Preventive Measures of Moisture Problems in High-quality Residential Underground Building
There are common phenomena in humid areas such as condensation on the inner surface of the walls,hairy mildew and ground moisture in the underground buildings during summer time.If in such humid environment for a long time,the service life of the building and its storage will be shortened accordingly,and the human health would be endangered by the breeding of mold.Therefore,the above problems of mildew and ponding in the underground buildings needs to be improved and solved urgently.In this paper,the generation mechanism of the above phenomenon such as condensation on the inner surface of the walls,hairy mildew and ground moisture in the underground building is analyzed,the physical mathematical model of the underground building envelope is established,the key factors affecting the thermal conductivity of the envelope structure are analyzed,and the improvement plans are compared.Then a preventive measure based on raising the inner surface temperature of the underground building wall is proposed,so as to avoid the above phenomenon caused by condensation in summer.The research results of this paper could provide technical guidance for the implementation of projects such as anti-condensation reconstruction of existing underground buildings,and also provide theoretical references for the research on anti-condensation envelopes of new buildings.
