摘要： PURPOSE:To prevent the liquefaction of foundation ground by avoiding the generation of excessive void water pressures at the time of earthquake by driving a given number of drain pillars consisting of a reinforced water-permeable concrete pipe and a water-permeable wall into the foundation ground. CONSTITUTION:In a foundation ground B to support a structure A on the earth's surface, pits 11 are drilled in given places surround foundation piles 4 and then water-permeable concrete pipes 1 reinforced with iron bars 5 are set. Then, water-permeable wall-forming materials 12, e.g., gravel, fine stones, slags, etc., are charged into the apertures between the reinforced water-permeable concrete pipes 1 and the pits 11 to form a water-permeable wall 2 in order to build drain pillars 3. By this, excessive void water pressures to be generated at the time of earthquake are dissipated into the foundation ground B and the liquefaction of the foundation ground B and the surrounding ground of the foundation piles 4 can be prevented.

摘要： PURPOSE:To surely chuck the main reinforcing bar by setting the engaging plate provided with plural engaging holes and the chucking plate provided with plural gourd type engaging holes on the same axis, revolting one of the engaging plate or the chucking plate and engaging the end part of the main reinforcing bar which is inserted through the small hole part. CONSTITUTION:By rotating, at least, one of the engaging plate 4 or the chucking plate 5, the end part of the main reinforcing bar 6 which is inserted through the engaging hole 2 and the gourd type engaging hole 4a is engaged. In the state that the end part of the main reinforcing bar 6 is inserted through the engaging hole 2 and the larger hole part 4b of the gourd type engaging hole 4, one of the engaging plate 3 or the chucking plate 5 is rotated. The chucking is exactly executed at the right position i.e., the small hole part 4a by positioning the main reinforcing bar which is inserted through the engaging hole 2 and the larger hole part 4b of the gourd type engaging hole 4 to the small diameter part 4a. And because the pushing means to push the main reinforcing bar is provided at the position corresponded to the respective engaging hole 2 and the gourd type engaging hole 4 of the end surface of the knitting machine body, so the inserting of the main reinforcing bar is also automatized.

摘要： PURPOSE:To reduce the wall thickness of a cylindrical retaining mold and to prevent the damage of said mold by inserting the cylindrical retaining mold filled with concrete not hardened in a rotary casing and imparting rotation to the rotary casing by a centrifugal apparatus in such a state that the cylindrical retaining mold is held concentrically with respect to the rotary casing by the holding jigs provided to the peripheral wall of the rotary casing to perform centrifugal molding. CONSTITUTION:A cylindrical retaining mold 3 filled with concrete not hardened is inserted in the rotary casing 2 placed on a centrifugal apparatus 1 to be held in concentric relation to the rotary casing 2 by holding jigs 4 and, in this state, rotation is imparted to the rotary casing 2 by the centrifugal apparatus 1. By this method, the cylindrical retaining mold 3 is rotated and the concrete not hardened received in the cylindrical retaining mold 3 is centrifugally molded to mold a concrete pipe. When a vibration apparatus 5 is connected to the end part of the cylindrical retaining mold 3 or to the end part of the rotary casing 2 and the concrete pipe is centrifugally molded while weak vibration is given to the cylindrical retaining mold 3, the concrete pipe enhanced in compactness and having high strength can be prepared even from low slump concrete not hardened reduced in the use amount of water per a unit volume.

摘要： PURPOSE:To make work so easily by holding a storage ring unit provided with a locating frame supporting this storage ring rotatably on an outer circumferential part of the storage ring with a part, winding a long material in coil form and housing it, on a holding device installed separately in a plant line. CONSTITUTION:A storage ring unit A is mounted on a holding device H and held thereon after aligning a peripheral locating member 9 to a holding part Ha of this holding device H. In this case, a turning shaft J is also inserted into a turning shaft hole 2 existing in the central part of a storage ring L. Then, a starting end of steel bar P or the like is drawn in an inner part of the storage ring L by way of a guide roller, and inserted into a set hole of a barrel ring 1 and engaged in it. In this stage, an engaged pin 5 is extracted, and when a drive motor M is driven and the turning shaft J is rotated, only the storage ring L is rotated, starting its winding. If a specified amount of it is wound up, the pin 5 is inserted thereinto, and relative rotation between a frame F and the ring L is stopped. Afterward, this storage ring unit A is set to the holding device H at another plant and delivered.

摘要： PURPOSE:To intend simplified working processes and shortened working periods by providing an auger shaft with a multiple step of hydraulic-operating dia. enlarging devices whose pitches are adapted to the pitches of knot-attached core materials and forming the enlarged dia. portions of respective steps simultaneously. CONSTITUTION:A multiple step of dia. enlarging devices 2 with hydraulic- operating dia. enlarging edges 7 are installed in an axial direction of an auger shaft 1. Then, the pitches of the dia. enlarging devices 2 are adapted to the pitches of the knots of knot-attached core materials. So, when the ground is bored or after it is bored up to a preset depth, the dia. enlarging devices 2 are enlarged in dia. to form enlarged dia. portions on a hole wall simultaneously in respective steps. Then, an outside lacing 6 is provided with an opening 8 for the entry of the dia. enlarging 7 in and out to form a case auger 9 for boring. It is thus possible to rationalize boring work for an enlarged-dia. hole.

摘要： PURPOSE:To enable loading of concrete and closing with a lid body easily, by a method wherein the lid body whose inside is formed in a circular arc surface continuing to the inside of a concrete form is provided on a slitlike opening extending to the longitudinal direction of a long concrete form body whose section is made in a generally C-shaped form. CONSTITUTION:A concrete form 1 is generally cylindrical and provided with a lid body 1b which is fitted openably-and-closably to a slitlike opening 4 extending to a longitudinal direction of a long-sized concrete form body 1a whose section is made in a generally C-shaped form. The undersurface of the lid body 1b is of a circular arc surface 6 continuing to the inside of the concrete form body 1a. As the concrete form 1 is thus constructed, when concrete 2 is loaded into the concrete form body 1a which is generally a cylinder by turning the slitlike opening 4 up, it is unnecessary to heap up the concrete 2 even if volume of the concrete 2 is much, permitting easy loading of concrete. Moreover, since the concrete 2 is hardly stuck to a part to which the lid body 4 is fitted, closing with the lid body 4 can be performed easily.

摘要： PURPOSE:To prevent the liquefaction of the ground by dissipating void water quickly rising during the earthquake by a method in which a draining material is packed around a knotted pile as a core material to form a foundation pile, and a water communication means is vertically led to the knots of the pile. CONSTITUTION:A drain material 2, e.g., gravels, etc., is packed around a custom-made knotted pile 1 as a core material to form a foundation pile in the ground which is liable of liquefaction. A vertical through hole 6 as a means of connecting the walls of upper and lower drain materials 4. Since the drain materials 2 so formed are vertically connected with each other through the hole 6, void water ready to quickly rise during the earthquake is exactly dissipated through the portion of the drain materials 2 to prevent the occurrence of excess void water pressures responsible mainly for the liquefaction of the ground.
