摘要:
顶管技术具有施工方便、不中断地上交通、无噪声、无环境污染等优点，因此广泛应用于地下空间的开发利用，但在实际的顶管顶进施工中难免遭遇无法清除的障碍物，造成无法继续顶进的问题。依托武汉汤逊湖污水处理厂尾水排江顶管工程，提出一种施工方便、高效率的大直径顶管退管方法，阐述了退管工艺流程，并总结了施工过程中的关键技术，同时就二次顶进设计准备进行设定。实际工程效果表明，该退管方法适用于大直径顶管退管工程，能够很好地解决大直径顶管退管回退阻力大、反推力不足的问题，从而有效提高退管施工效率，降低施工成本。
Abstract:
Pipe jacking technology is widely used in the development of underground space due to its advantages of easy construction, no interruption of overground traffic, no noise and no environmental pollution, etc. However, in the actual pipe jacking construction, it is inevitable to encounter obstacles that cannot be removed, causing the problem of inability to continue jacking. This paper proposes a convenient and efficient method for withdrawing large diameter pipe jacking, based on the pipe jacking project of tailwater discharge river in Tangxun Lake WWTP in Wuhan, specifying the process of pipe withdrawing and summarizing the key technologies in the construction process, as well as setting the design preparation for secondary jacking. The actual engineering results show that the method is suitable for large diameter pipe jacking and can solve the problem of large diameter pipe jacking with high resistance and insufficient counter-thrust, thus effectively improving the efficiency of pipe jacking and reducing construction costs.
