Dry dock system for prefabricating inland river immersed tube and construction process thereof
The invention relates to a dry dock system for prefabricating an inland river immersed tube and a construction technology of the dry dock system, and belongs to the technical field of immersed tube tunnel construction. The dry dock system for prefabricating the inland river immersed tube comprises a dock bottom, and further comprises a supporting system, a water stopping system and a flood control system; the supporting system comprises a dock wall, a supporting protection slope on the periphery of the dock wall, a steel pipe pile wall at a dock entrance, first underground diaphragm walls at the two ends of the steel pipe pile wall and second underground diaphragm walls formed by extending the first underground diaphragm walls in the river channel direction. The water stopping system comprises a water stopping curtain, an anti-seepage wall at the dock entrance and a third underground diaphragm wall formed by extending the second underground diaphragm wall in the river channel direction. The flood control system comprises a temporary flood control cofferdam, a flood control wall and a flood control levee. According to the dry dock system, through combination of various structural forms, a reliable supporting system, a reliable water stopping system and a reliable flood control system are provided for the dry dock system, and the dry dock system can adapt to complex hydrogeological conditions, especially soft soil layers such as sludge and mucky soil which are common in inland river immersed tube tunnel engineering.
本发明涉及一种用于内河沉管预制的干坞系统及其施工工艺，属于沉管隧道施工技术领域。该用于内河沉管预制的干坞系统包括坞底，还包括支护体系、止水体系和防洪体系；其中，支护体系包括坞墙、坞墙外围的支护坡、坞口处的钢管桩墙和钢管桩墙两端的第一道地连墙，以及第一道地连墙沿河道方向延伸形成的第二道地连墙；止水体系包括止水帷幕、坞口处的防渗墙、第二道地连墙沿河道方向延伸形成的第三道地连墙；防洪体系包括临时防洪围堰、防洪墙和防洪大堤；该干坞系统通过多种结构形式的组合，为干坞系统提供了可靠的支护体系、止水体系和防洪体系，能够适应复杂的水文地质条件，尤其是内河沉管隧道工程中常见的淤泥、淤泥质土等软弱土层。
