摘要： PROBLEM TO BE SOLVED: To provide press-in techniques for a casing for use in an all-casing construction method, capable of pressing the casing into a great depth without digging irrespective of the soil condition of the ground. SOLUTION: This press-in device for a casing is used in an all-casing construction method wherein a vertical hole is drilled by use of a casing comprising an end casing C provided with an inner cutter C2' and an outer cutter 2", and a joint casing connected thereto. The end casing C is provided with an auxiliary cutter D for digging an inner peripheral area inside the end casing C inward of the inner cutter C2', and an inner peripheral fluid ejection pipe 11 having a nozzle 11C from which pressure fluid is ejected into an annular inner peripheral area dug by the auxiliary cutter D; the pressure fluid is ejected into the annular inner peripheral area dug by the auxiliary cutter D, so that the soil dug out of the area is plasticized and fluidized along an overall periphery near the inner peripheral surface of the lower part of the end casing C to reduce the resistance of the casing to pressing-in.

摘要： PROBLEM TO BE SOLVED: To provide a vertical hole digging method capable of efficiently discharging soil and sand inside a large diameter casing in the vertical hole digging method in which the casing is held through a small diameter adapter for digging. SOLUTION: A vertical hole digging device comprises an adapter 4 having a small diameter, long holding part and capable of connecting a large diameter casing, a main band 5, a main band 5, a rotatably driving device to rotatably drive the main band 5, a thrust cylinder 6 to raise and lower the main band 5, and a sub band 9. After the vertical hole digging device is mounted on a frame 3 movably in lateral direction, the main band 5 on which the holding part of the adapter 4 is held is rotated and lowered while the holding part is passed appropriately from one hand to the other so as to press the casing 2-2 into the ground. Next, after the adapter 4 is separated from the casing 2-2, while the main band 5 is passed from one hand appropriately to the other in association with the sub band 9, the adapter 4 is raised, and then the shaft digging device is moved horizontally so that, for soil exhaustion, a hammer grab 15 can enter directly into the casing 2-2 without passing through the adapter 4.

摘要： A control valve device (16) comprises two direction control valves (20, 21). The direction control valve (20) has an extension-side variable throttle unit (20c) and a contraction-side throttle unit (20d). The direction control valve (21) has an extension-side variable throttle unit (21c) and a contraction-side throttle unit (21d). A controller (35) determines that a hoist cylinder (10) is approaching a stop position, when the hoist cylinder (10) extends to raise or lower a vessel (3) and the hoist cylinder (10) is approaching the stop position. Based on this determination, the controller (35) uses the variable throttle units (20C, 20D) to variably adjust the flowpath surface area of the direction control valve (20) or uses the variable throttle units (21C, 21D) to variably adjust the flowpath surface area of the direction control valve (21), so that the expansion/contraction speed of the hoist cylinder (10) is increased or decreased according to the weight on the vessel (3) side.
