止めている。Fig. 1 shows a cross section of the construction state corresponding to the construction process of the present invention, and the construction procedure will be explained below in conjunction with this drawing. A plywood veneer form 1 is erected inside the structure, an asphalt-impregnated molded board 2 is erected at a position separated from this plywood veneer form 1 by the required wall thickness, and these plywood veneer form 1 and asphalt are erected. Separator 3 between impregnated molded plate 2
are passed, and a vertical edge 4 and a horizontal edge 5 are passed to the outer ends of the separator 3, respectively, and these vertical edge 4 and horizontal edge 5 are fastened with form ties 6 screwed into both ends of the separator 3. .

設する。That is, the asphalt-impregnated molded plate 2 also serves as an outer formwork. However, if it seems that the asphalt-impregnated molded board 2 will not be able to withstand the lateral pressure of the poured concrete by simply pressing it with the vertical end thickness 4 and the horizontal end thickness 5, a plywood veneer formwork may be placed on the outside of the asphalt-impregnated molded board 2. Needless to say. Here, before the asphalt-impregnated molded board 2 is erected, a polymer cement slurry 7 is preliminarily applied to the inner surface when the asphalt-impregnated molded board 2 is erected.
Apply it. The asphalt-impregnated molded board 2 is installed with the surface coated with the polymer cement slurry 7 facing inside. In this way, the plywood veneer formwork 1 is installed inside what will become the outer wall of the underground structure, and the asphalt-impregnated molded board 2 coated with polymer cement slurry 7 is erected on the outside. 8.

When asphalt-impregnated molded boards are erected, polymer cement slurry has good compatibility with concrete and also with asphalt-impregnated molded boards, so it can be used as an adhesion enhancer between poured concrete and asphalt-impregnated molded boards. The asphalt-impregnated molded plate is firmly and integrally attached to the poured concrete, and after demolding, a waterproof layer can be formed on the surface of the asphalt-impregnated molded plate, eliminating the need to wait for the poured concrete to dry. This has the effect of significantly shortening the construction period. Furthermore, if an asphalt-impregnated molded board is used as a substitute for the plywood formwork, it becomes unnecessary to dismantle the outer formwork, which has the effect of further promoting labor savings and shortening the construction period. Furthermore, conventionally, unevenness on the surface of poured concrete was corrected before constructing the waterproof layer, but such repair work is no longer necessary, and the construction period can also be shortened from this point of view. The base of the last waterproof layer formed on the surface of the outermost layer is an asphalt-impregnated molded board, so the adhesion between the waterproof layer and the base is enhanced,
A highly reliable waterproof layer can be obtained.
