GY-80 Crawler Type Anchor Drilling Rig
Feature:
1. Anchoring can be suitable for the construction methods of drill
pipe drilling, casing drilling, and composite drilling of drill
pipe and casing. Rotary jets can be suitable for single, double,
and triple rotary jetting.
2. Adopting full hydraulic power head drive with step-less variable
speed, high drilling efficiency, and low labor intensity.
3. The power head adopts hydraulic variable speed and has high and
low gears to meet the requirements of various formations and
different drilling processes, adds hydraulic rear top hammer type
impact function, and realizes the integration of impact and rotary
structure. This not only enables the drilling rig to quickly drill
into general rock formations but also achieves fast drilling in
sand and gravel layers as well as cobble layers while ensuring a
significant reduction in the number of accessories, reliable
quality, and easy maintenance.
4. Reverse drilling device: When sticking occurs during drilling,
the drill pipe can be quickly removed by striking the drill pipe
with the reverse drilling device.
5. Frequency regulation: Hydraulic impact drill cylinder with
manual frequency regulation device, can be adjusted according to
different geological conditions.
6. Direct-acting load feedback fine-tuning variable hydraulic
system, power varies with load, high efficiency, low energy
consumption.
The main components of the hydraulic system of the drilling rig
adopt famous brands, with a stable and reliable system and long
service life.
7. The drilling rig has a self-propelled crawler function, which
makes it easy and fast to move the equipment.
8. Equipped with a rotary, the hole position can be turned to the
side of the track to work when needed.
9. Compact structure, centralized operation, convenient and safe.
Application:
GY-80 crawler-type fully hydraulic engineering drilling rig is used
for foundation reinforcement, water isolation, leakage plugging,
soft foundation treatment, geological disaster management, and
anchoring for controlling building displacement in various
industrial and civil buildings such as railroads, highways,
bridges, road foundations, and dam foundations. It can be used for
rotary drilling with common alloy drill bits and other drilling
tools; it can be used for impact rotary drilling in rock layers and
high-speed hole formation with conventional ball tooth bits; it can
be used for drilling holes with casing in unstable strata such as
pebble layers and other unstable strata with follow-the-pipe
drilling tools; it can be used for hydraulic impact to meet the
requirements of impact rock-breaking hole formation, liquid
discharge, underground mini-pile, anchor rod, and anchor cable,
geological exploration, geothermal hole formation, foundation
reinforcement, and slope support. The construction requirements of
infrastructure construction, such as the choice of a rotary jet
module with rotary jet function (swing jet, fixed jet). It can also
carry out the construction of over-the-tunnel pipe shed support and
geological pre-prospecting.
