Normal high-density slurry type pipe jacking machine
This is a type that can be used within the range applicable to the conventional high-density slurry type pipe jacking method.
It also supports long-distance and sharp curve pipe jacking.
TBM with a pipe diameter of φ800 to φ1350 mm can be launched separately from a small shaft, realizing space-saving construction.
Boulder compatible TBM
Take in whole gravel with primary crushing and large diameter slurry discharging pipe!
Boulder compatible TBM
It fully supports gravel and boulders with a pipe diameter of 100%, which could not be discharged by the conventional method, and has achieved crushing with a unconfined compression strength of 300 N / ㎟.
This makes it possible to deal with boulder and cobbled stone layers, greatly improving safety and workability.
By performing only primary crushing and taking in the whole gravel with a large-diameter slurry discharging pipe,
there is no energy loss, so efficient soil discharge is possible.
Equipped with a crushing type function (roller bit) manufactured for the purpose of constructing for boulder and cobbled stone layers.
As a result, the cutter enables stable excavation with high torque and high rotation.
You can also select the bit type according to the gravel diameter and gravel strength.
The TBM with a pipe diameter of 800 to 1000 mm can be launched separately from a small shaft,
and space-saving construction can be realized by retrieving the arrival side with the minimum division.
When the pipe diameter is 800 mm, it is possible to construct with a driving shaft φ3.0 m and a reception shaft φ1.9 m.
Disassembly and retrievable type TBM
Realization of launching and arriving by the minimum size of shaft!
Disassembly and retrievable type TBM
In addition to long-distance and sharp curve pipe jacking, which are the characteristics of the high-density slurry type pipe jacking method, it is possible to launching and arriving in a small shaft and retrieve TBM from an existing manhole.
Since all of TBM can be disassembled and retrieved, it contributes to environmental conservation without leaving the shield in the ground.
TBM with a pipe diameter of 800 to 1000 mm can be launched separately from a small shaft, and space-saving construction can be realized by retrieving the arrival side with the minimum division.
By adopting the disassembled structure of the machine unit, it is possible to retrieve from the existing manhole with an opening of φ600 mm.
By retrieving the machine from the existing manhole, it is possible to significantly reduce the cost.
