深基坑支护施工除了要求必须满足自身结构的安全、保证地下室施工安全顺利进行、确保周边环境与建筑物、道路管线的安全外,同时还必须实现施工对周边的环境影响最少,降低地下污染、降低造价的目的。而预应力锚杆技术,其不仅可决定支护结构的稳定性,而且还能有效控制基坑变形,在深基坑支护中起着相当重要的作用。预应力锚杆施工较复杂,施工技术要求高,施工过程中影响施工质量的因素较多,因此必须严格按规范要求进行施工,否则造成的后果非常严重,现通过具体工程实例进行禅述。
In addition to the requirements for the construction of deep foundation pit support, it is necessary to satisfy the safety of its own structure, to ensure the safe and smooth construction of the basement, and to ensure the safety of the surrounding environment and buildings and road pipelines. At the same time, it must also be implemented to minimize the impact on the surrounding environment and reduce the underground pollution. The purpose of reducing the cost. The prestressed anchor technology not only can determine the stability of the support structure, but also can effectively control the deformation of the foundation pit and plays an important role in the deep foundation pit support. The construction of prestressed anchors is complex, and the construction technology requirements are high. There are many factors that affect the construction quality during the construction process. Therefore, construction must be carried out strictly in accordance with the specifications. Otherwise, the consequences are very serious.
