SMW Method Pile In Excavation Support Technology In Comprehensive Application Of SMW Method Pile In Excavation Support Technology In The GCL Commercial And Residential Projects

SMW method is relatively new technology and support construction of a foundation pit from abroad, China’s first in the early 1990 s by the introduction of technology and the global world in Shanghai commercial foundation pit was first successfully applied. Because of SMW process is simple, short construction period,low cost, save steel, underground space saving, safe and reliable, consistent with national saving-oriented society and the development of recycling economy requires,in the late 1990 s, the Ministry of Construction as a key promote the project. After that it has been widely promoted. This article is in this context, Pit Hill Road for a view of protecting commercial and residential projects applied research.Firstly, for the type of general excavation, the basic concepts, features,applications, and research status of theoretical knowledge were introduced, especially for the process principle SMW method pile construction process, construction elements were introduced.In this paper, commercial and residential projects View Hill Road excavation as a research object, first introduced the geology of the project, support form, supporting the practice, support control principles, construction and monitoring requirements.Then the characteristics of different types of retaining structure comparative analysis demonstrates the SMW Method piles supporting the economic program adopted by this project, advanced and reasonable. Finally, the project is designed for the excavation project management system to determine the appropriate project management organization to develop a major resource demand planning, project managementobjectives clearly, and construction overall plan.Finally, for the containment system and the support system of SMW Process Pile construction program carried out specific research, including the envelope surface treatment, foundation earth excavation operation, foundation drainage, excavation monitoring, processing and pit pit inside Finally, removal, etc. support the construction technology summary.To achieve excavation and construction quality management objectives, develop a project management system quality objectives, quality and safety and schedule assurance measures to ensure the quality of construction of the Project Management Foundation to achieve objectives. Finally, a third-party independent monitoring test nearly five months, verify the excavation deformation to meet the design requirements for the smooth progress of the subsequent main project provides the construction period, quality, safety and security.Thesis conclusions are conducive SMW Method pile in excavation support projects to help achieve the project objectives, but also provide experience for future projects.Thesis conclusions are conducive SMW Method pile in excavation support projects to help achieve the project objectives, but also provide experience for future projects.
