1 引言 黄墩湖滞洪闸位于江苏省徐州、宿迁两市交界处、中运河西堤堤后的滩地上,距民便河船闸中心以南300m。闸上游与中运河相接,闸下游为邳洪河、民便船闸引航道的交汇处。 由于沂、沭、泗洪水峰高量大,骆马湖调蓄库容有限,当骆马湖遭遇较大的洪水时,需利用黄墩湖地区滞洪削峰,以确保骆马湖控制安全。黄墩湖滞洪区面积为335km~2,涉及徐州、宿迁两市2.07万hm~2耕地,最大滞洪库容14.7亿m~3,黄墩湖滞洪闸作为滞洪区的主要控制建筑物,是保证滞洪时22.2万人口安全撤离的关键工程。
1 INTRODUCTION The floodgate at Huangdun Lake is located 300 meters to the south of Mintika River Ship Lock Center on the beach after the embankment of the middle canal in Xuzhou and Suqian of Jiangsu Province. The upper reaches of the gate connect with the middle canal, and the lower reaches of the gate lead to the confluence of the Huangdao River and the Minhui Lock. Due to the large quantity of Yishu, Shu and Sihong peaks, the storage capacity of Luoma Lake is limited. When Luoma Lake encounters a large flood, it is necessary to use the flood arrest in Huangdun Lake to ensure the safety of Luoma Lake. Huangdun Lake flood detention area of 335km ~ 2, involving Xuzhou, Suqian 20,700 hm ~ 2 of cultivated land, the maximum detention flood storage capacity of 1.47 billion m ~ 3, Yellow Dam Floodgate as the main control building detention area, is to ensure that detention The key project for the safe evacuation of 222,000 people.
