Fyt-1 bridge deck waterproof material, Puyang City, Henan Province, local manufacturers quote how much 1 ton
stay In bridge construction, the high pier construction step is surveying and setting out. Its accuracy has a certain impact on the later construction progress and quality. Therefore, the construction personnel are required to invest more energy. The construction personnel need to determine and mark the bridge pier column centerline and structural line according to the construction drawings and plans. In actual work, the spacing deviation between the pier column and the centerline needs to be strictly controlled, The deviation value of engineering control spacing in the project overview is less than 10mm, thus providing convenience for later construction. In addition, the construction personnel need to clean and tidy the pile top of the pier column, and remove the laitance on the surface of the concrete structure within the structural line of the pier column, so as to facilitate the later connection of reinforcement.
Fyt-1 Bridge deck waterproof coating product details
FYT-1 improved waterproof coating (HS-27), It is a kind of polymer composite material, which uses special domestic asphalt or imported petroleum asphalt as the main raw material, together with various surfactants and various chemical additives SBS thermoplastic rubber is used as auxiliary raw material to produce a new composite waterproof coating, which is modified by adding more high molecular polymer resin.
I Construction process of fyt-1 bridge deck waterproof coating for cement concrete surface:
1. Foundation surface treatment before construction
The newly built concrete bridge deck should have a 7-day curing period, and it is recommended to adopt sand blasting and shot blasting.
（ 1) First of all, the bad attachments on the road surface shall be removed, and the sand and debris on the road surface shall be cleaned. The positions with oil stains shall be specially treated, which can be dissolved by solvent;
（ 2) After the road is cleaned, the shot blasting machine is used for treatment, so as to remove the laitance and some sundries that are not firmly supported on the road, and at the same time make the road cleanliness and roughness meet the requirements;
（ 3) The interface can be completely purged and dried by professional hair dryer.
2. Foundation surface treatment requirements
The surface of cement concrete shall be dry and clean, free of laitance, pollutants, looseness, peeling, hollowing and serious cracking, and the interface shall be completely dry.
3. Fyt-1 bridge deck waterproof coating distribution
（ 1) Material consumption: 0.3kg-0.6kg/m two .
(2) After the interface is clean and completely dry fyt-1 Construction. Manual coating and spraying can be used.
Manual coating: before construction, pour it into a container of appropriate size and mix it slightly 3-5 min, the operator shall use the roller to evenly coat it on the cement concrete or other disposal base surface. This method is generally recommended. The roller coating shall be as uniform as possible;
Spraying construction: when the area is not large, the construction can be carried out manually with a spray gun, and the staff can hold the spray gun to evenly apply. When the area is large, the asphalt distributor can also be used for distribution, but the distribution amount needs to be strictly controlled, and the distribution needs to be uniform. Note that when spraying construction is adopted, the pipeline should be cleaned in time after the distribution to avoid blocking the pipeline. At the same time, attention should be paid to mixing evenly when using large barrels to prevent air from pouring in.
remarks: In order to achieve good construction effect, Gabriel Fyt-1 bridge deck waterproof coating It needs to be implemented in two times, and the time interval between the first and second implementation at room temperature is The asphalt layer can be constructed after 4~8h and 12 hours of construction.
II The construction process of fyt-1 bridge deck waterproof coating for base course surface:
1. Foundation surface treatment before construction
Before spraying, the base course shall be completely cleaned manually, and the sundries and floating dust on the surface of the base course shall be removed. If there is mud, it can be washed with a water truck.
2. Base treatment requirements
The surface of the base course must be free of sundries, dust, laitance, etc., and the surface should be completely dry.
III Precautions for construction of fyt-1 bridge deck waterproof coating:
（ 1) During construction, the foundation surface needs to be treated. The surface of the base surface shall be dry and clean, and the surface shall be free of loose laitance, peeling, hollowing and serious cracking. The oil stain shall be removed with solvent.
（ 2) Manual coating or mechanical spraying can be used for construction. The coating shall be uniform and air invasion shall be prevented.
（ 3) The construction amount needs to be adjusted according to different pavement conditions.
（ 4) The temperature during construction is 0~40 ℃. It is not suitable for construction in rainy days, strong wind and freezing weather.
（ 5) Smoking and all fireworks shall be prohibited during construction.
keep in storage: The product shall be stored for six months Warehouse above 0 ℃ shall be protected from sunshine in summer.
Package weight: Plastic drum package weight 50 kg.
