Abstract

PURPOSE:To prevent the occurrence of voids in the joints of concrete by closely connecting the concrete to be placed by a method in which the bottom of a split wall is formed into a centrally heightened hump and concrete is poured through an inclined hole formed from the top of the centrally heightened mountain shape toward the inside. CONSTITUTION:The inside of an underground wall 10 is excavated, and a formwork 13 consisting of a bottom plate 11 and inside plates 12 is fabricated. Then, iron bars are arranged in the space formed by the formwork 13 and the underground wall 10 and on the periphery of pipes 15 and concrete is placed to form a split wall 16a for the first lot. Furthermore, excavation is performed, the formwork for the first lot split wall 16a is removed, the second lot formwork 13 is fabricated under the split wall 16a, and then concrete is placed. Laitance 17 goes up along the inclined face of a mountain-shaped portion 14 and gathers in the hole 15a, so that the corresponding supplement of concrete from the inside of the hole 15a is naturally made. The laitance staying on the upper part of the hole 15a is removed, concrete is supplied to fill up the hole 15a, and the placement of concrete for the second lot split wall 16b is completed.
