种植屋面复合防水层施工方法及质量控制

Construction Method and Quality Control of Planting Roof Composite Waterproof Layer

随着城市化进程的加快,城市居民对居住环境要求日益提高,绿色种植屋面应运而生。屋面防水是建筑工程中重要的一环,防水质量的优劣直接影响使用效果。其中复合防水层是指采用铺设多种的防水材料方式,充分发挥各类材料特点,以提高屋面防水的整体性、保障性。深圳市某水质净化厂工程厂区上部整体加盖覆土作为市政公园,需要对上盖做复合防水屋面处理,论文主要叙述了在该工程中采用的“沥青卷材+细石混凝土保护层+高密度聚乙烯排水板”复合防水层施工方法及其质量控制。

With the acceleration of urbanization,urban residents'requirements for living environment are increasing,and green planting roof came into being.Roof waterproof is an important part of construction engineering.The quality of waterproof directly affects the use effect.The composite waterproof layer refers to laying a variety of waterproof materials to give full play to the characteristics of various materials,so as to improve the integrity and guarantee of roof waterproof.As a municipal park,the upper part of the plant area of a water purification plant in Shenzhen is covered with soil as a whole.The upper cover needs to be treated with composite waterproof roof.This paper mainly describes the construction method and quality control of“asphalt coiled material+fine aggregate concrete protective layer+extruded drainage board”composite waterproof layer used in this project.
