Polyethylene Road Barrier Segmentation Concrete Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road barriers lack a lightweight, durable, and easily transportable design that can be effectively filled with concrete at the installation site, while also providing stable connection and safety features for traffic control and construction purposes.
Innovation Solution
A road barrier constructed from a polyethylene body with longitudinal walls, embedded steel frames, and stabilizing bolts, featuring inlet openings for concrete filling, a wide frame for anchoring, and notched surfaces for vehicle speed reduction, allowing for easy assembly and connection with other segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional solid concrete barriers are used, then strength and stability are improved, but weight and transport difficulty increase
Solution Approach 1:
The barrier is divided into modular segments that can be transported separately and assembled at the destination. Each segment contains embedded steel frames that provide structural strength while the hollow interior reduces weight during transport. The segments are connected through coupling elements to form a complete barrier system.
Solution Approach 2:
Steel frames are embedded into the body during manufacturing before the barrier reaches its final destination. This preliminary action ensures structural strength is built-in from the start, eliminating the need for heavy solid concrete while maintaining barrier integrity during transport and assembly.
2Weight of moving object
If lightweight plastic bodies are used, then transport ease is improved, but structural strength and stability worsen
Solution Approach 1:
The barrier combines plastic (polyethylene or polypropylene) with embedded steel frames to create a composite structure. The plastic provides lightweight properties and corrosion resistance, while the steel frames provide structural strength and rigidity. This composite approach achieves both light weight and high strength simultaneously.
Solution Approach 2:
Steel frames are strategically embedded at critical locations within the plastic body to provide localized strength where needed most. The frames are positioned to reinforce the barrier at connection points and along the length where structural support is required, while the rest of the plastic body remains lightweight.
3Ease of operation
If modular segments with connection elements are used, then ease of assembly is improved, but device complexity increases
Solution Approach 1:
Connection elements are merged directly into the segment structure itself rather than being separate components. The coupling elements are integrated into the plastic body and steel frames, reducing the number of separate parts and simplifying assembly while maintaining ease of connection between segments.

AI summary
The road barrier is formed as uniform segment in the form of the hollow body formed of plastic, such as polyethylene, which is filled with concrete at the installation site. The road barrier is equipped with connecting elements for connecting with the other segment of the barrier and a stabilizing element with a base. The body of the road barrier is formed of polyethylene with longitudinal walls (2) with breakings which form a molding (3) in the upper part and has a frame in the lower part. The inner side of the body is reinforced with rods in the form of two longitudinal frames (8). The longitudinal frames are embedded in the inner ribs of the body.
