TPO自粘预铺防水系统在地下综合管廊中的应用探讨

Discussion on Application of TPO Self-adhesive Pre-laid Waterproofing System in Underground Utility Tunnel

现浇结构管廊防水设计中,以高分子为主体的防水材料应用越来越普遍。在造价相当的情况下,选用TPO自粘类防水卷材对管廊进行整体外包防护,针对管廊底板选用TPO高分子自粘胶膜预铺防水卷材,能够有效解决地下工程设防的难点,提高管廊防水的耐久性及可靠性。。

Among waterproofing designs of cast-in-place structured pipe galleries,the application of waterproofing material which takes polymer as the main component is getting more and more popular.Under the circumstance of similar cost,TPO self-adhesive waterproofing membrane is adopted for the overall external protection of pipe galleries,while TPO polymer film reinforced self-adhesive pre-laid waterproofing membrane is used for the floors.In this way,the underground waterproofing difficulties are effectively solved,and the waterproofing durability and reliability of pipe galleries are improved.
