Japanese Patent JP2022154105
Kind Code:
A
Abstract:
To provide a connection jig for a fixing material injection hose capable of quickly, easily and surely connecting injection pipes to each other, relating to the connection jig for the fixing material injection hose in anchor work or rock bolt work.SOLUTION: The present invention comprises an injection pipe section 1, a guide pipe section 2 and an external pipe section 3 with a thread. A threaded section 4 inside the external pipe section 3 prevents a connecting hose from coming off even when injection pressure is applied due to frictional resistance. The guide pipe section 2 is made larger than the outer diameter of the connecting hose, so that it can be easily connected to the connecting hose even if the connecting hose is deformed or bent. A pair of upper and lower pedestals provided on the external pipe section is provided, the upper pedestal 5a is made larger than the lower pedestal 5b, a pedestal tightening bolt 6 is slightly loosened, and the connecting hose is easily attached and detached by pushing up the upper pedestal 5a with a finger.SELECTED DRAWING: Figure 1
