Mzere wapamwamba umatanthawuza mzere wotseguka pamwamba womwe umakhazikitsidwa pansi, womwe ndi chingwe chamagetsi chamagetsi chomwe chimakhazikitsidwa pa nsanja ya pole ndi zotetezera ndi zopangira mphamvu.Amapangidwa ndi waya ndi pansi waya (pamwamba pansi waya), nsanja, insulator, hardware, ndi zigawo zina za nsanja maziko, nangula ndi pansi chipangizo, waya amapangidwa ndi zitsulo zabwino conductive, pali wandiweyani gawo okwanira (kuti kusunga kachulukidwe otaya bwino) ndi utali wozungulira lalikulu la kupindika (kuchepetsa corona kumaliseche) ndi kopitilira muyeso-mkulu voteji kufala ndithudi ntchito kugawanika kondakitala;Chingwe cha insulator chimapangidwa ndi chingwe chimodzi choyimitsidwa (kapena bar) cha insulator, chomwe chiyenera kukwaniritsa zofunikira za mphamvu zotetezera ndi mphamvu zamakina, ndipo chiwerengero cha insulators mu chingwe chilichonse chimatsimikiziridwa ndi msinkhu wa voteji.Mitengo ndi nsanja, zomwe nthawi zambiri zimapangidwa ndi chitsulo kapena konkriti, ndiye njira zazikulu zothandizira mizere yopatsira pamutu ...

Timawona mizere yapamwamba nthawi zambiri imayikidwa pa waya wotseguka pansi, nthaka imakhala ndi kutalika kwinakwake, koma, tsopano, sitikudziwa kuyambira liti, mizere yapamwamba imayamba kuzimiririka kuchokera kumalingaliro athu, kutayika sikutanthauza kuti palibe pamwamba. mizere apa, ndithudi, koma mizere iyi pamwamba pa nthaka, ndipo inakwiriridwa mu nthaka.Kodi chikuchitika ndi chiyani pano?Ndi ubwino wanji kuti mzere wa pamwamba upite pansi?Chotsatira, kuti ndilankhule nanu za mzere wapamwamba mu chidziwitso chokhudzana ndi nthaka, ndikuyembekeza kuti mutha kumvetsetsa.

Tisanayambe kulankhula za ubwino wa mlengalenga mzere pansi, choyamba tiyang'ane nkhani zingapo nkhani: Tongzhou District boma lakale kumadzulo gawo, Songzhuang Road, Defense South Road Defense North msewu, Hongyun Science ndi Technology Park msewu ndi ena 83 misewu. , "njira yolumikizirana ndi ndege pansi" pamisewu iyi, kutalika kwa msewu ndi makilomita 45.398, ndalama zomwe polojekitiyi ikuyembekezeka: 137,425,900;Msewu wa Baotou Industrial Road kumwera kwa msewu waukulu (kuchokera ku Dongmen Street kupita ku Zhanbei Road) uyeneranso kulowa pansi;Shanghai Xuhui ndi Changning, Sichuan, akugwiranso ntchito limodzi kukankhira chingwe chapamwamba pansi ndi kugwirizanitsa ntchito……

Nanga n’cifukwa ciani mawaya apamtunda amapita pansi?Ndiye ubwino wolowera pamzere wapamwamba ndi wotani?Tiyenera kumvetsa chifukwa mzere pamwamba pa nthaka, zikunenedwa kuti malo ambiri ayenera pamwamba mzere mu nthaka, chifukwa mzere pamwamba n'zosavuta kukhudzidwa ndi zinthu zachilengedwe, kuti mizere ya malo amenewa nthawi zambiri magetsi. "sitoloyo sayesa kugwiritsa ntchito zida zamphamvu kwambiri", kuopa kugunda kwa bingu ndi mvula, zomwe zimabweretsa ovulala.Komabe, pambuyo pa mzere wopita pamwamba pa nthaka, sizili zofanana, kupyolera mu kukonzanso, msewu kumbali zonse ziwiri za zatsopano, zomwe zimathandizira kupititsa patsogolo chilengedwe cha mizinda;Mogwira pewani kugawa maukonde kulephera chifukwa cha nyengo yoipa ndi kuwonongeka kunja, kuchepetsa kwambiri chiwerengero ndi kukula kwa mphamvu kulephera, pamene kuwongolera chitetezo ndi kudalirika gululi mphamvu, amene ndi phindu lalikulu kwa ife.
