1. Project Background: Why Do Large Airports Require High Settlement Compensation?
In large-scale infrastructure projects such as Shanghai Pudong International Airport, pipeline systems must cope with complex foundation settlement issues. Over time, uneven settlement can create significant stress at pipe connection points.
In this project, the client required a solution capable of handling 300mm settlement, which presents a major technical challenge for conventional rubber expansion joints.
2. What Is a WCR-L Type Anti-Settlement Wound Rubber Expansion Joint?
The WCR-L type anti-settlement wound rubber expansion joint is specifically designed for large displacement and high-settlement conditions. It adopts a multi-layer winding structure combining high-strength fabric reinforcement and rubber materials.
Compared to standard rubber joints, it offers superior tensile strength, compression resistance, and fatigue durability, making it ideal for airports, municipal systems, and large infrastructure projects.
3. How to Achieve 300mm Settlement Compensation? Key Technical Insights
Achieving 300mm settlement is not simply about increasing product length—it requires a comprehensive engineering design:
Multi-layer winding reinforcement to enhance tensile strength
Optimized rubber formulation for improved elasticity and durability
Special corrugated structure design for large displacement absorption
Reinforced flange connections to ensure stability during movement
These features ensure long-term reliability even under extreme settlement conditions.
4. What Are the Advantages of Wound Rubber Expansion Joints?
Compared to traditional molded rubber joints, wound-type expansion joints offer several key benefits:
Customizable for large displacement (e.g., 300mm settlement)
Higher pressure resistance and fatigue performance
Better adaptability to complex installation environments
Longer service life with reduced maintenance costs
They are increasingly becoming the preferred solution in large engineering projects.
5. Why Do Large Projects Prefer Customized Expansion Joints?
Standard products often cannot meet unique project requirements. Customized expansion joints can be tailored based on:
Pipe size and specifications
Working pressure
Temperature conditions
Required displacement compensation
This ensures optimal performance and long-term system safety.
