水下预填骨料升浆混凝土的应用

摘要

Underwater prepacked aggregate concrete is generally used in construction of dock floor of large dock, water stopping works for dock walls and cofferdams for docks being built in wet, counterweight blocks in dock floors,improvement of foundation beds for gravity caissons,reinforcing rock-fill in caissons for heavy-duty wharfs and leakage stopping works in docks. Based on the summary and analysis of the actual results of related projects,the paper discusses the properties of under-water prepacked aggregate concrete and the problems to attend to during the construction,with a view to provide reference for the determination of design parameters, construction process control,quality acceptance standard for similar projects.%　　水下预填骨料升浆混凝土一般应用于大型船坞工程的船坞底板和湿法施工坞墙的止水工程、堵口围堰基床止水、船坞底板配重体、重力式沉箱基床加固、重载码头沉箱内块石整体强度的加固和局部堵洞等项目中。通过总结分析相关工程的实际效果，论述了水下预填骨料升浆混凝土的性能和施工应用中注意事项，以期为类似工程的设计技术指标的确定、施工工艺的控制、质量验收标准的评定等提供参考。
