The invention relates to an arrangement structure of a lattice-form underground continuous wall. The arrangement structure of the lattice-form underground continuous wall comprises longitudinal walls and transverse walls, wherein the axial lines of the longitudinal walls are perpendicular to a main load direction; the directions of the axial lines of the transverse walls are the same with the main load direction; the longitudinal walls comprise an inner-side longitudinal wall and an outer-side longitudinal wall; certain ends of the transverse walls are connected with the inner-side longitudinal wall, while the other ends of the transverse walls are connected with the outer-side longitudinal wall; one side, which faces to the outer-side longitudinal wall, of the inner-side longitudinal wall is provided with U-shaped joints; the U-shaped joints are embedded in the inner-side longitudinal wall, and are fixedly connected with a steel reinforcement cage in the inner-side longitudinal wall; the end parts of the transverse walls are embedded into groove bodies of the U-shaped joints; further, steel reinforcement cages in the transverse walls are fixedly connected with the U-shaped joints; one side, which faces to the inner-side longitudinal wall, of the outer-side longitudinal wall, is provided with second U-shaped joints; the second U-shaped joints are embedded into the outer-side longitudinal wall, and are fixedly connected with a steel reinforcement cage in the outer-side longitudinal wall; the end parts of the transverse walls are embedded into groove bodies of the second U-shaped joints; and further, the steel reinforcement cages in the transverse walls are fixedly connected with the second U-shaped joints.
