Most wind generator mainly used in wind farms adopt anchor cage foundation, main function of anchor plate is to connect the bolt and concrete structure
In the design and construction of mining roof bolts support, support forms and parameters are selected based on experience or engineering analogy, so there are some problems, such as difficult roadway maintenance, low coal production rate and tight mining replacement.
Here is a sample of small steel mill for rock anchor bolt production. Steel Mill adopts all rolling system, the air and gas – double heat furnace, use steel billet as raw material, with alternate arrangement of 6 roughing mills, and finishing mill group
Nowadays, rebar rock bolt tunnel support technology has become an indispensable technology in coal roadway support. In the supporting system, rebar rock bolt is the most widely used product. Here are some details of how high quality rebar rock bolt is manufactured:
The high strength hot-rolled structural tie rod used in Zunyi Science and Technology Museum has a diameter of 80mm, a length of 1L643m, 1L323m and 1L418m, respectively, and tensile strength of not less than 650MPa.
Structural tie rod anti-corrosion treatment is very important for the life span of the building if it is done improperly, structural tie rod might be corrosion influenced, which will lead to more maintenance work. And this can be avoided by good anti-corrosion treatment work.
Lonteng Group supplied the M48 Anchor Bolt assembly to all 45 wind turbine foundations, and helped with onshore anchor cage foundation construction.
Anchor rock bolt are solid or hollow steel rock bolts that are drilled into rock mass during excavation of the surrounding rock to avoid loose collapse of rock mass, which serves to reinforce and connect the soil body as a whole.
The connection of high-strength precision-rolled threaded steel bar is to prevent mutual sliding of connecting parts by friction between contact surfaces.
Rock bolt used as roof bolt is a main method to provid safe working environment for miners, prevent ground falls and save human lives and properties from hazards.
