Cov kev ceev faj txog kev tsim kho cov kav dej corrugated steel hauv cov huab cua sib txawv thiab cov xwm txheej huab cua

Nyob rau hauv cov huab cua sib txawvlub raj xa dej corrugated steelKev ceev faj txog kev tsim kho tsis zoo ib yam, lub caij ntuj no thiab lub caij ntuj sov, qhov kub siab thiab qhov kub qis, qhov chaw ib puag ncig sib txawv kev ntsuas kev tsim kho kuj txawv.

 

1.Kev ntsuas kev tsim kho corrugated culvert huab cua kub siab

Ø Thaum cov pob zeb ua vaj tse raug tsim thaum lub sijhawm kub, cov dej sib tov yuav tsum tau siv los ua cov txheej txheem txias kom tswj tau qhov kub ntawm cov pob zeb hauv qab 30 ℃, thiab yuav tsum xav txog qhov cuam tshuam ntawm qhov kub siab rau qhov poob ntawm cov pob zeb tawg. Cov pob zeb yuav tsum tsis txhob sib tov nrog dej thaum lub sijhawm thauj mus los. 

Ø Yog tias muaj tej yam mob, nws yuav tsum tau npog thiab tiv thaiv los ntawm lub hnub kom txo qhov kub ntawm cov formwork thiab cov khoom siv txhawb nqa; dej kuj tseem tuaj yeem txau rau ntawm cov formwork thiab cov khoom siv txhawb nqa kom txo qhov kub, tab sis yuav tsum tsis txhob muaj dej ntws lossis lo rau hauv cov formwork thaum lub sijhawm nchuav cov pob zeb.

Ø Cov tsheb thauj khoom siv sib tov yuav tsum muaj cov khoom siv sib tov, thiab cov thoob dej yuav tsum tau tiv thaiv kom tsis txhob raug tshav ntuj. Ø Cov khoom siv sib tov yuav tsum tau sib tov qeeb qeeb thiab tsis tu ncua thaum lub sijhawm thauj mus los thiab lub sijhawm thauj mus los yuav tsum tau txo qis.

Ø Cov formwork yuav tsum tau rhuav tshem thaum qhov kub qis dua thaum nruab hnub thiab qhov chaw ntawm cov pob zeb yuav tsum tau noo thiab kho kom zoo rau tsawg kawg 7 hnub tom qab rhuav cov formwork.

 

2.Cov kev ntsuas rau kev tsim kho ntawmcorrugated steel culvert yeeb nkabthaum lub sijhawm los nag

Ø Kev tsim kho thaum lub sijhawm los nag yuav tsum tau npaj ua ntej, sim npaj kom ua tiav ua ntej nag los, cov chaw tiv thaiv dej nyob ib puag ncig lub qhov kom tiv thaiv cov dej nyob ib puag ncig kom tsis txhob ntws mus rau hauv lub qhov.

Ø Ua kom muaj zaus ntawm kev ntsuas cov dej ntawm cov xuab zeb thiab pob zeb, kho qhov sib piv ntawm cov pob zeb kom raws sijhawm kom ntseeg tau tias qhov zoo ntawm kev sib tov pob zeb.

Ø Cov kav dej hlau corrugated culvert yuav tsum tau ua kom muaj zog kom tiv thaiv kev xeb. Ø Thaum txuas cov kav dej hlau corrugated culvert, yuav tsum teeb tsa chaw nkaum nag ib ntus kom tiv thaiv kev xeb los ntawm dej nag.

Ø Yuav tsum tau ua tib zoo saib xyuas cov kab hluav taws xob, lub thawv hluav taws xob ntawm cov khoom siv hluav taws xob hauv tsev yuav tsum tau npog thiab yuav tsum tau ntsuas kom tsis txhob muaj dej noo, thiab cov xov hluav taws xob yuav tsum tau rwb thaiv tsev zoo kom tiv thaiv kev xau thiab kev raug hluav taws xob.

 

3. Kev ntsuas rau kev tsim kho ntawm cov ntawv corrugatedyeeb nkab steelthaum lub caij ntuj no

Ø Qhov kub ntawm ib puag ncig thaum lub sijhawm vuam yuav tsum tsis txhob qis dua -20 ℃, thiab yuav tsum tau ntsuas kom tiv thaiv daus, cua thiab lwm yam kev ntsuas kom txo qhov sib txawv ntawm qhov kub ntawm cov pob qij txha vuam. Cov pob qij txha tom qab vuam raug txwv tsis pub kov dej khov thiab daus tam sim ntawd.

Ø Qhov sib piv ntawm kev sib tov thiab kev poob ntawm cov pob zeb yuav tsum tau tswj hwm nruj thaum sib tov cov pob zeb thaum lub caij ntuj no, thiab cov pob zeb sib xyaw yuav tsum tsis txhob muaj dej khov thiab daus thiab cov pob khov. Ua ntej pub, yuav tsum siv dej kub lossis pa dej los ntxuav lub lauj kaub sib tov lossis lub nruas ntawm lub tshuab sib tov. Qhov kev txiav txim ntawm kev ntxiv cov ntaub ntawv yuav tsum yog cov pob zeb sib xyaw thiab dej ua ntej, thiab tom qab ntawd ntxiv cov cement tom qab sib tov me ntsis, thiab lub sijhawm sib tov yuav tsum ntev dua 50% dua li ntawm chav sov.

Ø Kev nchuav pob zeb yuav tsum xaiv hnub ci thiab xyuas kom meej tias nws ua tiav ua ntej txias, thiab tib lub sijhawm, nws yuav tsum tau rwb thaiv tsev thiab tswj hwm, thiab yuav tsum tsis txhob khov ua ntej lub zog ntawm pob zeb ncav cuag cov qauv tsim.

Ø Qhov kub ntawm cov pob zeb ua vaj tse tawm ntawm lub tshuab yuav tsum tsis txhob qis dua 10 ℃, nws cov khoom siv thauj khoom yuav tsum muaj kev ntsuas rwb thaiv tsev, thiab yuav tsum ua kom lub sijhawm thauj mus los luv dua, qhov kub thiab txias rau hauv pwm yuav tsum tsis txhob qis dua 5 ℃.

Ø Cov tsheb thauj khoom siv pob zeb yuav tsum muaj cov kev ntsuas txuag cua sov, thiab txo lub sijhawm thauj khoom ntawm cov pob zeb.
