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： PROBLEM TO BE SOLVED: To remove cobble or the like by providing a branch pipe communicating with a muck recovery pipe at a position of an upper bent portion and also providing a clogging releasing weight in the branch pipe, which can be suspended and lowered to a muck intake portion at the muck recovery pipe. SOLUTION: When air is supplied from an air supply pipe 13 to a reverse pipe 10, a lifting current is created, muck from excavation work is flowed in from a muck intake 11 and an opening for a cross member 12 and is recovered above the ground. And if gravel or cobble is clogged at the muck intake 11 or the opening of the cross member 12, then a wire rope is extended and a clogging release rod 3 is lowered down to the lower end of a reverse pipe 10. Then, the clogging release rod 3 is lowered to the lower end of the reverse pipe 10. Then, the clogging release rod 3 pushes outwardly the muck clogged in the intake 11 at the tapered peripheral surface at the tip and also pushes out the muck clogged in the opening of the cross member 12 at the tip face. If the clogging cannot be released by the above operation, the rod 3 is slightly raised and the tension in the wire rope is released and the clogging release rod 3 is dropped by a free falling. By doing this, gravel or the like can be easily removed.
