摘要

填砾式结构作为一种比较先进的钻孔结构,自运用到我国地浸生产钻孔以来,其施工技术已相对成熟,施工工艺也从静水填砾发展到动水填砾,特别是动水上升流填砾工艺已广泛得到应用,在大量实践中积累了丰富经验,使填砾式钻孔结构的施工工艺进一步完善。
The gravel filling,taken as a relative advanced technology of drilling hole configuration,is comparatively mature at completion since application in China for drilling hole construction of in-situ leaching.Its technique of construction has developed from static water gravel filling to flow water gravel filling.In particular the upflow gravel filling of flow water has been widely used.Abundant experiences are accumulated in quite amount of practices,so the completion technology of gravel filling has further been improved.
