Geomembrane yedhamu remvura

Tsananguro pfupi:

Mageomembrane anoshandiswa pakuvaka madhamu ekuchengetedza mvura akagadzirwa nezvinhu zvepolymer, kunyanya polyethylene (PE), polyvinyl chloride (PVC), nezvimwewo. Zvinhu izvi zvine mvura shoma uye zvinogona kudzivirira mvura kuti isapinde. Semuenzaniso, polyethylene geomembrane inogadzirwa kuburikidza nepolymerization reaction ye ethylene, uye chimiro chayo chemamorekuru chakamanikana zvekuti mamorekuru emvura haakwanise kupfuura nepakati payo.

Mageomembrane anoshandiswa pakuvaka madhamu ekuchengetedza mvura akagadzirwa nezvinhu zvepolymer, kunyanya polyethylene (PE), polyvinyl chloride (PVC), nezvimwewo. Zvinhu izvi zvine mvura shoma uye zvinogona kudzivirira mvura kuti isapinde. Semuenzaniso, polyethylene geomembrane inogadzirwa kuburikidza nepolymerization reaction ye ethylene, uye chimiro chayo chemamorekuru chakamanikana zvekuti mamorekuru emvura haakwanise kupfuura nepakati payo.

1.Hunhu hweKushanda

Kushanda kwekudzivirira kubuda kwemvura:
Uku ndiko kushanda kwakakosha kwe geomembranes mukushandisa madhamu ekuchengetedza mvura. Geomembranes dzemhando yepamusoro dzinogona kuva ne permeability coefficient inosvika 10⁻¹² - 10⁻¹³ cm/s, zvichiita kuti mvura isapinda zvachose. Kana tichienzanisa nevhu rekare rinodzivirira kuyerera kwemvura, simba rayo rinodzivirira kuyerera kwemvura rinoshamisa zvikuru. Semuenzaniso, pasi pekumanikidzwa kwemusoro wemvura kwakafanana, huwandu hwemvura inoyerera negeomembrane hunongova chidimbu chidiki cheiyo kuburikidza nevhu rinodzivirira kuyerera kwemvura.
Kushanda kwekudzivirira kuboorwa:
Munguva yekushandiswa kwema geomembranes pamadhamu ekuchengetedza, anogona kuboorwa nezvinhu zvakapinza zvakaita sematombo nemapazi ari mukati memuviri wedhamu. Ma geomembranes akanaka ane simba rakawanda rekudzivirira kuboorwa. Semuenzaniso, mamwe ma geomembranes ane fiber reinforcement layers anogona kudzivirira kuboorwa. Kazhinji, simba rekudzivirira kuboorwa kwema geomembranes akakodzera rinogona kusvika 300 - 600N, zvichiita kuti asakuvadzwe nyore nyore munzvimbo yakaoma yemuviri wedhamu.
Kuramba Kukwegura:
Sezvo madhamu ekuchengetedza mvura achigara kwenguva refu, ma geomembrane anofanira kuramba kukwegura zvakanaka. Mishonga inodzivirira kukwegura inowedzerwa panguva yekugadzira ma geomembrane, zvichiita kuti arambe achishanda zvakanaka kwenguva yakareba pasi pesimba rezvinhu zvakaita semwaranzi ye ultraviolet uye kuchinja kwekushisa. Semuenzaniso, ma geomembrane anogadziriswa nemafomula akakosha uye matekiniki anogona kushanda kwemakore makumi matatu kusvika makumi mashanu ari kunze.
Kuchinjika Kwekuchinja:
Dhamu richasangana nekukanganisika kwakadai sekugadzika uye kuchinjika panguva yekuchengetwa kwemvura. Ma geomembrane anogona kuchinjika nekukanganisika kwakadaro pasina kutsemuka. Semuenzaniso, anogona kutambanudzwa nekukotama kusvika pamwero wakati pamwe nekugadzika kwemuviri wedhamu. Simba rawo rekudhonza rinogona kusvika 10 - 30MPa, zvichivagonesa kutsungirira kushushikana kunokonzerwa nekukanganisika kwemuviri wedhamu.

jira rinoita kuti jira rienderane nezvinodiwa neprojekiti. Ukobvu hwe geomembrane hunowanzova 0.3mm kusvika 2.0mm.
- Kusapinda: Iva nechokwadi chekuti geomembrane ine kupindira kwakanaka kudzivirira mvura muvhu kuti isapinde muchirongwa.

