In izinsiza zikamasipala ezingaphansi komhlaba, uhlelo lwamapayipi agqitshwe isikhathi eside alufinyeleleki futhi alubonakali.Noma nini lapho izinkinga ezifana nokuguquguquka nokuvuza kwenzeka, akunakugwenywa ukuthi kudinga “ukuvulwa” ukuze kumbiwe futhi kulungiswe, okuletha ukuphazamiseka okukhulu ezimpilweni zezakhamizi.Ngenxa yalokho, kwavela ubuchwepheshe be-pipeline trenchless.
Ubuchwepheshe bokungambiwa bepayipi bubizwa ngokuthi "isu elincane elihlaselayo" ledolobha.Kuyindlela ephephile nesebenzayo yokwakha yokuvikela imvelo.Ingakwazi ukulungisa ngokushesha nangempumelelo izingxenye eziningi zepayipi ngesikhathi esisodwa ngaphandle kokumba okuningi., Ukulungisa, indawo yokulahla imfucumfucu.
Ubuchwepheshe bepayipi le-Trenchless buye benza ipayipi lokudonsa amanzi odongeni eliqinile le-HDPE elingenamsele, elilungele izindawo lapho ukumba kungeke kwenziwe khona futhi lihlangabezane nezidingo zokuthuthukiswa kwenethiwekhi yamapayipi okuphila yesimanje.
Isebenzisa i-polyethylene ephezulu-density njengempahla eluhlaza futhi yakhiwe ngokukhipha nokulinganisa kwe-vacuum.Izindonga zangaphakathi nezingaphandle zibushelelezi futhi ziyisicaba.Ayigcini nje ngokuhambisana nemvelo, kodwa futhi ihle kakhulu ekuphikiseni ukuqhekeka kwengcindezi, ukumelana namakhemikhali, ukumelana nomthelela wezinga lokushisa eliphansi, njll. Inezici zokumelana nokuguga futhi iphila iminyaka efinyelela kwengama-50, enciphisa kakhulu inani lepayipi. ukulungisa nokushintshwa, futhi ulawule ngempumelelo izindleko zobunjiniyela Ukusebenza nokunakekela.
Enye yezinzuzo zamapayipi okudonsa amanzi e-HDPE aqinile odongeni uhla olubanzi lokucaciswa.Ububanzi busuka ku-dn160-dn800, futhi ukuqina kwendandatho yi-SN8, SN16, ne-SN32, engahlangabezana nezidingo ezihlukene zobunjiniyela ngezinga elikhulu kakhulu.Ngesikhathi esifanayo, ukuxhumana kwayo okuphephile nokuthembekile kwenza inqubo yokwakha ibe lula futhi ibe lula.
Ngokwesisekelo sokungabhubhisi indawo yasemadolobheni, akuthinti ezokuthutha, ukungaphazamisi impilo evamile yabahlali, futhi ungaphazamisi amapayipi angaphansi komhlaba, njll., ukuhleleka komsebenzi womphakathi kuqinisekisiwe.Thuthukisa umphumela wokwakhiwa kwengqalasizinda yasemadolobheni futhi wenze idolobha lingavimbeki.
