Description

Technical Field

[0001] This utility model belongs to the field of hardened road technology and relates to a drainage structure for hardened roads. Background Technology

[0002] Hardened roads refer to unpaved roads such as dirt roads and gravel roads that have been transformed into hard surfaces with higher strength and durability through construction techniques. However, hardened roads suffer from poor permeability and drainage, making them prone to surface runoff and water accumulation during heavy rainfall. This not only affects traffic safety but also exacerbates the risk of urban flooding.

[0003] To address the aforementioned problems, various improvements have been made, some of which have even been patented. For example, Chinese patent literature discloses a low-cost village-connecting recycled base cement concrete drainage pavement structure [Patent No.: 201822201544.0; Authorization Announcement No.: CN209384055U]. This structure includes a full-thickness recycled base layer, a waterproof functional layer, a permeable cement concrete pavement, and drainage blind ditches set on both sides of the pavement, with the drainage blind ditches filled with gravel. The full-thickness recycled base layer is laid on the subgrade; the waterproof functional layer covers the full-thickness recycled base layer and extends to the inner side of the drainage blind ditches on both sides of the pavement; the permeable cement concrete pavement is laid on the waterproof functional layer and is higher than the top layer of the drainage blind ditches.

[0004] This type of cement concrete drainage pavement structure features a permeable cement concrete surface on top of the paved road, with drainage ditches on both sides filled with crushed stone. The top layer of crushed stone is 20cm lower than the permeable cement concrete surface. A full-thickness recycled base course has a 2% cross slope, sloping outwards from its centerline to ensure that seepage water drains into the drainage ditches. However, in this type of cement concrete drainage pavement structure, water can seep into the permeable cement concrete surface. The limited drainage speed of the permeable cement concrete surface leads to water accumulation within it. If drainage is not timely, efflorescence can occur, leaving white streaks on the paved road. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a drainage structure for hardened roads, and to solve the technical problem of how to accelerate the drainage speed of hardened roads.

[0006] The objective of this utility model can be achieved through the following technical solution: a drainage structure for a hardened road, the hardened road comprising a base concrete layer and a permeable concrete layer disposed on the base concrete layer, characterized in that the drainage structure comprises two first drainage pipes, several second drainage pipes, and several drainage wells located on both sides of the hardened road, the two first drainage pipes being embedded along the length of the hardened road on both sides of the permeable concrete layer, one end of the second drainage pipe being connected to the first drainage pipe and the other end being adjacent to the corresponding drainage well, several through first drainage holes being arranged on the pipe wall of the first drainage pipe, and a first wire mesh being tightly wrapped on the outer wall of the first drainage pipe, the mesh aperture of the first wire mesh being smaller than the aperture of the first drainage holes.

[0007] When it rains, water can permeate into the permeable concrete layer. Some water enters the first drainage pipe through the mesh of the first wire mesh and the first drainage hole, and then flows to the drainage well through the second drainage pipe. The remaining water flows to the drainage well through the permeability of the permeable concrete layer itself, thus achieving drainage. The permeability of the permeable concrete layer is limited. Two first drainage pipes are embedded along the length of the paved road on both sides of the permeable concrete layer. This allows water flowing to both sides of the permeable concrete layer to enter the first drainage pipe through the mesh of the first wire mesh and the first drainage hole, accelerating water flow while reducing moisture in the permeable concrete layer. This allows the permeable concrete layer to better absorb moisture from the ground, accelerating the drainage speed of the paved road and preventing efflorescence. The mesh diameter of the first wire mesh is smaller than the diameter of the first drainage hole, preventing concrete and other impurities from clogging the first drainage hole and the first and second drainage pipes, ensuring drainage speed. At the same time, the first wire mesh tightly wraps around the outer wall of the first drainage pipe, supporting it and preventing damage. The first wire mesh is fixed to the outside of the first drainage pipe by binding and clamping to ensure it remains tightly attached and does not shift during construction. The permeable concrete layer is a porous concrete structure composed of single-grade coarse aggregate, cement, water, and admixtures. The thickness of the permeable concrete layer is 5-10cm, adjusted according to the road load level. The thickness of the base concrete layer is 15-30cm, with a compaction density of not less than 96%, used to improve the overall structural bearing capacity and deformation resistance.

