Drilling Rig Tools
Exploration engineering commonly used in engineering geology includes drilling and excavation.Our company mainly provides drilling tools to meet various construction techniques of engineering geological drilling: divided into rotary drilling tools and impact drilling, as well as impact rotary drilling tools.Users can select and match according to their own construction needs.Rotary drilling tools: including all types of drill, drill pipe and supporting construction tools.The bit has alloy bit, steel grain bit and diamond bit, and various drill pipes are provided according to different bore sizes (refer to relevant specifications of geological survey tools of our company)
Percussion drilling tool
For the need to provide a variety of follow - pipe drilling tools and impactor.In the sand and gravel drilling, also can use the method of penetration sampling drilling.A half-closed sleeve with a diameter of 150mm ~ 200mm was used to grow about 0.5m. The lower end was connected with the boot with a spring, and the upper end was connected with the casing.When drilling, drive the casing into the bottom of the hole about 0.4m, then pull out the casing, take out the sand and gravel, and then drive the wall pipe.Thus, the drill, sampling, until the final hole.
Impact rotary drilling tools
The drilling method that combines the impact and rotary drilling is that the drill bit applies the impact load at the same time as the rotary crushing rock at the bottom of the hole.
