Engineer shovel, txhim kho los ntawm peb tiam ntawm shovel yuav tsum folded ob zaug, tus kov yog daim duab peb sab thiab streamlined, thiab muaj lub zog ntawm duav, de, crowbar (pos), saw, thiab riam. Nyob rau hauv cov nqe lus ntawm ntau lawm technology, high-zoo quenched high-carbon steel yog siv los ua kom muaj zog. , Los tiv thaiv hnav, tiv thaiv corrosion, kub tsis kam. Kuj tseem hu ua sapper shovel. Thaum Tsov Rog Thoob Ntiaj Teb thib ib, cov tub rog German muaj ntau yam khoom siv thiab siv. Tus naj npawb ntawm peb cov tub rog yog qhov loj tshaj ntawm peb cov tub rog ntawm Pawg Neeg Liberation Army. Tom qab disintegration ntawm lub qub Soviet Union, nws yog tam sim no cov tub rog uas muaj coob tus neeg nyob rau hauv lub ntiaj teb no. Hauv keeb kwm, Cov Neeg Liberation Army thawj zaug siv shovels ntawm ib qho loj rau kev ua tub rog hauv peb qhov kev sib ntaus sib tua loj. Ua ntej ntawd, lawv tau tawm tsam guerrillas. Tom qab kev ywj pheej thiab vim muaj keeb kwm keeb kwm, cov koom pheej tau siv cov tswv yim ua tub rog xws li npaj ua tsov rog thiab npaj rau kev tshaib kev nqhis, khawb qhov tob thiab khaws cov nplej, thiab lwm yam, thiab ua tiav ntau qhov kev tsim kho hauv av. Nws tsuas yog tom qab ntawd hais tias lub shovel engineering tau raug suav nrog hauv peb cov tub rog siv tub rog. Nyob rau hauv lub tshav pob ntawm cov cuab yeej, tsis muaj ib tug niaj hnub thiab tiag tiag tub rog engineering duav ua ntej, thiab ib tug heev ntev ntoo kov shovel tau siv.
Kev yug los ntawm ib tiam ntawm kev ua tub rog engineering shovels tuaj yeem hais tau tias yuav tsum tau muaj sia nyob. Cov tub rog pom tias cov ntoo kov ntawm cov shovels ntev dhau lawm, nws tsis yooj yim rau nqa, thiab nws yooj yim los nthuav tawm lub hom phiaj, yog li lawv pom cov ntoo kov luv luv. Tom qab ntawd, txoj kev no maj mam kis mus. Lub sijhawm ntawd, lub tuam tsev logistics tau ntxiv qee qhov kev hloov pauv me me rau lub duav raws li cov lus qhia ntawm ntau cov qub tub rog thiab kev soj ntsuam ntawm ntau lub shovels uas tau siv ntau xyoo. Ua ntej, tus kov ntoo nyob deb ntawm sab saum toj ntawm lub duav. Ib qho me me los ntawm qhov tau qhib thaum uas tig mus rau lub duav saum npoo. Qhov thib ob, raws li kev hnav thiab tsim kua muag ntawm qee qhov siv cov shovels qub, cov ntoo kov tau hloov mus rau hauv cov duab tuab-thin-coarse streamlined, thiab cov qhov me me tau ntxiv rau ntawm ob sab ntawm lub duav saum npoo. Plaub qhov me me yog siv los khi lub duav rau lub hnab taug kev nrog txoj hlua. Nws tsis yooj yim rau poob thaum muaj tub rog ua luam dej, kev tawm dag zog thiab taug kev mus ntev. Lub streamlined ntoo kov yog ntau haum rau tes tuav, thiab nws kuj siv ib txwm ua tub rog ntsuab xim.
