In the construction of railway and highway bridges, preloading testing plays a crucial role in ensuring the safety of bridge structures. The conventional approach of using sandbags for preloading presents challenges like handling complexity, laborious operation, and high expenses. On the other hand, our Pre pressure flexible tank is manufactured using compression forces, resulting in exceptionally high anti-swelling properties. When filled with water, it can offer substantial weight, effectively substituting the traditional sandbag preloading method. This makes it an excellent option for modern bridge construction projects.
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.
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.
Railway bridge construction involves the utilization of bridge preloading testing to guarantee the structural stability of the bridge.
In highway and bridge construction projects, sandbags can be substituted with efficient and cost-effective preloading solutions.
For other large-scale construction ventures like elevated bridges and overpasses, similar techniques can also be applied.
