Constructing tunnel lining device is broadly divided into side and roof arch formula, whole-circle needle beam type, bed die needle beam type, wholecircle traveling type etc.,
It is supported when for being excavated to tunnel main body, but existing side and roof arch formula constructing tunnel lining device is poured using loaded concrete
It builds and has the following problems:
1. constructing tunnel lining device is when being filled loaded concrete, since the main component in loaded concrete is that weight is brilliant
Stone and iron ore, barite and iron ore content in concrete mostly can the template constantly to constructing tunnel lining device hit
It beats, shutter vibration is caused to deviate, and it is unbalanced to receive concreting at the top of the arc formwork after deviating, it may occur that top die
Plate compressive deformation is even beaten the phenomenon that collapsing.
2. and tunnel form is pushed in the tunnel of excavation by constructing tunnel lining device, after manually carrying out lining cutting,
Waiting eight could demould to twenty four hours, however wait the process of demoulding due at tunnel excavation in water rock stratum, underground water
Because the presence of pressure difference is constantly oozed out, the underground water of exudation is extruded into the arcuate end of side and roof arch formula lining device, causes side
The tunnel form of lining cutting is insecure in the arcuate end of crown formula lining device.
