近年来,随着老化下水道管渠的增加,相继开发了一些非开挖的翻新技术,以减轻对居民生活的影响,但在施工时须有大型机械设备,不仅影响交通,而且作业效率较低,此外,现有的管道与翻新材料之间的空隙,在注入填充材料时,只能依据填充材料的注入量进行确认。为此新近开发了一种采用透明塑料简体翻新老化大口径管渠的新技术,既省作业空间、提高效率,又可采用目测方法把握填充实况。
In recent years, along with the increase of sewer pipes and channels in the sewers, some non-excavation renovation technologies have been developed in order to reduce the impact on residential life. However, large-scale mechanical equipment is required during construction, which not only affects traffic but also has low operational efficiency In addition, the gap between the existing pipe and the refurbished material can only be confirmed by the filling amount of the filler when the filler is injected. To this end, a new technology for reconstructing aged large-diameter pipelines using transparent plastic has been recently developed. This not only saves space for operations and increases efficiency, but also allows for visual inspection of the filling conditions.
