Kusonkhana kwagawo ndi kulumikiza chitoliro cha malata

Osonkhana chitoliro cha malataamapangidwa ndi zidutswa zingapo za malata okhazikika ndi mabawuti ndi mtedza, ndi mbale woonda, kulemera kuwala, zosavuta kunyamula ndi kusungidwa, njira yosavuta yomanga, yosavuta kuyika pa malo, kuthetsa vuto la kuwononga milatho ndi chitoliro culvert. zomanga m'madera ozizira, ndi msonkhano wachangu, nthawi yochepa yomanga ndi ubwino wina.

Chitoliro gawo msonkhano ndi kugwirizana kwa corrugated anasonkhanabomba la culvert
1, Kukonzekera koyambirira: fufuzani kusalala, kukwera kwa pansi pa chitoliro cha culvert ndi kukhazikitsidwa kwa maziko omwe adawoneratu Chipilala, dziwani malo, olamulira apakati ndi pakati pa chitoliro cha culvert.
2, Kusonkhanitsa mbale pansi: kutenga pakati olamulira ndi midpoint monga buku, mbale malata woyamba ali pabwino, ndipo chimafikira mbali zonse ndi ichi monga poyambira mpaka malekezero awiri a culvert chitoliro kuitanitsa ndi katundu; mbale yachiwiri imayikidwa pamwamba pa yoyamba (kutalika kwa lap ndi 50mm), ndikugwirizana ndi mabowo ogwirizanitsa. The bawuti anaikapo mu dzenje wononga kuchokera mkati mpaka kunja, mbali ina ya ya washers nati, chisanadze kumangitsa mtedza ndi zitsulo wrench.
3, Kusonkhanitsa mphete kuchokera pansi mmwamba motsatira: chilolo mbali ya mbale chapamwamba kuphimba mbale m'munsi, kugwirizana circumferential ntchito anaponda, ndiye chapamwamba matabwa awiri kulumikiza seams zakhala zikuzunza m'miyoyo ndi matabwa awiri otsatirawa za zakhala zikuzunza m'miyoyo misalignment msoko, kulumikiza misalignment yosanjikizana, kulumikiza mabowowo pambuyo poti mabawuti alowetsedwe kuchokera mkati kupita kumabowo omangira, kulimbitsa natiyo ndi socket wrench.
4, kutalika kwa mita iliyonse kumasonkhanitsidwa pambuyo pa kuumba, kuti mudziwe mawonekedwe a gawo la mtanda, kuti mukwaniritse miyezo ndikupitiriza kusonkhana, zosachepera zomwe ziyenera kusinthidwa panthawi yake. Circumferential msonkhano mphete pamene mphete pamodzi, kutsimikiza kwa mawonekedwe mtanda-gawo, ntchito malo tayi ndodo zokhazikika, kusintha mabawuti chisanadze tensioning, kusonkhanitsa malata chitoliro.

5, Pambuyo pa kusonkhanitsa chitoliro chonse cha culvert, gwiritsani ntchito wrench ya nthunzi yokhazikika kuti mumitse mabawuti onse molingana ndi makokedwe a 135.6 ~ 203.4Nm, motsatana, kuti musaphonye, ​​ndipo mabawuti apansi amalembedwa ndi ofiira. penti pambuyo kumangitsa. Maboti onse (kuphatikiza ma longitudinal ndi ma circumferential joints) akuyenera kumangidwa asanabwezere kumbuyo kuti awonetsetse kuti magawo omwe akudutsana a corrugation amalumikizidwa molimba.

6. Kuti muwonetsetse kuti mtengo wofunikira wa mphindi ya bolt ukukwaniritsidwa, sankhani 2% ya ma bolts pamalumikizidwe aatali pamapangidwewo musanabwezere, ndikuyesa sampuli ndi wrench yokhazikika. Ngati mtundu uliwonse wa torque wa bawuti sufika pamtengo wofunikira, ndiye kuti 5% ya ma bolts onse olumikizana nthawi yayitali komanso ozungulira ayenera kutsatiridwa. Ngati mayesero onse omwe ali pamwambawa akukwaniritsa zofunikira, kuyikako kumaonedwa kuti n'kokwanira. Kupanda kutero, iyenera kuyesedwanso kuti muwone ngati mtengo wa torque woyezedwa ukukwaniritsa zofunikira.
7, Pambuyo mabawuti pa chilolo olowa mphete yakunja ndi olimba ndi kukwaniritsa zofunika, pofuna kuteteza madzi seepage pa seams malata mbale zitsulo ndi mabowo bawuti, zipangizo kusindikiza wapadera ntchito kusindikiza zitsulo mbale olowa ndi bawuti. mabowo kuti madzi asalowe m'malo olumikizirana mbale.
8, pambuyo unsembe anamaliza, mu chitoliro mkati ndi kunja yunifolomu burashi awiri phula, phula akhoza otentha phula kapena emulsified phula, phula wosanjikiza ayenera kukhala zosakwana makulidwe okwana 1mm.
