There are many obstacles, counteracting each other, during the construction of long tunnel, such as various working procedures, limited construction period and incommodious operating space due to the narrow transect. Moreover, the inconstant geology decides various operation parameters applying to either drill-and-blast method or TBM method, which, in turn, enhances the difficulties.

长隧洞TBM施工条件复杂，开挖工序繁多；开挖断面小，工作空间有限，施工中各工序之间相互制约、相互干扰；地质条件多变，采用隧道掘进机开挖需要针对隧洞的具体情况采取不同的施工措施，给施工管理带来一定的难度。

HCG's TBM assembly workshop is capable of 12 TBMs with diameters more than 6.0 meters in a year. HCG assembles tunnelling systems which are individually adapted to the tunnelling projects and their specific geological and hydrological conditions. The product portfolio covers Hard Rock TBMs, Open-Face Shields, Earth Pressure Balance Shields and Mixshields for Traffic Tunnelling.
