Water bladder for bridge pressure test
The bridge pre-pressed water bladder is made of high-strength polyester fiber coated with double-layer PVC film and is compounded at high temperature. It is resistant to low temperature
ultraviolet rays, and has a long service life. When the bladder is empty, it is easy to carry and easy
to operate. You only needs to place the empty water bladder on the pre-pressing part, and then
fill it with water . Due to the advantages of simple, accurate, low cost and reusable water bladder
testing, it will be an ideal choice for bridge preloading in the future.
At present, in the construction stage of a large number of highways and railways in domestic
and foreign, the preload test of bridge load is a key work in the inspection of engineering quality.
The general traditional method is to use iron cans or sandbags to pile up on the bridge to carry
out the actual pressure test. It takes a lot of manpower and material resources to transport these
large and load-bearing items from the low place to the bridge. and it is more time-consuming and
laborious on the site with poor construction. It can only be completed by using heavy lifting and
handling equipment, and there are certain labor safety hazards.The use of pvc soft foldable water
bladder for pre-pressing can solve those problems,It can save manpower and material resources.
It is safe and Reliable, It can reduce costs and shorten construction time.
Installation requirements and after-sales service
1. Before laying the bridge pre-pressurized water bag, it is necessary to inspect and clean the
