WATERPROOF UNDERGROUND POWER PIPE JOINING APPARATUS

摘要

PURPOSE: A waterproof underground power pipe joining apparatus is provided to seal a joint of a pipe and an adaptor linear portion to confirm waterproof for a power cable. CONSTITUTION: A waterproof underground power pipe joining apparatus couples a pipe(12) of a manhole with a synthetic resin ripple pipe(13) by using an adaptor(14). The apparatus comprises a sleeve packing(21), a packing protecting element(22), and a clamp(23). The sleeve packing(21) is made of soft elastic material and is coupled around an outer circumference of a joint of the pipe(12) and the adaptor(14) to insert both, simultaneously. The packing protecting element(22) is made of hard material and is coupled around the outer circumference of the sleeve packing(21). The clamp(23) is coupled around the outer circumference of the packing protecting element(22) and attached to the joint of the pipe(12) and the adaptor(14) with pressure.
