Complex interactive silt geology steel sheet pile cofferdam and construction method
The invention relates to a complex interactive silty geology steel sheet pile cofferdam and a construction method, and adopts an enclosing purlin integral assembly reverse construction installation technology, a vertical guide frame is arranged on a steel casing to assist in hanging and placing enclosing purlins, and a double-layer adjustable steel guide frame device is arranged by means of the enclosing purlins to serve as a steel sheet pile guide frame. According to complex ground conditions, steel jackets are introduced to replace steel sheet piles, a combined cofferdam of the steel jackets and the steel sheet piles is formed, the steel cofferdam inner support firstly-supporting and then-pumping technology is further adopted, the stability of the steel sheet piles is improved, and meanwhile an integral drainage pipe network, an assembly type drainage ditch, a prefabricated steel water tank used for centralizing accumulated water and the like are arranged for multi-dimensional drainage. The construction method has the advantages of being high in construction efficiency, good in water stopping effect and not prone to deformation, the stability and bearing capacity of the steel sheet pile cofferdam can be improved, and good technical and economic benefits can be obtained when the construction method is applied to actual engineering.
本发明涉及一种复杂交互粉砂地质钢板桩围堰及施工方法，采用围檩整体拼装逆作安装技术，在钢护筒上设置竖向导向架辅助吊放围檩，借助围檩设置双层可调节钢导框装置作为钢板桩导向架。针对复杂地况引入钢套箱代替钢板桩，形成钢套箱于钢板桩的组合围堰，进一步采用钢围堰内支撑先撑后抽技术，提高钢板桩稳定性，同时设置整体式排水管网、装配式排水沟及用于集中积水的预制钢水箱等进行多维排水，利用钢护筒支撑+吊挂组合搭设封底混凝土施工平台，本发明具有施工效率高、止水效果好、不易变形的优点，能够提高钢板桩围堰稳定性和承载力，应用于实际工程中可取得较好的技术经济效益。
