水泥搅拌桩试验桩施工方案Pile Test Construction Plan of Cement MixingPile一、原理 I. Principle and Theory水泥搅拌桩是利用水泥作为固化剂的主剂，通过搅拌桩机将水泥喷入土体并充分搅拌，水泥与土发生一系列物理化学反应，使软土硬结而提高路基强度。水泥搅拌桩是软基处理常见的有效方法.Cement mixing pile, an effective way to soft treatment, whichadopts cement as the main host of curing agent， insert cement intosoil body through mixing pile machine， to improve the strength andintension of sub grade in the source of soft soil hardening by aserious physical and chemical reaction.二、试验段里程 Sections of test确 定 试 验 段 里 程 为 DK12+773 DK12+833 。 It was confirmed that thetest section from DK12+773-DK12+833。三、工程概况 The brief condition of projectDK12+673DK12+833 段软土路基分布在丘间谷地中，该段地形平坦，表层主要为流塑-软塑状黏土，灰色、灰黑色，含有机质，土质不均，含少量细砂颗粒;下伏可塑-硬塑状砂黏土。采纳水泥土搅拌桩复合地基加固，桩径 0.5m。DK12+673-DK12+833 located in valley between hills, soft subgrade, with plat and smooth land form， the top soil is gray andgray-black fluid plastic clay, containing organic materials and fewfine sand dust, underlying waxy and hard plastic sand clay.Adopting cement mixing pile to harden foundation, dimension of pileis 0.5m.四、设计参数 Designation parameter。1、试验桩位置：DK12+803DK12+833。Location of test pile: DK12+803—DK12+833.2、桩长:根据设计图纸确定为 5m。Length of pile： 5m as indicated in drawing.3、桩径：① 5 mm;桩底穿透软土至硬底层不小于 1.0m。Dimension of pile： ① 5 mm; pile bottom through soft soil tohard bottom as least 1。 0m.4 、 水 泥 掺 入 量 : 按 室 内 配 合 比 进 行 试 桩 ， 水 泥 用 量 在35kg/m、40kg/m、45kg/m、50kg/m、55kg/m 中进行比选，进行室内配合比试验，每种配合比现场施工试桩 2 根。Insert quantity of cement: accordin...
