Anti-skid adsorptive sealing device

The invention relates to an anti-skid adsorptive sealing device. A through hole where a wire penetrates a soil pressure box is formed in the soil pressure box; a sealing device for sealing the gap between the wire and the through hole is arranged between the wire and the soil pressure box; the sealing device comprises a seal cover tightly coating the wire and an adsorption hood hermetically covering the through hole, the inner part of the adsorption hood is hollow, the top end and the bottom end of the adsorption hood are opened, and the area of the opening in the bottom end of the adsorptionhood is greater than that of the opening in the top end of the adsorption hood; the adsorption hood is a soft hood; the top end of the seal cover is tightly fixed to the wire, the bottom end of the seal cover is hermetically connected to the opening in the top end of the adsorption hood, the bottom end of the adsorption hood is tightly adsorbed and fixed to the outer surface of the soil pressure box through a negative pre
