Combined type foundation pit supporting inclined strut device

The invention discloses a combined type foundation pit supporting inclined strut device and aims at providing the combined type foundation pit supporting inclined strut device which can effectively solve the problems that construction of a coping beam and construction of an inclined pile support in an existing foundation pit restrict each other, the coping beam and the inclined pile support cannot be independently constructed, and the construction progress is prone to being affected. The supporting structure comprises supporting inclined piles, the supporting inclined piles are distributed in an inclined mode, the lower portions of the supporting inclined piles are buried in a soil layer on the bottom face of a foundation pit, and the upper ends of the supporting inclined piles face a purlin beam or a coping beam of the foundation pit; the beam connecting seat is fixed on the purlin beam or the coping beam; the pile connecting base is fixed to the upper end of the supporting inclined pile, and the pile connec
