PURPOSE: A gear-shaped soundproof block assembly is provided to facilitate assembly and simplify structure by integrating an inner tub, a partition wall, and an outer tub. CONSTITUTION: A gear-shaped soundproof block assembly comprises a soundproof block(110), a finishing block(120), a long bolt(150), and a nut(151). The soundproof block comprises an outer tub, an inner tub, a partition wall, and a first internal sound absorption material(140). The outer tub includes a convex part and a concave part, wherein both ends are opened. The inner tub is formed inside the outer tub. The partition wall is connected to the outer tub through the central part of the inner tub. The first internal sound absorption material is charged in a space between the outer tub and the inner tub.
