Ipayipi lensimbi likasimende elilwa nokugqwala libhekisela ekwelashweni okumelana nokugqwala kodaka lukasimende epayipini lensimbi ngaphakathi komzimba weshubhu.Ifakwe ulwelwesi lukasimende olwakhiwe ngepayipi lensimbi elilwa nokugqwala, ipayipi lensimbi eligcwele ukhonkolo, elingamunca ukushisa okuningi, ngakho-ke izinga lokushisa kwesigaba sokushisa kwesigaba sokushisa alilingani kakhulu, isikhathi sokumelana nomlilo kwezinsika, sinciphisa ijubane. izinga lokushisa lamakholomu ensimbi, futhi uma amakholomu ensimbi eveza ukhonkolo angamelana nomthwalo omningi we-axial ukuvimbela ukuwa kwesakhiwo.Kokumelana nomlilo we-beam ehlanganisiwe kuzophinde kwande, ngoba ukushisa okuphansi kwezinsimbi zensimbi kuzodlulisela ukushisa kusuka ku-flange phezulu kuya kukhonkolo.

Uhlaka lukasimende lodaka lodonga lwamapayipi kanye nokuhlukaniswa kwamanzi noma igesi, ukwakheka kongqimba oluqinile lokuvikela ukuvimbela i-oxidation kanye nokugqwala kodonga lwamapayipi kusuka ekungcoleni kwebhodlela.Uma kuqhathaniswa nezinye i-anti-corrosion coating, i-cement mortar kanye namandla ahlangene odongeni lwamapayipi, ngenxa yokuthi i-hydration yezinhlayiya ze-cement ukwakha ijeli, udonga lwangaphakathi lwepayipi yensimbi yamandla aqinile;Ukuncipha kwevolumu yodaka lukasimende induration eduze kwepayipi lensimbi Ukuhlela, ukukhiqiza ukungqubuzana;ukubambisana kokulunywa ngomshini phakathi kwepayipi lensimbi elingaphakathi elingalingani, ngodaka lukasimende.

Udaka lukasimende ngaphakathi kwenqubo yokusebenza kwepayipi le-anticorrosion:
Ingxube kasimende, isihlabathi namanzi ibizwa ngokuthi udaka lukasimende.Udaka lukasimende luka-1:3 luvame ukubhekiselwa kulo ngokuhlanganyela nengxenye eyodwa kasimende nezingxenye ezi-3 zesihlabathi, cishe azinakwa ukwakheka kwamanzi, ngokuvamile ngesilinganiso esingu-0.6, okufanele sibe u-0.6:1:3 izinjongo zodaka lukasimende ubuNjiniyela bokwakha, Okokuqala, isisekelo kanye nodonga lwamatshe, olusetshenziswa njengesihlanganisi sezinto ezinkulu zamatshe, njengemfucumfucu yephazili, isitini esibomvu sokusebenzisa udaka lukasimende;ukuplasta kwangaphakathi nangaphandle.Udaka lukasimende lapho lusetshenziswa, kodwa futhi ngokuvamile kuvame ukufakwa ezinye izithasiselo, njengama-micro-foaming agents, impushana yamanzi ukuze kuthuthukiswe ukusebenza kwayo kanye ne-viscosity.Ukwengeza ingxenye yamatshe, usimende udaka ukuze ube ukhonkolo.
