Prestressed pipe pressure slurry is how casting

Prestressed pipe pressure slurry prestressed pipe pulp price prestressed pipe pressure prestressed pipe pressure slurry paste manufacturer of concrete pouring should make the following preparation work: according to the structure of mixed, environmental conditions and water quantity, make reasonable casting process scheme, process to deal with the didn't buy, pouring down the build tools, tearing a protective layer, control and the specific provisions. Response to the plate, steel and shall, within the template sundry, water, and the dirt from the steel should be cleaned up. With Europe or Kong Run, should be tight and not slurry wall. To cope with the uniformity of mixing performance such as detection and slump from high to dump coagulation and template, should prevent coagulation segregation. Direct dump, its free pour down 2 m height should not be more than 2 tons of used, should be in, flow tube ( Slot) Chute or vibration ( Slot) Facilities such as falling: pour down height of more than 10 m: wave loading. Concrete core according to certain thickness, sequence and direction of hierarchical system, and should be the next 戻 concrete initial setting or can complete upper coagulation and rebuild the casting; On the lower casting at the same time, the upper and the lower casting distance before and after 1 shall be maintained. More than 5 m: when the inclined surface concrete, should from the lower began to expand rise step by step, and maintain the level of stratification. Stratified pouring concrete prestressed pipe pressure slurry shoulds not be more than the thickness of the table, the rules of the 3. Table 6. 11. 3 concrete thickness of layered casting way casting layer thickness ( mm) By inserting type vibrator 300 with attached type vibrator 300 unreinforced or hydrophobic 250 will use the reinforcement and the surface of the vibrator reinforcement is close 150 the vibrator ofnon-vibrating concrete prestressed pipe pressure slurry, shall comply with the following provisions inserted type vibrator shift spacing shall not exceed vibrator action radius of 1. Five times, and the side form should keep a distance of 50, and insert the lower the depth in concrete appropriate is 50 ~ 100 mm
