Rubber water poured sealing appliances
CONSTRUCTION:The hoseconsists of an inner tube,rein-forcement layer,middle layer and rubber cover.
Feature:The hose body length decreased,the diameter increase and on the expansion state after hose enduring internal upright pressure.
Under this conditions,the hose accomplishes the hole sealing function
APPLICATION: a.Apply to coal mine and clear dust.
b.Apply to engineering construction and leak prevention construction underground.
c.Apply to tunnel exploitaton and pour cast underground and underwater.
