Cov ntsia hlau yog cov kav hlau uas xaus rau hauv cov hniav thiab cov lus taw qhia. Lawv raug ntsia hlau rau hauv av zoo li cov ntsia hlau.
Ib feem tseem ceeb ntawm pawg yog lub taub, vim nws ua tau ntau yam haujlwm ib zaug:
- yog ib feem ntawm pawg;
- hloov thauj mus rau hauv av;
- tiv thaiv pawg tsis raug yuam tawm hauv av khov thaum lub caij ntuj no hnyav.
Qhov teeb meem los ntawm qhov kawg taw tes yog feem ntau ntsib hauv kev tsim kho ntawm lub teeb ntoo, siv pawg ntawm qhov ntev ntev. Tib txoj hauv kev kom tsis txhob o ntawm cov av yog kom tob hauv lub hauv paus ntawm lub tsev hauv qab kab Frost hauv cheeb tsam kev tsim kho.
Cov ntsia hlau siv nyob qhov twg?
Prefabricated pheej yig lub hauv paus rau lub teeb thav duab lub tsev - qhov no yog qhov twg cov ntsia hlau pawg siv, qhov zoo thiab qhov tsis zoo ntawm peb yuav txiav txim siab me ntsis qis, tab sis tam sim no cia peb txheeb xyuas lawv qhov ntau thiab tsawg.
Nyob hauv tsev twg pawg twg?
Rau tus kheej tsim, cov pawg hauv qab no feem ntau siv: CB89x250, CB108x300, CB133x350. Cov ntawv luv no yog deciphered raws li cov ntsia hlau pawg nrog ib txoj kab uas hla ntawm 89 (108, 133) thiab helical blade txoj kab uas hla ntawm 250 (300, 350). Yog hais tias peb tab tom tham txog lub teeb laj kab thiab cov vaj tsev me me, ces ib pawg 76 mm yuav ua tau; hais txog verandas, gazebos thiab cib laj kab ncej - 89 hli; txog me me thav duab lossis cav tsev - 108 mm. Thiab thaum kawg, yog tias nws tau npaj los tsim lub tsev ntoo dav lossis txawm tias los ntawm cov npuas npuas, tom qab ntawd rau cov ntaub ntawv no, cov pawg nrog lub cev txoj kab uas hla tsawg kawg yog 133 hli yuav tsum tau.
Zoo li txhua yam khoom siv hauv tsev, cov ntsia hlau piles muaj kev tshuaj xyuas tsis zoo, tab sis lawv tsis raug txiav txim los ntawm qhov tsis tsim nyog lossis tsis ntseeg ntawm lub hauv paus no, tab sis los ntawm kev siv tsis raug. Txhua qhov kev tsim kho yuav tsum tau saib xyuas kev tshaj lij thiab tsawg kawg yog kev sib tham, thiab qhov siab tshaj plaws, suav nrog cov ncauj lus kom ntxaws ntawm txhua tus qauv thiab cov khoom thauj.
Screw piles: pros and cons
Tsim lub hauv paus ntawm cov ntsia hlau pawg muaj ntau yam zoo, xws li:
- lawv nrawm thiab yooj yim rau mount, vim lawv tsis tas yuav tsum tau ua ntej drilling thiab concreting;
- Kev tsav tsheb tau ua tau txhua xyoo;
- lawv yeej tsis ntshai tsam nyuaj, av ntau;
- lawv tau tsim ntau hauv cov chaw tsim khoom, uas txhais tau tias lawv cov nqi qis dua li cov qauv ntawm lub hauv paus;
- lawv tuaj yeem ntsia tau rau hauv thiab tawm dua;
- lawv muaj kev tiv thaiv zoo rau lub caij ntuj noav heaving.
Xav txog cov ntsia hlau pawg, qhov zoo thiab qhov tsis zoo ntawm cov qauv no, nws tsis tuaj yeem hais tias los ntawm ib xyoos rau xyoo lawv tau dhau los ua neeg nyiam. Thiab qee zaum muaj cov xwm txheej uas koj ua tsis tau yam tsis muaj lawv txhua.
