The clean energy industry has become a strategic emerging industry that the country prioritizes in supporting development. The development of liquefied natural gas (LNG) has become a key measure for China's energy transformation, which will not only effectively promote the vigorous development of China's natural gas industry, but also deeply promote the transformation and upgrading of China's energy, playing an important role in building a green, low-carbon, and sustainable energy system in our country.
With the continuous promotion of the "dual carbon" target, China's natural gas consumption is constantly increasing. Against the backdrop of strong natural gas supply and demand, domestic LNG receiving stations may usher in a wave of production by the end of the 14th Five Year Plan period. Jianhua Building Materials, with its outstanding technical strength and innovation capability, provided an integrated solution of "pile+component full assembly" for Sinopec Tianjin LNG and Yantai Longkou LNG projects. The plan integrates green and environmentally friendly engineering concepts with convenient and efficient construction techniques, fully demonstrating its responsibility and technological leadership in the field of clean energy.
Coastal engineering presents numerous challenges
LNG projects often need to face the harsh environment and complex geological problems unique to coastal areas. At the same time, while ensuring engineering quality, there are often strict requirements for project duration and appearance quality. How to solve the problems of strong corrosion and pile sinking in foundation piles, how to avoid wet operations on site in the upper structure, and how to ensure the installation accuracy of prefabricated columns and beams are all core problems that urgently need to be solved.
Optimize coastal construction plan
In response to the durability and pile sinking issues of foundation piles, pencil pile tip sealing technology was adopted to meet the durability requirements while solving the problem of pile penetration. The upper structure support adopts precast concrete columns and beams, which are free of formwork and support on site. The construction process is fast, efficient, green and environmentally friendly, and the appearance achieves the effect of plain concrete. Maintenance free during use, reducing later costs.
Tianjin LNG Project
Yantai LNG Project
The two projects simultaneously adopted the latest "fully bolted connection assembly construction technology" developed by Sinopec, effectively avoiding on-site wet operations, improving installation efficiency, saving labor, and having significant economic advantages.
At the technical level, the Jianhua Building Materials team is deeply involved in the entire project process, maintaining close communication with all parties and providing precise and effective technical support. During the construction period of the project, professional technicians always serve the construction site, monitor key links such as pile foundation construction and upper component installation in real time, provide solutions, overcome process difficulties, and ensure the smooth progress of the project.
Green Navigation Service Innovation
Jianhua Construction Materials always adheres to the service principle of "genuine materials, timely delivery, and dedicated service", wholeheartedly providing customers with a full chain, one-stop solution covering research and development, design, procurement, manufacturing, logistics, construction, and service. At the same time, we actively practice the concept of green and low-carbon development, vigorously promote the deep integration of industrial infrastructure construction and low-carbon energy conservation, and vigorously promote the green development of the industry through technological innovation, continuously contributing to and adding glory to engineering construction.
