摘要
冲孔灌注桩在广西内河高桩码头建设中的应用较多,考虑到其混凝土灌注在水下进行,不易掌控,因此灌注技术成为了冲孔灌注桩施工的难点,需要引起施工管理者的高度重视,并应采取有效的技术手段与措施来防范灌注风险。文章以来宾港武宣港区龙从作业区一期工程为例,分析了内河高桩码头冲孔灌注桩施工中的灌注技术特点和施工工艺。
The punched cast-in-place piles are widely used in the construction of inland high-pile wharf in Guangxi,then,considering that its concrete pouring is carried out under water,with difficult control,thus the pouring technology has become a difficult point in the construction of punched cast-in-place piles,which requires more attention from the construction managers and taking the effective technical means and measures to prevent the pouring risk.With Phase I engineering of Longsong operation area in Wuxuan Port District of Laibin Port as the example,this article analyzes the characteristics and construction process of pouring technology in the construction of punched cast-in-place piles in inland river high-pile wharf.
