Hnyav plaub ntug Gabion Box rau Erosion Control
A hnyav luag hauj lwm gabion boxyog ob npaug -twisted hexagonal hlau pob tawb uas muaj cov pob zeb ntuj, ua nrog cov hlau tuab dua li cov pob tawb txheem rau qhov chaw uas cov dej ntws tawm tsam. Qhov twg tswj kev yaig zoo ib yam tsis ua tiav - cov ntug dej ntws los ntawm cov dej ntws, qhov chaw siab tshaj los ntawm kev ua yoj, cov dej ntws nrawm nrawm - cov mesh hnyav dua thiab cov qauv lub thawv muaj zog tuav lub pob zeb ntim rau hauv qhov chaw thiab ua haujlwm txawm tias cov av hauv qab nyob. Nplooj ntawv no piav qhia seb qhov hnyav ntawm cov hlau yuav xaiv thiab qhov twg lub thawv hnyav yog nyob rau hauv kev tswj kev yaig.
Khoom Specification
Vim li cas Erosion Sites xav tau lub thawv hnyav dua
Kev tswj kev yaig ua tsis tau raws li qhov sib txawv ntawm kev tuav cov phab ntsa. Ib phab ntsa tuav thawb tawm tsam lub ntiaj teb; ib tug erosion qauv tau txaisrub sib nrug los ntawm dej- scour undercuts tus ntiv taw, ntws snatches pob zeb los ntawm lub mesh, thiab dej khov los yog khib nyiab snags cov xov hlau. Peb lub zog ua rau lub luag haujlwm hnyav gabion lub thawv yog cov lus teb rau cov chaw:
Thicker, muaj zog hlau- 3.0–4.0mm hlau tiv thaiv kev puas tsuaj los ntawm cov av khib nyiab hauv cov dej nrawm thiab muaj sia nyob cuam tshuam los ntawm cov khib nyiab, zoo dua li 2.2-2.7mm txheem mesh
Flexibility yam tsis ua tsis tiav- thaum scour tshem tawm cov av hauv qab ntiv taw, lub thawv gabion nyob thiab deforms ntau dua li tawg; rigid pob zeb revetments poob lub sij hawm lawv lub hauv paus yog undermined
Diaphragms tuav lub thawv zoo li- cov kev faib sab hauv nres cov pob zeb tsiv teb tsaws raws lub pob tawb, yog li cov ntawv sau nyob twj ywm sib npaug thiab cov qauv khaws nws cov qauv tsim los ntawm dej nyab
Gabion Box vs Riprap vs Qhob rau Erosion Sites
| Kev daws | Txom nyem | Zaub | Kev teeb tsa | Pob zeb siv |
|---|---|---|---|---|
| Heavy duty gabion box | Settles, nyob twj ywm | Loj hlob los ntawm mesh | Prefabricated, ceev ceev | Ordinary pob zeb ok |
| Loos riprap | Rolls tseg, xav tau kev rov ua haujlwm dua | Tsis muaj | Cov tshuab hnyav, tuab txheej | Loj graded pob zeb |
| Qhob revetment | Cracks thaum undermined | Tsis muaj | Formwork, kho lub sijhawm | Tsis siv tau |
Cov txheej txheem yaig yooj yim zoo li lub thawv gabion zam qhov sib txawv ntawm qhov sib txawv uas yuav tawg cov pob zeb tsis sib xws, thaum lub woven mesh khaws cov pob zeb uas muaj nyob rau hauv ib txoj kev xoob riprap tsis tuaj yeem - tsis muaj dov, tsis ntxuav tawm, tsis muaj rework tom qab txhua lub caij dej nyab.
Hlau Weight xaiv rau Erosion Duty
| Hlau Dia | Daim ntawv thov Erosion | Flow / Tshaj tawm |
|---|---|---|
| 3.0mm (hnyav) | Kev tiv thaiv Riverbank, txoj kab nqes paving, cov kav dej | Tsis tu ncua mus rau ~ 4m / s |
| 3.5mm (hnyav ntxiv) | Torrent Rivers, weirs, choj abutment scour tiv thaiv | Ceev ceev mus ~ 5-6m / s |
| 4.0mm (siab tshaj) | ntug hiav txwv embankments, outfall structures, khib nyiab- torrents | Wave action, abrasive sediment |
Txheem ob -twisted hexagonal mesh yog 8 × 10cm (xaim ntug 6 × 8cm muaj). Rau cov chaw ntug dej hiav txwv thiab ntsev, qhia Galfan (Zn-5%Al) lossis PVC-coated hlau - cov txheej yog dab tsi muaj sia nyob ntsev tsuag, tsis yog cov zinc txheej. Standard box compartments: 2 × 1 × 1m thiab 3 × 1 × 1m nrog sab hauv diaphragms txhua meter, kev cai qhov ntev muaj.
Box los yog txaj? Sib piv cov khoom rau lub xaib
Cov neeg yuav khoom feem ntau tsis meej pem txog ob yam khoom yaig. Txoj cai ntawm tus ntiv tes xoo:cov thawv tiv thaiv cov nqes hav thiab cov tsev txhab nyiaj, cov ntaub pua tsev tiv thaiv cov txaj tiaj tus. Ntawm tus dej uas muaj ob qho teeb meem, lawv tau siv ua ke - txaj rau ntawm lub txaj channel, cov thawv nce mus rau lub txhab nyiaj.
Heavy duty gabion box(nplooj no) - 1m siab rau kev tiv thaiv tsev txhab nyiaj, khaws cia thiab cov chaw ntug dej hiav txwv qhov chaw uas nplawm tawm tsam tus ntiv taw
Gabion txaj- qis-profile 0.3–0.5m units rau channel txaj, culvert aprons thiab spillways qhov twg cov qauv nyob tiaj tus hauv qab dej ntws
Xa peb qhov chaw kos duab lossis hla - ntu nrog cov dej ntws thiab peb yuav pom zoo cov txheej txheem - lub thawv, txaj, lossis ib qho kev sib koom ua ke - nrog rau daim nqi ntawm cov ntaub ntawv thiab lub Hoobkas- nqe lus ncaj qha hauv 24 teev.
