Rock-socketed pile post-grouting pile head structure and construction process thereof
The invention relates to a rock-socketed pile post-grouting pile head structure and a construction process thereof. The pile head structure comprises a pile hole, wherein a pile body is arranged in the pile hole; an over-grouting area is arranged below the pile top of the pile body; an empty pile treatment area is arranged between the pile top of the pile body and the ground; the pile body comprises a plurality of pile longitudinal ribs which are annularly arranged; spiral stirrups are arranged on the pile longitudinal ribs in the over-grouting area; a left grouting pipe and a right grouting pipe are arranged on the spiral stirrups; a plurality of additional fixing stirrups are arranged on the pile longitudinal ribs in the empty pile treatment area at intervals up and down; the left grouting pipe and the right grouting pipe are connected with the additional fixing stirrups; first concrete is poured in the over-grouting area; and second concrete is poured in the empty pile treatment area. According to the rock-socketed pile post-grouting pile head structure and the construction process thereof, the problems that the rock-socketed pile post-grouting construction difficulty is large, the construction efficiency is low, and the construction effect is poor in a karst area can be solved.
本发明涉及一种嵌岩桩后注浆桩头结构及其施工工艺，所述桩头结构包括桩孔，所述桩孔内设置有桩身，所述桩身的桩顶以下为超灌区域，所述桩身的桩顶与地面之间为空桩处理区，所述桩身包括呈环形布置的多个桩纵筋，多个桩纵筋上在超灌区域设置有螺旋箍筋，所述螺旋箍筋上设置有左右两个注浆管，多个桩纵筋在空桩处理区上下间隔设置有多个附加固定箍筋，左右两个注浆管与多个附加固定箍筋相连接，所述超灌区域浇筑有第一混凝土，所述空桩处理区浇筑有第二混凝土。本发明一种嵌岩桩后注浆桩头结构及其施工工艺，它可以解决岩溶地区嵌岩桩后注浆施工难度大，施工效率低，施工效果差的问题。
