[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. Only by building a water conservancy project can we control the flow of water, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. During the trench excavation process, the excavator first excavates the trench, and then the construction workers go to the bottom of the trench to carry out construction work.
