The P series single action double-layer core pipe drilling tools are widely used in engineering geological exploration and geological core drilling. The combination of various drill bits and sampling tubes can effectively improve the sample recovery rate and completeness. Its derivative varieties include three-layer tube sampling tubes, semi composite tube sampling tubes, and expansion tube sampling tubes, which can respectively meet the requirements of geological core drilling, engineering and hydrogeological exploration, concrete grouting pile inspection, and soft foundation treatment sampling.

Characteristic 1. Unique single action structural design, good single action performance, reliable sealing, and long service life< br/> 2. Equipped with a sampling cylinder assembly adjustment mechanism, it can adjust the axial position of the sampling cylinder according to geological conditions, which is conducive to improving the rock sample recovery rate< br/> 3. Equipped with a one-way valve mechanism, it facilitates the entry of rock cores into the sampling cylinder< br/> 4. Equipped with an upper supporting wear-resistant stabilizing ring, it improves the rotational stability of drilling tools and reduces drilling tool wear.
