oa Civil Engineer in South Africa - Efficient use on construction of tractor mounted rippers

 

Abstract

The factors which affect the selection of a method to loosen in situ material in earthworks operations are presented with particular reference to the corresponding contract pricing structure. The characteristics of rippability classification systems and the requisite exploratory investigations are briefly reviewed. Controlled excavation is discussed in detail in respect of the specification and performance of the machine, the principles of modern tractor mounted rippers and the concepts of economic and mechanical ripping. Layouts, procedures and examples of ripping trials are given. Recommendations with regard to the standardization of specifications for excavation classification are presented in conclusion.

Die effektiewe aanwending van trekkeraangedrewe skeurploeë word in die referaat bespreek. Die faktore wat die keuse van 'n metode van losmaak van die materiaal beïnvloed, word ondersoek met besondere verwysing na gepaardgaande kontrakprysstrukture. Die eienskappe van skeurbaarheidsklassifikasiesisteme en die vereiste eksplorasie-ondersoeke word kortliks behandel. Beheerde uitgrawing word in detail bespreek ten opsigte van die spesifikasie en werkverrigting van die masjien, die beginsels van moderne trekkeraangedrewe skeurploeë asook die beginsels van ekonomiese en meganiese braking. Uitlegte, prosedures en voorbeelde van skeurproewe word gegee. Tenslotte word aanbevelings met betrekking tot die standaardisasie van spesifikasies vir uitgrawingsklassifisering gemaak.
