摘要： PURPOSE:To prevent a re-excavation of the preceding excavation by destroying the soil left between the preceding excavation section and the succeeding excavation section of a soil landslide protection wall by the grout jetted from an excavator excavating the succeeding excavation section and making both excavation sections as a unit. CONSTITUTION:After excavating the underground by an excavator with multispindle augers, the preceding excavation sections 20A and 20B of the continuous underground wall are constructed by impregnating a grout. Upon constructing the succeeding excavation section 20C in adjacent to the preceding excavation sections 20A and 20B, the grout is jetted to the preceding excavation sections 20A and 20B from the excavator. Accordingly, when the preceding excavation sections 20A and 20B or the succeeding excavation section 20C are not precisely excavated, both excavation sections are jointed as a unit by destroying the soil left between two excavation sections. According to the constitution, a re-excavation of the preceding excavation sections 20A and 20B is prevented, and the working efficiency is enhanced.

摘要： PURPOSE:To eliminate useless boring and consumption of a material, by a method wherein a boring for a core-inserted pile is conducted down to a sufficient depth to allow the support of a wall body, and a boring for coreless pile is made down to only a depth being necessary to cut-off. CONSTITUTION:In a stratum containing a water impermeable layer around a pit excavation bottom, a boring for a core inserted pile 1 serving as a core is conducted down to a given depth from a pit excavation bottom level, and a boring for a coreless pile 2 serving as a wall part is made down to a depth to allow the slight touch of it to a water impermeable layer present around the pit excavating bottom. This enables boring of only a core part, supporting a wall body, down to a sufficient depth which results in enabling building of a rational soil sheathing wall matching a soil constitution and in eliminating an useless boring and consumption of a material.

摘要： PROBLEM TO BE SOLVED: To improve the safety by drilling a through hole opening to a tooth surface of one of chuck claws to a chuck main body, fitting an insertion pin to the through hole, and providing an insertion hole, to which the tip of the insertion pin is loose fit, on another chuck claw. SOLUTION: Chuck claws 12a, 12b are provided on the chuck main body 6a, a through hole 15 is drilled in the chuck claw 12b, and an insertion pin 16 is fitted to the through hole 15. An insertion hole 19 capable of giving a loose fit to the insertion pin 16 is drilled, a laterally placed pile 20 is inserted between the chuck claws 12a, 12b, and the insertion pin 19 is inserted to a pin hole 20a of the pile 20 in a freely rotatable manner. Next, the pile 20 is suspended and held vertically, the chuck claws 12a, 12b are fully closed and the pile 20 is moved to a driving place and driven. Thus, even though the pile is suspended in the state where the chuck is not fully closed, the pile is not likely to be detached from the insertion pin and therefore the safety can be improved.
