Verticality adjustment system for lattice column correcting mount and construction method thereof

Abstract

The invention relates to the technical field of constructional engineering, in particular to a verticality adjustment system for a lattice column correcting mount and a construction method thereof. In the method, the verticality adjustment system for the correcting mount, a spacer, a correcting mount placement method and a correcting method for lower placement of the lattice column are adopted. The verticality adjustment system is characterized in that the lattice column is positioned for free hanging; the placement method for the spacer and the correcting mount is as follows: through the natural terrace position line, the X direction and the Y direction are aligned and leveled to the water level; and the correcting method for lower placement of the lattice column is as follows: when the lattice column is hanged to a marked elevation, the lattice column is free hanging by utilizing the correcting system, and the purpose for controlling the lattice column verticality is achieved. Through the special innovation for the construction method of the verticality adjustment of the lattice column with ultra-deep foundation and the special design for the verticality adjustment system for the lattice column correcting mount, only the construction technology of a normal column pile is adjusted, so that the lattice column can satisfy the verticality control requirement in ultra-deep foundation, necessary construction conditions are provided for the subsequent construction, and the resource expenditure and construction cost of the column pile and the subsequent construction are greatly reduced.

Description

technical field [0001] The invention relates to an ultra-deep foundation pit lattice column correction frame vertical adjustment system and a lattice column correction vertical adjustment construction method, belonging to the technical field of construction engineering. Background technique [0002] Column-to-column-to-pillar is an effective method for upside-down construction of basement as a vertical temporary bearing. Among them, the pile body can be a bored pile, and the column generally adopts a steel member, and usually a combined column with a steel cage and a lattice column at the top can be used. At present, as the reverse construction basement is getting deeper and deeper, the design bearing capacity of the steel column is greatly increased, and the cross section of the steel lattice column is also greatly increased. At the same time, as the main bearing member of the reverse construction slab, the main beam When the column passes through, the steel bar needs to p...
