CONSTRUCTION METHOD OF HEADRACE CHANNEL OF DAM AND HEADRACE CHANNEL OF DAM
To provide a construction method of a headrace channel of a dam and a headrace channel of a dam allowing construction period for the headrace channel of the dam to be reduced.SOLUTION: A construction method of a headrace channel of a dam comprises: an improved soil structural body construction process of constructing an improved soil structural body 30 by piling up improved soil including solidification material along a natural ground tilting surface of a downstream of a dam body 2; a concrete block arranging process of arranging precast concrete blocks 10 in such a manner that front surfaces 10a of the concrete blocks 10 face the headrace channel area; and a concrete placing process of placing concrete with slump between the improved soil structural body 30 and rear surfaces 10b of the concrete blocks 10.SELECTED DRAWING: Figure 6
【課題】ダム導水路の構築に要する期間を短縮する。【解決手段】ダム導水路の構築方法は、固化材を含む改良土を堤体２よりも下流の地山斜面に沿って盛立てて改良土構造体３０を造成する改良土構造体造成工程と、プレキャスト製のコンクリートブロック１０を、コンクリートブロック１０の前面１０ａが導水路領域に臨むように配置するコンクリートブロック配置工程と、改良土構造体３０とコンクリートブロック１０の背面１０ｂとの間に有スランプのコンクリートを打設するコンクリート打設工程と、を備える。【選択図】図６
