Description

Technical Field

[0001] This utility model relates to the field of municipal road structures, and in particular to a municipal road designed to prevent water accumulation. Background Technology

[0002] Currently, urban roads are divided into pedestrian roads and motor vehicle roads. Motor vehicle roads are generally constructed by pouring a sufficient amount of concrete to form a concrete layer. However, due to the poor permeability of the concrete layer, surface water cannot seep into the underlying soil. Therefore, drainage wells are usually installed on both sides of the motor vehicle road. Surface water flows into the drainage wells according to the road's slope, and then flows through underground permeable pipe networks to rainwater treatment plants for recycling. Pedestrian roads are generally constructed of bricks. Pedestrian roads and motor vehicle roads usually share the same drainage system. Therefore, pedestrian roads are generally inclined at a certain angle to ensure that rainwater accumulated on the pedestrian road flows into the drainage wells on the motor vehicle road according to the road's slope. The lateral slope should generally not be less than 1% to ensure smooth drainage of rainwater.

[0003] Over time, the bricks on sidewalks often become loose, creating gaps between them. Since the road cannot drain water on its own, water accumulates at the bottom of the bricks. When pedestrians step on the bricks, dirty water splashes up and soils their clothes. To address this problem, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a municipal road that prevents water accumulation, in order to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A flood-proof municipal road includes a highway and a sidewalk. The sidewalk has several curb stones on both sides, which are joined together. The highway and the sidewalk are separated by the curb stones. One end of each curb stone is inserted into the ground, and the other end is positioned above ground. Rainwater wells are spaced along the highway. The sidewalk consists of a surface layer, a bonding layer, a base layer, and a subbase layer from top to bottom. Several capillary tubes are inserted vertically into the top of the bonding layer, with their bottoms contacting the base layer. The capillary tubes are arranged in an array. Several permeable pipes (first type) are installed on the top of the base layer, all arranged longitudinally. Several permeable pipes (second type) are also installed inside the base layer, all arranged horizontally. Each permeable pipe (second type) is installed at the bottom of a permeable pipe (first type), with one end connected to a curb stone. Drainage holes corresponding to the permeable pipes (second type) are provided on the curb stone.

[0007] Preferably, a retaining strip is provided on one side wall of the curbstone, and a retaining groove adapted to the retaining strip is provided on the other side wall of the curbstone. The curbstone on one side is engaged with the retaining strip and the retaining groove of the curbstone on the other side.

[0008] Preferably, the thickness of the base layer on the side away from the road is greater than the thickness on the side closer to the road, the surface layer is inclined, and the surface layer is divided into a high point and a low point by its inclined structure. The low point of the surface layer is located on the side closer to the road, and the height of the low point of the surface layer is level with the height of the curb stone.

[0009] Preferably, the second permeable pipe is an inclined structure corresponding to the base layer.

[0010] Preferably, the drainage hole is an inclined through structure, with the higher part of the drainage hole corresponding to the second permeable pipe and the lower part of the drainage hole corresponding to the top surface of the road.

[0011] Preferably, the surface layer adopts a permeable brick splicing structure, and permeable mortar is filled between each permeable brick. The bonding layer adopts a permeable mortar layer, the base layer adopts a permeable concrete structure, and the subbase adopts a coarse sand structure.

[0012] Beneficial effects: By designing the sidewalk to prevent water accumulation, the slope of the sidewalk allows rainwater to flow towards the side closer to the road and drain away through storm drains on the road. When rainwater reaches the top layer of the sidewalk, the permeable material of the surface layer allows it to infiltrate downwards, preventing water accumulation on the sidewalk surface. After infiltrating the surface layer, the rainwater enters the bonding layer, which is also made of permeable material, allowing it to continue infiltrating downwards. Capillaries installed in the bonding layer allow the rainwater to quickly infiltrate downwards. These capillaries correspond to permeable pipes, and through these two pipes, most of the infiltrated rainwater flows towards the curb. Drainage holes on the curb allow the infiltrated rainwater to be discharged towards the road. A small portion of the rainwater that enters the permeable pipes will infiltrate downwards through the permeable structure of the base layer, thus preventing water accumulation on the road surface.

[0020] See Figures 1 to 6 As shown, a water-proof municipal road includes a highway 1 and a sidewalk 2. Both sides of the sidewalk 2 are provided with several curb stones 3, which are spliced ​​together. The highway 1 and the sidewalk 2 are separated by the curb stones 3. One end of each curb stone 3 is inserted into the ground, and the other end of the curb stone 3 is set on the ground. Rainwater wells 4 are provided at intervals on the highway 1. During the paving of the sidewalk 2, the curb stones 3 are first laid on both sides according to the width of the sidewalk 2 to facilitate the subsequent laying of each layer of materials of the sidewalk 2.

