万家寨引黄工程一、二级地下泵站开挖施工

Excavation Construction Of Primary and Secondary Underground Pumping Stations of the YRDP

万家寨引黄工程一、二级泵站为地下式厂房 ,共有洞室 1 2 0多个 ,它们类型众多 ,规格不一 ,在布局上立体交叉 ,纵横交错 ,相当复杂。文中论述了泵站洞室开挖的施工组织设计、具体施工过程及方法。由于施工安排合理 ,建立健全了施工质量保证及安全生产体系并予以有效地执行 ,减少了施工中的相互干扰 ,加快了施工进度 ,按计划圆满地完成了洞室开挖施工任务 ,经检查验收 ,施工质量均达到合同规定的标准。

The primary and secondary pumping stations of the YRDP are underground houses,they contain over 120 caverns which are of numerous types,varying specifications,and of overhead crossing,criss cross,and complication in layout.The construction organization design,construction procedure and construction method for cavern excavation of the pumping stations are illustrated in this paper.As the construction schedule had been rationally arranged,and as the construction quality guarantee and safety production system had been set up,and further,which were improved and carried out effectively at the same time,the disturbance each other in construction was decreased,the construction progress was quickened,the construction task of cavern excavation was perfectly accomplished according to the plan.Consequently,the construction quality has reached the standard specified in the contract through checking before checking acceptance.
