Segment musangano uye kubatanidzwa kwe corrugated culvert pipe

Vakaungana marata culvert pipeinogadzirwa nezvidimbu zvinoverengeka zvemarata emarata akaiswa mabhaudhi nenzungu, ane mahwendefa matete, uremu huremu, nyore kutakurwa uye kuchengetwa, nzira yekuvaka iri nyore, iri nyore kuisirwa panzvimbo, kugadzirisa dambudziko rekuparadzwa kwemabhiriji uye pombi culvert zvivakwa munzvimbo dzinotonhora, nekukurumidza kusangana, nguva pfupi yekuvaka uye zvimwe zvakanakira.

Pipe chikamu gungano uye kubatana kwevakaungana makoraculvert pipe
1, Pre-kuvaka kugadzirira: tarisa flatness, kukwidziridzwa kwepazasi pepombi pombi uye kuseta kwechigadziko chakafanooneswa arch, sarudza chinzvimbo, yepakati axis uye midpoint ye culvert pombi.
2, Kuunganidza ndiro yepasi: tora akisi yepakati nepakati sereferensi, ndiro yekutanga yemarara yakamira, uye inotambanukira kumativi ese neino sepokutangira kusvika kumigumo miviri yepombi yekupinza uye kutumira kunze kwenyika; ndiro yechipiri yakarongedzwa pamusoro peyokutanga (kureba kwemakumbo ndeye 50mm), uye inopindirana nemakomba ekubatanidza. Iyo bhaudhi inopinzwa mugomba rekupura kubva mukati kuenda kunze, kune yakatarisana neseti ye washers nati, pre-kusimbisa nati nechipanera chesoketi.
3, Kuunganidza mhete yemhete kubva pasi zvichikwira zvichichinjana: chikamu cheplate yepamusoro yakavhara ndiro yepasi, circumferential connection ichishandisa yakatsika, kureva kuti, mapuranga maviri epamusoro anobatanidza seams akaturikidzana uye mapuranga maviri anotevera eakarongedzerwa seam misalignment, achibatanidza akaturikidzana seams kusarongeka, kubatanidza maburi kubva mukati maburi kunze kwekunze. pre-simbisa nati nechipanera chesokisi.
4, kureba kwemamita imwe neimwe yakaunganidzwa mushure mekuumbwa, kuti ione chimiro chemuchinjikwa-chikamu, kuti isangane nemiyero uye ienderere mberi kuungana, zvishoma kudarika chiyero chinofanira kugadziriswa panguva yakakodzera. Circumferential musangano kune mhete kana mhete pamwe chete, kutsunga kwe-cross-sectional shape, uchishandisa positioning tie tsvimbo yakagadziriswa, gadzirisa mabhaudhi ekutanga, kuunganidza pombi yakasvibiswa.

5, Mushure mokunge pombi yose yakabatanidzwa yapera, shandisa fixed-torque steam wrench kuti usimbise mabhoti ose maererano ne torque ye 135.6 ~ 203.4Nm, maererano nekutevedzana, kwete kupotsa, uye mabhoti epasi akanyorwa nependi tsvuku mushure mekusimbisa. Ese mabhaudhi (kusanganisira longitudinal uye circumferential majoini) anofanirwa kusimbiswa asati adzoreredza kumashure kuti ave nechokwadi chekuti zvikamu zvinopindirana zvecorrugation zvakabatanidzwa zvakasimba pamwechete.

6. Kuti uone kuti kukosha kunodiwa kwebhoti torque nguva kunowanikwa, sarudza 2% yemabhoti pamajoini ehurefu pachigadziro usati wadzorera shure, uye ita sampling test ine nguva dzose torque wrench. Kana chero bhaudhi torque kukosha renji isingasviki kukosha kunodiwa, ipapo 5% yemabhaudhi ese mulongitudinal uye circumferential majoini anofanira kutorwa sample. Kana ese ari pamusoro apa sampling bvunzo akazadzisa zvinodiwa, kuiswa kunoonekwa sekugutsa. Zvikasadaro, inofanirwa kuongororwazve kuti ione kana iyo yakayerwa torque kukosha inosangana nezvinodiwa.
7, Mushure mekunge mabhaudhi ari pamakumbo akabatana echindori chekunze asimbiswa uye anosangana nezvinodiwa, kuitira kudzivirira mvura kuti isapinda pamipendero yendiro yesimbi ine marata nemakomba ebhaudhi, zvinhu zvakakosha zvekuisa chisimbiso zvinoshandiswa kuvhara simbi yendiro yesimbi uye maburi ebhaudhi kudzivirira kubuda kwemvura pajoinhi remarata.
8, mushure mekugadzwa kwapera, mupombi mukati uye kunze kweyunifomu bhurashi maviri asphalt, asphalt inogona kupisa asphalt kana emulsified asphalt, asphalt layer inofanira kunge iri pasi pehupamhi hwese hwe1mm.
