Concrete rapid leveling construction method of basement bottom plate

The invention discloses a concrete rapid leveling construction method of a basement bottom plate. The method comprises the following steps that S1, a concrete cushion is poured on a bottom plate baselayer; S2, waterproof and protection layer construction is carried out on the concrete cushion; S3, bottom plate steel bars and bearing table bottom layer steel bars are paved; S4, stirrups and a guide rail support used for rapid leveling are placed on the concrete cushion; S5, plate face bars are paved, and a guide rail is placed on the guide rail support; and S6, concrete is poured, a flat platevibration table is dragged on the guide rail to carry out vibration leveling, the guide rail is constantly drawn to move forwards along with concrete pouring, and the guide rail is repeatedly used till construction is completed. After the above construction method is adopted, concrete leveling construction of the basement bottom plate is simple, the pouring speed is high, bottom plate leveling height limiting is achieved
