Abstract
The invention discloses a horizontal drainage device for tunnel palisades. According to the horizontal drainage device for the tunnel palisades, a tunnel rock stratum and a primary lining supporting layer are included. The joint surface of the tunnel rock stratum and the primary lining supporting layer is provided with a water diversion pipe which comprises a pervious pipe wall and a water-proof pipe wall. The pervious pipe wall is arranged to be close to the tunnel rock stratum and located above the water-proof pipe wall. The water diversion pipe is arranged in a prolonged mode along the horizontal cross section of a tunnel arch wall, and pipe openings of the two ends of the water diversion pipe lead to drainage channels on the two sides of a tunnel. When the tunnel is excavated, stratum dripping water located on the joint surface of the tunnel rock stratum and the primary lining supporting layer can pass through the pervious pipe wall, permeates and drops into the water-proof pipe wall and then enters the drainage channels on the two sides of the tunnel under guiding of the water-proof pipe wall for concentrated discharge. The horizontal drainage device for the tunnel palisades is simple is structure, moreover, the phenomenon that a large amount of dropping water is generated when the tunnel is excavated can be effectively avoided, and accordingly the work progress of constructors is ensured.
Description
Technical field
The present invention relates to and relate to field of civil engineering, be specifically related to a kind of tunnel drainage device.
Background technology
In constructing tunnel, need the crag in hole to build the supporting and protection structure with sufficient intensity, i.e. tunnel lining, tunnel lining comprises just lining and two linings, concrete, be that first in hole, on crag, combined bolting and shotcrete (namely squeezing into anchor metal while of sprayed mortar in crag) is to form just lining, when the deflection of first lining structure meets the demands, Reperfu-sion one layer concrete forms two linings.
In lining construction process, in order to ensure the drainage effect in tunnel, between the first lining and two of general needs in tunnel serves as a contrast, drainage system is set, crag infiltration is caused in tunnel drainage passage and concentrates discharge, but when tunnel excavation, due to tunnel surrounding infiltration, drip, especially country rock roof place, a large amount of dripping makes troubles to the ensuing lining construction work of operating personnel.
Summary of the invention
The object of this invention is to provide the transverse drainage of the tunnel crag that a kind of structure is simple, drainage effect is good.
For achieving the above object, the technical solution used in the present invention is: the transverse drainage of a kind of tunnel crag, comprise tunnel rock and just serve as a contrast a sheath, it is characterized in that: the interface place of tunnel rock and just a lining sheath is provided with aqueduct, described aqueduct comprises permeable tube wall and waterproof tube wall, permeable tube wall closes on tunnel rock and arranges and be positioned at the top of waterproof tube wall, and described aqueduct leads to the drainage channel of tunnel two avris respectively along postpone layout and the two ends mouth of pipe of aqueduct of the lateral cross section of tunnel arch wall.
The beneficial effect adopting technique scheme to produce is: when tunnel excavation, dripping and can infiltrate through permeable tube wall and drop down onto waterproof tube wall in the rock stratum being positioned at tunnel rock and the first interface place of a lining sheath, concentrates and discharge in the drainage channel then entering into tunnel two avris under the guiding of waterproof tube wall.Structure of the present invention is simple, and can effectively avoid producing a large amount of dripping phenomenon during tunnel excavation, and then ensures the work progress of constructor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the C-C of Fig. 1 is to sectional view;
Fig. 3 is the structural representation of aqueduct.
Detailed description of the invention
The transverse drainage of a kind of tunnel crag, as illustrated in fig. 1 and 2, comprise tunnel rock A and just serve as a contrast a sheath B, it is characterized in that: the interface place of tunnel rock A and just a lining sheath B is provided with aqueduct 10, described aqueduct 10 comprises permeable tube wall 11 and waterproof tube wall 12, permeable tube wall 11 closes on tunnel rock A and arranges and be positioned at the top of waterproof tube wall 12, and described aqueduct 10 leads to the drainage channel of tunnel two avris respectively along postpone layout and the two ends mouth of pipe of aqueduct 10 of the lateral cross section of tunnel arch wall.During actual installation, can above tunnel tunnel face, the end, boundary that is positioned at tunnel rock A and an in type just lining sheath B arranges aqueduct 10, and then the combined bolting and shotcrete first lining that forms next section prop up sheath B while aqueduct 10 implemented to bury apply fixing.Can infiltrate through permeable tube wall 11 for dripping of tunnel rock A and drop down onto waterproof tube wall 12 like this, in the drainage channel then entering into tunnel two avris under the guiding of waterproof tube wall 12, concentrate discharge.Structure of the present invention is simple, and can effectively avoid producing a large amount of dripping phenomenon during tunnel excavation, and then ensures the work progress of constructor.
Concrete scheme is: as illustrated in fig. 1 and 2, radial section semicircular in shape and the V-arrangement respectively of described permeable tube wall 11 and waterproof tube wall 12, and opening correspondence that is semicircle and V-arrangement is arranged.Select semicircular permeable tube wall 11 to be not only conducive to arranging on non-planar excavation scar, applicability is strong, and convenient spray anchor mortar is buried deposited fixing in all directions.In addition, described waterproof tube wall 12 selects V-shaped groove shape structure, like this when dewatering installation is in place, can bear the impulse force of the spray anchor mortar of high speed and high pressure during combined bolting and shotcrete better, thus ensures the stability in use of dewatering installation.
As further preferred version, as illustrated in fig. 1 and 2, the dual-side of permeable tube wall 11 is along being furnished with first, second relative buckling groove 13,14 of notch continuously respectively, the dual-side of waterproof tube wall 12 is along being furnished with external first, second flange 12a, 12b continuously respectively, and described first, second flange 12a, 12b are fastened in the groove of first, second buckling groove 13,14 respectively.Effectively connected and fixed first, second flange 12a, 12b of waterproof tube wall 12 by first, second buckling groove 13,14 like this, reliability is high.
Further, described permeable tube wall 11 and first, second buckling groove 13,14 are one-body molded by high-density polyethylene plastics; Described waterproof tube wall 12 is bent into by steel.Like this under the momentum effect of spray anchor mortar, waterproof tube wall 12 has certain voltage endurance capability on the one hand, permeable tube wall 11 and first, second buckling groove 13,14 have again certain elastic buffer ability on the other hand, dewatering installation effectively can be avoided like this under both actings in conjunction to be flattened by mortar punching press in fixation procedure, and then ensure the drainage effect of dewatering installation.
Preferably, the outward flange spacing of first, second flange 12a, 12b is greater than and the bottom land spacing of first, second buckling groove 13,14 close.Because permeable tube wall 11 and first, second buckling groove 13,14 are one-body molded by high-density polyethylene plastics, there is certain elasticity, therefore by the elastic deformation of first, second buckling groove 13,14, first, second flange 12a, 12b reliability can be connected in first, second buckling groove 13,14, connective stability is good.
