The invention discloses a slope protection device for engineering investigation, and belongs to the technical field of engineering slope protection. A buffer seat and a buffer encapsulation layer are separated, so that when the slope protection device is impacted by falling rocks of a slope, the buffer encapsulation layer is used as a first buffer defensive line; the liquid buffer part in the buffer encapsulation layer is matched with an outer encapsulation, so that the impact force is counteracted, and the buffer encapsulation layer is protected by virtue of liquid fluidity; the falling rocks which partially counteract the impact force fall onto the buffer seat, and the buffer seat and a plurality of buffer bodies are used as a second buffer defensive line; the buffer seat is separated from the buffer encapsulation layer after being pressed downwards so as to impact the buffer bodies on the bottom end of the buffer seat, and the plurality of buffer bodies are evenly stressed, so that the downward pressing speed of the buffer seat is greatly reduced; and after an upper buffer layer is separated from the buffer encapsulation layer, the falling rocks can fall down through a gap formed between the upper buffer layer and the buffer encapsulation layer, so that the impact force of the continuous falling rocks on the buffer seat is further reduced, and the buffer seat and the bottom structure of the buffer seat are effectively prevented from being damaged under great pressure.
