Waterproofing expansion ob leeg nyob rau hauv underground lug

Underground chaw nres tsheb los yog recessed, raws li zoo raws li lwm yam ntawm no hom yuav raug deformations uas tej zaum yuav tshwm sim thaum sab nraum cua kub hloov mus hloov los, raws li zoo raws li uas tsis yog niaj hnub zoo li nag lossis daus primer. Tau thiab deformation thaum lub sij hawm seismic thiab lwm yam tshwm sim. Nyob rau hauv tus ntawm lub saum toj no yam tej zaum yuav tshwm sim tus kheej txhawj xeeb uas los ua ib tug ua ntawm tej kab nrib pleb hauv kev lug. Lawv txo tus kabmob muaj peev xwm thiab ua rau lub fact tias cov waterproofing txheej loses nws cov ntseeg.

Nyob rau hauv thiaj li yuav tshem tawm thiab tiv thaiv kom txhob no tshwm sim, nyob rau hauv muab thiab txhawb lug underground Siv yuav tsum expansion pob qij txha. Lawv txo tus dabtsi yog khoov txhawj xeeb nyob rau hauv cov ntsiab lus ntawm loj tshaj deformation, Ntxiv, xws phenomena los ntawm lub nqaws yog tsis txaus ntshai.

hais

expansion ob leeg waterproofing yuav tsum tau nqa tawm tom qab lub xaiv ntawm cov technology tej hauj lwm. Vim lub fact tias cov load rau tej designs yog heev xav txog cov transverse thiab longitudinal qhia, expansion pob qij txha nyob rau hauv underground lug yuav tsum sib txawv ntawm cov neeg uas muaj nyob rau hauv lwm qhov chaw ntawm cov vaj tse. Heev feem ntau nws yog tsim nyog los siv ib qho kev mus kom ze uas muab rau ob peb systems, uas ib tug waterproofing txheej teev zoo cia siab rau thiab durability. Niaj hnub no ob peb hom kev kawm paub li xws pob qij txha uas yog nyob rau ntawm ob leeg dav, hom thiab technology waterproofing lug. Ua ntej yuav koom ib qho kev daws yuav tsum paub txog tag nrho cov tau xaiv xam tau tias yog lawv pluses thiab minuses.

Kev siv cov sealants

Waterproofing expansion ob leeg yuav nqa tawm nrog kev pab los ntawm sealants, uas yog siv tom qab kawm tiav ntawm lub tsev hauj lwm. Qhov no embodiment muaj xws li leeg sau ob-tivthaiv muaj pes tsawg leeg, uas muaj high adhesion zog qhob. Lub luag hauj lwm ntawm lub substrate rau mounting ib tug sealant txheej thov Sealer, nws dav yuav tsum ua raws nrog qhov loj ntawm lub leeg.

O waterproofing expansion pob qij txha tau yooj yim tiv thaiv cov ntaub ntawv nyob rau hauv ib yam uas yog lub feem ntau yooj yim, tab sis muaj ib co kev txwv on ua hauj lwm. Lawv hais nyob rau hauv lub me me leeg dav uas tsis pub tshaj 30 mm, whereas nws deformability yuav tsum tsis txhob yuav ntau tshaj 15%. Ntawm lwm yam, tus tsim, txhais nyob rau hauv xws li ib tug txoj kev, yuav tsum tsis txhob muaj ib tug tsis tu ncua siab ntawm av.

Nyob rau hauv thiaj li yuav muab lub leeg xws deformation uas yuav tsum tau siv nyob rau hauv tus ntawm siab ntawm lub hauv qab av, nyob rau hauv tas li ntawd mus rau txoj kev yuav tsum tau siv cov kev tiv thaiv cover canceller, uas yog ua los ntawm 0.5 hli stainless steel ntawv.

Kev siv cov saj zawg zog membrane

Thaum tsim nyog waterproofing expansion ob leeg yuav ua rau kom nws cov dav, thiab ces siv ib tug saj zawg zog membrane. Nyob rau hauv "Lastin C" yuav ua raws li nws. Nws installation yog nqa tawm los ntawm kho nrog hlau clamps rau lub pob zeb ua ntug. Pre-ua nto sealant uas muaj high adhesiveness.

Tsawg ntawm cov qauv no yog hais tias nws yog tsis tau thov kom cov chaw uas yog lossi raug mus rau lub siab ntawm av. Yog hais tias xws tej yam kev mob uas tau ntsib, ces nyob rau hauv tas li ntawd ib tug tiv casing canceller yuav siv tau rau ib tug membrane, uas yog ua los ntawm stainless hlau. Lub ntsiab lub luag hauj lwm ntawm waterproofing rau saum toj no tshuab tej zaum yuav siv cov ntaub ntawv tob tob. Lawv thov kom lub pob zeb nto thiab ua rau nws waterproof. Ib tug disadvantage ntawm xws waterproofing qhia tias cov tsim ntawm tej kab nrib pleb qauv yuav tsis tau kev ncaj ncees ntawm lub waterproofing, ua allergic ntawm cov dej mus rau hauv lub tsev.

Siv lub haum neeg

Waterproofing expansion ob leeg yuav tsum tau siv cov haum neeg, uas muaj rau hauv daim ntawv ntawm profiles ntawm PVC los sis roj hmab. Nyob rau tib lub sij hawm muab waterproofing qhov tseem ceeb uas yog ua thaum lub sij hawm ntawm tiav ntawm monolithic qhob ua hauj lwm. Nyob rau hauv lub chav kawm ntawm xws manipulations nyob rau hauv lub formwork tshwj xeeb inserts yuav tsum tau kev txhawb, siv lawv tom qab pouring lub pob zeb yuav tau tsim expansion ob leeg waterstop concreted, nws yuav nyob rau hauv lub qab nthab los yog phab ntsa.

