Izinto ezingangeni manzi ezisekelwe kusimende ezivumela ukuthi zikwazi ukungena emanzini seziphenduke into entsha eyinhloko engangeni manzi yesakhiwo sikakhonkolo esingaphansi komhlaba iphrojekthi yokuxhuma amanzi ngenxa yokusebenza kwayo okuphezulu okungangeni manzi, ukwakhiwa okulula, intengo enengqondo, ukuvikelwa kwemvelo kanye nezizathu ezingenabuthi nezinye.

Okokuqala, ukungangeni kwamanzi ukulwa nemifantu kakhonkolo
Njengoba sonke sazi, ukushiyeka okukhulu kwesakhiwo sikakhonkolo ukuqhekeka, ukuqhekeka kwesakhiwo kuzodala ukuvuza, ikakhulukazi ubunjiniyela obungaphansi komhlaba, ngenxa yokuguguleka komhlabathi isikhathi eside futhi kuzungezwe amanzi angaphansi komhlaba, uma eqhekeka, ukuvuza kubi kakhulu.
Nakuba ukwakhiwa kwesakhiwo sikakhonkolo ngokungeza i-admixture kungalawula ngempumelelo ukuqhekeka kwasekuqaleni kwesakhiwo, kodwa isakhiwo kumthwalo wokudlidliza, ukulahlekelwa kwamanzi kanye nokupholisa okubangelwa ukuhlaliswa, ukuncipha okomile nokuguga kokuqhekeka ukuvuza akulindelekile.
Inhloso yokungena kwamanzi iwukuba ukuqhekeka sekwephuzile kwesakhiwo ukuvuza, kuyisinyathelo sokuvimbela, okungukuthi, indlela yokuvimbela ukuqhekeka kwesakhiwo sikakhonkolo okubangelwa izici ezingaqinisekile ukuvuza ukwakhiwa okungenamanzi kunokubaluleka okusebenzayo.
Ngenxa yokwakhiwa kanye nezinye izizathu ezibangelwa isakhiwo sezinyosi, kwaqiniswa imbobo ukuvuza isenzakalo, esigabeni sokuqala ukwakheka ukuvuza kwesakhiwo waqala, okudinga ukusetshenziswa usimende permeable crystal enamathela amanzi ukuqinisa ingaphezulu lesakhiwo, ubuso besakhiwo buqinisiwe, ukuze kubambezeleke, kuvimbele ukuvuza futhi.

Izici ezimbili, ezisekelwe kusimende ezivumela ukuthi zikwazi ukumelana namanzi zekristalu
1. Dlala into engangeni manzi futhi uxhume ubulili obujwayelekile.Izinto ezingangeni manzi ezicwebezelayo ezivunyelekayo zingezempahla eqinile engangeni manzi, enokungangenisi kwesibili okungenakuqhathaniswa nokuhambisana nesakhiwo.
2. Amanzi ayisici esiyinhloko esinquma ukujula kwe-osmotic crystallization.Amakristalu akhiqizwe ukumbozwa okungangeni manzi angena kancane embotsheni yangaphakathi yesakhiwo ngokusebenzisa i-reflux ephazamisayo yamanzi phezu kwesakhiwo, ecebisa okuqukethwe kwekristalu ezimbotsheni ukwenza ubuso besakhiwo buminyene, futhi inombolo enkulu yamakristalu ahlala ezimbotsheni zokumboza ukuze amunce amanzi futhi andise ukunamathela okuminyene okungangeni manzi.
3. Qinisekisa ukujiya kokunamathela okungenamanzi ukuze kuzuzwe injongo yangempela yokungangeni kwamanzi.Uma izinto ezisetshenziswayo ezingangeni manzi ziyaqina, kushuba ukumbozwa kwamanzi, kuba nesikhala esiningi sokusabela kwe-hydration.
4. “Izinto ezicwebezelayo ezikwazi ukumelana namanzi ezisekelwe kusimende ezisekelwe kusimende” ngenxa yezici zekristalu evuvukalayo yamakhemikhali asebenzayo, ngokuhamba kwesikhathi, umphumela wawo wokungangeni kwamanzi uzoba ngcono futhi ube ngcono.
5. Ukwakhiwa okulula, asikho isidingo somunye ungqimba ovikelayo;Kulula ukuxubha, kulula ukwakha, kungakhiwa ngaphansi kwezimo ezimanzi.

Okuthathu, isilawuli sekhwalithi sokunamathela esingenamanzi esisekelwe kusimende
Okufanele kukhulunywe ngakho ukuthi ukuze kuthuthukiswe izinga elingenamanzi lokumboza, kungakanani ukusetshenziswa kwezinto ezibonakalayo ngemitha yesikwele futhi kuyisihluthulelo sokwenza umsebenzi omuhle ekwakhiweni kwamanzi.
Ikakhulukazi ezintweni ezingangenwa amanzi ezicwebezelayo ezisuselwe kusimende, kunenkinga yesikhala yokusabela kwe-hydration.Ngamanye amazwi, lapho inani lezinto ezingangeni manzi ziba mkhulu, ukujiya koqweqwe olungenwe amanzi, kuyanda isikhala sokusabela kwe-hydration;Incane yona.Isikhala esilinganiselwe sokusabela kwe-hydration futhi sinqunyelwe ukugqugquzela amakhemikhali asebenzayo ukuze akhiqize amakristalu e-osmotic engeziwe.
Ngakho-ke kufanele sigcizelele ukuthi ukujiya kokumboza ngokwesilinganiso "sobunjiniyela obungaphansi komhlaba obungangeni manzi" asikho ngaphansi kuka-1.5kg/㎡, ukujiya kufanele kube kukhulu kuno-1.0mm.Ukuze ufeze ngempela inhloso yokungangeni kwamanzi, kuyadingeka ukuthuthukisa ikhwalithi yokugqoka okungangeni manzi.I-Cement-based crystalline permeable waterproof materials ngenxa yokwakhiwa kwezinto ezilula futhi ngokuvamile ezilula ukwenza izisebenzi zokwakha zingayinaki le nkinga, okufanele ibangele ukunaka kwethu ohlelweni lokwakha.
