摘要
结合包头新都市区综合管廊项目工程实例,根据当地砾砂层地质条件及管廊施工不得影响交通的要求,在矩形管廊施工中采用预制顶推施工技术。介绍了该技术的控制要点。工程实践结果表明,矩形管廊暗挖顶推施工技术切实可行,对上部交通基本无影响,大幅度缩短工期,安全性高,具有良好的社会效益和经济效益。
Based on the composite pipe gallery engineering practice in Baotou,according to the gravel geology conditions and traffic requirements,precast jacking construction technology was adopted in rectangular pipe gallery,and its control points in construction was introduced. The practice shows that this method has no influence on traffic,reduces the period,ensures the safety,has good social efficiency and economic benefits.
