Some Major Technical Measures about the Waterproof Construction of Underground Eletric Cable Room

银川市电信局南园分局通讯机房地下电缆室，基底标高－５．２６ｍ，室外地坪－１．８ｍ，地下水位在－２．８６ｍ处．为保证电缆室无一处漏水，在施工中采取了一系列措施：降低地下水位；注重特殊部位的处理；确保混凝土抗渗性能；注重ＳＢＳ改性沥青新型防水卷材的施工等。

The eletric room,communication room of Nanyuan Branch,Yinchuan Telecommunication Bureau,is -2.86m of underground water level,with the bottom of foundation level -5.26m and the ground level -1.8m. To prevent the linking of water, a series of measures have been taken during the construction, which include reducing the underground level,attaching importance to some special parts,making sure the imperious property of concrete and paying attention to the construction of SBS asphalt water-proof roll roofing et.
