The invention discloses a
water leakage prevention sealing strip for a cable pit cover plate. The sealing strip mainly comprises a sealing strip base (1) with a T-shaped longitudinal section, and is characterized in that a plurality of
layers of symmetrical or asymmetrical waterproof tooth edges (3) are arranged on the two sides of an
insertion trunk (2) of the T-shaped sealing strip base (1). The sealing strip has the advantages that 1, a
flame-retardant modified fluorosilicone material is elastic, and the waterproof tooth edges (3) are bent into V-shaped security strips, and are tightly attached to the wall of seams (7), so that
water leakage and the inflow of foreign matters are prevented in multiple levels, a good sealing effect is achieved, the interior of a pit is kept clean, safety is ensured, and the pit can be inspected and accepted once; 2, the sealing strip is convenient to
mount and replace, so that simplicity and convenience in power inspection, maintenance and first-aid repair are ensured; 3, the
flame-retardant modified fluorosilicone material is nontoxic, fireproof and
flame retardant, and the sealing strip is convenient to construct and reusable, and is an environment-friendly product; and 4, color can be used as a safety sign for the sealing strip, and a good effect is achieved.
