Vehicle mounted hydraulic wet spraying machine, precise and constant hydraulic wet spraying machine, jog

Description :

　　Hydraulic wet spraying machines can be divided into hydraulic pumping wet spraying machines and piston wet spraying machines based on their working principles. The hydraulic wet spraying machine has more stable performance and is derived from the concrete pump. The vulnerable part is one pair of eyeglass plates. The other components are very durable, but their disadvantage is that they are a bit bulky. Don't move.

　　Objective of the test

　　Spraying concrete is used for initial support or temporary protection inside tunnels. It can be used as a separate protective structure or combined with anchor rods, steel mesh, steel frames and other supporting structures to form a spraying anchor construction system. It is a common supporting structure in tunnel construction, mainly used to seal the surrounding rock, prevent its relaxation and weathering. Due to the increased requirements for self waterproofing performance of the support system and ventilation and dust prevention in tunnel construction, wet shotcrete is used for initial support in the tunnel. Wet shotcrete has strong waterproof performance and can effectively suppress the generation of dust in tunnels (compared to dry shotcrete). When constructing the shotcrete support system, careful observation and analysis of the water seepage of the surrounding rock should be carried out. For areas with high water seepage, measures such as buried pipe drainage or radial grouting should be taken to block the water. To ensure that the strength, thickness, and rebound of wet shotcrete meet the design and specification requirements, wet shotcrete process tests are conducted. The main purpose of the experiment is to obtain reasonable wet shotcrete parameters through wet shotcrete testing, which can be used to guide future wet shotcrete construction.
