Product Description:

In the process of building railway and highway bridges, conducting preloading tests is a crucial step to guarantee the safety of the bridge structures. The traditional approach of using sandbags for preloading poses challenges like handling difficulty, complex operation, and high expenses. Our innovative Pre pressure flexible tank is crafted with superior condensation force, featuring exceptional anti-swelling capabilities. Once filled with water, it offers ample weight, effectively replacing conventional sandbag preloading and emerging as a preferred option for contemporary bridge construction.

Features:

Easy to transport: When the bag is empty, it is lightweight and easy to transport and handle, greatly reducing labor costs.

Easy to operate: Simply inject water to use, no need for complex equipment or technology, saving time and manpower.

Time and effort saving: Rapid water injection and drainage significantly improve construction efficiency and shorten the construction period.

Accurate testing: evenly distribute weight to ensure accurate and reliable preloading test data.

Low cost: Reusable, reducing material waste, and more economical for long-term use.

Reusable: High strength PVC material has strong durability and can be used multiple times, suitable for long-term project needs.

Safe and reliable: High tensile strength, not easily broken, ensuring construction safety.

Environmental innovation: replacing traditional sandbags, reducing environmental pollution, and in line with modern environmental construction concepts.

Comparison with traditional sandbag preloading:

1. Efficiency: Traditional sandbag handling is time-consuming and labor-intensive, while water bags can be filled with water for use, resulting in higher efficiency.

2. Cost: Sandbags are disposable and expensive; on the other hand, water bags can be reused, making them more cost-effective in the long term.

3. Environmental friendliness: Sandbags tend to create waste, whereas water bags are environmentally friendly and reusable.

4. Safety: Water bags have high resistance to swelling, are less likely to break, and provide a safer construction option.

Applications:

• Railway bridge construction involves the utilization of bridge preloading testing to verify the structural stability of the bridge.
• In highway and bridge construction projects, sandbags can be replaced with efficient and cost-effective preloading solutions.
• Various large-scale construction projects, including elevated bridges and overpasses, can also benefit from these innovative methods.
