One: Use a horizontal viewpoint. Compared with developed countries, the level of use of cement pipes in China is relatively low, especially for the use of large-diameter pipes with a diameter of more than 2m, and the market has great potential for development. At present, the utilization rate of China's cement pipes and pipes in important water resources engineering fields such as water supply projects and farmland irrigation accounts for only 20%, which is still far from the 60% utilization rate in developed countries, especially in China's large population and regional In the case of uneven distribution and the backward level of overall water use
Second: the perspective of water resources. China's water resources are scarce, with regional and seasonal uneven distribution characteristics. Large-scale regional water transfers increase the demand for cement pipes ; China's total water resources are abundant, but per capita water resources are scarce; with the promotion of urbanization, the aging of network management The severe decline in water use rate has also brought a large impact on urban water use. The old city network management needs to be renewed urgently; the severe impact of long-term pollution, sudden pollution and salty tide has brought a serious crisis to China's urban water supply , Water quality (pollution) water shortage triggered the construction of a second water source. Drought and flood disasters are frequent, and the useful manipulation of disasters is now urgent, prompting the country's attention to engineering water shortage.
