Description
Technical field
The utility model visits device before relating to a kind of tunnel piercing, is specifically related to a kind of energy-saving tunnel and Double pilot tunnel.
Background technology
In tunnel excavating process, because different landform also exists different harm, just imperative for visiting technology before tunnel, it effectively can not only ensure the Reasonable adjustment to whole mining process, the supporting of giving vent to anger can be carried out, for follow-up excavation provides condition more easily simultaneously.Existing pilot tunnel form mostly is simple supporting and protection structure, but is difficult to carry out good front-probe support in some rich water packsand areas.
Utility model content
The purpose of this utility model is for above-mentioned Problems existing and deficiency, provides the energy-saving tunnel and Double pilot tunnel of a kind of reasonable in design, stable mechanical property.
For achieving the above object, the technical scheme taked is:
A kind of energy-saving tunnel and Double pilot tunnel, comprise the left pilot tunnel and right pilot tunnel that lay respectively at the multiple-arch tunnel left and right sides, reinforced mesh, the Steel bar rack be pressed together on reinforced mesh, the stiffness steel plate being arranged on anchor pole end and the uniform cross bar be arranged on bottom Steel bar rack that described left pilot tunnel and right pilot tunnel include anchor pole, fit with tunnel top, described Steel bar rack is provided with a series of conduit along direction, tunnel, described cross bar two bottom sides is provided with rhone, is provided with prestressed draw-bar between described cross bar and Steel bar rack.
Described prestressed draw-bar comprises the adjusting nut of two pull bars being arranged on two ends, the dextrorotation screw thread being separately positioned on end corresponding to two pull bars and derotation screw thread and coupling setting.
Adopt technique scheme, acquired beneficial effect is:
The utility model reasonable in design, stable mechanical property, be applicable to rich water packsand area, draining can be carried out timely, ensure that the degree of deformation of whole supporting is little simultaneously, improve the stability of supporting, guarantee that construction safety is convenient, front-probe support of the present utility model is that follow-up digging provides good operating environment, the effective stability ensureing whole construction speed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Sequence number in figure: 1 be left pilot tunnel, 2 be right pilot tunnel, 3 be anchor pole, 4 be reinforced mesh, 5 be Steel bar rack, 6 be stiffness steel plate, 7 be cross bar, 8 be conduit, 9 be rhone, 10 be pull bar, 11 for adjusting nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
See Fig. 1, a kind of energy-saving tunnel and Double pilot tunnel, comprise the left pilot tunnel 1 and right pilot tunnel 2 that lay respectively at the multiple-arch tunnel left and right sides, described left pilot tunnel 1 and right pilot tunnel 2 include anchor pole 3, the reinforced mesh 4 of fitting with tunnel top, be pressed together on the Steel bar rack 5 on reinforced mesh 4, be arranged on the stiffness steel plate 6 of anchor pole 3 end and the uniform cross bar 7 be arranged on bottom Steel bar rack 5, described Steel bar rack 5 is provided with a series of conduit 8 along direction, tunnel, described cross bar 7 two bottom sides is provided with rhone 9, prestressed draw-bar is provided with between described cross bar 7 and Steel bar rack 5, described prestressed draw-bar comprises two pull bars 10 being arranged on two ends, be separately positioned on dextrorotation screw thread and the derotation screw thread of the end of two pull bar 10 correspondences, and the adjusting nut 11 that coupling is arranged.
The utility model reasonable in design, stable mechanical property, be applicable to rich water packsand area, draining can be carried out timely, ensure that the degree of deformation of whole supporting is little simultaneously, improve the stability of supporting, guarantee that construction safety is convenient, front-probe support of the present utility model is that follow-up digging provides good operating environment, the effective stability ensureing whole construction speed.
