Nyob rau hauv cov txheej txheem ntawm steel -edged roj hmab waterstops, pre- kho galvanized steel sawb yog muab tso rau hauv nruab nrab ntawm cov roj hmab thiab vulcanized. Lub zog adhesion ntawm ob muab qhov tseem ceeb seepage tiv thaiv thiab dej - nres. Lub hauv nruab nrab roj hmab lub cev ntawm cov embedded steel-edged waterstop yog compressed, stretched, thiab deformed thaum lub sij hawm tus txheej txheem deformation, yog li ua tau ib tug sealing thiab dej- nres muaj nuj nqi. Lub galvanized steel sawb tau zoo adhesion rau pob zeb, ua rau nws nyuaj rau detach los yog loosen, tso cai rau lub waterstop tiv taus ntau zog tensile thiab torsional zog. Thaum lub sij hawm tsim kho, lub zog vibration loj heev thiab nyuaj hauv kev kho thaum lub sij hawm ua vaj tse yuav ua rau cov roj hmab zoo tib yam hloov pauv, tsim kua muag, thiab ntswj, ua rau loosening thiab detachment, ua rau cov dej ntws tawm hauv dej siab. Txawm li cas los xij, thaum siv steel-edged roj hmab waterstops, tsis muaj cov pob qij txha tshiab tau tsim los ntawm cov hlau sawb thiab cov pob zeb, lossis ntawm cov hlau sawb thiab cov roj hmab. Yog li ntawd, steel-edged roj hmab waterstops txhim khu kev tiv thaiv seepage kev ua tau zoo ntawm cov qauv deformation, ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau qhov zoo ntawm kev tiv thaiv seepage thiab dej nres rau tag nrho qhov project. Tsis tas li ntawd, lawv nthuav tawm tus kheej zoo- kev ruaj ntseg tom qab kev teeb tsa, kov yeej qhov xav tau rau ntau yam txheej txheem kho thiab ua rau kev tsim kho thiab kev teeb tsa yooj yim dua.
Hlau -edged roj hmab waterstops yog cov khoom sib xyaw uas muaj cov roj hmab dav dav dav dav thiab galvanized steel ntug ntawm ob sab. Hom dej tso dej no feem ntau yog nyob ntawm qhov compression lossis ncab ntawm cov roj hmab hauv nruab nrab hauv cov pob zeb nthuav dav kom ua tiav kev sib khi thiab dej - nres. Feem ntau, qhov adhesion ntawm pob zeb thiab roj hmab tsis zoo. Hauv kev tsim kho, vim tias roj hmab yog cov khoom siv elastic, nws yog qhov nyuaj rau kev cog cov pob zeb thaum lub sij hawm nchuav. Yog li ntawd, thaum cov pob qij txha nthuav dav, tsim kua muag, los yog ntswj, cov roj hmab waterstop feem ntau loosens thiab ntog tawm, ua rau to hauv qab dej siab. Qhov teeb meem no tseem tshaj tawm rau cov pob qij txha nrog cov pob qij txha loj. Siv galvanized steel-edged roj hmab composite waterstops tuaj yeem kov yeej cov kev tsis txaus ntawm cov roj hmab ntshiab huv - hom waterstops. Tsis tas li ntawd, qhov sib xyaw waterstop no muaj kev ua haujlwm dual: ntawm ib sab, nws tuaj yeem txuas rau txoj kev seepage thiab qeeb tus nqi seepage; Ntawm qhov tod tes, galvanized steel ntug muaj qhov zoo adhesion rau pob zeb, tso cai rau cov dej ntws tawm kom tiv taus ntau dua tensile thiab torsional rog. Qhov no ua kom ntseeg tau tias cov roj hmab waterstop yuav tsis loosen los yog detach nyob rau hauv lub zoo deformation ntau yam ntawm cov pob zeb, yog li txhim kho cov dej - nres. Cov hlau-edged roj hmab waterstop siv galvanized steel ntug; cov roj hmab feem ntau yog cov roj hmab, cov roj hmab neoprene, lossis EPDM roj hmab. Yuav tsum muaj kev sib raug zoo ntawm cov roj hmab thiab cov ntug steel, nrog rau lub zog ntawm daim ntawv cog lus (peel zog) ntawm 80 ~ 10N / 2.5mm los tiv thaiv lawv los ntawm kev rub tawm los ntawm kev hloov pauv sab nraud. Feem ntau, tsis muaj txheej txheem qhov ntawm lub ntug steel. Thaum lub sij hawm installation thiab qhob pouring, lub waterstop thiab steel ntug yog ruaj nrog nyias hlau hlau los xyuas kom meej compaction thiab zoo, ruaj adhesion ntawm cov galvanized steel ntawv thiab cov pob zeb. Cov khoom no feem ntau yog siv rau hauv lub hauv paus engineering tej yaam num uas pob zeb yog cam khwb cia nyob rau hauv qhov chaw thiab muab tso rau hauv kev tsim kho pob qij txha thiab expansion pob qij txha los ua ib tug tseem ceeb ib feem ntawm cov pob zeb ua qauv, xws li underground chaw, tunnels thiab culverts, aqueducts, dams, thiab kua cia cov qauv.
