Description

Technical Field

[0001] This utility model belongs to the field of road engineering technology, specifically a high-strength highway pavement drainage structure. Background Technology

[0002] Common road surface drainage systems are divided into two types: diffused drainage and centralized drainage. Diffuse drainage involves allowing surface water to flow laterally across the embankment slope. Centralized drainage uses retaining walls to divert water away from the roadbed through slope chutes. For road sections with high fill heights and unprotected slopes, or in areas where rainfall is heavy despite slope protection, centralized drainage systems are used to remove surface water and prevent it from impacting roadbed safety and stability. Centralized drainage systems also quickly remove water from the road surface and shoulders, preventing water accumulation and ensuring safe driving.

[0003] Moreover, when rainfall is heavy and there are many lanes, the amount of water collected on the road surface is large. If water barriers are installed, the water on the road surface will collect in the cross section of the water barrier and form water accumulation. When the water accumulation is large, the water in the cross section will overflow the shoulder and invade the cross section of the driving lane, thus affecting the smoothness and safety of traffic. Therefore, we propose a high-strength highway pavement drainage structure. Utility Model Content

[0004] To address the problems in existing technologies where road drainage spreads to pedestrian crossings, causing vehicles and pedestrians to slip or fall, and increasing transportation and maintenance costs, this utility model provides a high-strength highway pavement drainage structure. Through the combination of high-strength precast concrete water-blocking ditches and rapid flow channels, water from pedestrian crossings and the road surface is collected inside the drainage ditch, reducing the risk of vehicles and pedestrians slipping or falling and improving safety.

[0005] To achieve the above objectives, the specific technical solution is as follows: A high-strength highway pavement drainage structure includes a roadbed centerline, which is located in the middle of the pavement. The position of the roadbed centerline is determined according to the width of the pavement and varies with the width of the pavement. A driving lane is provided on the right side of the roadbed centerline for vehicles or pedestrians. An inner edge of an earthen shoulder is provided on the right side of the driving lane. A high-strength concrete precast water-retaining ditch is provided on the right side of the inner edge of the earthen shoulder for collecting rainwater. Several sets of rapid flow channels are provided on the right side of the high-strength concrete precast water-retaining ditch.

[0006] Furthermore, the right side of the high-strength concrete precast water-blocking ditch is provided with an outer edge of the roadbed, and the outer edge of the roadbed is connected to the left side of the rapid flow channel.

[0007] Furthermore, a roadbed slope is provided on the right side near the outer edge of the roadbed, and the roadbed slope is connected to the rapid flow channel.

[0008] Furthermore, a slope protection channel is provided on the right side of the rapid flow channel, and the slope protection channel is connected to the rapid flow channel.

[0009] Furthermore, a drainage ditch is provided on the right side of the slope protection road.

[0010] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0011] 1) By setting up high-strength concrete precast water-blocking ditches, rapid flow channels, and drainage ditches, the center line of the road is determined according to the road surface condition. Then, high-strength concrete precast water-blocking ditches are set up on both sides of the center line. The bottom of the high-strength concrete precast water-blocking ditches is filled with precast concrete to make the bottom of the high-strength concrete precast water-blocking ditches flat. Then, the bottom of the high-strength concrete precast water-blocking ditches is connected to the rapid flow channels, and the bottom of the rapid flow channels is connected to the drainage ditches. Through the above design, water on the road surface can be prevented from spreading to the pedestrian crossing. At the same time, the design structure is simple, easy to transport and maintain, and reduces construction costs. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0017] like Figures 1-3 As shown, this utility model aims to provide a high-strength road drainage structure to solve the problems of water stain spread on pedestrian crossings and the difficulties in transporting and maintaining drainage structures on both sides of the road in the prior art. Based on the above functions, the entire device includes a high-strength precast concrete water-blocking ditch 5, a rapid flow channel 7, and a drainage ditch 9.

[0018] like Figure 3 As shown, this structure is a high-strength precast concrete water-blocking ditch. Compared with traditional asphalt concrete water-blocking strips, it has the advantages of being lightweight, simple in structure, easy to transport, construct, maintain and repair, flexible in size, and safer.

[0019] like Figure 2 As shown, this utility model includes a roadbed centerline 1, which is located in the middle of the road surface. The position of the roadbed centerline 1 is determined according to the width of the road surface and changes according to the width of the road surface. A driving lane 2 is provided on the right side of the roadbed centerline 1 for vehicles or pedestrians. An inner edge 3 of an earthen shoulder is provided on the right side of the driving lane 2. A high-strength concrete precast water-blocking ditch 5 is provided on the right side of the inner edge 3 of the earthen shoulder. The high-strength concrete precast water-blocking ditch 5 is used to collect rainwater. Several sets of rapid flow channels 7 are provided on the right side of the high-strength concrete precast water-blocking ditch 5. An outer edge 4 of the roadbed is provided on the right side of the high-strength concrete precast water-blocking ditch 5. The outer edge 4 of the roadbed is connected to the left side of the rapid flow channels 7. A roadbed slope 6 is provided on the right side of the outer edge 4 of the roadbed. The roadbed slope 6 is connected to the rapid flow channels 7. A slope protection road 8 is provided on the right side of the rapid flow channels 7. The slope protection road 8 is connected to the rapid flow channels 7. A drainage ditch 9 is provided on the right side of the slope protection road 8.

[0020] Specifically, the high-strength concrete precast water-retaining ditch 5 is designed as a high-strength concrete precast structure. Its dimensions can be prefabricated in the factory according to the road surface water catchment volume to ensure its quality and appearance. Next, after the road surface construction is completed, the construction area is cleaned, including removing debris. Then, according to the design drawings, the centerline and edge lines of the high-strength concrete precast water-retaining ditch 5 are marked on the side of the roadbed, and the accuracy of the marking is checked to ensure that the dimensions meet the requirements. The bottom of the high-strength concrete precast water-retaining ditch 5 is compacted and leveled to ensure foundation stability. Then, when laying the precast blocks, a layer of composite geomembrane is laid at the bottom. The main function of this design is to prevent rainwater infiltration from affecting the stability of the roadbed. Finally, a layer of... Cement mortar is used to smoothly lay the precast blocks on top of the cement mortar. During splicing and installation, the joints of the precast blocks must be tightly connected. Special sealing materials or cement sand are used to seal the joints to prevent rainwater leakage. After the high-strength concrete precast water-blocking ditch 5 is installed, a slope rapid flow channel 7 is set every 30-50m at the slope. The slope rapid flow channel 7 is mainly made of concrete. The slope rapid flow channel 7 connects the high-strength concrete precast water-blocking ditch 5 to the slope toe drainage ditch 9, ensuring that the water flow in the high-strength concrete precast water-blocking ditch 5 flows into the slope toe drainage ditch 9, preventing road surface water from eroding the slope and causing water stains on the pedestrian crossing, which would affect the safety of pedestrians and vehicles.
