Wet shotcreting jumbo is an important equipment in tunnel construction.，It is mainly used for highway、Railway、Water conservancy and other underground works and slope wet shotcreting operation。Restricted by the low cost of domestic labor force and the high one-time investment cost of mechanized construction.,The mechanization level of tunnel drilling and blasting construction in China once stagnated.。With the continuous development of tunnel construction technology,，The technical requirements and performance requirements of the wet spraying trolley are also getting higher and higher.。At present，There are some problems in the wet spraying trolley on the market.，Uch as poor reliability、Construction power is weak、Low addition rate of accelerator, etc.，Unable to meet the high efficiency of tunnel construction、Safe、High quality requirements。For these pain points，Xizhu Company has actively developed and optimizedSPG401 6 andSPT4016 wet spraying trolley，Strive to break the technical bottleneck，Realize the high efficiency of tunnel construction、Safety and high quality。

SPG401 6 andSPTThe 4016 wet spraying trolley not only inherits the advantages of the traditional wet spraying trolley，It also achieves breakthroughs in design and function.。The trolley is equipped with four-wheel drive and four-wheel steering、Pumping automatic anti-blocking pipe technology、Large Proportion Addition of Accelerator and Intelligent Control System、Air path remote control system，It greatly improves the intelligent level of the equipment.，Ffectively improve that construction efficiency and quality。Successful Development of Wet Spraying Trolley in Xizhu Company，It not only fills in the blank of China Communications Group in the field of mountain tunnel equipment.，It also marks a new breakthrough of Xizhu Company in the field of tunnel installation.。
