Fabricated rail transit vibration isolation trench and construction method thereof

The invention discloses a fabricated rail transit vibration isolation trench and a construction method thereof. The vibration isolation trench comprises a trench body, a bottom plate arranged at the bottom of the trench body, supporting components arranged on the two sides of the trench body and a vibration isolation component arranged between the supporting components on the two sides. A plurality of supporting components are assembled for use and laid along the groove wall of the groove to form a supporting wall, and each supporting component comprises supporting panels which are used in pairs on the two sides and a cross brace arranged between the supporting panels on the two sides; the vibration isolation component comprises a vibration isolation shell arranged between the supporting components on the two sides, a buffer layer arranged on the periphery of the interior of the vibration isolation shell and a vibration isolation layer arranged in the vibration isolation shell. The supporting component and th
