In order to further promote the development of innovation of deep foundation pit engineering in wuhan, Dec. 21, in the afternoon, the wuhan geotechnical engineering branch of civil engineering and construction institute and Shanghai strong foundation engineering co., LTD., a quiet park in wuhan hubei GongJian projects department jointly hold the seminar of experts, the fabricated all recycled steel composite support design, construction technology and application technology to carry out exchanges and explore.
In order to further promote the innovation and development of deep foundation pit engineering technology in Wuhan,12month21In the afternoon, the geotechnical engineering branch of Wuhan Civil and Architectural Society andShanghai Strong Foundation Engineering Co., LTDThe Hubei Engineering and Construction Project Department of Wuhan Qingjing Park jointly held an expert seminar. Yes Assembled fully recycled steel composite supportDesign, construction technology and application technology exchange and discussion.
As ONE OF THE ORGANIZERS OF THE SEMINAR, Shanghai QIANGQIANG FOUNDATION ENGINEERING CO., LTD HAS MADE BREAKTHROUGHS IN MANY KEY TECHNOLOGIES IN THE FIELDS OF SEA AND LAND FOUNDATION TREATMENT, FOUNDATION PIT ENGINEERING, PILE FOUNDATION ENGINEERING AND SLOPE TREATMENT, AND HAS BECOME a WELL-KNOWN ENTERPRISE IN FOUNDATION ENGINEERING design, construction AND TECHNICAL CONSULTATION.
In the seminar, Professor Liu Quanlin introduced the research results and application experience of the technology design and construction method of prestressed prefabricated fish belly beam steel bracing, and shared the application results of prestressed fish belly steel bracing system in deep foundation pits across the country.
The prestressed fish-belly steel support system is composed of a series of standardized steel components and assembled with bolts. By applying prestress, the inner support system can control the deformation of the foundation pit and protect the safety of the surrounding environment. It is a fully recovered and reused prefabricated support structure. The technology has the advantages of short construction period, large construction space, high safety, low cost, green construction, energy conservation and environmental protection.
As the first use of this technology in Wuhan, Wuhan Tranquil Park project, the foundation pit surface area1Over 10,000 square meters, most of the excavation to the end and the construction of the bottom plate. The maximum horizontal deformation of the foundation pit is controlled in20mmWithin, effectively protect the safety of the road and pipeline buildings around the foundation pit. The advantages of the technology are verified in basement construction period, construction cost and excavation speed.
Through on-site observation, technical discussion and communication, the experts attending the meeting fully affirmed the successful application of this technology in Wuhan, and supported its promotion and application in foundation pit projects around Wuhan.
