[0002] As we all know, earthwork is one of the main projects in water conservancy construction, including all aspects of earth (stone) excavation, filling, transportation, drainage, precipitation, etc. In civil engineering, earthwork includes: site leveling, roadbed excavation, civil air defense project excavation, ground filling, roadbed filling and foundation pit backfilling. The construction plan should be arranged reasonably and should not be arranged in the rainy season as much as possible. At the same time, in order to reduce the construction cost of earthwork, implement the principle of not occupying or occupying less farmland and arable land and facilitating land reclamation, a reasonable allocation plan for earthwork should be made and overall arrangements should be made.
[0003] The existing soil density test usually uses a ring knife, which is hammered into the soil, then dug out, and the soil inside the ring knife is taken out to bear the weight in order to find out the density of the soil. However, the existing ring knife is open at one end and sealed at the other end, and the error of the soil density measured by it is large. 1. If the ring knife is hammered into the soil too shallowly (such as Figure 5 1. If the ring cutter is driven too deep into the soil (as shown in Figure 6 As shown in the figure, the soil inside the ring cutter is blocked by the top of the ring cutter and squeezed again, and the calculated earth density is relatively large; during the operation, it is difficult for the staff to ensure that the top of the ring cutter is flush with the ground, which results in a large error in the earth detection.
