摘要： PURPOSE:To install a drainage material without damaging the drainage function of the drainage material by a method wherein the drainage material is inserted into a hollow guide rod, a fixing tool is mounted detachably at a front end and the rod is connected to the drainage material and penetrated into the ground. CONSTITUTION:A drainage material 4 is inserted into a hollow guide rod 6. A fixing tool 7 connected to the drainage material 4 is set up at the front end of the rod 6 at that time. Projections 10 are protruded from the fixing tool 7, and abutted against the keys 11 of the rods 6, thus allowing a turn with the rod 6 and extraction and detaching. The front end of the rod 6 is pushed against the ground 2, rotated and penetrated in the horizontal direction. The rod 6 is penetrated in specified depth, the rod 6 is extracted, and the fixing tool 7 and the drainage material 4 are left in the ground 2. The head of the drainage material 4 is covered with a drainage jacket pipe 12 and opened on the outside of the face of a slope at that time. Accordingly, the function of the drainage material 4 can be displayed positively without damage, thus also improving the operating efficiency and safety of installation.

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.
