Foundation pit fender post construction method
The invention discloses a foundation pit fender post construction method, which relates to the field of pile foundation construction technology, and comprises the following steps: step 1, foundation pit fender post construction: arranging a pile body of a foundation pit fender post in a soil body, forming a pre-tensioning hole along the length direction of the pile body, arranging a pre-tensioning rope in the pre-tensioning hole in a penetrating manner, and fixedly arranging the lower end of the pre-tensioning rope and the pile body; and secondly, prestress is applied to the pile body, the upper end of the pre-tensioning rope is drawn, and after the pre-tensioning rope is drawn to the set position, the upper end of the pre-tensioning rope is fixed to keep the prestress of the pre-tensioning rope. The foundation pit fender post has the effect of preventing the pile body of the foundation pit fender post from being bent, the capacity of the pile body for resisting lateral soil pressure is enhanced, deformation of the pile body can be effectively reduced, and foundation pit engineering safety is guaranteed.
本申请公开了一种基坑围护桩施工方法，涉及桩基施工技术的领域，其包括：步骤一，基坑围护桩施工，在土体内设置基坑围护桩的桩身，沿桩身的长度方向设置预拉孔，预拉孔内穿设有预拉绳索，预拉绳索的下端与桩身固定设置；步骤二：桩身施加预应力，对预拉绳索的上端进行拉拔，预拉绳索拉拔到设定位置后固定预拉绳索的上端来保持预拉绳索的预应力。本申请具有预防基坑围护桩的桩身弯曲的效果，增强桩身抵抗侧向土压力的能力，有能够有效减少桩身的变形，保障基坑工程安全。
