深基坑桩锚支护结构加固施工

Reinforcing Construction of Pile Anchor Supporting Structure in Deep Foundation Pit

传统的深基坑加固施工技术综合性低、遗留问题较多,越来越难以适应日趋深大复杂的深基坑施工,所以需要应用新的桩锚支护方式对深基坑进行加固施工。首先,对深基坑桩锚支护结构加固施工进行设计,设计支护桩以做好准备工作,然后进行预应力锚杆施工,进行锚索的张拉以及锁定的施工,最后,实现深基坑桩锚支护结构加固施工。通过应用实例进行分析,与传统的加固施工方法进行对比,最终可知,文章设计的桩锚支护方法综合性高、遗留问题较少,更适用于深基坑加固施工。

The traditional deep foundation pit reinforcement construction technology has low comprehensiveness and many remaining problems,and is more and more difficult to apply to the increasingly deep and complex deep foundation pit construction.Therefore,it is necessary to apply a new pile-anchor support method to carry out Reinforcement construction.First,the reinforcement construction of the deep foundation pit pile-anchor support structure is designed,and the support piles are designed to prepare for the preparatory work.Then,the prestressed bolt construction is carried out,and the anchor cable is tensioned and locked.Finally,the deep foundation is realized.Pit pile anchor support structure reinforcement construction.Through the analysis of application examples and the comparison with the traditional reinforcement construction methods,it is finally known that the pile-anchor support method designed in this paper has high comprehensiveness and fewer remaining problems,and is more suitable for the reinforcement construction of deep foundation pits.