2. Pfungwa huru dzekuvaka

Kurapa Kwekutanga:
Usati waisa ma geomembrane, hwaro hwedhamu hunofanira kunge hwakati sandara uye hwakasimba. Zvinhu zvakapinza, masora, ivhu rakaremara uye matombo ari pamusoro pehwaro zvinofanirwa kubviswa. Semuenzaniso, kukanganisa kwekutsetseka kwehwaro kunowanzo fanirwa kudzorwa mukati me ±2cm. Izvi zvinogona kudzivirira geomembrane kuti isakwekwe uye kuve nechokwadi chekuti geomembrane nehwaro zvinobatana zvakanaka kuitira kuti irege kunyura.
Nzira yekuisa:
Mageomembrane anowanzo batanidzwa ne welding kana bonding. Pakusanganisa, zvakakosha kuve nechokwadi chekuti tembiricha yekusanganisa, kumhanya uye kumanikidzwa kwakakodzera. Semuenzaniso, kune mageomembrane ane welded heat-welded, tembiricha yekusanganisa inowanzo kuve pakati pe200 - 300 °C, kumhanya kwekusanganisa kunenge kuri 0.2 - 0.5m/min, uye kumanikidzwa kwekusanganisa kuri pakati pe0.1 - 0.3MPa kuti ive nechokwadi chekuti welding yakanaka uye kudzivirira matambudziko ekudonha anokonzerwa nekusanganisa kusina kunaka.
Kubatana kwePeripheral:
Kubatanidzwa kwema geomembrane nehwaro hwedhamu, makomo ari kumativi ese edhamu, nezvimwewo pamucheto pedhamu kwakakosha zvikuru. Kazhinji, migero yekunamira, kuvharwa kwekongiri, nezvimwewo zvichashandiswa. Semuenzaniso, mugero wekunamira une kudzika kwe30 - 50cm unoiswa pahwaro hwedhamu. Mupendero we geomembrane unoiswa mugwaro rekunamira uye unosimbiswa nezvinhu zvevhu zvakamanikana kana kongiri kuitira kuti geomembrane ibatane zvakasimba nezvivakwa zvakakomberedza uye kudzivirira kubuda kwemvura.

3. Kugadzirisa uye Kuongorora

Kugadzirisa Nguva Dzose:
Zvakakosha kugara uchitarisa kana paine kukuvara, kubvaruka, kuboorwa, nezvimwewo pamusoro pe geomembrane. Semuenzaniso, panguva yekushanda kwedhamu, vashandi vekugadzirisa vanogona kuita ongororo kamwe chete pamwedzi, vachitarisa pakutarisa geomembrane munzvimbo dzine mvura inochinja kakawanda uye nzvimbo dzine maburi makuru emuviri wedhamu.
Nzira dzekuongorora:
Matekiniki ekuyedza asingaparadze anogona kushandiswa, akadai senzira yekuyedza spark. Munzira iyi, voltage yakati inoiswa pamusoro pegeomembrane. Kana paine kukuvara kwegeomembrane, sparks dzinogadzirwa, kuitira kuti nzvimbo dzakakuvara dzikwanise kuwanikwa nekukurumidza. Pamusoro pezvo, kunewo nzira yekuyedza spark. Nzvimbo yakavharwa inoumbwa pakati pegeomembrane nemudziyo wekuyedza, uye kuvapo kwekubuda kwemvura mugeomembrane kunotongwa nekuona shanduko yedhigirii revacuum.
