Construction method null of reinforcement earth laid

摘要

PURPOSE:To simplify the operations by arranging supporting members between self-supporting form materials and drainage material side in which planar reinforcing materials are wrapped, removing the supporting members after construction of a banking body, and placing concrete between the form materials and the drainage materials. CONSTITUTION:A pit is excavated to install form materials 1 such as concrete panels, etc., into it, and then refilled to make the form materials self-supporting. Next the supporting members are arranged on the banking-body construction side of the form materials 1 through wedges, drainage materials 6 are wrapped up in the end parts of planar reinforcing materials 5, and banking materials 7 are laid over the other parts to construct a banking body. Further, each time one layer of the banking is constructed, the wedges and the supporting members are removed to be used for constructing the upper stages of the banking. After the removal of the supporting members, concrete is placed between the form materials 1 and the drainage materials 6 to construct a body concrete 8. Thus, the need for reaction force at the time of concrete placing can be eliminated to simplify the work.
