Hauv qab no, peb pab pawg engineering qhia 7 cov lus qhia kev txhim kho rau kev txhim kho 3D weld mesh fencing rau hauv av tsis sib xws, ua kom muaj kev ncaj ncees thiab pom kev sib xws.
1. Ua Kev Tshawb Fawb Txog Kev Tshawb Fawb
Ua ntej txhua qhov kev khawb, kos cov kab nqes ntawm txoj kab nqes thiab qhov siab hloov pauv hla txoj kab laj kab. Siv lub laser theem lossis theodolite los txheeb xyuas cov ntsiab lus siab, cov ntsiab lus qis, thiab qhov siab tshaj plaws ntsug sib txawv ntawm ib kab meter. Muab faib ua 3 pawg:
Maj mam nqes hav(Tsawg dua los yog sib npaug li 5 degree): Standard posts thiab panels yuav racked me ntsis.
Txoj kab nqes nruab nrab(5℃-15 degree): Yuav tsum tau kauj ruam lossis telescopic post txoj kev.
Txoj kev nqes hav (>15 degree): Kev cai vaj huam sib luag tapering lossis terracing yog tsim nyog.
Kev sau cov ntaub ntawv cov ntsiab lus no ua kom koj xaj qhov raug xa mus ntev thiab kev teeb tsa vaj huam sib luag los ntawm Pauleen qhov kev pabcuam tsim khoom.
2. Xaiv Txoj Cai Post Foundation System rau txhua hom kab nqes
Nyob rau hauv qhov tsis sib xws, post footing yog lub thauj tog rau nkoj ntawm tag nrho lub laj kab. Zam ib qho -size- haum- tag nrho cov qhob ncuav.
Rau qhov chaw nce toj:Siv cov pob zeb sib sib zog nqus (qhov tsawg kawg yog 600 hli qhov tob rau 1.8 m siab laj kab) nrog rau cov rebar reinforcement los tiv thaiv lateral av thrust.
Rau downhill seem:Tsim cov pob zeb ua pob zeb los yog siv lub dab tshos nyob ib ncig ntawm tus ncej kom them nyiaj rau qhov sib txawv qhov siab.
Rau cov pob zeb lossis qhov tob- av nqes hav:Hloov mus rau cov ncej uas tau tsav los yog hauv av screws nrog galvanized brackets, uas txo cov excavation ntim thiab muab kev thauj khoom tam sim ntawd.
Ib txwm tso cai rau lub sijhawm 48-teev kho rau cov pob zeb ua ntej tensioning lub mesh panels.
3. Ua ib kauj ruam txhim kho rau nruab nrab mus rau qhov chaw siab
Txoj kev stepped yog qhov txhim khu kev qha tshaj plaws rau qhov chaw siab tshaj 10 degree. Es tsis txhob ua raws li hauv av contour, ua kom txhua lub laj kab vaj huam sib luag theem, thiab nqis nqis vertically ntawm txhua tus ncej.
Standard kauj ruam poob:100 hli mus rau 200 hli rau ib lub vaj huam sib luag (nyob ntawm qhov siab ntawm vaj huam sib luag).
Kev tiv thaiv overlap:Thaum nce qib, lub vaj huam sib luag qis yuav tsum txuas mus tom qab lub vaj huam sib luag sab sauv tsawg kawg yog 50 mm txhawm rau tiv thaiv qhov khoob.
Post qhov siab hloov:Siv cov ncej ntev (piv txwv li, 2.4 m es tsis txhob 2.1 m) ntawm cov kauj ruam, embed qhov ntev ntxiv rau hauv qab taw kom tswj tau zoo ib yam saum toj no - av raug.
Pauleen's modular 3D panels tuaj yeem ua lub Hoobkas - ua ntej - txiav nrog cov kauj ruam kawg raws li qhov kev thov, tshem tawm ntawm - qhov chaw txiav pov tseg.
4. Siv Racking (Hinged Vaj Huam Sib Luag) kom maj mam, txuas mus ntxiv
Rau txoj kab nqes Tsawg dua lossis sib npaug li 8 degree, racking tso cai rau lub vaj huam sib luag mesh pivot txheeb ze rau cov ncej yam tsis muaj kauj ruam. Txoj kev no khaws cov kab kab rov tav huv ntawm 3D laj kab.
