The invention provides a rock wool board production workshop drainage pipe inspection well which comprises an upper well body and a lower well body, wherein the lower well body is communicated with the upper well body. The bottom of the upper well body is an inclined plane, the height difference of two ends of the bottom is 0.5-1%, reinforcing ribs are uniformly arranged at the bottom of the upper well body, drainage grooves are formed among the reinforcing ribs, continuous hydrophobic interaction columns are arranged in the drainage grooves, a water inlet pipe and a water return pipe are communicated with two sides of the top of the lower well body, heating parts are arranged on the outer side of the lower well body, the water inlet pipe is communicated with the bottom of the drainage grooves, and the water return pipe penetrates the side wall of the upper well body upwards and connected with a condenser. According to the inspection well, odor of the inspection well caused by long-term accumulated water and poor drainage is effectively prevented, the accumulated water in the inspection well can be recycled, a certain cost is saved, and installation stability of the drainage pipe is ensured when the accumulated water can flow.
