PURPOSE: A soundproof wall for temporary construction is provided to improve soundproof effect by blocking sound wave movement. CONSTITUTION: A soundproof wall for temporary construction comprises followings. A joint of a double uneven structure is formed on both connection surfaces(1a,1b) of a main body of a soundproof wall for temporary construction(1) formed of synthetic resin extrusion boards Multiple mountain-shaped projections with a sound absorption space are formed on the inside of the main body of a soundproof wall for temporary construction. A sound absorption guide groove(3) with a V-shaped cross section is formed between the mountain-shaped projections. A sound absorption guide plate(2) with a through hole is attached on the bottom(3a) of the sound absorption guide groove. A sound absorbing plate(4) is installed inside the sound absorption guide plate.
