濟(jì)南專業(yè)防水http://www.tianyujian.com/談到將卷材防水層粘貼在地下工程結(jié)構(gòu)的迎水面通常稱外防水，貼于背水面稱內(nèi)防水。卷材外防水可以保護(hù)地下工程主體結(jié)構(gòu)免受地下水有害作用的影響；防水層可以借助土壓力壓緊，并可和承重結(jié)構(gòu)一起抵抗有壓地下水的滲透。
Jinan professional waterproofing waterproofing membrane comes to be attached to the positive side of underground engineering structures usually called outer waterproof, affixed to the back surface of the water, said water-resistant.
Waterproof outer membrane of the main structure can be protected from the effects of underground harmful effects of groundwater; waterproof layer can make use of compacted earth pressure, and the load-bearing structure together and resist pressurized groundwater infiltration.
濟(jì)南專業(yè)防水http://www.tianyujian.com/介紹內(nèi)防水做法不能保護(hù)主體結(jié)構(gòu)，且必須另設(shè)一套內(nèi)襯結(jié)構(gòu)壓緊防水層，以抵抗有壓地下水的滲透，有時(shí)甚至需設(shè)置錨栓將防水層及支承結(jié)構(gòu)連成整體。因此，一般掘開(kāi)施工的地下工程都不采用內(nèi)防水做法，只是暗挖施工的地下工程，必須采用卷材防水而又無(wú)法采用外防水做法時(shí)，才采用內(nèi)防水做法。
Jinan professional waterproof waterproof introduce the practice has failed to protect the main structure, and must be a separate structure lined with waterproof layer pressed to resist pressurized groundwater infiltration, and sometimes
need to set anchor waterproof layer and the support structure integrally connected. Therefore, the general construction of dug underground engineering practices are not using waterproof, but the construction of underground tunneling project, waterproof membrane must be used with external waterproof but can not practice, practice before using waterproof.
