摘要： PROBLEM TO BE SOLVED: To securely expand and shrink a digging stirring blade provided at many steps or a blade for preventing turn together with the digging stirring blade by a simple expansion and shrinkage mechanism in a soil improvement machine so as to improve the mixing property of cement milk and soil greatly. SOLUTION: A digging rotary shaft 1 for a soil improvement machine has a double pipe structure consisting of an inner pipe 2 and an outer pipe 3, and the inner pipe 2 and the outer pipe 3 are arranged in such a way that they can rotate integrally and slide relatively in the axial direction. Digging stirring blades are arranged at many steps at an interval in the axial direction in the outer pipe 3, and a basic part of the digging stirring blade is supported on the outer pipe 3 in such a manner that the digging stirring blade can rotate freely in the direction in which its outside diameter is expanded and shrunk. The digging stirring blade 5-1 on a tip side of the outer pipe is expanded and shrunk due to the slide of an expansion and shrinkage guide member 8 provided in a tip part of the inner pipe 2, and the digging stirring blade 5-2 on a basic end side of the outer pipe is expanded and shrunk due to the slide of a guide mounting member 12 and an expansion and shrinkage guide member 11 which are provided in the inner pipe 2 and can move in the axial direction in a slit 13 of the outer pipe.

摘要： PURPOSE:To improve the strength and execution property by intruding a cylindrical core material into a columnar improving body stirred and mixed with a solidifying agent into soil, and sticking the improving body to the inner and outer peripheries of the core material. CONSTITUTION:The upper section of a gentle slope 21 is cut off to form a cut slope 20 at such a gradient that a cut slope section is not collapsed. An excavating/stirring device 30 is rotated, excavating blades 32 are intruded into the slope 20, a solidifying agent is discharged from the tip of a hollow rod 31, and the solidifying agent and excavated soil are stirred and mixed to form a cylindrical improving body 11. The device 30 is drawn, and a cylindrical core material 12 is intruded into the improving body 11 before hardening to form a reinforcing body 10. These processes are repeated to expand the slope 20 in sequence, and a retaining wall is constructed on the slope 20 as required. The inner and outer peripheries of the core material 12 serve as friction resistance faces, the draw resistance force can be increased, resistance bending moment can be increased because of the cylinder, bending/shearing resistance force can be increased by the synthetic effect with the improving body 11, and the loosening of the peripheral ground during execution can be prevented.

摘要： PURPOSE:To make a rod function as a load resistant body by leaving and fixing the rod in an agitated mixed reinforcing body formed by agitating and mixing excavated soil and a solidifying body in the ground while excavating the ground. CONSTITUTION:A solidifying material is supplied through a shaft passage together with excavated soil by an agitating vane 13 of an excavating agitating hollow rod 1, and an agitated mixed reinforcing body 2 is constructed. When it reaches a prescribed depth, the rod 1 is separated from a boring machine 3, and is left in the reinforcing body 2. After the reinforcing body 2 is hardened, a rotary shaft 11 of the reinforcing body 2 projecting to the ground surface side is fixed to a concrete wall body 5 or the like. In this case, an excavating vane 12 and the agitating vane 13 of the excavating agitating hollow rod 11 function as a load resistant body to check slipping-out of the rod 1, and exhibit extremely large pullout resistance force. Thereby, since the possibility that agitated mixed soil before it is hardened slips out of a hole together with the excavating agitating hollow rod is eliminated, it is constructed safely while avoiding looseness of the peripheral ground or ground subsidence.

摘要： PURPOSE:To provide a thick diameter rod for reinforcement ideal for civil work and construction fields by applying deforming work to the surface of a bar body formed of the fiber bundle of organic synthetic fibers impregnated with resin so as to form a single line, and bundling plural single lines in the parallel state. CONSTITUTION:A fiber bundle formed by arranging numerous organic synthetic fibers is impregnated with synthetic resin and hardened to form a bar body, and deforming work is applied to the surface of the bar body to form a single line 1 of 3-20mm in the maximum outer diameter. Plural single-lines 1 are then bundled in the parallel state to form an organic syntehtic fibers made thick diameter rod of 20mm or more in the maximum outer diameter. This thick diameter rod is then bound by applying resin and hardening it or using cross-wound thread 2, a band, a string, a tape, or the like. The organic synthetic fiber used in this case is of a polyvinyl alcohol group, a totally aromatic polyester group, a totally aromatic Aramid group, a polyacrylonitrile group, a polyolefine group, or the like.
