To provide a driftwood capture structure, which can be constructed quickly by eliminating use of cast concrete at the site, is excellent at workability, economical efficiency, and flexibility (variability), and suitable for emergency measures and small mountain streams.SOLUTION: Multiple driftwood capture units 3 including a base material 1 extending in the flow direction of the river and a driftwood capture pillar 2 rising from the base material 1 and capturing driftwood are provided in the width direction of the river, adjacent driftwood capture units 3 are connected to each other by a horizontal connecting member 4 and a weight support pillar member 5 is erected on the base material 1 and/or the horizontal connecting member 4 located upstream of the driftwood capture pillar 2. A concrete block 8 (weight) is hooked on the weight support pillar member 5. On the concrete block 8 is formed a through hole, and is hooked to the weight support pillar member 5 in a skewered manner by using the through hole.SELECTED DRAWING: Figure 3
【課題】現場における打設コンクリートを無用化することにより迅速に構築することができる等、施工性、経済性、及び柔軟性（自在性）に優れ、緊急対策工や小規模渓流に好適な流木捕捉工を提供する。【解決手段】河川の流れ方向に延びる基材１と、前記基材１から立ち上がり流木を捕捉する流木捕捉柱２とからなる流木捕捉ユニット３が河川の幅方向に複数設けられ、隣り合う前記流木捕捉ユニット３同士が横繋ぎ材４で連結され、前記流木捕捉柱２よりも上流側に位置する前記基材１及び／又は前記横繋ぎ材４に錘支持柱材５が立設されてなる。前記錘支持柱材５に、コンクリートブロック８（錘）が掛け止められている。前記コンクリートブロック８は貫通孔が形成されており、前記貫通孔を利用して前記錘支持柱材５に串刺し状に掛け止められている。【選択図】図３
