Ese urusobe rw'amazi rugizwe n'ibice bitatu rushobora gukumira gufunga no kubura amazi?

Mu buhanga, ikibazo cyo gukurura ivumbi cyahoraga ari ingenzi cyane. Urusobe rw'amazi rugizwe n'ibice bitatu. Ni ibikoresho bikoreshwa cyane mu mishinga minini. None se, bishobora gukumira gukurura ivumbi no kuziba?

1. Udushya mu miterere y'inyubako

Urusobe rw'amazi rugizwe n'imirongo ibiri ya geotextile n'imirongo itatu ya geotextile. Imirongo igizwe na polyethylene ifite ubucucike bwinshi (HDPE) Uburyo bwo gushushanya imirongo itatu bukora urusobe rw'imirongo ihuza imbavu, kandi umwihariko wayo ugaragarira mu ngingo ebyiri zikurikira:

1. Sisitemu y'imirongo y'ubugari: hagati y'imbavu zihagaze z'inyuma y'urushundura ni mm 10-20, Imbavu zo hejuru n'imbavu zo hasi bikora umuyoboro wo kuzenguruka ufite imiterere itatu, uhuye n'imiterere y'ubugari bw'ubugari bwa geotextile (urwego rwo hejuru 200 μm, urwego rwo hasi 150 μm）， Ingano y'uduce dushobora kwakirwa irenga mm 0.3 z'uduce, Real Now "iyungurura ry'ubugari rito" ryagenwe ku ruhushya.

2. Igishushanyo mbonera cyo kwirinda gukurura: ubugari bw'imbavu z'umuyoboro w'amazi kugeza kuri mm 4-8, Muri kPa ya 2000. Ubunini burenga 90% by'ubunini bw'umwimerere buracyashobora kugumana umutwaro, kugira ngo hirindwe ko umuyoboro w'amazi winjizwa mu muyoboro bitewe n'aho ucucitse. Dukurikije amakuru y'ubuhanga y'aho imyanda ijugunywa, nyuma y'imyaka 5 ikoreshwa, urwego rw'amazi rukoresha iki gikoresho ruzatwara amazi. Igipimo cyo kugabanya umuvuduko ni 8% gusa, kiri hasi cyane ugereranyije na 35% by'urwego rw'amabuye rusanzwe.

2. Imiterere y'ibikoresho

1. Gukomera mu bya shimi: HDPE. Ishingiro ry'urushundura rirarwanya aside na alkali. Muri pH. Mu butaka bufite aside nke n'ibanze budakomeye bufite agaciro ka 4-10, imiterere ya molekile irahinduka cyane. Igipimo cyo kugumana imiterere ya molekile kirenga 95%. Polyester ivanze. Ifu ya geotextile irwanya UV ishobora kurwanya gusaza kw'ibintu biterwa n'imirasire ya UV.

2. Uburyo bwo kwisukura: ubukana bw'ubuso bw'inkingi ya mesh Ra. Agaciro kagenzurwa kuri 3.2-6.3 μm. Mu rwego rwo kugabanya ubukana bw'amazi, ntabwo bushobora gusa kwemeza ko amazi akoreshwa neza, ahubwo bunarinda gufatana kwa biofilm bitewe no koroha cyane.

3. Imyitozo y'ubwubatsi

1. Gukoresha imyanda: Mu myanda ifite ubushobozi bwo gutunganya toni 2.000 ku munsi, urusobe rw'amazi rugizwe n'ibice bitatu na HDPE. Urusobe rw'amazi rugizwe n'uburyo butuma amazi adasohoka. Urufatiro rwayo rugizwe n'ibice bitatu rushobora kwihanganira 1500 ku munsi m³Umutwaro w'amazi asohoka, hamwe n'imikorere ya geotextile, bishobora gutuma amazi asohoka mu cyerekezo kimwe, bigatuma amazi adasubira inyuma. Nyuma y'imyaka 3 ikora, igipimo cyo kugabanuka k'umuvuduko wa laminate y'amazi ni 0.05 MPa gusa, munsi y'ikigereranyo ntarengwa cya 0.2 MPa.

2. Ikoreshwa ry'ubuhanga mu mihanda: Mu muhanda munini mu gace k'ubutaka bukonje mu majyaruguru y'Ubushinwa, ushobora gukoreshwa nk'urwego rw'amazi yo munsi y'ubutaka, bishobora kugabanya urugero rw'amazi yo munsi y'ubutaka ho 1.2% binyuze mu kubuza amazi yo mu miyoboro y'amazi kwiyongera m. Ubukana bw'inyuma bw'inkingi yayo y'amazi ni 120 kN/m, Ishobora kugabanya kwimuka kw'urwego rw'ibanze rw'ubutaka no kugabanya icyuho cyo kugarura urumuri. Igenzura ryerekana ko ikwirakwira ry'ibice by'umuhanda ukoresha iri koranabuhanga rigabanukaho 67% ugereranije n'indwara zisanzwe zo munsi y'ubutaka, kandi igihe cyo kuyikoresha cyongerwaho imyaka irenga 20.

3. Gukoresha ikoranabuhanga rya Tunnel: Mu muyoboro wa gari ya moshi unyura mu gice cy’amazi menshi, urusobe rw’amazi rugizwe n’ibice bitatu n’umushumi w’amazi bikoreshwa hamwe kugira ngo habeho uburyo budashobora kuvogerwa n’amazi bwo “guhuza amazi no kuyafunga”. Imbere yayo ifite uburyo bwo gutwara amazi bwa 2.5 × 10⁻³m/s, Isahani isanzwe yo gusohora amazi. Kongera imbaraga inshuro 3, korana n’igitambaro cya geotechnical. Imikorere yo kuyungurura ishobora kugabanya ibyago byo kuziba imiyoboro y’amazi ku kigero cya 90%.

4. Ingamba zo kubungabunga

1, Gukurikirana ibintu kuri interineti: Ibikoresho by'ikoranabuhanga bya fibre optique bishyirwa mu muyoboro w'amazi kugira ngo bigenzure ibipimo nko kuyobora amazi mu kirere, umuvuduko w'amazi n'imbaraga mu gihe nyacyo.

2. Gutunganya amazi akoresha umuvuduko mwinshi: ahantu hafunze, koresha 20-30 MPa. Umuvuduko mwinshi w'amazi ukoresha umuvuduko mwinshi mu gukurura icyerekezo. Imiterere y'imbavu z'inkingi y'umuyoboro w'amazi ishobora kwihanganira umuvuduko nta guhindagurika, kandi igipimo cyo kugarura umuvuduko w'amazi nyuma yo gucukura kiri hejuru ya 95%.
