近年来,许多新建楼房都采用地热采暖方式,地热采暖楼房在楼梯间设有管道井,而在一些设计中,进户缓台处有管道从管道井经缓台铺设进户,管道基本为各户采暖分支管道覫32和各户自来水分支管道覫20(常见一梯三户缓台)或地热管由管道井分水器经缓台铺设进户(常见一梯二户缓台)。缓台铺设管道并完成细石混凝土面层后缓台标高增加5~7mm,造成在 In recent years, many new buildings have adopted the method of geothermal heating, geothermal heating buildings in the stairwell with a pipeline wells, and in some designs, Into the buffer station at the pipeline from the pipeline wells through the platform to lay households, the basic pipeline Household heating branch pipe 覫 32 and each household tap water branch pipe 覫 20 (common one ladder three households), or geothermal pipe by the pipeline well water separator laying by households (common one ladder two households Taiwan). After setting up the pipeline and completing the fine concrete surface, the elevation of the platform will increase by 5 ~ 7mm, resulting in
