滹沱河流域砂砾填筑路基施工技术

The construction technology of Hutuo river basin sand and gravel reclaimed roadbed

针对滹沱河流域土地资源匮乏,河内取砂筛余砂砾供应量大的现实,路基采用砂砾填筑、黏土包边的施工工艺,阐述了包边土、砂砾的原材料要求,及砂砾填筑路基的施工工艺,进行了一系列室内外试验,取得了良好的经济和环境效益。

Aiming at the status that the Hutuo river basin earth resource scarcity, river sand and gravel supplement large, the sand and gravel reclaimed and clay wrapping construction technology was adopted in roadbed, the wrapping earth and sand primary material requirement, sand and gravel reclaimed roadbed construction process was illustrated, a series of interior and exterior experiment was carried out, the better economic and environmental efficiency was obtained.
