Mechanical cutting drilling tools-trenchless drilling tools
2021-12-02
Trenchless engineering drilling tools. Trenchless construction technology is a new technology for underground engineering construction, which has been applied in China's engineering construction for less than 10 years. Because this technology can carry out drilling operations without digging the surface, it does not affect traffic, does not damage the environment, and has a short construction period, so it is widely used in municipal engineering and underground pipeline laying projects such as rivers, railways, highways and airports.
Reverse patio rock drilling tool
2021-11-16
Domestic underground metal mine shaft construction is mainly based on drilling and blasting method. In recent years, with the progress and development of roadway non-destructive mechanized tunneling technology and equipment, reverse patio drilling rig has begun to be applied in some large underground metal mines. In the underground metal mine shaft excavation, the use of the construction method of the patio drilling rig has a series of advantages such as fast excavation speed, low labor intensity, no damage to the original integrity and stability of the roadway rock, the shaft wall is rounded, the well quality is good and conducive to ground pressure control, it is an advanced construction method of underground mine shaft excavation. In our country, with the technological progress of the mining industry, the reverse patio drilling in the shaft drilling construction has
What is mining tooth wheel drilling tool
2021-11-08
Mining tooth wheel drilling tools are mainly used for vertical perforation operations in large open-pit mines, earth and rock drilling, water wells and geothermal wells. During the drilling process, the tooth wheel drilling machine drives the rotary motion of the tooth wheel drill bit through the drill rod, and at the same time exerts a downward thrust for the drilling tool to drill the hole. Under the action of rotating force, the tooth wheel drill drives three teeth inlaid with hard alloy teeth or steel teeth to rotate around their respective claw journals. At the same time, under the action of axial thrust, the alloy teeth or steel teeth are embedded into the surface of the rock, and the rock is broken by the alternating composite force of extrusion and shear, so as to achieve the purpose of perforation.
What kind of down-the-hole percussion drilling tool
2021-10-28
Different from the top hammer impact rock drilling tool, the down-the-hole impact rock drilling tool is a kind of large-diameter drilling and blasting method with compressed air as the power source, and the power part enters the rock hole to drill rock. At present, it is widely used in rock drilling engineering at home and abroad.
Full hydraulic drilling tools for open-air drilling vehicles
2021-10-14
The full hydraulic open-pit rock drilling rig is a rock drilling machine widely used by the domestic construction department, mainly used in open-pit mines, cement and building materials industry stone market, construction industry and road engineering quarry construction.
Drilling tools for rock drilling
2021-09-30
There are two kinds of construction methods of rock drilling and blasting excavation method and mechanical rock breaking excavation method. Domestic construction is mainly based on rock drilling, drilling and blasting excavation method, and its operation area is concentrated in tunnels and culverts in infrastructure engineering construction and well excavation in underground mine production and construction.
