PROBLEM TO BE SOLVED: To provide a rational and economical steel slit dam, which does not require various works including those of breaking the concrete foundation and of re-constructing the same during replacing upstream-side column members which are most vulnerable to damage among steel frame members.SOLUTION: A steel slit dam in the present invention consists of a plurality of steel pipe frame members 10 which are vertically erected on a concrete foundation 11 and installed at intervals along the direction across a river. The steel pipe frame member 10 comprises: a downstream-side unit 1, which is composed by unifying a horizontal member 1a horizontally extending towards the upstream front of the concrete foundation 11 and a downstream-side column member 1b extending upwards from the concrete foundation 11; and an upstream-side unit 2, which consists of an upstream-side column member 2a fitted with joint members 2b and 2c which join respectively with projecting parts of the horizontal member 1a and the downstream-side column member 1b of the aforesaid downstream-side unit 1. The upstream-side unit 2 is joined in a detachable manner with the downstream-side unit 1 which is fixed on the aforesaid concrete foundation 11.SELECTED DRAWING: Figure 1
【課題】鋼管フレーム部材のうち最も損傷を受けやすい上流側の柱材を交換する際に、コンクリート基礎の破砕作業、およびコンクリート基礎の再打設作業等の各種作業を行う必要のない、合理的かつ経済的な鋼製スリットダムを提供する。【解決手段】コンクリート基礎１１に立設する構成の鋼管フレーム部材１０を河川横断方向に間隔をあけて複数設置してなる鋼製スリットダムであって、鋼管フレーム部材１０は、コンクリート基礎１１の上流側前方へ略水平に突出する水平材１ａと、同コンクリート基礎１１の上方へ突出する下流側柱材１ｂとを一体化してなる下流側ユニット１と、前記下流側ユニット１の水平材１ａおよび下流側柱材１ｂの突出端部とそれぞれ接合する接合部材２ｂ、２ｃを備えた上流側柱材２ａからなる上流側ユニット２とで構成され、前記コンクリート基礎１１に固定された下流側ユニット１に上流側ユニット２が脱着可能に接合されてなる。【選択図】図１
