4.Xu technical reasons when earthworks:
Before conducting the embankment to collect instruments, equipment, clean up trash and pump out the water grass and then poured the soil. Soil was transported to the dump with cars, new land pour uneven shape and can not be filled at locations close to the edge walls, columns should be arranged 3 workers 2 mission is leveled and compacted soil Date fixed ground. The thickness of each layer dress and period dress on a square meter is determined by the pilot dress at the scene to determine the criteria appropriate for the type compactor:
+ Editing layered dress accordingly with the machine.
+ determine the number of dress according to the actual conditions.
+ determine optimum moisture when compacted.
in the case of loose soil when watering must always dress.
Choose compactor: MTR - 80HR produced in Japan, with the specifications:
+ Size dress: 850x375x ((31400-26800) + (37000-30400) mm
+ the dress size: 375x300 mm
+ amplitude shock: 55 mm
+ Power dam: 1200 kg
+ Weight: 81 kg.
III.2.4. Design moving line during the construction land:
1. Design of online moving excavator:
-According on selecting reverse bucket excavators EO-3322B1 codes, so the machine moving backward toward follows. At each location excavators dug down to a given aggregate, truck
waiting beside land, filled every time
the excavator bucket turned to pour always up trucks. the cycle work of excavators and two machines shipping is calculated according to the above is the match to avoid wasting time waiting several machines.
• String movement designed excavators dug side by side strips; all bands
