Spoiler rubber dam consists of rubber bladder, anchoring clamping system, air evacuation system, anti vibration and anti vibration spoiler, abrasion resistant protective layer. Following I will introduce the five parts in detail.
Rubber bladder
Spoiler rubber dam is made of 90% EPDM. EPDM is a kind of special rubber with notable features in extreme temperatures, also can be resistant to weathering, ozone, UV. Spoiler rubber dam uses high strength polyester fabric which makes the dam bag have high tensile strength, obvious revivification advantage, not deform in long term using.
Anchoring clamping system
Anchoring clamping system is simple, easy to install, and a airtight waterproof system. According to different upstream water level and other factors, single anchor or double anchors can be used to fix rubber dam foundation. Clamping plates and anchor bolts usually are fixed on concrete foundation, also can be fixed on existing hole, then pour resin.
Air evacuation system
When air inflatable rubber dam complete collapse, dam bag is flat and no resistant to water. An independent air evacuation system channel evacuates air to exhaust vent ensuring that no remain air form, thereby guaranteeing dam bag cave in completely.
Anti vibration and anti vibration spoiler
Multivariate river flow and velocity of flow make whole or part dam bag vibrate which is solved by spoiler. Water overflow curtain passed spoiler can balance pressure which is the main control system of rubber dam seismic function.
Abrasion resistant protective layer
Protective layer can provide the rubber dam a complete protection, not only can prevent downstream abrasion, but also can prevent debris resident in the dam downstream.
Specification
