River closure construction method for river-crossing cast-in-place bridge support foundation
The invention discloses a river-crossing cast-in-place bridge support foundation river channel closure construction method which comprises the following steps: determining closure design flow and closure conditions according to average flow of a river channel in unit time; a construction shortcut is arranged, and river channel desilting and rock ballast embankment are conducted; stone ballast occupation is carried out behind the embankment; in the occupation construction period, the flow guide pipes are buried in the mode of excavation after filling; dressed stone closure is carried out at the closure gap of the river channel; and after closure is completed, backfilling and compacting are conducted to form a cushion layer, and river channel closure construction is completed. According to the scheme, the project construction cost can be saved; meanwhile, after the support is dismantled, the filling slag can be used as abutment back filler, is recycled, is material-saving and environment-friendly, and conforms to the current industrial policy. The social benefit is obvious, and the use value and the popularization prospect are wide.
本发明公开了一种跨河现浇桥梁支架基础河道截流施工方法，包括：根据河道单位时间内平均流量，确定截流设计流量并确定截流条件；布置施工便道并进行河道清淤和石渣戗堤；戗堤后进行石渣进占；在进占施工期间，采取填后开挖的方式埋设导流管；在河道龙口处进行料石截流合龙；截流合龙完成后进行回填压实形成垫层，完成河道截流施工。根据本发明的方案，可节约项目施工成本；施工范围适用广泛、能缩短工期、安全可靠、操作便捷的优点，同时，填渣在支架拆除后，可做台背填料，回收循环使用，节材环保，符合当前产业政策。社会效益显著，具有广阔的使用价值和推广前景。
