AMP-100 second-order reactive bridge deck waterproofing adhesive double rainbow waterproofing

Description :

　　The Yinchuan Airport Yellow River Extra Large Bridge, constructed by China Railway Construction Bridge Engineering Group, has successfully passed the bridge deck acceptance inspection

　　According to China Railway Construction Bridge Engineering Group, headquartered in Tianjin, the bridge deck construction of the Yinwu High speed Railway Yinchuan Airport Yellow River Extra Large Bridge, which was constructed by China Railway Construction Bridge Engineering Group, has recently passed the acceptance inspection of the Yinwu Passenger Dedicated Line Engineering Construction Command, marking the entry of the Yinchuan Airport Yellow River Extra Large Bridge into the ballast laying construction stage.

　　The Yinwu Passenger Dedicated Line Yinchuan Airport Yellow River Extra Large Bridge is a key and difficult control project of Ningxia's first high-speed railway. It starts from Hedong Airport in the east and ends in the southern part of Yinchuan in the west, spanning both sides of the Yellow River in the middle, with a total length of 13814 meters and a main bridge length of 1200 meters. The total project cost is 1.67 billion yuan and the total construction period is 14 months.

　　The acceptance team believes that the construction of the ballast wall and concrete meets the design specifications, and the waterproof overlap width and laying process of the bridge deck meet the requirements.

　　This acceptance marks the official start of ballast laying construction for the Yellow River Bridge at Yinchuan Airport, and also means that the construction task of the Yinwu Project Management Department of the group has basically ended.

　　Product description

　　The "Shuanghong" brand AMP-100 second-order reactive bridge deck waterproof adhesive is a new type of polymer composite waterproof material. This product is a single component viscous liquid made by adding petroleum based reactive substances to a blend of natural asphalt and petroleum asphalt. Petroleum based reactive substances undergo copolymerization physical and chemical reactions when fully exposed to reactive gases such as O2 and SO2 in the air at a certain specific surface area, which is the first-order reaction stage of the product; At this stage, a certain strength of elastic adhesive material is generated, which can prevent construction vehicles and asphalt concrete paving equipment from damaging the waterproof bonding layer. During the process of laying hot asphalt concrete, the elastic gel waterproof bonding layer reacts at high temperatures, and the large aggregate is embedded in the elastic waterproof bonding layer to form shear bonds, playing a good role in bonding and shear resistance. After the paving is completed, the second-order reaction of the product is completed, forming a higher elastic-plastic waterproof bonding layer. It is a revolutionaryBridge deck waterproof coatingDue to its excellent performance and mature technology, it has been widely used in road and bridge waterproofing projects across the country.

　　Product advantages

　　(1) Reactive type: It has the unique one-stage and two-stage reaction process of AMP-100 second-order reactive bridge deck waterproof coating, which forms a highly elastic and plastic waterproof bonding layer after curing, and has excellent high and low temperature resistance performance;

　　(2) Excellent waterproof effect: After use, the product can play a waterproof role in stages during the first-order and second-order reaction processes.

　　(3) Curing effect: It can penetrate to a certain depth on the surface of cement concrete, fully react with alkali substances in cement concrete to form a nail effect.

　　(4) Strong bonding performance: The bonding and shear forces with cement concrete or asphalt concrete can reach over 1.0MPa, effectively preventing the occurrence of pavement delamination, displacement and other diseases.

　　(5) Construction simplicity: It can be sprayed or rolled, with simple construction, short construction period, and strong puncture resistance.

　　Scope of Application

　　Suitable for waterproofing projects such as highway bridges, urban overpasses, and culverts, it can prevent steel corrosion caused by water seepage on concrete bridge decks and improve the service life of beams.

　　construction technology

　　1. Preparation of construction tools: Before construction, mixing buckets, spraying machinery, or specialized bristle brushes should be prepared.

　　2. Grassroots requirements: The concrete strength of bridge decks and beams should meet the design grade, and there should be no loose floating slurry, peeling, hollowing, or severe cracking on the surface. The surface flatness should meet the requirements of bridge specifications, and the upper opening layer of the vertical drainage pipe should be installed firmly without any looseness.

　　3. The waterproof base should be clean, dry, and free of accumulated water.

　　4. Base treatment: The bridge deck must be free of dust, floating ash, impurities, oil stains, etc. Before laying the waterproof layer, the surface can be cleaned with an air compressor, water purifier, degreaser, etc. If there are hardened debris such as concrete and mortar, they should be polished off.

　　5. Construction steps of waterproof layer: (taking three coatings as an example)

　　A) Before painting, the bucket of paint should be stirred evenly. B) Before applying a large area of paint, use a small brush to apply two coats of paint to the leak, strengthen the application of waterproof paint to the corners three times, and then apply a full coat of paint to the floor over a large area. C) After the coating is dry, the second coat of coating can be applied. D) After the second coat of paint is dry, apply the third coat of paint.

　　Reference dosage and precautions

　　1. When the dry film thickness of waterproof membrane is 1mm, the dosage is 1.9kg/m2, and the coating thickness of bridge deck is generally around 0.5mm-0.7mm, with a dosage of 1.0-1.5kg/㎡. The actual dosage depends on the specific substrate conditions.

　　2. This product is suitable for use in an environment between 5 ℃ and 35 ℃. During the construction process, it must be protected from rain, hot sunlight, and frost.

　　3. If there is precipitation, it does not affect the quality. Stir well and it can be used normally.

　　4. Material storage: High temperature exposure is strictly prohibited. If the bucket lid is opened, it should be sealed immediately after use; Pay attention to antifreeze at 0 ℃.

　　Packaging, Storage, and Transportation

　　1. The outer packaging is in plastic drums.

　　2. During transportation and storage, products of different types and specifications should be stacked separately and not mixed together. Avoid direct sunlight and rain, and pay attention to ventilation.

　　3. Under normal transportation and storage conditions, the storage period is one year from the date of production.
