The purpose of the research and significance of Through the interchange bridge at home and abroad access to research, Huaihai Road and the Canal Bridge, according to the present layout, topography and road cross-situation, carry out a serious investigation, analysis, comparison, selection of appropriate interchange interchange bridge; carrying out of project feasibility demonstration, and to consider the vision of two decades the volume of traffic, after comparison, to determine the optimum type of bridge. Designed to be able to interchange bridge-type solution to the intersection of traffic jams, traffic delays and eliminating conflicts Department intersection points, thereby significantly improve the traffic speed and increase the traffic capacity, and ensure traffic safety, improve traffic environment, improve society economic benefits. Therefore, the bridge design and construction of Huaian city transport development is of great significance. generate the development of interchange Interchange of produce (1) the characteristics of cross-plane Planar cross-road are two or more roads intersect in the same plane or connections, and its characteristics are mainly embodied in the following areas: There is a danger point, the traffic complexity of public existence Noodles (2) ways to improve the cross-plane 1) From time to consider: the intersection of the various traffic flow line, from the time of separation, that is, through the police or control signal. 2) Implementation of Traffic Organization: Department set up at intersections all kinds of transport facilities or through the line, the installation of traffic signs and other traffic Drainage and Traffic Organization, so that traffic flow in the plane lines各行其道, the implementation of the separation. 3) construction of the interchange: By the construction of cross-line structure, so that intersection of the main line of traffic flow in space separated from the fundamental line of separation between the traffic flow at the same time interfere with each other through the construction of the ramp to the main line of traffic flow between the line connecting , realize the conversion between the flow of traffic. Interchange of produce The emergence and development of interchange has always been associated with motor vehicle traffic and the development of cities. With urbanization, development, delivery Just sub 20:22:13 Flux of the rapid development of car ownership is the rapid growth of the original traffic capacity of roads should not have been required to meet the growing traffic. At the same time, pedestrians, non-motorized vehicles and motor vehicle for Road between the phenomenon is becoming increasingly serious, the use of signal control and the plane deal with organizational measures such as traffic has been far from a fundamental solution to urban traffic problems exist. In this context interchange first came into being in the city, and quickly become the problems of urban traffic congestion problem of a medicine which is widely used. the development of interchange I With the emergence of high-grade highways, trunk roads of development, and improve the speed of vehicles, there is an urgent need to improve road capacity; At the same time, to ensure road safety is also of particular significance, all of which for the rapid development of the provision of interchange the premise. Highway Interchange in 1925, appeared in Germany. After this, interchange the fastest growing, most widely is the United States. Before and after World War II, Germany also built a substantial, high grade grade separation. In addition, as the economy and the rapid development of highway transport of substantial construction, the post-war Japan has also built a lot of functionality is better, economical and practical interchange interchange, and the diversification of forms of interchange design has provided a lot of experience, Interchange at design standards and design specifications can be made from results. Up to now, countries have built a lot of interchange, and gradually formed a style different characteristics. As China's urban road and highway construction and development, the construction of interchange ascendant. In urban and high-grade highways have been built a lot of interchange. According to incomplete statistics, China's Beijing alone, the Board go zones have been completed more than 100 Interchange, some interchange regardless of size, shape or design and construction standards, greening and beautifying the areas can be termedembodied in our country interchange of the ad hoc design and innovation.
