It is formed and vulcanized in one time without overlap, which improves the airight performanceand safety factor; Water inflated or air inflated, can be used in freezing zone

Water flows through the bookend area, increasing the transverse tensile strength, reducing the rubber dam oscillation and impact of overflow water;

Good effect on collapse, water or air seldom remains in the dam when collapsing, the dam can be deflated completely, with less water retention in the downriver;

The bookend rubber dam was cut into grooves in the bookendarea in average distance forming up a beautiful waterful when the water overflows, which is good sight;

Short time installation, commonly apply single anchor system, saving the foundation construction and half the anchor plates, and need no bottom cushion sheet and level up cushion sheet;

Use the self—inflation/deflation system, control the height and air pressure of the rubber dam through the signal of the liquid level sensor and pressure sensor, high degree of automation, and can be easily managed;
