Casting template device for turnover drainage ditch

A pouring formwork device for a turnover type drainage ditch comprises a lifting rod (3) used for stretching across a foundation trench of the drainage ditch, an outer side panel set arranged at the end of the lifting rod (3) and an inner side panel set arranged on the middle portion of the lifting rod (3), and through rod connection of the outer side panel set and the inner side panel set is achieved through the lifting rod (3). By means of the outer side panel set and the inner side panel set, the pouring interval of the inner wall of the drainage ditch is arranged, and formwork components of the pouring interval of the inner wall of the drainage ditch are integrally installed in a segmented mode; the technical problem that the two side face pouring formworks need to be independently installed due to the fact that the two side face pouring formworks are installed on the side face of the drainage ditch foundation trench through the stand columns and the transverse rods is solved, and therefore the installati
