The invention provides a management-and-protection-free integrated check dam and a construction method thereof. The check dam comprises a homogeneous earth dam body and a protection layer arranged onthe homogeneous earth dam body. The protection layer comprises an upstream slope protection layer, a downstream slope protection layer and a mixed material layer, and the mixed material layer is integrally connected with the upstream slope protection layer and the downstream slope protection layer. The construction method includes the steps that grinding and filling of the homogeneous earth dam body are conducted; mixed materials are prepared, the mixed materials are transported to the positions of the upstream slope protection layer and the downstream slope protection layer to be spread and subjected to grinding construction synchronous with the homogeneous earth dam body, and meanwhile lifting is conducted; various layers of draining blind pipes are buried; and filling of the mixed material layer is conducted.
