Specific embodiment
The preferred embodiment of 1 to 11 pair of the utility model is described further with reference to the accompanying drawing, including trestle main body 1,
It further include full width trolley 2, full width inverted arch template 3, monoblock type central trench template 4, inverted arch layer sealing end template 5, filled layer block mould
Plate 6；
Full width trolley 2 is walked by motor along trestle main body 1 certainly, and the oil cylinder of 2 bottom of full width trolley passes through otic placode 9 and full width
Inverted arch template 3 connects, connection and driving mechanism between trestle main body 1 and full width inverted arch template 3,
The arc of full width inverted arch template 3 is bonded the tunnel section of excavation completely, and full width inverted arch template 3 is by camber line template group
31, circumferential beam 32, longitudinal beam 33 form；The setting of camber line template group 31 is arranged in circumferential 32 bottom of beam, longitudinal beam 33 in circumferential beam
32 top；
31 integral construction of camber line template group splits construction, and the working face of camber line template group 31 offers working window, longitudinal
The rear and front end bottom of beam is provided with demoulding oil jar；
The front end of full width inverted arch template 3 is arranged in inverted arch layer sealing end template 5, and filled layer blocks template 6 and monoblock type center
Ditch template 4 is connected to the rear end of full width inverted arch template 3；
It is whole with full width inverted arch template 3 that inverted arch layer blocks template 5, filled layer sealing end template 6, monoblock type central trench template 4
Forward.
When work surface construction, filled layer sealing end template 6 and monoblock type central trench template 4 are connected to 2 rear end of full width trolley, and
It is driven and is moved forward by full width trolley 2.
The utility model provides a kind of completely new technical solution:
