Rubber dam

Rubber dam Rubber dam is a new type hydraulic structure. It is made of sized high strengh fabric adhering rubber , which forms he rubber bag anchoring to he foundation. After full-filled wih water or air, it can be used for water retention. Rubber dam has many advantages, such as he rubber dam project only cost 1/3-2/3 of he conventional dam, short construction time, low running cost, he investment can be take back in he same year which is highly appreciated by little hydraulic power station. Besides, he rubber dam have lighter self-weight, and he collapsing dam do not obstruct water, good oscillation absorption performance etc. As he developing of multiple market tendencies and rubber technology, a new more advanced rubber dam type-bookend rubber dam, appears on he world market. Our company begins to design and produce he bookend rubber dam from 2005, and its advantages are as follows: Bookend rubber dam is formed and vulcanized at factory in one time; it has solved he airtight performance of he conventional overlap rubber dam, and improved he safety factor and its life span He bookend rubber dam seems like a book, and he bookend area are disposed .In his way, it solved he problems during he conventional air filled rubber dam running, increased he transverse tensile strengh, reduced he rubber dam oscillation and he impacted of overflow water.
