Pile head cutting-free type cast-in-situ bored pile construction device and construction method thereof
The invention relates to the technical field of cast-in-situ bored pile construction, in particular to a pile-head-cutting-free cast-in-situ bored pile construction device which comprises an outer sleeve and an inner isolation plate, a guide pipe through hole penetrates through the center of the inner isolation plate, and a main reinforcement through hole penetrates through the part, close to the edge of the inner isolation plate, of the inner isolation plate. Two sliding openings are formed in the inner side wall of the guide pipe passing hole, sealing blocks are arranged in the sliding openings in a sliding mode respectively, a plurality of guide holes are formed in the inner isolation plate, the guide holes are communicated with the sliding openings, and feeding assemblies used for promoting the sealing blocks to move towards the center position of the inner isolation plate are arranged in the guide holes. According to the cast-in-situ bored pile, the inner isolation plate has a limiting effect so as to guarantee the pouring height of concrete, meanwhile, the two sealing blocks clamped on the outer side wall of the guide pipe also have a limiting effect, the amount of the concrete overflowing through the guide pipe passing hole is reduced, the effect of avoiding breaking the pile head of the cast-in-situ bored pile is achieved, and the construction efficiency of the cast-in-situ bored pile is improved.
本申请涉及钻孔灌注桩施工的技术领域，尤其是涉及一种免截桩头型钻孔灌注桩施工装置，包括外套管和内隔离板，内隔离板的中心位置贯通有导管通过孔，内隔离板靠近其边沿的部分贯通有主筋通过孔，导管通过孔的内侧壁上开有滑移口，滑移口开有两个，滑移口内分别滑移有密封块，内隔离板上开有若干个导向孔，导向孔与滑移口相通，导向孔内设有用于促使密封块朝向所述内隔离板中心位置移动的进给组件。本申请中的内隔离板具有限制作用，以保证混凝土的浇灌高度，同时两个夹在导管外侧壁的密封块也具有限制作用，减少了混凝土通过导管通过孔溢出的量，以此实现了免破除钻孔灌注桩桩头的效果，提高了钻孔灌注桩的施工效率。
