Core Technology: "Kev Tshawb Fawb thiab Kev Kho Mob" Mechanism ntawm Microbial Capsules
Lub plawv ntawm cov khoom ntse no nyob hauv nws "pre-embedded biological repair system." Cov pab pawg kws tshaj lij encapsulate tshwj xeeb acclimated Bacillus subtilis thiab calcium lactate as-ham nyob rau hauv biodegradable sodium alginate capsules (2-3mm inch), ces sib tov rau hauv pob zeb nrog 20-50mmcobblestoneaggregates ntawm 3% ntim piv. Cobblestones, raws li ntuj tsim siab - lub zog aggregates (compressive zog Ntau dua los yog sib npaug rau 120MPa), muab cov pob zeb ua cov cuab yeej siv yooj yim; microbial capsules, zoo li "cov tub rog kho dormant," faib sib npaug ntawm qhov sib txawv.
Thaum cov pob zeb tsim cov kab nrib pleb (dav Tsawg dua lossis sib npaug li 0.5 hli) vim qhov hloov pauv lossis qhov kub thiab txias, dej nag lossis dej tu nkag mus rau hauv cov kab nrib pleb thiab ua rau cov tshuaj capsule degradation, tso Bacillus subtilis thiab calcium lactate. Nrog cov dej noo thiab oxygen, cov kab mob sai sai tsim thiab metabolize los tsim cov calcium carbonate (calcite), tsim cov crystalline filling txheej hauv qhov tawg hauv 3-7 hnub. Cov khoom siv biomineralized no, nrog lub zog compressive ntawm 35MPa, sib tw lub zog ntawm niam txiv pob zeb, ua tiav "autonomous tawg kaw." Lab cov ntaub ntawv qhia tias lub kaw lus ua tiav 100% kho tus nqi rau micro-kawg (0.1-0.3mm dav) thiab tshaj 90% rau 0.3-0.5mm tawg.
Engineering Validation: Qingdao Hla-Hiav Txwv Choj's "Tus Kheej- Kho" Xyaum
Txoj haujlwm kho ntawm Qingdao Jiaozhou Bay Cross-Hiav Txwv Choj tau cim thawj qhov loj - nplai daim ntawv thov ntawm cov thev naus laus zis no. Qhov 36.48km hla- hiav txwv txoj haujlwm no, nrog rau cov ntu ua vaj tse, tsim 237 qhov tawg pom tom qab 10 xyoo kev pabcuam vim dej hiav txwv yaig thiab tsheb thauj khoom, xav tau ntau dua 20 lab yuan ib xyoos rau kev kho phau ntawv. Hauv xyoo 2022, nws txoj kev txuas txuas txuas txuas tau kho dua tshiab siv tus kheej{10}} kho pob zeb pob zeb, npog 12,000㎡.
Tom qab- kho dua tshiab saib xyuas cov ntaub ntawv qhia tau hais tias: tom qab 2 xyoos ntawm kev ntsuas dej ntws thiab ntsuas kub, qhov kho dua tshiab tau tsim tsuas yog 19 qhov tawg tshiab, 17 ntawm qhov uas (89%) tus kheej- kho tau hauv ib hlis, ua tiav qhov kev kho qhov tawg tag nrho ntawm 92%. Kev ntsuam xyuas cov kabmob muaj peev xwm qhia tau hais tias cov pob zeb kho qhov elastic modulus rov qab mus rau 95% ntawm nws lub xeev qub, deb tshaj li 80% rov qab los ntawm cov khoom siv kho ib txwm. Raws li cov qauv no, tus choj seem lub neej yog kwv yees los ntawm qhov tsim los ntawm 50 xyoo mus rau 100 xyoo, tsis tas yuav tsum muaj kev kho loj - teev kev kho ntawm nws lub neej.
Tus nqi sib piv: Kev hloov pauv nyiaj txiag los ntawm tag nrho -Lifecycle Perspective
Txawm hais tias nws tus kheej- kho pob zeb pob zeb raug nqi 15% ntau dua li cov pob zeb pob zeb zoo tib yam (kwv yees li ¥ 480 / m³ vs ¥ 417 / m³), nws tag nrho - tus nqi ntawm lub neej yog qhov tseem ceeb. Noj Qingdao Hla-Hiav Txwv Choj ua piv txwv, cov khoom ua vaj tse ib txwm xav tau loj- kho qhov tawg txhua txhua 10 xyoo, nrog rau cov nqi txij nkawm mus txog ¥600/㎡; nrog rau tus kheej- cov ntaub ntawv kho mob, tsuas yog 3 qhov kev ua haujlwm yooj yim uas xav tau tshaj 100 xyoo, txo tus nqi kho rau ¥ 240/㎡- txo qis 60%.
Rau cov haujlwm tshiab, kev lag luam tseem ceeb dua: 10,000-tuj chaw nres nkoj dam siv cov khoom no nce nqi kev tsim kho pib los ntawm kwv yees li 800,000 ¥ tab sis txuag tau tshaj ¥ 5 lab hauv kev saib xyuas tus nqi los ntawm kev txo 8 qhov kev kho dua tshiab. Tam sim no, thev naus laus zis tau suav nrog hauvCov Lus Qhia rau Kev Siv Cov Khoom Tshiab hauv Kev Loj Hlob Engineeringthiab tau nce qib hauv 12 qhov loj hauv kev tsim kho vaj tse hauv tsev, dhau los ua tus qauv rau kev tsim kho ntse.
