City Overview

Jinhua, ancient Wuzhou, located in the middle of Zhejiang Province, is an central city of the Yangtze River Delta, and a national historical and cultural city.

Jinhua is the geographical center of Zhejiang, with the ecological resources of the north and south mountainous, across east to west connecting Jinqu Basin of Zhejiang-Jiangxi east-west ecological corridor. it is an important channel from Zhejiang-Jiangxi inland to the sea, connecting Hangshao Plain and Poyang Lake plain. The space of riverside plain and platform accounts for about 57%, and the hills and low mountains account for about 43%.

The water system of Jinhua belongs to the Qiantang River system, and the topography of the corridor basin gives birth to the water system pattern of “three main rivers and hundreds of streams from north to south”.Dongyang River flows from east to west through Dongyang, Yiwu, Jindong District, and joins Wuyi River at Yanwei Island to form Jinhua River, forming the skeleton of “three rivers”. Dongyang River, Wuyi River and Jinhua River constitute the main east-west water corridor of Jinhua city.

Since the establishment of Wushang County in the Qin Dynasty, the central urban area of Jinhua has experienced five main stages of evolution. Before the founding of the People’s Republic of China, it mainly developed in the north of the river, and the scope of Yingcheng was basically within the scope of Luocheng. After the founding of the People’s Republic of China,  city space gradually expanded to the west, south and east, forming a new overall development pattern.

The total urban area of Jinhua is 2,049 square kilometers, with the population of 1.489 million(2022).The population of Zhejiang Province has an obvious tendency to centralize to the central city of the metropolitan area. The population of Jinhua has rapidly gathered, and the growth rate has jumped to the third place in the province. The pressure bearing capacity of the relevant urban infrastructure has encountered challenges.

Project overview

Jinhua is located in the geographical center of Zhejiang, and is the throat of the inland to coastal mountainous corridor between Zhejiang and Jiangxi provinces. The regional ecological pattern has created an overall pattern of “two mountains and one river” in Jinhua urban area, with mountains extending from east to west beside the river, forming a picturesque river valley spanning a hundred miles.

The Dongyang River converges from east to west, and the Wuyi River converges from south to north to the Jinhua River. 16 bridges of various types, including municipal bridges, pedestrian landscape bridges, railway bridges, etc., have been built within the scope of the Second Ring Road in Jinhua River, Dongyang River, and Wuyi River, forming the interconnection of the three rivers and six banks.

At present, with the expansion of the urban core area to the Qianxi section, it is imperative to connect the main road Jinxing Street from north to south. In order to further improve the urban transportation network, alleviate the traffic pressure across the river in the western part of the city, and drive the renewal and development of the Qianxi section and Qiubin Industrial Zone, a new Jinxing Street Bridge is planned.

The Jinxing Street Bridge roughly runs in a north-south direction. After crossing Jinhua River and Shuangxi West Road on the south bank of the bridge, it connects with Jinxing North Street and lands. After crossing the planned Wujiang West Road on the north bank, it connects with Gongmao Street and lands. The Jinxing Street Bridge, as a key link in the connection of Jinxing Street and a landmark project in the western part of the main city, should be designed and constructed with high quality. Based on this, the international solicitation of Jinxing Street Bridge plans has been initiated.

Solicitation Content

 

Scheme design content

Bridge traffic and connection scheme on both sides

The bridge design needs to reasonably solve the cross-river motor vehicle, pedestrian and non-motor vehicle traffic, as well as the traffic planning and connection study for the connection between the express and slow system of the Jinxing Street Bridge and the Binjiang Road (Shuangxi West Road, Wujiang West Road and walkway). The road profile design should meet the requirements of motor vehicles and non-motorized lanes riding over the bridge.

The approach section of the bridge intersects with a number of east-west roads on both sides of the north and south, and the traffic at the beginning and end of the bridge as well as the side roads should be reasonably designed to improve the north-south traffic efficiency and reduce the impact on east-west traffic.

 

Shape design of bridge

Through various design techniques, the form of the bridge presents an organic whole, a harmonious rhythm and a full performance of tension.

The shape design of bridge should be both symbolic and harmonious. The shape should be coordinated and unified with the surrounding city skyline and style, and complement with the landscape and urban style on both sides of the Jinhua River, so as to shape the beauty of the landscape bridge spatial structure.At the same time, we should deal with the creation of node image and emphasize the identification of landmarks.

 

Landscape scheme design on both sides and under the bridge

The landscape scheme of the surrounding area of the connection is carried out, and the possibility of comprehensive utilization of the space under the bridge is explored to improve the utilization rate of the bridge space.The specific design range is determined according to the wiring scheme.

 

Bridge flood lighting design

Make full use of the optical properties of various lamps to create a dazzling but not dazzling, simple but not simple, gorgeous and solemn modern landmark bridge night scene.The design should be integrated into the design concept of the bridge scheme, and fully show the basic idea that night lighting is an important supplement to the urban landscape. Through the change of light intensity and color combination, the bridge can vividly show its unique style after the fall of the night.

 

Consider the reservation of relevant municipal pipelines, including rain drainage pipes, traffic safety facilities, road and bridge lighting, monitoring, road greening and ancillary facilities within the scope of the project.

Design principles

 

Reasonable structure, safety and durability:

The selection of bridge type should comprehensively consider location selection, river width, channel requirements, structural form and technical feasibility to ensure the stability and rationality of the structure.

 

Based on the network, function priority:

By fully studying the position and role of the project in the urban road network, the traffic system of the northern and southern sections of the Jinhua River is improved, and the traffic service capacity is ensured to connect smoothly with the traffic planning, and the comprehensive carrying capacity of the roads in the area is improved.

 

Modeling coordination, highlighting characteristics:

The shape of the bridge needs to be coordinated and unified with the surrounding city skyline and style, and complement the landscape and urban style on both sides of the Jinhua River, so as to shape the beauty of the spatial structure of the landscape bridge.Pay attention to the characteristics, can show Jinhua culture and landscape characteristics, reflect the location characteristics of bridge construction and urban cultural heritage.

The overall layout and structure selection of the bridge should deal with the creation of the node image and emphasize the identification of the landmark.The plan needs to be in line with the grade of the road, and the purpose is to create an original and iconic urban architecture.Combined with the skyline control requirements of the overall urban design, the land plot faces the ridge of the city developing along the river across the river, and forms a landmark effect through the shape or height of the bridge, with the overall height controlled within 100 meters.At the same time, through the comparison of multiple physical schemes, the interactive relationship between the urban mountain viewing corridor and the surrounding landmark buildings is handled well, and the optimal scheme is selected.The bridge body should be differentiated from the existing bridges on the Jinhua River, Dongyang River, and Wuyi River within the scope of the Second Ring Road.

The specific height and structure of the bridge need to be verified in the 3D model with the surrounding land, especially for the core area of the Three Rivers and Six Banks, and the perspective of the West Island Head of Wubaitan.

 

Economical and cost controllable

The construction cost of main bridge and approach bridge should be reasonably controlled to achieve a good balance with bridge type and effect.
