STEEL SLIT DAM
To provide a steel slit dam excellent in economy, quality, and maintainability by realizing a structure in which, when earth and stone, driftwood, etc., overflow a top of a slit structure, overflowing earth and stone, driftwood, etc., do not collide with a downstream post and a structure in which breakage of some members does not lead to breakage of a slit structure, thereby the whole of non-overflow portions (a dam, an embankment body).SOLUTION: In a steel slit dam, slit structures constructed three-dimensionally by connecting upstream column materials and downstream column materials with connecting materials are installed on a foundation portion between non-overflow portions constructed in a transverse direction of a river. The downstream column materials are provided in a posture rising in a vertical direction from the foundation portion. The slit structure comprises a protruding member that protrudes from an upstream column material and/or a downstream column material located at both ends in the transverse direction of the river to the non-overflow portion. The protruding member is supported by the non-overflow portion so as to be able to transmit stress.SELECTED DRAWING: Figure 1
【課題】土石や流木等がスリット構造体の頂部を越流する場合、越流した土石や流木等が下流側支柱に衝突しない構造であり、かつ、一部の部材の破損がスリット構造体、ひいては非越流部（堰堤、堤体）全体の破損につながらない構造を実現することにより、経済性、品質性、およびメンテナンス性に優れた鋼製スリットダムを提供する。【解決手段】上流側柱材と下流側柱材とを繋ぎ材でつないで立体的に構築されるスリット構造体を、河川の横断方向に構築した非越流部間の基礎部に設置してなる鋼製スリットダムにおいて、前記下流側柱材は、前記基礎部から鉛直方向に立ち上がる姿勢で設けられていること、前記スリット構造体は、河川の横断方向の両端部に位置する上流側柱材及び／又は下流側柱材から非越流部へ突き出す突出部材を備えており、前記突出部材が前記非越流部に応力伝達可能に支持されている。【選択図】図１
