Scope of application:
Drilling machine is divided into positive circulation drilling machine and reverse circulation drilling machine according to mud circulation mode. Positive circulation drill is suitable for the construction of pile foundation of bridge pier in clay, silt, sand soil and other soil layers. Reverse circulation drill is suitable for clay soil, sandy soil, pebble soil and weathered rock, but the particle size of the pebble is less than the inner diameter of the drill pipe2/3, and the content is not greater than20%.
