Construction method of bridge pile foundation
The invention relates to the technical field of bridge pile foundations, and discloses a construction method of a bridge pile foundation. According to the method, a construction site is detected through a detection tool, the geological condition is determined, and a locking opening is formed in the periphery of a pit opening obtained after preliminary excavation is performed on the position of a pile foundation; and a corresponding excavation mode is selected according to the geological condition of the pile hole construction area to continuously excavate the pile hole below the locking opening, a concrete protection wall is poured while excavating until the required pile hole is obtained, and then a pile foundation is poured, so as to obtain the bridge pile foundation. By arranging the locking opening at the pithead position of the pile hole to reinforce the construction site of the pile hole, the probability that an inclined hole is prone to occurring during drilling is reduced, thebearing capacity of a built pile foundation is improved, falling of construction residues is reduced, and besides, corresponding excavation modes are selected according to different rock stratums during pile hole tunneling; and the problem that the construction difficulty is large when complex geological conditions such as many rock stratums occur during bridge pile foundation construction is solved, and the construction quality of the pile holes is guaranteed.
本发明涉及桥梁桩基技术领域，公开了一种桥梁桩基的施工方法，该方法通过探测工具对施工场地进行探测并确定地质情况，在桩基位置进行初步挖掘后得到的坑口周围设置锁口，根据桩孔施工区域的地质状况选择对应的挖掘方式对锁口下方继续进行桩孔的挖掘，挖掘的同时浇筑砼护壁，直到获得所需的桩孔后进行桩基的浇筑，从而得到所述的桥梁桩基。通过在桩孔的坑口位置上设置锁口加固桩孔的施工场地，降低钻孔易出现斜孔的概率，提高了建造出的桩基承载力，以及减少施工残渣的掉落，同时还根据桩孔掘进时根据不同岩层选择对应的挖掘方式，解决了在桥梁桩基施工时遇到如岩层较多等复杂的地质情况时施工难度较大的问题，保证的桩孔的施工质量。
