摘要： PROBLEM TO BE SOLVED: To provide an automatic control method for a soil improving machine equipped with a wire-operated excavation accuracy controller, which carries out automatic control operation of a soil improving machine, based on a technique of a skilled operator when a lap-type soil column row is sequentially constructed by the soil improving machine.
SOLUTION: In first soil improving work, a hydraulic jack remote-controller is manually operated by the skilled operator, based on data of an automatic measuring device, and an excavation control pattern is created and registered based on measured data depending on the manual operation. In second and subsequent soil improving work, with respect to an area adjacent to an area which has been soil-improved in the previous work, a control signal according to the previous excavation control pattern registered in a work control device, is transmitted to a wire-operated excavation control section and an excavation driving control section, to thereby carry out automatic control operation of the soil improving machine.

摘要： PROBLEM TO BE SOLVED: To provide a soil improving device, by which a ground is excavated in the vertical downward direction and a stabilizer is injected into excavating soil at an original place and agitated and mixed and the soil is improved and treated, and its agitating excavation shaft. SOLUTION: A lower bracing is constituted in such a manner that roller type guide mechanisms rolled along a guide pipe for a leader are installed at the upper and lower positions of a sliding metallic material slid along the guide pipe and a plurality of receiving rollers rotatably supporting the peripheries of each rod are mounted on a rod supporting section. A connecting bearing is constituted in such a manner that a joint shaft connecting the rods and the agitating excavation shaft in a series in upper and lower sections is supported rotatably by a plurality of roller bearings and the roller bearings are sealed hermetically in a watertight structure. The agitating excavation shaft is configured in such a manner that a leading excavating cutter downwards projected in long size so as to leading-excavating the ground in the vertical downward direction is mounted.

摘要： PROBLEM TO BE SOLVED: To improve integrated strength of mutual wall bodies of a crossing part by forming a width thickness of either one improved earth wall of improved earth walls preceding in or succeeding to execution work among crossing improved earth walls in a thick wall shape expanded in the crossing part. SOLUTION: To a preceding improved earth wall 10, a width thickness of an improved earth wall 11 of postexecution work is formed in a thick wall shape expanded in a crossing part X. Hydraulic jacks longitudinally movable when looking at a guide frame in a plan view are provided by two units on the left and right of a lower part. Next, when forming an inclined part E of the improved earth wall 11 of postexecution work, a guide frame is slantingly executed by extending the hydraulic jacks. Similarly when forming an inclined part F, a guide frame is slantingly executed by extending the hydraulic jacks. Thus, a process of the inclined parts E, F is compositely executed, and in the improved earth wall 11 of postexecution work, the crossing part X with the improved earth wall 10 of preexecution work is formed in a thick wall shape expanded in a width thickness of the improved earth wall 11 to thereby easily provide a highly strong and reliable crossing wall.

摘要： PROBLEM TO BE SOLVED: To provide a crossing wall formation method by a continuous mixing treatment construction method capable of utilizing the characteristics of ground improvement by the continuous mixing treatment construction method and applying a connection structure so that integration strength of mutual wall bodies in a crossing part can be increased sufficiently. SOLUTION: A digging mechanism is pulled up when the digging mechanism forming an improved earth wall W2 by posterior work execution reaches a side face in front of an improved earth wall W1 which is constructed previously to pass it in such a way that an upper part of the improved earth wall W1 by previous work execution is cut out partially, and the digging mechanism is inserted down to the original depth again when it reaches a face on the opposite side of improved earth wall W1. After that, continuous formation of the improved earth wall by posterior work execution is continued.
