It took 42 years to build a dam in India, but it collapsed on the first day of operation. Why does it take so long to build a dam?

It took 42 years for India to build a dam, which should be caused by insufficient material supply, serious technical support or financial interruption. It will never take 42 years to build a dam under normal circumstances.

The dam that India spent 42 years building collapsed on the first day of operation because of the mouse hole, which shows that the dam quality is unqualified. If the quality of the dam is qualified, it is impossible for rats to make holes in the qualified dam without problems with raw materials. It took 42 years to build a dam in India, and there must be a shortage of materials. If there were sufficient materials, it wouldn't take so long.

A serious lack of technical support will also slow down the progress of the project. Without strong technical support, it is very difficult to build a dam. Building a dam is different from building a residential building, which requires a large number of technicians to cooperate to complete the design and construction of the dam main body. Under special circumstances, if the technical means are not advanced enough to solve some problems in a short time, it will seriously slow down the progress of bus construction.

In addition to the above two reasons, the possibility of capital supply interruption is the greatest. The cost of building a dam is very huge. If a country does not have enough financial support to bear the cost of dam construction, it will lead to the interruption of dam construction. India's per capita income is around $ 800- 1000, and it has just emerged from poverty according to the standards of the United Nations. In the case of India's national economy, it took 42 years to complete it, probably because of insufficient capital supply.
