摘要： PROBLEM TO BE SOLVED: To prevent a core member from moving and let it remain at a predetermined position even if concrete is placed after constructing the core member in a digged channel and prevent the occurrence of a clearance in mud soil mortar such as placed concrete. SOLUTION: The digged channel 1 is formed, a spacer 21 is attached to a bottom part of the core member 3 of H steel, and an interval between the core members is held to construct the core member in the digged channel. A pouring pipe 43 is arranged between the core members 3. Since mud soil mortar is injected from a channel bottom part and is filled while adjusting so that a face of the mud soil mortar rising so as to prevent eccentric pressure from acting on the core member 3 becomes constant, the core member 3 is constructed in a predetermined position with high precision. Moreover, since the mud soil mortar is filled after the core member 3 is constructed, it is unnecessary to add hardening delay agent to the mud soil mortar to obtain an underground continuous wall having high quality.

摘要： PROBLEM TO BE SOLVED: To provide a side-cut excavator which can continuously create an underground continuous groove while avoiding an obstacle present in the ground. SOLUTION: An excavating cutter 24 has a front end thereof, at which a bend being capable of vertically and laterally excavating in the ground is formed. When an obstacle 100 is present in the ground, the bend excavates the ground at locations above and under the obstacle 100. Thus, even if the obstacle 100 is present in the ground, an underground continuous groove 102 can be created without moving the location of the obstacle 100.

摘要： PROBLEM TO BE SOLVED: To speed up joint process of a cutoff sheet, and improve water stop perormance by simultaneously performing burying of the cutoff sheet and excavation of an impervious wall. SOLUTION: An end part joint 2 of the cutoff sheet 21 is connected to a starting end pile 31. A ditch is excavated by horizontally moving an excavator 10. The cutoff sheet 21 is stretched by being delivered from a cutoff sheet box 20 according to a movement. A hardener is spouted out while excavating the ditch, and is mixed with excavating earth and sand to form the impervious wall. The inside of the cutoff sheet box 20 and a joint box 25 is enhanced in cutoff performance by filling grout from a pipe 23. When the cutoff sheet 21 is wholly delivered, a new cutoff sheet box 20 is installed on a cutter block 12 to construct the impervious wall 1 having high water stop performance of a joint.
