Double-layer composite waterproof and material blocking sealing structure for cable trench and switch cabinet

Abstract

The utility model discloses a double -deck composite waterproof material -stopping sealing structure for cable trench and switch cabinet, including a plurality of connecting plates, a plurality of connecting plate end is equipped with splicing head, and two adjacent connecting plates are mutually spliced through splicing head, and constitute the U shape structure of top opening, the trench body inner wall is coated with waterproof coating, and the waterproof coating is filled with foamed sealing layer between connecting plate. Advantageous effects lie in: connecting plate can realize quick and stable mutual splicing through the splicing head of end portion, and the installation process is simplified and the construction difficulty is reduced, the continuous closed waterproof coating of trench body inner wall can form the first reliable waterproof barrier in the trench body interior, effectively blocks the outside moisture from the seepage of trench body inner wall, and the elastic sealing foamed sealing layer filled between waterproof coating and connecting plate forms the second waterproof line of defense, and the overall sealing waterproof performance is greatly improved.
