Four reinforcing bars are first placed in support pile using bar planting mode by the postposition anchor production, and then steel plate and bar planting are welded
It connects.
The steel pipe uses the connection of support, steel pipe diagonal brace and built-in fitting, postposition anchor and is fully welded, and weld seam is not less than 8mm.
The construction process of the utility model are as follows: foundation slab structure construction；The installation of postposition anchor；It is Underground Construction, pre-
Embedded part is pre-buried；Steel pipe installs support, diagonal brace；Concrete support is removed；Basement construction finishes backfilling of earthwork；Steel pipe recycling.
The utility model has the following beneficial effects:
1, the utility model replaces traditional support replacement arrangement and method for construction with steel pipe underpinning technique, and success support replacement tears support open, overcomes often
See that support replacement mode removes the drawbacks such as long construction period caused by reinforced concrete inner support and personnel's work holdup, has expanded support pile
Application advantage of+the reinforced concrete inner support in Deep Foundation Pit Supporting Project, significant effect.
