The invention discloses an engineering geological drilling construction methodbased on a wire line coring drilling tool. A single-action double-barreldrilling tool isadopted, a coring bit is installed at a lower end of an outer barrel, a corebarrel isinstalled at a lower end of a spring clamp, the spring clamp is suspendedinside anouter barrel assembly, and an upper end of the outer barrel assembly isconnected witha power head; after a drilling depth reaches the length of the core barrel,the wholedrilling tool is lifted to pull off rock cores; an inner barrel assembly isfished out toreplace for another set; after the drilling reaches an expected drillingdepth, the innerbarrel assembly is fished out, while the drilling rod and the outer barrelassemblyremain still in a drilling hole; a standard penetration test is carried out.
