Xiamen, Quanzhou, Zhangzhou Pressure slurry pipeline

Xiamen, Zhangzhou, Quanzhou pipeline pressure slurry coating raw 13,074,822,159 channel (pipe) pressure slurry in a special post-tensioned pipe (hole) grouting construction products from a variety of high-quality cement-based materials and high performance additives and optimum allocation Cheng, has excellent mobility, slurry stability, filling is good, setting time adjustable, no shrinkage, micro-expansion, high strength, non-hazardous substances and other characteristics of the steel. Apply the purpose of protecting prestressing tendons from corrosion, to ensure cohesion of security assurances and the prestressing tendons concrete structure between, so that the effective transmission of prestressing between them, make prestressing tendons and concrete joint action. Fatigue prestressed concrete structures under cyclic loading stress changes caused by the destruction of Anchorage, Anchorage prolong life and improve the reliability of the structure. 2 applications of various railways, post tensioned prestressed highway bridge Duct Grouting. Duct Grouting large prestressed structures. Various concrete structure stanch grout joints. Grouting, anchor grouting, filling gaps or repair. Application of Construction Points Construction Shi Shi water feed ratio of 0.26 to 0.28, can be adjusted according to different parts of the grout. First added to the actual mixing water in a blender for 80% -90%, starting mixer, a uniform slurry was added all the pressure, while adding while stirring. All powder addition was complete, then rapid stirring 3min, add the remaining 10% -20% of mixing water, stirring was continued for 2min. Pressure from the slurry and stir until pressed into the bore of duration, depending on the temperature conditions, are generally within the range of 30 ~ 1h. Pressure slurry before and pressure injection process should be continuously stirred to maintain a uniform slurry and mobility. Grouting pressure when using piston pump or vacuum pumps, pressure must be greater than 0.7MPa. The slurry temperature should be maintained at between 5 ℃ -30 ℃ when grouting, or should take steps to meet the conditions. Notes mixer speed of not less than 1000r / min. Due to the delay caused by the use of slurry flow was reduced, can not to increase its fluidity by adding water. Construction, at high temperatures, it should choose a lower temperature the time, such as night construction; at low temperatures, winter construction standards should be.
