Abstract
The invention relates to a novel tunnel waterproof structure, which can prevent a waterproof plate from being damaged and the back being voided, and does not influence the thickness of secondary lining concrete. The novel tunnel waterproof structure comprises a sprayed concrete layer and a secondary lining concrete layer; the waterproof plate is arranged between the sprayed concrete layer and the secondary lining concrete layer; and a filler layer is arranged between the waterproof plate and the sprayed concrete layer.
Description
One, technical field:
The present invention relates to a kind of buildings waterproof structure, especially relate to a kind of novel tunnel waterproof construction.
Two, background technology:
In the background technology, the supporting and protection structure in tunnel adopts composite lining usually, and separation layer (splash guard) promptly is set between supporting in the early stage and the secondary lining.From point of theory, this composite lining form of structure can be ended the water resistance in the country rock beyond splash guard effectively, guarantees that tunnel lining is water-tight, does not seep water.Yet, in the work progress, be difficult to guarantee tunnel preliminary bracing section rule, smooth-going at the scene, often because rough surface layer causes splash guard breakage and back generation to be come to nothing.Splash guard will lose water-proof function, and coming to nothing of splash guard back can form natural water space in case appearance is damaged.The immediate cause that these all can become tunnel lining percolating water has a strong impact on workmanship, and operation brings potential safety hazard to the tunnel.
Three, summary of the invention:
The present invention provides a kind of novel tunnel waterproof construction in order to solve the weak point in the above-mentioned background technology, and it can avoid splash guard breakage and back to come to nothing, and does not influence the concrete thickness of secondary lining.
For achieving the above object, the technical solution used in the present invention is:
A kind of novel tunnel waterproof construction comprises shotcrete layer and secondary lining layer of concrete, it is characterized in that: be provided with splash guard between shotcrete layer and secondary lining layer of concrete, be provided with packing layer between splash guard and the shotcrete layer.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
The present invention can not only effectively avoid splash guard to break, and makes splash guard and sprayed mortar closely connected, avoids the splash guard back to come to nothing, and does not influence the concrete thickness of secondary lining, thereby makes that the waterproof effect of composite lining is given full play to.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is construction process figure of the present invention.
Among the figure, 1-shotcrete layer, 2-splash guard, 3-secondary lining layer of concrete, 4-packing layer.
Five, the specific embodiment:
Referring to Fig. 1, the present invention includes shotcrete layer 1 and secondary lining layer of concrete 3, between shotcrete layer 1 and lining concrete layer 3, be provided with splash guard 2, be provided with packing layer 4 between splash guard 2 and the shotcrete layer 1.Referring to Fig. 2, during actual fabrication, pressure injection has the filler of cementing agent effect between the jog of pneumatically placed concrete and splash guard, form packing layer, splash guard can be arranged on the level and smooth preliminary bracing surface, tunnel, then lateral irrigation is annotated lining concrete within it, realizes having the high-durability tunnel water proofing structure of " do not hinder concrete filling, and the water proof structure closely connected with concrete ".Concrete steps are: be width that the splash guard of 1.5m is processed into wide 6.0m(long span earlier) splash guard.Along the periphery of traveling formwork chassis splash guard is launched then, and good in the fixed-site of regulation, between splash guard and sprayed mortar, pour into the filler of backfill then.At last, side form is built the secondary lining concrete outside splash guard.Adopt pressure injection equipment respectively the curing compound that solidifies of force feed and accelerating admixture to the pressure injection place, mix the back on abutment wall top, left tunnel right side, haunch and vault 5 places are provided with the pressure injection pipe, pressure injection successively from bottom to top.
The present invention has following characteristics:
1, improve water proofing property:
1.5m width waterproof plank factory process is become wide 6.0m(long span) move into, reduced the field Welding operation; The setting of packing layer has reduced the outstanding breakage to splash guard of rock bolt head; Study for a second time courses one has flunked simple and convenient after the splash guard breakage.And splash guard and sprayed mortar are closely connected, can really play the effect of waterproof barrier.
2, improve the concrete quality of secondary lining:
Sprayed mortar and secondary lining concrete are fully isolated, and guarantee that the secondary lining concrete is not subjected to that country rock is phreatic to be influenced.And the traveling formwork chassis can strictly be controlled the preliminary bracing profiled outline, guarantees that the secondary lining concrete thickness is even, and meets design requirement.Simultaneously, the packing layer in the secondary lining concrete and the splash guard outside is closely connected, forms overall structure.
3, reduce cost:
The quality of reduction splash guard because not torn and puncture to wait, splash guard influences, even also can satisfy the requirement of waterproof; Position for the sprayed mortar surface irregularity does not need to repair, and has saved the construction operation time.The waterproof requirement that can adapt to simultaneously, different situations (full section, half section etc.).
4, reduce the load of operating environment, surrounding enviroment:
Splash guard can adopt manpower or machinery to lay, and operation intensity is low; In the construction, can recover the groundwater table of tunnel perimeter.
