PURPOSE:To easily perform the spraying work of cement mortar on a slope by a method in which formworks of a water-resistant corrugated cardboard are set on a place to be sprayed with cement mortar of the slope, iron bars are set in the formworks, and then cement mortar is sprayed. CONSTITUTION:Iron bars 22 are fixed to a bolt 21 fixed to a slope, and a formwork fitting lever 23 is attached to the bolt 21 or the iron bars 22. The formwork plates 1 of a water-resistant corrugated cardboard are connected with hook pins 4 in such a way as to surround the iron bars 22 to form a formwork (a). The formwork (a) is matched with the inclined angle and uneven surface of the slope by turning the formwork plates 1 around the pin 4 or sliding them in the long hole 3, the fitting lever 23 is projected from the formwork plate 1, the nut 25 is screwed with the threaded portion 24, and the formwork (a) is fixed to the slope. Cement mortar is then sprayed into the formwork (a) to form a sprayed layer (b), and cement mortar is further sprayed onto the surrounding of the formwork (a). |
