Embodiment
The utility model is described in detail with reference to embodiment.
The utility model is directed to the serious paragraph of water seepage of tunnel disease, in the case where not increasing scored position, makes full use of Spilled water hole is set up in existing cutting, using the flexible porous tube drainings of φ 50, optimizes cutting scheme.By being performed on the outside of tunnel double-lining One layer of steel bushing arch functional layer steel plate adds other auxiliary functional layers such as rubber slab, carries out Thickness of Entirety Stabilization and is no more than 4cm, to tunnel Fouling of clearance gauge is avoided while overall structure is reinforced.
Infiltration disposal system is reinforced in a kind of tunnel-liner that the utility model is related to, at the existing cutting 7 of tunnel-liner 2 The inverted trapezoidal groove of ring is chiseled, interval sets the spilled water hole 1 of radial direction into country rock 3 in inverted trapezoidal groove, set in spilled water hole 1 Flexible porous tube 8, sets the flexible porous tube 8 of ring in inverted trapezoidal groove, the flexible porous tube 8 of ring and radial direction it is flexible porous Pipe 8 is connected by threeway 9.In the cable trough gutter of the bottom incoming tunnel of flexible porous tube 8 of ring.
Poured in the inverted trapezoidal groove of tunnel-liner 2 on the flexible porous tube 8 of ring and be inoculated with epoxy resin mortar 6, the surface of epoxy resin mortar 6 is filled out Filled with cement-base infiltration crystallization loss circulation material 5.Cement-base infiltration crystallization loss circulation material 5 is concordant with lining cutting 2, and surface is coated with high-elastic Thick matter water-proof acrylic acid paint 4.Closed by tightening the colligation of steel wire 11 termination of flexible porous tube 8 of radial direction.Flexible porous tube 8 with The junction of threeway 9 is enclosed with non-woven fabrics 10.
In the cable trough gutter of the bottom incoming tunnel of flexible porous tube 8 of ring, insulation material is provided with above termination 12。
The construction joint of ring, construction joint external coating water-proof bond material 17 are formd after the closing of inverted trapezoidal groove, and is laid Steel plate set arch 16 is covered on butyl rubber plate 15, butyl rubber plate 15, is fixed, is set at chemical anchor bolts 13 by chemical anchor bolts 13 There is anchor adhesive 14 as sealing.Consolidated at steel plate set 16 arch springings of arch by billet 21 and High-strength anchor bolt 22 with tunnel original structure It is fixed, secondary casting concrete formation bow member concrete anchor block 20 on arch springing.
Specific construction step is as follows:
First, cutting water draw-off
It is more in view of early stage tunnel scored position, in the case where not increasing scored position, make full use of existing cutting 7 Spilled water hole 1 is set up, optimizes cutting scheme, using the draining of 50 flexible porous tubes of φ 8.As shown in Figure 1.
1. the original coating of tunnel-liner is cleaned out(Lining concrete is exposed), remove existing ceramic tile, it is ensured that entirely treat Punishment two serves as a contrast dry tack free cleaning, without leak, no-sundries etc.;
2. the existing position packing material of cutting 7 is removed, is cleaned out;Existing cutting is digged, in inverted trapezoidal, bottom width 8cm, top Wide 15cm, cutting inwall needs clear water to clean out, it is impossible to there is dust, increases packing material bond effect, as shown in Figure 2;
3. cutting is dug to design position, is set in bottom.Φ 80 drills, hole depth 2.5m, empties, and embedding φ 50 is soft Water-permeable pipe 8, Loess Layer should not pore-forming location water-permeable pipe can be filled in using the reinforcing bar mode of bringing into, permeable pipe end answers colligation to seal Close, prevent that silt from entering water-permeable pipe, influence permeable effect;
4. ring water-permeable pipe is connected with radial direction water-permeable pipe using professional three-way pipe, it is ensured that draining water flowing effect, such as Fig. 3 institutes Show.
5. after radial direction water-permeable pipe, ring water-permeable pipe are installed, permeable pipe surface is closed using epoxy resin mortar 6, filled Cement-base infiltration crystallization loss circulation material 5 blocks cutting, the high-elastic thick matter water-proof acrylic acid paint 4 of external coating;
6. cable trough gutter is deepened in the permeable bottom of the tube access of ring, and the tunnel illumination electricity consumption is introduced directly into hole from arch It is interior, cable trough is not walked, cable groove location can be made full use of to set up insulation draining ditch water discharge;
7. tunnel entrance increases cable trough heat preservation ditch buried depth, prevents that ditch from freezing.
2nd, steel bushing arch closure disposal plant
After two linings be surface-treateds, wait to punish on two lining surfaces in the range of one layer of water-proof bond material of uniform brushing 17, epoxide-resin glue can be used, brushing thickness is about 1-2mm, brushing number of plies 1-2 times, with specific reference to the selection of material construction technology It is required that carrying out, spray range of water-proof bond material can be determined according to follow-up rubber slab scope;Water-proof binding is tackled after brushing Layer carries out quality testing, should be uniform without leakage brush, thickness, no sag etc..
After water-proof bond material 17 is sprayed, thick 15 1 layers of the butyl rubber plates of 2cm are laid on request, or conventional EVA prevents Since water plate, arrange overhauling guidance tape, and overall ring laying, the laying of butyl rubber plate 15 should cover applying in punishment paragraph Work is stitched(Ring is stitched);
Rubber slab is performed finish after can carry out steel plate set arch 16 installation.Steel plate set 16 thickness of arch are 5mm, steel plate set Fixed between arch 16 and tunnel-liner using chemical anchor bolts 13(As shown in Figure 6), the rubber slab punching of crab-bolt bearing, hole week Enclose and sealed with rubber blanket and fluid sealant or water-repellent paint application, it is ensured that its seal.Steel plate assembled rigid unit size can be according to construction Actual conditions are carried out, can be with burst in being assembled outside hole, and sharding unit can be width 80cm, long 2.5 to 3 meters, specifically with convenient Construction is advisable;Steel plate splicing can be spliced using edge-to-edge's form(As shown in Figure 7);
Steel plate set 16 arch springings of arch are welded using pre-buried billet 21, and steel adjustment backing plate is used with original structure ground level High-strength anchor bolt 22 is connected;Billet 21 is thick using the wide 2cm of 15cm, and billet 21 uses the high-strength anchorings of φ 20 with maintenance guidance tape Bolt 22 is connected.After overall steel sleeve-board arch is installed, arch springing should be carried out to secondary casting concrete, bow member concrete is formed and consolidate Determine pier 20(As shown in Figure 8);Performing for anchor block is selected according to site examining and repairing guidance tape actual conditions;
5. after steel plate set arch is performed and finished, surface anticorrosion coating should be carried out(Tunnel decoration color)Implement, in addition should according to will Installation is asked to reset related pipeline and light fixture.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model Cover.
