Nowadays, although the Chinese highway and bridge construction technology has been relatively perfect, but there are still some problems must be overcome. Only when all these difficulties can be properly solved can we effectively develop expressways and carry out construction on roads and bridges in China.

Water conservancy projects can play an effective role in the allocation of water resources to play a role in flood control and drought relief. It plays an important role in social construction and economic development. China has also invested a lot of resources in water conservancy construction, but during the construction of water conservancy projects, due to the poor operation and management mechanism of water conservancy projects, the project can not play its own engineering benefits. Combined with the importance of establishing the operation management system of water conservancy projects, this paper briefly expounds the disadvantages of current water conservancy project construction, and puts forward relevant solutions for reference.

In recent years, China vigorously develops the water conservancy engineering industry, promote the construction of water conservancy projects, the scale of water conservancy projects is also gradually expanding. In the construction process of water conservancy projects, if the relevant management personnel do not scientifically and reasonably manage and control the construction cost, then it will have a direct impact on the overall effect of water conservancy projects, and it will also hinder the development of water conservancy projects in China. In addition, in recent years, China often appears drought and flood disasters, in order to reduce the occurrence of disasters, to protect people’s life safety and property safety needs to promote the development of China’s water conservancy industry, so China’s government needs to increase the investment in water conservancy projects. Therefore, this paper makes an in-depth analysis and discussion of the budget control measures of the construction cost of water conservancy projects for readers’ reference.

In recent years, China’s rural economy has developed rapidly, and more advanced agricultural technology is constantly applied to agricultural production, including water-saving irrigation technology. Large distribution of water resources in China, different areas of water resources quantity also different, and water resources can have important influence on the development of agriculture and production, in the process of agricultural planting need to consume a lot of water resources, if the shortage of water supply, will directly affect the agricultural production. The application of this technology can not only effectively improve the production quality and production efficiency of agriculture, but also improve the utilization rate of water resources, thus effectively promoting the economic income of farmers. Therefore, this paper deeply analyzes and discusses the water-saving irrigation technology and application in irrigation and water conservancy projects for readers’ reference.

In the new era, with the rapid development of China’s water conservancy industry, the safety production construction of small and medium-sized water conservancy project construction site is also facing new challenges. Especially with the advent of the era of big data, the original construction site safety management mode and supervision mechanism can not be well applied, which can not reflect the “visualization” of construction site safety management and production management. In this regard, in order to promote the transformation of safety production management mode in the construction site of water conservancy projects, strategies such as scientific division of work areas and living areas, construction of on-site safety signs, and improvement of visual safety detection tools are put forward, so as to build a visual safety production management system in the construction site and promote the safe and stable development of China’s water conservancy engineering industry.