Yuav ua li cas rack:Loosen U-clamps lossis bolt txuas ntawm tus ncej. Tilt lub vaj huam sib luag kom phim txoj kab nqes hauv av. Lub vaj huam sib luag kab pheeb ces kaum deformation (nyob rau hauv 5-8% ntawm nws qhov dav) yog absorbed los ntawm weld mesh lub inherent ductility.
Fixation sequence:Khaws lub vaj huam sib luag rau hauv qab ua ntej, tom qab ntawd nruj nreem clamps. Siv ob -sab compression washers los tiv thaiv kev ntxhov siab ntawm cov welded nodes.
Kev txwv:Tsis txhob rack lub vaj huam sib luag 3D tshaj 10% ntawm nws qhov dav - qhov no ua rau weld point tawg. Rau steeper gradients, kauj ruam xwb.
5. Ua haujlwm Telescopic lossis Adjustable Posts rau Variable Fill Heights
Ib qho ntawm Pauleen qhov kev tsim kho tshiab ntawm engineering yog telescopic 3D laj kab ncej, uas muaj lub tes tsho sab nrauv galvanized thiab ib qho zawv zawg sab hauv.
Daim ntawv thov:Qhov zoo tshaj plaws rau undulating av qhov sib txawv ntawm av thiab vaj huam sib luag hauv qab fluctuates ntawm 50 mm thiab 250 mm.
Kev teeb tsa:Tsav lub tes tsho sab nraud mus rau hauv ib qho kev sib tw ua pob zeb. Tom qab mounting lub panels, xaub lub puab bracket nce los yog down kom ua raws nraim li cov struts, ces xauv nws nrog anti- plam bolts.
Cov txiaj ntsig:Tshem tawm qhov xav tau rau kev cai infill strips los yog unsightly gaps uas tsiaj los yog khib nyiab tuaj yeem nkag mus.
6. Ua ke ib lub pob zeb sau los yog phab ntsa tuav ntawm cov ntsiab lus qis
Nyob rau hauv qhov chaw concave (dip los yog swales), dej pas dej ua ke thiab av yaig nyob rau hauv lub laj kab tuaj yeem ua rau muaj kev ruaj ntseg tom qab. Txo qhov no los ntawm:
Excavating ib tug 300 mm dav, 200 mm sib sib zog nqus trench raws lub qis ntu.
Sau nws nrog angular crushed pob zeb (20-40 mm qib) mus txog rau lub vaj huam sib luag hauv qab ntug. Qhov no ua raws li Fabkis txoj dej ntws thiab tiv thaiv kev loj hlob ntawm cov nroj tsuag.
Rau qhov tob tob tshaj 300 hli, nruab ib lub phab ntsa uas tsis tshua muaj masonry tuav (100 hli tuab) qab lub laj kab kab kom redirect runoff thiab stabilize cov ntaub ntawv sau.
Tsis txhob cia lub mesh vaj huam sib luag tiv tauj av los yog dej sawv ntsug -qhov no ua rau cov txheej txheem degradation txawm tias HDG + hmoov txheej.
7. Validate Post Verticality thiab Vaj Huam Sib Luag Tension nrog Digital Inclinometer
Tom qab ua tiav txhua ntu 20 m ntawm qhov tsis sib xws, ua qhov kev kuaj xyuas zoo:
Post plumbness:Ntsuas ob sab thiab longitudinal qaij. Qhov siab tshaj qhov sib txawv: ± 2℃ib 2 m qhov siab.
Vaj huam sib luag alignment:Khiav ib tug taut kab ntawm thawj mus rau lub xeem ncej. Sab saum toj rail ntawm 3D vaj huam sib luag yuav tsum tsis txhob deviate ntau tshaj 10 hli los ntawm kab no tshaj 10 m ncua.
Mesh tension:Coj mus rhaub lub chaw nruab nrab ntawm lub vaj huam sib luag- ib qho npub rattle qhia tias muaj kev sib txuas xoob. Re-torque tag nrho cov clamps rau 25–30 Nm siv lub ntsuas phoo.
Rau kev txhim kho cov kauj ruam, xyuas kom meej tias qhov sib tshooj ntsug ntawm cov vaj huam sib luag nyob ib sab yog zoo ib yam (feem ntau 50-100 mm) thiab tsis muaj cov npoo ntse.
