Wading bridge cofferdam integrated construction process
The invention provides an integrated construction process for a wading bridge cofferdam, and belongs to the field of building construction. According to the technical scheme, the construction method comprises the steps that S1, a construction shortcut is erected, S2, a lock catch steel pipe pile cofferdam, a Larsen IV steel sheet pile cofferdam and a water passing pipe culvert cofferdam are inserted and driven through the shortcut, a construction platform is erected, a Larsen VI steel sheet pile cofferdam is inserted and driven to form a mud pit, S3, an overwater temporary bridge is erected, S4, bridge pile foundation construction and drilling and pile forming are conducted on the construction platform, S5, a foundation pit is backfilled, and the lock catch steel pipe pile cofferdams are dismantled. S6, in other construction stages of the bridge, after construction of a bent cap on the upper portion of the bridge is completed, the construction platform and the water passing pipe culvert are dismantled, and a staggered lane is reserved; S7, a construction shortcut is dismantled, and silt on the upper portion of the opposite-pulling support is returned to a river channel through an excavator; and dismantling the opposite-pulling support. The construction method has the beneficial effects that the foundation pit, the construction platform, the shortcut and the mud pit are in close contact and exchange with the riverway through the steel cofferdam, and pollution to the riverway in the construction process is avoided.
本发明提供了一种涉水桥梁围堰一体化施工工艺，属于建筑施工领域。其技术方案为：S1、搭设施工便道，S2、利用便道插打锁扣钢管桩围堰、拉森IV钢板桩围堰、过水管涵围堰，并搭设施工平台，插打拉森VI钢板桩围堰形成泥浆池，S3、搭设水上便桥，S4、在施工平台上，桥梁桩基础施工，钻孔成桩，S5、回填基坑，拆除锁扣钢管桩围堰，S6、桥梁其他施工阶段，待桥梁上部盖梁施工完成后拆除施工平台和过水管涵，留下错车道，S7、拆除施工便道，将对拉支撑上部的泥沙采用挖机还至河道；拆除对拉支撑。本发明的有益效果为：通过钢围堰将基坑、施工平台、便道和泥浆池与河道紧密接触和交换，避免施工过程中对河道的污染。
