Shotcrete recovery device

Abstract

The present utility model relates to the field of construction technology, in particular to a shotcrete recovery device in tunnels. The shotcrete recovery device in tunnels comprises a transport vehicle (1), wherein the top of the carrier platform of the transport vehicle (1) is equipped with a concrete spraying machine (3), a collection container (16) and a cylinder (8); the bottom of the collection container (16) is connected to a first screw conveyor (7); the outlet end of the first screw conveyor is connected (7) to a second screw conveyor (5); the outlet end of the second screw conveyor (5) is connected to the concrete spraying machine (3); the outlet end of the cylinder (8) is fixedly connected to a lifting frame (9); the side surface of the lifting frame (9) is fixedly connected to a lifting partition plate (11) via several connecting rods (10); and the lifting partition plate (11) is arranged around the left side of the collection container (16). The present utility model enables the collection and recovery of return concrete during shotcrete operations on tunnel arches. Recycled concrete can be reused, which not only saves resources but also reduces costs, thus increasing the practicality of the device.
