Cov kua ua kua yog ib qho tseem ceeb thiab qee zaus tseem ceeb heev ntawm txoj kev loj hlob ntawm ib thaj av ntawm thaj av uas muaj txua ntoo. Cov cuab yeej ntawm cov kua hauv ib qhov chaw tso cai rau kom tsis txhob tsuas yog cov nyom los yog ib lub vaj teb, tab sis kuj yog cov neeg nyob thiab cov koom haum pab.
Cov dej ntawm suburban cheeb tsam muaj ob lub ntsiab hom: qhib (nto) thiab kaw (underground) system.
Nws yog ib qho yooj yim heev kom nkag siab txog qhov yuav tsum tau tsim kom muaj xws li ib tug qauv, nws tsuas yog tsim nyog los kwv yees cov theem ntawm ntuj moistening los ntawm hauv av thiab saum npoo dej. Cov kua dej ntawm lub vev xaib, nws cov hom thiab tsim nta nyob ntawm seb qhov ntim twg, qhov tsawg zaus ntawm cov khoom noj thiab ntau hom kev ya raws.
Cia peb xav paub seb yuav ua li cas thiaj li ntws tawm ntawm qhov chaw, nrhiav lawv cov hom phiaj thiab cov yam ntxwv ua haujlwm. Tab sis nws yuav tsum nco ntsoov hais tias cov creation ntawm cov kua fais fab, lawv xaiv thiab tsim ntawm ib qhov project yog ib qho yooj yim engineering ua hauj lwm, yog li nws yog zoo dua rau kev tso siab rau cov kws tshwj xeeb.
Qhov dej ntws tawm ntawm qhov chaw
Lub kaw lus qhib kua dej yog ib los yog ob peb lub kwj deg uas xa dej tawm sab nraum lub vev xaib mus rau cov dej haus ntau. Xws li ib txoj hauv kev tsuas yog siv tau rau tshem tawm cov dav hluav taws kub thiab dej qhuav. Yog li ntawd, cov dej ntws tawm ntawm lub vev xaib siv rau hauv cov kev txwv, xws li:
- yog hais tias lub site muaj av nplaum av thiab nyob hauv cov lowland;
- yog tias qhov chaw nyob ntawm ib txoj kab nqes, ntawm nws ko taw;
- Yog hais tias lub vev xaib nyob rau laj kab thiab cov tuam tsev nrog lub hauv paus sib sib zog nqus.
Nws yog qhov yooj yim los tsim kom muaj xws li cov kua dej ntawm lub tsev kawm ntawv nrog koj txhais tes: tsuas yog ob peb ditches tob mus rau ib nrab ntawm ib lub meter nrog bevelled npoo raws perimeter ntawm lub tsev kawm ntawv. Txhawm kom muaj kev ziab tshoob tawm ntawm cov kua fais fab, nws xav tau kev kho yooj yooj yim: cov kwj deg yuav tsum tau ntxuav cov khib nyiab, nroj tsuag thiab av.
Cov kua uas kaw ntawm qhov chaw
Yog hais tias xav tau ua kom cov dej tob hauv qhov chaw, cov kua dej yuav tsum raug kaw los yog hauv av. Xws li ib qho system zoo rau tshem tawm cov av hauv qhov tob ntawm 2.5-3 meters.
Cov kua dej kaw - lub tshuab ua haujlwm engineering - yog lub kaw lus ntawm cov kav dej (qhov dej tshav) hauv kev sib tshuam nrog qhov tob ntawm 1 mus rau 2 meters. Cov dej yog qhov tseem ceeb thiab tseem ceeb tshaj plaws ntawm lub cev. Qhov nrov tshaj plaws yog cov yas perforated kav nrog ib lim tshwj xeeb lim hnab.
Rau cov dej zoo dua, cov dej ntshau yog npau npau, cov txhauv, txhuam hniav, thiab lwm cov ntaub ntawv zoo sib xws. Cov kav dej thiab cov kav dej ntawm lub kaw lus yuav tsum yog nyob rau hauv txoj kab nqes ntawm cov dej kom tsawg. Ntxiv mus, qhov ntau dua no lub kaum ntse ntse, qhov ntau dua ntawm kev ua si ntawm dej ntau thiab, raws li, qhov ua tau zoo
Kev tsim cov kev tsim tawm ntawm lub plhaub tiab ntawm cov av thaj tsam yuav tsum muaj kev lag luam zoo xws li kev ntsuas ntawm qhov ntim thiab qhov tob hauv av, thiab cheeb tsam thiab hom av uas yuav tsum tau muab pov tseg. Yog tias koj ua tiav tag nrho cov uas yuav tsum tau ua rau txoj haujlwm no, xws li lub kaw lus yuav ntev ntev tsis muaj kev cuam tshuam. Nyob rau hauv tus txheej txheem ntawm kev khiav hauj lwm, nws kuj yog tsim nyog
- ua kom tiav rau qee yam kev mob, uas yog:
- periodically (tsawg kawg ib zaug txhua txhua peb lub xyoo) lub cev yuav tsum tau tu cov khoom tawg thiab silting;
- Tsis txhob txhim kho vaj tse thiab siv cov khoom siv hnyav tshaj li cov kav dej kua fais fab;
- Nws yog ib qhov tsim nyog yuav tau nqa tawm lub caij nyoog xoob ntawm cov av saum cov dej ntshiv kom ceev cov kab lim dej ntawm cov av.
Ua raws li cov kev cai yooj yim thiab ntws qhov chaw yuav ua tiav!
