H&V(Horizontal & Vertical) TBM<\/h3>\n\n\n\n

H&V means Horizontal variation & Vertical variation.
The feature of H&V TBM are; \u2460independently controlled circular TBMs that are connected each other with flexible joint.\u3000\u2461Each TBM can be disconnected in the ground as needed.\u3000\u2462Cross articulation system allows spiral advancing movement and as a result, the position of each TBM can change from a top and bottom line to right and left line.<\/p>\n\n\n

T-BOSS method (T-type basement Branch Off Shield System)<\/h3>\n\n\n
\n
\n\"\u23004.19m\n<\/figure>\n
\n\n\n

It is one of the methods to connect the excavating tunnel to an existing tunnel. It has a built-in steel cylinder driven by cutter head driving power.
The steel cylinder has special cutter bits and bore through the existing tunnel wall, either steel segments or reinforced concrete segments. While advancing forward, the tunnel wall of TBM stays close to the exisiting tunnel.
The steel cylinder can resist ground pressure and water pressure, so that ground improvement work can be reduced and tunnel connection work can be done more safely and effectively.<\/p>\n\n<\/div>\n<\/div><\/div>\n\n\n

Inner Shell DSR TBM (Draw a Shield for Recycle system)<\/h3>\n\n\n\n

The TBM’s external casing and internal unit are constructed as independent units, and the internal (drive) unit is removed following completion of tunneling of the first section. It is taken to the departure shaft, where a new external casing is fitted, and excavation is then begun on the next construction section. Because the TBM’s internal unit is resued, there is no need to construct an arrival shaft. The drive shaft can also be set up anywhere along the construction route.<\/p>\n\n\n

Mother and Child TBM<\/h3>\n\n\n\n

It has a built-in Child unit TBM that can be separated in the underground. As a result, the Mother unit TBM and Child unit TBM can excavate tunnels of different size. Various methods can be applied to the cutter head separation technology, depending on the conditions such as the type, size, and diameter difference of cutter head between the Mother unit and Child unit.<\/p>\n\n\n

\n\n\n

Two TBMs coming from opposite directions meet each other under the ground. One TBM has a steel cylinder pushing forward to the other machine. Another TBM has rubber ring jointing with the cylinder. The steel cylinder and rubber ring can shut off soil and ground water completely. After docking, the equipment and structure inside the two machines are removed, then tunnels are jointed.<\/p>\n\n<\/div>\n<\/div><\/div>\n\n\n
