Construction method of large bridge deep pile foundation with high bearing capacity
The invention relates to the field of bridge pile foundation installation, and particularly discloses a large bridge deep pile foundation construction method with high bearing capacity, comprising the following steps: step 1, transporting a pile foundation to a detection area for bearing capacity detection; 2, the length, width and height of the pile foundation are measured and sent to a construction site for foundation construction; thirdly, foundation construction is conducted on the construction site according to the pile foundation data; fourthly, the pile foundation is installed in the foundation; fifthly, the pile foundation is maintained after being installed; slurry pumping secondary hole cleaning is adopted in pile foundation drilling, the hole cleaning quality is ensured, that is, drilling footage is stopped after hole finishing, a mudstone pump of a reverse circulation system of a drilling machine is used for continuously sucking slag, and clear water is put into a hole opening, so that the relative density of slurry is gradually reduced, the hole cleaning standard is met, and the slurry is circularly purified through a slurry purification device; water for hole cleaning is greatly reduced, water resources are saved, and the mud purification effect is good.
本发明涉及桥梁桩基安装领域，具体公开了一种承载力高的大型桥梁深桩基础施工方法，包括以下步骤：步骤一、将桩基运输至检测区域进行承载力检测；步骤二、测量桩基的长度、宽度和高度并发送至施工现场进行地基建设；步骤三、施工现场根据桩基数据进行地基建设；步骤四、将桩基安装在地基内；步骤五、桩基安装完成后进行维护；本发明在桩基钻孔采用抽浆二次清孔，确保清孔质量，即在终孔后停止进尺，利用钻机的反循环系统的泥石泵持续吸渣，并从孔口放入清水，使泥浆相对密度逐步降低，并达到清孔标准，且采用泥浆净化装置对泥浆进行循环净化，大大减少清孔用水，节约水资源，且泥浆净化效果好。
