Inhlanganisela ye-net lap yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu

Inethiwekhi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu. Iyinto yokukhipha amanzi evame ukusetshenziswa kwezobunjiniyela futhi ingasetshenziswa ezindaweni zokulahla udoti, emigwaqweni emikhulu, ezitimeleni, emabhulohweni, emathuneni, ezindlini ezingaphansi komhlaba nakwamanye amaphrojekthi. Inesakhiwo esiyingqayizivele esihlanganisiwe sengqimba yegridi enezinhlangothi ezintathu kanye nezinto ze-polymer, ngakho-ke ayigcini nje ngokuba nokusebenza kahle kokukhipha amanzi, kodwa futhi inemisebenzi eminingi efana nokuvikela nokuhlukaniswa. Ubuchwepheshe bayo bokuhlangana kwe-lap bungahlotshaniswa nokuzinza nokusebenza kahle kokukhipha amanzi kulo lonke iphrojekthi.

1. Inethiwekhi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu Izici eziyisisekelo ze

Inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu yakhiwe nge-mesh core enezinhlangothi ezintathu eguquguqukayo kanye ne-polymer geomaterial, futhi ungqimba lwayo oluyinhloko ngokuvamile lwenziwe nge-polyethylene ephezulu (HDPE) Noma i-polypropylene (PP) Yenziwe, inamandla okuthwala umthwalo kanye nokuqina okuhle kakhulu. I-geomaterial emboze ungqimba oluyinhloko ingathuthukisa ukumelana kwayo nokugeleza kwamanzi, futhi ifakwe nepayipi lokudonsa amanzi ukuze ikhiphe ngokushesha uketshezi oluqongelelwe.

2. Ukubaluleka kobuchwepheshe obuhambisanayo

Enkambisweni yokubeka inethiwekhi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu, ubuchwepheshe be-lap joint bubaluleke kakhulu. Ukuhlangana okulungile akugcini nje ngokuqinisekisa ukuqhubeka nobuqotho benethiwekhi yokukhipha amanzi, kodwa futhi kuthuthukisa ukusebenza kahle kokukhipha amanzi kanye nokuzinza kwephrojekthi iyonke. Ukuhlangana okungalungile kungaholela ekuphumeni kwamanzi, ukuvuza kwamanzi kanye nezinye izinkinga, okuzothinta ikhwalithi nokuphepha kwephrojekthi.

3. Izinyathelo ezihambisanayo zenethiwekhi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu

1、Lungisa ukuqondiswa kwezinto: Kuyadingeka ukulungisa ukuqondiswa kwezinto zokwenziwa kwe-geosynthetic ukuqinisekisa ukuthi ubude bomqulu wezinto zokusetshenziswa buhambisana nobude be-geomembrane engangenisi amanzi.

2、Ukuqeda kanye nokweqana: Inethiwekhi yokudonsa amanzi ye-geotechnical ehlanganisiwe kumele iqedwe, futhi i-geotextile enkabeni ye-geonet eseduze kumele ihambisane nemigoqo yensimbi ye-roll yezinto zokwakha eluhlaza. Ama-geonet cores emigoqo ye-geosynthetic eseduze kufanele axhunywe komunye nomunye ngamabhakede epulasitiki afana nobisi noma amabhande e-polymer, futhi amabhande kufanele axhunywe izikhathi eziningana njalo ngamasentimitha angu-30 ukuze kuthuthukiswe ukuzinza kokuxhumana.

3、Ukwelashwa nge-geotextile yezinsimbi ezigoqene: Ukuqondiswa kwe-geotextile yezinsimbi ezigoqene kufanele kufane nokuqondiswa kokuqongelela kokugcwalisa. Uma kubekwe phakathi kwe-subgrade noma i-sub-base, kufanele kwenziwe ukushisela okuqhubekayo, ukushisela ikhanda eliyindilinga noma ukwelashwa kokuthunga ukuqinisekisa ukufakwa kwengqimba ephezulu ye-geotextile. Uma kusetshenziswa ama-suture, sebenzisa indlela yokuthunga ikhanda eliyindilinga noma indlela evamile yokuthunga ukuze uhlangabezane nesidingo esincane sobude be-angle yenaliti.

4. Ukuxhumeka kwamanethiwekhi okukhipha amanzi avundlile naqondile: Ngesikhathi senqubo yokubeka, ukuxhumana phakathi kwamanethiwekhi okukhipha amanzi ahlanganisiwe avundlile anezinhlangothi ezintathu kanye namanethiwekhi okukhipha amanzi ahlanganisiwe avundlile anezinhlangothi ezintathu kubaluleke kakhulu. Indawo lapho amanetha amabili okukhipha amanzi axhunywe khona ahlangana ne-Non-woven geotextile. Dabula ububanzi obuthile, usike ingxenye ephakathi ye-mesh core, bese ushisela ukuphela kwe-mesh core ngokushisela okuyisicaba, bese ekugcineni uxhuma ama-geotextile angelukiwe kuzo zombili izinhlangothi zegridi ngokulandelana.

5. Ukugoqa kanye nokugcwalisa ngemuva: Ngemva kokubeka, izindwangu ezingalukiwe ezinhlangothini zombili ezizungeze umongo we-mesh kufanele zithungwe ndawonye ukuze kuvinjelwe ukungcola ukuthi kungangeni umongo we-mesh futhi kuthinte ukusebenza kokukhipha amanzi. Lapho kufakwa emuva, ubukhulu bokugcwalisa ngemuva kwesendlalelo ngasinye akufanele bube ngaphezu kwama-40 cm, Futhi kudinga ukuhlanganiswa ungqimba ngesendlalelo ukuqinisekisa ukuzinza nokusebenza kahle kokukhipha amanzi enethini yokukhipha amanzi.

Kungabonakala kusukela ngenhla ukuthi ubuchwepheshe bokugqagqana kwenethiwekhi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu buyisixhumanisi esiyinhloko sokuqinisekisa ukusebenza kwayo kokudonsa amanzi kanye nokuqina kobunjiniyela. Ngezindlela nezinyathelo ezihambisanayo ezifanele, ukuqhubeka nobuqotho benethiwekhi yokudonsa amanzi kungaqinisekiswa, futhi ukusebenza kahle kokudonsa amanzi kanye nokuphepha kwephrojekthi yonke kungathuthukiswa.
