Abstract
The present invention relates to a supporting and protecting structure for an underground laneway in hanging and assembling way. the supporting and protecting structure is characterized in that a plurality of supporting and protecting plates are assembled into a supporting and protecting layer; each supporting and protecting plate is hung over the wall rock by a roof bolt; a flexible gap is kept between two adjacent plates; the width of the flexible gap is determined by the size of the laneway; the bigger the laneway deforms, the wider the flexible gap is; a flexible sealing strip is pressed into the flexible gap; the present invention has the beneficial effects that every supporting and protecting plate is hung by the roof bolt, which takes fully advantages of the supporting and protecting of the roof bolt that the wall rock is fixed together by the roof bolt and the supporting and protecting plates are hung over the wall rock by the roof bolt, thereby playing in a hanging role; the plate structure is constructed easier than the one-whole structure; the flexible gap is kept between two adjacent plates, and during the deforming of the wall rock, the gaps between the plates are contracted to release a part of the ground pressure, which changes the rigid supporting and protecting into the flexible supporting and protecting, thereby conforming to the modern flexible supporting and protecting principle; due to the release of the ground pressure, the supporting and protecting pressure is reduced, thereby avoiding the damage of the supporting and protecting layer.
Description
Technical field
The present invention relates to the support of underground tunnel material.
Background technology
At present, the form of support of underground tunnel is varied, builds arch, gunite, bolt support, anchor net gunite or the like as concrete.The common feature of these support patterns is that a sheath is a complete hard integral body, so be called the rigidity supporting.When underworkings was out of shape, powerful subsurface pressure can damage rigidity supporting pressure break.Therefore present solution is, strengthens supporting thickness or lays reinforcing bar, with the opposing subsurface pressure.Will strengthen the drift section size like this, the waste support material increases construction volume.
Summary of the invention
The objective of the invention is to solve the deficiency of present underground passage rigidity supporting, a kind of hanging-up assembling supporting construction that can have certain amount of contraction is provided.
For achieving the above object, of the present inventionly take following technical scheme: it is to be assembled into a sheath by some supporting plates, every supporting plate is hung on roadway surrounding rock with anchor pole, leave the shrinkage joint between two adjacent plates, the width at shrinkage joint is decided on the roadway deformation size, be out of shape greatly more, the shrinkage joint is wide more.When trickle being arranged, be pressed into elastic sealing strip in the shrinkage joint as country rock.
Above-mentioned supporting plate can be used the reinforced concrete structure plate, also can have the engineering plastics plate of ribs.
The periphery of plate can adopt plane, and the shrinkage joint of this moment is a butt joint.
The periphery of plate also can adopt step-like, and the shrinkage joint of this moment is overlapping the slot.
The application's good effect is:
1, every supporting plate is hung by anchor pole, has promptly utilized the advantage of bolt support that country rock is anchored at together, has utilized anchor pole that the supporting plate is hung on country rock again, has played the effect of hanging.
2, this plate structure is constructed than overall structure conveniently.
3, be reserved with the shrinkage joint between the plate, when surrouding rock deformation, shrink between the plate, press on release portion ground, makes the rigidity supporting become flexible support, meets the principle of modern flexible supporting.Obtain discharging because press on ground, supporting pressure is reduced, avoided the breakoff phenomenon of a sheath.

The specific embodiment
As shown in Figure 1, hanging-up assembling supporting construction of the present invention is assembled into a sheath by 12 supporting plates 1, every supporting plate 1 usefulness anchor pole 2 is hung on roadway surrounding rock 3, leave shrinkage joint 4 between two adjacent supporting plates 1, the width at shrinkage joint 4 is decided on the roadway deformation size, is pressed with elastic waterstop bar 5 in the shrinkage joint 4.
Fig. 2, Fig. 3, reinforced concrete plate 6 shown in Figure 4 are rectangle contour bodies, its cambered surface should adapt with the section configuration in tunnel, have three anchor holes 7 to be used for anchor pole lifting on its longitudinal axis, its peripheral end face is a step end face 8, be used for adjacent between overlap joint; Its internal placement has distributing bar 9, to gain in strength.Its size is moved with suitable manpower and is installed as suitablely, is generally 400 * (600-800) mm and is advisable, and three boltholes decide on the country rock situation, can be with a middle anchor hole lifting during adjoining rock stability, and unstable two anchor holes with both sides of country rock lift.
Fig. 5, Fig. 6, engineering plastics plate 10 shown in Figure 7 are formed by the materials processing of engineering plastics plastic-steel class.It is a rectangular contour body, and its cambered surface should adapt with the section configuration in tunnel, has three anchor holes 11 to be used for the anchor pole lifting on its longitudinal axis, ribs 13 is arranged to gain in strength in its periphery and the cambered surface, and its peripheral end face is a planar end surface 12.Three anchor holes are decided on the country rock situation, can lift unstable two the anchor hole liftings with both sides of country rock during adjoining rock stability with a middle anchor hole.
