Roof Bolter, also known as soil nailing machine and pneumatic impact machine, is mainly used for geotechnical bolting, roadbed, slope treatment, underground deep foundation pit support, tunnel surrounding rock stabilization, landslide prevention and other disaster remediation, underground engineering support and High-rise building foundation treatment. It is also suitable for spray protection of deep foundation pits and non-prestressed bolt support for slope soil nailing projects.
Roof Bolter Application:
The Roof Bolter is suitable for soil nails made of various materials (such as angle steel, rebar, steel pipe, etc.). Two methods are generally used to make soil-nailed walls: one is to insert reinforcement through drilling holes, and then grouting to form mortar anchors. This method is time-consuming and expensive, and it is not easy to construct the quicksand layer and the sand-stone layer. The second is to make soil nails from threaded steel bars, angle steel, steel pipes and other materials and drive them into soil layers or sandstone layers mechanically or manually to form soil nail walls.
The bolter is light in weight and compact in structure, which is conducive to moving and relocation. Its impactor and pneumatic accessories are all well-known brands. The bolter is composed of the main engine (cylinder, impactor, hammer), operating table, air duct, etc.
