Supporting structure with dedusting and grouting functions for tunnel construction

The invention discloses a supporting structure with dedusting and grouting functions for tunnel construction, and relates to the technical field of supporting structures for tunnel construction. The supporting structure comprises a main body and rubber blocks, movable wheels are movably arranged at the bottom of the main body, telescopic rods are movably arranged on the two sides of the bottom ofthe main body, the rubber blocks are arranged on the bottom of the telescopic rods, and main hydraulic rods are movably arranged on the two sides in the main body and connected with the main body through screws. The supporting structure has the advantages that the telescopic rods are movably connected with the main body so that the supporting performance of the device can be improved by opening the telescopic rods when the device needs to be fixed for use for a long time, and it is guaranteed that the device cannot topple over; meanwhile, the rubber blocks are fixedly connected with the telescopic rods so that the rub
