摘要： PROBLEM TO BE SOLVED: To contrive to reduce cost by setting a specified amount of earth removal per unit time in conformity with a geological condition of a soil to be improved and forming a screw lot so as to conform with the specified amount of earth removal by changing a layout spacing of a screw blade. SOLUTION: The amount of supply of cement slurry in a hardening agent supply mechanism 23 is controlled in conformity with a geological condition of a soil G while screw rods 12 are formed to provide a specified amount of earth removal by setting a layout spacing (d) between screw blades 19b provided in a shaft 19 with a screw to a specific value. Then, in the case of a geological condition which demands for a large amount of supply, the layout spacing (d) is minimized, thereby moving a proper amount of excavated earth and sand upward while in the case of a geological condition which calls for a small amount of supply, the layout spacing (d) is maximized, thereby preventing the excavated earth and sand from moving upward. It is possible to optimize the amount of earth by selecting an optimum value for the layout spacing (d) and inhibit a rise and drop in the earth pressure and reduce cost by removing the soil in conformity with the geological condition.

摘要： PROBLEM TO BE SOLVED: To easily carry out a removing work for soil corresponding to the geological condition, by providing shaft parts with screws and shaft parts without screws having appropriate lengths respectively in advance in accordance with the geological condition of the improving ground and constituting the screw rod to obtain a specified volume of removing soil. SOLUTION: A screw rod 12 is constituted to make long the shaft 19 part with screws in a geological condition to supply much solidifying agent and to make long the shaft 20 without screws in a geological condition to supply only a little solidifying agent. The screw rod 12 is rotated at a constant speed while supplying a certain quantity of solidifying material corresponding to the geological condition of the improving ground by a solidificer-feeding mechanism 23 and rotating the screw rod at a constant speed. In this way, the supply volume of the solidifying material and the removed volume of excess soil in the ground meet the geological condition. And hence, increase or decrease of earth pressure can be regulated by the removal of soil corresponding to the geological condition and the ground can be improved in low cost.

摘要： PURPOSE: To make it possible to ensure vertically of rotary shafts when they are penetrated by changing their rotational directions every proper penetration depth when the rotary shafts are penetrated into the ground, mounting stirring wings extended in the radial direction to the lower ends of the rotary shafts in a rotatable manner, and making it possible to change an inclination to a specific angle. CONSTITUTION: Two rotary shafts 2 are monolithically suspended to a construction machine main body 1 in a liftable manner, and stirring wings 3 are projected to lower layers of the rotary shafts 2 in the radial direction in a turnable manner. Rotational directions of the rotary shafts 2 and 2 when penetration is made are alternately changed to A direction (forward) - B direction (reverse) every penetration depth. When the rotary shafts 2 and 2 are pulled out, the rotational directions of the rotary shafts 2 and 2 are changed so as to make reverse to when the penetration is made to stir the loose soil uniformly. The base sections of the stirring wings 3 are mounted to the lower ends of the rotary shafts 2 in a rotatable manner, and the inclination in the turning direction can be changed with a turning mechanism. When the rotary shafts 2 are reversedly revolved, the inclination in the turning direction of the stirring wings 3 is made to the same one as that of the penetration, and the lowering of penetration efficiency can be prevented.

摘要： PROBLEM TO BE SOLVED: To enhance the overall efficiency of civil engineering work by enabling more rational transfer and to greatly reduce facility costs without restriction of the device installation area. SOLUTION: Sediment (a) of dredging or the like is conveyed by a hull 1, and the sediment (a) conveyed is mixed with a solidifying agent (b) and transferred to a reclaimed area 2 by a conveying means 30 to reclaim the area. In that case, a mixing process S3 whereby the soil in the hull 1 is mixed with the solidifying agent (b) by use of a mixing means 12 to form a mixture inside the hull 1 at a predetermined site near the reclaimed land 2 to which the soil is conveyed by the hull 1 and a moving process S4 whereby the mixture (c) in the vessel 1 is conveyed to the conveying means 30 provided outside the hull 1 are carried out.

摘要： PROBLEM TO BE SOLVED: To enhance construction properties by providing a penetration/drawn shaft with measuring instruments for inclination angles in two directions, helix angle, and depth, and computing and displaying the position coordinates and helix angle of the end of the shaft. SOLUTION: A rotating shaft 1 having stirring blades 2 has its inclination angles to the vertical direction and its helix angle measured by means of measuring instruments mounted in a sensor 4. The amount of movement of the shaft 1 in the vertical direction is measured using a depth indicator used to measure the wire length over which the shaft 1 is suspended from a leader. Next, the position coordinates of the end of the shaft 1 are calculated from the measured value of a two-way inclinometer using a computation means for every predetermined amount of movement of the end of the shaft 1, and the coordinates and helix angle of the end of the shaft 1 are cumulated for every movement of the end of the shaft 1. The position coordinates of the shaft end or the shape of an underground construction is displayed on a display. Therefore, the penetration position of the end of the rotating shaft under the ground can be detected every minute, the helix angle formed in the underground construction can be detected according to penetration depth, and the quality and shape of the construction can be evaluated precisely.

摘要： PROBLEM TO BE SOLVED: To greatly reduce the facility costs by improving overall earthwork efficiency by rationally performing the transport, treatment and earth filling and, at the same time, without being restricted by the area for installing the equipment. SOLUTION: Sediment (a) from dredge or the like is transported by a barge 1, and this transported sediment (a) and a solidifier (b) are mixed together and treated earth (c) is produced and the treated earth (c) is moved to an earth filling area X and then filled. In this case, there are several steps including a process for transporting sediment (a) from dredge or the like to a predetermined place (w) rear the earth filling area X by a barge 1, a mixing process for making treated earth (c) by mixing a solidifier (b) to the transported sediment (a) by using a mixing means 12 from the external of the barge 1 and a filling process for placing treated earth (c) from the barge 1 to sea floor or the bottom of the water at a place x1 for discharging the treated earth.

摘要： PURPOSE: To improve workability by a method wherein when a soft ground is consolidated, a load amount at the end part of a load area is maximized and a level is lowered in a stair-form manner to the inside. CONSTITUTION: A loading body 4 is high at the end part of a loading area and reduced in a stair-form manner toward a central part. A load at the end part of the loading is increased and settlement of the end part of the load area is increased as shown in a ground settlement curve 5. A loading body 4 is formed in such a manner that rigid rubber bags are filled with water and stacked in a desired shape. This constitution sufficiently ensures a ground settlement amount of the end part of the loading area without extending the load area to the outside of a ground structure building projected area, decreases the construction range of a vertical drain I for sand piles, and reduces a cost.
