Water inflatable rubber dam is a kind of water-inflated stable tear-shaped rubber dam. Rubber dam consists of civil works, dam bag, anchor, filling drainage facilities and control system. It is made of strength canvas as reinforced framework and rubber layer which ensure tightness of the rubber layers. Compared with air inflatable rubber dam, water inflatable rubber dam is more expensive and slower to fill but more stable to provide optimal control over upstream water levels. It is fixed to concrete to create a permanent dam or floodgate. Water can spill over the top automatically without additional support or adjustment. When the flood is coming, rubber weir can completely collapse, does not have water resistance. It is usually used to retain water, adjust the water level, irrigation, generate hydro-electric power, control flood, etc.

Feature
It is more expensive, slower to fill, but more stable to control over upstream water level than air inflatable rubber dam.
Tear-shaped rubber dam is on the wide concrete still.
It can withstand overflow 50% in height.
It can operate without electric power.
Outer rubber is thick, is resistant to wear, sunlight, heat, ozone, aging, etc.
Middle layer rubber can protect canvas and connect canvas.
Inner rubber has high airtight and watertight, is resistant to aging of canvas.
Inflating and deflating time of water inflatable rubber dam is longer than air inflatable rubber dam.
Inflating water stably, dam bag is heavy which can decrease vibration.
Water inflatable rubber dam is high volume low pressure system, so high pressure compressors are not needed.
Compared with conventional sluice dam, investment of water inflatable rubber dam reduced by 30-70%, wood saved by over 60%, steel saved by 30-50%, concrete saved by 50%.
Bookend rubber dam, also named as spine type rubber dam, has obvious fins on the dam body to form a rising angle when the dam is inflated. It is made of high strength canvas as the reinforced framework and synthetic rubber fixed to a reinforced concrete foundation using clamping plates and anchor bolts. In dry seasons, the rubber dam is inflated by air or water to retain water for industrial, agricultural and living water demands; in rainy seasons, the air or water in the sealed bag can be deflated out to release floodwater from river course. Bookend rubber dam heightens overflow's water head and eliminates vacuum underneath the dam to reduce the vibration and abrasion. It is usually used to retain water, agricultural irrigation, generate electricity, control flood, beautify environment, etc. Specification Material structure: one cloth two rubber, two clothes three rubber, three clothes four rubber, etc. Color: blue, black, red, gray, purple, etc. Medium in dam: air or water. According to installation method: Single anchor. Double anchor (pillow-like dam and inclined dam). According to anchored method: Bolt anchored. Wedge anchored. Customization can be available. Feature It can be resistant to vibration, abrasion, dirt, sediment, sedimentation, sunlight, heat, ozone. It has smooth surface with spines, can eliminate vacuum underneath the dam, can create a beautiful scene of waterfall. Automatic inflation and deflation system provides the dam excellent control of height and air pressure. Vulcanization molding one time, increase the lateral tension of dam bag.

Rubber dam is a new type of hydraulic structure compared with steel sluice gate, and made of high-strength fabric adhering with rubber, which forms a rubber bag anchoring on basement floor of dam. Filling water or air into the dam bag, rubber dam is used for water retention. Emptying water or air from the dam bag, it is used for flood release. Rubber dam has many advantages compared to conventional weirs, such as low cost, simple hydraulic structure, short construction time, perfect seismic performance and effect of stopping leading, and low resistance to water flow in flood season.
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.
