The invention discloses a construction method of a square-shaped slide-resistant pile. The construction method of the square-shaped slide-resistant pile relates to the field of slide-resistant pile construction, and comprises a covering layer construction step and a rock stratum construction step. The covering layer construction step comprises the steps of adopting a matching way of a first drillbit and a second drill bit, taking the size of the outer side of a fore shaft as a boundary, and drilling a covering layer area corresponding to an area within the boundary until arriving at a presetposition, wherein the diameter of the first drill bit is smaller than the diameter of the second drill bit; adopting a whole hoisting machine for hoisting a wall protection reinforcing steel bar, andthen installing a wall protection steel moulding plate; and casting wall protection concrete, and disassembling a mold when the strength of the concrete achieves the preset strength. The covering layer construction step comprises the steps of adopting a matching way of the first drill bit and the second drill bit, taking the size of the outer side of a protection wall as a boundary, and drilling arock stratum corresponding to an area within the boundary until arriving at designed elevation; and carrying out slide-resistant pile reinforced concrete construction, and finishing. The constructionmethod of the square-shaped slide-resistant pile provided by the invention is high in construction efficiency, low in safety risk and low in cost.
