COMPACTION PILE FOR HIGH BEARING FORCE CAST-IN-PLACE CONCRETE PILE AND THE LIKE AND CONNECTING TOOL THEREOF

摘要

PURPOSE: To attain light weight and low manufacturing cost by constituting a compaction pile jetting cement milk while rotating, out of a taper shaped outer cylinder which is provided with a hollow part, a nozzle, and an engaging groove, and a connecting tool (inner cylinder) which is provided with an injection hole in the center part. ;CONSTITUTION: A compaction pile 1 which is used for construction of a cast-in- place concrete pile and the like, and provided with a nozzle 6, a taper part 1a, etc., and further a hollow part inside, is manufactured by casting and the like. Meanwhile, a connecting tool 3 having an injection hole 4, a lengthwise projection 8, and the like is manufactured in particular, and fitted to the compaction pile 1 unrotatably. The compaction pile 1 is inserted into the hole of a cast-in-place concrete pile, cement milk is jetted from the nozzle 6 while rotating, and compaction is performed. Hereby, it is made in light weight and easily handled, and the manufacturing cost can be lowered.;COPYRIGHT: (C)1994,JPO
