Disclosed is a mixing and guniting device of a new type for a TBM, wherein the device comprises a concrete inlet pipe (), a four-way pipe (), a nozzle (), an agitator motor (), a longitudinal swing oil cylinder (), a flow mixer, a lateral swing oil cylinder (), a telescopic oil cylinder () connected to a big arm, and a controller, one end of the telescopic oil cylinder () being provided with a connection plate (), the four-way pipe () being fixed on the upper part of the connecting plate (), two interfaces in the upper part of the four-way pipe () being respectively provided with an air inlet pipe () and an accelerator inlet pipe, a measuring sensor connected to the controller being provided in the air inlet pipe (), two interfaces in the lower part of the four-way pipe () being respectively provided with bent pipes (), the other ends of the bent pipes () being in communication with the flow mixer, the nozzle () being provided in the upper part of the flow mixer, the concrete inlet pipe () being provided in the lower part of the flow mixer, and the concrete inlet pipe () being in communication with the nozzle () and the bent pipe () via the flow mixer. The mixing and guniting device can adjust the distance and the angle between the nozzle and a sprayed face intelligently and in real time according to the air flow, so as to ensure a suitable distance at which the rebound rate is lowest and the best angle at which the nozzle is always perpendicular to the sprayed face, such that the rebound rate is effectively reduced with less loss of concrete, energy conservation and environmental protection.
