摘要： PURPOSE:To make demolding of a pile easy, by a method wherein semi- cylindrical half bodies of a concrete form are formed into a cylinder and node molding recessed parts provided at positions where nodes are formed comprise movable and elastic parts of rubbery plastic material in a longitudinal direction of the half bodies of the concrete form. CONSTITUTION:A manufacturing concrete form 1 is generally cylindrical, and comprises top and bottom two half bodies 1a, 1b which are obtained by dividing the concrete form into two parts in a circumferential direction. Rubbery elastic parts 10 are provided in the half bodies 1a, 1b of the concrete form extending over the circumferential direction and at equal intervals in the longitudinal direction. Node molding recessed parts 6 are provided in the elastic parts 10 and nodes of a PC pile 11 are formed by the knot molding recessed parts 6. The PC pile 11 is demolded by lifting the same in the inside of the half body 1b of the concrete form after removing the half body 1a of the concrete form. In this time, even if the PC pile 11 contracts, the node come off easily due to elastic deformation of the elastic parts 10 and demolding is performed smoothly.

摘要： PURPOSE:To enable easily loading of concrete and taking out a pile out after molding, by dividing a cylindrical concrete form into three parts in a circumferential direction. CONSTITUTION:A concrete form 1 is generally cylindrical and formed of concrete forms 1a, 1b, and 1c obtained by dividing the concrete form 1 into three parts in a circumferential direction. At the time of molding of a pile 15, the two divided concrete forms 1b, 1c are set up on an assembling stand 16 under while the remaining concrete form 1a is removed, an iron rod cage 7 for reinforcement is set up within the divided concrete forms 1b, 1c and concrete 2 is loaded through an upper opening by dropping the concrete 2 from a loading machine 17 under this state. At this time, as the divided concrete forms 1b, 1c are raised upward than a semi-circular state, the concrete 2 is filled sufficiently in the divided concrete forms 1b, 1c and hard to overflow. At the time of taking out the pile 15, as the concrete form is disassembled into the concrete forms 1a, 1b, 1c, the pile 15 can be taking out easily.

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 water-permeable concrete pipes and water-permeable walls into the foundation ground. CONSTITUTION:In a foundation ground B supporting a structure A on the earth surface, pits 11 are drilled in given places surrounding the foundation piles 4 and the then water-permeable concrete pipes 1 are set. Then, water-permeable wall- forming materials 12, e.g., gravel, fine stones, slags, etc., are charged into the apertures between the 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 prevent the sand ground under foundation piles and a footing from liquefaction as well as to seek the security of bearing force by a method wherein drain piles composed of a good permeable material such as pebbles, fine stones, sludge, etc. are driven into the ground around the foundation piles. CONSTITUTION:Drain piles 5 are arranged in a proper interval and driven in the ground along almost the all circumference of an outer peripheral wall side of a footing to be constructed at the upper part of a foundation pile 1. In the formation of the drain pile 5, a casing 10 wherein a cover 11 freely opening and closing which closes during a driving in and opens during the pulling out in suspending with its own weight is equipped at the point part is driven into a given place of the ground by means of a vibration generator 12 such as a vibrohammer, etc. After a given length of the casing is driven into the ground, while the materials for formation of a drain pile such as pebbels, fine stones, sludge, metals and synthetic resin particle on pieces are being cast into the casing 10, the casing 10 is pulled out to form the drain pile 5 in the ground.

摘要： PURPOSE:To set reinforcements at prescribed positions by enclosing the outer peripheries of ring parts with guide members leaving a small clearance and fitting and setting the end parts of supplied reinforcements into kerfs equipped on the outer peripheral surfaces of the ring parts in rotation of the ring parts. CONSTITUTION:A freely rotatable ring parts 2 are provided at one side end part of a knitting machine body 1 and the outer peripheries of the ring parts 2 are enclosed with the guide members 3 leaving a small clearance. The end parts of the reinforcements 5 supplied from supply holes 4 of the guide members 3 are fitted and set into the kerfs 6 mode on the outer peripheral surfaces of the ring parts 2. The reinforcements 5 fit and set into the kerfs 6 are moved in the axial direction of the knitting machine body 1 and projected to the other part of the weaving machine body 1 through hole parts 8 equipped in the knitting machine body 1. Thus, irrespective of change of the diameter and pitch of the reinforcement, the reinforcements can be set at prescribed positions of the knitting machine body can be set easily and automatically to efficiently and economically from a reinforced basket.

摘要： PURPOSE:To automate a feeding operation by installing a delivery part in a part of the circumference of a storage case, while setting up a rotary ring, housing a coil-form steel bar, in an inner part of the storage case free of vertical movement and rotation, and opposing an uplifted part at a lower part of the rotary ring to a lower opening. CONSTITUTION:A storage case 1, where a coil-form steel bar 2 is wound on an internal rotary ring 4 and housed, slides on a support base 23 of a supporter 7 from a carry-in passage 20 and is situated in a specified position of a device 7. Next, a cylinder 36 operates whereby a guide roller 34 stands erect and is positioned in response to an opening 18 of the case 1. In addition, a lifting cylinder 38 is operated, making a lifting block 26 of a lifting rotational means 8 go up, and an uplifted part 5 at an underside part of the ring 4 is uplifted by a rotary table 27. When, a drive motor 28 is driven, turning the table 27 and the ring 4 either, and the steel bar 2 is delivered to a pinch roller 32 from a delivery part 3, and it is delivered to a next process 33 by this roller 32.

摘要： PURPOSE:To improve the method of load testing by shortening the period of testing by a method in which a push-up force is applied to the outer tube and also a push-down force is applied to the inner tube by means of the loader of a loading tube in which the inner tube whose lower part is projected toward the lower part of the outer tube is made movable in the outer tube. CONSTITUTION:A loading tube 3, in which an inner tube 2 whose large-diameter lower part 8, having the same diameter as that of an outer tube 1, is inserted into the outer tube 1 by a detachable inner tube temporary holder 10, is penetrated to a given depth into the ground 4. The holding of the inner tube 2 by the holder 10 is released, and a push-up force is applied upwardly to the outer tube 1 and a reaction (push-down force) is applied to the inner tube 2 by a loader 5 attached by welding to the upper end of the outer tube 1. The moving amounts of the tubes 1 and 2 are separately measured by displacement meters 28 and 35. The constitution of the apparatus can be simplified, the testing period can be shortened, the cost of testing can be reduced, and also the designing of pile can be economized.
