AI Technical Summary

Technical Problem

The lack of effective protection when pipes penetrate walls leads to a shortened service life, increased project operation and maintenance costs, and may cause safety accidents.

Method used

The system combines materials such as waterstop strips, fireproof rock wool, asphalt hemp fiber, high-strength cement, and polyester fiber cloth to form a waterproof sealing layer and a rigid skeleton. The through-wall pipe is fixed by a support frame, and the protective sleeve and waterproof coating enhance the protective effect.

Benefits of technology

It effectively prevents moisture penetration and dampness erosion, extends the service life of through-wall pipes, reduces operation and maintenance costs, and improves safety.

Abstract

本实用新型公开了一种穿墙管道施工贯穿口防护结构，其包括设置在预埋套管和穿墙管之间的止水条：所述预埋套管预埋在墙体内部，所述止水条的表面设置有防火岩棉，所述预埋套管的内腔填充有沥青麻丝。本实用新型通过将包裹上止水条和防火岩棉的穿墙管放在支撑架上，使穿墙管贯穿预埋套管，使得支撑架能稳定穿墙管的放置位置，并且避免管道下垂拉扯填充层，进而使止水条和防火岩棉对穿墙管起到防水防潮的作用，随后再将沥青麻丝填充到预埋套管内，使其形成“柔性防水密封层”，接着再在沥青麻丝的两侧填充上高强度水泥，使其为缝隙处理提供“刚性骨架，接着再在左侧高强度水泥的表面涂上堵漏涂料，形成防水膜，即可达到延长穿墙管使用寿命的目的。
