Excavation design envelo
Abstract
This project is from Zhejiang Province by the Association for Development Group Co., Ltd.. Works by the office space and the corresponding component of the underground garage. By the Architectural Design Institute Co., Ltd. Design, Zhejiang Province. Cover: envelope system options, envelope system, the specific practices of the construction requirements of excavation, foundation-site monitoring and emergency measures, building envelope design that the design of retaining structure, such as working drawings. Gongshu District project is located in Hangzhou, the road west of Whitehead, good Yin Road south of the south for the vacant two-story building (the framework of the structure, shallow foundation). 0.00 of the project vis-à-vis the Yellow Sea Elevation 5.7m, the project site of the Yellow Sea floor elevation on average 4.40m. The description of this part of the structural design of the project, using some hand-count some of the rationale for the use of software and Venus are calculated. This combined with the calculation in favor of more access to knowledge and learning. Deeper the depth of the excavation works were 5.75m, 5.95m, 7.75m, 8.15m. Excavation area to silty clay soil mainly in the pit at the end of silty clay and silt at the junction, inferior nature of the works. After comparison and analysis of pile retaining system used to support the program increases. The main support the use of bored piles in order to cement mixing pile retaining structures composed of water, at the same time to reduce the lateral displacement of the deformation, and enhance the stability of pit slopes, in the foundation set up with support. Widely used in the program, but also very successful.
Key words: foundation bored piles of cement mixing pile enclosure
