龙江海口特大桥钻孔桩海水造浆施工技术

Long-distance sand-blowing technology for complicated working site

龙江入海口处海口特大桥的钻孔桩在施工过程中出现因直接采用该处海水造浆导致孔底沉渣达不到相关要求而对工程进度及成本造成影响的情况,通过对该处水质进行分析并经过试验室进行一系列的对比试验,对使用该水域水源直接配制的泥浆进行改良后形成符合该施工项目的泥浆配比。

Longjiang river of haikou extra large bridge bored pile in construction process caused by directly using it the sea mud making dreg deposited at the bottom of the hole can not meet the requirements for the situation of the construction schedule and cost impact, through the analysis of water quality there and after laboratory through a series of contrast experiments, mix the fluid water directly using the waters for mud formula of modified form conforms to the construction project.
