This invention relates to the field of soil and rock sampling technology, specifically to a soil and rock sampling drilling device and method for geotechnical engineering. The device includes a C-shaped support, with a telescopic cylinder fixedly connected to the top of the C-shaped support. The bottom end of the telescopic cylinder's telescopic rod passes through the bottom of the cross plate of the C-shaped support, and a C-shaped plate is fixedly connected to the bottom end of the telescopic cylinder's telescopic rod.
