PURPOSE:To make easier the construction work for protecting a slope as well as to shorten the period of construction work by a method in which form pipes to be freely assembled are set on a slope, and concrete or cement mortar is placed into the form pipes to construct a concrete structure. CONSTITUTION:A form pipe 1 assembled of an upper form 11 and a lower steel plate 14 is set on a slope B, an iron bar 2 is set inside the form pipe 1, and the form pipe 1 is fixed by anchors 3. Then, cement mortar or concrete 4 is placed into the form pipe 1 to construct a concrete structure C, and then the upper part of the form pipe 1 is removed. Also, proper numbers of holes 16 through which cement mortar or concrete 4 is flowed out are drilled in the lower steel plate 14. By this, the loosening of the ground in the initial period can be prevented and the safety of the construction work can be raised. |
