摘要
介绍了在排桩支护结构中,开挖前通过微型钢管桩注入水泥水玻璃混合液,胶结固化桩间土,以解决桩间流泥、流砂及坍塌问题的工程实例。这种事前支护法对相似工程具有一定的参考价值。
An engineering case related to prmgrouting is introduced. In this case, before the excavation of row-pile support, the intermixture of cement-sodium silicate is injected into the micro steel tube pile, in which soil between piles is cementation and solidification in order to deal with such problems as drift earth, drift sands and callapse. Hence the pre-support can provide reference for similar projects.
