I-Geotextile isetshenziswa kakhulu ukufaka esikhundleni sezinto zendabuko eziyimbudumbudu ukuze kwakhiwe isihlungi esihlanekezelwe kanye nomzimba wokudonsa amanzi. Uma kuqhathaniswa nesihlungi sendabuko esihlanekezelwe kanye nomzimba wokudonsa amanzi, unezici zesisindo esilula, ukuqhubeka okuhle konke, ukwakhiwa okulula, amandla aqinile aqinile, ukumelana nokugqwala, ukumelana okuhle nokuguguleka kwe-microbial, ukuthungwa okuthambile, ukuhlangana okuhle nezinto zomhlabathi, ukuqina okuphezulu kanye nesimo sezulu. ukumelana ngaphansi kwamanzi noma enhlabathini, kanye nomphumela ophawulekayo wokusetshenziswa Futhi i-geotextile iphinde ihlangabezane nezimo zezinto zokuhlunga ezihlanekezelwe jikelele: 1 Ukongiwa komhlabathi: vimbela ukulahleka kwempahla yomhlabathi evikelwe, kubangele I-seepage deformation, 2 Ukungena kwamanzi: qinisekisa ukugeleza okushelelayo kwamanzi agelezayo, 3 Impahla evimbelayo: qinisekisa ukuthi ngeke ivinjwe yizinhlayiya zenhlabathi ecolekile.

I-geotextile izonikezwa isitifiketi sekhwalithi yomkhiqizo lapho isetshenziswa, futhi izinkomba ezibonakalayo zizohlolwa: ubukhulu beyunithi ngayinye, ukujiya, indawo yokuvula elinganayo, njll Izinkomba zemishini: amandla aqinile, amandla okudabula, amandla okubamba, amandla okuqhuma, ukuqhuma. amandla, amandla okungqubuzana kokusebenza kwenhlabathi okubalulekile, njll Izinkomba ze-hydraulic: i-permeability coefficient, i-plane permeability coefficient, i-gradient ratio, njll. Ukuqina: ukumelana nokuguga, ukumelana nokugqwala kwamakhemikhali Ukuhlolwa kuzokwenziwa umnyango wokuhlola ikhwalithi yobuchwepheshe oqeqeshiwe. Ngesikhathi sokuhlolwa, izinto zokuhlola ezifanele zingangezwa noma zisuswe ngokuya ngezidingo zephrojekthi kanye nezidingo ezithile zokwakha, futhi kuzokhishwa umbiko wokuhlola onemininingwane.
Ngesikhathi sokubekwa kwe-geotextile, indawo yokuxhumana kufanele igcinwe isicaba ngaphandle kokungalingani okusobala, amadwala, izimpande zesihlahla noma enye imfucumfucu engalimaza i-geotextile Lapho ubeka i-geotextile, akufanele iqine kakhulu ukuze ugweme ukuguquguquka ngokweqile nokuklebhuka kwe-geotextile ngesikhathi. ukwakhiwa. Ngakho-ke, kuyadingeka ukugcina izinga elithile lokuqina. Uma kunesidingo, i-geotextile ingenza i-geotextile ibe nokugoqa okufanayo Uma ubeka i-geotextile: qala ubeke i-geotextile ukusuka phezulu kwesigaba sokugoqa siye phansi, bese usibeka ibhulokhi ngebhulokhi ngokwenombolo. Ububanzi obugqagqene phakathi kwamabhulokhi buyi-1m. Lapho ubeka ikhanda eliyindilinga, ngenxa yobubanzi obuphezulu obuncane futhi obuphansi, ukunakwa okukhethekile kufanele kukhokhwe ekubekweni, ukwakhiwa ngokucophelela kuzokwenziwa, futhi ububanzi obudlulayo phakathi kwamabhulokhi buzoqinisekiswa Ukuhlangana phakathi kwe-geotextile nesisekelo sedamu kanye nebhange. kumele iphathwe kahle Lapho sibeka, kufanele sigcine ukuqhubeka futhi singaphuthelwa ukubeka Ngemva kokubekwa kwe-geotextile, ayikwazi ukuchayeka elangeni ngoba i-geotextile yenziwe ngezinto zokusetshenziswa zamakhemikhali zefiber. Ukuchayeka elangeni kuzolimaza amandla, ngakho-ke kufanele kuthathwe izinyathelo zokuzivikela.
