Urban pipe network construction——trenchless technology, make the city better

China International Power Group has a number of core technologies (patents and construction methods) for urban pipe network construction, and has a lot of practical experience in the non excavation field of small and medium-sized professional pipe network and comprehensive pipe gallery construction.

With its leading technology, China International Power Group can provide integrated solutions for small and medium-sized professional pipe network and utility tunnel, and can customize the radial shield machine for specific projects to adapt to the characteristics of the project; it can provide a wide range of services, including pipe network linear design, shield machine selection, shield machine and trenchless equipment design and manufacturing, steel mold and steel pipe sheet design and manufacturing, tunnel construction and construction guidance Integrated solutions, committed to trenchless technology research, and strive to provide customers with intelligent, safe, efficient, economic and environmental protection construction experience.

1、Patents and construction methods

1、Synchronous tunneling method：Compared with traditional shield construction, synchronous tunneling can improve efficiency by 30-50%；

2、Three mode shield construction method：The three modes of mud water, earth pressure and mud concentration can be applied to various strata, and can be changed without changing the knife for a long distance. It is especially suitable for the low coverage soil and pebble geology of city pipe network, and is more safe and efficient.

3、FS construction method：Shield machine can not only be used as pipe jacking machine, but also as shield machine. It can be switched naturally without working shaft. On the one hand, it can improve the utilization rate of equipment, on the other hand, it can improve the construction efficiency and reduce the construction cost;

4、Mud pressing and discharging method：Quick dumping, no pipe blockage, cleaner site and easier operation;

5、Tunnel before well：Fast construction, low risk, small occupied space, modular construction;

6、Bolt free segment：Realize fast and automatic assembly, especially suitable for tap water and sewage pipe network, avoid hand hole plugging.