[0021] A retaining strip 32 is provided on one side wall of the curbstone 3, and a groove 33 adapted to the retaining strip 32 is provided on the other side wall of the curbstone 3. During the installation process, the curbstone 3 on one side is first engaged with the groove 33 on the other side of the curbstone 3 through the retaining strip 32. Each curbstone 3 is assembled through the retaining strip 32 and the groove 33, making the installation of each curbstone 3 more tight and stable. When the curbstone 3 is installed to the designed edge of the sidewalk 2, the retaining strip 32 or groove 33 on the edge of the curbstone 3 will be exposed on the roadside. Therefore, the retaining strip 32 on one side can be cut off from the curbstone 3 and installed into the groove 33 on the other side of the curbstone 3. This can improve the aesthetics of the sidewalk 2 and also improve the safety of the sidewalk 2, preventing the protruding retaining strip 32 from causing safety hazards when pedestrians are not paying attention.

[0022] The sidewalk 2 consists of, from top to bottom, a surface layer 21, a bonding layer 22, a base layer 23, and a subbase layer 24. Each layer uses materials with different properties to improve the sidewalk 2's water resistance. The surface layer 21 uses a permeable brick splicing structure, which is the most common material in the sidewalk 2 and directly contacts pedestrians. It has good permeability and slip resistance. Permeable mortar is filled between the permeable bricks, and permeable grout is used to fill the gaps between the bricks. These materials enhance permeability and fix the permeable bricks, preventing them from shifting. The bonding layer 22 is a permeable mortar layer, with a bonding structure designed between the permeable bricks and the base layer 23. Layer 22 is used to enhance the bonding strength between the bricks and the base layer 23. It is made of permeable cement grout, which also ensures that when rainwater flows through the permeable bricks to the bonding layer 22, the bonding layer 22 can quickly infiltrate the rainwater downwards. The base layer 23 is made of permeable concrete, which has good permeability and load-bearing capacity and can effectively promote the infiltration of rainwater. The subbase layer 24 is made of coarse sand. Under the base layer 23, a layer of medium or coarse sand is usually laid as the subbase layer 24 to level and drain the water. Through the permeable structure of each layer of the sidewalk 2, rainwater can infiltrate downwards layer by layer, preventing water accumulation in the sidewalk 2.

[0023] The thickness of the base layer 23 on the side away from the highway 1 is greater than the thickness on the side closer to the highway 1. The surface layer 21 is set in an inclined shape. The surface layer 21 is divided into a high point and a low point by its inclined structure. The low point of the surface layer 21 is located on the side closer to the highway 1. The height of the low point of the surface layer 21 is level with the height of the curb stone 3. By designing the surface layer 21 in an inclined structure, rainwater can flow towards the highway 1 through the slope, improving the drainage of the sidewalk 2 and reducing water accumulation on the surface of the sidewalk 2.

[0024] Several capillary tubes 221 are inserted at the top of the bonding layer 22. The capillary tubes 221 are vertically arranged and their bottoms are in contact with the base layer 23. The capillary tubes 221 are arranged in an array. By installing several capillary tubes 221 in the bonding layer 22, several through holes can be generated in the bonding layer 22. When rainwater seeps into the bonding layer 22, the bonding layer 22 can more quickly allow the rainwater to seep downwards, preventing rainwater from accumulating at the bottom of the permeable brick and causing water accumulation. Several permeable pipes 231 are installed on the top of the base layer 23, all arranged longitudinally. Several permeable pipes 232 are also installed inside the base layer 23, all arranged transversely. Each permeable pipe 232 is installed at the bottom of the permeable pipes 231, with one end connected to the curbstone 3. The curbstone 3 has drainage holes 31 corresponding to the permeable pipes 232. When there is heavy rainfall, the base layer 23 cannot quickly drain the rainwater downwards after it seeps into it. Therefore, the permeable pipes 231 buried within the base layer 23 can drain the water that has not been drained in time. The infiltrated rainwater is collected, and the rainwater entering the first permeable pipe 231 flows into the second permeable pipe 232. The second permeable pipe 232 is an inclined structure corresponding to the base layer 23. The lower end of the second permeable pipe 232 corresponds to the drainage hole 31. The rainwater in the second permeable pipe 232 can be quickly discharged into the drainage hole 31 of the curb stone 3 by gravity. The drainage hole 31 is an inclined through structure. The upper part of the drainage hole 31 corresponds to the second permeable pipe 232, and the lower part of the drainage hole 31 corresponds to the top surface of the road 1. The rainwater is discharged into the road 1 through the drainage hole 31, and the rainwater can be collected through the rainwater well 4 of the road 1.

[0025] Both permeable pipe 1 231 and permeable pipe 2 232 adopt a structure with steel wire lining and geotextile nonwoven fabric wrapped around the outside. The geotextile nonwoven fabric structure can effectively filter and prevent sediment from entering the pipe. Permeable pipe 1 231 adopts a flat structure. The flat structure of permeable pipe 1 231 can better collect rainwater and correspond to the capillary 221 at the top.
