Secondary stirring construction method for micro-vibration immersed tube stiff composite pile
The invention relates to a secondary stirring construction method for a micro-vibration immersed tube stiff composite pile, and relates to the technical field of composite pile stirring construction. The stiff composite pile comprises a cement stirring pile outer core and a concrete pile core; the method sequentially comprises the following steps that construction preparation and secondary mechanical stirring and material collecting device machining and manufacturing are conducted at the same time in two aspects, on one hand, the two steps of cement stirring pile construction and micro-motion pipe sinking are conducted in sequence, and on the other hand, the two steps of secondary mechanical stirring and material collecting device installation and commercial concrete secondary stirring are conducted in sequence. A pile core pouring step is carried out after the micro-motion pipe sinking step is finished, and a vibration pipe drawing step is carried out after the pile core pouring step is finished; the secondary mechanical stirring and collecting device is used in a construction site, commercial concrete is directly purchased in the pouring period, and then the pile core can be poured by improving the workability in the site, so that the construction cost is reduced, meanwhile, the transition transportation time of the commercial concrete is shortened, and the concrete construction efficiency is improved.
本申请涉及一种微振动沉管劲性复合桩二次搅拌施工方法，涉及复合桩搅拌施工的技术领域，所述劲性复合桩包括水泥搅拌桩外芯和混凝土桩芯；其依次包括如下步骤：施工准备和二次机械搅拌集料装置加工制造，然后分为两方面同时进行，一方面依次进行水泥搅拌桩施工和微动沉管两个步骤，另一方面依次进行二次机械搅拌集料装置安装以及商品砼二次搅拌两个步骤，微动沉管步骤结束后进行桩芯浇筑步骤，桩芯浇筑步骤完毕后进行振动拔管步骤；本申请在施工现场使用二次机械搅拌集料装置，浇筑期间直接购买商品混凝土然后到现场改善一下和易性就可以浇筑桩芯，既降低了施工的成本，同时也节省了商品砼转场运输时间等，提高了混凝土施工效率。
