Piece II, the stator II at elastic supporting bar two ends is respectively arranged at surface and internal tunnel external surface in outer tunnel body
The drawbacks of overcoming prior art the utility model has the advantage of it, reasonable in design is novel.The application's
Design is provided with some nylon wires in silica gel waterproof layer, increased the tensile capacity of silica gel waterproof layer, and the setting of nylon ball is caused
Nylon wire and silica gel waterproof layer internal friction, improve supporting function of the nylon wire for silica gel waterproof layer.When tunnel matrix portion
Divide after deforming, outer tunnel body bears pressure and slight deformation occurs, now between internal tunnel body and outer tunnel body
The fine sand filled in space serves the effect of buffering, prevents deformation force from having influence on internal tunnel body, improves the resistance to compression in tunnel
Ability.But the outer surface unbalance stress of internal tunnel body at this moment can be caused, the service life of internal tunnel body is have impact on.Pass through
The sidepiece that elastic supporting bar supports internal tunnel body is set, and outer tunnel is so worked as at the top of tie-strut support internal tunnel body
Body is deformed or during displacement, and adjustment internal tunnel body used by the pulling force and thrust supported by elastic supporting bar and pull bar is existed
Position in outer tunnel body, and then the stress that outer tunnel body is put on internal tunnel body by fine sand is adjusted, make stress
Uniformly.Strip bulge is prevented from the stress spread of tunnel matrix, and strip bulge can by with outer tunnel external surface
The tunnel matrix of contact plays support effect, prevents the tunnel matrix contacted with outer tunnel external surface from occurring to loosen and cause
Bigger landslide.
