The invention discloses an anti-blockage reinforced permeable pile and a construction method. Permeable geotechnical cloth is reinforced; and two-way geotechnical grids are added to form a geotechnical cloth cylinder, so that the molding capacity of a pile body can be improved, and the strength of the pile body of the permeable pile can be improved. The geotechnical cloth cylinder is wrapped witha permeable concrete pile to form a bagged permeable concrete pile, so that excellent permeability can be guaranteed, and soil particles can be reduced to enter to prevent blockage of the permeable concrete pile; and the geotechnical grids are higher in tension strength to tightly surround the pile body, so that the pile body is higher in strength and modulus, and the deformation and destruction resistance is improved.
