摘要： PURPOSE:To utilize paper sludge ash as a dehydrating and solidifying agent and dehydrate in the early stage by using specified sludge ash manufactured by burning paper sludge for an adding material and accelerating the dehydration and solidification of discharged mud formed following the construction work. CONSTITUTION:In the utilization method of paper sludge ash, the paper sludge ash composed of SiO2 of 35-55%, Al2O3 of 25-60%, MgO of 5-15% and CaO of 1-20% as main components formed by burning the paper sludge formed in the sheet manufacturing process is used as an adding material for acclerating the dehydration and solidification of discharged mud produced following the construction work using muddy water. For example, in the case the adding material is added into a pit 3 for mud 2 or a proper container filled with mud 2, the mud is desirably agitated by a hydraulic shovel, an agitator or the like. Although it is different in properties, water content and the like of mud, the mud is in the state of low fluidity within several hours to one day and can be transported by a dump truck 5 just as it is.

摘要： PURPOSE:To eliminate degradation of stabilizing liquid facilitate in use building-in and connecting work of a water cut-off sheet, and improve wokability water and cut-off ability. CONSTITUTION:A drilled groove 6 is formed in the ground while using wall stabilizing liquid 5, and a bag body 1 which is provided with respective male and female connecting metal fittings 2a, 2b having the length actually corresponding to the depth of the drilled groove on both side parts, and made of a liquid impermeable sheet, is built in against the drilled groove 6 in the contracted condition. Thereafter, filler is injected into the bag body 1, and a continuous cut-off wall W wrapped by liquid impermeable sheet is built in the drilled groove 6. The bag body 1 is a little shorter than the connecting metal fittings, the connecting metal fittings are made in the condition of downward projecting the suplus length by the relative difference, and a space M is formed under the bag body 1, in the condition after installing the cut-off wall. An injection rod is inserted through a vertical hole space P formed by means of the connecting metal fittings 2a, 2b so as to fill grout material A in the lower space M and perform foot fixing.

摘要： PURPOSE:To pulsatively impregnate chemicals into the ground without gaps among soil particles being blocked by the impregnated chemicals so as to give a satisfactory foundation improvement by impregnating the chemicals into the ground in an objective area while applying vibration thereto with the use of vibrators incorporated to a chemical feeder means or vibratos which are independently and individually plunged into the ground in the objective area. CONSTITUTION:Rotation transmitted from a rotary motor is transmitted through a rotary wire 11, a rotary joint 12 and a rotary shaft 13a to a vibrator 13 having a rotational center axis eccentric from its center of gravity so that the rotation causes the vibrator 13 to excite vibration which is transmitted to an outer feeder pipe 2 through its contact section composed of first and second packers 10, 16, and then it is transmitted into the ground. With the use of a boring driller, a hole is formed in a weak foundation ground in the objective area with the use of a casing tube 20 for protecting the wall surface of the hole. After the boring is completed, a bentonite group grout 21 is filled between the outer feeder pipe 2 and the ground. After the sleeve grout 21 is completely solidified, a feeder pipe 21 is inserted into the outer feeder pipe 1 so as to impregnated the chemicals into the ground while vibration is applied thereto in order to destruct the skeletal structure thereof.
