Reclamation From The Sea Of Land In Tianjin Harbor Industrial Zone

With the deepening of economic construction of the Binhai New Area, the land resources is increasingly becoming a major bottleneck that restricts its development. Tension, increased land acquisition costs of land resources, to solve this problem of Reclamation land construction is undoubtedly an effective means of use of the new district coastal beach.Harbor Industrial Zone as one of the nine functional areas of the Binhai New Area, is the reclamation from the sea made land formation offshore industrial zone, positioning heavy equipment manufacturing as the leading ecological economic zone for the construction of the northern China, Tianjin and heavy equipment, heavy and chemicalthe aggregation determines the engineering of a high standard of Reclamation land.Land in Sea is a systematic project involving many technical applications, there are higher requirements on construction equipment, construction technology, engineering materials. After years of accumulation and development of the Harbor Industrial Zone is also basically formed a Land in Sea engineering technology with its own characteristics, adapted to the need for rapid development of economic construction. Shi process reclamation from the sea made land is divided into three parts:the cofferdam forming technology, land formation technology, soft-based processing technology.In this paper, a detailed description of the three parts, focusing on the land formation of the foundation approach. Special geological conditions of the Harbor Industrial Zone, the second straight row of vacuum pre-pressure technology to deal with ultra-soft soil with an engineering example, and analyze the degree of consolidation and bearing capacity of foundation soil after the reinforcement of the technology with the conventional vacuum pre-pressure reinforced changed. Provide the basis of the promotion of the technology.
