Construction method for pile splicing of rotary excavating cast-in-situ bored piles
The invention relates to a construction method for splicing a rotary excavating cast-in-situ bored pile, which is suitable for a house building with a piled raft foundation, and is characterized by comprising the following steps of: a, processing the end of a concrete broken pile, b, splicing a broken pile reinforcement cage, c, processing base concrete, and d, erecting a template at the position of the spliced broken pile reinforcement cage. And e, pouring concrete. Compared with a traditional method, the construction method for splicing the rotary excavating cast-in-situ bored pile has the advantages that the square wood formwork is adopted to replace a sinking steel casing, plasticity is high, the forming specific gravity is large, bearing capacity is high, construction is convenient, the overall stability of the spliced pile can be improved, the problems that quality defects caused by pile breaking do not affect foundation safety and the like are solved, the work efficiency can be improved, and the construction cost is reduced. The method has the advantages of being simple in structure, convenient to construct, capable of avoiding cost waste caused by additional pile adding and re-drilling pouring, remarkable in economic effect and good in applicability and application effect.
一种旋挖钻孔灌注桩接桩的施工方法，适用于桩筏基础的房屋建筑，其特征在于包括以下步骤：a、混凝土断桩端头处理，b、接长断桩钢筋笼，c、基底混凝土处理，d、搭设接长断桩钢筋笼部位模板。e、浇筑混凝土。本发明的旋挖钻孔灌注桩接桩的施工方法与传统做法相比，采用方形木模板代替下沉钢护筒，可塑性强，成型比重大、承载力高，施工方便，不仅能够提高接桩整体的稳定性，解决断桩造成的质量缺陷不影响基础安全等问题，而且还能提高工效，方便施工，避免了额外加桩和重新钻孔灌注的成本浪费，经济效果显著，具有良好的适用性和适用效果的优点。
