Along with the development of China's reform and opening-up, economic prosperity, urbanization process are accelerated, the tunnel construction such as municipal highway, subway, plumbing, power cable, air feed is rapid.The construction of subterranean tunnel alleviates the problem of shortage of land resource, improves ground environment and traffic, but underground construction inevitably also exists structural leakage water problems, affects normal operation and the application life in tunnel.Therefore engineering waterproofing design and construction is the important component part that underground tunnel project is implemented.
The top board of shallow earthing underground structure, by being also subject to that temperature becomes while influence on groundwater, the effect of drying and watering cycle and ground level road impact load.If waterproof measure is improper in this case, the durability of structure will be had a strong impact on; And the waterproofing materials on top board does not almost have recoverability, therefore extremely important to the research of the reliability of waterproofing materials.
Investigation shows, zero earthing waterproof roofing difficult point is mainly: (1) tunnel roof is close to zero earthing, owing to lacking the heat insulation of top earthing and cushioning effect, obvious with four seasons temperature Change outside top board, internal-external temperature difference is large, the larger thermal stresses of easy generation, (2) top board directly bears traffic above-ground load (comprising the impact load that vehicle rolls and brakes).These effects make concrete self easily produce crack, affect the self waterproofing system of structure, reduce the application life of structure.
These unfavorable factors in zero earthing top board self waterproofing also have an impact to top board outer waterproofing layer: (1) waterproofing course internal-external temperature difference is large, make waterproofing materials self produce tension stress, require high to the hot strength of material and expansion and contraction.(2) waterproofing materials directly bears the impact load that vehicle rolls and brakes, requirements at the higher level are proposed to material self-strength, impact property and abrasion resistance, the reliability that waterproofing materials and top board bond to be ensured simultaneously, flake even depart from structure in order to avoid draw waterproofing materials, cause waterproofing course to lose efficacy.
Usual underground construction has more than 2m earthing, and its waterproof type have accumulated certain experience after experienced by many project practice.But when underground construction becomes shallow earthing or zero earthing, just create series of problems, occurred bridge waterproof and the joint descending structurally waterproof traditionally, that a kind of conventional waterproof mode is all difficult to completely well adapt to this pattern.
Rubber powder levigate for junked tire is applied to flexible pavement, has the history of decades.In order to promote a conservation culture, protection of the environment and natural resource, the importance that over nearly 10 years, scrap rubber utilizes is once more by understanding and concern.Especially the most general as Old cement concrete transformation asphalt overlay.In order to prevent reflection crack, application of rubber pitch arranges stress absorbing layer and have received good effect, especially progressively defines the basic model that rigid pavement " changes black " to transform in vain.Rubber asphalt stress absorbing layer refers to and is sprayed on road surface by rubberized asphalt binder, and gathering materials of spreading single particle size is covered subsequently, becomes binder film through rolling.Different according to spreading pellet particle size, its thickness changes within the scope of 9 ~ 12mm.Asphaltic road-mix surface course is overlayed on this layer, then this one deck of rubber asphalt film becomes stress absorption interlayer (Stress-absorbing Membrane Interlayer, be called for short SAMI), upload stress because it has absorption sub-layer and make it the function of dissipation, also there is the ability preventing rainwater infiltration simultaneously, therefore there is the effect of waterproofing course.But the data of there is no shows, rubber asphalt stressor layers is applied to road tunnel waterproof roofing paving structure.
Summary of the invention
The object of the present invention is to provide and a kind of there is road tunnel waterproof roofing pave-load layer composite construction under zero earthing of excellent water resistance and opposing impact load ability.
To achieve these goals; technical scheme of the present invention is as follows: a kind of zero earthing lower roof plate waterproof pave-load layer composite construction, is characterized in that this structure is followed successively by rubber asphalt topping, waterproofing course, epoxy resin scratch coat, cement concrete top board from top to bottom.
Cement concrete top board arranges draining horizontal wall inscription, and the gradient is preferably 0.5% ~ 1%, strengthens from drain function.
Epoxy resin scratch coat adopts epoxy adhesive brushing one deck or two-layer, epoxy adhesive consumption 0.5 ~ 1kg/m
2, at epoxy adhesive surface spreading quartz sand.
Waterproofing course adopts heat molten type waterproof roll, and thickness is not less than 4mm.
Rubber asphalt topping adopts rubberized asphalt binder and single particle size to gather materials, through rolling the binder film of formation.
Waterproof have employed three-layer protection system: epoxy resin scratch coat+waterproofing course+rubber asphalt topping.Epoxy resin can effectively be gone down to the grass-roots units surface, can not only closed concrete top board, prevent moisture in concrete from rising to substrate surface, also play the waterproof action making up waterproofing course simultaneously, guarantee the bonding of concrete roof and waterproofing course.Waterproofing course adopts modified asphalt hot-melt type waterproof roll, has good adhesive property with rubber asphalt transition zone.Rubber asphalt transition zone refers to and adopts rubberized asphalt binder and single particle size to gather materials, through rolling the binder film of formation; Rubber asphalt transition zone is arranged between waterproofing course and asphalt mixture surfacing, both the effect of tack coat and waterproofing course can have been played, also can be used as stress absorbing layer: the reflection crack that control concrete roof causes due to drying shrinkage or temperature contracting develops to asphalt mixture surfacing simultaneously, waterproof failure after effectively preventing the waterproofing course caused because of roof break from tearing, plays waterproofing course effect again.
Based on above-mentioned theory, a kind of waterproof roofing pave-load layer composite construction of the present invention, is followed successively by rubber asphalt topping, waterproofing course, epoxy resin scratch coat, cement concrete top board from top to bottom.Accordingly, reach the water resistance of underground structure under raising zero earthing, extend the application life of road tunnel.The road tunnel waterproof roofing pave-load layer composite construction of the present invention's design has good waterproof effect; three layers of water-proof system (epoxy resin scratch coat+waterproofing course+rubber asphalt topping) the comprehensive waterproof effect arranged can not only ensure that waterproofing materials and top board bonds, can reduce the waterproofing course inefficacy that the crack due to concrete roof generation causes simultaneously.Rubber asphalt topping slow down the impact of vehicular impact load on waterproofing course, avoids waterproofing course and top board structure peels off the waterproof failure caused.The present invention is a kind of effective waterproof roofing pave-load layer composite construction effectively resisting drying and watering cycle and ground level road impact load.This waterproof roofing pave-load layer composite construction has the ability of excellent water resistance and opposing impact load, greatly improves the integrity and effectiveness of road tunnel water-proof system, enhances structure durability, can meet the requirement of road tunnel waterproof roofing.
