Construction method applied to unfavorable geology follow-up type pile casing bored pile
The invention discloses a construction method applied to an unfavorable geology follow-up type pile casing bored pile, and belongs to the technical field of drilling engineering.The construction method comprises the steps of construction preparation, pile position surveying and lofting, follow-up type pile casing burying, drilling in a follow-up type pile casing, hole cleaning, concrete pouring and follow-up type pile casing recycling. The drilling stability and integrity can be effectively improved, and the construction problem caused by complex geological conditions is reduced. The follow-up pile casing enhances the stability and the bearing capacity of the hole wall of the drill hole, so that the construction is safer and more reliable; meanwhile, after concrete is poured into the drilled hole, the follow-up type pile casing can be hoisted and recycled through hoisting equipment, the follow-up type pile casing can be reused, the construction cost is reduced, the technology is flexible and adjustable, adjustment can be conducted according to different geological conditions and project requirements, the actual construction requirement is met, and the construction efficiency is improved.
本发明公开了一种运用于不良地质跟进式护筒钻孔桩的施工方法，属于钻孔工程技术领域，施工方法包括施工准备、桩位测量放样、埋设跟进式护筒、在跟进式护筒内进行钻孔、清孔、灌注混凝土、回收跟进式护筒的步骤，采用多层跟进式施工，能够有效提高钻孔的稳定性和整体性，减少因地质条件复杂导致的施工问题。跟进式护筒增强了钻孔孔壁的稳定性和承载能力，使施工更加安全可靠；同时，在向钻孔灌注混凝土后，可以通过吊装设备吊起回收跟进式护筒，实现跟进式护筒的重复利用，降低施工成本，工艺灵活可调，可根据不同的地质条件和项目要求进行调整，以满足实际施工需求，提高了施工效率。
