(1) Ukuphakama kokuvalwa kokuma phansi ngokuphelele akufanele kudlule ama-35m. Lapho ukuphakama kuphakathi kuka-35 no-50m, kufanele kuthathwe izinyathelo zokulayisha. Lapho ukuphakama kukhulu kune-50m, kufanele kuthathwe izindlela zokulayisha nezinhlelo ezikhethekile kufanele zithathwe.
Yenza izimpikiswano zesazi.
. Isisekelo siyoqina ngokhonkolo obukhulu obukhulu be-C25 ngokhonkolo, bese isisekelo noma i-pad sizosethwa ezansi kwesigxobo. Ipuleti elisekelayo kufanele libe ngobude obuhlukile
Amabhodi asekelwa ngokhuni anama-spans angaphansi kwama-2, ukushuba okungaphansi kwama-50mm, nobubanzi hhayi ngaphansi kwama-200mm.
. Lapho isisekelo se-vertical pole singekho ekuphakameni okufanayo, isigxobo esithe mpo endaweni ephakeme kufanele sinwetshwe endaweni ephansi ngama-spans amabili futhi ahlelwe ngesigxobo.
(4) Izinyathelo zokudonsa amanzi kufanele zibhekwe nge-scaffolding foundation. Ukuphakanyiswa komhlaba ongezansi kwesizinda sokuphamba kufanele kube ngu-50mm kuphakeme kunesitezi semvelo yangaphandle, futhi uhlangothi lwangaphandle lwesipho se-pole kufanele lubekwe nomgodi wokudonsa ngengxenye engaphansi kwe-200mm.
