Cast-in-situ bored pile head cutting construction method
The invention discloses a cut-off construction method for a pile head of a cast-in-situ bored pile, and belongs to the technical field of foundation treatment engineering. The method is implemented through the four steps of measuring the depth of a broken pile, excavating a pit, drilling a hole, protecting a wall by slurry and splitting a pile head. According to the method, the stability and durability of the structure are kept on the premise of ensuring the safety in the pile head cutting construction of the cast-in-situ bored pile. According to the method, the pile head concrete and the main reinforcements are not wrapped, and after the foundation pit is excavated and the pile head is chiseled away, the stripping operation of the reinforcements and the concrete is not carried out, so that the pile head chiseling-away speed is greatly increased, and the construction cost is reduced. The investment of equipment and personnel is reduced, and the construction cost is saved; the method mainly can protect the local original ecological environment and ensure the body health of workers, has the characteristics of simple process, high controllability, high speed, no damage to the pile body and the pile body reinforcing steel bar, cost saving, no pollution and low noise, and obtains better effect and economic benefit.
本发明公开了一种钻孔灌注桩桩头截断施工方法，属于地基处理工程技术领域。本发明通过测出断桩深度、开挖凹坑、钻孔泥浆护壁、桩头劈裂这四个步骤予以实现。本发明在钻孔灌注桩桩头截断施工需要在确保安全的前提下，保持结构的稳定性和耐久性。本发明中桩头混凝土和主筋不发生握裹，在基坑开挖后，凿除桩头时，不进行钢筋和混凝土的剥离作业，从而大大加快桩头凿除速度，降低施工成本。本发明减少了设备人员的投入，节约了施工成本；主要是能保护当地原生态环境，保证了工人的身体健康，此方法具有工艺简易、可控制性强、速度快、对桩体及桩体钢筋无损伤、节约成本、无污染、噪音小的特点，取得了较好的效果和经济效益。
