Design method for utilizing lower space of bridge crossing riverway to ensure integrity of park

Abstract

The invention discloses a design method for utilizing the lower space of a bridge crossing a riverway to ensure the integrity of a park. According to the level of a riverway navigation channel, designspecifications of the park and requirements for hydraulic engineering and the traffic function aspect of park roads of the park under the bridge, a landscape main bridge crossing a river is designedor a ramp way on the land within a certain range is designed into an approach bridge, and an important landscape node of the park is formed; clearance under the bridge is utilized to solve the integrity problem of the park on a planned land parcel on the junction between the river and a road network, and a large loop-line ground park road system of the whole land parcel and two small loop-line park road systems formed by means of treatment of bridge joints are formed in the park, or only the large loop-line ground park road system of the whole land parcel is formed in the park; meanwhile, separation of a road network traffic flow from a land parcel traffic flow under the bridge is achieved. By means of the method, the large loop-line ground park road system of the whole land parcel can beformed in the park, and the purpose of separating the road network traffic flow from the land parcel traffic flow under the bridge is achieved.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction such as municipal administration, gardens, water conservancy, and waterways, and specifically relates to an integrated design method for ensuring the space under bridges across rivers and parks. Background technique [0002] There are currently several methods for the overall design of parks in planning plots that ensure that rivers and road networks intersect: First, bridges crossing rivers in the road network are designed as flat bridges; The tunnel is then connected with the park’s ground or overhead garden road system to form a park road system, which realizes the overall design of the park in the planning plot where the river and the road network intersect. Bridges often cannot realize the navigation function of rivers. At the same time, the road network traffic flow across the river divides the land on both sides of the road network into two, and in fact, the integrated d...

[0002] There are currently several methods for the overall design of parks in planning plots that ensure that rivers and road networks intersect: First, bridges crossing rivers in the road network are designed as flat bridges; The tunnel is then connected with the park’s ground or overhead garden road system to form a park road system, which realizes the overall design of the park in the planning plot where the river and the road network intersect. Bridges often cannot realize the navigation function of rivers. At the same time, the road network traffic flow across the river divides the land on both sides of the road network into two, and in fact, the integrated design of the land cannot be truly realized.

[0003] The second is to use tunnels when the road network passes through the river. This method meets the requirements of the waterway and realizes the integration of the park plots. However, the project cost and post-operation and maintenance costs are much higher than those of bridges, which does not show any advantages.
