The important channel connecting the two provinces of Zhejiang and the Soviet Union -Pingli Highway span over 100 meters of bridges!

On July 7th, the hot sun and heat were unbearable. In the Hongqitang waters of Hangshen Line, the main span of the Xitang Bridge across 100M steel mixed Liangliang went smoothly, marking the investment of the Shanjiang Highway Project Co., Ltd. of Jiashan County, the subordinates of Jiashan County Construction and Zhejiang Transportation Group under the construction of the Pingli Highway Jianshan section reform (expansion) construction project (expanded) project (expansion) project (expanded) project (the east side section of Zhenbei Road to Luxutang Bridge) project (hereinafter referred to as "Lu Duan" ) Significant progress in the construction of key nodes has provided important guarantees for subsequent main lines.

At the end of 2020, the Lu section project of Pingli Highway started successfully. It is understood that the project's route has a total length of about 7.765 kilometers, set up 11 bridges and 4 culverts, rebuild 1 three -dimensional intersection, 8 plane crossings, with a design speed of 80km/h, a total investment of 790.5183 million yuan, and the planned construction period is 24 A month.

This project is an important part of the reconstruction and expansion project of the Jiashan section of Pingli Highway. It is a cross -provincial channel connecting the 318 National Highway of Zhapu Port in northern Zhejiang Province and Zhejiang, Zhejiang Province. Key project. After the project is completed, it will greatly improve the quality of road traffic, alleviate local traffic pressure, improve the regional road network, open up the county and district connection to large arteries, connect the Shanghai -Zhejiang and Zhejiang places, and help promote Jiashan to "integrate Shanghai into the Yangtze River Delta" strategy.

Fine planning, span 100m steel mixed and overlapping beams

Go smoothly

The Xitang Bridge is a key control node project across the Lu section project of Pingli Highway. The main span of the bridge has a maximum span of more than 100 meters. The same type of bridge has only three or four in the country. Its technical difficulty can be imagined.

Due to the particularity of the process, the construction must be carried out under the condition of navigation. On July 1, the project department invited the Jiashan County Transportation Bureau to hold a safety interchange of traffic control construction traffic control. Organize technical personnel and team to hold a special safety technology intersection, and segment the responsibility of construction technology and security measures.

At the same time, with the help of the Jiashan County Maritime Bureau, the project department leased six sealing ships and one emergency rescue boat to install emergency lights and other facilities in the hull to make full preparations for the safety of air sealing. In addition, the maritime department also arranged three squat points on the east and west side of the film and around the Xitang Bridge, as a water traffic police protection construction safety.

In the early stage of work, the construction can be successfully entered. On July 5th, the construction of the seal was officially opened. "Sanfu Tian" is cool, which is a huge challenge for everyone.

Because the large span steel beam of the Xitang Bridge adopts a fully weld structure, there are various forms of joints and welding points in different positions inside, and the welds are high and the welds are dense, especially at the support of the support. Therefore, ensuring welding quality, controlling welding residual stress and welding deformation are major difficulty in welding of steel beams.

"The effect of temperature on the steel structure is very large, so our measurement work must be strict and meticulous." Guo Enhui, director of the Xitang Bridge Industry Zone, introduced that according to the daily temperature changes, the highest and lowest temperature differences, the number of phase relationships is calculated. The work needs to be completed because each steel beam must be repeatedly measured to ensure the accuracy of welding.

With the collective efforts of the project department, the construction work under the bridge was quickly and accurately completed during the three -day sealing period, laying a solid foundation for the Xitang Bridge Double -Around and other node tasks.

Scientific organization, do a section of acceptance and acceptance

The Lu section of Pingli Highway Town is an important main road connecting Jiashan City and Xitang Scenic Area. On the one hand, the traffic pressure of residents commutes, on the other hand, it is also adjacent to the Shenjia Lake high -speed port. The rods (tube) lines, shops and residents are lined up. It also involves the Hongqitang waters of Hangshen Line. It is a typical "three links" project for the construction of the edge of the edge of the border.

"Because of the tight construction period, we can only do one section of acceptance and one section." Ye Bin, the person in charge of the project, said that the traffic organizations at each stage will encounter various conditions. Three times. Because once construction starts, there will be a greater impact on the travel of the surrounding residents, and there will be many unpredictable safety hazards. Therefore, how to coordinate the contradictions before construction and traffic have become the primary consideration of the project department.

In order to minimize the impact of engineering construction on social traffic as much as possible, with the help of the construction unit Jiashan County Shanjiang Highway Project Co., Ltd., the project department actively communicated with the transportation and traffic police and other departments to formulate a complete set of traffic organization solutions. "We have invited a dozen of more than a dozen." Ye Bin said that safety issues are prerequisites for engineering construction, and the cost of spending in this area cannot be reduced. As of now, the project has invested more than 8,000 isolation water horses, more than 300 signs, and more than 300 safety warning lights at night. At the same time, special personnel are arranged to assist in the traffic management department for traffic management.

It is worth mentioning that in order to reduce the impact of construction on the surrounding environment, the Lu section project of the Pingli Highway Town actively responded to the country's environmental protection call during the construction process, and specially arranged dried cars. Compared with the general sewage vehicle, dry car washing is known as the road "Vacuum King", which can not only force up the buildings of the ground's adhesion and cokcelasses such as the ground. The most important thing is that there will be no dust during the operation. Prevent and reduce pollution problems.

Leading party building, "Sword" assault project

Open at the end of the year

The party building work is not only the "navigation lamp" and "catalyst" of engineering construction, but also the source of vitality and kinetic energy of the project. Since the beginning of the construction of the Lu section project in the town of Pingli Highway, the project department has deeply integrated the party building and the construction of the project, giving full play to the role of party members to attack the team, and building a strong combat fortress for the work of service engineering construction centers.

Earlier this year, the production of project production ushered in the most critical and difficult moments. The target tasks of the two nodes were arduous. To this end, the project department specifically established the "Sword Commando". The assault teams are divided into five groups, and the five major groups correspond to five important industrial areas. The person in charge of the production strip line will issue tasks to segment the task to individuals, and specifically until the month, week, and day. At the same time, the "5S" management model is adopted to conduct performance assessment of assault players and related work areas, mobilize the enthusiasm and enthusiasm of employees, and lead the project project smoothly.

The epidemic has become a topic that has not been opened in the past two years. Since the construction of the Lu section project of the Pingli Highway, although the construction period has been affected by the epidemic, it still has a lot of volunteer services for the society. At the beginning of May, the project department received the notice of supporting the water horse support, and immediately organized the young party members to consider the collection of a sufficient amount of water horses, and quickly loaded the vehicle to dispatch. Task.

In addition, during the Typhoon "Fireworks", the young party members of the project department also shouldered the work of the work zone, equipment maintenance, and power safety inspection. In the construction area of ​​Linhe -related River, they worked together to use sand bags to strengthen the dam and conduct 24 -hour inspections to clean up and repair the hidden safety hazards across the board.

Doing the work of practical party building and exerting the benefits of the party building is the key lies in the first line and the grassroots. Through the development of a series of theme activities, the role of the party organization's fighting fortress is even more prominent, and the role of the pioneer of party members is more prominent. The project department of the Lu section of Pingli Highway Town has really improved the progress, quality, and safety in terms of project progress, quality, and safety, and laid the foundation for the establishment of the entire line at the end of this year.
