Arranging formwork support structure is: support across being supported between symmetrical half range template using truss as top cross, described truss is in falling " ware " font, the wing bar that two ends, truss top are stretched out is supported in the top longitudinal beam of chassis, the end of described wing bar is provided with adjustable connecting-rod, described adjustable connecting-rod is along adjustable length on the bearing of trend of wing bar, and the front end of described adjustable connecting-rod is connected on the bottom back of the body rib of the arch template of corresponding side; Carry on the back between rib with the stage casing of the side wall template of corresponding side at the two ends of described truss and oblique dowel bar is set; Vertical shore is set between described truss and arch template, overall " cave " character form structure forming large headroom.
The present invention's large headroom tunnel lining trolley formwork bracing system, its feature is also:
Between the epimere back of the body rib and the rod end of wing bar of described side wall template, hound is set;
Between the hypomere back of the body rib and tunnel ground of described side wall template, lower hound is set;
Waist strut is set between the waist and side wall template of described oblique dowel bar and forms trivet.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, template split is set to symmetrical half range template by the present invention, eliminate chassis inner upright mounting, unnecessary stress is born as top cross support by truss, and provide top operational space, overall " cave " character form structure forming large headroom, effectively increase headroom under chassis, reduce security risk, improve constructing tunnel efficiency.
2, sound construction of the present invention, is convenient to dismounting and adjustment.

Detailed description of the invention:
See
fig. 1, in the present embodiment, the form of structure of tunnel lining trolley adjustable formwork is: on the tunnel cross-section of arching, with vertical center line for symmetrical centre, lining shuttering split is set to symmetrical half range template, half range template is made up of arch template 31 and side wall template 32, arch template 31 and side wall template 32 are carried out hinged with meta bolt 33, and at the connecting portion of meta bolt 33, between arch template 31 and side wall template 32, rod-adjurstable 34 is set, rod-adjurstable 34 is arranged in triangle with meta bolt 33, can adjust by regulating the length of rod-adjurstable 34 and actuate degree between arch template 31 and side wall template 32, be connected by regulating block 35 between the arch template 31 of symmetrical half range template, the regulating block 35 changing different in width can adjust the width of lining shuttering.
as Fig. 1shown in, arranging formwork support structure in the present embodiment is: support across being supported between symmetrical half range template using truss 21 as top cross, truss 21 is in falling " ware " font, the wing bar 21a that two ends, truss 21 top are stretched out is supported in the top longitudinal beam 12 of chassis, the end of wing bar 21a is provided with adjustable connecting-rod 21b, adjustable connecting-rod 21b is adjustable length on the bearing of trend along wing bar 21a, and the front end of adjustable connecting-rod 21b is connected on the bottom back of the body rib of the arch template 31 of corresponding side; Carry on the back between rib in the two ends of truss 21 and the stage casing of the side wall template 32 of corresponding side and oblique dowel bar 41 is set; Vertical shore 42 is set between truss 21 and arch template 31, overall " cave " character form structure forming large headroom.
