Mounting assembly for waterproof roll shell nosing and waterproof structure of wall

The invention discloses a waterproof roll closing-up mounting assembly and a waterproof structure of a wall. According to the technical scheme, the installation assembly is adopted for installation needed when the waterproof coiled material is closed up, the installation assembly is provided with the step face, the step face and the wall body can form the notch used for containing the closed-up portion of the waterproof coiled material after the anchoring part is anchored into the wall body, and therefore it is guaranteed that the closed-up portion of the waterproof coiled material can be fully spread out; the bending area of the closing-up part is fully attached to the wall face, so that the phenomenon that closing-up folds are caused by insufficient spreading is eliminated, and the edge closing-up quality is improved. In addition, by adopting the installation assembly with the structure, the waterproof roll can be subjected to edge closing and then main body paving, the waterproof roll closing construction
