Examples

Referring to fig. 1 and 2, the present embodiment provides thin steel deck pavement structures 100, which are suitable for being laid on a bridge deck 200 of a slow traffic system bridge 10, and include a concrete base layer 110, a waterproof layer 120 and a pavement layer 130 that are sequentially laid on the bridge deck 200.

Wherein, the concrete base 110 is used for putting the slope for the beam bridge deck 200, because when processing the beam bridge deck 200, it is the flat slope, in order to reach the effect of bridge deck drainage, in this embodiment, through laying the concrete base 110 on the beam bridge deck 200 to concrete base 110 lays along the length direction of beam bridge deck 200 and is the structure of high both sides low in the middle. Such structure can realize both sides drainage, and the drainage effect is better, can effectively avoid ponding on the bridge floor.

Specifically, in the embodiment, the thickness of the middle part of the concrete is 10-12cm, and the thickness of the two sides of the concrete is 5-7 cm. And the middle and two sides of the concrete are in arc transition. Through the slow transition of arc, can promote the travelling comfort of bridge floor, avoid producing obvious slope and feel.

Waterproof layer 120 is used for preventing the corrosion of steel bridge deck, can also avoid the layer 130 of mating formation to soak water for a long time and influence life-span simultaneously, therefore, in this embodiment, set up waterproof layer 120 between concrete base layer 110 and the layer 130 of mating formation, the waterproof layer 120 can not be soaked to the moisture on layer 130 surface of mating formation, and then effectively avoid the inside ponding of layer 130 of mating formation, furthermore, ponding can not soak concrete base layer 110 from waterproof layer 120, the bridge deck 200 of concrete base layer 110 below can not be corroded more, the dry and comfortable nature of bridge deck 200 has effectively been kept, promote the life of bridge deck 200.

In order to avoid damage to the waterproof layer 120 caused by the paving machine in the paving process of the subsequent paving layer 130, in this embodiment, the waterproof layer 120 is a rigid cement-based waterproof material, specifically, a K11 waterproof paint.

The active ingredients in the k11 waterproof coating can permeate into capillary pores in a cement base surface, generate micro cracks and chemical reaction, permeate into a substrate and crystallize to form compact waterproof layers 120, can cover hairline cracks (smaller than 0.4 mm), resist slight shock, can be constructed on a wet base surface, can be directly pasted with ceramic tiles and other subsequent processes without a mortar protective layer, has the advantages of high impervious compressive strength and waterproof function of a negative water surface, is non-toxic and harmless, can be directly used for drinking pools and fish ponds, has the function of depression and mildew growth and can prevent the pollution of moisture salt to facing surfaces.

The paving layer 130 comprises a primer 131, a gravel layer 132 and an anti-pollution layer 133, wherein the primer 131 is paved on the surface of the waterproof layer 120, the gravel layer 132 is paved on the surface of the primer 131, and the anti-pollution layer 133 is paved on the surface of the gravel layer 132.

The primer 131 is quick-drying cement, which can further seal air holes, cracks and other defects of the concrete base layer 110 and the waterproof layer 120 and has a bonding effect with intermediate layer particles.

The crushed stone layer 132 is formed by laying ceramic particles, and glue is filled among the ceramic particles during laying; the thickness of the crushed stone layer 132 is 6-10 mm. The crushed stone layer 132 in this embodiment is a main structural layer of the pavement layer 130, and can be made of different colors by using ceramic particles of different colors according to actual needs, so as to enhance the aesthetic property of the bridge deck.

The antifouling layer 133 is formed by laying particles having a particle diameter of 1 to 75 um. It can play antiskid, dustproof effect.

In this embodiment, adopt the great ceramic granule of particle diameter to mix with glue and form rubble layer 132, adopt the less granule of particle diameter to mix with glue as antifouling layer 133 afterwards, it can guarantee that antifouling layer 133 still has the efficiency of definite drainage, and rubble layer 132 is because the particle diameter is great, ponding is easily discharged, and can not soak waterproof layer 120, can advance the comfort level of step promotion bridge floor, and the granule of antifouling layer 133 is little, and the granular sensation is less strong, tramples and feels better comfortable.

The existing bridge deck pavement scheme is designed by large bridges, a basic asphalt layer, the bridge section and the bearing capacity of the existing slow traffic system are small, the traditional bridge construction scheme is not applicable, but different from the traditional pedestrian overpass, and has higher requirements on bridge deck pavement.

In addition, the present embodiment also provides slow-moving traffic system bridges 10, wherein the thin steel deck pavement structure 100 is laid on the beam deck 200.

To sum up, the utility model provides a slim steel bridge deck pavement structure 100, through utilizing the slope that concrete layer adjusted the bridge face, make the drainage performance of bridge floor excellent, set up waterproof layer 120 after that and can not follow waterproof layer 120 and dip concrete base 110 in ponding, more can not corrode the bridge floor 200 of concrete base 110 below, the dry and comfortable nature of bridge floor 200 has effectively been kept, promote the life of bridge floor 200, can also avoid mat formation layer 130 long-term bubble water and influence life-span simultaneously, and mat formation layer 130's three layer construction, can satisfy the structural requirement, slim mat formation can also play fine antiskid, dustproof effect.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
