The wet spraying manipulator is an advanced equipment widely used in tunnel construction and underground engineering. It has many aliases, such as spraying manipulator, wet spraying concrete spraying machine, wet spraying concrete transport vehicle, etc. It is mainly used in pre-reinforcement treatment, grouting, steel bar processing, tunnel lining, and roadbed engineering. This equipment has the advantages of small size, convenient movement, simple operation, uniform spraying, time and material saving, etc., so it is favored by users.

　　Especially in the construction of highway tunnels, the application of wet spraying manipulators can significantly improve the construction environment, increase work efficiency, shorten the construction period, and also improve the construction quality of tunnel projects.

　　The LHP40K wheeled wet spraying manipulator developed by Blue Ocean Intelligent Equipment is a special equipment, which has been upgraded through the research and development of tunnel initial support concrete grouting process and construction conditions below 2000 meters above sea level. Its maximum spraying volume reaches 40m?/h, suitable for full-section and half-section construction, with the characteristics of large spraying volume, not easy to block pipes, low rebound, stable and reliable performance, etc.

　　The advantages of this equipment include: suitable for construction below 2000 meters above sea level without the need for external air source; high grouting efficiency, not easy to block pipes; using dual diesel-electric systems, with emergency construction capabilities; equipped with dual-speed admixture tanks to meet the needs of large-section construction.

　　Wet spraying manipulators have been widely used in tunnel engineering, water conservancy engineering, municipal engineering, road and bridge construction, and other fields, contributing to the infrastructure construction of our country.
