Recycled concrete mixing pile construction method
The invention discloses a recycled concrete mixing pile construction method. The recycled concrete mixing pile construction method comprises the following steps that a mixing pile construction site is leveled in advance, and all obstacles, including large stones, tree roots, household garbage and the like, on the ground and under the pile position are removed; according to the recycled concrete mixing pile construction method, a mixing pile and a precast pile are solidified to serve as a composite foundation pile, the bearing capacity of the pile body can be improved, a core pile of the cement mixing pile and peripheral cement soil are formed at the same time and are formed through spraying at the same time in a non-solidified state, so that the concrete of the core pile and the peripheral cement soil are mutually mixed to form a mixed zone in the solidification process, the core pile can support the whole concrete mixing pile more powerfully, the bearing capacity of the concrete mixing pile can be improved, operation time and steps are reduced, manpower and electric power cost can be saved, and the construction period is shortened.
本发明公开了一种再生混凝土搅拌桩施工方法，所述再生混凝土搅拌桩施工包括以下步骤：搅拌桩施工场地应事先平整，清除桩位处地上、地下一切障碍，包括大块石、树根和生活垃圾等；该再生混凝土搅拌桩施工方法，采用搅拌桩与预制桩固结作为复合基桩的方法，可提高桩体承载力，水泥搅拌桩的芯桩和外围水泥土同时成型，因两者在未凝固状态下就同时喷射形成，因此在凝固的过程中芯桩的混凝土和外围水泥土相互混合形成混合带，使芯桩对整个混凝土搅拌桩的支承更加有力，有利于提成混凝土搅拌桩的承载力，而上述施工设备和方法能够同时将芯桩和外围水泥土同时成型，减少了作业时间和步骤，有利于节省人力和电力成本，并且缩短工期。
