自锁抗浮锚杆在某地下室工程中的应用

The application of self locking anti floating anchor in a basement project

与常用的抗浮桩相比,抗浮锚杆对底板的作用更接近于均匀布置,更有利于底板的防裂抗渗,且布置灵活、施工简便、效率高、绿色环保,且节约了材料、人工、机械等资费,使建筑工程降本增效。自锁抗浮锚杆利用根部扩大头机械咬合力来锚固,无需较长的锚固长度就能生成较大的锚固力,减少工程量,与常规锚杆相比锚固更可靠、造价更低。自锁抗浮锚杆属新技术,对施工有更高要求,唯有采用合理的施工工艺、施工技术措施,对施工中的要点进行合理的掌控,才能有效地提升自锁抗浮锚杆施工的整体质量和耐久性,保障地下室使用安全与稳定。文章重点介绍了自锁抗浮锚杆的施工工艺、质量保证措施和锚杆的防腐措施。

Compared with the commonly used anti floating pile,the role of anti floating anchor on the floor closer to uniform layout,more conducive to the bottom of the crack and anti permeability,flexible layout,convenient construction,high efficiency,environmental protection,and saves materials,labor,machinery and other charges,make the construction project cost reduction.Anti floating anchor with self-locking enlarged root mechanical bite force to anchorage,no longer need to generate the anchorage length of anchoring force is larger,reduce the amount of construction,compared with the conventional anchor more reliable,lower cost.Anti floating anchor lock belongs to a new technology,there are higher requirements on the construction,only adopted the technology of construction process,reasonable,the key points of the construction of the reasonable control,the overall quality and durability can effectively enhance the self-locking anti floating anchor construction,guarantee the safety and stability of the basement.The paper focuses on the construction technology,quality assurance measures of self locking anti floating bolt and the anticorrosion measures of anchor bolt.
