A Pile Head Cutting and Locating Breaking Method

Abstract

The invention discloses a pile head truncation positioning breaking method, which comprises a casing, an annular support block and a plurality of connection blocks, a reinforcement cage is arranged inside the casing, and a limiting groove is provided at the bottom of the annular support block, so that The limit groove is in contact with the upper end of the casing, and the inner wall of the limit groove is threadedly connected with a plurality of locking rods, and one end of the plurality of locking rods penetrates to the outside of the annular support block. The other ends of the locking rods are rotatably connected with abutment blocks through bearings, and the upper ends of the plurality of abutment blocks all abut against the inner tops of the limiting grooves, and the plurality of abutment blocks are arranged symmetrically. The advantages are: by reserving the right-angle opening of the truncated circle, rapid breaking can be achieved when breaking the pile head, which is faster and more efficient than the traditional chiseling method, and the horizontal pre-splitting benefit is achieved through the right-angled groove of the truncated circle , which can make the truncated section of the pile head more smooth and controllable than the traditional breaking method.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a method for truncation, positioning and breaking of pile heads. Background technique [0002] In the construction industry, the foundation pile is an indispensable part, and the foundation pile is a vertical or inclined foundation member set in the soil. The load is transferred to the harder, denser or less compressible foundation bearing layer, and during the construction of the mechanically bored pile foundation, the excess pile head at the upper end of the foundation pile is generally removed; [0003] The traditional method of breaking the pile head has always been to break from the top to the bottom of the pouring surface to the design pile top elevation. Due to the uneven level of the construction workers, it is difficult to achieve the flatness requirements of the pile head chiseling. The characteristics of concrete materials, when chiseling to the design elevation,...
