Detailed Description
Example 1:
referring to fig. 1 to 5, the condensation-preventing foundation of the outdoor ring main unit comprises a lower foundation wall 1, a lower foundation plate 2, an upper foundation wall 3, an upper foundation plate 4 and a partition wall 5, wherein the structures are prefabricated or poured to form the condensation-preventing foundation as a main building structure forming the foundation.
Be equipped with down foundatin plate 2 on the foundation wall 1 down, be equipped with foundation wall 3 on the lower foundatin plate 2, be equipped with foundatin plate 4 on the last foundation wall 3, be equipped with partition wall 5 between lower foundatin plate 2 and the last foundatin plate 4.
Because foundation wall 1 is the pond form down, forms lower floor's space between lower foundation wall 1 and the lower foundatin plate 2, is equipped with cable 6 in the space of lower floor, and the cable 6 of laying underground penetrates or wears out in the space of lower floor.
Because the upper foundation wall 3 is annular, an upper space is formed among the lower foundation plate 2, the upper foundation wall 3 and the upper foundation plate 4. The vertical partition wall 5 partitions the middle of the lower space, so that the upper space is divided into an upper left space and an upper right space by the partition wall 5.
Through the crisscross fender that separates of multilayer anyhow, separate the moisture layer upon layer and keep off, avoid the moisture in the lower floor space to pass through the cable and get into the ring box with a net to avoided the looped netowrk incasement humidity too high, improved the stability and the security of looped netowrk case operation.
The cable 6 is last to overlap respectively the cover be equipped with lower foundatin plate 2, partition wall 5 and go up foundatin plate 4 complex sealed cover subassembly 8, realize through sealed cover subassembly that the sealed of clearance department keeps off between cable 6 and each structure, guarantees sealed effect. The sealing sleeve component on the upper foundation plate 4 needs to penetrate through the ring main body 7, and the ring main body 7 is positioned.
The seal cover assembly 8 comprises a cover body 802 penetrating through the structure body, an outer seal strip is arranged between the cover body 802 and the structure body, an inner seal strip is arranged between the cover body 802 and the cable 6, the outer seal strip and the inner seal strip are waterproof rubber strips, and sealing of a gap between the cover body and the cable and a gap between the cover body and the structure body is achieved through the inner seal strip and the outer seal strip.
