Designation of typical team of construction machinery at execution of earthwork

摘要

Diploma deals with procedure for designation of optimal group of construction machinery for execution of earthwork. Through comparisons, which based upon relationship of capacity of construction machines and capacity of transport vehicles and also price of realizations of earthwork, we decide which type of excavation and transport mechanizations, is from cost and time point of view, considering extend and geologic composition, most suitable. In continuation I determined concept theoretical capacity - Kteo, that we reduce for value of correction factor – F and we get practical capacity - Kpra, on which based in diploma showed comparisons. In combinations of excavation machines, I was choosing machines with analogous practical capacities and because it is only these for every machine, that performance in combination different, we consider capacity of machine at combination, that has lower capacity. Excavation combinations of machines are made from one or more types. For every type of machine or combination of machines, we have different types of individual machine per choice, that distinguish considering relationship capacity/price. In continuation I was comparing cost for m³ excavation material in different geologic compositions, and productivity of execution of excavation, that are achieved by excavator without cooperation of other machines, combination of wheel loader and dozer, and combination of excavator and dozer. In last part I showed procedure of choice of optimal excavation group of machines on concrete instance.
