泵站深基坑“放坡+钢板桩支护”施工研究

Research on the Construction of"Sloping+Steel Sheet Pile Support"for Deep Excavation of Pump Stations

泵站深基坑“放坡+钢板桩支护”施工是一种常见的基坑支护方法,它结合了放坡和钢板桩支护的优点,能有效地提高基坑的稳定性和安全性。文章结合河南省商丘市省道209线(豫鲁交界—国道310)公路改建工程,主要介绍了泵站深基坑“放坡+钢板桩支护”施工的工艺流程及安全与环保措施,以期为相关工程提供参考和借鉴。

The construction of pump station deep foundation pit using sloping&steel sheet pile support is a common method of foundation pit support,which combines the advantages of sloping and steel sheet pile support,and can effectively improve the stability and safety of the foundation pit.Based on the reconstruction project of Provincial Road 209 in Shangqiu City,Henan Province(from the junction of Henan and Shandong to National Road 310),this paper explores the construction process and safety and environmental protection measures of sloping&steel sheet pile support for deep foundation pits of pumping stations,hoping to provide reference and guidance for related projects.
