随着国家城市化建设的迅速发展,建筑物基坑施工越来越复杂,有些基坑没有放坡空间,采取单一的支护形式难以满足要求,需采取相应的多种组合支护措施进行施工,以满足工程安全性、实用性和经济性要求。现以某河流漫滩上的泵站基坑为例,针对现场实际情况,在基坑的不同位置分段采取了不同的支护工艺,使工程安全按期完成。经过实际监测,各观测点的位移、沉降均在允许范围内,证明支护体系是安全、成功的。
With the rapid development of national urbanization, the construction of the foundation pit is more and more complex, some of the foundation pit does not have the space for grading, and it is difficult to meet the requirements with a single form of support. Various combinations of support measures should be taken for construction , To meet the engineering safety, practicality and economic requirements. Taking a pumping station foundation pit on a floodplain as an example, according to the actual situation in the site, different supporting techniques are adopted in different positions of the foundation pit to make the project safety completed on schedule. After actual monitoring, the displacement and settlement of all observation points are within the allowable range, which proves that the support system is safe and successful.
