摘要： PURPOSE:To raise the shear and conpressive strength of a soil by mixing a short fiber material composed of a synthetic fiber, a synthetic resin, or a metal fiber with the soil and sand in such a way that the short fiber material is irregularly dispersed and orientated in the soil and sand, and also supply the reinforced soil simply and at low cost. CONSTITUTION:A reinforced soil 2 is placed on the back side of a retaining wall 1. The reinforced soil 2 contains 5wt% short fiber material composed of a synthetic resin fibers 0.05mm. in thick, 1.0mm. in width, and 50mm. in length, with an oblong cross section, dispersed and orientated irregularly in soil. When a condition that the soil and sand are stabilized and loads are equally applied on the soil and sand is reached, a frictional action is acted between the soil and the short fiber material and the short fiber material is linearly dispersed and orientated by the tensile force of soil and sand during the moving and stabilizing processes. Thus, during the moving process of soil and sand, a high tensile strength is exhibited and highly uniform shear and compressive strengths are produced.

摘要： PURPOSE:To prevent slurry from being separated from, by casting slurry-formed casting material kneaded with added water, forcibly into water, through a casting pipe with a built-in screw conveyor. CONSTITUTION:A.F.material C agent, and B.N.agent are fed in the shape of a layer from respective hoppers 12, 13, 14 onto a belt conveyor 15. After that, casting materials are mixed on the conveyor 15 by a mixing buffle plate 16 and are fed to a casting pipe 1. After that, in the continuous mixer section 2 of the casting pipe 1, the materials, together with water injected from the water injecting slot of an agitating wing 4, are kneaded by the agitating wing 4, and are fed to a tremie pipe 3 by a spiral wing 5. Besides, the slurry-formed materials are fed by the spiral wing 5, and are jetted to the sea bottom from the jet port 3a of the tremie pipe 3, and are cast.

摘要： PURPOSE:To form a homogeneous ground-improving column-formed body, by pressing coal ash slurry in ground through a tremie pipe, to pull up a casing pipe and the tremie pipe. CONSTITUTION:In a casing pipe 2, a tremie pipe 1 is set, and a packer section 3 coming in close contact with the internal side of the lower end section of the casing pipe 2 is set, and a cloth bag 4 in close contact with a section between the casing pipe 2 and the packer section 3 is set. Then, the tremie pipe 1 and the casing pipe 2 are driven to a specified depth, and after that, the tremie pipe 1 and the casing pipe 2 are pulled up at the same time and slurry is discharged into the cloth bag 4. In a state that the cloth bag 4 is filled up with the slurry, a ground-improving column-formed body is formed in ground.

摘要： PURPOSE:To enable strong reinforcing treatment excellent in durability to be executed, by filling up a long cloth bag with hardening material, and by executing filling on the bag after the bag is laid on poor subsoil in the shape of a raft. CONSTITUTION:Permeable synthetic fiber cloth bags 2 are filled up with fillers with the coal ash of main material and added cement and plaster, and the fillers are solidified, and reinforcing materials 3 are formed. Then, no poor subsoil, a sheet 4 is laid, and on it, the reinforcing materials 3 are laid in the shape of a raft, and after that, filling 5 is executed. As a result, the poor subsoil can be easily reinforced, and strength is easily controlled.
