Study On The Design Of The Gate In The Eastern Part Of Jiaozhou City

In order to solve floods in large range because of the Yunxi River flood intrusion into tributaries during flood season.Through the analysis of the engineering geology and hydrology, combined with flood control, environmental protection and economic benefits to design this flood control gate, to solve the problem of flood and waterlogging in the lower reaches of the Dagu River.Dagu River in the upper reaches of recent years after the treatment, basically reached the SO-year flood defense standards, has received tremendous economic and social benefits. However, the Dagu River downstream of the lack of flood control buildings, so frequent floods received, resulting in large-scale loss of personnel and materials.Jiaozhou City, east of the flood detention area is located in the Yunxi River and Dizi River and Dagu River estuary. And Yunxi River floodgate joint use of the flood storage and storage flood prevention to prevent flooding Dagu River water level is too high, resulting in a relatively complete flood control, moisture-proof engineering system. The total area of detention basin is about 16km2, and the total amount of flood detention is 27.54 million m3. After the implementation of the project can improve Jiaozhou City and the eastern industrial park flood control capacity to 50 years once the flood control standards, while the industrial water supply to the nearby, so as to solve the industrial water problems. In this paper,the main purpose is to design flood control gate, meanwhile puts forward some concrete methods of construction and management, Such as the use of the overall flat-bottomed gate program, gate pier at the use of cyclotron drilling bored pile foundation, the work of the gate with an arm tilting steel gate supporting integrated hoist to achieve rational layout of the project, the effect of small investment.hoping to provide some reference for the design and construction of flood control gates.
