An excavator, also known as an excavator, is developed on the basis of a mechanical transmission excavator. It uses a bucket to excavate materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to the stockyard. Periodic earth-moving machinery. If the small excavator is counted as one shift of eight hours a day, it can dig about 1500-2400 square meters a day, and the speed of digging is also linked to the operation method.
For the fuel consumption and excavation volume per hour of the excavator, take the commonly used crawler excavator (1m3) as an example, check the "National Unified Construction Machinery Shift Cost 2017", the diesel consumption is 63kg/shift, that is, 7.875kg per hour.
The excavation soil types of civil works and earthworks are classified according to the hardness of the soil. The standard for dividing dry soil and wet soil is based on the groundwater level. The soil above the groundwater level is dry soil, and the soil below the groundwater level is wet soil. The soils used in construction earthworks are classified as follows: Class I, II, III, and IV. Among them, the first type of soil refers to sand, humus soil, and the like. The second type of soil refers to loess, soft saline soil and alkaline soil, loose and soft gravel, sand mixed with gravel and humus. The third type of soil refers to clay or ice clay, heavy loam, coarse gravel, dry loess or loess with natural water content mixed with gravel, etc. The firmness coefficient of the soil is 0.81--1.0, and it must be excavated with a sharp shovel and a pick.
How many cubic meters of solid soil can an excavator dig in an hour
According to different models, the excavation volume is different. Model 35 has a 3.5-ton bucket capacity of 0.11; Model 60 has a 6-ton bucket capacity of 0.3 cubic meters.
Excavator model and bucket capacity regulations, model 35 is 3.5 ton bucket capacity is 0.11 cubic; model 60 is 6 ton bucket capacity is 0.3 cubic; model 120 is 12 ton bucket capacity is 0.5 cubic; model 160 The 16-ton bucket has a capacity of 0.65 cubic meters; the model 200 has a 20-ton bucket capacity of 0.8 cubic meters.
Model 220 has a 22-ton bucket capacity of 1.1 cubic meters; model 240 has a 24-ton bucket capacity of 1.2 cubic meters; model 270 has a 27-ton bucket capacity of 1.5 cubic meters; model 300 has a 30-ton bucket capacity of 1.6 cubic; model 400 has a bucket capacity of 40 tons at 1.9 cubic meters; model 250 has a bucket capacity of 45 tons at 2.1 cubic meters.
Because the 150 excavator is a 15-ton medium-sized excavator, the bucket capacity of the general preparation is 0.32 to 0.7 cubic meters. When digging, it can perform about 200 excavation operations per hour, and each time it can dig 0.5 cubic meters. About 100 cubic meters of soil can be excavated per hour. Therefore, one shift (8 hours) of 150 excavators can excavate about 800 cubic meters of soil.
