Combined steel sheet pile cofferdam and construction method
The invention relates to the technical field of bridge engineering, and discloses a combined steel sheet pile cofferdam and a construction method. The combined steel sheet pile cofferdam comprises steel sheet piles and steel pipe piles, wherein the steel sheet piles and the steel pipe piles are connected in a lock catch fit mode, a steel enclosing purlin is installed on the first steel pipe pile, a supporting mechanism is arranged in the steel enclosing purlin, a lifting type water pumping system is installed on the steel enclosing purlin, and arc-dragging detachable inner supporting frame reinforcing structures are arranged at the end parts of the first steel pipe pile and the second steel pipe pile. The construction method comprises the following steps of prefabricating and installing the steel pipe piles, the steel sheet piles and a guide device, inserting and driving a steel protection cylinder, filling sand, hoisting, inserting, driving and folding the steel pipe piles and the steel sheet piles, installing the steel enclosing purlin and the supporting mechanism, pumping water in a cofferdam foundation pit, and installing the second steel enclosing purlin and the third steel enclosing purlin. According to the combined steel sheet pile cofferdam and the construction method, the problems existing in the construction of an existing steel sheet pile cofferdam are effectively solved, the construction process is simple, the construction efficiency is well improved, and good technical and economic benefits can be obtained when the combined steel sheet pile cofferdam and the construction method are applied to practical engineering.
本发明涉及桥梁工程技术领域，且公开了一种组合式钢板桩围堰及施工方法，组合式钢板桩围堰包括钢板桩和钢管桩，钢板桩和钢管桩之间锁扣配合相连，第一钢管桩上安装有钢围檩，钢围檩内设置有支撑机构，且钢围檩上安装有可升降式抽水系统，第一钢管桩和第二钢管桩的端部均设置有弧拖可拆式内撑架加固结构，施工的步骤为：预制钢管桩、钢板桩和导向装置并安装、插打钢护筒、填砂、钢管桩和钢板桩的吊运插打与合拢、钢围檩及支撑机构的安装、围堰基坑内抽水，以及第二和第三道钢围檩的安装。本发明有效解决了现有钢板桩围堰施工存在的问题，施工过程较简单，较好的提高了施工效率，应用于实际工程中可取得较好的技术经济效益。
