Kev sib dhos ua ntu thiab kev txuas ntawm cov yeeb nkab corrugated culvert

Cov khoom sib dhos ua ke corrugated yeeb nkabyog ua los ntawm ntau daim ntawm cov phaj corrugated kho nrog bolts thiab txiv ntoo, nrog cov phaj nyias, lub teeb yuag, yooj yim thauj mus los thiab khaws cia, cov txheej txheem tsim kho yooj yim, yooj yim rau kev teeb tsa ntawm qhov chaw, daws qhov teeb meem ntawm kev puas tsuaj ntawm cov choj thiab cov yeeb nkab culvert qauv hauv thaj chaw txias, nrog kev sib dhos ceev, lub sijhawm tsim kho luv luv thiab lwm yam zoo.

Kev sib dhos thiab kev sib txuas ntawm cov yeeb nkab corrugatedcov yeeb nkab culvert
1. Kev npaj ua ntej kev tsim kho: xyuas seb lub raj xa dej puas tiaj tiaj, qhov siab ntawm qab ntawm lub raj xa dej thiab qhov teeb tsa ntawm lub hauv paus uas pom tseeb, txiav txim siab qhov chaw, qhov chaw nruab nrab thiab qhov nruab nrab ntawm lub raj xa dej.
2. Sib dhos lub phaj hauv qab: siv lub axis nruab nrab thiab qhov nruab nrab ua qhov siv, thawj lub phaj corrugated raug tso rau, thiab nthuav mus rau ob sab nrog qhov no ua qhov pib kom txog thaum ob qho kawg ntawm cov yeeb nkab culvert ntshuam thiab xa tawm; lub phaj thib ob raug teeb tsa rau saum thawj lub (ntev yog 50 hli), thiab sib dhos nrog cov qhov txuas. Lub bolt raug ntxig rau hauv lub qhov ntsia hlau los ntawm sab hauv mus rau sab nraud, sab nraud ntawm cov txiv ntoo washer, ua ntej-nruj lub txiv ntoo nrog lub wrench socket.
3. Sib dhos lub nplhaib los ntawm hauv qab mus rau saum toj: ib feem ntawm lub phaj sab saud uas npog lub phaj qis, kev sib txuas ntawm txoj kab uas hla siv cov kauj ruam, uas yog, ob lub rooj tsavxwm sab saud txuas cov seams sib dhos thiab ob lub rooj tsavxwm tom qab ntawm cov seams sib dhos tsis sib xws, txuas cov seams sib dhos tsis sib xws, txuas cov qhov tom qab cov bolts raug ntxig los ntawm sab hauv mus rau hauv cov qhov ntsia hlau, ua ntej-nruj lub txiv ntoo nrog lub wrench socket.
4, txhua lub 'meter' ntev sib sau ua ke tom qab molding, los txiav txim siab seb qhov seem ntawm qhov seem yog dab tsi, kom ua tau raws li cov qauv thiab tom qab ntawd txuas ntxiv sib sau ua ke, tsawg dua li tus qauv yuav tsum tau kho raws sijhawm. Thaum lub nplhaib sib dhos ua ke, txiav txim siab seb qhov seem ntawm qhov seem yog dab tsi, siv txoj hlua khi kom ruaj khov, kho cov ntsia hlau ua ntej, thiab sib dhos cov yeeb nkab corrugated.

5. Tom qab ua tiav tag nrho cov yeeb nkab culvert, siv lub wrench steam torque kom nruj tag nrho cov bolts raws li lub zog ntawm 135.6 ~ 203.4Nm, raws li qhov kev txiav txim, kom tsis txhob nco qab, thiab cov bolts hauv qab yog cim nrog xim liab tom qab nruj. Txhua lub bolts (xws li cov pob qij txha longitudinal thiab circumferential) yuav tsum tau nruj ua ntej rov qab filling kom ntseeg tau tias cov khoom sib tshooj ntawm cov corrugation tau sib sau ua ke nruj.

6. Yuav kom paub tseeb tias tus nqi ntawm lub zog bolt torque tau raws li qhov xav tau, xaiv 2% ntawm cov bolts ntawm cov pob qij txha ntev ntawm cov qauv ua ntej rov qab los, thiab ua qhov kev sim kuaj nrog lub wrench torque tas li. Yog tias muaj qhov ntau ntawm lub zog bolt torque tsis ncav cuag tus nqi xav tau, ces 5% ntawm tag nrho cov bolts hauv cov pob qij txha ntev thiab circumferential yuav tsum tau kuaj. Yog tias tag nrho cov kev sim kuaj saum toj no ua tau raws li qhov yuav tsum tau ua, qhov kev teeb tsa raug suav hais tias txaus siab. Txwv tsis pub, nws yuav tsum tau rov kuaj dua kom paub tseeb tias tus nqi torque ntsuas tau ua tau raws li qhov yuav tsum tau ua.
7, Tom qab cov ntsia hlau ntawm lub pob qij txha ntawm lub nplhaib sab nraud raug nruj thiab ua tau raws li qhov yuav tsum tau ua, txhawm rau tiv thaiv dej ntws ntawm cov seams ntawm corrugated steel phaj thiab bolt qhov, cov ntaub ntawv sealing tshwj xeeb yog siv los kaw cov hlau phaj sib koom ua ke thiab bolt qhov kom tiv thaiv dej ntws ntawm corrugated phaj sib koom ua ke.
8, tom qab kev teeb tsa tiav lawm, hauv cov yeeb nkab sab hauv thiab sab nraud ob lub txhuam asphalt sib xws, asphalt tuaj yeem yog asphalt kub lossis emulsified asphalt, asphalt txheej yuav tsum tsawg dua 1 hli tag nrho cov tuab.
