In recent years, wet concrete spraying shotcrete technology has become a popular construction technology for railway, roads and water conservancy tunnels, but small and medium-size wet shotcrete machines have some disadvantages such as low spraying efficiency, high consumption of consumable parts, large investment for labor and equipment. At present, choosing robotic arm shotcrete machine manipulator has become the mainstream method of tunnel foundation construction.Many people are not clear about the operation steps of the concrete wet spray manipulator. Today, SINOGROUT in Zhengzhou will share with you the operation steps of the concrete wet spray truck/concrete wet spray manipulator.
What is a robotic arm concrete spraying shotcrete machine?
Tunnel wet concrete spray shotcrete manipulator is a large and medium-sized intelligent wet shotcrete system, also known as robotic arm wet shotcrete machine. It combines walking system, pumping system and spraying system and widely used in tunnel engineering projects, water conservancy and hydropower engineering, municipal road engineering, road and bridge engineering, engineering construction, etc.
Robotic Shotcrete machine manufacturer indicated that the shotcrete bolt-shotcrete support followed the excavation surface, and shotcrete bolt-shotcrete support was divided into primary shotcrete and secondary shotcrete. The initial spraying should be carried out immediately after the end of foundation pit excavation (or excavation of each section), so as to close and expose the soft rock as soon as possible and avoid the weathering layer of the excavation face falling off. After the installation of anchor cable, tag or steel frame structure, the overall bearing force of shotcrete and anchor support can be generated as soon as possible to restrain the displacement of soft rock.
The key equipment of concrete spraying shotcrete are mainly divided into two types: dry shotcrete and wet shotcrete. Compared with dry shotcrete machine, small and medium-sized wet shotcrete machine, wet spraying concrete robotic arm shotcrete machine vehicle is large and medium-sized intelligent system of mechanical equipment, also known as wet spraying manipulator, mechanical arm wet spraying machine, greatly reduces the worker labor efficiency, improve the work efficiency, optimize the construction conditions, reduced the engineering cost, and can meet all kinds of construction under the condition of wet spraying operations.
Concrete spray wet shotcrete vehicle operation steps
Wet concrete spraying shotcrete vehicle construction workplaces are prepared ahead of time → wet spraying concrete robotic arm shotcrete vehicle arrive the construction site and prepare → run hydraulic transmission system → run air compressor → run mixing silo→ charging → cleaning the sprayed surface → gradually wet spraying operations → wet spraying finished → shutdown the equipment and clean the pipes and hoses →left workplace and go to maintenance place → carry out the maintenance of the machine → wait for the next cycle of normal use after maintenance.
Operation advantages of concrete wet shotcrete vehicle:
Concrete wet shotcrete vehicle has the advantages of high degree of mechanization, reduced rebound rate, high production efficiency and so on. It is widely used in construction, municipal engineering, railway, mining and other related underground pavement anchor shotcrete support engineering.
Concrete spray wet shotcrete system is a large and medium-sized intelligent system wet shotcrete manipulator which adopts wireless remote control and output is 30 m3/h. It’s widely used in railway lines, roads, hydropower engineering, highway bridges, tunnel construction and mining projects and other industries of shotcrete operations.
