The invention relates to the technical field of inspection well covers, in particular to a stretchable type inspection well cover. The inspection well cover comprises an inspection well cover body, and an elastic layer is arranged on the periphery of the inspection well cover. By means of the device, the problem that peripheral gaps become large after the inspection well cover is used for a long time is effectively solved; and in addition, the elastic layer can be replaced, so that repeated using is guaranteed, and the cost is saved.
