摘要： PROBLEM TO BE SOLVED: To reduce a working time and costs by moving a high pressure water jetting means downward for excavating along the circumferential face of an obstacle pile while jetting high pressure water, detaching the circumferential face of the obstacle pile from the soil sticking to the circumferential face for lower frictional resistance applied to the circumferential face of the obstacle pile from the soil, and extracting the obstacle pile upward. SOLUTION: Just above an obstacle pile K inserted into the ground G, a high pressure water jetting means 2 is hung by means of a hanging means. While high pressure water is supplied by a high pressure water supplying means 1 for excavating the ground G with high pressure water W jetted from a high pressure water jetting nozzle 10, the high pressure water jetting nozzle 10 is lowered and guided along the circumferential face of the obstacle pile K by means of a nozzle supporting and guiding body. In this way, the circumferential face of the obstacle pile K is disconnected from the soil sticking to it and frictional resistance applied to the circumferential face of the obstacle pile K from the soil during upward movement can be reduced, so that the obstacle pile K can be pulled out from the ground G.

摘要： PROBLEM TO BE SOLVED: To improve workability by excavating a ground by the high-pressure water of a high-pressure water supply flow path while pushing up excavated earth and sand upward by the compressed air in a compressed-air supply flow path. SOLUTION: The excavator A is composed of an excavating section 1, in which a high-pressure water feed pipe 27 and a compressed-air feed pipe 28 are juxtaposed, a hanging section 2, a high-pressure water supply section 3 and a compressed-air supply section 4. When soil and sand in a steel-pipe sheet pile connector, etc., are excavated, high-pressure water W is ejected from the high-pressure water injection nozzle 29 of the pipe 27, and compressed air (a) is ejected from the lower-end opening section 30 of the pipe 28. Vibrations are applied by a vibration-connecting body 5 and the excavating section 1 is lowered, soil and sand in an excavating space are excavated by high-pressure water W, and excavated materials are pushed up by compressed air (a). A compressed-air feed hose 12 is replaced with a mortar injection hose, and the inside of the excavating space is filled with mortar from the pipe 28. The excavating section 1 may also be formed in double pipes, in which the pipe 28 is disposed onto the outer circumference of the pipe 27. Accordingly, the efficiency of excavation and mortar injection works can be improved.

摘要： PROBLEM TO BE SOLVED: To improve the watertightness of a joint section by injecting grout into a grouting space through a grout bag. SOLUTION: A grout bag 4 is formed in a bottomed cylindrical shape by high-strength synthetic fiber yarn, and Tetron yarn is used in the vertical direction and ductility is reduced and dimensional properties are ensured and nylon special-processed yarn is employed in the horizontal direction and ductility is increased and adhesive properties onto a side wall are improved for preventing damage at the time of insertion and injection into a grouting space. Such a grout bag 4 is inserted into the grouting space by a grout-bag inserting bar 5 made of vinyl chloride, a grouting pipe 6 made of polyethylene is put into the grout bag 4, and grout 3 is injected into the grout bag 4 through the pipe 6. Accordingly, the watertightness of joint sections formed among the mutual joining end surfaces of sheet pile bodies can be ensured excellently.
