With the evolution of tunnel construction technology,，The maintenance technology in the construction is also increasingly sophisticated.。Xizhu Company has successfully developed and tested the first spray maintenance trolley recently.，The equipment integrates advanced spraying and precision control technology.，Ensure full and uniform maintenance of the tunnel wall。

In tunnel construction，Concrete wall maintenance is very important，Improper curing can easily lead to shrinkage cracks.，Damage to structural safety and life。Xizhu spray maintenance trolley with its precise spray mechanism，Ensure sufficient wetting of the concrete during hardening，Significantly reduce the risk of desiccation cracking，Improve project quality。
The intelligent level of this trolley is remarkable.，Automatic back and forth spraying，It also has the function of humidity sensing to regulate the amount of water spraying.，Overcomes the problems of unevenness and low efficiency of the traditional method.，Achieve efficient maintenance。Its two-ton large-capacity water tank，Multiple operations are supported by single water addition，Optional constant temperature system for high altitude and low temperature environment。