Waterstop ua los ntawm ntaub ntawv sib txawv, xws li PVC los sis roj hmab. Lawv muaj ntau yam ntaub ntawv thiab installation txoj kev nyob rau hauv ib tug monolithic qauv. Thaum nqa waterproofing pob qij txha ntawm xws li ib tug txheej txheem yuav tsum tau borne nyob rau hauv lub siab hais tias nyob rau hauv cov nuj nqis ntau hom kev lag luam nyob rau hauv lub stretch kev taw qhia, compression ntawm lub longitudinal thiab transverse ua haujlwm, raws li zoo raws li lub dej siab yuav ua tau txawv. Txhua yam yog nyob ntawm seb assumed lim, uas yuav txiav txim seb lub hom ntawm tus yuam sij. Nyob rau hauv tas li ntawd, ib tug tshwj xeeb qib ntawm qhob siv rau waterproofing, uas muaj qualities ntawm dej kuj. Xwb, lub waterproofing yuav siv tau, uas yog raws li nyob rau hauv ib tug nyias nyias rau underground lug.

Siv cov tso cov ntaub ntawv uas

Waterproofing pob qij txha sab hauv tsev yuav tau ua los ntawm kev siv ib tug polymer bitumen khoom uas yog muab tso rau ib ncig ntawm lub Fusing txoj kev. Ntawm lwm yam, thov ib tug tourniquet sealing. Qhov no system yog ntsia tom qab kawm tiav ntawm lub tsev pob zeb ua hauj lwm. Surfaced khoom uas muaj tsis muaj lub hauv paus, muaj ib tug coefficient ntawm transverse thiab longitudinal elongation ntawm so ntawm 1000%. Qhov no qhia tau hais tias lub waterproofing yuav ncab 10 lub sij hawm.

Rau cov yog vim li cas hais tias cov ntaub ntawv uas nkag rau hauv yob ntawm ib tug dav xws li los ntawm 330 hli 1000 hli, nws yuav siv tau rau tag nrho cov hom ntawm cov pob qij txha. Qhov no tej zaum yuav lub nqaws nyob rau juncture ntsug thiab kab rov tav daim hlau nyob rau hauv lub angular pob qij txha thiab nqaws ntawm complex configuration. Fits surfaced khoom siv roj burner. Thaum xws li ib tug waterproofing pob qij txha nyob rau hauv underground lug, resizing yuav ncav cuag 50 hli tsis muaj cov kev txwv. Yog hais tias cov nqi no yog ua zoo tshaj, koj yuav tsum siv lub complex, uas muaj xws li kev siv cov txhaj tshuaj tshuab.

Siv waterproof "Neodymium"

Waterproofing pob qij txha ntawm "Neodymium" system yuav fusing lub txheej cov ntaub ntawv uas mus rau lub hauv ob sab phlu. Ntxiv sealing yog nqa tawm thaiv thiab kev tiv thaiv ntawm lub sab sauv weldable txheej txheej. Thaum pw tsim nyog los xav txog lub tshav kub kuj bitumen, uas yog 100 ° C. System los mus rau hauv cov nyhuv, yog tias lub ntsiab leeg waterproofing yog puas ntsoog.

Cov leeg ntawm predetermined siab kav yuav tsum tau noj ib tug tshwj xeeb Sealer uas penetrates tus txha kab noj hniav thiab ua rau nws kiag kaw. Rau lub system raws li ib tug thawj waterproofing siv polymer-bitumen membrane "Tegapar TP 431", uas yog resistant rau kev txhoj puab heev tej kev kawm, nws yog ib qho yooj yim rau nruab thiab muaj ib tug loj loj.

Nta ntawm kev siv ntawm waterstops

Waterproofing pob qij txha nyob rau hauv underground lug, Cheebtsam uas tej zaum yuav muaj li ntawm ib tug tshwj xeeb tseem ceeb, muaj hauv daim ntawv ntawm daim kab xev ntsia tau rau hauv lub formwork nyob rau theem thaum lub monolith yuav tsum tau sau qhov chaw. Qhov no tso cai rau koj mus tau tsiv expansion pob qij txha. Lub waterstop muaj ob peb tshwj xeeb kab noj hniav thiab tav, uas cov mounting caij yuav ua tau yooj yim thiab txhim khu kev qha kuas thiab ductility tebchaw.

Cov cuab yeej ntawm polyurethane sealant

Waterproofing cov pob qij txha los ntawm lub sab hauv, raws li hais saum toj no, tej zaum yuav nqa tawm siv ib tug polyurethane sealant. Yuav kom ua tau li ntawd, ntxuav lawv los ntawm cov laus waterproofing, plua tshauv thiab xoob hais ntawm qhob, nteg lub nras ntawm polyethylene ua npuas ncauj. Nws yuav tsum tau txo lub sealant noj. Lub puab nto yog kho nrog ib tug primer muaj pes tsawg leeg los txhim kho adhesion. Siv ib tug duav los yog sealant phom fits rau hauv cov kab noj hniav ntawm cov expansion ob leeg.

xaus

Yuav kom cov pob qij txha waterproofing cov rooj sib txoos tau tshaj txhim khu kev qha, thaum sau lawv nrog sealant nto yuav tsum tau smoothed nrog ib tug duav, siv xub npus dej, kom txog rau thaum koj yuav tau txais ib tug ca saum npoo. Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias tus mortgaged tourniquet yuav tsum loj sib koom dav yog 10 hli.
