Expansion construction method for urban rainwater box culvert
The invention relates to an expansion construction method for an urban rainwater box culvert, which comprises the following steps of: expanding a new box culvert on one side of an old box culvert, arranging a foundation pit cross brace on the side wall of the old box culvert, and arranging a guide brace in the old box culvert to keep the stress balance of the side wall of the old box culvert; in the construction process of the newly-built box culvert, an expanded blade foot is poured between a bottom plate of the newly-built box culvert and a foundation pit supporting steel sheet pile, medium-coarse sand is backfilled between a side plate of the newly-built box culvert and the steel sheet pile, and it is guaranteed that a foundation pit supporting system is stable after a cross brace is dismantled. The construction cost is low, the influence on underground pipelines is small, the old box culvert can be prevented from being damaged, and the construction safety is guaranteed.
本发明涉及一种城市雨水箱涵扩容施工方法，在旧箱涵一侧扩建新箱涵，利用旧箱涵侧壁设置基坑横撑，并在旧箱涵内设置导撑保持旧箱涵侧壁受力平衡；新建箱涵施工过程中，在新建箱涵底板与基坑支护钢板桩间浇筑扩大刃脚，并在新建箱涵侧板与钢板桩间回填中粗砂，保证横撑拆除后基坑支护系统稳定。本发明施工成本低，对地下管线影响小，能避免旧箱涵受到损伤，并保证施工安全。
