H - 60 prestressed pipe pressure slurry complete construction method

H - Prestressed pipe pressure slurry H - 60 H - 60 prestressed pipe pressure slurry manufacturer 1 and, structure within 48 H after administration in the process of the thing that the temperature and the temperature of the earth shall not 5 ℃, otherwise should adopt 収 heat preservation measures, H - 12 after grouting should through the inspection hole grouting selectiving examination of the father, if there are any false, H - 60 prestressed pipe pressure slurry should be dealt with in a timely manner for grouting. 13, after the completion of grouting should be on time for fixed end seal protection or preservative treatment, according to design requirements need the pin with a seal, H - 60 prestressed pipe pressure slurry should be completed in the grouting shoulder to end the state of concrete chisel to the area around the washing dry, steel casting closure for coagulation and Settings; Fault sealing and structure should be adopted or Yang, with the strength of the coagulation and seal the wrong to strictly control the length of the beam. Long-term exposed anchorage, rust prevention measures should be taken. 14 of post-tensioned prefabricated, shall not be in place before the hole grouting: H - After 60 prestressed pipe pressure slurry grouting, shall, in accordance with the provisions of grout strength to achieve the strength of the rear can be removed and hoisting. 15 the duct grouting construction record should be filled in. Record project should include: date of grouting materials, mixture ratio, grouting, the mixing time, initial fluidity, slurry temperature, environmental temperature, voltage stabilizing pressure and time, H - 60 prestressed pipe pressure slurry with vacuum shaft help fashion should include vacuum grouting process.
