Waterproof and leaking stoppage structure of wall bushing

A waterproof leaking stoppage structure of a wall bushing is characterized in that a plugging filling layer, a water-absorbing expansion waterproof layer, an oil hemp thread leaking stoppage fixing layer, a rubber water stop strip sealing layer and a reinforcing sealing leveling layer are sequentially bonded and are bonded with the wall bushing and a pipeline into a whole, and five waterproof leaking stoppage procedures are matched with one another; a water source is prevented from entering the interior of a building through the wall bushing, the leakage problem is solved fundamentally, and the reliability and durability of waterproof leakage stoppage are guaranteed. 一种穿墙套管防水堵漏结构，通过设置封堵填充层、吸水膨胀防水层、油麻丝堵漏固定层、橡胶止水条密封层、加固密封找平层，上述各结构层依次粘接并与穿墙套管和管道粘接成为一体，采用五道防水堵漏工序相配合，防止水源通过穿墙套管进入建筑内部，从根源处解决了渗漏问题，保证了防水堵漏的可靠性和持久性。
