Large-diameter high-grade reinforced concrete pile foundation pile cutting method and application
The invention belongs to the technical field of pile foundation concrete pile cutting, and discloses a large-diameter high-grade reinforced concrete pile foundation pile cutting method and application. The method comprises the steps that reinforcement wrapping is reserved in the pile cutting range; weakening the concrete strength in the pile cutting range of the pile foundation, namely weakening the strength of the concrete in the pile cutting depth range after the concrete is poured into the pile foundation; after the pile foundation concrete reaches 28 days, excavating the periphery of a pile head; pile cutting construction is conducted on the pile cutting portion of the pile foundation with the strength weakened; and waste slag treatment for chiseling away the pile foundation concrete is carried out. The pile cutting and slag discarding procedures are environmentally friendly and convenient, damage to reserved steel bars of a pile foundation in the pile cutting process is prevented, and the pile cutting quality is effectively guaranteed. By applying the technology, the defects in the prior art are effectively overcome, and high quality, high efficiency, energy conservation and environmental protection of large-pile-diameter high-grade concrete pile foundation pile cutting construction are achieved.
本发明属于桩基混凝土截桩技术领域，公开了一种大直径高标号钢筋砼桩基截桩方法及应用。该方法包括：截桩范围预留钢筋包裹；桩基截桩范围砼强度的弱化，在桩基浇筑混凝土完成后对截桩深度范围的砼进行强度弱化；桩基砼达到28天后，桩头周边开挖；对强度弱化后的桩基截桩部位进行截桩施工；凿除桩基砼的弃渣处理。本发明达到了截桩与弃渣工序环保、便捷，防止了截桩过程对桩基预留钢筋的损坏，有效保证了截桩质量。该技术的应用，有效解决了现有技术不足，实现了大桩径高标号砼桩基截桩施工的优质、高效与节能环保。
