Description

Technical Field

[0001] The utility model belongs to the field of building construction, and particularly relates to a verticality measuring device for installing an extra-long steel pipe pile. Background Art

[0002] Most of the existing high pier cap beam supports use structurally stable steel pipe pile supports, and for safety reasons, they are installed in multiple sections, and the verticality of each section needs to be strictly controlled. When the height of the high pier cap beam support is low, a plumb line can be used; when the height of the high pier cap beam support is high, surveyors need to use measuring instruments for observation, and the instruments cannot be removed during the installation of the steel pipe piles. It is necessary to continuously measure and adjust the verticality during the installation process, and then fix the steel pipe piles until the welding is completed. When measuring with the help of measuring instruments, it takes up the time of surveyors and measuring instruments, affects construction efficiency, and has certain safety risks.
