brief introduction
Haiyang-Jimo sea-crossing bridge project was approved by Shandong Development and Reform Commission, planned and designed by Shandong Transportation Planning and Design Institute, and built by Shandong Luqiao Group.
There are 164 street lamps on the bridge, which will all be turned on at night. After opening to traffic, the speed limit of passing vehicles is 80 kilometers per hour. The cross-sea bridge is free of charge, and passing vehicles are free of bridge tolls.
geographical position
The sea-crossing bridge is located at the T-shaped estuary where the Yellow Sea meets T-shaped Bay. From Jiangjiazhuang Village, Xin 'an Town, Haiyang, to the south via1.38km, from Yadao via1.92km to the shack wharf in Fengcheng Town, Jimo. ..
Engineering construction
The planning of the cross-sea bridge began in 2007, was approved in 2008, and construction started in March 2009. It lasted for three years and the total investment reached 500 million yuan.
work progress
On March 2, 2009, a grand groundbreaking ceremony was held in T-shaped mouth of Xin 'an Town, marking the official start of construction of the bridge.
On April 12, 2009, the first pile of the sea-crossing bridge was successfully laid, and the construction of the sea-crossing bridge entered a comprehensive construction stage.
On July 18, 2009, the pile foundation project of the main bridge of the bridge was officially drilled, marking the beginning of construction.
On August 3, 2009, after 100 days of intense construction, the trestle of the sea-crossing bridge was fully connected, and the construction of the sea-crossing bridge was fully transferred to the main bridge construction stage.
20 10 On June 23rd, the first giant pile cap box of the sea-crossing bridge weighing more than 200 tons was successfully sleeved on the 15 underwater pile.
20101010.2, the sea-crossing bridge entered the tower column construction stage of the main bridge, which is also the most important construction stage in the construction of the main bridge.
20 1 1 27/month, more than half of the tower columns with the highest technical content were constructed. The tower construction of the sea-crossing bridge is divided into two parts: the upper tower and the lower tower. After completion, an inclined zipper will be installed between the tower column and the bridge deck, which can help the bridge deck to bear the force. The higher the tower column construction, the higher the difficulty coefficient.
12, 17, when the side span of the main bridge is 16 meters, it can be closed with the approach bridge, and when the middle span of the main bridge is 34 meters, the bridge will be fully closed and the countdown will begin.
On April 2012 13, cement was poured in the last two meters of the bridge deck, marking the official start of the closure project of the sea-crossing bridge.
201may 2 1 day, the last work before the acceptance of the bridge-bridge load test, 16 engineering vehicles with a load of 30 tons get on the bridge at the same time to "check" their quality.
Officially opened to traffic
20 12 At 9: 00 am on May 28th, the sea-crossing bridge was officially opened to traffic. No opening ceremony or celebration was held in any form, and the bridge was officially opened only through news media announcements.
The significance of traffic opening
1. The completion of the cross-sea bridge not only greatly facilitated the travel of citizens, but also further promoted the construction of the Shandong Peninsula Blue Economic Zone, providing more convenient traffic conditions for Haiyang to successfully host the third Asian Games. In addition, the construction of Shandong coastal corridor will be further promoted, and Haiyang will be more convenient to Yantai, Qingdao and Weihai, and the distance from Haiyang to Qingdao will be shortened to within 1 hour, which will provide more convenient transportation conditions for Haiyang to successfully host the Asian Games. At the same time, the completion of the cross-sea bridge and coastal highway will accelerate the docking of coastal highways in Yanqing and maintaining stability, and accelerate the pace of construction of peninsula urban agglomeration.
2. After the bridge is opened to traffic for free, it will bring more passengers to Haiyang tourism market. The coastal tourism resources of Haiyang and Qingdao can complement each other, and free transportation will attract more Qingdao citizens to Haiyang go on road trip. Haiyang and Qingdao, Yantai, Weihai and other cities form a 1 hour living circle.
There are thousands of acres of vegetable and melon gardens along the coast of Haiyang. In the past, due to inconvenient transportation, it was not convenient to transport it to Qingdao. After the opening of the bridge, a large number of agricultural products and fruits will be transported to Qingdao quickly, forming market exchanges and promoting the complementarity of agricultural products between the two places.
The traditional route from Haiyang to Qingdao is divided into expressway and first-class highway. The planned route of expressway is from Shenhai Expressway to Nancun Interchange, and then to Qingdao City via Qingxin Expressway, mainly a expressway. The whole journey takes about 3 hours. The main feature of this route is the long driving distance. The planned route of the first-class highway is 204 national highway (Yanqing first-class highway) to Liuting interchange, and then from 308 national highway to Qingdao city. The whole journey takes about 3.5 hours. The main feature of this section is the complex road conditions, and the speed is slow when passing through several urban intersections. After the bridge is opened, the journey will be shortened from several hours to one hour, and the current traffic pressure on Yanqing Highway will be effectively alleviated.
