To realize reinforcing cage construction of
underground diaphragm in narrow and complex construction site, a new type of
underground diaphragm wall reinforcement is put forward, which is named as pilewall.
In this paper, the formula of the pilewall design
method is deduced, the construction process is simulated and compared with the
monitoring results. Finally, the design method of pilewall
structure is formed, and the advantages and disadvantages of piletype wall structure, traditional underground diaphragm structure,
and shelter pile structure are comparatively analyzed in terms of bending
capacity. The results show that compared with the traditional underground
diaphragm structure, the pilewall structure needs
1.27~1.58 times of steel bars, which ensures a significant improvement in
flexibility during construction and provides guidance and reference for the
design and construction of deep foundation pit retaining structure in narrow or
complex sites.
