DIGGING GROUNDIn the process of construction of soil đầo, we proceed to execute sequentially for the construction of air-ground training and the construction of digging by manual. To đẳm construction safety manual. III. 2 MASS TRAINING GROUND:-As presented above, we proceed to dig 2 stages:-Construction of digging the ground by machine From natural essence (m 0.0) dig deep down to 5, m (-5 m) compared with natural ground Proceed to dig the whole project into a crater dug (Figure Drawing) -Digging by manual construction Manually edit about 10% of the land of abundance from Costa-2, 9 m to Costa 5, 1 m of hole diggingIII. 2.1 amount by air: -The amount of air is calculated on an area of within the peach pit. The distance from the outer edge to outer edge nail wall stations. To take advantage of the ability of construction machinery on the other hand to give the construction machines yet to the depth of the top of the pile we proceed to dig air to high peak's nail-5 m, the thickness of the soil need dig is: H = 5 m.
