Kwemakore mazhinji, iyo yakakura dhayamita (16 inches uye pamusoro) yemvura pombi musika yakamiririrwa neSimbi Pipe (SP), Precast Concrete Cylindrical Pipe (PCCP), Ductile Iron Pipe (DIP) uye PVC (Polyvinyl Chloride) pombi.Kune rimwe divi, HDPE pombi inongoverengera 2% kusvika 5% yemusika muhombe wepombi yemvura.
Ichi chinyorwa chine chinangwa chekupfupisa nyaya dzekuziva dzine chekuita nehupamhi hwehupamhi hwemapaipi eHDPE uye kurudziro yekubatanidza pombi, mafittings, saizi, dhizaini, kuisirwa, uye kugadzirisa.
Sekureva kwemushumo weEPA, nyaya dzekuziva dzakatenderedza dhayamita hombe HDPE pombi dzinodzika kusvika pamapoinzi matatu.Kutanga, pane kushayikwa kwese kwekunzwisisa kwechigadzirwa.Mumapurojekiti emanisipala, huwandu hwevabatanidzi hunogona kuomesa kuendesa ruzivo kune zvigadzirwa zvine hukama.Saizvozvo, vashandi vanowanzo shandisa zvigadzirwa zvakajairika uye matekinoroji.Chekupedzisira, kushaikwa kweruzivo uku kunogona kutotungamira kune pfungwa isiriyo yekuti HDPE haina kukodzera kushandiswa kwemvura.
Dambudziko rechipiri rekuziva rinobva papfungwa yekuti kushandisa zvinhu zvitsva kunowedzera njodzi, kunyangwe kana ruzivo rwuripo.Vashandisi vanowanzoona HDPE sechigadzirwa chitsva chekushandisa kwavo chaiko, kunze kwenzvimbo yavo yekunyaradza nekuti havana ruzivo nazvo.Mutyairi mukuru anodiwa kugonesa zvishandiso kuyedza zvishandiso zvitsva uye maapplication.Zvinonakidzawo.
Nzira yakanakisa yekukunda matambudziko anofungirwa aya ndeyekubatsira kuyera njodzi dzinofungidzirwa uye kuratidza mabhenefiti angagoneke ekushandisa zvinhu zvitsva.Zvakare, zvinogona kubatsira kutarisa nhoroondo yezvigadzirwa zvakafanana mukushandiswa.Semuenzaniso, gasi rinoshandiswa rave richishandisa polyethylene pombi kubva pakati pemakore ekuma1960.
Kunyangwe zviri nyore kutaura nezve emuviri nemakemikari zvimiro zveHDPE pombi, imwe nzira iri nani yekubatsira kuyera mabhenefiti ayo kutsanangura zvimiro zvayo zvine chekuita nezvimwe zvepombi.Muongororo yezvishandiso 17 zveUK, vaongorori vakatsanangura avhareji yekukundikana kwemhando dzakasiyana dzepombi.Avhareji yekukundikana kwehuwandu pamakiromita makumi matanhatu nemakiromita kubva ku20.1 kukundikana pamucheto wakakwirira wepombi yesimbi kusvika ku 3.16 kukundikana pamucheto wakaderera wePE pombi.Chimwe chinonakidza chakawanikwa cheshumo ndechekuti imwe yePE yakashandiswa mumapombi yakaitwa makore anopfuura makumi mashanu apfuura.
Nhasi, vagadziri vePE vanogona kugadzira yakasimbiswa yepolymer zvimiro zvekuvandudza inononoka kuputika kukura kuramba, kusimba simba, ductility, inobvumirwa hydrostatic kusagadzikana, uye zvimwe zvinhu zvepombi zvinhu.Kukosha kwekuvandudzwa uku hakugone kuwedzeredzwa.Munguva ye1980s ne2000s, ongororo yekugutsikana kwemakambani ekushandisa nemapombi ePE yakachinja zvakanyanya.Kugutsikana kwevatengi kwakatenderedza 53% muma1980, ichikwira kusvika 95% muma2000.
Zvikonzero zvikuru zvekusarudza HDPE pombi zvinhu zvemadhiyamita makuru ekutepfenyura mains zvinosanganisira kuchinjika, fusible joints, corrosion kuramba, kuenderana ne trenchless tekinoroji nzira dzakadai seyakatwasuka nzira yekuchera, uye mari yekuchengetedza.Pakupedzisira, mabhenefiti aya anogona chete kuwanikwa kana nzira dzekuvaka dzakafanira, kunyanya fusion welding, dzinoteverwa.
