Description
technical field [0001] The invention relates to the field of tunnel construction machinery and equipment, in particular to a sediment spraying device for tunnel maintenance. Background technique [0002] During the construction and maintenance of the tunnel, it is necessary to spray the silt concrete to the tunnel section. The current spraying work is usually carried out with a spray truck. The working principle of the spray truck is to use compressed air to transport the ready-mixed concrete mixture to the At the nozzle of the jetting machine, the material bundle is formed after being mixed with the accelerator, which is sprayed onto the surface to be sprayed at high speed, and then condenses and hardens rapidly to form a concrete support layer. Wet shotcrete technology is widely used in various construction fields because of its simple process and economical cost. Most of the jet machines used at present are small machines, and the supporting parts are scattered and arran...
