1. Vandudza migwagwa
Kune nzira dzakawanda dzekushandisa geosynthetics muzvikamu zvemigwagwa nechinangwa chekupa migwagwa kuita zvirinani uye hupenyu hurefu hwesevhisi, kana zvese zviri zviviri. Kana geotextiles uye geogrids zvichishandiswa munzvimbo dzakasiyana dzemugwagwa, mabasa e geosynthetics ndeaya:
Geotextiles anoshandiswa pakuzviparadzanisa uye kusimbisa eembankments nemibhedhi yemigwagwa;
Geogrid inoshandiswa kusimbisa embankments uye migwagwa;
Geogrids anoshandiswa kune lateral kusimbisa mukati meembankments.
Kuvandudzwa kutsva munzvimbo iyi kuwedzera kwemafibhi anoenderera panguva yekuvakwa kwemigwagwa. Saizvozvo, ma microgrids anogona zvakare kushandiswa mukufamba. Miedzo yemukati neyemumunda yakaitwa mune izvi. Parizvino, kubudirira kwave kuri kushandiswa kwemafibhi akaparadzirwa (kazhinji polypropylene) mumatombo emigwagwa.
Kubudirira kweramangwana kushandisa geosynthetics kurapa makomba mumibhedhi yemigwagwa. Mune iyo nzira, wick drainage inotanga kurongwa mugomba, acupuncture isiri-yakarukwa jira rinoiswa pawick drainage, uye yozodzorerwa kumashure nefiber-yakasimbiswa ivhu. Nzira yacho inovimbisa uye inomirira miedzo yemunda.
2. Hapana groove pombi kugadzirisa
Zvivako zveguta racho zvinogara zvichisakara, uye zvokuvakisa zvava nemazana emakore zvavapo. Kugadzirisa uchishandisa grooveless tekinoroji iindasitiri iri kusimukira, uye vese vanoshandisa polymeric zvinhu.
Sezvo nzira dziripo dzose dzinoderedza hukuru hwepakutanga pombi network, kufambira mberi kwezvino ndekwekusvina pombi yepakutanga ne-high-pressure probe kuti iwedzere dhayamita. Zvadaro, pombi itsva inokurumidza kuiswa uye yakarongwa. Nenzira iyi, kukwanisa kwepombi yepakutanga haina kuderedzwa. Mune zvimwe zviitiko, hupamhi hwepombi hunowedzerwawo.
Kuomerwa kwakatarisana neazvino grooveless pombi kugadzirisa nderekuti lateral kuonana hakugone kuumbwa, uye lateral yemahara yekuvuza mapoinzi anoumbwa. Mune ramangwana, kuoma uku kunogona kugadziriswa nemudziyo uri kure wekudzora mukati meiyo yekucheka system, iyo isingangopfuure nepapombi nyowani, asi zvakare inowana yakakwana lateral kusangana nerobhoti inotevera.
3. Ivhu uye Mvura Yekuchengetedza System
Kukukurwa kwevhu kunokanganisa kushandiswa kwevhu neminda yekurima, uye chimwe chezvikonzero zvekusvibiswa kwemvura. Kuti udzore, udzikise uye udzivise kukukurwa kwevhu, nzira dzakawanda dzekudzora kukukurwa kwevhu dzine chekuita negeosynthetics dzakagamuchirwa.
Iyo inogona kuitika mune ramangwana ndeye kushandiswa kwepamusoro-simba geosynthetic meshes (yakakwirira-simba geotextiles kana geogrids) kudzivirira mavhairasi. Mhedzisiro yedambudziko ndeyekufungidzira masimba, zvinzvimbo uye kurongeka kwegridi uye zvinhu zvekumisa, pamwe nekuwedzeredza induction munzvimbo dzine mamiriro ekunze.
