APPARATUS FOR STEADY INJECTING OF GROUT MATERIAL IN GROUND ANCHOR AND STEADY INJECTING METHOD OF GROUT MATERIAL USING SUCH APPARATUS

摘要

PURPOSE: A continuous grout injection device of an anchor and a grout injection method of an anchor using the same are provided to reduce the construction time of an anchor by continuously injecting grout into anchor holes with uniform pressure. CONSTITUTION: A continuous grout injection device(1) of an anchor comprises a chamber(10) and a pocket member(20). The chamber has a sealed space. The pocket member is arranged inside the chamber. When grout is supplied from a grout mixer to the pocket member through an injection pipe(200) and an outer supply pipe(30), the pocket member is inflated. When the supply of the grout is stopped, the pocket member is contracted by the inner pressure of the chamber, and the grout filled in the pocket member is discharged to anchor holes through the outer supply pipe and the injection pipe.
