Cov ntaub thaiv dej uas muaj peb sab sib xyaw ua ke yog cov khoom siv los thaiv dej uas siv ntau hauv cov haujlwm loj. Yog li, yuav tsum txuas nws li cas thaum lub sijhawm tsim kho?
1. Kev hloov kho qhov sib koom ua ke
Thaum tso lub vas dej sib xyaw ua ke peb-seem, kho qhov kev taw qhia ntawm cov khoom dov kom ntseeg tau tias qhov ntev ntawm cov khoom dov yog perpendicular rau qhov kev taw qhia tseem ceeb ntawm txoj kev lossis qhov project. Qhov kev hloov kho no tso cai rau lub vas dej ntws kom tswj tau qhov kev ua haujlwm ntws ruaj khov thaum nqa cov khoom thauj, ua kom zoo dua txoj kev ntws dej, thiab txhim kho kev ua haujlwm ntws dej. Yog tias qhov kev taw qhia raug kho tsis raug, nws yuav ua rau cov dej ntws tsis zoo lossis cov dej hauv zos sib sau ua ke, cuam tshuam rau qhov cuam tshuam ntawm qhov project.
2. Cov khoom siv xaus thiab sib tshooj
Lub vas dej sib xyaw ua ke peb-seem yuav tsum tau xaus, thiab cov geotextiles ntawm cov geonet cores uas nyob ib sab yuav tsum tau sib tshooj raws li qhov kev taw qhia ntawm cov khoom siv dov. Thaum sib tshooj, xyuas kom meej tias cov geotextile yog tiaj tus thiab tsis muaj wrinkle, thiab qhov ntev sib tshooj ua tau raws li qhov yuav tsum tau tsim. Feem ntau, qhov ntev sib tshooj ntev tsis tsawg dua 15cm, thiab qhov ntev sib tshooj hla yog tswj hwm hauv qhov ntau ntawm 30-90cm. Qhov ntev sib tshooj tsis txaus yuav ua rau lub zog tsis txaus ntawm qhov sib koom ua ke, cuam tshuam rau kev ruaj khov ntawm lub vas dej; thaum sib tshooj ntau dhau yuav ua rau cov khoom pov tseg thiab kev tsim kho nyuaj.
3. Siv cov khoom sib txuas
Hauv kev ua cov khoom sib koom ua ke, kev xaiv thiab siv cov khoom sib txuas yog qhov tseem ceeb heev. Feem ntau, cov yas dawb lossis daj buckles lossis cov hlua polymer yog siv los txuas cov geonet cores ntawm cov geotextile yob uas nyob ib sab. Thaum txuas, siv cov khoom sib txuas los kho lawv ntawm qee lub sijhawm (xws li 30cm lossis 1m) raws li qhov ntev ntawm cov khoom yob. Cov khoom sib txuas yuav tsum muaj lub zog thiab kev ua haujlwm ntev txaus kom ntseeg tau tias cov pob qij txha ruaj khov. Yog tias cov khoom sib txuas raug siv tsis raug, cov pob qij txha yuav xoob lossis poob tawm, cuam tshuam rau cov dej ntws ntawm cov dej ntws.
4. Kev kho cov geotextiles uas sib tshooj
Yog tias lub vas dej sib xyaw ua ke peb-seem tau muab tso rau nruab nrab ntawm lub hauv paus, lub hauv paus thiab lub hauv paus qis, cov geotextiles uas sib tshooj yuav tsum tau kho. Cov txheej txheem kho suav nrog kev vuam wedge tas mus li, kev vuam lub taub hau tiaj lossis kev xaws. Thaum vuam, xyuas kom meej tias cov vuam zoo nkauj, zoo nkauj thiab tsis muaj kev vuam plam thiab dhia; thaum xaws, kev xaws lub taub hau tiaj lossis kev xaws dav dav tuaj yeem siv los ua kom tau raws li qhov yuav tsum tau ua kom tsawg kawg nkaus. Kev kho tuaj yeem txhim kho lub zog thiab kev ruaj khov ntawm cov pob qij txha thiab tiv thaiv cov geotextiles kom tsis txhob raug tshem tawm lossis puas tsuaj thaum lub sijhawm teeb tsa cov khoom sau.
5. Kev kho mob ib puag ncig tshwj xeeb
Hauv cov chaw tshwj xeeb, xws li thaum muaj cov pob zeb loj loj rau ntawm qhov chaw ntawm lub hauv paus pob zeb, txhawm rau tiv thaiv nws kom tsis txhob tho qhov geomembrane tiv thaiv kev seepage, ib txheej nyias ntawm cov xuab zeb sib xyaw (tuab 3-5cm) yuav tsum tau nthuav thiab dov rau ntawm qhov chaw ntawm lub hauv paus pob zeb. Cov txheej xuab zeb yuav tsum npog tag nrho qhov chaw ntawm lub hauv paus pob zeb, thiab yuav tsum tsis muaj xuab zeb nrog qhov loj me ntau dua 4 hli hauv cov txheej xuab zeb. Thaum tsim kho hauv qhov chaw txias lossis kub siab, yuav tsum tau ua cov kev tiv thaiv tsim nyog, xws li cov khoom sib txuas cua sov thiab kho lub sijhawm tsim kho, kom ntseeg tau tias qhov zoo ntawm cov pob qij txha tsis cuam tshuam los ntawm ib puag ncig.
Raws li pom tau los ntawm cov saum toj no, kev kho mob sib koom ua ke ntawm lub vas dej ntws peb-seem yog qhov txuas tseem ceeb hauv cov txheej txheem tsim kho, uas muaj feem cuam tshuam ncaj qha rau cov nyhuv ntws thiab kev ruaj khov ntawm lub vas dej ntws. Ua raws li cov lus qhia ntawm kev hloov kho qhov kev taw qhia sib koom ua ke, kev xaus cov khoom siv thiab kev sib tshooj, kev siv cov khoom sib txuas, kev kho geotextile sib tshooj thiab kev kho ib puag ncig tshwj xeeb tuaj yeem ua kom muaj zog thiab ruaj khov ntawm cov pob qij txha thiab txhim kho kev ua haujlwm ntws thiab lub neej ua haujlwm ntawm lub vas dej ntws.
