Background technology
For rich water Karst Tunnel or submerged tunnel, tunnel lining structure often needs to consider the effect of external water pressure.But current tunnel hydraulic pressure resistance structure is often defined as by " preliminary bracing+secondary lining " and forms, but there is many technological deficiencies in this single Anti-hydraulic Pressure Lining Structure pattern in fact:
1) only consider the effect of preliminary bracing and secondary lining, ignored the supporting capacity of country rock self, particularly implement the mechanics contribution of the country rock after grouting for water blocking.
2) do not consider the impact of tunnel trunk waterproof and water drainage system on tunnel external water pressure, particularly, by adjusting the setting of barrel waterproof and water drainage system, can increase underground water discharge ability, and then reach the effect that reduces external water pressure.
3) simply merely by thickening lining cutting, improve concrete grade etc. and improve hydraulic pressure resistance structural strength, thereby strengthened to a certain extent the gap of liner structure and country rock mechanical property, make country rock share the effect of external water pressure fainter.
Visible, current this single hydraulic pressure resistance structural shape, outside under effect of water pressure, the degree of safety of liner structure and durability are difficult to ensure, easily cause lining cutting cracking, lose efficacy, and affect constructing tunnel, operation security, meanwhile, the loss of underground water causes serious environmental problem.
For above-mentioned deficiency, the applicant has invented a kind of tunnel recombination hydraulic pressure resistance structure, to address the above problem.
Utility model content
In view of this, the utility model provides a kind of tunnel recombination hydraulic pressure resistance structure, this tunnel recombination hydraulic pressure resistance structure has been abandoned the irrational tunnel hydraulic pressure resistance structural shape being made up of " preliminary bracing+secondary lining ", consider the many kinds of measures such as reinforce adjoining rock, water blockoff, waterproof and draining, can improve better the hydraulic pressure resistance ability in tunnel, and the safety of liner structure and durability, guarantee construction and the operation security in tunnel.
The utility model addresses the above problem by following technological means:
Tunnel recombination hydraulic pressure resistance structure of the present utility model, it is mainly made up of water reinforcement circle, preliminary bracing, the anti-drainage network system of barrel and secondary lining four parts, the anti-drainage network system of described barrel comprises the splash guard and the secondary lining ring direction drainpipe behind that are arranged between preliminary bracing and secondary lining, and described water reinforcement circle, preliminary bracing, the anti-drainage network system of barrel and secondary lining set gradually from outside to inside.
Further, the anti-drainage network system of described barrel also comprises the longitudinal drainage pipe being arranged between preliminary bracing and secondary lining.
Further, also comprise hole inner water drainage system, described hole inner water drainage system comprises along barrel length direction and is arranged in hole the side gutter under road surface and is horizontally set at the transverse drain that in hole, under road surface and two ends are communicated with side gutter and longitudinal drainage pipe respectively.
Further, also comprise casing, described casing and water reinforcement circle fit tightly.
Further, the section of described water reinforcement circle and secondary lining is annular enclosed shell structure.
Further, described water reinforcement circle comprises a water-blocking layer, and it carries out water reinforcement by the slip casting that is mixed with waterproofing materials to described country rock, and by regulating the mechanics parameter of grouting parameter control country rock.
Further, described water-blocking layer has elasticity.
Tunnel recombination hydraulic pressure resistance structure of the present utility model has following beneficial effect:
1) give full play to water reinforcement circle can be shared external water pressure as bearing structure effect to country rock, changed the problem that in the past merely improves hydraulic pressure resistance structural strength by modes such as thickening lining cutting, raising concrete grades;
2) promoted the compatibility of deformation under effect of water pressure outside of liner structure and country rock;
3) enriched the engineering measure that improves tunnel hydraulic pressure resistance ability;
4) safety and the durability in tunnel have been improved.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the section structure schematic diagram of tunnel recombination hydraulic pressure resistance structure of the present utility model;
Fig. 2 is Tu1Zhong A district enlarged diagram;
Fig. 3 is the structural representation of water reinforcement circle in tunnel recombination hydraulic pressure resistance structure of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Fig. 1 to 2: the tunnel recombination hydraulic pressure resistance structure of the present embodiment, it is mainly made up of water reinforcement circle 2, preliminary bracing 3, the anti-drainage network system of barrel and secondary lining 4 four parts, the anti-drainage network system of described barrel comprises the splash guard and the secondary lining ring direction drainpipe 5 behind that are arranged between preliminary bracing 3 and secondary lining 4, and described water reinforcement circle 2, preliminary bracing 3, the anti-drainage network system of barrel and secondary lining 4 set gradually from outside to inside; Preferably, also comprise casing 1, described casing 1 fits tightly with water reinforcement circle 2.On the existing basis of supporting in the early stage and secondary lining, increase the anti-drainage network system of water reinforcement circle and barrel, give full play to country rock can be shared external water pressure effect as bearing structure, promoted the compatibility of deformation under effect of water pressure outside of liner structure and country rock; In addition, water reinforcement circle and preliminary bracing also have sealing underground water, control the effect of water seepage of tunnel amount and guarantee construction period cavern's stability.Tunnel recombination hydraulic pressure resistance structure of the present utility model has been enriched the engineering measure of tunnel hydraulic pressure resistance ability, has improved safety and the durability in tunnel.
As the further improvement of technique scheme, the anti-drainage network system of described barrel also comprises the longitudinal drainage pipe 7 being arranged between preliminary bracing 3 and secondary lining 4.Described longitudinal drainage pipe 7 can be interconnected multiple ring direction drainpipes 5, so that the discharge pressure of ring direction drainpipe 5 is uniformly distributed.
