Fortification: Yav tag los thiab tam sim

Txij ancient sij hawm, cov chaw twb ua tau thiab kev tsim kho, uas tso cai rau los mus tiv thaiv lub nroog, lub tsev fuabtais ntawm cov yeeb ncuab tawm tsam. Ncav no hom ntawm cov qauv no yog hu ua fortification. peb nco ntsoov cov zaj lus qhia ntawm keeb kwm, lub ancient hais sib haum ntawm qhia tshwj xeeb uas tsa nyob rau hauv tej thaj chaw deb qhov chaw, piv txwv li, nyob rau hauv lub toj los yog nyob rau hauv lub txuas tus dej ntws. Tom qab ntawd nws tau los ua nrov mus txhim tsa ib ncig ntawm lub forts thiab kev koom artificially tsim teeb meem nyob rau hauv daim ntawv ntawm cov ntoo, kwj deg, cov phab ntsa ntawm ntxhib pob zeb.

yuav tsum muaj wartime

Raws li kev kawm ntawv los ua ntau haib tub rog thiab nquag tsim lub kos duab ua tsov ua rog. Txij li thaum uas lub sij hawm ua lub npe hu cov tub rog tiv thaiv, thaum tsa tag nrho teb strengthening. Vim lub zoo xws li engineering steel tsev ntau npaum siv riam phom thiab tub rog cov khoom, tswj pab tub rog los ua yooj yim, thiab tiv thaiv tiv thaiv yeeb ncuab tawm tsam ua ntau txhim khu kev qha. Niaj hnub nimno tej chaw tiv thaiv yuav ua tau cov nram qab no hom:

• trenches, trenches, uas yog lub tsev rau firing;
• soj ntsuam thiab hais kom posts yog tsim nyog nyob rau hauv thiaj li yuav soj ntsuam koj thiab cov yeeb ncuab txaus qhia thiab hais kom cov tub rog;
• txoj kab txiav Cross, bunkers, shelters tsim los tiv thaiv ob tus neeg thiab tub rog cov khoom;
• kev sib txuas lus trenches, kev soj ntsuam xyuas gallery - qhov no gallery, uas yog underground los yog hauv ib co tsev nrog tus aim los nkaum cov lus.

Fortification, li ntawd, nws yog ib tug txhim khu kev qha txoj kev uas yuav tiv thaiv koj cov tub rog, cov neeg thiab cov khoom siv los ntawm cov yeeb ncuab tawm tsam. Thiab ua ntej lawv muaj pes tsawg twb supplemented nrog rau ntau yam dag obstacles xws li kwj deg, scarps, Contrescarpe, tank obstacles, uas raug xam tias yog ib qho tseem ceeb Cheebtsam ntawm castles, fortresses thiab forts. Tab sis thaum lub sij hawm ob ntiaj teb rog, lub artificially tsim vaj tse raug xam tias yog ywj siab fortified txaus hu ua uas tsis yog-heev obstacles. Tag nrho cov no yog tau muab lub tswvyim ntawm "tej yam yooj yim tiv thaiv", vim hais tias lawv yog ua tsuas thiab sai sai.

Qhib los yog kaw tsim?

Ntawm tus taw tes ntawm view ntawm tus tsim nta ntawm tej lug yuav ua tau qhib los yog kaw. Piv txwv li, kom muaj ib qho qhib kis, trenches, kwj deg, lawv peculiarity yog tias tus tiv thaiv lug yog ntsia tau rau hauv nyias muaj nyias ib qhov chaw, tus nkag mus rau uas yog raug. Nyob rau hauv xws li ib tug tiv thaiv qhov chaw nraim ntawm cov mos txwv, plhaub splinters thiab mines. Fortification ntawm kaw hom yog tsim nyob ib ncig ntawm lub perimeter, uas muab zoo dua tiv thaiv thiab cov pa riam phom thiab nyob rau hauv loj, xws li nuclear riam phom.

Ntawm tus taw tes ntawm view ntawm kev tsim kho tej yam kev mob thiab ua hauj lwm zoo cov yam ntxwv defenses yuav ua tau ntev-lub sij hawm thiab lub teb. Tus thawj yog ua feem ntau nyob rau hauv lub sij hawm ntawm kev kaj siab, thiab rau ib ntev lub sij hawm: mus tsim lawv siv zog cov ntaub ntawv, yog muaj nyob rau hauv cov dej thiab hluav taws xob, raws li nyob rau hauv ib qhov chaw tej zaum cov tub rog yog ib tug ntev lub sij hawm. Nyob rau hauv wartime, feem ntau tsa teb chaw tiv thaiv, uas yog ua los ntawm cov muaj nyob rau ntaub rau ntawm txhais tes (pob zeb, sticks, hav zoov).

Niaj hnub no muaj ntau tshaj designs rau qhov siv thiab ua kev reinforced siv, cov laim ntoom steel, hluavtaws ntaub ntawv yus muaj los ntawm cov cim kev tiv thaiv cov khoom. Ntxiv mus, xws lug yuav muab tau yooj yim thauj nrog cov tub rog.
