Large-diameter high-strength special stabilized steel bar anchoring connection method foundation pile uplift construction method

Abstract

The invention discloses a large-diameter high-strength special stabilized steel bar anchoring connection method foundation pile uplift construction method, and relates to the technical field of upliftpiles. According to the method, positioning pins, steel plates, an uplift pile, main rib frames, through holes, a base and a foundation pit are involved, the foundation pit is formed in the upper surface of the base, the uplift pile is arranged in the foundation pit, the main rib frames are fixedly embedded in the uplift pile, the top ends of the main rib frames penetrate through the uplift pileand extend to the upper portion of the uplift pile, the two steel plates are placed at the upper portion of the uplift pile, the two corresponding sets of through holes are formed in the upper surfaceof each steel plate, each of the top ends of the main rib frames sequentially penetrate through the two corresponding through holes and extends to the upper portion of the through holes, and the positioning pins are fixedly connected to the outer surfaces of the main rib frames correspondingly. The large-diameter high-strength special stabilized steel bar anchoring connection method foundation pile uplift construction method has the advantages that an uplift pile head does not need to be broken, and testing can be directly carried out, and solves the problem that the broken uplift pile is inaccurate in testing.

Description

technical field [0001] The invention relates to the technical field of uplift piles, in particular to a large-diameter high-strength special stabilized steel bar anchor connection method for foundation pile uplift construction methods. Background technique [0002] Pull-out piles are widely used in anti-floating of large basements, pull-out resistance of high-rise buildings, pull-out resistance of offshore wharf platforms, anchor pile foundations of suspension bridges and cable-stayed bridges, pile foundations of large dock floors and anchor pile foundations in static load test piles, etc. , refers to the piles that are driven in order to offset the buoyancy of the structure caused by the water in the soil when the underground structure of the construction project is lower than the surrounding soil water level. The main mechanism of the uplift pile is to rely on the pile body and the soil layer frictional force to resist axial tension, such as anchor piles and anti-floating ...
