Abstract: A press-in method includes a gripping step, a position measurement step of measuring a position of a pile in an objective coordinate system by a measurement management device disposed apart from a press-in machine, a command generation step of generating a command related to an operation of the press-in machine for moving the pile to a target position by using first position information of the pile in the objective coordinate system measured in the position measurement step and second position information on a position of the chuck in a subjective coordinate system based on an advancing direction of a saddle of the press-in machine, a positioning step of moving the pile to the target position, and a press-in step of pressing the pile into a ground.

Abstract: A manufacturing method of a concrete pile is shown. The method includes the following, that is, pouring concrete in the pile molding space, reducing the pile molding space to compress and mold the concrete, draining water drained from the concrete by compression and molding outside of the formwork from the drainage hole, and holding the concrete a predetermined amount of time to harden the concrete. The formwork includes an outer formwork that molds an outer wall surface of the concrete pile, an inner formwork that molds an inner wall surface of a hollow space of the concrete pile, and a pair of end formwork that mold upper and lower end surfaces of the concrete pile. The drainage hole is a gap between adjacent components when the mold is tightened, and the gap is configured to be capable of being opened larger during cleaning than when the mold is tightened.

Abstract: A pile press-in construction method uses a pile press-in device having a saddle, a clamp device grasping a top of an existing pile, a mast, a raising and lowering device, and a chuck device supported by the mast and holding a pile. The pile press-in device generates a reaction force by griping the existing pile with the clamp device, holds the pile by the chuck device, presses the pile into the ground by the raising and lowering device, and successively presses piles in while moving on a pile row including the existing pile to thereby extend the pile row. By turning of the mast and tilting of the chuck device about a chuck tilting axis, the chuck device is laid sideways and projects outward to a side of the pile row, the pile is supplied and inserted into the chuck device, and the chuck device grasps the pile.

Abstract: A charging box of a vehicle charging apparatus connects with a placement part provided on a carrier when a vehicle is carried by the carrier. The charging box then connects to a charging box receiving part provided on a storage with a movement of the vehicle from the carrier to the storage. The charging box is disconnected from the placement part after the connection of the charging box to the charging box receiving part.

Abstract: Provided are a pile press-in device and a pile press-in method that allow an efficient construction even when electrically powered devices and hydraulic devices coexist in order to give drive members a driving force. A pile press-in device (1) comprises a chuck (5) for gripping and rotating a pile (4) in order to press the pile (4) into a ground while rotating the pile (4). The pile press-in device (1) causes electric motors (6) corresponding to the electrically powered device of the invention to give the chuck (5) a driving force for the rotation. The chuck (5) is moved up and down by lift cylinders (7) which are hydraulically powered hydraulic devices. An integrated control board (50) controls the electric motors (6) and the lift cylinders (7) in an interlocked manner.

Abstract: A pile press-in machine that receives reaction force from an existing pile to press in a new pile, includes: a reaction force block that grips the existing pile by a clamp to receive the reaction force; a platform that is horizontally movable relative to the reaction force block; and a press-in block that is coupled to the platform, supported to be freely lifted up and down with respect to the platform at a front of the clamp, and grips and presses in the new pile, wherein a plurality of kinds of the reaction force blocks each according to a kind and size of the existing pile are freely attachable to and detachable from one platform.

Abstract: Provided are a pile joint, a pile coupling structure, and a pile coupling method that allow firm uniting of piles to be coupled. A joint (10) for coupling two piles (12) comprises: a tubular body (16) into which each pile (12) provided with a key (14) on a periphery thereof is inserted through an end (16A) of the body (16); and a fitting portion (22) formed on the body (16) so as to be fitted to the key (14) by the insertion and rotation of the pile (12). The fitting portion (22) is formed with: a tapered shape having a surface (22A) that is inclined so as to become distant from the end (16A) of the body (16) as the surface (22A) extends in the direction of rotation of the pile (12); or a wedge shape for fitting between a projection and a pile.

Abstract: A parking system includes an inventory status storage storing the status of inventory of a bicycle, two-wheeled vehicle, or car, and a control system that controls the status of inventory of the bicycle, two-wheeled vehicle, or car and controls check-in and check-out of the bicycle, two-wheeled vehicle, or car based on data stored in the inventory status storage. The parking system further includes a cooperative control unit for communicating with an external rental operator's server, converting instruction data on check-in and check-out transmitted from the server to commands processable for the control system, and instructing to do check-in and check-out.
