Technical field
The present invention relates to railway steel bridge panels to protect field, and in particular to a kind of railway steel bridge panel waterproofing protection structure and
Its construction method.
Background technique
In recent years, with the fast development of high-speed railway, the bridge deck structure of pervious " open bridge floors, in length and breadth beam and sleeper "
Since its target velocity is low, road-ability is poor, the demand of railway high speed development is no longer satisfied, correspondingly, railway ballast bridge floor
The selection relatively reasonable as one, and the waterproofing protection in railway ballast bridge floor between railway ballast and steel plate becomes influence bridge durability
Key factor.Since protective layer bears Fatigue Load for a long time in use, it often will appear different degrees of split
The breakoff phenomenons such as seam, broken, protective layer will cause the destruction of waterproof layer, and then influence the durable of railway steel bridge once destroying
Property.Therefore, railroad bridge needs protective layer that can not be crushed, not collapse, not aging under chronic fatigue load action, so as to
It is effectively protected steel bridge main structure.And in existing technology, the waterproof protective layer of rail iron bridge floor is anti-with normal concrete
Based on water conservation layer, the characteristics of normal concrete waterproof protective layer is due to its own material, structure, tensile property and deformation association
Tune ability is poor, in practical application, is relatively also easy to produce crack class disease and moisture is made to invade steel bridge deck, and then corrode Steel Bridge Deck
Plate, can not reach preferable protective effect, and waterproof protective effect is weaker.
In view of this, being badly in need of improving existing rail iron bridge floor waterproof protective layer, it is anti-to enhance its rail iron bridge floor
Water conservation layer makes it play preferable protective action to steel bridge deck.

Specific embodiment
The present invention for existing normal concrete waterproof protective layer to the insufficient problem of rail iron bridge floor protective capacities,
A kind of railway steel bridge panel waterproofing protection structure and its construction method are provided, by providing a kind of cement with very-high performance
Based composites waterproof protective layer structure meets railway steel bridge panel to the needs of waterproof performance, and the present invention can be effectively reduced and be applied
The crack that protective layer generates in work process and actual use, can make protective layer give full play to its water-proof function, protect steel bridge deck,
The present invention is described in detail with specific embodiment with reference to the accompanying drawings of the specification.
As shown in Fig. 1~2, a kind of railway steel bridge panel waterproofing protection structure provided by the invention, including 1 He of steel bridge deck
The gear tiny fragments of stone, coal, etc. wall 2 of 1 two sides of steel bridge deck is set, and the top surface of steel bridge deck 1 is equipped with WELDING STUDS 3 and protective layer.WELDING STUDS 3 is arranged
Between gear tiny fragments of stone, coal, etc. wall 2, protective layer includes the erosion resistant coating 4 set gradually from the bottom to top, waterproof protective layer 5 and top dressing layer 6.
Erosion resistant coating 4 is the common Functional anticorrosive paint layer of steel bridge deck, such as electric arc aluminium spraying dope layer, zinc-rich coating
Dope layer, epoxy zinc rich primer dope layer and epoxy-tar paint layer etc., the dope layer with anti-corrosion function have construction party
Just, the advantages that quality is easily controllable, favorable anti-corrosion effect.
Waterproof protective layer 5 is ultra high performance cementitious waterproof protective layer, by ultrahigh-performance cement-based composite wood
Material is made, and has low-shrinkage.Since concrete material will appear volume-diminished phenomenon in condensation initial stage or hardening process, tool
Body, normal concrete has larger shrinkage, it will lead to concrete material surface after molding there are more contraction fissure,
The gap will have a direct impact on the protective performance of protective layer.The ultra high performance cementitious that the present invention uses its shrinkage is very
It is low, it can effectively reduce the contraction fissure of condensation or hardening process generation.
In the present invention, waterproof protective layer 5 has the characteristics that non-evaporating feeding.In the art, steam curing is carried out to concrete
During, due to being influenced by factors such as environment and field conditions, easily causes concrete structure uneven heating even, cause coagulation
Native surface generates steam-cured crack.Steam curing is not necessarily in the ultra high performance cementitious work progress that the present invention uses,
Condensation hardening process can be sufficiently completed at normal temperature, can effectively avoid generating crack during steam maintenance.
In the present invention, to improve intensity, a certain amount of steel fibre is mixed in waterproof protective layer 5.Due to normal concrete
Material property is insufficient, and under action of traffic loading, normal concrete waterproofing protection layer surface can generate a large amount of structural cracks.This
In invention, due to being mixed with steel fibre in 5 layers of waterproof protective layer, it can effectively inhibit the structural of 5 surface of waterproof protective layer
Crack.
In the present invention, steel mesh 7 in length and breadth are laid in waterproof protective layer 5, steel mesh 7 is set as single layer in length and breadth, and steel in length and breadth
Muscle net 7 include respectively along longitudinal direction with the reinforcing bar laterally arranged, the preferably reinforcing bar of steel mesh 7 longitudinally, laterally arranged in length and breadth
Spacing is 20~200mm.
In the present invention, waterproof protective layer 5 with a thickness of 20~80mm.
Top dressing layer 6 is formed by surface spread water-repellent paint.Top dressing layer 6 includes polymer modified asphalt waterproof
Dope layer, polyurethane water-proof paint layer and polymer cement waterproof paint layer.
The invention has the following advantages that
(1) waterproof protective layer 5 uses ultra high performance cementitious, and low-shrinkage can effectively reduce waterproof guarantor
The contraction fissure of sheath 5；
(2) waterproof protective layer 5 formed by ultra high performance cementitious has non-evaporating feeding characteristic, can be effective
Reduce the steam-cured crack generated in work progress；
(3) steel fibre mixed into ultra high performance cementitious can restrained effectively waterproof protective layer 5 and exist
Structural crack under load action.
To sum up, the waterproof protective layer 5 in the present invention, can play better waterproof effect.
The present invention also provides to making a kind of above-mentioned construction method of railway steel bridge panel waterproofing protection structure, including it is following
Step:
S1, two gear Zha Qiang are arranged in the two sides of steel bridge deck；
