Subway station prefabricated side wall and bottom base grouting connection construction method

A subway station prefabricated side wall and bottom base grouting connection construction method comprises: manufacturing a bottom base on site; dividing the bottom base into cabins by using water stopping adhesive tapes; setting up a supporting system; lifting a prefabricated side wall by lifting equipment; plugging the outside edges of the joint surfaces on the bottom base and the joint surfaces on the prefabricated side wall to form sealed joints; grouting by grouting equipment; and other steps. By the method, a high-strength grouting material is adopted during grouting, so that the strength of the sealed joints can be improved, and the strength and the stability of the connecting node position of the bottom base and the prefabricated side wall are guaranteed. The method is convenient in construction, high in safety, short in construction period, low in cost and particular suitable for construction of an assembling integrated type subway station in a bad environment at relatively low air temperature and hi
