Reuse And High Quality Of Bridge Preloading Water Bladder Used For Pressure Test
PVC bridge preloading water bag (also called bridge preloading water bladder)is a kind of soft and foldable container.
ARD 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 ARD bridge preloading 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 bag could be used as storage water bladder for other water request on site
4. Can be overlapping two bags, to meet the tonnage of the bridge preload
5. The lowest time is to use 3 hours to install, with high efficiency
6. For the same one project,we can provide several set of same water bag,which could realize continue preloading and use water repeatedly.
7. Meanwhile,we also prepare turnaround water bag,used for storage testing water.
Featuers and various colors of PVC and TPU material
2. Temperature Resistance:-30-70℃
3. Tear Resistance:W:100.3-200N/cm; F:80.16-190N/cm
4. Adhesion: W:3.6-46N/cm; F:35.28-47N/cm
5. Color: red,blue,black,yellow,orange,white...
Instruction of ARD 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 bag
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 water bag.
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.
