Induction joint drainage channel device and mounting method thereof

The invention provides an induction joint drainage channel device and a mounting method thereof. The induction joint drainage channel device comprises a drainage channel and sealing pieces. The drainage channel is formed below an induction joint in the direction of the induction joint, and the position from the first end of the drainage channel to the second end of the drainage channel is away from the induction joint gradually. The drainage channel is hoisted on wall bodies on the two sides of the induction joint, and intervals are formed between the induction joint and the wall bodies and filled with the sealing pieces. According to the induction joint drainage channel device, the structure is simple, accumulated water at the induction joint can be real-timely discharged, leakage is avoided accordingly, the influence of the accumulated water on the strength and stiffness of the wall bodies on the two sides of the induction joint is reduced, and the structural safety of the wall bodies on the two sides of th
