XL-50C Jet grouting anchor drilling rig
Application
Applicable to the railways, highways, bridges, dam foundation, and various industrial and civil building foundation treatment and reinforcement of jet grouting construction;Anchorage engineering of foundation pit support;Matching with air compressor and pneumatic DTH hammer, it can be used for pipe drilling, general rotary spraying (swing spraying, fixed spraying) engineering construction, but also for shallow hole drilling and engineering survey drilling and other engineering construction.
Main feature
1、Adopt full hydraulic control, easy and flexible operation, crawler chassis loading, walking, moving position is convenient and fast, power head stroke is long, reduce auxiliary time.
2、 direct load feedback fine-tuning variable hydraulic system, power changes with the load, high efficiency, low energy consumption.
3、The special valve with friction positioning is used in rotary rotation, and its characteristics fully meet the requirements of rotary jet technology.
4、The variable speed range of the power head is wide, which can meet the requirements of various formations and different drilling techniques.
5、Equipped with slewing support, the hole can be turned to the side of the track when needed.
6、Compact structure, centralized operation, convenient and safe.
7、Equipped with drilling tower vertical, power head rotation and lifting speed display device.
Supporting drilling tools
1、Single-tube drilling and spraying integrated method, the front end is equipped with a three-wing drill bit or a flat-shaped drill bit to drill a twisted 42 or Ф50 drill pipe; it is suitable for high-speed drilling of soil layers, sand layers and other formations.
2、Spiral jet anchor cable method, with 65 lock bolt propeller and anchor cable drilling pipe, is suitable for anchor cable reinforcement.
3、Single pipe, double pipe, three pipe rotary spray, swing spray, fixed spray, etc.
