Applicable geological conditions
1. Hard and medium hard rock layers
Suitable for hard or medium hard rock formations such as granite,
basalt, limestone, sandstone, etc., especially with high drilling
efficiency in rock formations with developed fractures.
It also has certain adaptability to loose strata such as weathered
rock layers, gravel layers, and pebble layers, but it needs to be
accompanied by casing protection to prevent hole collapse.
Exploration and development of aquifers
Commonly used in areas with abundant groundwater, such as alluvial
plains, river terraces, and sloping plains in front of mountains,
it can quickly locate aquifers and form wells.
2. Application scenarios
Civil and industrial water supply
Construction of domestic water wells and small water supply plant
water source wells in remote areas such as rural and mountainous
areas.
Drilling of self owned water source wells for industrial production
(such as mines and factories).
3.Agricultural irrigation
The construction of irrigation wells in farmland, orchards,
greenhouses, etc. is particularly suitable for groundwater
development in water scarce areas.
Geological Exploration and Scientific Research
Shallow drilling sampling in geological exploration,
hydrogeological investigation, and engineering geological
exploration to obtain data on formation lithology, groundwater
parameters, etc.
Disaster relief and emergency water supply
Rapid excavation of temporary water source wells after disasters
such as earthquakes and floods to meet short-term emergency water
needs.
Special environmental homework
High altitude/remote areas: No need to rely on the power grid, can
be powered by an air compressor, suitable for areas with low
electricity or inconvenient transportation (such as plateaus,
deserts, jungles).
Water scarce environment: Pneumatic drilling rigs are powered by
air, reducing dependence on water resources, and have significant
advantages in arid areas.
