摘要
根据株柏煤矿第四系地层工程实际、水文地质特征和安全高效需求,在原有沉井工艺的基础上,进行升级优化,并在新立井沉井段实现了安全、高效、快速、理想的效果。采用组合式箱式沉井模板不拆模、导向装置系统和预留注浆管注浆技术,加大了施工进度,具有一定的应用和推广价值。
According to Zhubai Coal Mine＇ s actual engineering of quaternary strata and hydrogeological characteristics of safe and high effective demand to upgrade and optimize the original caisson technology. And the new shaft section of open caisson has realized safe and efficient, fast, and the ideal effect. Using combined box template not ripping open caisson, guide system and reserved grouting pipe grouting technology, increasing the construction progress, has a certain application and popularization value.
