PURPOSE: A foundation ground construction method of a concrete water channel pipe is provided to stably maintain a concrete water channel pipe by preventing a differential settlement etc. because a foundation ground of the concrete water channel is constructed on a uniform sand layer placed on a concrete mortal layer. CONSTITUTION: A foundation ground construction method of a concrete water channel pipe is as follows. Horizontal guide member(20) is installed in both sides of a longitudinal direction of the excavated ground to be horizontally balanced. Concrete mortal is placed inside of the horizontal member. A push bar(30) is transferred to longitudinal direction of the horizontal member to be adhered to both sides of the horizontal member so that the concrete mortar is horizontally balanced. Sand is placed on the upper part of the concrete mortar. The push bar having a space retainer(32) is transferred to a longitudinal direction of the horizontal member in the both upper sides of the horizontal member so that a sand layer is horizontally balanced. |
