前言三河闸是淮河入江水道的总口门,共63孔,全长697.75m,设计流量12000m~3/s.自1953年建成后,配合洪泽湖周边其它工程,对洪泽湖排水、蓄水灌溉、城市供水及改善淮河中下游航道条件等方面发挥了巨大的作用。三河闸闸门为弧形闸门,侧止水装置原设计为木止水,1968年加固时改为橡胶水封,配用混凝土止水座板.该止水座板经过20多年的运行,出现表面剥落、掉边缺角、糙度加大等现象,难以达到止水装置的预期效果,急需修复。
Preface Sanhe sluice is the total port of Huaihe River waterway with a total length of 697.75m and a designed flow rate of 12000m ~ 3 / s since the completion of the project in 1953. In cooperation with other projects around Hongzehu Lake, it drains Hongze Lake Water irrigation, urban water supply and improve the middle and lower reaches of the Huaihe River channel conditions have played a huge role. Sanhe gate for the arc gate, the side of the water stop device was originally designed to stop the water, when the reinforcement in 1968 to rubber seal, equipped with concrete water stop seat after the water stop the seat after 20 years of operation, there surface Peeling off, missing corner missing, increased roughness and other phenomena, it is difficult to achieve the expected effect of stop devices, urgent need to repair.
