The invention discloses an engineering geological drilling construction method based on a wire line coring drilling tool. A single-action double-barrel drilling tool is adopted, a coring bit is installed at a lower end of an outer barrel, a core barrel is installed at a lower end of a spring clamp, the spring clamp is suspended inside an outer barrel assembly, and an upper end of the outer barrel assembly is connected with a power head; after a drilling depth reaches the length of the core barrel, the whole drilling tool is lifted to pull off rock cores; an inner barrel assembly is fished out to replace for another set; after the drilling reaches an expected drilling depth, the inner barrel assembly is fished out, while the drilling rod and the outer barrel assembly remain still in a drilling hole; a standard penetration test is carried out.
