一种仓格注浆结构及沉管
By setting grouting inlets and outlets on the side of the cell shell and pre-embedding grouting pipes in the upper part of the inner cavity, the problem of voids caused by the inability to grout the top surface of the cell was solved, achieving high-density grout filling and enhancing the overall strength of the cell.

AI Technical Summary
During immersed tunnel construction, if there are other structures or equipment and materials piled up on the top surface of the cell, grouting cannot be injected from the top surface, making it difficult to fill the side grouting completely. This results in large voids inside the cell and damages the overall strength.
A grouting inlet and a grouting outlet are set on the side of the outer shell of the cell, and a grouting pipe is pre-embedded in the upper part of the inner cavity. The grouting pipe has an opening, and grout is injected into the grouting pipe through the grouting nozzle. The opening is used to fill the upper space of the inner cavity, and the void problem is solved by side grouting.
It enables high-density grouting in cell blocks with structures or equipment on the top surface, reducing voids and enhancing the overall strength of the cell blocks.
