Large-diameter super-long cast-in-place pile construction method
The invention relates to the technical field of cast-in-place pile construction, in particular to a large-diameter super-long cast-in-place pile construction method. The large-diameter super-long cast-in-place pile construction method specifically comprises the following steps of construction site leveling, pile position positioning, pile casing embedding, hole drilling, hole cleaning, reinforcement cage hoisting, guiding pipe installing, sediment thickness checking, secondary hole cleaning, concrete pouring and pile casing pulling out. In the drilling process of a cast-in-place pile, the length of an embedded pile casing is increased according to the situation that whether a cast-in-place pile hole collapses or mucky soil exists or not, so that forming of the cast-in-place pile hole is guaranteed; the problem that hole collapse is prone to occurring in the cast-in-place bored pile construction process in the prior art is solved.
本发明涉及灌注桩施工技术领域，具体涉及一种大直径超长灌注桩施工方法，具体包括以下步骤：施工场地平整、桩位定位、埋设护筒、钻孔、清孔、吊装钢筋笼、安装导管、检查沉碴厚度、二次清孔、灌注混凝土以及护筒拔出。在灌注桩钻孔过程中根据灌注桩孔是否塌孔或者存在淤泥质土的情况，增加埋设的护筒的长度，以确保灌注桩孔的成型。解决了现有技术中的钻孔灌注桩施工过程中易出现塌孔的问题。
