The utility model relates to an embedding device for a soil pressure gauge of a soil slope. The soil pressure measuring device is used for measuring the soil pressure of a soil slope, a drilled hole is formed in the slope surface of the soil slope and comprises a vertical rectangular pipe, a concrete base surrounding the lower end of the rectangular pipe is poured at the bottom of the drilled hole, at least one cloth bag is fixedly arranged on the outer side of the rectangular pipe, and a soil pressure meter is arranged in each cloth bag. Sand layers completely covering the cloth bags are filled between the outer side walls of the rectangular pipes and the hole walls of the drilled holes, and the rectangular pipes are filled with fine aggregate concrete columns in a pouring mode. The soilslope soil pressure gauge embedding device solves the problems of no support structure, low test precision and the like when the soil pressure gauge is used for measuring the soil pressure in the slope, and has the advantages of convenience in embedding, high test precision and the like.
