Inner tamping immersed tube cast-in-place pile head and inner tamping immersed tube cast-in-place pile
The invention relates to the technical field of cast-in-place piles, in particular to an inner tamping immersed tube cast-in-place pile head. The inner tamping immersed tube cast-in-place pile head comprises a connecting part and a pile head body, the pile head body is in an inverted cone shape, the upper portion of the pile head body is connected with the lower portion of the connecting part, a rotating shaft is arranged in the circumferential direction of the connecting part, the pile head body is defined by a plurality of pile head plates, and each pile head plate is connected with the rotating shaft and can rotate around the rotating shaft. During use, the pile head is detachably connected to the lower portion of an outer pipe, and when the outer pipe and an inner pipe sink downwards,the pile head body is in a folded and closed state under the action of the structure of the pile head body and soil pressure, so that the effects of water resistance and mud resistance are achieved; and the outer pipe is lifted upwards, and the pile head body is in an open state under the action of concrete pressure in the outer pipe, so that concrete falls into a pile hole to form a pile. Therefore, the inner tamping immersed tube cast-in-place pile head and the inner tamping immersed tube cast-in-place pile are simple in structure and good in water and mud blocking effect, the pile head canbe recycled, and waste is avoided.
本发明公开涉及灌注桩技术领域，尤其涉及一种内夯沉管灌注桩桩头，其包括连接部、桩头体，桩头体的形状为倒锥形，桩头体的上部与连接部的下部相连接，连接部的周向上设置有转轴，桩头体由多块桩头板围合而成，每块桩头板与转轴相连接，且桩头板可绕转轴旋转。使用时，将该桩头可拆卸连接设置在外管的下部，外管、内管向下沉管时，在桩头体自身结构和土压力的作用，桩头体处于收拢闭合状态，起到阻水阻泥的效果；向上提外管，在外管内混凝土压力作用下，桩头体处于张开状态，使混凝土落入桩孔中并成桩。可见，本发明的内夯沉管灌注桩桩头和内夯沉管灌注桩的结构简单，阻水阻泥效果好，桩头可以回收重复使用，不会造成浪费。
