一、工程概况北京市郊区开挖三个养鱼池,取上填垫23亩低洼田地为良田工程。采用挖土机挖土装车,汽车运送,推土机推平的机械化施工方法。工程规模如图1。图1 取土坑与卸土场平面位置图经过测量计算,各取土坑的出土量α_i分别为:α_1=14000m~3;α_2=10000m~2;α_3=8000m~3;总土方量sum from 1 to 3α_i=32000m~3。各卸土场可容纳的土方量如表1。
First, the project profile Excavation of three fish ponds in the outskirts of Beijing, take the padding paddy 23 acres of low-lying fields for the farmland project. Excavator excavator using the loading and unloading, motor transport, push bulldozers mechanized construction methods. Project size shown in Figure 1. Fig.1 Plane location map of earth pit and unloading land After calculation, the excavated amount of each earth pit is α_1 = 14000m ~ 3, α_2 = 10000m ~ 2, α_3 = 8000m ~ 3, total earthwork sum from 1 to 3α_i = 32000 m ~ 3. The amount of earthwork that each unloading yard can hold is shown in Table 1.
