即墨市墨水河龙泉河综合治理工程截污干管施工设计
|
摘要
纵观国内外河道治理案例,让河道内的水变清是河道治理成败的关键,所以河道治理前先进行截污显得尤为重要。在即墨市墨水河龙泉河综合治理工程截污干管设计中,由于传统的施工技术难以满足工程需要,设计过程中根据不同地段的地质情况和环境因素,采用放坡开挖、基坑支护、顶管施工等3种施工措施。详细介绍了基坑支护和顶管施工两种工艺的设计技术要点,可为类似工程实施提供参考。
By survey of the domestic and foreign river administration cases,the key to ensure river management is concluded as to clean water in the river. So it is very important to construct the main sewer along the river before it is comprehensive treated. Among the design of main sewer pipe in Moshui River and Longquan River comprehensive project,the traditional construction technology is difficult to meet the needs of the project. So 3 kinds of construction measures were adopted including the slope excavation,foundation pit supporting and the pipe jacking construction according to the geological conditions of different locations and environmental factors. The key points of the design of foundation pit support and pipe jacking construction were introduced in detail,which could provide a reference for similar projects.
