Construction method for reducing sinking of steel sheet piles with piles and improving overall stability of foundation pit
The invention discloses a construction method for reducing sinking of steel sheet piles with piles and improving overall stability of a foundation pit. The method comprises the steps that a rope screwing connecting part is arranged at the set position of the top of each steel sheet pile to be constructed; a prefabricated gravity type anchor system is arranged at the safe position outside the construction range of the steel sheet piles; and the steel sheet piles are constructed in sequence, when each steel sheet pile is driven to the preset elevation, the rope screwing connecting part on the steel sheet pile is connected through a steel wire rope, and the other end of the steel wire rope is fixed to the prefabricated gravity type anchor system. The construction method is applied to protection of a retaining wall, a bridge building cofferdam, a foundation municipal engineering wading section and the like, and has the beneficial effects that operation is easy, the effect is obvious, the construction period is shortened, the engineering cost is reduced, safety and feasibility are achieved, and the quality is guaranteed; and deformation of the steel sheet piles in the steel sheet pile construction process can be greatly reduced, disturbance of a cofferdam soil body is reduced, the integrity and stability of the steel sheet piles are improved, the foundation pit construction safety is guaranteed, and the piling time is shortened.
本发明公开了一种减少钢板桩带桩下沉及提高基坑整体稳定性的施工方法，该方法包括：在每片待施打的钢板桩顶部设定位置处设置一个绳索旋拧连接部件；在钢板桩施工范围外安全位置设置预制重力式锚锭系统；按序施打各钢板桩，每片钢板桩打入至预定标高时，通过一根钢丝索连接该钢板桩上的绳索旋拧连接部件，该钢丝索的另一端固定于预制重力式锚锭系统。本发明应用于挡土墙、建桥围堰、基础市政工程涉水段防护等，具有操作简单、效果明显、缩短工期、降低工程造价、安全可行、质量有保证，能极大减少钢板桩施打过程中钢板桩变形，减少围堰土体的扰动，提高钢板桩的整体性和稳定性，保证基坑施工安全，缩短打桩时间。
