METHOD OF BUILDING UNDERGROUND CONTINUOUS WALL PREVENTED FROM LEAK OF WATER

摘要

PURPOSE:To build a solid underground continuous wall, by a method wherein, after reinforcing bars are arranged in a trench and the trench is filled with concrete, grout is pressed in the concrete through the grout press-in pipes of a vertical joint erected in the trench. CONSTITUTION:After an interlocking pipe 9 and a guide plate 10 are erected in the following panel section side in a trench 8, a vertical joint 1 is erected in the trench 8, and a reinforcing bar cage 7 is erected in a manner that it is superposed with oblique reinforcing bars 3 of the joint 1. Concrete is placed in a portion on the reinforcing bar cage 7 side, partitioned by a partitioning plate 2 of the joint 1 in the trench 8. Grout is pressed in a pipe 6 with holes of a cut-off member 4 from above, and is caused to enter a portion, where filling with concrete is incomplete, through holes 6a to build a panel. Further, a after the pipe 9 and the guide plate 10 are erected in the trench 8 excavated in a following panel section, the similar procedures as described above are orderly followed to build a panel.
