Dhizaini: Murwi weSimbi Unokiya, kuvhurika kwemvura ≤1×10⁻⁷ cm/s

America: Inosangana neASTM D5887 Standard yeLiner yekuderedza Kubuda Kwemvura Pasi peMadhiramu

Kumaodzanyemba kwakadziva kumabvazuva kweAsia: Mvura inodzivirira mvura pasi pevhu kuti isapinda mumwaka wemvura inonaya munzvimbo dzinopisa

GB/T 20933 Hot Rolled Q235B Q355B Steel Sheet Pile Maitiro ekugadzira

1.Sarudzo yezvinhu zvisina kuchena

Zvishandiso zvesimbi zvemhando yepamusoro zvekabhoni (Q235B / Q355B) zvinosarudzwa nokungwarira uye zvinoedzwa kuona kuti kuumbwa kwemakemikari kunoenderana nezvinodiwa zveGB/T 20933.

2. Kupisa kweBillet

Zvidimbu zvesimbi zvinodziiswa muchoto chinodziiswazve kusvika panosvika1150–1250°C, kuve nechokwadi chekuti tembiricha yakafanana kuti ishande zvakanaka pakutenderera.

3. Kutenderera Kwekutanga (Kutenderera Kwakaoma)

Mabhiritsi anopisa anopfuudzwa nemumagayiro akakombama kuti aderedze ukobvu uye agadzire maumbirwo ekutanga.

4. Kupedzisa Kutenderedza

Simbi inogadziriswazve kuburikidza nemagetsi ekupedzisa kuti iwane saizi chaiyo, ukobvu, uye hunhu hwemakanika hunodiwa pamapepa esimbi.

5. Kugadzira Mbiri

Uchishandisa michina yekumonera yakagadzirwa nehunyanzvi, simbi yacho inoumbwa kuitaMapepa emhando yeU kana Z, kuve nechokwadi chekuti mipendero yakanyatsobatana kuti ishandiswe pakuvaka.

6. Kutonhodza Kunodzorwa

Matanda emapuranga anotonhodzwa nemhepo inodzorwa kana kuti anotonhodzwa nekukurumidza kuti agadzirise chimiro chezviyo uye awane simba rinodiwa uye kusimba.

7.Kururamisa & Kurongeka

Matanda epepa apedzwa anotwasanudzwa uchishandisa michina yekuenzana kuti ive nechokwadi chekuti mativi acho akarurama uye kuti akaenzana zvakanaka.

8. Kucheka & Kureba Kwekugadzirisa

Matanda esimbi anochekwa kusvika pakureba kunodiwa (kazhinji6m–18m) ine sarudzo yekupedzisa kana kucheneswa kwemadziro.

Sei Uchifanira Kusarudza Simbi yeChina yeSimbi?

1. Simba Rakakwirira & Kugara Kwenguva refu
Magiredhi esimbi eQ235B neQ355B anopa goho rakanaka uye simba rekusimba, kugona kwakanaka kwekutakura mutoro uye kugadzikana kwechimiro kwenguva yakareba munzvimbo dzakaoma dzekuvaka dzakadai seMarine neFoundation application.

2. Mapurofayiri Akawanda Anowanikwa
TinopaMapepa emhando yeU neZine masisitimu akarurama ekukiyira, zvichipa muvaki runyorwa rwesarudzo dzekugadzira dzinochinjika kuti dzisangane nezvinodiwa zvakasiyana-siyana zveinjiniya zvinosanganisira madziro ekuchengetedza, macofferdams uye nheyo dzakadzika.

3. Sarudzo dzeKuramba Kuora
Kupera kwepamusoro Kupisa-kunyika, kurapwa kwekudzivirira ngura, uye kugara kwenguva refu kwese kunovandudzwa zvikuru, zvigadzirwa izvi zvinogona kushandiswa munzvimbo dzakaoma dzakadai semvura yegungwa, rwizi, nzvimbo dzine hunyoro hwakawanda nezvimwewo.

4. Kugadzirisa Kuchinjika
Tinotsigira kugadzirisa kwakazara urefu (6m–18m), ukobvu, upamhi, uye kugadziriswa kwakakosha (kucheka, kuboora, kugadzirisa mucheto) kuti zvienderane nezvinodiwa zvepurojekiti neinjiniya.

5. Zvinhu Zvakakura & Kuwanikwa Kwazvo Nekukurumidza
Nematani anopfuura chiuru ezvese zvakagadzirwa, tinovimbisa kuti zvinhu zvinogadzirwa nekukurumidza uye kuti zvinhu zvinogadzirwa zvinogara kwenguva refu, zvichibatsira vatengi kuderedza kunonoka kwemapurojekiti uye kumanikidzwa kwezvinhu zviri mudura.

6. Mitengo Yakananga Yefekitori
Tinopa zvinhu zvakananga kubva kufekitori yedu uye hapana munhu wepakati, izvo zvinotibvumira kukupa mutengo wakanakisa, mhando yakagadzikana uye sevhisi isingadhuri yekutenga zvinhu zvakawanda uye mapurojekiti enguva refu.
