摘要： PROBLEM TO BE SOLVED: To quickly make a correction during drilling by advancing only an inner pipe in the hole bend correcting direction from the present drilling tip position while an outer pipe is stopped, and drilling a hole bend correcting guide hole in an undrilled area. SOLUTION: When a hole bend occurs during drilling, the intrusion and rotation of an outer pipe 1 is stopped, and only an inner pipe 2 is advanced deeper from the present drilling tip position. A hole bend correcting guide hole is drilled to the hole bend correcting direction in an undrilled area. The inner pipe 2 is stopped, the outer pipe 1 is advanced to the relative position to the inner pipe 2, then drilling is again conducted by a double pipe rod. The outer pipe 1 is naturally advanced along the correcting guide hole by the existence of the hole bend correcting guide hole at the front of the tip of the outer tube 1, and the hole bend is automatically corrected. The hole bend correction is made at any time during drilling, and the hole can be drilled with high execution accuracy.

摘要： PURPOSE:To eliminate deterioration of a stabilizer to be used, facilitate erecting and connecting work of a cut-off sheet, and construct a continuous wall excellent in workability and cut-off property. CONSTITUTION:An excavated groove 6 is formed in the ground using a wall stabilizer 5, and a bag connection sheet 1A with an end fixing member 3 and connecting fixtures 2a is erected in the excavated groove 6 in contracted condition. Next, a water sealing filler 7 is charged into the pipe of the end fixing member 3 to fix it. Then filler is charged into the bag bodies 1a, 1b,...1j in that order to construct an end water sealing wall W1 surrounded by a non- permeable sheet in the excavated groove 6. A bag connection sheet 1B with connecting fixtures 2a and 2b at its both ends, respectively, is erected in contracted condition and with one connecting fixture 2b fitted closely into a free end side connecting fixture 2a on the existing water sealing wall. Then, in the same manner, filler is charged into the bag bodies 1a, 1b,...1j to construct a continuous general section cut-off wall surrounded by a non-permeable sheet in the excavated groove.

摘要： PURPOSE:To perform dehydration quickly, and increase strength, and lower a disposal cost by adding additive material made from incinerated sludge in a paper manufacturing plant, with contained specific component, to waste sludge along with construction work using sediment and water. CONSTITUTION:The ashes of incinerated paper sludge to be generated in a paper manufacturing factory are burnt up again at 800-950 deg.C for 30-40 minutes, and the additive material of a pulverulent body with the main body of SiO2: 35-55%, Al2O3: 30-40%, MgO: 5-15%, and CaO: 1-10%, and with contained Fe2O3 or the like is prepared. After that, the additive material of 50-500kg, preferably, 15-450kg for 1m of waste sludge in the construction work using sediment and water are added to be agitated. Then, with the porous additive material, solid/ liquid separation is promoted, and a water content quantity is lowered in a short time, and consistency and strength sufficient for carrying are obtained, to be quickly carried and discharged. Besides, when sludge to be carried is set with the main body of bentonite, then it is desirable for slurry with the added additive material to be pressed for dehydration with pressure equal to or higher than 1kgf/cm .
