摘要： PURPOSE:To completely remove slime on foot-protected part by a method in which slime on the foot-protected part is wiped out by rotary brushes attached to a rotary plate and floated in mud water, and the slime is colled to the central part of the foot-protected part and pumped up to the ground's surface through a discharge hose. CONSTITUTION:A rotary plate 21 is turned through a power transmission mechanism 23 by a motor 22, and slime 14 on the foot-protected part 13 is wiped out by rotary brushes 16 attached to the plate 21 and floated in mud water. The slime 14 is collected to the central part of the part 13 by turning water stream caused by the rotation of the brushes 16, sucked into a suction port 25a by operation of a pump 18, and discharged to the outside of pit through a discharge hose 31 from the suction tube 25. The slime 14 on the foot-protected part 13 can thus be completely removed.

摘要： PURPOSE:To permit the treatment of slime in a short time by a method in which a fluid is jetted in an unfolded fan-like way from the jet flow path to the center of the pile bottom side of a slime treatment apparatus, and slime is floated on mud water and sent with mud water to the ground's surface. CONSTITUTION:A water pump 20 and a mixer pump 22 are operated concurrently to jet mud water taken into a housing toward a foot protected part 13 through a jet flow path (a) by the pump 22 in an unfolded fan-like way. Slime 14 floated in mud water is taken into the housing through a sludge suction path(b), and the slime and the mud water are sent up to the ground's surface through a sludge discharge hose 17. The slime deposited on the pile bottom side can thus be treated in a short time.

摘要： PURPOSE:To prevent outflow of soil of an inclined surface and also to improve the water holding property and air containing property by mixing at least water absorptive high polymer material in soil for forming the inclined surface. CONSTITUTION:A water absorptive high polymer material is mixed in soil E in an inclined surface forming area A. Water produced by rainfall R is absorbed by the water absorptive high polymer which is swollen, and the stickness is exhibited to hold the peripheral soil particles fast. When a short fiber material is mixed in soil E, the shearing strength can be increased in co-operation with the connecting action between the soil particles. Further, the high polymer material is increased in its volume like a gel, so that the water penetrating into the ground is cut off by the surface layer part. Thus, the outflow of soil due to rainfall can be prevented, and growing conditions of plants can be satisfied to promote the greening.

摘要： PURPOSE:To make uniform the strength of soil, by blowing compressed air in a frother dissolved in a liquid to generate bubbles and adding short fiber thereto and agitating and mixing it and after that, mixing it with soil and dispersing the fiber by the bubbles. CONSTITUTION:Air is blown in a dissolved frother 1 to generate a number of fine bubbles 14 in a bubble generator 3. The air bubbles are mixed with short fiber 13 with 2-10cm in the length of 1-30 denier in the fineness, in an agitator 8. In this case, the short fiber 13 corresponding to the weight as much as 0.2-1% of the dry solid of soil is mixed with the soil. The dispersed fiber 15 with air bubbles mixed by the agitator 8 is scattered from the discharge opening 16 to soil 28 through a hose 27. The short fiber is mixed with the soil 28 by the blades 26 of a stabilizer agitator 21 to prevent short fiber from being entangled and evenly scatter it to the whole. In this way, the equipment is miniaturized and lightened and further, the soil strength can be made uniform.

摘要： PURPOSE:To avoid the occurrence of poor replacement of slurry and bleeding and to check slurry from penetrating the ground by placing self-hardening slurry in a groove hole formed in the ground, and stirring the same while an accelerating agent is added thereto. CONSTITUTION:The ground 10 is dug to form a groove hole 16 while a stabilizer is filled therein, and a reinforcing member 18 such as an iron member, a reinforcing steel cage, PC plate or the like is built up in the groove hole 16. Self- hardening slurry 20 such as a material made by mixing at least one of clay, dug earth, sand, coal ash and an admixture, water and a solidifying agent is placed in the groove hole 16 to replace the stabilizer with the slurry 20. Subsequently, air is sent through an air compressor 30 and an air pipe 32 to generate air bubbles 28, thereby mixing the slurry 20, The remaining stabilizer is mixed with the slurry 20 and the groove hole 16 is filled with the above mixture to construct an underground continuous wall formed by a solidified material of the slurry which has no remaining stabilizer in the interior and little structural weak point.

摘要： PURPOSE:To efficiently improve the ground and shorten the construction period by arranging a heating means having a heating body in the recess formed on the ground with banking, further charging sand around the heating means, and supplying electric power to heat the heating body. CONSTITUTION:A recess 14 of prescribed depth penetrating banking 12 banked on the ground is formed. A heating means of long pillar-like lengthy body longer than the depth of the recess 14 and having a heating body extending in lengthwise direction is arranged so as to conform the lengthwise direction with the depth direction of the recess 14, and sand 18 is charged around it. Next, electric power is supplied from a power source 20 to heat the heating body, generated heat is conducted to the sand 18, and water content in the sand 18 is heated and evaporated, Accompanied with the evaporation, water content in the ground 10 around the recess 14 is let flow to the sand 18 in order to evaporate, and hence the ground 10 is dehydrated. Hereby, without generation of pollution-causing substance, ground improvement can be performed with simple construction and in a short period.
