when the concrete baffle is used: the method comprises the steps of pulling out a rigid metal plate (1) from a pile core through a metal handle (4), welding one side, provided with a stainless steel metal sheet (2), of the rigid metal plate (1) with a prefabricated reinforcement cage in a point-to-point mode, inserting one end, provided with the metal handle (4), of the rigid metal plate (1) into the pile core towards a pipe pile head, bending the stainless steel metal sheet (2) into ninety degrees under the extrusion of the side wall of the pile core, fixing the position of the prefabricated reinforcement cage through a positioning reinforcement after the rigid metal plate (1) is inserted into the preset position, and attaching the rigid metal plate (1) to the inner wall of the pile core through a flexible rubber ring (3) at the moment, so that pile core concrete leakage is prevented, and the concrete compactness of the pile core is guaranteed.
