Background technique

A water conservancy project is a project built for the purpose of controlling and deploying natural surface water and groundwater to achieve the purpose of eliminating harm and increasing profits. Also known as water engineering. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent flood disasters, and adjust and distribute water to meet the needs of people's lives and production for water resources.

The degree of compaction, also known as the degree of compaction, refers to the ratio of the dry density of soil or other road construction materials after compaction to the standard maximum dry density, expressed as a percentage. The most commonly used method for measuring the degree of compaction is the sand filling method. The sand filling method uses tools such as shovels or chisels for sampling. When digging a pit, the problem of large upper opening and small lower opening is likely to occur, which reduces the detection result. accuracy. At the same time, using the existing sampling tools, the digging time is longer, the moisture content of the sample will decrease, and the accuracy of the test results will also be reduced.
