Abstract

The invention relates to a reinforcing steel bar sleeve-free type soil anchor rod anchor head. The reinforcing steel bar sleeve-free type soil anchor rod anchor head comprises a barrel-shaped anchor rod wall defined by a plurality of sets of reinforcing steel bars (1) which are arranged at equal intervals and in a spaced manner, a bottom plate (3) is arranged at the bottom of the anchor rod wall,a top plate (4) is arranged at the top of the anchor rod wall, the lower portion of the anchor rod wall is bent to be a cone-shaped body, and the middle portion of the top plate (4) is provided with finishing rolled deformed steel bars (2). The single soil anchor rod ultimate pulling resistance is greater than that of an existing anti-floating pile; and the reinforcing steel bar sleeve-free type soil anchor rod anchor head is convenient to construct and relatively economical.

Description

technical field [0001] The invention relates to a soil anchor head, in particular to a steel bar casing-less soil anchor head, which belongs to the technical field of anchoring. Background technique [0002] The soil anchor is to drill a hole in the unexcavated soil layer of the deep foundation soil wall. After reaching a certain depth, put steel bars, steel pipes, steel wire bundles, steel strands and other materials into the holes, and pour mud or chemical slurry to make them It combines with the soil layer to become an anchor rod with strong tensile (pull) force. The end of the soil anchor rod is connected with the retaining pile to prevent the soil wall from collapsing or landslide; and since there is no support in the pit, the construction conditions are better. [0003] At present, there is no soil anchor for anti-floating, and traditional engineering uses anti-floating piles to realize this function. However, compared with the soil anchor, the anti-floating pile has...
