Chip is answered, the pressure sensitive chip is connect with electric cabinet.
The rubber slab is with a thickness of 12mm.
The rubber board width is 10cm.
The rubber slab compression deformation is 2~3mm.
The rubber slab is fixed by fixing bolt, and the fixing bolt is arranged along two lining trolley circumferential direction directions.
It is 2mm that the rubber slab, which is higher by two lining trolley steel templates,.
The rubber slab is provided with semicircle rubber sealing end close to a upper plate two lining end.
The semicircle rubber sealing end height is 10mm.
The semicircle rubber sealing end modulus of elasticity in comperssion is 5~8mm.
The pressure sensitive chip be it is multiple, adjacent pressure sensitive chip circumferential direction spacing be 1m.
Compared with prior art, the beneficial effects of the present invention are:
1, the rubber slab in the present invention can protect concrete edge not ensure that two plate two of tunnel serves as a contrast by two lining trolley squeeze cracks
Lap-joint's presentation quality and entity quality between concrete.
, semicircle rubber sealing end can ensure tightly to be bonded between concrete and rubber slab in the present invention, form sealed end,
Ensure do not occur overflowing slurry spillage.
, the present invention in by electric cabinet read pressure sensitive chip pressure sensitive value, when the value close to a upper plate two serve as a contrast mix
When solidifying soil resistance to compression value, stop top and stretch, thereby further ensures that a plate two serves as a contrast concrete in not capping；And realize visualized operation,
Meet construction demand.

Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 3, a kind of soft lap device of tunnel double-lining end head formwork pressure visualization, including two lining 1 Hes of trolley
Electric cabinet, the two lining trolley 1 have been additionally arranged at the bottom rubber slab 3 close to the lapping plate 2 that a upper plate two serve as a contrast, the rubber slab 3 and
The two lining arc length on circumferential direction of trolley steel template 5 are consistent；Pressure sensitive chip 7, the pressure are installed on the rubber slab 3
Induction chip 7 is connect with electric cabinet.
Referring to Fig. 1 to Fig. 3, further, the rubber slab 3 is with a thickness of 12mm.
1, referring to Fig. 1 to Fig. 3, further, 15cm of the usually existing two lining trolley 1 close to a upper plate two lining end is
Lap position, therefore selecting 3 width of rubber slab is 10cm.
Referring to Fig. 1 to Fig. 3, further, 3 compression deformation of the rubber slab control is 2~3mm.
Referring to Fig. 1 to Fig. 3, further, the rubber slab 3 is fixed by fixing bolt 4, the fixing bolt 4
Along two lining 1 longitudinal direction of trolley arrangements, adjacent 4 spacing of fixing bolt is 100cm on circumferential direction.
Referring to Fig. 1 to Fig. 3, further, it is 2mm that the rubber slab 3, which is higher by two lining trolley steel templates 5,.
Referring to Fig. 1 to Fig. 3, further, the rubber slab 3 is provided with semicircle rubber envelope close to a upper plate two lining end
End 6.
Referring to Fig. 1 to Fig. 3, further, it is 10mm, semicircle rubber herein that the semicircle rubber, which blocks 6 height,
Glue blocks 6 height and refers to that semicircle rubber blocks the maximum distance between 6 outer surfaces and rubber slab 3；And the semicircle
It is 5~8mm that rubber, which blocks the control of 6 moduluss of elasticity in comperssion,.It is Nian Jie using glue between semicircle rubber sealing end 6 and rubber slab 3, half
Round rubber sealing end 6 is for ensuring that soft overlap joint end is not in spillage phenomenon.
