Abstract

The invention relates to the technical field of anti-floating anchor rod construction, in particular to a positioning controller for quickly placing an anti-floating anchor rod and a construction method of the anti-floating anchor rod. The positioning controller comprises an upper circular tube type positioner and a lower circular tube type positioner which are coaxially and vertically arranged, and further comprises a plurality of supporting legs, adjusting buckles and connecting rods, wherein the numbers of the supporting legs, adjusting buckles and connecting rods are identical; the supporting legs are rotationally connected to the outer side face of the upper positioner in a balanced mode, and the multiple adjusting buckles are slidably connected to the multiple supporting legs correspondingly; the upper ends of the connecting rods are rotationally connected to the outer side surface of the lower positioner in a balanced manner, and the lower ends are rotationally connected with the adjusting buckles respectively; the anchor rod installation comprises the steps of BIM modeling, anti-floating anchor rod construction point positioning, raft bottom concrete layer pouring, embedded pipe placing, cushion concrete layer pouring, drilling construction, grouting construction, anti-floating anchor rod placing, grout supplementing, acceptance inspection and cleaning; the anti-floating anchor rod is positioned through the upper positioner and the lower positioner, and the perpendicularity during anchoring is controlled; and BIM software is used for modeling, the position of the anti-floating anchor rod which interferes with raft bottom concrete reinforcing steel bars is changed, and accurate positioning is guaranteed.

Description

technical field [0001] The invention relates to the technical field of anti-floating anchor construction, in particular to a positioning controller for rapidly placing an anti-floating anchor and a construction method for an anti-floating anchor. Background technique [0002] In some large underground structures with shallow groundwater level, such as underground or open-air swimming pools, large basements, large underground caverns, etc.; Under the circumstances, the self-weight of the structure is not enough to resist the buoyancy of groundwater. At present, anti-floating anchors are often used to solve the increasingly prominent anti-floating problems of underground structures; anti-floating anchors are one of the anti-floating measures for underground structures in construction projects. Type, bearing tension, the force is also transmitted from the top of the pile to the bottom of the pile, and the magnitude of the force on the pile body changes with the change of the gr...
