1. Electric drive rock pipe jacking machine is mainly suitable for gravel, pebbles, a small amount of boulders and rock strata.
2. The cutterhead has high power and is equipped with a large-torque reduction gearbox, which has strong rock breaking ability.
3. The main jacking has a fine adjustment mode, which can realize millimeter-level accuracy adjustment per minute and meet the construction requirements of extremely hard rock strata.
4. The mud discharge system can realize five mud circulation modes: internal and external circulation, bypass, external water supply and direct drainage, effectively solving the problems of slag deposition and large frictional force of pipeline.
5. It is equipped with a telescopic anti-rotation device to effectively solve the problem of easy rotation of the machine head during construction in rock strata.
