11、钻孔灌注桩环保专项施工方案一、工程概况1、工程简介我公司承建的国道318 线林芝至拉萨公路改造工程林芝至工布江达段第四标段，位于林芝地区工布江达县境内，起止桩号K4296+00A K4324+40Q线路起 于巴河镇秀巴村，终于拿巴村，线路全长 28.4km。工程总造价为12.55亿元，合 同工期为2年。工程主要技术标准为：设计速度 80km/h;整体式路基宽21.5m； 双向四车道一级公路；地震基本烈度7 度；设计洪水频率特大桥1/300、其它桥涵和路基1/100。主要工程量有：路基土石方272.2 万立方米，防护砌体36.5万立方米, 桥梁 6163 米 /15 座，其中特大桥1117 米

12、/1 座，大桥4980 米 /13 座，中桥 66 米 /1 座，涵洞13 道，通道21 道，设互通式立交1 处。二、主要施工工序钻孔灌注桩施工的工序分为：平台施工、护筒的制作、埋设、泥浆制作、排放、 钢筋场地的布设及钢筋制作、钻孔、 声测管制作及安装、钢筋笼制作及安放、安装导管、灌注水下砼、测桩验收等10 个主要部分。在钻孔桩施工过程中，每台钻机一般配备6 人， 每 3 人为一班，每班的 3 人中有一人是钻机机长，负责在移钻机、钻机就位、钻机钻进过程中的所有事项。泥浆主要产生在钻桩的过程中，主要作用是对孔壁的静压力和泥浆在孔壁上形成的泥皮可以有效地防止孔壁坍塌。除此之外，具有一定粘度的泥浆

13、可以携同泥渣一起排出。为了使泥浆能够更好的起到护壁效果，一般在开 钻时的造浆过程中，投入一定量的膨润土，增加泥浆的粘度。膨润土有钠和钙质两种，钠质膨润土较钙质为优，钻孔泥浆中用量也很大。膨润土泥浆具有比重低、粘度好、含沙量少、失水量少、泥浆薄、 稳定性强、固壁能力高、钻具回转阻力小、钻进率高、造浆能力大等优点。膨润土作为泥浆原料的一般用量为水的8% ， 即 8kg 膨润土可掺100L 的水。三、环境敏感点ctivities,compre hensive andtamping SafetyFoundation .Troubleshooti ng,manageme ntmechanism,give

38、产污形式主要是挖机进行场地平整时的噪音污染和混凝土浇筑时的罐车扬尘引起的大气污染；产污的特点是时间短，相对集中；产污数量相对较少。3、泥浆池、沉淀池、循环池的挖设泥浆池、 沉淀池、 循环池的挖设的产污形式是破坏当地原有的生态环境；产污特点是持续时间长，产污点分散，具有一定的方位性；产污数量相对较多。4、泥浆的制作泥浆的制作过程产污的形式是水污染和土源污染；产污的特点是突发性强，在泥浆制作中，如果泥浆管连接不牢固或泥浆池四周的土堰未压实不牢，都可能产生泥浆外溢现象；产污的数量具有不确定性，主要根据造浆的数量而定。5、钻孔钻孔过程中的产污形式主要是水污染、土源污染、大气污染、噪音污染；产Deleg
