摘要
河北省保定市曲阳县南水北调中线京石段S18标漠道沟倒虹吸土方开挖施工共布置3条施工道路,下基坑道路、混凝土罐车运行道路、1号弃料场施工道路,为混凝土施工机械布料机安装运行及土方的顺利开挖而进行调整。通过计算挖掘机、15t自卸车、相应人员等资源配置做到合理搭配,基坑降水处理采用深井井点法进行。施工结果证明了该开挖施工方案既确保了工程质量、提前了施工工期、同时也带来了较大的经济效益。
Earth excavation is a common method of construction, and it is a mechanize construction which includes bulldozer, excavator and loader. Beside the progress, quantity and quality of the equipment, the statement, method and order of excavation will also directly affect the result of the excavation, so it is especially important to select a good, complete, perfect and reasonable method. Take an example of the earth excavation construction method from Mo Dao Gou inverted siphons of JingShi section S18 of south-to-north water diversion midline which is in QuYang district BeoDing city HeBei Province, which proves that a good method of excavation can not only ensure the quality of project and advance the construction schedule, but also can bring great economic benefit and obtain multiple profits.
