[0002] With the continuous development of social economy and the continuous improvement of urbanization level, TBM construction technology has been widely used in new tunnel or mine engineering. TBM is a special engineering machinery for tunneling, which has the functions of excavating and cutting soil, transporting mud and assembling tunnel lining. It has been widely used in tunnel engineering such as subway, railway, highway, municipal engineering, hydropower, etc. TBM is often used in flat tunnel construction with a slope of ≤5°, but in recent years it has also been gradually used in projects with larger slope requirements such as water conservancy and mining.

[0003] There are many technical difficulties in the construction of TBM in inclined shafts with large slopes, one of which is the reception work when the TBM is converted from an inclined shaft to a horizontal one. The invention patent with application publication number CN112412478A discloses a method for receiving the TBM from an inclined shaft to a horizontal one. A "bridge" that can rotate around a central support is set at the intersection of the inclined shaft and the horizontal tunnel. When the TBM main machine is pushed up to the "bridge", the "bridge" and the TBM main machine on it are converted from inclined to horizontal through hoisting. This method uses a larger hoisting equipment installed in the receiving room, which requires a large space in the receiving room and requires a specially designed support frame and hoisting system to meet the stability of the "bridge" structure.
