Ukutholakala kwezihlahla eziphuzwayo nezinhlobo ezinhle

Ipayipi ephathelene nezinhleke evela kwiqondo elikhokhiselwe ngaphansi kwezindawo zokuhlaba, izindawo zokuthutha, iyabhathelwe ngeqondo le Q235 elikhokhiselwe noma iyabhathelwe ngemigqa engaphambene yokukhanya, ngumtechno entsha. Iyasebenza ngokuzimela, ukufaka kuyenza ngokushesha, ukulawulwa kwezimali kungenzeka ngokushesha futhi kungcono ukulawulwa kwezimali, kuthatha indawo yemikhaya yembulelo ehlukene nezindlela, izindlela zokuthutha, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amathongwa, amath......

Ipayipi ephathelene nezinhleke ye-China

Imithwalo emibi yokulungisa ubunzima kwepayipi evela kwezinhlobo zokulayisha ipayipi ephathelene nezinhleke

(1) Imiphi yemiphiqulu yemifanekiso yemifanekiso ye-galvanized kufuneka inike isihatiso sokuhlelela phakathi ngokuhlala, akukho sertifikethi sokuhle kungahlali.

(2) Imiphi yemiphiqulu yemifanekiso ye-galvanized kufuneka ibuyiselwe ngokuphelele ngemuva kokuthi kweyindaweni yokudla. Akukho qhinga elikhanyisiweyo yokusebenzisa ngokuhlala kweyindaweni yokudla.

(3) Indawo yokulandela kwezokulandela kufuneka ikhange ukulinganisa. Kungabonakali ukukhuphuka, ukubuyisa futhi ukulawula ukuphakathi.

(4) Imiphi yemiphiqulu yemifanekiso ye-galvanized, ukuze uhlinde ukuthi iphinde iphinde kude kude, kufuneka uhlanze iphinde.

(5) Ukubekwa kanye nokulaywa kwezokulaywa zemiphi yemifanekiso ye-galvanized kufuneka kuhlale kancane, ukuphazamisa okuphansi kwezokulaywa akulondle ukuthi kungaphandle kwezindleke, izindleke, futhi izinto ezingenakho zokulandelwa kungaphakathi kwezokulaywa.

(6) Kufuneka kuthathwe izindlela eziphumelelayo ukuze uhlinde ukulinganisa kwezokulaywa zemiphi yemifanekiso ye-galvanized.

(7) Ngemva kokuqinisa isikulufa esiqinile, amalunga kufanele ambozwe ngento engaphuzi (noma i-asphalt eshisayo), bese kuba i-anti-corrosion yesibili.

Uma kuqhathaniswa ne-concrete evuselelwe, i-galvanized corrugated culvert inezinzuzo ezilandelayo:

1, ipayipi le-galvanized corrugated culvert kulula ukuligcina, yenza umsebenzi omuhle nje wokuvikela udonga lwangaphakathi.

2. Ukubamba iqhaza Iphayiphi ye-galvanized corrugated culvert inezinzuzo ezibonakalayo kwezomnotho endaweni yomhlabathi eqandisiwe yase-alpine nasezindaweni zomgwaqo onomhlabathi omnene.

3, ipayipi le-galvanized corrugated culvert ngemuva kokwelashwa kwe-anti-corrosion okuhlala isikhathi eside.

4, galvanized olwalugqwaliwe tube umsele ubuqotho ezinhle, plasticity izimo eziyinkimbinkimbi geological esigabeni ukumelana ukusonteka.

5, galvanized olwalugqwaliwe umsele wokugubha tube conductivity ezinhle ezishisayo endaweni permafrost of the ukuphazamiseka subgrade incane, ukuzinza roadbed.

6, ipayipi yoculvert ezigqagqwe ngokwezimali yenziwa ngokwezindustriali, ukwenziwa akuthinte ngendawo futhi kuyindlela yokuphatha ubungozi.

7, ipayipi yoculvert ezigqagqwe ngokwezimali yenziwa ngokuhlanganisa, umthombo omfushane, ubunzima obuncane, ukufaka kuyenza ngokushesha, kuzindaweni ezithile ukuncipisa ukusebenzisa abasebenzi ngokweqile, futhi kuyenzakanyekelwe ukwenza kunezinyanga ezibomvu.
