Problems of pipe jacking technology existing in China

The main problems of pipe jacking technology existing in our country is that machinery and equipment technology lag behind, regional differences, different levels, lack of standardization, lack of talent, remains to be further promotion.

The pipe jacking machine equipment in our country mainly relies on import, although the domestic production enterprises, but the pipe jacking technology is still behind the international first level, machine model types are insufficient to meet the needs of engineering, in our country there is no suitable for the strength of rock above rock plate machine, to adapt to the soil range is not wide, and durability, mechanization and automation level is not enough.

From geographically, pipe jacking technology adapt to the level of regional economy in our country, the development of our country in the eastern part of pipe jacking technology development level is much higher than the Midwest, Guangdong, Shanghai, Zhejiang, Jiangsu and Shandong provinces and cities will account for 75% of the workload of trenchless pipe laying. And the western region only in the west to east gas pipeline project is one of the few crossing pipe jacking project, the difference in the Midwest and eastern coastal areas.
