Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a road surface water seepage prevention structure and a road surface. Background Art

[0002] At present, groundwater erosion is the direct cause of road damage, and the irregularity of groundwater makes it impossible to stop its flow. The only way is to divert and isolate it to prevent it from eroding the road. Especially when it rains, there is sufficient groundwater and water seepage often occurs, which not only causes damage to the road surface, but also affects driving safety.

[0003] After searching, Chinese patent announcement number: CN219972841U discloses a road surface anti-seepage structure and a road surface, including the road surface anti-seepage structure, including a diversion layer, a diversion ditch, and an isolation plate; the diversion layer is laid on the roadbed, and the isolation plate is laid on the diversion layer, and the diversion layer is paved with pebbles or crushed stones; a diversion ditch is arranged in the diversion layer, the bottom of the diversion ditch is in contact with the roadbed, the top surface of the diversion ditch is closed, and the top surface and / or side surface of the diversion ditch are provided with a water inlet hole connected to the diversion layer, and the diversion ditch extends to both sides of the road surface and is respectively connected to the rainwater grates on both sides of the road surface.

[0004] The above technical solution is used to drain groundwater by setting up a diversion ditch, but the diversion ditch with a criss-cross structure is prone to cause groundwater to accumulate in the diversion ditch, and the drainage speed is poor. When the groundwater is sufficient, it is still easy to cause water seepage problems, and there is a lack of measures to drain the water on the road surface. In the case of heavy rain, water is easy to accumulate on the road surface, and the formation of water accumulation is easy to cause many inconveniences to pedestrians. At the same time, the accumulated water will also form a series of problems such as water film reflection, thereby affecting the driver's driving safety. Utility Model Content

When water accumulates on the road surface, rainwater seeps into the first drainage layer 3, and the rainwater in the first drainage layer 3 flows into the first drainage pipe 4, and then is discharged into the drainage ditch 2 through the first drainage pipe 4, forming a good drainage system to solve the problem of water accumulation on the road surface. The road surface and the roadbed are isolated by the set waterproof layer 5 to form an independent waterproof barrier, and the groundwater seeps into the second drainage layer 6 through the second drainage layer 6 and the second drainage pipe 7, and is quickly discharged into the drainage ditch 2 through the second drainage pipe 7. In this way, moisture can be prevented from penetrating from the roadbed into the road surface structure, thereby protecting the road surface from moisture erosion and damage and extending the service life of the road surface.

[0026] In this embodiment, if Figure 1 As shown, the first drainage layer 3 and the second drainage layer 6 are both formed by mixing crushed stone and gravel, and have a large porosity, allowing water to pass freely, while having a certain strength and stability.

[0027] In this embodiment, if Figure 2 and Figure 3As shown, the first drainage pipe 4 includes a plurality of main drainage pipes 401 distributed at equal intervals and a plurality of branch drainage pipes 402 fixedly connected between two adjacent main drainage pipes 401. The two ends of the main drainage pipe 401 are respectively communicated with the drainage ditches 2 on both sides. A plurality of drainage holes 4011 are evenly opened around the main drainage pipe 401 and the branch drainage pipe 402. The main drainage pipe 401 is arranged to be inclined downward toward the drainage ditch 2 along the center thereof. The angle between the two ends of the main drainage pipe 401 and the roadbed layer 8 is 5°-7°. The main drainage pipe 401 is designed as an inverted V-shaped structure. The branch drainage pipe 402 is arranged to be inclined toward the drainage ditch 2 along the center of the main drainage pipe 401. The angle between the water pipe 402 and the two connected main drain pipes 401 is 50°-65°. The design of the main drain pipe 401 and the branch drain pipe 402 increases the contact area with water, which helps to quickly drain the water. The main drain pipe 401 is designed as an inverted V-shaped structure, so that the main drain pipe 401 has a certain slope, so that after the water enters the main drain pipe 401, it can be quickly discharged into the drain ditch 2 along the slope. The branch drain pipe 402 and the main drain pipes 401 on both sides are also inclined, so that the water in the branch drain pipe 402 can quickly flow into the main drain pipe 401, thereby greatly improving the drainage speed and quickly solving the problem of water accumulation.

[0028] In this embodiment, the second drainage pipe 7 has the same structure as the first drainage pipe 4, so that groundwater enters the main drainage pipe 401 and the branch drainage pipe 402 of the second drainage pipe 7 and is quickly discharged into the drainage ditch 2, solving the problem of groundwater seepage.

