(57) Abstract Objective In case of the housebreaking job of the bar for ground additional strength, groundThe coming out falling of the bar from in is prevented. Constitution On guide component 2 of time dynamic possible long shaku the longitudinal oneThe forward/backward moving to direction on straight advancing component 3 where possibly it is installed the vibrating machineThe bar pushing for ground additional strength where structure 6 and bar grip feature 8 is loadedIn the being packed machine, being locked by guide component 2, bar B the InterpolationIn the bar guide 20 who is done catching the convex provision B1 of bar BTo obstruct the converse Shank operation of te bar B and propulsion operation of bar B permissionPermitting/inserting the nonreturn pawl 21 which is done, the contact breaker points where nonreturn pawl 21 touches to bar BBeing laid out in the diagonal rear of b, bar propulsion direction the axis which crossesRock operation possibly axial support it does as a rock center a.