Txhua yam uas tau hais txog cov ntsia hlau pawg, xav txog qhov tsis zoo uas lawv tau muab piv rau lawv cov "cov kwv tij": lawv muaj lub neej ua haujlwm luv dua vim muaj kev cuam tshuam rau corrosion nyob rau hauv qhov chaw ntub dej, tshwj xeeb tshaj yog tias lawv cov chaw tsim khoom siv cov ntaub ntawv tsis zoo thiab cov txheej txheem ua.
Feem ntau, kev pab cuam lub neej ntawm pawg nyob ntawm ntau qhov tsis sib xws uas yuav tsum tau ua raws: ntawm cov tuab thiab qib ntawm cov hlau, ntawm qhov kev ua haujlwm zoo li cas cov seam txuas cov ncej rau cov hniav yog ua, ntawm qhov zoo ntawm kev tiv thaiv. corrosion coatings thiab nyob rau hauv cov ntxhia muaj pes tsawg leeg ntawm cov av. Yog tias muaj lub siab xav yuav cov khoom lag luam zoo, nws yog qhov yuav tsum tau ua kom txhua daim ntawv hla tebchaws, daim ntawv pov thawj thiab cov ntaub ntawv lees paub kev coj ua thiab cov txiaj ntsig ntawm txhua qhov kev xeem kom raug.
Nyob ntawm kev ua haujlwm ntawm cov ntsia hlau, qhov zoo thiab qhov tsis zoo yuav tshwm sim rau qhov ntau dua lossis tsawg dua. Piv txwv li, yog tias ib pawg siv los ua ib txoj hauv kev hauv av, ces nws yuav feem ntau yuav tawg thiab xeb, vim hais tias nyob rau hauv qhov kev tshwm sim ntawm ib qho kev tawg nyob rau hauv nruab nrab conductor, tam sim no yuav ntws ncaj qha los ntawm lub cev ntawm cov qauv. Cov ntsia hlau tuaj yeem tau txais kev tshuaj xyuas tsis zoo yog tias lub tsev tsim nyob rau hauv ib lub vojvoog ntawm 50 meters los ntawm cov chaw tsim hluav taws xob lossis lub xov tooj ntawm tes. Nyob rau hauv xws li ib qho chaw, ib tug phenomenon yog pom nyob rau hauv cov av, hu uastray tam sim no, uas accelerates electrochemical corrosion.
Tim cov ntsia hlau pawg
Nyob ntawm cov ntsia hlau twg siv, qhov zoo thiab qhov tsis zoo, kev tshuaj xyuas txog lawv yuav txawv. Muaj 2 ntau yam ntawm lawv: nrog ib tug welded taub thiab nrog ib tug cam khwb cia ib tug (nyob rau hauv cov ntaub ntawv no, pawg yog ib tug-daim qauv). Qhov kev xaiv thib ob yog kim dua, tab sis txhim khu kev qha, vim tias qhov vuam yog qhov yooj yim tshaj plaws ntawm cov khoom.
Yuav luag txhua qhov kev tshuaj xyuas tsis zoo yog xa mus rau pawg welded, vim tias lawv feem ntau yog ua los ntawm cov khoom siv tes ua nrog tsis ua raws li cov qauv thiab GOSTs.
Yuav ua li cas thiaj xaiv pawg zoo?
Koj tuaj yeem siv cov welded yog tias koj xav tau tsim cov qauv me xws li laj kab thiab kev tsim tawm. Hauv lwm qhov xwm txheej, kev nyiam yuav tsum tau muab rau cov cam khwb cia, ua los ntawm cov yeeb nkab galvanized. Kev tiv thaiv corrosion ntawm cov hniav yuav tsis daws qhov teeb meem, vim hais tias thaum lub sij hawm screwing nyob rau hauv kev sib txhuam yog siab heev uas tag nrho cov coatings yog yooj yim rubbed.
Yuav kom tsis txhob poob siab ntawm cov ntsia hlau, koj yuav tsum yuav lawv los ntawm cov neeg muag khoom ntseeg siab uas nws qhov zoo koj paub tseeb.
