Njengendawo eswakeme kakhulu ezindlini nasezindaweni zezentengiselwano, ikhwalithi yebhodi yokusekela engangeni manzi endlini yokugezela inquma ngokuqondile-ukuzinza kwesikhathi eside kwezindonga nephansi. Ikakhulukazi ngokusetshenziswa kabanzi-kwezindlela zokubeka ezacile kanye nokwakhiwa okwenziwe ngaphambilini, ukukhetha ibhodi eliyisipele elifanele elingangeni manzi kungavimbela izinkinga ezifana nokugeleza kwamanzi, amathayili angenalutho, nokukhula kwesikhunta ngokuhamba kwesikhathi. Amaphuzu alandelayo kufanele acatshangelwe lapho uthenga:
I. Ukusebenza Okubalulekile: Gxila "Ekuvimbeleni Manzi + Ukuqina" Isisekelo sebhodi elisekelayo elingangeni manzi liwumgogodla webhodi-weseli XPS extruded polystyrene material. Kuyadingeka ukuqinisekisa ukuthi izinga layo leseli elivaliwe-Likhulu noma lilingana no-99%, kanye nokuqinisekisa ukuthi izinga lokumuncwa kwamanzi embikweni wokuhlolwa Lingaphansi noma lilingana no-1.5% ({7}}imikhiqizo yekhwalithi ephezulu ingaba ngaphansi ngo-0.8%) futhi amandla okucindezela Amakhulu noma alingana no-300kPa. Le mingcele emibili inquma ngokuqondile ukuthi ibhodi lithambekele ekuguqukeni nasekuqhekekeni ezindaweni ezinomswakama. Ngaphezu kwalokho, ungqimba olungaphezulu lukasimende oluhlanganisiwe kufanele lube ne-fiberglass mesh ukuze kuqinisekiswe amandla okubopha nge-adhesive enamathelayo futhi kuvimbele ukuthi isiphetho singaxebuka kamuva.
II. Ukuvikelwa Kwemvelo Nokuphepha: Gwema Izingozi Zezinto Ezigaywe Kabusha Eminye imikhiqizo{1}}inenani eliphansi isebenzisa izinto ezigaywe kabusha esikhundleni sezinto ezisetshenziswayo ze-XPS ezingasenalutho, ezingakhulula izinto eziyingozi ngokusetshenziswa-kwesikhathi eside. Ngesikhathi sokuthenga, ukuhlola kokuqala kungenziwa kusetshenziswa indlela "elula{4}}yokuhlola okuthathu": iphunga (izinto ezintsha akufanele zibe nephunga elishisayo), ukukhanya kwe-UV ({5}}imikhiqizo yekhwalithi ephezulu akufanele ibonise i-fluorescence), kanye nomthelela webhola lensimbi (indawo engaphezulu akufanele idilike noma iqhekeke). Ngesikhathi esifanayo, qinisekisa ukuthi ukukhishwa kwe-formaldehyde Kungaphansi noma kulingana no-0.025mg/m³, okuhlangabezana namazinga ezempilo ezindawo zokugezela.
III. Ukuzijwayeza Kwendawo: Igumbi lokugezela{1}}Amapharamitha Akhethekile Awakwazi Ukugxunyelwa Ngaphansi Kwamagumbi okugeza adinga ukuhlangabezana nezimfuneko zokuvikela amanzi, ukumelana nesikhutha, nokuvala umsindo. Ngakho-ke, ukujiya kwebhodi okuwu-12-50mm kuyanconywa, futhi isilinganiso sokumelana nesikhutha kufanele sichazwe ngokucacile njengeBanga 0 (indawo yesikhutha Ingaphansi noma ilingane no-5%). Uma kusetshenziswa ukushisa okungaphansi, ukuqhutshwa kwe-thermal (okungcono kakhulu ngu-0.028-0.030W/M·k) kufanele futhi kucatshangelwe ukuze kugwenywe ukulahlekelwa ukushisa. Ezindaweni ezimanzi ezibalulekile njengezindawo zeshawa, beka phambili amabhodi okusekela azinikele anedizayini ye-drainage slope engu-2% ukwenza lula inqubo yokwakha.
IV. Ukwakha kanye{1}Nesevisi Yangemuva{1}Yokuthengisa: Izinsizakalo Ezisekelayo Zinquma Ukuqaliswa Kwemiphumela Ephezulu{2}}amabhodi asekelayo ekhwalithi adinga amanzi akhethekile{3}}okunamathelayo angangeni, ama-sealant, nezinye izinto ezisizayo. Lapho uthenga, qinisekisa ukuthi umphakeli angakwazi yini ukuhlinzeka ngesixazululo esididiyelwe "sezinto ezibonakalayo + zokwakha". Ngesikhathi esifanayo, qiniseka ukuthi iphutha lokucaba Lingaphansi noma lilingana no-2mm/m ukuze ugweme izindawo ezingenalutho ekufakweni kwethayela.
Uma uthenga amabhodi asekelayo angangeni manzi, gwema ukucabangela inani kuphela. Nakuba{1}izinto ezigaywe kabusha ezinenani eliphansi zingase zonga izindleko zokuqala, izindleko zokuphinda zisebenze ngokuhamba kwesikhathi zivame ukudlula inani lokuthenga. Kunconywa ukuthi ugxile "kumapharamitha + izitifiketi +{5}}ekuhlolweni kwesayithi," ukukhetha imikhiqizo enesakhiwo esiyinhlanganisela ye-XPS njengalesi esiboniswe esithombeni. Lokhu kulinganisa ukuvimbela amanzi, ubungane bemvelo, nokulula ukwakha, ukudala "udonga olungabonakali olungenamanzi" oluqinile lwendlu yokugezela.
