小溶江拦河坝为碾压砼重力坝,坝顶总长247m,坝顶宽7m,最大坝高89.5m。大坝坝体共分10个坝段,其中:溢流坝为一个坝段,采用实用堰结构;非溢流坝段共9个,设计为重力坝结构型式,采取前期通过随坝体升层同步填筑临时施工道路的方式利用自卸汽车直接运输碾压砼入仓,后期溢流表孔将坝体左、右岸非溢流坝段分割施工。
Small river dam for the RCC gravity dam, dam total length 247m, crest width 7m, the maximum dam height 89.5m. The dam body is divided into 10 dam sections, of which: the overflow dam is a dam section and adopts a practical weir structure; a total of 9 non-overflow dam sections are designed as a gravity dam structure type, The way to fill the temporary construction road at the same time is to use Dump Truck to transport roller compacted concrete directly into the warehouses. In the later stage, overflow spillway will be constructed by dividing the non-overflow dam sections on the left and right banks of the dam.
