Abstract:

This article through to monitor the temperature of freezing shaft wall between learned about shaft wall in the set of a wall within 20 days after the end of the shaft wall is still positive temperature, and according to the borehole wall concrete strength increasing grouting pressure calculation between the wall, to ensure that the wall between the grouting effect, improve the wall between the compactness, think at the end of the set of wall to wall between grouting time is the best.

Key words: freeing, wall between grouting, temperature monitoring, grouting time
