Steel support can stay in the wall joint position, if not, then why?
1, to 2, in order: first the site even wall, etc. the wall concrete reached a certain strength, in the wall at the seams on the outside the foundation construction of high pressure jet grouting pile
The jet grouting pile is in even after the end wall construction construction, for fear of even the construction of wall joints is not perfect, there Water Leakage seams and other quality problems, in the wall at the seams (outside the foundation) to reinforce, most of the time without the need for jet grouting pile construction.
