地下连续墙最大深度26米，宽度800mm，难度较大，希望对没有施工过连续墙的朋友们有所帮助。并且土开挖后还要再部施工衬，所以下一步还有一系列的问题和好的施工法，希望与朋友们共勉。
如果有想施工连续墙的朋友发给我，本人将全力支持各位朋友的需要。
本贴是按照施工顺序发的图片，希望大家喜欢，呵呵。

这就是地下连续墙施工的基本过程，当然看着简单，其中的步骤还是比较繁琐的，尤其是根据深度的不同，还有很多其他的技术难题。本工程地下连续墙目前已经完工，下一步还要土开挖和施作衬结构，相信网友们会有很大的兴趣，笔者将逐步上传照片和施工法，有兴趣的朋友可以关注。另外，如果有同类的工程需要，笔者将会全力帮忙，呵呵呵，希望你们看着高兴。
想问一下搂住，你们这种锁口管的效果怎样？混凝土绕到后面去得多吗？我们这里一般使用纯圆柱形的，经常绕管。
这种锁口管效果非常好，因为它不是纯圆形的，在与槽壁接触的地有两个突出的翼缘，，刚好与槽壁接触，相对密的多。当然，一点不绕浇也是不可能的。目前还没发现你说的那种情况。不妨试试。
开挖深度为26米。我们所用的泥浆为超泥浆，目前国最为先进的泥浆。国多采用膨润土（亦即皂土，Bentontie）泥浆，随着科技材料的发展，国外与、都已逐渐转换为高分子聚合物材料——聚丙烯醯胺（Polyacrylamide）超泥浆稳定液。这种液体是一种高浓缩性白色乳液，与水拌合后即产生膨胀作用，以提高水的粘滞度，在钻掘壁面形成一层富有韧性的胶质薄膜，防止钻掘平面之崩塌，达到稳定洞与沟槽之目的。这种超泥浆易于拌合，无粉尘污染，不需泥浆搅拌池、沉淀池，能促使悬浮泥沙产生凝絮，加速沉淀，并可多次循环使用。它突出的优点是无毒性、无污染，不影响环境生态。完工时的废液处理，仅需按水量1/750～1/500比例添加硫酸铝（明矾），充分搅拌后，水中酸碱值中和至6.0.～8.0之间，超泥浆之高分子链即断解、卷曲失效，稍置后即可排于下水道。
最近的连续墙部支撑刚刚做完，大家看看！
