Tangi yekuchengetera inoshandiswa kuchengetedza mvura kana gasi simbi yakavharwa mudziyo, tangi yekuchengetera tangi i petroleum, kemikari, zviyo nemafuta, chikafu, kudzivirira moto, chekufambisa, simbi, kudzivirira kwenyika uye mamwe maindasitiri akakosha masisitimu, ayo ekutanga zvinodiwa zvakare akanyanya kuomarara. . Nheyo yevhu yevhu inofanira kusangana nezvinodiwa zvekukosha kwekugadzira kwekutakura simba, uye inofanira kubatwa nesepage uye hunyoro-uchapupu, kana zvikasadaro kubuda kunokonzeresa kusvibiswa kwakakomba kune zvakatipoteredza, uye pasi pevhu mhute yemvura ichauya, uye tangi resimbi richaita ngura. Naizvozvo, HDPE tangi yemafuta isingapindire geomembrane ndiyo isingapindike uye hunyoro-humbowo zvinhu mune yakakosha dhizaini yekuchengetedza tangi.
Oiri tangi nzvimbo yakaisa impermeable geomembrane kuvaka tekinoroji:
1. Tangi remafuta risati ragadzikwa geomembrane, gwaro rinoenderana rekugamuchirwa reinjiniya yehurumende richawanikwa.
2. Usati wacheka, zviyero zvakakodzera zvinofanira kuyerwa zvakarurama, HDPE geomembrane inofanira kutemwa maererano nekucheka chaiko, kazhinji kwete maererano nehukuru hunoratidzwa, inofanira kuverengwa imwe neimwe, uye yakanyorwa zvakadzama pane fomu yakakosha.
3. Inofanira kuedza kupinza zvishoma, pasi pechikonzero chekuona mhando, sezvinobvira kuchengetedza mbishi zvinhu. Zviri nyore zvakare kuve nechokwadi chemhando.
4. The kupindirana upamhi musono pakati firimu uye firimu kazhinji kwete asingasviki 10cm, kazhinji kuitira kuti weld kurongeka kunoenderana nemateru, ndiko kuti, pamwe pamawere.
5. Kazhinji mumakona uye akaremara zvikamu, kureba kwemusono kunofanira kunge kupfupi sezvinobvira. Kunze kwezvinodikanwa zvakakosha, pamateru ane materu anopfuura 1:6, mukati me1.5 metres yekumusoro kutsetseka kana kushushikana kwenzvimbo, edza kusaisa welds.
6. Mukugadzika kwefirimu yemafuta isingapindiki, mapepa ekugadzira anofanira kudziviswa. Kana tembiricha yakadzikira, inofanira kusimbiswa uye kugadzirwa kusvika painobvira.
7. Mushure mekupedzwa kwegeomembrane isingagoneki kuisa, kufamba pamusoro pe membrane, zvishandiso zvekufambisa, nezvimwewo zvinofanira kuderedzwa. Zvinhu zvinogona kukonzera kukuvadza kune membrane isingapindike hazvifanirwe kuiswa pa membrane kana kutakurwa pa membrane kudzivirira kukanganisa netsaona kune membrane.
