Description

本発明は、自由勾配側溝すなわち、コンクリート製門型側溝ブロックを使用して、勾配を設けるか又は平坦な設置面を形成した道路側面等へ容易に側溝を形成する門型側溝の施工法及びそれに用いる高さ調整金具に関する。   The present invention relates to a method of constructing a gutter-type side gutter that uses a free-gradient gutter, that is, a concrete gutter-type gutter block, to easily form a gutter on a road side or the like on which a slope is provided or a flat installation surface is formed. It is related with the height adjustment metal fitting to be used.

図６に従来の門型側溝の施工法の概要を示したが、（a）施工面１の掘削、基面整正した上に、（b）基礎砕石２を敷き均し、転圧して基礎を整え（基礎整地）、（c）その上へ基礎型枠３組付けをして、（d）これにモルタルを打設して、まず、基礎コンクリート４を形成する。この基礎コンクリートが数日かかって養生を終えた段階で、（e）門型側溝ブロック５を設置し、楔片６で高さ調整をし、底版コンクリート７を打設して施工を完了していた。楔片による高さ調整の難しさを解消するものとしては、特許文献１に門型側溝ブロックの両側下縁部を短冊状の支持プレート上へ載せ、垂直方向の高低調整ボルトにより門型側溝ブロックを最適な高さへ維持し、その状態で門型側溝ブロック下縁とベースコンクリート間に支持部材を詰める施工法が提案されている。この施工法は門型側溝ブロック下縁外側で高低調整ボルトを調節する必要があることから、施工面の掘削もそれだけ多く必要とするため、上部の溝蓋穴から調節する構造についても提案されている（特許文献２）。   Fig. 6 shows the outline of the conventional method for constructing the portal gutter. (A) After excavating the ground surface 1 and adjusting the ground surface, (b) laying the ground crushed stone 2 and leveling it, rolling it to the foundation (C) The foundation mold 3 is assembled thereon, (d) Mortar is placed on this, and the foundation concrete 4 is first formed. When the foundation concrete has been cured for several days, (e) the gate-type side gutter block 5 is installed, the height is adjusted with the wedge piece 6, and the bottom slab concrete 7 is cast to complete the construction. It was. In order to eliminate the difficulty in adjusting the height by the wedge piece, Patent Document 1 discloses that the lower side edges of the gate-type side groove block are placed on a strip-like support plate, and the vertical side-height adjustment bolt is used to mount the gate-type side groove block. A construction method has been proposed in which the support member is packed between the bottom edge of the gate-type side groove block and the base concrete in such a state. This construction method requires the adjustment of the height adjustment bolt outside the lower edge of the gate-type side groove block, so it requires more excavation of the construction surface, so a structure that adjusts from the upper groove cover hole has also been proposed. (Patent Document 2).
