Before starting the construction, it is good to know your conditions! Investigating the soil is a good way to map the challenges ahead. And then, we can choose the suitable drilling equipments.

Commonly Used Methods
Depending on ground conditions and required drilling depth, core drilling or RC drilling can be the methods of choice.
SPT (Standard Penetration Tests) are performed by recording the number of hammer blows and are needed to drive up a sample tube to certain depth in to the ground. This would indicate the relative density of the soil.

Applications of Various Drilling Equipment
In the mineral deposit exploration, especially the non-ferrous and rare metal exploration, the tunnel drilling rigs are used for ore deposits searching, exploration and reconnaissance of geologic structure ore body as well as sampling and verification.
The engineering drilling rigs are applied to geotechnical foundation constructions, including building base, plant foundation, high-speed rail base and road infrastructure.
The drilling equipment is generally used to drill observation wells, vent holes, drain holes, gas drainage hole, grouting hole, blasting holes, anchor holes and the pilot hole.
In other areas of geotechnical engineering, the tunnel drilling rig and technology can be used for slope strengthening of dam foundation, governance of geological disasters, deep excavation pit supporting, as well as underground constructions at the aspects of industrial, commercial, transport and military.

As a professional drilling equipment manufacturer and supplier, we have anchor drilling rig, jet grouting drill rigs, engineering drilling rig, multifunctional drilling rigs, tunnel drilling rig and water well drill rig for sale. We have received the ISO9001-2000 quality system certification, and in 2012 passed the GJB9001B-2009 certification. Our engineering drilling rigs have been exported to Vietnam, Brunei, Singapore, Iran, Britain, Canada, Nigeria and other countries and regions.
