摘要： PURPOSE:To intend better constructionality and lower cost with light-weight and cheap banking material by using as base material powder comprising coal- ash powder and cement powder cellular concrete which is mixed with the specified ratio of bubbling agent to water by wt. CONSTITUTION:Base material powder with the ratio of coal-ash powder to cement powder by wt., 1-5, is mixed with 0.5-2% bubbling agent and 40-50% water by wt. to define slurry wt. per unit volume as 0.8-1.05t/m for forming light-weight cellular concrete. Then, after a hole 2 as large as the bottom face of banking is excavated in the ground 1 to place concrete or spreaded sand 3 in the hole 3, a mold 4 is assembled thereon to place a slurry 5 for the cellular concrete in the mold 4. Additionally, with repeated pile-up of the mold 4 and placement of the slurry 5, the slurry 5 is hardened to construct a desired height of banking.

摘要： PURPOSE:To enable the revolutionary motion of an impeller with agitation resistance and to simplify the structure of an agitator by fitting a transverse supporting arm which receives torque caused around a driving shaft by means of agitation resistance exerted to the rotating impeller so that the transverse supporting arm can not be moved to the axial direction of the driving shaft and fitting an agitating shaft fitted with the impeller to this arm so that it can not be moved to the axial direction. CONSTITUTION:The rotation of a driving shaft 2 is transferred to the agitating shafts 4, 5 via the gears 6, 7, 8 and the agitating shafts 9 are subjected to rotational motion and a mixture to be agitated which is introduced into an agitation tank 1 is agitated with the impeller 10 fitted to the lower end thereof. In this case, since agitation resistance due to the mixture to be agitated acts on the impellers 10, torque caused around the driving shaft 2 is generated in a supporting arm 3 by means of this agitation resistance. As a result, the agitation shafts 9 are subjected to revolutionary motion around the driving shaft 2. The mixture to be agitated is uniformly agitated in a range over all regions of the agitation tank 1 with the impellers 10 of the agitating shafts 9 which are subjected to revolutionary motion while performing rotational motion in such a way.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of the piping works of a new culvert by making a pilot cutter device travel into an existing culvert prior to the excavation by an excavator, crushing and excavating the existing pipe or culvert and pressing the new pipe or culvert into the excavated section. SOLUTION: An excavator 1 is composed of a propulsive guide 13 propelling the excavator 1 along a cylindrical casing 10, in which both a front end face and a rear end face are opened, a ring cutter 11 and an existing culvert 2 and a new pipe engaging section 14, with which a new pipe or culvert 3 is engaged. A pilot cutter device is made to travel in the existing culvert 2 prior to the bending-stretching propulsion of the bending-stretching propulsive device 1, and two strips or more of broken-line strip slit grooves 2a are formed to the peripheral wall section of the existing culvert. On the other hand, an excavating bit 23 having the same diameter as the new culvert 3 is installed at the front end of the ring cutter 11, and excavated muck obtained by excavating the periphery of the existing culvert 2 in a ring shape is taken into a communicating space P. Soil and sand between the existing culvert 2 and the new pipe or culvert 3 are crushed secondarily by an internal cutter 24, but the places of the front ends of soil and sand are positioned at the place of the external surface of the existing culvert 2.

摘要： PROBLEM TO BE SOLVED: To prevent clay from flowing out and ensure an efficiency of dehydration by installing a sheet such as nonwoven fabric having an impermeable portion of clay particles disposed inside and outside of the face on the adverse portion of a pouring opening of a bag body comprising water permeable cloth. SOLUTION: An upper bag body 2 and lower bag body 3 being sewed mutually are produced of water permeable cloth, and a pouring opening 4 is put on the upper bag body 2 for pouring high moisture content clay. At that time, on a part opposed to the pouring opening 4 in the inner face of the lower bag body 3, a nonwoven fabric sheet is set as a sheet 5 for forming a nonpermeable portion of clay particles. Also, the sheet 5 are formed into various shapes such as a rectangle, circle, or the like, the size is made larger than the opening area of the pouring opening 4 allowing for an expansion of stream of the high moisture content clay. The sheet 5 is fastened onto the lower part bag body 3 by suture or adhesion before suturing the upper and lower bag bodies 2, 3. Thus, if the high moisture content clay is poured at high speed, the clay can be controlled in its outflowing, and an efficiency of dehydration can be precluded from lowering.

摘要： PROBLEM TO BE SOLVED: To conduct a low pollution vegetation by placing high moisture content clay into a cloth bag body, bagging and dehydrating the high moisture content clay, and producing the bag body with noncorrosion fiber of synthetic fiber and corrosion fiber such as regenerated fiber formed into a mesh. SOLUTION: Materials of warp 11 and weft 12 are to be noncrossion polyester fiber filament yarn 13 or the like and rayon fiber filament yarn 14 or the like as corrosion material formed into a mesh. In this instance, the material is of being corrosive in three months or longer and twelve months or shorter, and a mesh structure is employed for avoiding mud escaping generated in a dehydration process and being in accordance with the growth of plants. Also, the yarn forming a bagging dehydration bag 10 is made into a mesh structure having a width of 1mm or more. Thus, a corrosion of a great part of the bag body makes an environmental pollution less, and further an interlocking effect causes it to be integrated with soil at the place of disposition. In this manner, any slippage is not likely to take place on the disposition surface, so that the ground can be rendered stably.

摘要： PROBLEM TO BE SOLVED: To prevent the breakage of a dehydrating bag and improve the dehydrating efficiency by interposing a water permeable layer between the water permeable dehydrating bag filled with the highly water-contained sludge accumulated in a river or lake and the ground arrangement surface. SOLUTION: To lay a dehydrating bag 1 having a water permeable bag body 11 filled with highly water-contained sludge 12, and a water permeable layer 3 having a flat upper surface is formed on the upper part of the arrangement surface 2 of the ground by use of sand layer, plastic board lane or nonwoven fabric. Thus, the collected load is generated on the lower side of the dehydrating bag 1 to prevent the breakage of the dehydrating bag 1, and the moisture of the sludge 12 within the dehydrating bag 1 is penetrated to the water permeable layer 3 through the lower side of the bag body 11, and effectively discharged to the outside. A recessed part conforming to the dehydrating bag 1 is formed on the upper surface of the water permeable layer 3, and the dehydrating bag 1 is fitted thereto and arranged, whereby the movement of the dehydrating bag 1 can be constrained, and the upper surface can be flattened after dehydration is ended.
