    • A new section coupling is for use by vibratory, oscillatory and rotatory driving in bored pile construction. It includes adapted ends with inclined surfaces and a bolting system comprising in male section (2) a row of features with reduced thickness (22) and bolt holes (11) (18) and in the female section (1) a row of holes (31) to match for tightening. A set of male supports (7) and female supports (5) are adapted for fitting into the features of reduced thickness and filling the holes (31). All the bolts have counter threads and an overhang at bolt heads for adaptation of a locking device attached to it; all the bolts are restrained by keying the locking device with a spring feature and the overhang. A tool is used to press and un-press the spring features to lock and unlock the bolt. The good fit at interfaces allow transferring of longitudinal force without an elastomeric isolator at interface.
    • 一个新的部分联接是通过振动,振荡和旋转驱动在钻孔桩施工中使用的。 其包括具有倾斜表面的适配端部和螺栓系统,该螺栓系统包括在阳部分(2)中的一排具有减小的厚度(22)和螺栓孔(11)(18)的特征,并且在阴部分(1)中具有一排孔 31)匹配收紧。 一组阳性支撑件(7)和阴型支撑件(5)适于装配成减小厚度的特征并填充孔(31)。 所有的螺栓都具有相对螺纹和螺栓头上的悬垂,用于适应附接到其上的锁定装置; 所有的螺栓通过用弹簧特征和突出部分锁定锁定装置来限制。 一个工具用于按压和取消按压弹簧特征来锁定和解锁螺栓。 界面上的良好配合允许在接口处没有弹性隔离器传递纵向力。
