1. Lub hauv paus tsis zoo ntawm cov raj xa dej yuav ua rau qhov tsis sib xws ntawm cov raj xa dej thiab lub hauv paus, feem ntau tsim ib feem ntawm cov dej, thiab nyob rau hauv cov xwm txheej hnyav, cov kav dej yuav tawg lossis qhov cuam tshuam yuav tawg.Cov kav hlau kav dej tau muab faib ua qhov hloov pauv tau yooj yim, flange interfaces, kev sib txuas ntawm tus kheej thiab kev sib txuas tsis sib xws raws li cov ntaub ntawv sib txawv.Cov kev ceev faj hauv qab no yuav tsum tau ua:
(1) Ua tib zoo tsim raws li kev npaj yuav tsum tau ua kom muaj zog thiab ruaj khov ntawm cov kav dej hauv paus.Thaum lub hauv paus hauv paus geology thiab hydrology tej yam kev mob tsis zoo, cov av hloov yuav tsum tau nqa tawm los txhim kho kev kho mob los txhim kho lub peev xwm ntawm cov hauv qab ntawm lub hauv paus trench.
(2) Yog tias cov av nyob hauv qab ntawm lub tank raug cuam tshuam los yog ntub dej, cov av mos yuav tsum tau khawb ua ntej, thiab tom qab ntawd cov txheej txheem excavated yuav tsum tau muab rov qab thiab compacted nrog cov ntaub ntawv zoo xws li xuab zeb lossis pob zeb. .
(3) Thaum khawb av hauv qab cov dej hauv av, cov txheej txheem yuav tsum tau ua kom ua tau zoo ntawm cov dej thiab dewatering hauv qab ntawm lub hauv paus trench.Yog tias tsim nyog, txhawm rau txhawm rau txhawm rau khawb cov trenches qhuav, yog tias tsim nyog, 20cm-30cm tuab av txheej tuaj yeem khaws cia rau hauv qab ntawm trench rau kev tsim kho tom ntej.Khawb thiab kaw thaum twg los tau.
2. Tus nqi ntawm cov yeeb nkab raw cov ntaub ntawv tsis zoo, muaj cov kab nrib pleb lossis cov pob zeb ntawm cov yeeb nkab phab ntsa yog xoob, impermeability tsis zoo, thiab cov dej xau tuaj yeem yooj yim.Cov kav dej kav dej yog siv rau cov kav dej, cov kav dej thiab cov kav dej xa hluav taws xob, thiab nws suav nrog cov kav hlau ncaj ncaj thiab fittings.Cov kav hlau kav hlau tsis tshua muaj zog.Raws li kev sib txawv casting, nws tau muab faib ua cov kav hlau txuas txuas ntxiv thiab cov centrifugal cam khwb cia hlau kav, ntawm cov centrifugal cam khwb cia hlau kav txuas ntxiv muab faib ua cov xuab zeb pwm thiab hlau pwm.
3. Cov yeeb nkab sib koom ua ke thiab kev tsim kho tsis zoo, thiab kev sib koom ua ke yog tawg nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam.Txoj kev tiv thaiv: xaiv qhov sib koom ua ke nrog cov khoom zoo heev thiab sib tw raws li kev sim.
