A sufficient penetrating material 4 is injected in the ground 1 within a specified range by the injection device 2. A saturated solution of calcium carbonate which easily forms crystals such as hydroxides or carbonates by the action with water in the ground 1 and which is stable for a long time and hardly deteriarates is used for the penetrating material 4. It increases an adhesive force by connecting mutually sand particles in the ground with calcium carbonate or the like. After the penetrating material 4 has been injected, the material 4 penetrated from the peripheral ground or the boring an into the ground 1 is recovered by a vacuum compressor or the like provided with the suction device 3.

摘要： PROBLEM TO BE SOLVED: To provide a system technique by which soil contaminated with toxic materials of organic chlorine compounds such as trichloroethylene, tetrachloroethylene of a precision machine manufacturing workshop or the like, is cleaned. SOLUTION: Two stages of upper and lower stirring vanes 6, 6' are secured at the tip part of a rod 5. The stirring vane 6' of the upper stage is made smaller sized than the stirring vane 6 of the lower stage. A mixture of a cleaning agent and air is injected into soil only from a pressure feed nozzle provided at a base part of the stirring vane of the lower stage to be fed by pressure. By making the stirring vane 6' of the upper stage smaller sized than the stirring vane 6 of the lower stage, stirring torque is reduced. Further, cleaned volatile gas raised from the stirring vane 6 of the lower stage is smoothly raised without being retarded so as to be efficiently recovered. Further, cleaning action is, as a secondary importance manner, added with the stirring vane 6' of the upper stage, and cleaning of the soil can be thoroughly achieved.

摘要： PURPOSE:To adjust apparent weight of a bank when banking is executed by after banking weight adjusting bodies downward in multiple stages on a base ground through a hose for fluid absorption/discharge, operating a fluid absorption/discharge device. CONSTITUTION:When banking is executed on a base ground 3, hollow weight adjusting bodies 1 that can adjust inner pressure are placed downward and set, and after a hose 2 is set thereto, a bank 4 is constructed and each weight adjusting body 1 is buried. After the hose 2 to which the weight adjusting body 1 of a number of stages that are equal to the height of the banking body and the set things are buried by the bank 4, a roof 6 is laid topmost. By the operation of a fluid absorption/discharge device 5 linked to a base end of the hose 2, air and so on can be attracted or compressed to the weight adjusting body 1. By the simple construction, apparent weight of a banking body can be adjusted, and even for a soft base ground, the effect thereby can be restricted to a lowest limit.

摘要： PURPOSE:To permit soft soil to be solidified and transported by a method in which a water-soluble cationic high molecular compound powder and a water-soluble anionic high molecular compound powder are added to soft soil of high water content. CONSTITUTION:A water-soluble cationic high molecular compound, e.g., aminoalkyl acrylate homopolymer, or the water-soluble cationic high molecular compound and a water-soluble anionic high molecular compound powder, e.g., polyacrylic acid or its salt, are added and agitated to soft discharged soil of high water content is construction work such as sludge press shield, mud water shield, underground continuous wall, foundation pile, etc. Free water in the soft soil is absorbed by the high molecular compounds to become gelled and solids are coagulated and given a tacky property. The whole of the solid can thus be solidified under a condition that free water is kept in the voids of the coagulated solids.
