一、工程概述倚宿橡胶坝位于江苏省邳县邳苍分洪道倚宿庄附近,是邳苍分洪道西偏泓治理工程的主要项目之一。主要设计数据为:橡胶坝按五年一遇排涝流量Q=900m~3/s设计,上游河底高程▽23.0m,底宽93m边坡1:3,下游河底高程▽21.0m。选用楔块挤压双锚固枕式橡胶坝,坝袋长92.4m,高2.5m,上弧长4.39m,下弧长4.43m,内外压比α=1.3,袋壁环向拉力2.5t/m,单宽容积10.75m~3,坝袋底板高程▽23.5m,蓄水位▽25.0m。西端设泵房充水,安装12HBC_2-40混流泵二台套(其中一台备用),通过八个闸阀控制充排水。岸墙与泵房间充水管上加设安全溢流管,出口高程26.75m(图1)。
I. Overview of the Project The Leaning Susane rubber dam is located in the vicinity of Yingcangzhuang, Sucongfengyuan Road, Juxian County, Jiangsu Province and is one of the major projects of West Wanghong Regulation Project of Sucun Sub-normalization Project. The main design data are as follows: The rubber dam is designed according to the drainage flow Q = 900m ~ 3 / s once in five years. The upstream river bottom elevation is 23.0m, the bottom width is 93m, the slope is 1: 3 and the downstream river bottom elevation is 21.0m. The choice of wedge extrusion double anchorage pillow rubber dam, dam bag length 92.4m, height 2.5m, the arc length of 4.39m, the arc length of 4.43m, internal and external pressure ratio α = 1.3, bag wall circumferential pulling force 2.5t / m , Single width of 10.75m ~ 3, dam bag floor elevation ▽ 23.5m, water level ▽ 25.0m. Set the western end of the pump room filled with water, the installation of 12HBC_2-40 two sets of mixed flow pump (one of the spare), through the eight gate valve control drainage. The bank and the pump room filled with safety overflow pipe overflow, exit elevation 26.75m (Figure 1).
