Problems solved by technology

Although the patented technology has a good waterproof effect, it has the problem of uneven dispersion of thermoplastic resin granules, and if the wind is strong during construction, the scattered synthetic resin granules will be blown away. In addition, special equipment such as melting tanks are required to heat and melt thermoplastic resin particles before spreading them, which increases the construction cost a lot

Embodiment 1

[0012] First coat a layer of primer on the bridge deck 2. The primer is epoxy resin paint. When painting the primer, spread light sand on the primer at the same time. The purpose of this is to prevent the deviation between the waterproof layer and the bridge deck. After the primer is painted on the bridge surface, apply the waterproof layer 3 again, the resin used for the waterproof layer of the present invention is polyurethane resin, and the brushing of the waterproof layer 3 adopts a roller to coat; layer 4, the configured plate layer 4 is made of a thermoplastic resin with a softening point of 100°C; after the plate layer 4 is paved, the last process is to add hot asphalt mixture Layer 5 is finished, and the asphalt and aggregate mixture that is usually used for paving is heated to 150°C and spread on the plate layer 4, so that the whole bridge deck waterproofing system has just been constructed.

[0013] The following is a routine performance test of the above-mentioned b...

Embodiment 2

[0016] First coat a layer of primer on the bridge deck 2. The primer is made of polyurethane resin paint. When the primer is painted, light sand is spread on the primer at the same time. The purpose of doing this is to prevent the deviation between the waterproof layer and the bridge deck. After the primer is painted on the bridge surface, the waterproof layer 3 is coated again. The resin used for the waterproof layer of the present invention is acrylic resin, and the brushing of the waterproof layer 3 adopts a roller to coat; After the plate layer 4 is finished, the configured plate layer 4 is made of a thermoplastic resin with a softening point of 120°C; after the plate layer 4 is laid, the last process is to add hot asphalt mixture The paving layer 5 is completed, and the asphalt and aggregate mixture that is usually used for paving is heated to 160° C. and paved on the plate layer 4, so that the whole bridge deck waterproofing system has just been constructed.

Abstract

Waterproof structure for deck and construction method thereof. The structure comprises down-to-up bridge floor and waterproof structure. The waterproof structure comprises waterproof layer, sheet layer, asphalt mixture spreading layer. The construction steps are: coating one coat priming paint on the bridge floor, which may be epoxide resin or polyurethane resin, coating waterproof layer which may be polyurethane resin, propylene-based resin, polyurea-formaldehyde resin or chloroprene resin, spreading sheet layer which may be produced by thermoplastic resin sheet or the fabric or non-woven fabric made of thermoplastic resin fiber or blended fiber containing most thermoplastic resin fiber, heating the common asphalt and aggregate mixture to 150-180 DEG C and spreading asphalt mixture layer on the sheet layer.

Description

technical field [0001] The invention relates to a waterproof structure for a bridge deck and a construction method thereof, in particular to a waterproof structure and a construction method for laying a waterproof layer on the surface of a steel bridge. Background technique [0002] Due to the influence of wind, frost, snow, rain and other climatic conditions on the surface of the steel bridge, its road performance gradually deteriorates and its service life is greatly shortened. Among the above-mentioned climate change factors, rainwater has the greatest impact on the bridge deck. Compared with the bridge deck that is often in a dry state, the fatigue life of the bridge deck that is often in a wet state is shortened by 1 / 1000, which affects the service life of the bridge deck and Among the many factors of road performance, the influence of water cannot be ignored, so bridge deck waterproofing is an effective means to maintain the durability of bridge decks. [0003] How to...
