Roof-out pipeline waterproof structure and construction method
The waterproof structure comprises a roof concrete top plate, a pre-buried protective pipe pre-buried in the roof concrete top plate and a pipeline located on the inner side of the pre-buried protective pipe, and micro-expansion fine aggregate concrete is arranged between the pipeline and the pre-buried protective pipe. A leveling layer, a waterproof coiled material and a waterproof protection layer are sequentially arranged above the roof concrete top plate from bottom to top, the waterproof coiled material wraps the outer side of the pre-buried protection pipe, a plugging cover is installed on the top of the pre-buried protection pipe, a sealing ring is clamped between the plugging cover and the pre-buried protection pipe, and the inner ring of the sealing ring is arranged on the outer side of the pipeline in a sealed and sleeved mode. The plugging cover is installed on the outer side of the pipeline, the sealing ring clamped between the plugging cover and the pre-buried protective pipe is arranged on the outer side of the pipeline in a sleeving mode, the inner diameter of the sealing ring is smaller than the outer diameter of the pipeline in a natural state, when glue is not injected for use, the middle of the sealing ring is arranged in an upward bulging mode, and when the pipeline deforms, the bulging part can be used as compensation; and the waterproof effect is ensured when thermal expansion and cold contraction occur.
本发明公开一种出屋面管道防水结构，包括屋面混凝土顶板和预埋于屋面混凝土顶板内的预埋护管以及位于预埋护管内侧的管道，所述管道和预埋护管之间设置有微膨胀细石混凝土，屋面混凝土顶板的上方由下至上依次设有找平层、防水卷材和防水保护层，防水卷材包裹于预埋护管的外侧，预埋护管的顶部安装有封堵罩，封堵罩和预埋护管之间夹持有密封环，密封环内环密封套装于管道的外侧。通过在管道的外侧安装有封堵罩，经过封堵罩和预埋护管之间夹持的密封环套装于管道的外侧，自然状态下密封环的内径小于管道的外径，当不注胶使用时，将密封环的中部向上鼓起布设，当管道出现变形时能够利用鼓起部分作为补偿，保证出现热胀冷缩时仍具备防水效果。
