The invention discloses a novel pile head cutting, positioning and breaking method. The novel pile head cutting, positioning and breaking method comprises a pile casing, an annular supporting block and a plurality of connecting blocks, wherein a reinforcement cage is arranged inside the pile casing, a limiting groove is formed in the bottom of the annular supporting block, the limiting groove abuts against the upper end of the pile casing, a plurality of locking rods are rotationally connected to the inner wall of the limiting groove in a threaded mode, And one ends of the multiple locking rods penetrate through the outer portion of the annular supporting block, the other ends of the multiple locking rods are rotationally connected with abutting blocks through bearings, the upper ends of the multiple abutting blocks abut against the inner top of the limiting groove, and the multiple abutting blocks are symmetrically arranged. The method has the advantages that by reserving the right-angle opening of the cut-off ring, rapid breaking can be achieved during pile head breaking, compared with a traditional chiseling method, the speed is higher, the efficiency is higher, and by means of the horizontal pre-splitting benefit of the right-angle rabbet of the cut-off ring, the broken cross section of the pile head can be smoother and controllable compared with a traditional breaking method.
Description
technical field [0001] The invention relates to the technical field of construction, in particular to a novel pile head cutting and positioning removal method. Background technique [0002] In the construction industry, the foundation pile is an essential part, and the foundation pile is a vertical or inclined foundation component set in the soil, its function is to pass through the weak and highly compressible soil layer or water, The load is transmitted to the harder, denser or less compressible foundation bearing layer, and during the construction of the mechanical hole-forming pile foundation, the excess pile head at the upper end of the foundation pile is generally removed; [0003] The traditional method of removing pile heads has always been to remove from the pouring surface from top to bottom to the design pile top elevation. Due to the uneven level of construction personnel, it is difficult to meet the flatness requirements of pile heads. In addition, due to Due t...
