摘要： PROBLEM TO BE SOLVED: To prevent a danger and the deterioration of work environment, and to miniaturize a base machine by a method wherein high-pressure water is injected from an excavation head, soil and sand are changed into excavated muddy water and lifted in a pit, soil and sand are separated and discharged and water is circulated and used. SOLUTION: An earth auger 2 is inserted into a pit 1, and an excavation bit 3 is installed to a head section and excavation is conducted. A guide post 11 is supported by a base machine 10, and the pit 1 is made perpendicular. High-pressure water is forwarded to the earth auger 2 by a high-pressure pump 20, and high-pressure water 22 is injected against a wall surface 23 in the ground from an excavation head through the inner tube of an earth auger shaft. Soil and sand on the wall surface 23 are excavated by infection, and slurry 24 is sucked by a slurry discharge pump 25. Slurry 24 is sent to a solid-liquid separator 30 through sections among the blades of the earth auger 2. Since mud is not discharged to the outside by separating slurry into water and removing earth 35 by the solid-liquid separator 30 and circulating and using a supernatant liquid 38, environment can be protected. The base machine 10 need not be scaled up.

摘要： PROBLEM TO BE SOLVED: To increase a supporting force by providing a ring-shaped nozzle ejecting a gas in the same direction surrounding a liquid-jetting stream, at the periphery of a high pressure liquid jetting nozzle of the head. SOLUTION: A ring-shaped gas ejecting nozzle 8 is formed at the periphery of a high pressure liquid jetting nozzle 5 of a head 1 to communicate with a compressed air passage 11. A gas ejecting hole 4 is closed. In the settling process of the pile, compressed air which has been conventionally forced to eject through the ejecting hole 4 is forced to eject through the nozzle 8, and compressed air is ejected from the periphery of the nozzle 5 to form an air entraining layer at the periphery of the liquid jetting stream. The frictional energy loss around the liquid jetting stream is reduced and the collision force of the jetting stream increases and the diameter of a pedestal to be formed becomes large. Instead of this, a high pressure liquid jetting nozzle constituted of a plurality of openings positioned close to each other is disposed at the same level in the axial direction of the head or at a position having a level difference in the axial direction of the head, and the ring-shaped gas ejection nozzle is provided at the periphery. In this way, a long term supporting force of the pedestal foot-protection pile can be increased.

摘要： PROBLEM TO BE SOLVED: To enable inner excavation of a pile having a small diameter by providing a plural winding screw blade, a central shaft like a double pipe, and a cemented tip edge tip and specifying their dimensions. SOLUTION: A screw 1 is provided with a plurality of blades 2, and a ratio of screw pitch P to outside diameter D of the screw is 2 to 8. The blade 2 cooperates with a shaft 3 to transmit effective twisting moment, and the pile installation by inner excavation of a pile having a small diameter becomes possible because it transmits a large torque even if its diameter is small. A fish tail 10 with cemented tip is attached to a head part 7 to enable digging of hard rocks. The length of the head part 7 is 1.5 meters or more so that a joint exists in the pile even if a bit receives a large bending force when a bulb is produced in a lower part of the pile and local stress does not act in the joint part. The central shaft 3 is a double pipe and is used in the digging due to low pressure air for discharging digged soil and high pressure fluid, stirring, pouring of cement milk, etc. Moreover, if an outside diameter of the pile having a small diameter is 450mm, its outside diameter D is 250mm or less.