[0008] In the aforementioned drainage structure for a hardened road, the second drainage pipe has several through-holes on its wall. A second wire mesh is tightly wrapped around the outer wall of the second drainage pipe, with the mesh openings smaller than those of the drainage holes. This structure allows some water from the permeable concrete layer to enter the second drainage pipe through the wire mesh openings and drainage holes, accelerating water flow while reducing moisture in the permeable concrete layer. This allows the permeable concrete layer to better absorb surface moisture, accelerating drainage of the hardened road. The smaller mesh openings of the wire mesh prevent concrete and other impurities from clogging the drainage holes and pipe, ensuring drainage speed. Simultaneously, the tight wrapping of the wire mesh on the outer wall of the drainage pipe provides support, serving a dual function of preventing blockage and providing support. The wire mesh is secured to the outside of the drainage pipe using binding and clamps, ensuring it remains firmly attached and does not shift during construction.

[0009] In the aforementioned drainage structure for a hardened road, the second drainage pipe is installed at an angle downwards to both sides along the centerline of the hardened road, with the slope of the second drainage pipe between 1.5 and 3 degrees. This structure utilizes the principle of water flowing downhill to accelerate the drainage speed of the second drainage pipe, thereby speeding up the drainage of the hardened road. Furthermore, the slope of the second drainage pipe between 1.5 and 3 degrees ensures that the height difference between the two ends of the second drainage pipe is within a reasonable range, allowing the second drainage pipe to be installed entirely within the permeable concrete layer.

[0010] In the aforementioned drainage structure for a hardened road, the permeable concrete layer slopes to both sides of the centerline of the hardened road, with the slope ranging from 1.5° to 3°. This structure utilizes the principle of water flowing downhill, causing accumulated water to flow to both sides upon reaching the top surface of the permeable concrete layer, flowing towards the drainage well and accelerating the drainage speed of the hardened road.

[0011] In the drainage structure of the aforementioned hardened road, a seal is provided between the outlet end of the second drainage pipe and the permeable concrete layer. The seal prevents backflow of sediment, avoids blockage, and ensures drainage speed.

[0012] In the aforementioned drainage structure for a hardened road, the distance between the two first drainage pipes is 1 / 2 to 2 / 3 of the width of the hardened road. This structure, by rationally positioning the first drainage pipes, ensures that the water in the permeable concrete layer follows essentially the same path to the drainage well, thereby accelerating the drainage speed of the hardened road.

[0013] In the drainage structure of the aforementioned hardened road, the first drainage pipe and the second drainage pipe are sealed together by a tee joint. The tee joint is made of rigid polyvinyl chloride in one piece, which has good pressure resistance, corrosion resistance and sealing performance. The tee joint is fixed to the first drainage pipe and the second drainage pipe by adhesive bonding or hot-melt sleeve connection, and the interface is provided with a seepage-proof rubber ring or sealing gasket.

[0014] In the aforementioned drainage structure for a hardened road, both the first drainage pipe and the second drainage pipe are positioned adjacent to the base concrete layer. This structure allows water in the base concrete layer to flow more effectively to the first and second drainage pipes, thereby accelerating the drainage speed of the hardened road.

[0015] Compared with the prior art, the drainage structure for hardened roads provided by this utility model has the following advantages:

[0016] 1. This drainage structure includes a first drainage pipe and a second drainage pipe in the permeable concrete layer, ensuring that the water in the permeable concrete layer flows to the drainage well along the same path as possible. This allows water in the permeable concrete layer to flow to the drainage well through the first and second drainage pipes, enabling the permeable concrete layer to better absorb moisture from the ground, accelerating the drainage speed of the hardened road, and preventing efflorescence on the hardened road.

[0017] 2. The drainage structure has a first wire mesh tightly wrapped around the outer wall of the first drainage pipe and a second wire mesh tightly wrapped around the outer wall of the second drainage pipe. Both the first and second wire meshes serve the dual functions of preventing blockage and providing support, ensuring the smooth flow of the first and second drainage pipes, accelerating the drainage speed of the hardened road, and preventing the hardened road from experiencing efflorescence.

[0018] 3. This drainage structure is easy to construct, without the need for large-scale drainage ditches or complex layering. Rainwater can permeate into the permeable concrete layer on-site and be filtered through the wire mesh before being discharged into the drainage pipe, achieving rapid and organized drainage, reducing surface runoff, effectively preventing road water accumulation, improving traffic safety, and having low structural cost, making it suitable for large-scale promotion, especially for sidewalks, non-motorized vehicle lanes, and urban branch roads.
