A press conference for the east-west extension project of Haibin Road was held on September 10. The spokesmen from the project authorities and contractors made reports on the construction background, overall situation, highlights, and the latest progress of the project and answered questions of the reporters. .
Project background
The east-west extension project of Haibin Road is the largest municipal bridge project in our city, based on the current traffic conditions in Daonan area, the transformation and upgrading of Xigang district, the express road network layout of “two ring roads and four streets”, and the plan of “building Daonan area into a cruise port, a national health and tourism attraction, a meeting hall for Hebei, and model for civilized Qinhuangdao”.
The Municipal Party Committee and the Municipal Government attached great importance to the construction of the project, and regard it as a basic project and highlight for the construction of “a strong coastal city, a beautiful port city and an international city” in the new era, and have listed it as the people’s livelihood project for two consecutive years.
Introduction
The total length of the road is 10.28 kilometers, the estimated investment is 1.928 billion yuan, the total length of the bridge is 4.45 kilometers, and the length of the steel structure bridge is 680 meters. It is the municipal road and bridge project with the biggest amount of investment, the most advanced technology, and more traffic influence in the urban area so far.
The project consists of two parts: the existing Haibin Road extends across the port railway and Datanghe river and Xiaotanghe river to Lingqian Street in the west, and extends across Minzu Road and the port railway to Donggang Road in the east to form a main urban road, building 2 overpasses and renovating 2 sections of existing roads; the existing Xigang Road extends to the south, crossing Hebei Street and the national railway entry and exit lines to the Xigang district.
Functions
It has 4 functions after the project is completed:
Add an east-west traffic passage in the southern urban area; improve urban road network system; relive the pressure of cross-boundary traffic; and add a convenient passage connecting Shanhaiguan and Beidaihe.
Add an external channel of the port area to drive the transformation and upgrading of the Xigang district.
The project will be convenient for 150,000 people living in Daonan area, with the newly-built north-south and east-west passages, relive the traffic pressure on the urban roads of “one horizontal and four verticals”, and improve the overall urban traffic carrying capacity and image. “One horizontal” is Hebei Street; and “four verticals” are Wenhua Road, Youyi Road, Hongqi Road, and Xigang Road.
Highlights
In the process of design and construction, the scientific and technological means, new technologies and techniques are adopted, and many breakthroughs in municipal bridge project have been achieved.
Five Firsts
For the first time, uniform section steel box girder and variable section steel box girder were used in municipal bridge project;
For the first time, the suspension pouring process was used on the iron viaduct bridges;
For the first time, the BIM technology was used to conduct intelligent, integrated and refined management of the whole process of engineering design and construction;
For the first time, the embedded chip electronic monitoring technology of concrete test block was used to fully supervise the quality of concrete;
For the first time, the construction waste recycle has been realized. The pavement bricks of approximately 60,000 square meters of the project are made from 15,000-square-meter solid construction waste.
Latest progress
Up to now, the demolition work has been basically completed with the exception of the Zhongtu Nengyuan gas station, with a total of about 45,000 square meters of structures demolished. More than 50 integrated pipelines (about 400 pipelines) relocated and protected, and high-voltage line demolition completed. The construction of the two bid sections has started on the whole line, and the steel box girders of the viaduct bridges across the Datanghe River and Hebei Street have been completed.
The south extension of Xigang Road has been ready for opening to traffic. The auxiliary road on the south side of Haibin Road section from Youyi Road to Wenhua Road has been completed and opened to traffic, and the construction of the bridge across the railway on Xigang Road has been completed. The accumulated investment is about 1.35 billion yuan, accounting for 73% of the total. The main line of overall project will be completed by the end of the year.
We are looking forward to the early completion of this livelihood project that will benefit the people of Qinhuangdao, and polish the business card of “a strong coastal city, a beautiful port city and an international city”.
