Spoiler Rubber Dam - Anti Vibration Effectively

Spoiler rubber dam, also known as disturbed flow rubber dam, adds the spoiler seismic structure at the base of common rubber dam. It is made of rubber cloth vulcanized by EPDM and synthetic fabrics. Rubber dam can be inflated by air or water. It can effectively prevent rubber dam oscillating or squirming, thereby reduce the friction with downstream rubber protective layer result from rubber dam vibration. It is usually used to retain water, control flood, agricultural irrigation, power generation, beautify environment, etc.

A black spoiler rubber dam is on the side of the river.
SRD-1: Spoiler rubber dam has good elasticity.
Spoilers on a piece of black spoiler rubber dam bag.
SRD-2: Spoiler on the rubber dam can reduce the vibration of the dam bag.
A blue spoiler rubber dam is in the river which water level is low.
SRD-3: Spoiler rubber dam has good tensile strength.
The water overflows the spoiler rubber dam and forms a waterfall.
SRD-4: Spoiler rubber dam can be resistant to weathering.

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
