Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to an installation and positioning device for pile foundation construction. Background Art

[0002] Pile foundation construction is a process in which a columnar pile body is made of reinforced concrete, steel, wood, etc., and then driven or pressed into the stratum until solid soil is formed by a pile sinking machine, or a hole is first formed and then cast into a concrete columnar pile body, thereby strengthening the bearing capacity of the pile cap. In the construction method of first forming a hole and then casting into a concrete columnar pile body, in order to further enhance the strength of the pile foundation, a steel cage or a steel support is installed inside the pile foundation, and finally concrete is poured into the pile foundation. In the process of installing the steel support to the pile foundation, the installation position of the steel support cannot have a large deviation. In the process of inserting the steel support into the inner cavity of the pile foundation, if an angle deviation occurs, not only the steel support cannot be smoothly installed in the pile foundation, but also the overall strength of the pile foundation will be weaker than the expected strength after the installation is completed. Since the existing installation of the steel support is usually carried out by lifting the steel support with a crane, and assisting the installation by manually stabilizing the steel support, this installation method is not only prone to installation angle deviation, but also has construction safety hazards. For this reason, a person skilled in the art proposes an installation and positioning device for pile foundation construction. Utility Model Content
