摘要
以西气东输郑州黄河顶管工程4#沉井止水帷幕的设计与施工为例,详细说明了顶管沉井止水帷幕各设计参数确定以及施工方法的选择,并对顶管沉井止水帷幕所采用的高压旋喷技术做了较为详尽的介绍,该工程经验总结所得结论,对今后类似工程的设计与施工有一定的参考和借鉴意义。
With the design and construction of the No. 4 open caisson stag of transporting natural gas from the west to the east at Zhengzhou as an e various parameters for the open caisson stagnant water curtain in jacking ting natural gas from the west to the east, and the right choice of constr nant water curtain for the project xample, the determination of the tubes in the project of transporuction methods are dealt with in the paper, with the technique of high pressure jet grouting for open caisson stagnant water curtain introduced in detail. The conclusion of this project may serve as a useful reference for other similar projects in the future.
