PROBLEM TO BE SOLVED: To effectively suppress rain from falling into a concrete form when an annular concrete wall is constructed by using a method implemented while the concrete form is elevated as casting of concrete is advanced.SOLUTION: There is provided a rainproof device 100 for elevation type concrete form installed in a slip form device 10 which elevates a pair of inner and outer concrete forms 11, 12 for constructing an annular concrete wall and inner and outer upper-stage scaffolds 27, 28 arranged above the concrete forms 11, 12 as casting of concrete is advanced. The rainproof device elevation type concrete form includes a roof 110 on an inner peripheral side supported by the inner upper-stage scaffold 27 to tilt to an outer peripheral side, and a roof 120 on the outer peripheral side supported by the outer upper-stage scaffold 28 to tilt to the inner peripheral side. |
