Nzira yekuwedzera sei hupenyu hwesevhisi yekuvhara manhole?

Kudzivirira nodular cast iron manhole cover kubva pakukukurwa pasi pevhu uye kuwedzera hupenyu hwesevhisi yepombi network, iyo yekunze yepamusoro yenodular cast iron manhole kavha inofanira kuputirwa nejira reasphalt pendi, uye yozorongedzerwa mudura. Kuti uwedzere kusimbaradza kusadzivirirwa kwezvivharo zvesimbi yakakandwa, mugero wesimbi wakakandwa vanogadzira vanofanirwa kupfapfaidza zinc pamusoro pekunze kwe ductile iron manhole anovhara. Isu tinokwanisa kuita kwakasiyana-siyana kwepamusoro kurapwa kwesimbi yakakandwa manhole inovhara.

Zvakadai se epoxy resin pendi, inopisa dip galvanizing uye zvichingodaro Cast iron munhoro inovhara ngura; Dzimwe nguva pachava ne ngura pamberi kana panguva yekugadzirwa kwesimbi yakakandwa manhole anovhara, izvo zvinoratidza kuti chitarisiko chakasvibiswa zvakanyanya. Kavha yegomba ine ngura inofanira kukwenenzverwa uye kupfurwa kuti ibvise ngura, uye nzvimbo yacho inofanira kuongororwa isati yabuda mufekitari.
