Recently, China Railway Co., Ltd. announced the 2023 energy-saving and low-carbon technology, and the municipal project of Fengxi District of China Railway Guangzhou Bureau Municipal Environmental Protection Company "Key Technology for Long-distance Pipe Jacking Construction of 4m Large Diameter Reinforced Concrete Pipe" was selected as a low-carbon technology.
This technology has been successfully applied to pipe jacking construction, especially suitable for various soil environments with pipe diameters between 3 5m and long jacking distances. This technology has played an important role in the construction of large-diameter pipe jacking for urban waterlogging control, and has also been widely used in projects such as urban comprehensive pipe corridors passing through existing roads. Compared with the traditional slurry balance construction method, this technology significantly reduces the amount of earthwork slag and effectively reduces the consumption of resources such as electricity and diesel.
The application of this technology greatly reduces the construction safety risk, reduces the investment in basic measures, reasonably saves labor and construction period, greatly saves costs, and has won a good reputation for the enterprise and the project department and the praise of the owner. At the same time, it gives full play to the role of energy conservation and emission reduction in improving the quality and efficiency of project management, protects the original ecological environment to the greatest extent, fully demonstrates the concept of green, energy-saving and low-carbon modern urban construction, and creates good environmental protection, economic and social benefits.