Izinyathelo zethu zokuvikela ekwakhiweni kwe-geotextile yilezi: ukumboza i-geotextile egandayiwe ngotshani, okuqinisekisa ukuthi i-geotextile ngeke ibekwe elangeni, futhi idlala indima engcono ekuvikeleni i-geotextile ukuze kwakhiwe amatshe kamuva Ngisho noma ungqimba oluvikelayo lwe-mulch yotshani. yengezwa futhi ukwakhiwa kwamatshe kwenziwa ku-geotextile, i-geotextile izovikelwa ngokucophelela Ngaphezu kwalokho, uhlelo oluhle kakhulu lokwakha luzokhethwa ngendlela yokwakha yamatshe. Indlela yethu yokwakha iwukuthi, ngenxa yezinga eliphezulu lemishini yokwakha, itshe lithuthwa ngamaloli okulahla. Ngesikhathi sokuthululwa kwamatshe, kuqokwa umuntu okhethekile ukuba aqondise imoto ukuze ehlise itshe, futhi itshe lithululwe ngaphandle komgodi wamatshe ezimpande I-tank yokudlulisa imanuwali kufanele iphathwe ngokucophelela ukugwema ukulimaza i-geotextile Okokuqala, gwedla lonke itshe eduze. ngaphansi komsele 0.5m. Ngalesi sikhathi, abantu abaningi bangakwazi ukujikijela amatshe eduze kwetshe lesithiyo ngokucophelela. Ngemva kokuba umsele usugcwele, dlulisa ngokwakho amatshe emthambekeni ongaphakathi wesisekelo sedamu lomhlaba. Ububanzi betshe bufana nalokhu okudingekayo ngokuklama. Itshe liyophakanyiswa ngokulinganayo ngesikhathi sokulahlwa kwamatshe. Ubuso betshe besithiyo eduze komthambeka ongaphakathi akumele bube phezulu kakhulu Uma buphakeme kakhulu, akuphephile ku-filament elukiweyo ye-geotextile, futhi ingase futhi ishelele phansi, ibangele umonakalo ku-geotextile Ngakho-ke, ukunakwa okukhethekile kufanele kukhokhwe. endaweni ephephile lapho kwakhiwa Uma amatshe ayisicaba ebekwa eduze komgodi ongaphakathi wethayi lomhlabathi ukuya ku-2m ukusuka endaweni yedamu, amatshe ayobekwa eceleni kwendawo engaphakathi. umthambeko, futhi ukujiya akufanele kube ngaphansi kuka-0.5m. Amatshe ayothululelwa esiqongweni sedamu, futhi amatshe ayolahlwa ngokucophelela ngesandla, futhi amatshe ayolinganiswa ngenkathi ejikijelwa aze alingane nesiqongo sedamu lomhlaba. kufanele ilinganiswe ukuze kufinyelele ukuthambekela okuphezulu okubushelelezi.
① Isendlalelo esivikelayo: ungqimba olungaphandle kakhulu oluxhumene nomhlaba wangaphandle. Ihlelelwe ukuvikela umthelela wokugeleza kwamanzi angaphandle noma amagagasi, isimo sezulu kanye nokuguguleka, ukuqandisa nokulimaza iringi futhi ivikele imisebe ye-ultraviolet yokukhanya kwelanga. Ugqinsi luvamise ukuba ngu-15-625px.
② Umcamelo ongaphezulu: ungqimba olushintshayo phakathi kongqimba oluvikelayo kanye ne-geomembrane. Njengoba ungqimba oluyisivikelo luyizicucu ezinkulu zezinto ezimahhadla futhi kulula ukuhamba, uma lubekwe ngokuqondile ku-geomembrane, kulula ukulimaza i-geomembrane. Ngakho-ke, i-cushion engenhla kufanele ilungiswe kahle. Ngokujwayelekile, kunento yetshe yesihlabathi, futhi ukujiya akufanele kube ngaphansi kuka-375px.
③ I-Geomembrane: iyindikimba yokuvimbela ukugeleza kwamanzi. Ngokungeziwe ekuvimbeleni okuthembekile kwe-sepage, kufanele futhi ikwazi ukumelana nengcindezi ethile yokwakha kanye nengcindezi ebangelwa ukuhlaliswa kwesakhiwo ngesikhathi sokusetshenziswa. Ngakho-ke, kunezidingo zamandla. Amandla e-geomembrane ahlobene ngokuqondile nokujiya kwayo, okunganqunywa ngokubala kwethiyori noma ulwazi lobunjiniyela.
④ Umcamelo ophansi: obekwe ngaphansi kwe-geomembrane, unemisebenzi emibili: enye iwukukhipha amanzi negesi ngaphansi kolwelwesi ukuze kuqinisekiswe ukuzinza kwe-geomembrane; enye iwukuvikela i-geomembrane ekulimaleni kwesendlalelo esisekelayo.
⑤ Isendlalelo sokusekela: i-geomembrane iyimpahla eguquguqukayo, okumele ibekwe phezu kwesendlalelo esithembekile, esingenza i-geomembrane icindezeleke ngokulinganayo.
