Trolley steel end mold for cingulum waterstop positioning and secondary lining construction method

The invention discloses a trolley steel end mold for cingulum waterstop positioning and a secondary lining construction method. The trolley steel end mold comprises a plurality of sets of arc steel mold plates. The multiple sets of arc steel mold plates form the trolley steel end mold with the same shape as the section of a constructed tunnel, a sealing layer for sealing is arranged between the trolley steel end mold and a preliminary bracing structure, and the thickness of the sealing layer is smaller than the distance between the outer edge of the steel end mold and the preliminary bracing structure. The construction method comprises the following steps of 1 placing a trolley in place, 2 installing and positioning a cingulum waterstop, 3 installing the sealing layer, 4 pouring concrete and 5 removing the mold. The trolley steel end mold is simple in structure and convenient to operate, and the input cost is small; construction steps are simple; the using effect is good, and the practical value is high; the
