摘要： PROBLEM TO BE SOLVED: To pile even into complicated ground by constituting a pile driving equipment with a hammer device, broken pieces discharge pipe provided in a steel pipe and a weight rising and falling along the discharge pipe and by erecting the hammer device, a drive source, a lifting device for the weight, a supporting portion for the discharge pipe, and the related equipment at the upper portion of the steel pipe in one united body. SOLUTION: An impact device provided with a hammer 1 at the upper end of the pipe 2 is installed at the upper end of the steel pipe 2, and internally a broken piece discharge pipe 3 is arranged vertically. The lower end of the discharge pipe 3 is opened inside the steel pipe 2, the other end is provided outside the steel pipe 2, and broken pieces occurred inside the steel pipe 2 are discharged to the outside from a passage of compressed air provided along the discharge pipe 3 together with circulating water 4. Inside the penetration hole 51 opened in the vertical direction at the center of the steel pipe 2, a weight 5 penetrating the discharge pipe 3 is provided, the weight 5 is lifted and lowered along the discharge pipe 3 by winding and unwinding of a weight wire W2 fixed to the weight 5, and ground and boulders inside the steel pipe 2 are crushed by this impact force. Since the crushing inside the steel pipe 2 can be performed in parallel to the impact of the hammer, 1, responses to the diversified changes in ground can be performed.

摘要： PURPOSE:To enlage timbering work as well as make transportation easier by a method in which a large-scale timbering is floated and towed to a given position and hung up to a given level, a small timbering is assembled on the large-scale timbering, and concrete is placed. CONSTITUTION:A large-scale timbering 11 whose buoyancy can be adjusted by supply or discharge of water is floated and towed to a given position between piles. The timbering 11 is hung up to a given level and fixed to the hang metal 50 of pile head by a hanging bar 51, and a small timbering 12 and a ladder-type timbering are attached to the upside of the timbering 1 to assemble a formwork timbering. A formwork is temporarily fixed to the upside of the formwork-receiving timbering and concrete is placed. The timbering can thus be enlarged and easily transported.
