Large-diameter cast-in-situ bored pile and construction method thereof
The invention discloses a large-diameter cast-in-situ bored pile. The pile comprises a column body and a bottom. The ground of the bottom further comprises two concentrically-arranged annular protruding strips. After a cylindrical cage and an annular cage are connected into a whole, concrete is poured into the cages, and then the cages are coagulated and formed. Five grouting pipes are connected with the outer side of the cylindrical cage and connected with a grouting machine. According to the large-diameter cast-in-situ bored pile and the construction method thereof, the method is wide in applicability, high in construction speed, and reliable in quality; adverse effects of hole bottom sediment can be eliminated; and the pressure bearing area of the end of the pile constructed through themethod is increased, and the bearing capacity of the end of the pile is improved.
本发明公开了一种大直径钻孔灌注桩，包括柱体和底部，底部的地面还包括两条同心设置的环形凸条；其整体由柱形笼和环形笼连接成一体之后，灌注混凝土后凝结成型；所述柱形笼的外侧连接有五根注浆管，所述注浆管连接有注浆机械。本发明一种大直径钻孔灌注桩及其施工方法，该方法适用性广、施工速度快、质量可靠，能消除孔底沉渣的不良影响，通过该方法制作的大直径钻孔灌注桩，提高了桩端的承压面积，提高了钻孔灌注桩的桩端承载力。
