Abstract
The utility model discloses a latch-type underground pipeline protector. The latch-type underground pipeline protector comprises a semi-circular double-rack protective clack and a semi-circular wide-rack protective clack which are hinged through a fixing shaft pin. The semi-circular inner wall of the semi-circular double-rack protective clack and the semi-circular inner wall of the semi-circular wide-rack protective clack are respectively provided with a semi-circular rubber barrel. The inner walls of the two semi-circular rubber barrels are respectively provided with an axial semi-circular groove used for placement of a pipeline. After the semi-circular double-rack protective clack and the semi-circular wide-rack protective clack are buckled, a locking device is arranged at the other end opposite to the fixing shaft pin. Due to the fact that a matched hydraulic installing tool rights and tightly presses the latch-type underground pipeline protector, the protection intensity and the protection effect of the underground pipelines are enhanced, and meanwhile the labor intensity is lowered.
