1. Mmepụta ihe owuwu
Netwọk mmiri mmiri nke akụkụ atọ. Ejiri akụkụ abụọ nke geotextile na akụkụ atọ nke geotextile mee isi mesh ahụ. Ejiri polyethylene dị elu (HDPE) mee isi mesh ahụ. Usoro ịkpụzi akụkụ atọ ahụ na-emepụta netwọk ọgịrịga na-agafe agafe, a na-egosipụtakwa ihe pụrụ iche ya n'akụkụ abụọ ndị a:
1, Sistemụ oghere gradient: oghere rịbọn kwụ ọtọ nke isi mesh bụ 10-20 mm, rịbọn elu na rịbọn ala na-emepụta ọwa ntụgharị atọ, nke kwekọrọ na nhazi oghere nke geotextile (oyi akwa elu 200 μm, ọkwa ala 150 μm) , Nha ihe a na-ekewapụ karịrị 0.3 mm nke ihe dị n'ime ya, nzacha "njikọ nzacha dị nro" nke Real Now.
2, Nhazi mgbochi itinye ihe: ọkpụrụkpụ úkwù dị n'etiti mesh ruo 4-8 mm, Na 2000 kPa, enwere ike idobe ihe karịrị 90% nke ọkpụrụkpụ mbụ n'okpuru ibu, ka e wee zere itinye geotextile n'ime mesh n'ihi nrụgide mpaghara. Dịka data injinia nke ebe a na-ekpofu ihe si dị, mgbe afọ ise nke ojiji gasịrị, oyi akwa mmiri mmiri na-eji ihe a ga-eduzi mmiri. Ọnụego mbelata ọnụego bụ naanị 8%, nke dị ala karịa 35% nke oyi akwa gravel ọdịnala.
2. Njirimara ihe onwunwe
1,Nkwụsi Ike Kemịkalụ: HDPE Isi mesh ahụ na-eguzogide mmebi acid na alkali. Na pH N'ime gburugburu acid na-adịghị ike na ntọala adịghị ike nke nwere uru nke 4-10, ọnụego njigide nkwụsi ike nke nhazi molekul ya karịrị 95%. Polyester ejikọtara ọnụ Filament geotextile Mkpuchi na-eguzogide UV nwere ike iguzogide ịka nká nke radieshon UV kpatara.
2, Usoro nhicha onwe onye: oke ike nke isi mesh Ra Value nke a na-achịkwa na 3.2-6.3 μm N'ime oke ahụ, ọ bụghị naanị na ọ nwere ike ijide n'aka na mmiri na-agbapụta nke ọma, kamakwa ọ nwere ike izere njikọta biofilm nke oke ire ụtọ kpatara.
3. Ọrụ injinia
1, Ngwa maka itinye ihe mkpofu: N'ime ebe a na-ekpofu ihe mkpofu nke nwere ikike nhazi kwa ụbọchị nke tọn 2,000, netwọk mmiri mmiri mejupụtara akụkụ atọ na HDPE. Akpụkpọ ahụ mejupụtara usoro mgbochi mmiri. Isi ya dị n'akụkụ atọ nwere ike iguzogide 1500 kwa ụbọchị m³ Ibu mmetụta nke mmiri mkpofu, yana ọrụ azụ nke geotextile, nwere ike iru oghere. A na-ewepụ mmiri mmiri ahụ n'otu ụzọ, nke nwere ike igbochi mmiri ozuzo ịlaghachi azụ. Mgbe afọ 3 nke ọrụ gasịrị, uru mbelata nrụgide nke laminate mmiri drainage bụ naanị 0.05 MPa, Ọ dị ala karịa oke imewe nke 0.2 MPa.
2, Ngwa injinia okporo ụzọ: N'okporo ụzọ dị n'ala kpọnwụrụ akpọnwụ na ugwu China, enwere ike iji ya dị ka oyi akwa mmiri mmiri dị n'okpuru ala, nke nwere ike ibelata ọkwa mmiri ala site na 1.2% site na igbochi mmụba nke mmiri capillary m. Nkwụsi ike nke isi mesh ya bụ 120 kN/m², Ọ nwere ike igbochi mbugharị nke oyi akwa ntọala mkpokọta ma belata ihe mgbawa na-egosipụta. Nleba anya na-egosi na ọnụọgụ nke ngalaba okporo ụzọ na-eji teknụzụ a belatara site na 67% ma e jiri ya tụnyere ọrịa ndị dị n'okpuru ala ọdịnala, a na-agbatịkwa ndụ ọrụ ruo ihe karịrị afọ 20.
3, Ngwa injinia Ọwara: N'ime ọwara ụgbọ okporo ígwè na-agafe na stratum bara ụba na mmiri, a na-eji netwọk mmiri mmiri mejupụtara akụkụ atọ na ákwà mgbochi grouting ọnụ iji mepụta usoro mmiri na-adịghị egbochi mmiri nke "ịjikọta mmiri mmiri na igbochi". Isi ya nwere ike ịrụ ọrụ nke hydraulic nke 2.5 × 10⁻³m/s, Efere mmiri mmiri ọdịnala ndị ọzọ na-eme ka ọ dịkwuo mma ugboro atọ, soro ndị na-arụ ọrụ na geotechnical Ákwà. Ọrụ nzacha nwere ike ibelata ihe egwu nke mkpọchi nke usoro mmiri mmiri ọwara site na 90%.
4. Atụmatụ mmezi
1, Nlekota Ịntanetị nke Ihe: A na-etinye ihe mmetụta eriri anya na netwọk mmiri iji nyochaa paramita dịka njikwa hydraulic, nrụgide na nrụgide n'oge.
2. Mmiri na-agbaze n'elu mmiri: ebe ndị a kpọchiri akpọchi, jiri 20-30 MPa. Mmiri na-agbaze n'elu mmiri maka ịkwọgharị n'ụzọ. Ọdịdị ọgịrịga nke isi mesh nwere ike ibuli nrụgide ahụ na-enweghị mgbanwe, ọnụego mgbake nke hydraulic conductivity mgbe ọ gbasịrị ya karịrị 95%.
