建筑质量控制中,外墙防渗漏是控制的主要部分,外墙渗水对建筑整体结构的稳定性会造成影响,同时也影响建筑的美观性。但是在实际施工中,受施工技术、人为因素的影响,外墙渗漏问题是建筑施工中经常出现的问题。本文针对建筑外墙渗透问题出现的原因进行分析,在此基础上对防渗漏施工技术进行研究。 In the construction quality control, the external wall anti-seepage is the main part of the control. The water seepage of the external wall will affect the stability of the overall structure of the building and also affect the aesthetics of the building. However, in actual construction, due to the influence of construction technology and man-made factors, the problem of external wall leakage is a frequent problem in construction. In this paper, the reasons for the emergence of building external wall infiltration analysis, on the basis of the anti-leakage construction technology research.
