摘要： PROBLEM TO BE SOLVED: To construct a soil cement underground continuous wall having specific strength within a short period of time at a low cost in spite of characteristics of soil to be executed. SOLUTION: A soil cement underground continuous wall construction method is such that an underground continuous wall forming ditch 3 is excavated with an excavator while supplying stabilization liquid and, at the same time, that excavated soil is collected. Then, specific quantities of cement and water are mixed with the excavated soil to be collected to compound soil cement, and after the trench 3 is excavated, the compounded soil cement is poured into the trench 3 to substitute for the stabilization liquid to construct a soil cement continuous wall W by erecting heartwood 13 in the trench 3 after the substitution.

摘要： PURPOSE:To prevent soil columns from being positionally shifted from a forming estimation face, and improve precision for forming the columns by providing a rotary bearing for connecting a section near the lower end of an auger rod, with stabilizers to be pushed against a hole boring wall with a rotational force. CONSTITUTION:Five auger rods 3 are parallel-connected to each other in a positioned state, and a multiple shaft soil auger machine 2 provided with a driving gear 4 for rotating the auger rods 3, set on the upper sections of the rods 3, is fitted to be moved up and down on a tower 1. Besides, on the rotating directions of the augers 3, both the end augers are rotated in the same direction, and the central three augers are rotated in the same direction, and said two augers are rotated in the counter direction, and on connecting bearings 5 for connecting sections near the lower ends of the group of the auger rods 3, rotational. torsion suppressing stabilizers 6 to be pushed against hole boring walls W with a rotational force due to a rotational reaction force are fitted. Then, soil columns are prevented from being positionally shifted from a forming estimation face, and the soil columns are formed at high precision. Besides, the meters of a load meter, a speed meter, a depth gauge, an inclinometer, and the like are arranged, and hole boring excavation precision can be enhanced.

摘要： PURPOSE:To eliminate the need for foundation beam of great bearing forces by a method in which a main pile is set on the position of a column-line sheathing and used for sheathing in such a way that eccentric moment due to the deviation between the column center and the pile center is reduced. CONSTITUTION:Soil piles 1 are constructed to a deeper position than the final excavation bottom of an underground floor on the peripheral side of a construction site of building. A main pile A serving as sheathing, consisting of a steel tubular pile 2 of a length L similar to the pile 1 as an upper pile A1 and a PHC pile 3 as a lower pile A2 is set until the tip of the pile A2 reaches the bearing layer 4. A column-line sheathing B is consisting of the piles 1 between the main piles A is constructed, the inside ground of the sheathing B is excavated to construct an underground floor and also a terrestrial floor above the sheathing B. The need for foundation beam of great bearing force can thus be eliminated.

摘要： PURPOSE:To deposit bentonite on a steel material such an I-beam to a uniform thickness in the stage of electrodeposition bentonite on the steel material by charging horizontally the I-beam or the like in a longitudinal direction in a cathodic soln. cell which is provided with a cover in the upper part and contains a bentonite soln. and conducting electricity between the same and cathodes provided above and below said material. CONSTITUTION:A steel material 5 of I-beam or H-beam is put in a horizontal cathodic soln. vessel 1 contg. a bentonite soln., and is supported horizontally in the cell 1 by means of a support material 4 and auxiliary material 6 made of a non-conductive material. Four cathode bars 7 are disposed in the upper and lower parts of a web 5a of the steel material 5 and a cathode bar 10 is also disposed in the intermediate position of the web 5a in such a way that the distances between the respective bars 7 and the web 5a and flange 5b of the material 5 are made equal and that the distance between the bar 10 and the web 5a is made equal to the above-mentioned distance. Electricity is conducted at 40-150A/m current density between the bars 7 and 10 with the material 5 as an anode, and the bentonite soln. is kept stirred by the air blown from a nozzle 12, whereby the bentonite is deposited on the whole part of the material 5 to a uniform thickness.

摘要： PURPOSE:To surely effect insolubilizing treatment of contaminated soil, by a method wherein contaminated soil is mixed with a reducing agent to be subjected to insolubilizing treatment and the treated soil is mixed with cement to be subjected to solidification treatment. CONSTITUTION:Contaminated soil is charged in a hollow muck 1 and thrown in a skip bucker 4 from a hopper 5. The skip bucket 4 is taken up by the take-up winch subjected to a skip elevator 3 to charge the contaminated soil in a primary mixer 6. After mixing, the liquid chemical agent supplied from a weighing hopper 23 and water supplied from weighing hoppers 24, 25 are introduced from the introducing port of the mixer 6 through a pipeline 21 and the chemical agent such as the powder supplied from a weighing machine 26 is introduced from the introducing port of the primary mixer 6 through a pipeline 22 to perform mixing for a predetermined time. Next, the resulting mixture is charged in a secondary mixer 14 and mixed with cement and water to be discharged by a belt conveyor 39. By this method, insolubilizing treatment is performed surely.
