近公司接到一个老垃圾填埋场渗滤液调节池渗漏土工膜修补的工程,为更好地解决和补救垃圾渗透液储存池土工膜存在的渗漏问题,我们经常反复研究制定以下方案: 12??>The company recently12|15??> received an old 27|24??> landfill leachate1|9??> regulating reservoirleakage geomembrane15??> repair engineering,18??> to better solve the132|3??> leakage135|9??> problems111|3??> and144|3??> remedial147|12??> landfill leachate159|9??> storage pool114|18??> of the geomembrane174|3??>,177|12??> we often189|12??> repeated study 201|12??> formulated the following 213|6??> plan1| ?? 219|3??>: 1、土工膜焊缝的处理,为防止土工膜焊缝有渗漏点,我们在取得领导同意并做现场试验决定用聚酯胎自粘防水卷材,对焊缝进行二次补救处理,采用宽度20cm厚度1.5mm的聚酯胎自粘防水卷材,对每条焊缝进行自粘,防范于未然。在施工过程中我们严格要求施工人员加大责任心把这次补救干好、干细,特别是在焊缝的表面处理上要干、要净,保证一次性粘结好。??>1|6?? 225|6??>Treatment 1 231|3??>,10|12?? 234|12??> geomembrane1?? 224|1??> seam 28|3?? 252|3??>, 31|9?? 255|9??> in order to prevent the 264|9??> geomembrane 273|6??> seam 279|3??> have 282|9??> leakage 291|3??>, 294|6??> we 300|9??> made in the15?? 309|15??> leadership agreed and100|3?? 324|3??> do103|12?? 327|12??> field test115|9??339|9??> decided to use124|9?? 348|9??> polyester133|18?? 357|18??> self-adhesive waterproofing membrane151|3?? 375|3??>,154|3?? 378|3??> two157|6?? 381|6??> remedial163|9?? 387|9??> treatment on the172|3?? 396|3??> weld187|3?? 411|3??>,190|6?? 414|6??> using 220|9?? 444|9??> polyester229|18?? 453|18??> self-adhesive waterproofing membrane196|10?? 420|10??> width 20cm 206|14?? 430|14??> thickness 1.5mm 247|3?? 471|3??>, 259|6?? 483|6??> for 265|6?? 489|6??> self-adhesive271|6?? 495|6??> on 250|9?? 474|9??> each weld 277|3?? 501|3??>, 280|9?? 504|9??> prevent 289|6?? 513|6??> the bud 295|3?? 519|3??>. 298|18?? 522|18??> During the construction process, 316|18?? 540|18??> we have strict requirements for 334|6?? 558|6??> construction 340|12?? 564|12??> personnel to increase the 352|9?? 576|9??> responsibility 361|9?? 585|9??> the 370|6?? 594|6??> remedial 376|6?? 600|6??> work 382|3?? 606|3??>, 385|6?? 609|6??> stem cells 391|3?? 615|3??>, 394|9?? 618|9??> especially to dry, to the net on the surface treatment12|9?? 636|9??> of weld1|6?? 645|6??>,15?? 672|15??> assure one-time bond1| ?? 472|3?? 696|3??>. 2、土工膜与管口的渗漏处理:针对管口存在的问题,我们施工人员反复研究并咨询了国内同行的施工经验,结合贵公司领导的建议,有贵公司出面协调HDPE管厂对东西两个管口进行延长封密,我们负责把两个管口行一次清理,随后用高分子沥青油进行浇灌,堵死渗漏点再用聚酯自粘防水卷材对表面进行粘结保护,加大安全系数。为预防水压增大,防渗土工膜与管口的挤压焊接承压问题,我们采用第三次包围管口的做法进行施工,施工人员在延长管口的内外径用防渗土工膜进行一次挤压焊接,再在管口周围用一大块防渗土工膜进行覆盖挤压焊接,这样能使管口内外径的防渗土工膜与管口外围防渗膜母体密实结合。 |
