Background
Bridge deck pavement refers to protective layers paved on bridge decks to prevent wheels (or tracks) from directly wearing the bridge decks, spread wheel loads, and provide a smooth and anti-skid driving surface for vehicles.
General cement bridge floor can make the road surface have the change of volume owing to the shrinkage that rises with heat, volume expansion in hot, if bridge floor area is too big can be because the volume expansion of oneself and rise, the road surface undulates, volume contraction in cold can produce and drag, and produce the crack, so will separate one section distance and set up an expansion joint, but the expansion joint of the reservation of traditional bridge deck pavement structure is because natural rainwater infiltration effect, the rainwater leads to the fact the corruption to bridge deck pavement structure inside along the expansion joint easily, thereby make the bridge floor chap, the durability is relatively poor.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is to solve the shortcoming that exists among the prior art, if: the expansion joint of the reservation of traditional bridge deck pavement structure is because natural rainwater infiltration effect, and the rainwater causes the corruption to bridge deck pavement structure inside along the expansion joint easily to make the bridge deck chap, the durability is relatively poor, for this reason we propose a durable type cement bridge deck thin layer pavement structure and solve above problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a durable type cement bridge floor thin layer structure of mating formation, includes bridge floor basic unit, metalling, cured layer, buffer layer, cement pouring layer, the metalling is laid in bridge floor basic unit top, cured layer is laid in the metalling top, the buffer layer is laid in cured layer top, cement pouring layer is laid in the buffer layer top, bridge floor basic unit, metalling, cured layer, buffer layer, cement pouring layer constitute whole structure of mating formation, the structural expansion joint that leaves in advance of mating formation, the packing of expansion joint is with the elastic sealing layer, the elastic sealing layer top is equipped with the protective layer.
Preferably, the particle size of the broken stone of the crushed stone layer is 10-15mm, and the thickness of the crushed stone layer is 3-5 cm.
Preferably, the solidified layer is a metal grid mesh, and grid squares of the metal grid mesh are arranged in a size of 5 × 5 mm.
Preferably, the buffer layer is made of polyurethane high polymer material, and the thickness of the buffer layer is 10-15 mm.
Preferably, a plurality of drainage grooves are formed in the cement pouring layer at equal intervals, and the width of each drainage groove is 5-7 mm.
Preferably, the elastic sealing layer is polysulfide sealant, and the protective layer is a polyurea spraying layer.
Compared with the prior art, the beneficial effects of the utility model are that:
1. because the elastic sealing layer has good fuel oil resistance for the polysulfide sealing layer, hydraulic oil, water and various chemical properties and heat-resisting and anti-atmospheric aging performance, because the protective layer is polyurea spraying layer, the characteristic of polyurea is anticorrosive for the characteristic, waterproof, wear-resisting, can play fine guard action for the elastic sealing layer, the double-deck setting on polysulfide sealing layer and polyurea spraying layer has simultaneously strengthened the water-proof effects to the expansion joint, guarantee the durability of using, and polysulfide sealing layer and polyurea spraying layer are elastic material, can adapt to the expend with heat and contract with cold characteristic of bridge deck pavement structure.
2. The metal grid net is arranged to play a good role in connection and solidification, so that the tensile strength of the bridge deck is increased, and the elastic sealing layer is made of polyurethane polymer materials, so that the bridge deck has the characteristics of high resilience, high elongation and high strength, plays a good buffering effect, and effectively increases the shock resistance of the bridge deck.
