A construction method of a flexible buffer waterproof traffic lane structure of a traffic roof comprises the following steps:

step 1, construction preparation: (1) preparing materials: the cement-based capillary crystalline layer 21, the polymer modified asphalt waterproof coating layer 22 special for roads and bridges and the modified asphalt waterproof roll material layer 23 special for roads and bridges must be accompanied by product specifications and quality inspection reports. When the material enters the field, the material is sampled and tested again according to the standard specified by the specification. The cement-based capillary crystalline layer 21 and the polymer modified asphalt waterproof coating layer 22 special for roads and bridges are arranged in batches every 10t, and the modified asphalt waterproof coil material layer 23 special for roads and bridges is arranged in groups every 10000 cubic meters in a sampling inspection mode, and the like. Can be used by qualified parties after being checked. Unqualified products are strictly forbidden to be used in building engineering; (2) technical preparation: deepening a design drawing, performing computer pre-arrangement on the special modified asphalt waterproof roll material layer 23 for the road and the bridge by using a CAD deepening design tool, and pre-arranging the joint positions and the long and short edge positions so as to facilitate accurate blanking on site and save materials; after each layer of construction is finished, checking and accepting, and making the root and the internal and external corners of the pipe into circular arcs; the performance and technical indexes of the used waterproof material are mastered, and the special parts are controlled in a key way;

step 2, constructing the waterproof reinforced concrete slab structure 1; laying a waterproof reinforced concrete slab structure 1 as a base layer of the whole traffic lane; before the concrete is finally set, regular and uniform napping treatment is carried out on the surface of the concrete so as to achieve better effect;

step 3, constructing a cement-based permeable crystallization layer 21: (1) base layer treatment: the waterproof reinforced concrete plate structure 1 is subjected to base layer treatment before the construction of the cement-based capillary crystalline layer 21, the surface of the waterproof reinforced concrete plate structure 1 is firm, clean and flat, floating slurry, alkali return, dust and oil stains on the surface of the waterproof reinforced concrete plate structure 1 are removed by a steel wire brush, a chisel or a grinding machine, and defects, cracks and honeycomb pitted surfaces on the surface of the waterproof reinforced concrete plate structure 1 are chiseled and cleaned. Cleaning the pitted surface part of the honeycomb until fresh stones are exposed, and washing the pitted surface part with water; a 2cm gamma 2cm groove is formed at the root of the tube; the wall-through bolt needs to be chiseled to a protective layer thickness, and then the bolt rod is cut off. And finally, cleaning the surface ash with a high-pressure water gun. (2) Coating construction: after the base course is processed, the cement-based capillary crystalline layer 21 is coated on the waterproof reinforced concrete slab structure 1, and when the coating is carried out, the semi-hard nylon brush is used, so that the back-and-forth longitudinal and transverse brushing is uniform, the concave-convex part can be coated and the thickness is uniform, the bottom leakage is avoided, the accumulation is avoided, the uniformity is ensured during the coating, and the coating is not repeatedly carried out. The painting time is twice, and the amount of painting for one time is 0.75 kg/square meter. It is not suitable to brush too much once to avoid the problems of too thick coating and difficult maintenance. It is not suitable to brush too little to avoid the pulverization caused by too thin coating and too fast water loss. The second pass was performed when the first pass coating had reached a preliminary cure (about 2 hours) and was still wet. If the coating which is painted for the first time is dried and whitened, a layer of misty water is sprayed on the coating for wetting, and then painting construction for the second time is carried out. When the male and female corners are constructed, the male corners are brushed, the female corners and the concave parts cannot be deposited too thickly, otherwise, the piled parts can crack. The construction can not be carried out in the rain or when the environmental temperature is lower than 5 ℃, and the construction in the open air in hot days needs to avoid insolation, preferably in the morning and evening or at night, so as to prevent the coating from drying too fast to cause surface peeling and cracking and influence the penetration.
