IntroductionHANFA RC reverse circulation drilling rig is a crawler chassis loaded, fully hydraulically driven, power head type drilling rig. It is a drilling equipment suitable for vertical or inclined drilling and is suitable for the following process methods:Non-circulating fluid spiral drilling (dry drilling)Air down-the-hole hammer (pneumatic impactor) drillingMud positive circulation drillingAir down-the-hole hammer and pipe drillingMulti-media reverse circulation drillingThe drilling rig is suitable for different drilling process methods, so it has greater adaptability to various formations and complex working conditions, and can effectively solve the problem of difficulty in drilling holes in loose covering formations, gravel layers, and bedrock broken formations, and has a very wide range of uses.

Application：

The drilling rig is mainly suitable for the construction of RC reverse circulation, ground source heat pump holes, urban deep foundation pit support and foundation reinforcement engineering holes; it is also suitable for the construction of large-tonnage prestressed anchor holes or drainage holes in geotechnical engineering such as hydropower station projects, railways, and highway slopes, as well as landslide prevention and rock collapse disaster management projects; and it also takes into account the survey and construction of tunnel pipe shed support holes, grouting reinforcement holes, small foundation pile holes, and hydrological wells.
