| 深厚卵石地区的基坑支护设计止水是关键,止水措施的成功与否,关系到整个项目的质量和安全。本文以深厚卵石层地区某基坑支护工程为例,采用复合土钉墙+三管旋喷桩的支护方式,介绍了三管旋喷桩止水帷幕的参数选取,以及其关键工序的控制措施,经现场验证该措施合理有效,其支护形式和止水措施可供类似工程参考。 |
| 英文摘要: |
| The design of foundation pit support in the deep pebble area is the key to stop water, the success of the stop water measure is related to the quality and safety of the whole project. This paper introduces the support case of a project in the area of deep pebble bed, the support method of composite soil nailing wall and three pipe jet grouting is adopted, introduces the parameter selection of three pipe jet grouting and the control measures of its key process,which is proved to be reasonable and effective on site, and its support form and water stop measures can be used as reference for similar projects. |
