Two adjacent baffles are connected by inserting a connecting rib one into a connecting groove one, and the lower part of the baffle is inserted into a base. The stabilizing structure includes a stabilizing frame and a fixing part. The side of the stabilizing frame away from the foundation pit is fixed in the earthwork slope by the fixing part, and the side of the stabilizing frame close to the foundation pit is detachably connected to the side of the baffle close to the earthwork slope; the two adjacent baffles are connected by inserting the connecting rib into the connecting groove, which can increase the sealing of the connection between the two adjacent baffles and prevent the loss of sand and soil in the earthwork slope.
