Abstract
The utility model provides a kind of tunnel double-lining surface seep water cure structure, and along at seam at the construction joint of secondary lining or infiltration crack, the structure includes：U-type groove, waterproof layer, heat-insulation layer and epoxy anticracking grout layer, wherein, YAS semicanals are laid in U-type groove, and the concrete layer of secondary lining is fixed on by hydro-expansive rubber bar and rivet.The utility model provides the lining surface seep water cure construction of one kind two to have runed for many years and being in the tunnel of water enrichment area, plays ponding after exclusion lining cutting, prevents the water leaked out from flowing on runway, influence traffic safety, while improving the effect of tunnel durability.
Description
Technical field
The utility model is related to Tunnel Engineering technical field, specifically provides a kind of tunnel double-lining surface seep water cure knot
Structure.
Background technology
The anti-of domestic new highway tunnel, water discharge technology there has been set of designing technique specification and construction technique normalizing.
Because early stage construction construction technology of tunnel waterproof is limited, a large amount of water seepage of tunnel, the construction disaster of leak are occurred in that.
Newly built tunnels both make to use present guarded drainage technology, due to the limiting of execution conditions, complicated geological structure
And splash guard hang during construction technology defect, cause newly built tunnels after building up soon also easily occur infiltration, leakage
The situation of water.
Therefore, water seepage of tunnel, leak how are prevented, the reparation punishment after infiltration, leak has become Current Highway maintenance
One technical barrier of work.
Utility model content
Technical problem to be solved in the utility model is to provide the lining of one kind two surface for the tunnel in water enrichment area to ooze
Leak treatment structures, play ponding after exclusion lining cutting, prevent the water leaked out from flowing on runway, influence traffic safety, simultaneously
Improve the effect of tunnel durability.
A kind of tunnel double-lining surface seep water cure structure, along seam at the construction joint of secondary lining 1 or infiltration crack 2
Place, the structure includes：U-type groove 3, waterproof layer 7, heat-insulation layer 8 and epoxy anticracking grout layer 9, wherein, YAS semicanals 4 are laid in U
In type groove 3, the concrete layer of secondary lining 1 is sealingly fastened in by hydro-expansive rubber bar 5 and rivet 6.
It is preferred that, the depth of the U-type groove 3 is not less than 15cm.
It is preferred that, the YAS semicanals 4 are arranged on by way of back-off in U-type groove 3.
It is preferred that, the waterproof layer 7 is leak stopping oxidant layer, and thickness is 7cm.
It is preferred that, the insulation layer thickness is 5cm.
It is preferred that, epoxy anticracking grout layer 9 is repair layer, and thickness is 3cm.
Set this construction can in the tunnel runed for many years and be in water enrichment area for being not provided with seepage water cure construction
Ponding after lining cutting is effectively excluded, the traffic safety in tunnel durability and tunnel is improved.
Brief description of the drawings
Fig. 1 is the schematic diagram for the tunnel double-lining surface seep water cure structure that the utility model is provided.
Component, toponym and corresponding mark are shown in figure：
It is secondary lining 1, construction joint or infiltration crack 2, U-type groove 3, Yas semicanals 4, hydro-expansive rubber bar 5, rivet 6, anti-
Water layer (sealing agent) 7, heat-insulation layer 8, epoxy anticracking grout layer 9.
Embodiment
The utility model is further illustrated with example below in conjunction with the accompanying drawings.
Reference picture 1, tunnel double-lining surface seep water cure structure of the present utility model, including：In the construction of secondary lining 1
U-type groove 3 is opened at seam or permeable joints 2, YAS semicanals 4, hydro-expansive rubber bar 5, rivet 6, waterproof layer (sealing agent) 7, insulation are installed
Layer 8, epoxy anticracking grout layer 9.YAS semicanals and hydro-expansive rubber bar 5 between rivet 6 and secondary lining concrete by reliably connecting
Connect.
YAS semicanals 4 are arranged on by way of back-off in U-type groove 3.The depth of U-type groove 3 is not less than 15cm.Waterproof layer 7 is
Leak stopping oxidant layer, thickness is 7cm.Insulation layer thickness is 5cm.Epoxy anticracking grout layer 9 is repair layer, and thickness is 3cm.
During construction, first, the particular location of construction joint or permeable joints is determined, then edge is stitched each 7.5cm unwrapping wire in both sides, cut
Cut, slot, bottom land, which is tried one's best, ensures smooth；Second step, rises drills in groove, and drilling depth is not less than lining thickness；3rd
Step, YAS semicanals are installed along groove center line, and hydro-expansive rubber bar and rivet are installed while installing semicanal；4th step, live mixing
Sealing agent, blocks U-type groove 7cm depths with sealing agent, then installs 5cm heat-insulation layers, finally repairs U-shaped using epoxy anticracking grout
Groove, repairs thickness 3cm.
Engineering practice shows, is installed on the secondary lining surface of seepage aqua region after this drain structure effectively can exclude lining cutting
Ponding, prevents ponding from flowing to road surface, has ensured the traffic safety of road traffic and the durability of tunnel concrete.
Example of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model be not limited to it is above-mentioned
Example, can also be before the utility model objective not be departed from the knowledge that those of ordinary skill in the art possess
The various change made is put, protection domain of the present utility model is also should be regarded as.
