Segment sib dhos thiab kev sib txuas ntawm corrugated culvert yeeb nkab

Cov sib dhos corrugated culvert yeeb nkabyog ua los ntawm ob peb daim ntawm corrugated daim hlau tsau nrog bolts thiab ceev, nrog nyias daim hlau, lub teeb yuag, yooj yim thauj thiab khaws cia, txheej txheem kev tsim kho yooj yim, yooj yim rau nruab rau ntawm qhov chaw, daws qhov teeb meem ntawm kev puas tsuaj ntawm cov choj thiab cov yeeb nkab culvert. cov qauv hauv cov chaw txias, nrog rau kev sib dhos ceev, lub sijhawm siv sijhawm luv thiab lwm yam zoo.

Cov yeeb nkab ntu sib dhos thiab kev sib txuas ntawm cov corrugated sib dhoscev cult
1, Kev npaj ua ntej: xyuas qhov flatness, qhov siab ntawm hauv qab ntawm cov kav dej culvert thiab teeb tsa ntawm lub hauv paus foreseen koov, txiav txim siab txoj hauj lwm, nruab nrab axis thiab nruab nrab ntawm cov yeeb nkab culvert.
2 、 Sib sau ua ke hauv qab phaj: nqa qhov chaw nruab nrab thiab nruab nrab raws li qhov kev siv, thawj lub phaj corrugated yog positioned, thiab txuas mus rau ob sab nrog qhov no raws li qhov pib taw tes kom txog rau thaum ob kawg ntawm culvert yeeb nkab ntshuam thiab xa tawm; lub phaj thib ob yog muab tso rau sab saum toj ntawm thawj tus (phaj ntev yog 50mm), thiab ua raws li qhov sib txuas. Lub ntsia liaj qhov rooj tau muab tso rau hauv lub qhov ntsia hlau los ntawm sab hauv mus rau sab nraud, sab nraud ntawm lub tshuab ntxhua khaub ncaws, ua ntej zawm cov txiv ntoo nrog lub qhov (socket) wrench.
3, Sib dhos lub nplhaib nplhaib los ntawm hauv qab upwards nyob rau hauv lem: lub puab tsaig ib feem ntawm lub sab sauv phaj npog lub sab phaj, circumferential kev twb kev txuas siv stepped, uas yog, lub Upper ob boards txuas cov stacked seams thiab cov nram qab no ob boards ntawm stacked seam misalignment, txuas lub stacked seams misalignment, txuas lub qhov tam sim tom qab cov bolts tau ntxig los ntawm sab hauv tawm mus rau hauv cov ntsia hlau qhov, pre-tighten cov txiv ntseej nrog lub qhov (socket) wrench.
4, txhua 'meter' ntev sib sau ua ke tom qab molding, los txiav txim seb cov duab ntawm cov ntoo khaub lig-section, kom ua tau raws li cov qauv thiab tom qab ntawd txuas ntxiv mus sib sau ua ke, tsawg dua tus qauv yuav tsum tau hloov kho raws sijhawm. Circumferential los ua ke rau lub nplhaib thaum lub nplhaib ua ke, kev txiav txim siab ntawm cov duab sib dhos, siv qhov chaw khi pas nrig, kho cov ntsia hlau ua ntej tensioning, assembling corrugated yeeb nkab.

5 、 Tom qab tag nrho cov culvert yeeb nkab sib sau ua tiav, siv qhov ruaj khov-torque chav ciaj ntswj kom nruj tag nrho cov bolts raws li lub zog ntawm 135.6 ~ 203.4Nm, nyob rau hauv kev txiav txim ntawm ib ntus, tsis txhob plam, thiab hauv qab bolts yog cim nrog liab pleev xim tom qab zawm. Tag nrho cov bolts (xws li longitudinal thiab circumferential pob qij txha) yuav tsum tau nruj me ntsis ua ntej backfilling los xyuas kom meej tias cov overlapping qhov chaw ntawm lub corrugation yog nruj nreem nested ua ke.

6. Txhawm rau kom ntseeg tau tias qhov yuav tsum tau muaj ntawm lub bolt torque lub sijhawm ua tiav, random xaiv 2% ntawm cov bolts ntawm cov pob qij txha ntev ntawm cov qauv ua ntej backfilling, thiab ua ib qho kev sim ua piv txwv nrog lub torque ciaj ntswj. Yog hais tias ib tug bolt torque tus nqi ntau yam tsis ncav cuag tus nqi yuav tsum tau, ces 5% ntawm tag nrho cov bolts nyob rau hauv longitudinal thiab circumferential pob qij txha yuav tsum tau coj mus kuaj. Yog hais tias tag nrho cov saum toj no sampling xeem ua tau raws li qhov yuav tsum tau, lub installation yog suav hais tias txaus siab. Txwv tsis pub, nws yuav tsum tau rov kuaj xyuas seb qhov ntsuas qhov ntsuas qhov ntsuas puas ua tau raws li qhov yuav tsum tau ua.
7 、 Tom qab cov bolts ntawm lub puab tsaig sib koom ua ke ntawm lub nplhaib sab nraud yog nruj thiab ua tau raws li qhov yuav tsum tau ua, txhawm rau tiv thaiv cov dej ntws ntawm cov seams ntawm corrugated steel phaj thiab ntsia liaj qhov rooj qhov, tshwj xeeb sealing cov ntaub ntawv yog siv los kaw cov phaj steel thiab ntsia liaj qhov rooj. lub qhov los tiv thaiv dej seepage ntawm corrugated phaj sib koom.
8, tom qab kev teeb tsa tiav, nyob rau hauv cov yeeb nkab sab hauv thiab sab nraum lub teeb txhuam ob asphalt, asphalt tuaj yeem kub asphalt lossis emulsified asphalt, asphalt txheej yuav tsum tsawg dua li tag nrho cov tuab ntawm 1 hli.
