Product Description:

In the construction of railway and highway bridges, preloading testing is an important link to ensure the safety of bridge structures. The traditional method of preloading sandbags has problems such as difficulty in handling, cumbersome operation, and high cost.

Our Pre pressure flexible tank is processed by condensation force, with super strong anti swelling strength. After being filled with water, it can provide sufficient weight, perfectly replacing traditional sandbag preloading and becoming an ideal choice for modern bridge construction.

Features:

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

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

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

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

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

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

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

8. 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, and water bags can be filled with water to use, resulting in higher efficiency.

2. Cost: Sandbags are disposable and have a high cost; The water bag can be reused, making it more cost-effective in the long run.

3. Environmental friendliness: Sandbags are prone to generating waste, while water bags are environmentally friendly and reusable.

4. Safety: The water bag has high anti swelling strength, is not easy to break, and is safer to construct.

Applications:

Railway bridge construction: This method is utilized for conducting bridge preloading testing in order to guarantee the structural stability of the bridges.

Highway and bridge construction: Instead of sandbags, our solution offers effective and cost-efficient preloading options for various construction projects involving highways and bridges.

For other large-scale construction endeavors, like elevated bridges and overpasses, this approach can be effectively utilized to ensure the stability and integrity of the structures.
