[0002] With the development of traffic construction in China, the construction of municipal highways and expressways, the demand for central isolation strips is also increasing. Central isolation strip is an important road facility, which can prevent vehicles from turning around in non-designated areas, block the light of oncoming vehicles, guide the driver's vision, relieve visual fatigue, reduce noise and improve air quality, and significantly improve the safety of the road and the comfort of driving. At the same time, the central isolation strip can also beautify the road environment and reduce the impact of exhaust emissions on the surrounding environment, thereby ensuring smooth traffic and improving the overall environmental quality of the road.

[0003] Currently, there are some problems with the central isolation strips installed on highways. Although these metal barriers are light, low cost and easy to install, they have obvious limitations in actual use. First of all, they cannot effectively block the light of oncoming vehicles, and the protection of the driver's vision is insufficient. Secondly, these barriers have poor anti-collision and anti-impact performance, which greatly reduces their practicality. In addition, the existing central isolation strips also have challenges in construction and maintenance, such as poor impact resistance, complex construction, poor greening effect, and high difficulty and safety hazards in maintenance on expressways.

[0004] Therefore, there is an urgent need for a central isolation strip that is simple in structure, easy to install and maintain, has good anti-light effect, good impact resistance, and greening function. INVENTION CONTENTS

[0023] Various exemplary embodiments of the present invention are now described in detail. This detailed description should not be considered as a limitation of the present invention, but should be understood as a more detailed description of certain aspects, features and implementations of the present invention.

[0024] Various improvements and variations can be made to the specific embodiments described in this utility model without departing from the scope or spirit of this utility model, which will be obvious to those skilled in the art. Other embodiments derived from this utility model description will also be obvious to those skilled in the art. This application specification and embodiments are merely exemplary.

[0025] This utility model provides a quick-assembly U-shaped central median strip, such as Figures 1-4 The diagram shows the structure of the central median strip. In a specific embodiment, the central median strip includes a U-shaped median strip 1, with the front and rear ends of the U-shaped median strip 1 serving as connecting ends. One end of the U-shaped median strip 1 is provided with a tenon structure 2, and the other end is provided with a mortise and tenon structure 3. Adjacent U-shaped median strips 1 are connected by inserting the tenon structure 2 and the mortise and tenon structure 3. In this embodiment, the end with the tenon structure 2 is the front end, and the end with the mortise and tenon structure 3 is the rear end.

[0026] The U-shaped isolation strip 1 has a U-shaped groove in the middle. The bottom of the U-shaped groove and the two side walls are provided with chamfered slopes 5 to prevent rainwater from accumulating at the corners and corroding the central isolation strip.

[0027] At the bottom of the U-shaped channel, between the two chamfered slopes 5, there is a planting trough 4 for planting vegetation to beautify the road environment.

[0028] Furthermore, along the connecting direction of the U-shaped isolation strip 1, the top of the front and rear side walls of the planting trough 4 extends from the center line towards the chamfered slopes 5 on both sides to form the bottom plate slope 6. The height of the bottom plate slope 6 near the center line is higher than the height of the chamfered slope 5 at its connecting position.

[0029] Furthermore, the chamfered slope 5 and the base plate slope 6 form an angled channel, which serves as a water-guiding channel 7. The water-guiding channel 7 is used for central drainage of the U-shaped central isolation zone 1, facilitating future maintenance of the central isolation zone. During rainfall, rainwater is collected at the opening of the U-shaped trough and flows towards the planting trough 4, irrigating the vegetation. When the planting trough 4 is full of rainwater, excess rainwater is discharged through the water-guiding channel 7, preventing rainwater from accumulating inside the U-shaped trough.

[0030] In a specific embodiment of this utility model, at least three tenon structures 2 are provided at the end of the U-shaped isolation strip 1, respectively located at the bottom of the front end of the U-shaped isolation strip 1 and on both side walls.

[0031] Furthermore, the tenon structure 2 has a chamfer 8 at its end. The chamfering at the end of the tenon structure 2 reduces friction at the interface of the central divider during assembly, improving the overall assembly efficiency. In this embodiment, the tenon structure 2 is a cylindrical concrete tenon.

[0032] In a specific embodiment of this utility model, at least one planting trough 4 is provided in the U-shaped groove of each U-shaped isolation strip 1. In this embodiment, two planting troughs 4 are provided in the U-shaped groove along the connection direction of the U-shaped isolation strip 1.

[0033] The installation process of the central median strip provided by this utility model is as follows:

[0034] Step 1: Prepare multiple U-shaped isolation strips, place them horizontally, and connect the tenon structure 2 and the mortise and tenon structure 3 on the multiple U-shaped central isolation strips 1 in sequence to form a complete central isolation strip.

[0035] Step 2: Plant vegetation in the planting trough 4 inside the assembled central median strip. This completes the assembly and planting of the central median strip.

[0036] When rain occurs during use, the U-shaped central median strip collects rainwater through the top opening to irrigate the vegetation in the planting trough 4, and also prevents soil from flowing onto the road surface on both sides of the median strip.

[0037] When there is excess rainwater or heavy rainfall, the rainwater can be drained through the water channel 7 formed by the chamfered slope 5 on the inner side of the U-shaped channel and the slope 6 on the bottom plate, thus preventing rainwater from accumulating.

[0038] The above description is merely an illustrative embodiment of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model shall fall within the scope of protection of this utility model.
