针对机场线华泾站地下连续墙接头形式的变更研究
|
Abstract:
文章以上海市域线机场联络线(西段) JCXSG-4工程为例,对原有65 m地下连续墙套铣接头进行变更研究,采用类似法的理论研究方法,对各个接头进行对比,最终变更为H型钢接头,并且通过实际施工的防渗漏效果、功效及成本分析,验证了H型钢接头更加适用于此深度的地下连续墙,期望给相似项目提供经验。
Taking the JCXSG-4 project of Shanghai Regional Line Airport Liaison Line (West Section) as an example, this paper studies the change of the original 65-m underground diaphragm wall sleeve milling joint, adopts the theoretical research method of similar method, compares each joint, and finally changes it to H-shaped steel joint, and through the analysis of the anti-leakage effect, efficacy and cost of actual construction, it is verified that the H-shaped steel joint is more suitable for the underground diaphragm wall at this depth, and it is expected to provide experience for similar projects.
