- 摘要:
- 根据三江口地质、环境特点，决定盾构施工法为西气东输管道通过长江的推荐方案。盾构施工法具有工效高、安全性好、无公害等优点。文章介绍了泥水加压式盾构工艺及其出发井的选择、洞口止水措施、洞口外土体加固、盾构推进、同步注浆与补充注浆、管片预制与拼装等关键工序的施工技术。
The pipeline construction in west China gas transported to east China project needs pipeline crossing the Yangtze river at Sanjiangkou port. It is determined that the shield structure construction method will be a recommended program in west China gas transported to east China pipeline project according to the geology&environment in Sanjiangkou port area. Shield structure construction method has many advantages such as high working efficiency, good in safty & no一environmental pollution etc..The paper introduced the shield structure drilling method with mud & water pressure and the construction technique in some key process such as selection of starting well, measure of water一proofing in well head, earth consolidation in external well head, shield structure body propelling, synchronous pumping mud & supplement pumping mud, pipe piece premanufacturing & installation ete..2001,4(4): 4-7 收稿日期：2001-4-23分类号：TE973作者简介：1987年毕业于管道职工学院计算机专业，毕业后一直从事非开挖水平定向钻穿越施工，曾参加苏丹管线水平定向钻穿越尼罗河施工以及国内的黄河、黄浦江、松花江、辽河等大型河流水平定向钻穿越施工40余次，发表“水平定向钻技术用于长宁输气管道黄河穿越工程”、“水平定向钻在尼罗河穿越施工中的应用”等多篇论文。
