沿海地区地表水位较高,房屋地面一般都会发生“返潮”现象,特别是在春、夏、秋3个季节,地下潮气上升,一般水泥砂浆地面防潮效果差,严重时室内地面会出现水珠,给用户带来不便。我们在某工程施工中,对地面防潮做了改进,效果较好。具体做法是:在灰土夯实后,平铺一层普通塑料布,然后施工混凝土垫层,做面 The surface water level in coastal areas is relatively high, and the phenomenon of “flood” generally occurs on the ground of houses. Especially in the three seasons of spring, summer and autumn, underground moisture rises. Generally, the moisture-proof effect of the ground surface of cement mortar is poor. Inconvenience to users. In the construction of a certain project, we improved the ground moisture protection and achieved better results. The specific approach is: after the lime soil is compacted, lay a layer of ordinary plastic cloth, and then construct concrete cushions to make the surface
