1 工程概况 王庄闸枢纽工程位于新沂市境内的总沭河上,设计过水流量3000m~3/s,闸基础为砂性土。该闸总宽400m,每孔净宽8m,双层结构,洞顶为节制闸,底部为双孔箱式涵洞,共45孔,其中1孔为发电孔、2孔为直升门,其余42孔为自动翻板门。 由于该工程年久失修,老化严重,加上闸下河床逐年下切,闸下游护坦末端河底已下降4m多,每年汛情都出现程度不同的险情,成为新沂
1 Project Overview Wangzhuang brake hub project is located in the territory of Xinyi City, the total River, the design flow of 3000m ~ 3 / s, sluice foundation for the sand. The gate has a total width of 400m and a net width of 8m each. The double-deck structure has a top hole for the control gate and a double-hole box culvert at the bottom for a total of 45 holes, of which 1 hole is a power hole, 2 holes is a helicopter, and the remaining 42 holes are Automatic flap door. Due to the long-term disrepair of the project and serious aging, coupled with the riverbed under the gates being cut down year by year, the bottom of embankments at the lower reaches of the gates has been reduced by more than 4m. As a result, dangerous situations of varying degrees occur each year in the flood season and become Xinyi
