The Research on Construction Technology of Easily-Removable Combined Prestressed Special-Shaped Steel Plate Stiffening Core Cemented Soil Foundation Pit Support Based on Experimental Analysis

摘要

Apart from the multiple existing foundation pit support structures, this paper introduces the construction technology of an easily-removable combined prestressed special-shaped steel plate stiffening core cemented soil foundation pit support and studies and introduces its principles, technological characteristics, construction process and operating points. The technology organically combining the water stopping capability of the cemented soil and the high strength performance of the combined special-shaped steel plate has the characteristics of being highly permeability resistant, stiff and economical, is a green technology, and is applicable to the foundation pit support construction of various sorts of constructional engineering, highway engineering and embankment engineering.
