Lattice-shaped underground diaphragm wall supporting structure under complex side slope environmental condition

The invention relates to the technical field of underground diaphragm walls, and discloses a lattice-shaped underground diaphragm wall supporting structure under complex slope environmental conditions, which comprises a plurality of wall units which are sequentially butted to form a whole, each wall unit comprises two T-shaped walls and a straight wall, each T-shaped wall comprises a transverse section and a belly section, the two ends of the linear wall are correspondingly in butt joint with the ends of the two belly sections respectively, and the two T-shaped walls and the linear wall form an integrated structure. Every two adjacent wall units enclose to form a wall middle area filled with soil. The lower parts of the wall units penetrate into the hard rock stratum; a T-shaped reinforcement cage is arranged in the T-shaped wall, and a linear reinforcement cage is arranged in the linear wall; an I-shaped joint is arranged at the end part of the transverse section; two ends of the I-shaped joint are respectiv
