Berm - ndi mbali yofunika kwambiri mu Kupanga misewu kapena njira iliyonse

Pali mitundu yosiyanasiyana ya zomangamanga msewu, ntchito zanga mu dzenje lotseguka, komanso kumanga nyumba asilikali kugwiritsa ntchito zina nthaka kuchotsa zipangizo. Kudziko owonjezera si anagwa pansi kulemera yake, ntchito berm.

Kodi berm?

Monga mwana, ana ambiri amakonda kusewera mu sandbox ndi fosholo kukumba maenje ndi mapayi nyumba matope. Kodi misozi yambiri ndi akayamba kuvuta anawona mabowo zomwezi pamene ana ena odzazidwa zoyenda awo mwachisawawa.

Engineering pomanga ngalande kwambiri ndi quarries, mabomba kumafuna kuchotsa zinyalala thanthwe ndi dziko owonjezera m'njira yapadera. Berm - nsanja m'dziko limene limalumikizana m'mphepete m'munsi mwa otsetsereka kumtunda ndi m'mphepete kumtunda kwa recess lapansi.

Chotero nthaka kuchotsa njira limachititsa osati kusintha chitetezo cha anthu ogwira ntchito, komanso kusintha njira mayendedwe a miyala quarries ndi migodi.

Kodi ndi mitundu iti ya berms pali?

Malinga ndi zimene munda berm ntchito, zikhoza kugawidwa mu mitundu ingapo:

• Safety berm. Iyi ndi njira kuteteza mtendere wa mpanda wa anga dzenje lotseguka kapena ku amalowetsa miyala kwaiye pansi phiri. m'lifupi ndi wofanana 1/3 kutalika kwa dzenje. Chotero mtengo limachititsa osati kusamukira zoyendera thanthwe processing exporting, komanso akutumikira kuyeretsa msewu kuchokera zidutswa anayamba kugwa.
• Transport berm. Njira imeneyi yomanga njanji, misewu, ndi zina zotero. E., Kodi iwo agwirizane ntchito nsanja ngalande ndi ledges (cuvette).
• Safety berm. Njira kuteteza zinthu zomwe anayikidwa osiyanasiyana oopsa flammable kapena zachiwawa zinthu.
• Berms ntchito kulumikiza zigawo zosiyana za lotayako, wotchedwa zolumikizira.

Ntchito berms

Ngati inu wofufuza mbiriyakale, wotchuka miyala ya kuti berms ntchito ndi Mfumu Solomo Mines. kupanga diamondi anali amachitika mofanana mu maiko ambiri African. Mwakhama nthaka youma anawomberedwa zigawo, anapanga siteji, kuteteza ndi Matope omwe ankakokoloka anawononga zotheka nthawi ya mvula.

Antchito anayenera pamanja fosholo matani dongo ndi mchenga pofufuza miyala yamtengo wapatali. Mwala amenewa akhoza kudyetsa banja la antchito osauka zaka zisanu.

M'mizinda ikuluikulu, anthu ambiri akukumana nawo mbali imeneyi ya kapangidwe pa Kupanga misewu mu mawonekedwe a ngalande. Chirichonse m'misewu anawatumiza iwo pansi gawo yaulere ya mitengo ndi zitsamba. Mumsewuwu anali yosalala ❖ kuyanika, kupanga mulu wa mamita 1.5. Choncho, madzi ndi chipale sikusokoneza ndimeyi zoyendera.

Pa dongosolo la misewu ayenera bwino kuganizira m'lifupi ndi m'litali mwa njira yatsopano ndi monga berm msewu zatenga malo osachepera 1/3 buku okwana ntchito. Koma magawanidwe amenewa n'komwe ndi kutalika kwa chitunda, ndi akuya ngalande ntchito kukhetsa madzi.

Kwambiri zomangamanga ntchito kale bwino choyalamo ngalande ngalande - chiopsezo osachepera ina zotheka ngozi pa nyengo sili bwino. Chamvula adzakhala nane njira ya, kuchepetsa kolemba.

njanji

Mu moyo wake wonse munthu aliyense kamodzi, koma sitima yapamtunda. Osati ambiri zindikirani kuti pomanga njanji kumafuna khama kwambiri. Ichi ndi chifukwa chakuti, chipongwe, antchito kuganizira zinthu zambiri: nyengo, nthaka, masoka zotheka m'chigawochi.

Roadbed, amene zakhala zikuzunza m'miyoyo pa njanji ndi sleepers, ali mitundu yambiri. Limodzi ndi chitunda mchenga, mwala wosweka kapena miyala kuti asindikize. Kuti berm ntchito mtendere wa kukonza. Pankhani ya katundu wolemera ndipo kugumuka chitunda adzakhala otetezeka, umene uli wofunika kwambiri kwa kayendedwe mosadodometsedwa a sitima.

Berm - ndi mbali ya moyo watsiku ndi tsiku. Anthu okhawo wodziwa zomangamanga ndi kumanga ndi nthawi yoyamba kudziwa kwenikweni kumene izo ntchito.
