Grass bags play an important role in flood prevention and flood prevention. Every year, the southern flood control department must order large quantities of high-quality straw bags from our factory as materials for flood control and flood prevention. The use of straw bags in flood prevention and flood prevention is to open the straw bag and put it into the soil. After the soil is installed, tie the edges and put it in a dangerous place layer by layer to prevent flooding. Flood control construction has a direct bearing on people's lives and property and must be treated with caution.
1 Flood control planning: It is a part of river basin planning and generally needs to be carried out independently and then combined with other specialized water conservancy plans. When flood planning is conducted, first of all, the natural conditions, socio-economic conditions, floods, and historical floods of the rivers or areas in question must be surveyed and investigated to obtain the necessary information, and a comparative plan should be drawn up, including the scale of the major flood control measures. Integrate comprehensive planning, compile plans for river flood control, urban flood control, and coastal flood control through comparison or optimization, and select the scale of the main flood control project and non-project flood control measures.
2 Engineering design: Select the project location (such as dam site, embankment line, flood diversion area, etc.) according to the selected engineering measures of the plan; then conduct survey, test and calculation according to project grade standards and requirements of protective objects, and propose the overall layout of the project. And the main building design of the various engineering characteristics, engineering quantities and investment estimates. Large-scale projects should also be prepared for construction planning or construction organization design.
3 Construction: Same as construction of general water conservancy projects. While the embankment construction and river excavation in flood control projects are generally large, they are relatively decentralized. In China and some countries, human resources are still used.
