Abstract
The invention discloses a sheet-shaped underground diaphragm wall structure. Temporary horizontal supporting rods and a permanent plate are commonly used as a horizontal support of underground diaphragm walls. The temporary horizontal supporting rods are divided into four layers, namely, the supporting rod S1, the supporting rod S2, the supporting rod S3 and the supporting rod S4. The permanent plate comprises a top plate and a gathering layer plate from top to bottom in sequence. Temporary vertical supporting rods and a foundation pile are commonly used as a vertical support. The sheet-shaped underground diaphragm walls are pulled and connected together through a cover beam. The underground diaphragm walls and a cast-in-place wall body are combined into a permanent wall body. According to the underground diaphragm wall structure, the connection is reliable, the whole structure is stable, the construction defects that joints of wall bodies in adjacent groove sections cannot be aligned and water leakage occurs are overcome, the construction period is shortened, the project cost is reduced, and the economical benefits are improved.
