灰浆灌注的现场浇筑混凝土桩与现场浇筑混凝土支撑墙是欧洲新兴的两门新技术,美国在其工程技术公司的主持下进行初次使用。其中现场浇筑混凝土桩技术鲜为人知,这里特加介绍。这种现场灌注桩,1979年由西德研制成功,通过向桩的顶端与四周高压浇注灰浆(即水泥砂浆)从而提高现场灌注桩的支撑力。美国工程技术公司在1983 1984年间建造开罗的美国大使馆工程中首次采用。该建筑由十五层高层部与二层低层部组成,地基为中密性砂石,原设计中预定采用分段状锥
In-situ cast-in-place concrete piles and cast-in-place concrete support walls made of mortar are two new technologies in Europe. The United States is using it for the first time under the auspices of its engineering and technology company. Among them, the technology of cast-in-place concrete piles is rarely known, and it is specially introduced here. This kind of on-site cast-in-place pile was successfully developed by West Germany in 1979, and the supporting force of the cast-in-situ pile was improved by high-pressure pouring mortar (ie, cement mortar) to the top and all around the pile. The American Engineering Technology Corporation was first used in the construction of the US Embassy in Cairo between 1983 and 1984. The building is composed of a fifteen-story high-rise building and a two-storey low-rise building. The foundation is a dense sandstone. The original design is scheduled to use a segmented cone.
