Abstract
The invention discloses a double-pipe bottom mud sampler. The double-pipe bottom mud sampler comprises an outer guide pipe, an inner guide pipe and a sampling barrel. The inner guide pipe internally sleeves the outer guide pipe, and the outer guide pipe and the inner guide pipe are connected through a transverse bolt. The sampling barrel comprises an inner barrel and an outer barrel, the inner barrel internally sleeves the outer barrel, and the inner guide pipe is connected with the inner barrel through a vertical bolt. The outer guide pipe and the outer barrel are connected through long metal strips. Openable seal covers are arranged at the bottom of the outer barrel and connected with the inner barrel through steel wire ropes which are welded to the inner barrel and the seal covers. When the double-pipe bottom mud sampler drills downwards, excessive bottom mud is discharged through the open seal covers and gaps among the long metal strips; when the double-pipe bottom mud sampler is lift upwards, totally-closed sampling is realized by the closed state of the seal covers and the sealed state of the top of the sampling barrel. The double-pipe bottom mud sampler has advantages of reasonability in principle, simplicity in operation, portability, high airtightness and low soil disturbance.
