Earth accumulation protection device for building earth excavation

The utility model belongs to the technical field of earthwork protection, and discloses a building earthwork excavation earthwork accumulation protection device which comprises a plurality of fixed piles arranged on the same horizontal plane according to a rectangular structure; the multiple baffles are arranged, the multiple baffles are arranged between every two adjacent fixing piles, and the two ends of each baffle are detachably connected with the side faces of the corresponding fixing piles; and the multiple fixing cones are arranged, and the multiple fixing cones are detachably connected to the lower surface of the fixing pile and the lower surface of the baffle in the vertical direction. Due to the fact that the fixing cones are installed on the lower surface of the fixing pile and the lower surface of the baffle, the fixing cones are inserted into the land, and each fixing cone is a fixing point, the reinforcing strength of the fixing pile and the baffle is improved, and earthwork can be better reinfo
