筑堤铁矿剥岩土碾压试验

The Rolling Experimentation of the Iron Ore Flake Rock

滦河迁安市区段防洪工程第三期工程A01标段采用天然级配铁矿剥岩土作为筑坝材料,如何控制施工填筑质量是关键。通过碾压试验,可以确定土料压实后是否能够达到设计压实干密度值;检查压实机械具的性能是否满足施工要求;选定合理的施工压实参数;确定有关质量的技术要求和检测方法。

The embankment is filled with the iron ore flaked rock in A01 segment of the flood control for Qian'an city area near the Luanhe River, how to control the construction quality is the key. Through this rolling experimentation, you can confirm the soil had been rolled whether or not achieve the design construction of dry density; check up the rolling machine whether or not satisfies the construction request; choose rational rolling parameter; confirm quality request and the checking means.
