近年来国家经济高速发展,农业机械化、产业化推进,农村大量的剩余劳动人口涌向城市,大中型城市住房供不应求。受城市土地面积的限制,商住房开始追求最小用地,最大建筑面积,高层建筑已经成为未来城市建筑的主流。在高层建筑工程施工中,地下室是不可或缺的基础工程,往往这些地下室的层高很大,就造成基坑必须挖深。深基坑的安全往往就是高层建筑基础施工中不可忽视的重要分部工程。本文笔者根据多年工作经验,对高层建筑深基坑土钉支护的环境造成的事故有很深刻的认识,仅以个人的经验浅谈深基坑土钉支护的环境事故成因及防治办法。
In recent years, the rapid economic development of the country, agricultural mechanization, industrialization, a large surplus of rural labor population flock to cities, large and medium-sized cities in short supply. Subject to the urban land area constraints, commercial housing began to pursue the smallest land, the largest building area, high-rise buildings have become the mainstream of future urban construction. In the construction of high-rise buildings, the basement is an indispensable foundation project, often large basement of these layers, resulting in foundation pit must dig deep. Deep foundation pit safety is often an important part of high-rise building construction can not be ignored. Based on many years of work experience, the author has a deep understanding of the accident caused by the environment of soil nailing support for deep foundation pit in high-rise buildings. The author only talks about the causes and prevention measures of environmental accidents caused by soil nailing in deep foundation pit based on personal experience.
