PURPOSE:To obtain the joints of an underground wall, having a capability to strongly connect elements, by providing an iron bar cage having a channeling member with dowels and an iron bar cage having diagonally crossed iron bars. CONSTITUTION:Discrete trenches C1 are excavated at intervals of one-span, an iron bar cage A having a channeling member 2 with dowels 5 is settled into the discrete trenches C1, and concrete is placed to form a discrete wall W1. After the completion of the discrete wall W1, an intermediate trench C is excavated between both the walls W1 and the iron bar cage B with diagonally crossed iron bars 6 is put down in the intermediate trench C. In this case, the diagonally crossed iron bars 6 of the cage B are positioned between the dowels 5 of the channeling member 2 already set under the ground in the previous process. After the erection of the iron bar cage B is finished, concrete is placed into the intermediate trench C to form new continuous wall to connect the discretely built walls W1 constructed in the previous process. |
