Umnatha okhuselayo osetyenziselwa ukuthintela ukuphosa izinto kwiibhulorho ubizwa ngokuba ngumnatha ochasene nokuphosa ibhulorho. Kuba isoloko isetyenziswa kwii-viaducts, ikwabizwa ngokuba yi-viaduct anti-throwing net. Umsebenzi wayo ophambili kukuyifakela kwiindlela zikamasipala, iindawo zokuwela uhola wendlela, iindawo zokudlula zikaloliwe, iindawo ezidlulayo, njl. Le ndlela inokuqinisekisa ukuba abahambi ngeenyawo kunye nezithuthi ezidlula ngaphantsi kwebhulorho aziyi kwenzakala. Kwimeko enjalo Phantsi kweemeko ezinjalo, ukusetyenziswa kweminatha echasene nokujula kwebhulorho kuyanda.
Ngenxa yokuba umsebenzi wayo ukhusela, umnatha ochasene nokuphosa ibhuloho kufuneka ube namandla aphezulu, amandla okulwa ne-corrosion enamandla kunye ne-rust. Ngokuqhelekileyo, ukuphakama komnatha ochasene nokuphosa ibhulorho phakathi kwe-1.2-2.5 yeemitha, kunye nemibala ecebileyo kunye nokubonakala okuhle. Yihombise imeko-bume yedolophu.
Iimpawu eziqhelekileyo zebhulorho echasene nokuphosa umnatha:
(1) Izinto eziphathekayo: ucingo lwentsimbi ephantsi yekhabhoni, umbhobho wentsimbi, uphothiweyo okanye udityaniswe.
(2) Imilo yeMesh: isikwere, irhombus (intsimbi yentsimbi).
(3) Iimpawu zeMesh: 60×50mm, 50×80mm, 80×90mm, 70×140mm, njl.
(4) Ubungakanani bomngxuma we-Sieve: umgangatho oqhelekileyo we-1900 × 1800mm, umda wobude obungalinganiyo ngu-2400mm, umda wobude ngu-3200mm, kwaye unokwenziwa ngokwezifiso ngokuhambelana neemfuno zabathengi.
Izinto eziluncedo kwibhulorho echasene nokuphosa umnatha:
(1) Ibhulorho yokuchasana nokuphosa inetha kulula ukuyifaka, inoveli imile, intle kwaye ihlala ixesha elide, kwaye inokhuseleko oluphezulu.
(2) Ibhulorho yokuchasana nokuphosa inetha kulula ukuyiqhawula kunye nokudibanisa, ihlaziywa, inokuphinda isetyenziswe, kwaye inokulungiswa ngokukhululekileyo ngokweemfuno.
(3) Iminatha echasene nokuphosa ibhulorho ayinakusetyenziselwa kuphela ukukhusela iibhulorho, kodwa nakwiindlela ezinkulu, oololiwe, izikhululo zeenqwelomoya, iipaki zemizi-mveliso, iindawo zophuhliso lwezolimo nezinye iindawo.
