摘要
目前,隧道降水施工工艺逐渐呈现多样化,选择科学合理的降水施工工艺是提升明挖隧道降水施工经济性和安全性的前提条件。管井降水方法以其独特的优势被广泛应用在隧道降水施工中。以京张铁路东花园隧道为例,结合现有技术以及经验,对明挖隧道中降水施工工艺进行了详细阐述,该工艺符合我国目前的明挖隧道工程事业发展标准和规范要求,能有效保证隧道降水施工的经济性和安全性,值得大范围推广应用。
The tunnel dewatering construction technology has been gradually diversified. Choosing scientific and reasonable dewatering construction technology is the prerequisite for improving the economy and safety of open-excavated dewatering construction. With its unique advantage,the method of pipe well dewatering is widely used in tunnel dewatering construction. Taking Dongyuan Tunnel of Beijing-Zhangzhou Railway as an example,the construction technology of dewatering in open-excavated tunnel is expounded in details. This technology can meet the requirements of the current development standards and codes of open-excavated tunnel engineering in China,which is worth popularizing and applying in a wide range.
