INTERLOCKED-EXCITER TYPE VIBRATION HAMMER AND PILING METHOD
PROBLEM TO BE SOLVED: To provide an interlocked-exciter type vibration hammer on which each exciter is rationally arranged.SOLUTION: An interlocked-exciter type vibration hammer V1 comprises two exciters 1A and 1B which are interlocked with each other, a base 3 on which the aforesaid exciters are fitted, and a chuck which is installed on the bottom face of the base 3. The two exciters 1A and 1B are positioned on the aforesaid base 3 in such a way that the distance (L) between the vibration-generating center lines c and c of the two respective exciters 1A and 1B is 1.5 to 2 times the distance (Y) between gravity centers G and G of the two respective semi-circular cross sections of a pile P which is split by a diameter D2 that is parallel to the vibration-generating center lines c and c.SELECTED DRAWING: Figure 2
【課題】起振機連動式バイブロハンマであって、各起振機の配置を合理的に設定可能とする。【解決手段】連動される２台の起振機１Ａ、１Ｂと、前記起振機を設置するベース３と、ベース３の下面に取り付けられたチャックとを有する起振機連動式バイブロハンマＶ１において、２台の起振機１Ａ、１Ｂが、２台の起振機１Ａ、１Ｂの起振中心線ｃ、ｃ間の距離（LＰＯ）が該起振中心線ｃ、ｃに平行な直径Ｄ２で分割された杭Ｐの２つの半円断面の各重心Ｇ、Ｇ間の距離（YＧＯ）の１．５〜２倍となるように、前記ベース３上に配置されている。【選択図】図２
