    ST 350 Crawler Mounted Drilling Rig Advantages:


    (1) High slag discharge wind speed, clean hole bottom and no secondary crushing; Because there is no liquid column pressure, the hole bottom crushing condition is improved without groundwater;
    (2) The drilling method of pneumatic water well drilling rig is to impact the hole bottom with high frequency, which reduces the influence of hole inclination on rock or inclined stratum, so as to improve the verticality of drilling hole and reduce the rock collapse of hole wall;
    (3) Compared with rotary well drilling rig, pneumatic well drilling rig requires much less WOB and torque. This can reduce the quality and capacity of drilling equipment and create favorable conditions for large-diameter hard rock drilling;
    (4) Pneumatic water well drilling rig has good adaptability and can work under various complex rock strata (including aquifer);
    (5) The utility model has the advantages of simple structure and convenient use and maintenance.
