On steel pipe reinforcing member is installed, steel pipe reinforcing member uses inverted trapezoidal structure, and steel pipe lower surface is equipped with isolation board, and steel pipe insertion is set
On isolation board.
For another example, Chinese utility model patent number 201420172843.5 discloses a kind of steel plate concrete open caisson, it includes
Open caisson wall, open caisson bottom plate, the open caisson wall include open caisson outer wall, open caisson inner wall and Concrete Filled layer between the two, it is also
Including high-pressure injection mechanism, the high-pressure injection mechanism is included by the sequentially connected high-pressure hydraulic pump of water lines, hydraulic-pressure regulating valve, spray
Firing association manages and high-pressure injection pipe, the injection manifold are horizontally fixed in the outer rim of open caisson outer wall, sprays manifold lower verticals
It is distributed some high-pressure injection pipes.
