Cov Lus Qhia
Kauj ruam 1
Laij cov voj hauv av. Txhawm rau kom raug xam ntawm lub voj voos hauv av, koj yuav tsum paub tus nqi ntawm cov av tiv thaiv hauv koj thaj chaw. Txhawm rau kev suav tseeb, koj tuaj yeem siv cov khoos phis tawm tshwj xeeb lossis cov qauv uas coj mus rau ntau lub tswv yim ntsuas. Koj tuaj yeem nrhiav cov qauv ntawd hauv cov ntawv tshwj xeeb.
Kauj ruam 2
Xaiv qhov chaw rau lub voj hauv av. Nws yuav tsum raug sau tseg tias nws yog qhov yuav tsum tau muab tso rau qhov nkhaus ntawm qhov deb ntawm tsawg kawg ib metres los ntawm lub hauv paus ntawm lub tsev, hauv qhov chaw mus xyuas me ntsis.
Kauj ruam 3
Npaj cov electrodes. Nws raug nquahu kom siv steel fab 2.5-3 m ntev thiab tsawg kawg 50 hli dav li electrodes.
Kauj ruam 4
Khawb ib daim duab peb ceg lossis square trench nrog qhov tob ntawm 0.8-1 m. Nws yuav tsum nco ntsoov tias qhov kev ncua deb ntawm cov electrodes yuav tsum muaj qhov sib luag rau qhov ntev ntawm cov electrodes no.
Kauj ruam 5
Siv ib qho kab sib zog ua ke kom tsav cov electrodes mus rau hauv cov ces kaum ntawm trench.
Kauj Ruam 6
Siv ib txoj hlua hlau thiab txuas rau txhua qhov ntawm cov electrode pins uas tau tsav mus rau hauv av. Nws raug nquahu los txuas lub sawb rau ob tog ntawm kaum tsev. Ntsuam xyuas weld zoo. Ua tib zoo kho cov hlau sib txuas nrog bitumen mastic lossis lwm cov tshuaj tiv thaiv corrosion.
Kauj Ruam 7
Rub cov kab txaij kom dhau los ntawm daim hlau thaiv-hauv daim hlau tiv thaiv thiab muab daim phiaj rau hauv av. Yog tias qhov no ua tsis tau, nws raug nquahu kom muab cov xaim tooj liab nrog ntu ntu ntawm tsawg kawg 10 sq. Mm rau kab txaij. Koj tuaj yeem txuas cov hlau siv ntsia liaj qhov rooj, ntxhua khaub ncaws thiab txiv ntoo. Ua tib zoo kho qhov sib txuas ntawm txoj hlua hlau nrog txoj hlua nrog ib txheej kom tsis pub xeb.
Kauj ruam 8
Khawb cov trench thiab compact av kom huv si.
