Cov qauv siv los txuas cov kav hlau txais xov yog feem ntau hu ua "kev sib txuas lus ntauwd mast," thiab "hlau ntauwd"tsuas yog subclass ntawm "kev sib txuas lus ntauwd mast." Ntxiv rau "hlau pej thuam," "kev sib txuas lus ntauwd mast" kuj suav nrog "mast" thiab "tuab pej thuam." Hlau yees tau muab faib ua lub kaum sab xis steel yees, peb lub raj yees, ib lub raj yees, thiab cov neeg yees. Tsuas yog cov pej thuam guyed, tus so ntawm cov hom tuaj yeem tuav lub cev ncaj nraim ntawm lawv tus kheej. Feem ntau, kev txhawb nqa tus kheej yog sib dhos los ntawmcov kav hlau or kaum steel, nrog qhov siab ntawm ntau tshaj 20 meters mus rau ntau tshaj 100 meters.

Lub kaum sab xis steel yeesyog sib sau ua ke los ntawm lub kaum sab xis steel cov ntaub ntawv, siv bolt kev sib txuas, thiab yooj yim rau kev ua, kev thauj mus los, thiab kev teeb tsa. Lawv muaj tag nrho cov rigidity siab, muaj zog load-bearing muaj peev xwm, thiab mature technical applications. Txawm hais tias lub kaum sab xis steel yees muaj ntau qhov zoo, lawv qhov tsis zoo kuj tseem pom tseeb: lawv nyob thaj tsam loj! Cov hlau loj loj uas sawv ntawm qhov ntawd tso siab rau txhua tus neeg hla. Rau cov neeg nyob ze, lawv tuaj yeem yws vim muaj kev txhawj xeeb txog kev puas tsuaj hluav taws xob. Yog li ntawd, lub kaum sab xis steel ntauwd yog siv nyob rau hauv suburban, county, townships, thiab nyob deb nroog qhov chaw uas tsis muaj kev zoo nkauj thiab tsis muaj nqi av. Cov cheeb tsam no feem ntau muaj cov neeg siv tsawg dua thiab tsim nyog rau kev siv dav dav siv cov pej thuam siab.

Ntauwd lub cev ntawm apeb-tube ntauwdyog ua los ntawm steel kav, nrog peb lub ntsiab steel kav cog rau hauv av raws li lub moj khaum, supplemented los ntawm ib co kab rov tav thiab kab pheeb ces kaum steel cov ntaub ntawv rau fixation. Piv nrog rau lub kaum sab xis steel yees, qhov ntoo khaub lig ntawm peb lub raj ntauwd yog daim duab peb sab, thiab lub cev yog slimmer. Yog li ntawd, nws muaj cov qauv yooj yim, cov khoom siv tsawg dua, kev tsim kho yooj yim, thiab cov hneev taw me me, ua rau nws raug nqi ntau dua. Txawm li cas los, nws muaj nws drawbacks: qis zog thiab unattractive tsos. Yog li ntawd, peb-tube yees kuj tsim nyog rau cov cheeb tsam uas tsis muaj kev xav zoo nkauj, xws li suburban, county, townships, thiab nyob deb nroog, nrog cov pej thuam siab qis dua lub kaum sab xis steel yees.

A telecom monopole ntauwdtsuas yog cog cov yeeb nkab tuab tuab ntsug, ua kom yooj yim thiab zoo nkauj, tuav tus hneev taw me me, thiab ua kom sai. Txawm li cas los xij, nws muaj nws qhov tsis zoo: tus nqi siab, kev txhim kho siab, kev thauj mus los nyuaj vim muaj cov khoom loj dua, thiab kev tswj tsis tau zoo vim muaj ntau cov welds. Txawm hais tias cov teeb meem no, ib leeg-tub yees muaj ntau yam kev siv, tsim nyog rau thaj chaw hauv nroog, thaj chaw nyob, tsev kawm qib siab, thaj chaw lag luam, thaj chaw zoo nkauj, chaw ua si, thiab kev tsheb ciav hlau.

A guyed pej thuamyog ib lub pej thuam uas tsis muaj zog heev uas tsis tuaj yeem sawv ntawm nws tus kheej thiab yuav tsum muaj ob peb tus txiv neej nyob ntawm qhov yuav tsum tau kho rau hauv av. Nws muaj qhov zoo ntawm kev pheej yig, hnav, thiab yooj yim rau nruab. Txawm li cas los xij, nws qhov tsis zoo suav nrog thaj chaw loj, kev cia siab tsis zoo, tsis muaj peev xwm thauj khoom tsis muaj zog, thiab nyuaj rau kev teeb tsa thiab kev saib xyuas ntawm cov txiv neej hlau. Yog li ntawd, guyed towers feem ntau yog siv nyob rau hauv qhib roob thiab nyob deb nroog.

Muab piv rau cov yees saum toj no, cov neeg yees tsis tuaj yeem sawv ntawm nws tus kheej thiab xav tau cov txiv neej cov xov hlau rau kev txhawb nqa, yog li lawv raug hu ua "cov pej thuam tsis yog tus kheej," thaum lub kaum sab xis steel yees, peb lub raj yees, thiab ib lub raj yees yog tag nrho. “txhawb nqa tus kheej”
