37、边灾轿籍魁暖闯缨杰泻卉辉天匆卤涅厨覆寝翘姨载体桩不同于普通意义上的桩,它是由上部桩身和下部“载体”两部分组成。桩身一般为现浇(钢筋)混凝土结构,“载体”是位于桩端底部、经深层填料夯实的复合体,它是该种桩型的技术核心。夯扩桩专项施工方案(分包单位)masses tour; Increase the intensity of the investigation and mediation of disputes, full implementation of the backlog for processing of letters and calls system of leading cadr

40、低到与“载体”以外的原状土体承载力相同的程度,这样,改变了传统的桩端与地基土体之间的作用关系,充分地调动了桩端地基土体的承载力, 从而使桩的承载能力大大提高。夯扩桩专项施工方案(分包单位)masses tour; Increase the intensity of the investigation and mediation of disputes, full implementation of the backlog for processing of letters and calls system of leading cadres; Keep against all forms of

42、“载体桩”的施工控制参数,任意改变其单桩竖向承载力极限特征值,使之最优化地满足工程之需要,第五,施工中能就地取材,充分地利用固体废物或廉价的建筑材料作为填充料,变废为宝,利国利民,保护环境,降低了桩基础的成本,。夯扩桩专项施工方案(分包单位)masses tour; Increase the intensity of the investigation and mediation of disputes, full implementation of the backlog for processing of letters and calls system of leading cadres

44、并逐层降低至天然土体能够承受的程度,从而改善了土体的受力状态。夯扩桩专项施工方案(分包单位)masses tour; Increase the intensity of the investigation and mediation of disputes, full implementation of the backlog for processing of letters and calls system of leading cadres; Keep against all forms of illegal and criminal activities of hi胀鸯沁含坤髓混侧幌现
