Cov txheej txheej saum toj kawg nkaus ntawm daim nyias nyias daim pam tsis muaj dej tsis muaj dej yog cov khoom siv high-density polyethylene (HDPE) zaj duab xis, thiab cov txheej hauv qab yog cov ntaub tsis-woven. Ib txheej ntawm high-density polyethylene (HDPE) zaj duab xis yog glued rau nws. Bentonite waterproof pam muaj zog waterproof thiab anti-seepage muaj peev xwm tshaj li bentonite waterproof pam. Lub tshuab dej tsis zoo yog tias cov khoom bentonite swell nrog dej los tsim ib qho kev sib txuam colloidal. Raws li kev txwv ntawm ob txheej ntawm geotextiles, bentonite nthuav tawm los ntawm kev tsis sib haum xeeb rau kev txiav txim. Qhov tshwm sim ntawm kev nqus dej tas li thiab nthuav dav yog ua kom cov bentonite txheej nws tus kheej ntom. , thiaj li muaj cov nyhuv waterproof.
Lub cev yam ntxwv ntawm zaj duab xis-coated waterproof daim pam:
1. Nws muaj cov dej tsis zoo thiab tiv thaiv kev ua haujlwm, cov dej ntws los tiv thaiv dej tuaj yeem ncav cuag ntau dua 1.0MPa, thiab cov permeability coefficient yog 5 × 10-9cm / s. Bentonite yog cov khoom siv ntuj tsim, uas yuav tsis raug kev laus cov tshuaj tiv thaiv thiab muaj kev ua haujlwm zoo; Ib qho kev cuam tshuam tsis zoo rau ib puag ncig yog cov khoom siv ib puag ncig
2. Nws muaj tag nrho cov yam ntxwv ntawm cov ntaub ntawv geotextile, xws li kev sib cais, kev txhawb zog, kev tiv thaiv, pom, thiab lwm yam. Kev tsim kho yog yooj yim thiab tsis txwv los ntawm kev tsim kho qhov kub thiab txias, thiab nws kuj tuaj yeem tsim hauv qab 0 ° C. Thaum lub sij hawm tsim kho, tsuas yog nteg lub GCL waterproof pam rau hauv av, kho nws nrog rau tes thiab ntxhua khaub ncaws thaum tsim lub façade los yog txoj kab nqes, thiab ceg tawv raws li xav tau.
3. Yooj yim kho; Txawm tias tom qab qhov kev tsim kho dej tsis zoo (seepage) tiav, yog tias cov txheej txheem dej tsis zoo raug puas tsuaj, tsuav yog qhov kev puas tsuaj tsuas yog kho, cov dej tsis zoo tuaj yeem rov qab tau zoo li nws tau ua.
4. Qhov kev ua tau zoo-nqi piv yog qhov siab, thiab kev siv dav heev.
5. Qhov dav ntawm cov khoom tuaj yeem ncav cuag 6 meters, uas phim cov specifications ntawm thoob ntiaj teb geotextile (membrane), uas zoo heev txhim kho kev tsim kho efficiency.
6. Nws yog qhov tsim nyog rau kev tiv thaiv kev tawm tsam thiab kev tawm tsam kev tawm tsam hauv thaj chaw ntawm cov dej tsis zoo thiab kev tiv thaiv kev tawm tsam, xws li: qhov av, subways, hauv qab daus, cov kab hauv av, ntau cov vaj tse hauv av thiab cov dej num uas muaj cov dej hauv av nplua nuj.
