AI Technical Summary
The connection method between sheet piles and capping beams in existing double-row retaining piles leads to poor soil pressure transmission, which can easily cause weld cracking and local stress concentration.
Two rows of sheet pile components are used. The sheet piles are connected to the capping beam through a connecting beam. The top of the sheet piles passes through the capping beam. The cast-in-place concrete structure avoids welding. The reinforcing bars are distributed above the sheet piles to enhance the connection strength, and the sealing is improved by clips.
It effectively transfers the pressure of sheet piles to the capping beam, reduces the risk of weld cracking, enhances connection strength, reduces the risk of water seepage, and is simple, economical and environmentally friendly to construct.
