Dab tsi yog lub tsev cable?
Guyed Ntauwd Kev Tsim Kho Lub Tsev Guyed yog lub teeb rau lub luag haujlwm hnyav kev sib txuas lus ntauwd tsim los ntawm cov pas nrig ncaj uas tau teem rau hauv daim duab peb sab tab sis txhawb nqa los ntawm cov xov hlau ntawm txhua lub kaum ntse ntse. Rub-cov xov hlau tshwj xeeb yog siab, txog li 2,000 ko taw, thiab feem ntau yog siv los ua kom cov kav hlau txais xov siab siab saum av kom muaj zog dua lub teeb liab thiab txais xov tooj ntawm tes.
Ntxiv nrog rau kev siv xov tooj ntawm tes, lawv kuj tuaj yeem siv rau kev siv xov tooj cua thiab TV. Lawv zoo tagnrho rau cov neeg siv khoom nyob deb nroog uas xav tau qhov siab tshaj plaws ntawm tus nqi pheej yig.
Ib nrab pylons thiab ntxiv pylons
Ib feem ntawm cov pej thuam muaj xws li cov masts nyob rau sab saum toj ntawm qhov ruaj khov, tus kheej - muaj cov qauv. Cov hlau tuaj yeem txuas rau sab saum toj ntawm cov qauv lossis rau hauv av.
Ib tug txiv leej tub ntxiv ntauwd ntxiv kev txhawb nqa hlau. Lawv tuaj yeem txuas tau ib ntus rau kev ruaj ntseg ntxiv (xws li thaum lub sijhawm tsim kho) lossis tsuas yog nyob rau hauv ib qho kev taw qhia los txhawb unidirectional shear stress.
Ib qho piv txwv ntawm qhov no tej zaum yuav yog ib tug ncej tom kawg ntawm ib txoj kab hluav taws xob uas xaus los yog nqes mus rau lwm qhov. Tsuas yog tib neeg nyob rau hauv ib qho kev taw qhia yog xav tau los txhawb nqa qhov tsis sib npaug ntawm cov kab hluav taws xob hauv lwm qhov kev taw qhia.
lwm hom pej thuam
Ntxiv nrog rau cable ntauwd, lwm yam kev hloov pauv tuaj yeem siv tau nyob ntawm qhov project yuav tsum tau ua. Cov no suav nrog:
monopole ntauwd
Ib leeg tubular mast muaj xws li hom cellular ntauwd; vim qhov tsis ruaj khov qhia los ntawm kev siv ib lub mast, cov qauv no tsis pub tshaj 200 feet hauv qhov siab. Ib qho txiaj ntsig ntawm hom pej thuam no yog tias nws yuav tsum muaj qhov chaw me me hauv pem teb los txhim kho, thiab lub kav hlau txais xov tuaj yeem yooj yim mounted sab nraum lub mast.
lattice pej thuam
Lattice towers, also known as "free-standing towers," are usually made of steel and are triangular or square in shape. These towers generally offer the most stability and flexibility compared to other cellular tower types.
Stealth Ntauwd
Stealth yees tuaj yeem siv los ua kom tau raws li kev cai zoning. Lawv kim dua lwm cov yees vim lawv xav tau cov khoom siv ntxiv los tsim kom pom qhov zais zais. Lawv qhov me me feem ntau ua rau lawv tsis tshua muaj txiaj ntsig.
Have you ever seen a painted metal tree standing tall on the side of a highway? This is a familiar example of a stealth tower. This type of structure is used whenever a tower might need to be hidden from view. They're designed to ensure they blend in with their surroundings, as many see exposed cell towers as ugly, or an intrusion. These towers can take the shape of many other objects, such as signs, flagpoles, and even cacti!
