Multifunctional measurement and control pile with stable structure and construction method thereof

Abstract

The invention discloses a multifunctional measurement and control pile with a stable structure and a construction method thereof. The multifunctional measurement and control pile comprises a plurality of cast-in-place piles, a bearing platform, a containing pipe, a plurality of inclined struts, a forced centering disc and a placement base, wherein the cast-in-place piles are used for supporting a bottom plate of a foundation pit and are buried in the foundation pit; the bearing platform is cast at the upper end of one cast-in-place pile, and vertical steel bars of the cast-in-place piles are anchored in the bearing platform; the containing pipe is vertically arranged on the bearing platform, the upper end of the containing pipe extends to the position above the bottom plate, and concrete is poured into the containing pipe; the inclined struts are connected between the two opposite sides of the containing pipe and the other cast-in-place piles, and the inclined struts are arranged in a central symmetry mode with the containing pipe as the symmetry center; the forced centering disc is used for erecting a total station and is buried in the concrete at the upper end of the containing pipe; and the placement base is used for installing the total station and is connected to the outer portion of the upper end of the containing pipe. According to the multifunctional measurement and control pile with the stable structure and the construction method thereof, the problems that the construction efficiency is low and the lofting positioning precision is low due to the fact that precise lofting control of embedded parts with high installation precision requirements in the bottom plate adopts a traditional forced centering observation platform outside the foundation pit are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a structurally stable multifunctional measurement and control pile and a construction method thereof. Background technique [0002] According to the installation requirements of the underwater vibrating table process equipment, 56 groups of embedded parts for group actuators are installed in the ultra-thick base plate of the underwater vibrating table (the thickness of the base plate is 5m), which provides sufficient support and reaction force for the vibrating table process equipment . Moreover, the installation accuracy of the bolt rod of the embedded part of the group actuator is extremely high, specifically: the plane positioning error of the bolt rod is ±2mm, and the elevation error is ±2mm. [0003] In addition, with the gradual advancement of the construction of the ultra-thick foundation floor of the underwater shaking table, the core area where the embedde...
