| 摘 要： | 在滨海浅滩进行钻孔灌注桩施工时,能否应用海水配制泥浆、应用什么样的造浆材料和处理剂、泥浆指标的合理应用是钻孔灌注桩成功施工的重要因素。通过对几种造浆材料的比选,泥浆配比的优化,对使用海水配制膨润土泥浆的可行性进行了分析。结合首钢曹妃甸2号高炉区钻孔桩施工实例,简要介绍了膨润土海水泥浆的成功应用,对施工过程中的控制方法做了说明,以达到指导类似工程施工的目的。

| Abstract: | Whether to use the seawater to compound the slurry,what materials and treatment agent should be applied and the reasonable application of slurry indices are the important factors for bored grouting pile construction in coastal shoal.Through the comparison of several kinds of slurry material and the optimization of the slurry proportion,analysis was made on the feasibility of bentonite slurry compounded with seawater.With the construction case of bored pile in 2nd blast furnace in Caofeidian,the paper briefly introduced the successful application of bentonite seawater slurry and illustrated the construction control method. |
