Bridge Preloading Test Pressurized Water Bladder Used For
PVC bridge preloading water bag (also called bridge preloading
water bladder) is a kind of soft and foldable container.
FL PVC preloading water bag is made of high strength PVC
composites.The products have advantages of certain tensile
strength,elasticity and air tighthness.After injecting water,it can
instead original sandbag and could be used many times,is a kind of
package product which could reduce cost and speed up construction
progress.The bridge preloading water bag could change the damage of
labor because of traditional sandbag preloading,also could save the
sand from repeated using.The outstanding advantage is improving the
speed of construction period,and ensure the process of the project
Advantages of FL pressurized water bladder
1. The method is simple and the labor intensity is low
2. Water bag can be used repeatedly with low cost.
3. The water from bag can be used repeatedly,more environmental
4. The lowest time is to use 3 hours to instal,with high efficiency
5. The preloading water bags are fully furnished,with preloading
water bag,water pump,turnaround water bag and so on.
6. For the same one project,we can provide several set of same
water bag,which could realize continue preloading and use water
7. Meanwhile,we also prepare turnaround water bag,used for storage

Instruction of FL bridge preloading water bladder
1. Paving water bag
Spread the water bag to the desired platform, pay attention to the
platform can not have sharp things, so as not to damage the water
If the height of water bag is more than 2m,the workers must use
sandbag(or other way such as scaffold) to reinforce around water
bag according to its size,in order to reduce pressure on water bag
side and avoid the water bag bursting and rolling.
3. Inject water
Close the drain valve,connect water pipes to inlet valve on both
ends,and then use submersible pumps to pump and inject water.Note
that the pipe joints can not leak, so as not to leak into the
already processed foundation.
Inject water until reach the required height and preloading until
the required time.
5. Drain the water
When finish preloading,connect water pipes to drain valve and drain
the water.In order to use water repeatedly,the workers also could
connect vacuum pump to inlet valve and inject the water into other
6. Move and store
After folding the water bag without water,use harness to fasten and
then move away from ground.Put the foladable water bag into room
and avoid sun exposure in order to extended service life.
When using the water bag,workers should prevent nails or other
sharp hard objects to damage the bag.If have damage,use wheel or a
wooden file to polish the bag,brushing glue and cover tape to
repair(it had better use recommended glue from factory),and then
place bag for appropriate time and use it again.
