Method for injection of sealing grout e.g. thick mortar, into ground, involves injecting sealing grout into drilling tube after drilling tube reaches predetermined depth, where sealing grout is injected while vibrating drilling tube

摘要

The method involves providing a drilling tool including a drilling tube (12) having an open distal end (14), and a vibration generator (20) for vibrating the drilling tube. Drilling is carried out in the ground (S) with the drilling tool by vibrating the drilling tube, and the drilling tube is moved to a predetermined depth (H). A sealing grout is injected into the drilling tube after the drilling tube reaches the predetermined depth, where the sealing grout is injected into the drilling tube while vibrating the drilling tube.
