] When it is necessary to clean up garbage and sediment in the drainage channel, the entire row of road panels 1 on the upper side of the drainage channel can be lifted by the connecting rod 4, which further improves the efficiency of road maintenance.

[0028] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
