Structure: The hose consists of an inner tube, reinforcement 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 exploitation and pour cast underground and underwater.
