摘 要:为突破当前碾压混凝土压实厚度只有30cm左右的限制,推动碾压混凝土施工技术的发展,引进国外新型垂直碾压设备和深层压实度检测仪器,通过两次生产性试验,对检测仪器进行改进,确定了60cm厚层混凝土碾压工艺,并成功应用于110m高碾压混凝土双曲拱坝局部坝段。
Abstract:The compaction thickness limit of the RCC is only 30cm at present. For breaking the thickness limit and promoting the development of RCC construction technology, the new vertical rolling equipment and deep compaction testing instruments are introduced from abroad. By doing the productive tests twice, the detecting instrument is improved, and concrete compaction technology for the 60cm compaction thickness is determined. The technology has successfully applied in the local dam section of 110m high roller compacted concrete hyperbolic arch dam.
