深基坑支护不仅要求确保边坡的稳定,而且要满足变形控制要求,以确保基坑周围的建筑物、地下管线、道路等的安全,如今支护结构日臻完善,出现了许多新的支护结构形式与稳定边坡的方法,深基坑支护设计与施工是当前城市高层、超高层建筑突显的技术难题,复合土钉在深基坑支护,能减少边坡开挖、缩短施工工期、减少基础工程投资,并通过复合土钉支护来说明该技术在该工程中的应用,阐述其在该深基坑中应用的技术特点。
Deep foundation pit support requires not only to ensure the stability of the slope, but also to meet the requirements of deformation control to ensure the safety of buildings, underground pipelines and roads around the foundation pit. Nowadays, the support structure has been improved and many new branches have emerged The method of protecting the structure and stabilizing the slope, the design and construction of deep foundation pit support are the technical problems highlighted in the present urban high-rise and super high-rise buildings. The composite soil nailing is supported by the deep foundation pit, which can reduce the excavation of the slope and shorten the construction Duration, reduce the investment in basic engineering, and through the composite soil nailing to illustrate the application of the technology in the project, described its technical characteristics of the deep foundation pit.
