摘要： PURPOSE:To allow the banking to exert the function resisting the soil pressure from the outside as a block, stably support the banking, use the viscous soil as the back-filling material of a wall face material, facilitate the design calculation for the safety of the banking, facilitate the execution and reduce the cost. CONSTITUTION:Multiple tensile members are fitted to the back face 10 of a wall face material 4 on one end side at a specific interval in the vertical direction, the tensile members 12 are arranged in the horizontal direction, and the tensile members 12 are fitted to resistance members 16 on the other end side respectively. The banking at portions of the resistance members 16 is solidified by a solidifying agent to form a back face wall 20 in the vertical direction.

摘要： PURPOSE:To reduce the banking width, facilitate the execution and reduce the cost by fitting multiple tensile members to the back face of a wall face material on one end side, and fitting them to meshy resistance members buried nearly in parallel with the wall face material on the other end side respectively. CONSTITUTION:Wall face material blocks 4a are horizontally mounted, stacked, and connected in the vertical direction. The lowest section is supported on a foundation 8, and a wall face material 4 is erected on the ground 2. Multiple tensile members 12 are fitted to the back face 10 of the wall face material 4 on one end side with fitting tools 14. They are fitted to meshy resistance members 16 buried with the lower section in the banking 6 nearly in parallel with the back face 10 on the other end side with fitting tools 18 via insertion members respectively. The banking 6 is put and rolled on the tensile members 12 into a stratum state in sequence. An anchor-reinforced clayey wall 28 is formed, and pressure bulbs 24 are generated at portions of the resistance members 16 respectively. The soil pressure from the outside is resisted as a block, the design calculation for safety is facilitated, execution is facilitated, and the cost can be reduced.

摘要： PURPOSE:To enhance improvement effect, also on the ground of high water- permeability including a gravel stratum, and heighten strength after improvement, specially, and enlarge an improvement diameter. CONSTITUTION:Through an injecting pipe 1 inserted into ground, from its tip section, the instantaneously bonding grout S of the solution type or the suspension type of a concreting time equal to or shorter than 60 seconds is injected and after that, from its injecting position or a tip side before the position, the reinforcing grout R of a suspension type with the concreting time longer than that of the instantaneous bonding grout S and with great homo/gel strength is injected. After that, from the injecting position of the reinforcing grout R or a tip side before the injecting position, the permeable grout L of a solution type with a concreting time longer than that of the instantaneous bonding grout S is injected.

摘要： PURPOSE:To enable rotation and thrust excavation to be freely selected by interposing an excavating thrust measuring sensor during non-transmission of rotational torque and an excavating torque sensor during non-transmission of excavating thrust in a rod shunk provided, additionally with an excavating bit axially on the end and with a penetrating cone on the inside end additionally. CONSTITUTION:A rod 4 is divided into the upper and lower rods 7, 7' which are interconnected to each other through a jaw clutch 8. The lower rod 7' is provided with a penetrating cone 15, on its lower inside end fixedly in one body while being axially equipped on the distal end with an excavating tool 12. A load cell 16 as an excavating thrust measuring sensor is provided between the upper and lower opposed faces of the upper and lower rods 7, 7' and an excavating torque sensor 17 is provided on a surface 180 deg. away from the surface of a jaw clutch 8. The rod 4 is rotated forward for rotational excavation. Then, excavating resistance is detected by the load cells 16, 17 to input the detecting signal as FM electric wave 20 into a computer 23. Thus, the strength of the foundation can be accurately measured.

摘要： PURPOSE:To exactly recover exhaust air, by fitting an air recovery hood at a position slightly higher than the stirring blade of a rotary shaft, and by providing the lower opening of the air recovery hood with an automatically opening and closing cover. CONSTITUTION:Ground-improving agent is jetted along the rear surface of a stirring blade 4 from a nozzle 5 and is spread in a ground, and exhaust air enters an air recovery hood 7. Then, a plurality of permeable slots 8 are bored in the peripheral wall of a rotary shaft 1 surrounded with the hood 7, and the internal space of the hood 7 is communicated with an air recovery path 9 in the rotary shaft 1. The skirt of the hood 7 is enlarged so that air may easily enter therein, and the lower opening is provided with a cover 10 opening and closing automatically along with the vertical movement of the rotary shaft 1. By this method, exhaust air enters the air recovery hood through a short in-ground path, and the probability of the existence of residual air in the ground is small, and the improved ground of high quality can be created.
