Izixazululo Zesisekelo Zamathangi Ensipho Ashunyiwe: Umhlahlandlela Wezobunjiniyela Nokuklama
Izitangi zensimbi eziboshwe ngezikulufu—ikakhulukazi lezo ezenzelwe izindinganiso ze-AWWA D103-09—zidinga isisekelo esinikeza ukwesekwa okuyisisekelo nokuvikelwa kwemvelo. Ngoba izitangi eziboshwe ngezikulufu zakhiwa ngamaphaneli ahlanganisiwe avalwe emingceleni, isisekelo kumele sibe sezingeni eliphelele futhi siqinile ukuze kuvinjelwe ingcindezi emalungeni epaneli. Ukukhetha uhlobo olufanele lwesisekelo kuyisinqumo esibalulekile sobunjiniyela esithinta impilo yesitangi, ubuqotho bezinto zokubopha, kanye nezindleko zokugcinwa kwesistimu yokugcina.
1. Izinhlobo Eziyinhloko Zesisekelo Zamathangi Ashunyiwe
A. Isisekelo Sodonga Lwendandatho Yakhiwe Ngokhokhelo
Unyaka wendandatho uyindinganiso yomkhakha wamathangi amakhulu ensipho ashunyiwe. Ukhokhelo oluqiniswe ngokhokhelo lwakhiwa ngaphansi komjikelezo we-tank ukusekela isisindo sesikhumba kanye nophahla. Ingaphakathi lendandatho ligcwaliswe ngesihlabathi esicindezelwe noma itshe elikhulu.
● Kungani isebenza: Inikeza indawo eqinile, eyisicaba ngqo ngaphansi kwesikhumba se-tank, lapho kugxile khona iningi lomthwalo wesakhiwo. Ivikela futhi isisekelo se-tank ekudleni komhlabathi nasekuvundululeni.
B. Isisekelo Sodonga Lwakhiwe Ngokhokhelo
Isetshenziswa ezindaweni ezincane ezinezinga eliphansi lapho umthamo wokubekezelela inhlabathi uphansi futhi idinga ukuthi isisindo sethangi lisakazwe endaweni enkulu ukuze kuvinjelwe ukwehla okungalingani.
● Kungani kusebenza: Kunikeza ukuqina okuhle kakhulu kwesakhiwo. Kodwa-ke, kudinga ubunjiniyela obunakekelayo bokudonsa amanzi ukuze kuqinisekiswe ukuthi amanzi akakheki ngaphansi kwesisekelo sethangi, okungadala "ukugoba" noma ukugqwala phansi kwethangi.
C. Isisekelo Esiphakeme (I-Pier/Pedestal)
Ezindaweni ezisengcupheni yezikhukhula noma ezindaweni lapho kudingeka khona ukuvikelwa okuphezulu ekugqwaleni, amathangi aboshiwe angaphakanyiswa ezindaweni eziqinisiwe ze-concrete noma izisekelo.
● Kungani kusebenza: Kuvikela ngokuphelele isisekelo sethangi emhlabeni, kuvumela ukujikeleza komoya, ukuhlola ingaphansi lethangi, nokutholwa okusheshayo kokuvuza ngokubonwayo.
2. I-Comparative Decision Matrix
Ukukhetha uhlobo olufanele lwesisekelo kuncike ezimweni zakho zomhlabathi, usayizi we-tank, nesabelomali.
Uhlobo Lwesisekelo | Umthamo Wesakhiwo | Izindleko | Isicelo Esingcono Kakhulu |
I-Gravel/Earth Pad | Phansi | Phansi | Amathangi amancane, ukusetshenziswa okwesikhashana |
I-Concrete Slab | Phakathi | Phakathi | Inhlabathi embi, amathangi aphakathi |
I-Concrete Ring Wall | Phezulu | Phakathi/Phezulu | Amathangi anobubanzi obukhulu (Okujwayelekile) |
I-Elevated/Pier | Phezulu | Phezulu Kakhulu | Izindawo ezisengcupheni yizikhukhula, izindawo ezinezindawo eziningi zokugqwala |
3. Izindlela Ezibalulekile Zobunjiniyela Ezihamba Phambili
Ukubaluleka Kokuba Nendlela Efanele
Ezitsheni zensimbi eziboshwe ngezikulufu, ukulingana kuyinto okungadingeki ukuthi kuxoxwe ngayo. Ngisho nokuhluka okuncane kakhulu ezingeni lesisekelo kungadala ukuthi izingxenye zensimbi ezihlangene zingahlangani kahle, okwenza kube yize ukufeza isitembu esingangeni manzi ezindaweni zokuhlanganisa. Abasolintrakta kufanele baqinisekise ukulingana kwesisekelo ngemishini yokulinganisa nge-laser enembayo kakhulu ngaphambi kokwakhiwa kwesitsha.
