Soft soil area bridge cast-in-place pile construction method
The invention relates to the technical field of bridge engineering construction, and discloses a soft soil area bridge cast-in-place pile construction method which solves the technical problem of how to conduct secondary construction technical correction on safety problems caused by inclination in the prior art, and the soft soil area bridge cast-in-place pile construction method comprises the steps that firstly, a foundation pit is excavated, specifically, the foundation pit is excavated to the pile bottom of an inclined pile foundation; 2, measuring the pile position of the inclined pile foundation: determining the inclination direction and angle of the inclined pile foundation; thirdly, deep soil taking and pressure relief are conducted; fourthly, a pile foundation deviation rectifying mold body is installed; fifthly, the foundation pit is poured, and a deviation rectifying pile is formed; 6, gap backfilling treatment is conducted, specifically, after deviation rectifying and pouring are conducted, gaps may appear on the other inclined side, and the gaps are tamped compactly after backfilling sand or soil-included sand is poured; seventhly, the deviation rectifying pile is maintained and subjected to quality detection; the whole process is tracked and monitored from the first step to the seventh step, the dynamic state of the rectification pile foundation is known, and acceptance is organized. According to the technical scheme, the invention provides the construction method for the bridge cast-in-place pile in the soft soil area.
本发明涉及桥梁工程施工技术领域，其公开了一种软土地区桥梁灌注桩施工方法，解决了现有技术中的如何对倾斜造成的安全问题进行二次施工技术纠正的技术问题，包括：步骤一，开挖基坑：开挖基坑至倾斜桩基的桩底；步骤二，倾斜桩基桩位测量：确定其倾斜方向和角度；步骤三，深层取土卸压；步骤四，安装桩基纠偏模体；步骤五，灌注基坑，形成纠偏桩；步骤六，缝隙回填处理：经纠偏灌注后，倾斜的另一侧可能会出现缝隙，缝隙采用回填砂或土夹砂通过灌水后打夯密实；步骤七，纠偏桩养护和质量检测；步骤八，验收:从步骤一到七，全过程进行跟踪监测，了解纠偏桩基动态，组织验收。根据以上技术方案，本发明提供一种软土地区桥梁灌注桩施工方法。