[0029] In this embodiment, if Figure 3 As shown, a filter layer 4012 is arranged on the outside of the main drainage pipe 401 and the branch drainage pipe 402. The filter layer 4012 is made of a material with good filtering performance and a certain strength, such as geotextile, non-woven fabric, etc., which can form a dense filter layer to effectively intercept fine particles and impurities, prevent fine particles and impurities from entering the first drainage pipe 4 and the second drainage pipe 7 to cause blockage, and help to maintain the smooth and stable operation of the drainage system, thereby ensuring that the accumulated water on the road surface can be discharged quickly and effectively.

[0030] In this embodiment, if Figure 1As shown, the waterproof layer 5 is made of high-performance waterproof materials, such as modified asphalt, high molecular polymer, rubber asphalt, etc., which has good waterproof performance, weather resistance and durability, and can effectively prevent moisture penetration for a long time. A reinforced mesh cloth 501 is arranged inside the waterproof layer 5. The reinforced mesh cloth 501 can be made of glass fiber mesh cloth or polyester fiber mesh cloth, which can enhance the tensile strength and stability of the waterproof layer 5 to prevent it from cracking or breaking during use. Under the influence of vehicle load and temperature changes, the waterproof layer can remain flat and not crack, thereby maintaining its waterproof effect for a long time. It should be noted that the waterproof layer 5 needs to be laid on the roadbed according to the design requirements and be closely integrated with the pavement structure. During the laying process, it is necessary to ensure that the surface of the waterproof layer 5 is flat, free of bubbles and wrinkles, and is tightly connected to the adjacent parts to prevent moisture from penetrating from the joints.

[0031] In this embodiment, if Figure 1 As shown, a rain grate 201 is installed at the top of the drainage ditch 2. The rain grate 201 can prevent debris such as leaves, papers, and plastic bags from entering the drainage ditch 2 and causing blockage. In another embodiment, when paving the pavement layer 1, an angle of 2-4° with the ground can be maintained to allow road surface water to quickly flow into the drainage ditch 2 along the inclination, which helps to quickly drain the road surface water.

[0032] The present embodiment also provides a road surface, which applies the above-mentioned road surface anti-seepage structure, and also includes a steel mesh 101 arranged inside the road surface layer 1 and the road base layer 8, a plurality of first support columns 102 arranged at the bottom of the road surface layer 1, and a plurality of second support columns 801 arranged at the top of the road base layer 8. One end of the first support column 102 extends into the first drainage layer 3 and is placed in the space between the main drainage pipe 401 and the branch drainage pipe 402 of the first drainage pipe 4. One end of the second support column 801 extends into the second drainage layer 6 and is placed in the space between the main drainage pipe 401 and the branch drainage pipe 402 of the second drainage pipe 7. The structural strength of the overall road surface is improved by the steel mesh 101, the first support column 102 and the second support column 801.

[0033] The pavement anti-seepage structure and pavement of the present embodiment, through the arrangement of the first drainage layer 3 and the first drainage pipe 4, when water accumulates on the pavement, rainwater seeps into the first drainage layer 3, and rainwater in the first drainage layer 3 flows into the first drainage pipe 4. The design of multiple main drainage pipes 401 and branch drainage pipes 402 increases the contact area with water, which helps the water to quickly enter the first drainage pipe 4. The main drainage pipe 401 is designed as an inverted V-shaped structure, so that the main drainage pipe 401 has a certain slope, so that after the water enters the main drainage pipe 401, it can be quickly discharged into the drainage ditch 2 along the slope. The branch drainage pipe 402 and the main drainage pipes 401 on both sides are also inclined, so that the water in the branch drainage pipe 402 can quickly flow into the main drainage pipe 401, thereby greatly Improve the drainage speed and quickly solve the problem of water accumulation. Through the second drainage layer 6 and the second drainage pipe 7, groundwater can penetrate into the second drainage layer 6 and be quickly discharged into the drainage ditch 2 through the second drainage pipe 7. This can prevent moisture from penetrating from the roadbed to the pavement structure. A filter layer 4012 is arranged on the outside of the main drainage pipe 401 and the branch drainage pipe 402 to form a dense filter layer, which can effectively intercept fine particles and impurities and prevent fine particles and impurities from entering the first drainage pipe 4 to cause blockage, which helps to keep the drainage system unobstructed and stable. Through the waterproof layer 5, an independent waterproof barrier is formed, which can prevent moisture from penetrating from the roadbed to the pavement structure, thereby protecting the pavement from water erosion and damage and extending the service life of the pavement.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
