金峰水库极软砂岩筑坝施工技术
|
摘要
金峰水库为四川省武都引水灌区工程的一座囤蓄水库,大坝为沥青混凝土心墙石渣坝,坝体石渣料为极软砂岩。通过现场碾压试验,对极软砂岩作为筑坝材料进行了深入研究,确定了合理的施工参数和施工质量检测评价指标。实际施工严格按照施工参数进行,经现场质量检测,施工质量满足设计要求。
Jinfeng Reservoir is a storage reservoir of Wudu Irrigation District Project in Sichuan Province. The dam is a gravel dam with asphalt concrete core wall, and the dam body gravel material is extreme soft sandstone. The extreme soft sandstone as dam body filling material is studied by on-site rolling tests, and reasonable construction parameters and construction quality inspection and evaluation index are determined. The actual dam filling is conducted in strict accordance with construction parameters, and on-site quality inspection shows that the construction quality meets design requirements.
