The beneficial effects of the utility model are:
Adopt open needle beam, cancelled the scissor stabilizing member of existing equipment needle beam inside, form with needle beam walking wheel carrier overlap joint respectively by the walking track, rectangle frame beam with a kind of more heavy in section modulus substitutes, strengthened the locus of needle beam inside casing simultaneously, finish the displacement work of needle beam and template with sliding type, reserve certain working space for current construction bridge simultaneously; And further strengthen its stability with needle beam stopping means and needle beam movable transverse pull bar.
Adopt trestle in the needle beam, be connected with front and back end trestle support system by the mode of being spirally connected, can satisfy the current and carrying condition of construction, when crossing car, support system makes it separate with open needle beam trestle lifting in the needle beam, when open needle beam is shifted, support system resets, and makes trestle and open needle beam overlap joint in the needle beam, and moves with open needle beam; Adopt the rear end trestle, when satisfying the current condition of construction, also in type concrete has been played protective effect.
The utility model can satisfy tunnel excavation simultaneously, slag tap current and concrete lining cutting requirement, the rail line mode of rear end trestle, and the special displacement mode of open needle beam and template, can better alleviate molded mixed earth before intensity does not reach designing requirement fully, because cross the current load impact of car to mixing the damage of earth face; The separate type stripping means of backform, side form and bed die more is well positioned to meet the convenience requirement of using in the work progress, and current enough space and the needs that provide of constructing are provided.
The utility model can shorten the construction period in existing tunnel greatly, and certain economic benefits and social benefit are arranged.
