EARTHQUAKE RESISTANT SLEEVE FOR PIPE CONNECTED TO MANHOLE

摘要

PROBLEM TO BE SOLVED: To provide an earthquake resistant sleeve for a pipe connected to a manhole, allowing the earthquake resistant sleeve to be easily and efficiently fitted in the watertight state to the pipe already connected to the manhole, from the inside of the manhole without digging up the soil around. SOLUTION: In an earthquake resistant sleeve for a pipe 1 connected to a manhole 2, the outer periphery of a tubular joint rubber 3 provided at one end with a fitting collar 4 to a manhole internal wall is bonded through an adhesive to the inner surface of the pipe 1 connected to a manhole fixed to the manhole 2, and the fitting collar 4 is connected to a manhole fixed to the manhole internal wall.
