The Shenyang-Kangshan Connector Expressway (hereinafter referred to as the "Shenyang-Kangshan Connector") is located at the northern end of Shenyang, the central city in Northeast my country，As a ring line connecting central Liaoning、The main channel of Pingkang and Changshen Expressway，Project for breakthrough in northwest Liaoning、The integration of the development of the central Liaoning urban agglomeration and the overall revitalization of Liaoning play an important role in guiding land transportation。As a safety standardization pilot and a typical demonstration project for steel structure bridges in the "Two Districts and Three Factories" quality engineering research action of the Ministry of Transport，Shenkang connection line in system and structural innovation、Steel structure bridge demonstration、Component standardized design、A series of key technologies have been formed in construction technology research and information management，Integrated promotion of high quality and durability、Ecological harmony、Economic and environmentally friendly、Ecological harmony、High-quality highway project construction recognized by society。

First, insist on quality first，Promote ingenious manufacturing。The beginning of project planning and construction，The construction unit is based on the construction and management advantages of Liaoning Expressway’s “Four Unifications”，Comprehensive summary of highway project construction management experience in Liaoning and northern regions，Completed the first Liaoning Province Expressway Project Construction Management Planning Outline，Coordinate the whole process construction management of the project，Relying on the project, we actively participated in the compilation dafabet live casinoof industry standards such as the Ministry of Transport's "Technical Requirements for Safety Production Conditions of Highway Water Transport Engineering"，Strive to promote the Liaoning pilot project of the Ministry of Transport's quality project "Construction Safety Standardization in Two Districts and Three Plants"，High standard built project factory and station，The "Safety Standardization Guidelines for the Construction of "Two Districts and Three Factories"" was summarized and published，Scientifically formulate the "Implementation Plan for Deepening the Quality Engineering of the Shen-Kang Connection Line Project", etc.，Decompose and clarify 14 key research topics including "research on anti-drainage technology for cement concrete bridge decks on highways in cold areas"，Strive to implement and complete all the Ministry of Transport's "Quality Engineering" research tasks，And apply technologies such as hot-rolled steel composite beams and prefabricated pier cap beam structures，Actively carry out research and practice on the application of prefabricated bridges，Summary and formulate technical standards for steel beam welding quality and construction accuracy、Control requirements，Effectively ensuring the steady improvement of the quality and durability of the bridge structure。

The second is to adhere to energy conservation and ecology，Promote green environmental protection。Shenkang Connecting Line always adheres to ecological and environmental protection、Construction concept of green development。As the first batch of steel structure demonstration projects of the Ministry of Transport，The project is based on reality，9 pilot bridges including the Yalujiang Street Hub Overpass Ramp B Bridge were selected to carry out in-depth research and application on bridge durability，The 50μm~100μm thickness density formed by the weathering steel surface of the bridge steel-concrete composite beam component、A protective film with strong adhesion，Greatly protects the matrix under the rust layer on the steel surface，Significantly improve the atmospheric corrosion resistance of dafabet live casinosteel materials，The bearing capacity and service life of the bridge are more than 10% higher than that of ordinary concrete bridges；The whole bridge adopts painting-free technology，We will try our best to minimize the pollution of the ecological environment，The bridge has reached its service life，Steel plate material can be recycled again，Better realization of green environmental protection and recyclability。During the implementation process, we continuously summarized and formed technical documents such as "Steel Beam Construction Supervision Procedures and Technical Requirements", "Steel Beam Testing and Inspection Implementation Rules", "Research on the Corrosion Resistance Mechanism of Weathering Steel and its Welds"，Provide useful reference for the construction management of Liaoning weathering steel-concrete composite girder bridge。Because the expressway crosses the Shenyang Puhe Wetland Ecological Corridor，In the process of project implementation，Further strengthened the protection and utilization of native vegetation and topsoil，Use topsoil stripping to reduce ecological damage and soil erosion，And scientifically implement ecological green operations across the Pu River Basin，Effectively reduce the adverse impact of construction on the ecological environment。The project construction actively plays the role of pilot factories in applying and testing the results of the "Two Districts and Three Factories" standard guideline，Insist on eternal union，Coordinate project site and site area，Present area station、Construction sites give priority to sewage sedimentation、Dust Monitoring、Advanced equipment such as spray dust suppression、Measures，Successfully avoided construction pollution。

The third is to persist in innovation and development，Improving the level of construction management。In order to further optimize the production method and management model of Liaoning expressway construction，Shenkang Connection Line independently developed the "BIM+Internet+IoT+Big Data" technology construction management platform，Promote dafabet casinothe integrated application of BIM technology in the entire life cycle of highway construction，And supporting the development of quality inspection web client and mobile APP client，Enable on-site quality inspection data to be entered more conveniently，To steel bars、Production of concrete components, etc.、Installation uses QR code information for scanning and verification，Ensure real-time collection of project site data and information、Efficient analysis、Timely release and ready access，Realize real-time collaboration and in-depth exchange of construction data and information between different participants on the construction site。At the same time，Use BIM technology to carry out construction simulation、Three-dimensional visualization technology briefing、Service area architectural three-dimensional display and landscape design tour, etc.，Further strengthening project management decision-making，Lay the foundation for comprehensive improvement of project management efficiency。

The fourth is to adhere to standard management，Ensuring safe construction。In order to strengthen the "three bases" construction of Liaoning expressway construction industry，Carry forward the "craftsman spirit" in the field of transportation infrastructure construction in the new era，Shenzhen Kang connecting line project from steel bar processing、Beam and slab precast、pier column cap beam、Bridge Deck System、Implement standardized team management for the entire line such as roadbed construction，Strictly implement the admission system、Qing and withdrawal system、First piece system，Based on team and group，Clear the various types of work、Process standards and operating procedures for each position，Establish team leader、Technician、Safety Supervisor Standard Team Internal Management Responsibility System，Do a good job before class、Class、Prescribed actions after class，Unified team management in the industry，Form a complete and feasible team management system and assessment and evaluation mechanism，Effectively transform frontline discrete dafabet best online casino“migrant workers” into “industrial workers”，Overall improve the refined construction level of front-line workers，Further matching the high-level personnel needs of "factory manufacturing"，Resolve shortcomings in construction standardization and safe construction sites。

While doing a good job in the “last mile” of quality and safety，Highlight the guiding role of party building work in project construction management，Established the province’s first “4+N” project joint temporary party branch for highways，Put the project construction unit、Central Laboratory、Design unit、A total of 33 party members from 4 relatively fixed units in the supervision unit and N relatively mobile construction units are included in the dynamic unified management，Do not change the relationship between party members and party organizations of each participating unit，The first project to build a “big party building” at the grassroots level，Build a progressive “Communist Party Member Pioneer” creation system with “points, lines and planes”，Control the project、Nodal Project、Demonstration pilot work、Integration of emergency capacity building and Communist Party member pioneer project，Achieve effective results in promoting production through party building。
