GROUT INJECTION IMPLEMENT AND GROUT INJECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a grout injection implement and a grout injection method for reducing time required to inject grout into a duct and injecting grout completely into the duct and into both cylinder parts of an anchor implement. SOLUTION: This grout injection implement 20 is mounted to the anchor implement 3 anchoring the end part of a prestressed concrete steel 19 inserted through a duct 2 passing through a segment constituting a shield tunnel lining body, to inject grout into the duct 2. The anchor implement 3 has a pair of cylinder parts 5 integrally formed to intersect each other. The grout injection implement 20 is provided with a pair of cylindrical grout injection implement bodies 21 respectively fixed to the other end parts 4b of the respective cylinder parts 4 of the anchor implement 3, and a hose joint 25 detachably provided at the grout injection implement body 21 to connect the grout injection implement body 21 to the hose 23 into which the grout is injected.