Ukuhambisa Amanzi Nokulawula Ukuvuza
Amatsheni aboshwe ngezikulufu athembele kumastiki akhethekile noma ama-gaskets lapho phansi kuhlangana nodonga. Uma amanzi evunyelwa ukuba agcwale azungeze isisekelo setanki, kudala umphumela wokudonsa amanzi ongaholela ekugqwaleni okungaphambi kwesikhathi kwezingxenye zetanki.
● Ithiphu Lokuklama: Isisekelo kufanele sibe nesilinganiso esincane (esihlehlisa amanzi kude netanki) ukuze kuqinisekiswe ukuthi amanzi angaphezulu ahambela kude nodonga.
Ukugcinwa Kwesibili
Ezindaweni eziningi zomthetho, amathangi ensimbi aboshwe ngezikulufu adinga ukuvalwa kwesibili. Isisekelo esiklanywe kahle somgqomo singafaka ungqimba lokuthola ukuvuza—uvame ukuba yinto eyenziwe ngendwangu (geofabric) noma imvamisa ephezulu—ngaphansi kophansi lwethangi ukuze ubambe noma yikuphi ukuvuza okungase kwenzeke kungakafiki endaweni ezungezile.
4. Imibuzo Evame Ukubuzwa (FAQ)
Q: Ngikwazi yini ukubeka ithangi lensimbi eliboshwe ngezikulufu ngqo endaweni enegravel?
A: Kuphela ezitsheni ezincane kakhulu noma izicelo zesikhashana. Izitshe ezinkulu ezinobubanzi obukhulu zakha ingcindezi enkulu endaweni ezungezile. Ukuzibeka ematsheni ngaphandle kodonga oluyindandatho lwe-concrete kuvame ukubangela ukuthi zihlehlise, zilahlekelwe ubude, futhi ekugcineni zivuze ezindaweni zokuxhuma zesitsha.
Q: Ingabe kudingeka imembrane engangeni manzi ezitsheni eziboshwe ngezikulufu?
A: Nakuba kungadingeki njalo ngokuya ngekhodi yokwakha, kuyatuswa kakhulu. Imembrane ihlinzeka "ngendawo yokushelela" ukunciphisa ukungqubuzana ngesikhathi sokunwebeka/ukuncipha okubangelwa izinga lokushisa futhi ivimbele umswakama ukuthi unganyukeli ku-concrete ungene phansi kwesitsha.
Q: Ngiziphatha kanjani izikulufu zokubopha?
A: Ezitsheni ezidinga ukubopha ngenxa yezinyikimo zomhlaba noma umoya, izikulufu zokubopha kufanele zifakwe odongeni oluyindandatho lwe-concrete noma i-slab ngaphambi kokuthi isitsha sibekwe. Kunzima kakhulu ukufaka izikulufu zokubopha ngemuva esisekelweni se-concrete esiqinile ngaphandle kokubeka engcupheni ukwakheka kwaso.
Isisekelo yisona "esifihliwe" esibaluleke kakhulu sezindleko zephrojekthi yethangi lensimbi eliboshiwe, kodwa futhi yisona esibaluleke kakhulu ukuze kuhlale isikhathi eside. Udonga oluqinile lwe-concrete olwakhiwe kahle lunikeza ukuqina nokulingana okudingekayo ukuze izingxenye zamamojula ethangi zisebenze njengoba kuhloswe. Ngokubeka phambili ukulungiswa kwesiza, ukulingana, nokudonsa amanzi, uqinisekisa ukuthi impahla yakho yethangi ihlala iphephile futhi ayivuze iminyaka eminingi.
Ngabe usezingeni lokuklama noma lokuthenga lephrojekthi yethangi lensimbi eliboshiwe, futhi ungathanda ukuxoxa ngokuhlolwa okuthile kwe-geotechnical okudingekayo kumandla okuthwala inhlabathi yesiza sakho?
