1, road and bridge waterproof coating before spraying, the main operation steps are as follows:
(1) Before spraying the bridge deck waterproof material, the concrete laitance shall be chiseled away, the uneven place shall be leveled, the oil stain and waste shall be removed, then the datum plane shall be thoroughly cleaned, and then the datum plane shall be blown clean by replacing the vacuum cleaner.
(2) When spraying a layer of bridge deck waterproof material, a certain amount of surfactant aqueous solution should be added to the architectural coatings for dilution, so as to promote the mixing of architectural coatings and porous pores at the grass-roots level, thus improving the bonding compressive strength and tensile strength of moisture-proof coatings. Then spray the building waterproof coating three times to ensure the waterproof effect.
(3) In order to prevent the environmental pollution caused by architectural coatings, the crash barrier was partially painted. When the bridge deck waterproof material is painted, the anti-collision guardrail shall be protected by two people. Therefore, the floor waterproofing at the bottom of the crash barrier is hand-brushed.
2, the common problems in the construction:
(1) Before the application of architectural engineering coating technology, mix it evenly.
(2) The bridge deck waterproof coating cannot be constructed in rainy days.
(3) During the whole construction process, it is forbidden to wet the ground, so as not to affect the waterproofing.
(4) After the bridge deck is waterproof, it should be strictly maintained. After waterproof grounding, vehicles under 10t can be put into use, but emergency braking is not allowed. Trucks, forklifts and cranes weighing more than 10 tons are prohibited from passing.
