As an important construction project connecting different regions, roads and bridges have an important impact on China’s economic development and cultural exchanges. As the saying goes: “To be rich, build roads first”. With a developed transportation system, it is possible to achieve better economic and cultural development in China’s vast territory. Therefore, the importance of municipal roads and bridges engineering is obvious, and the current quality requirements for roads and bridges are becoming stricter.
Over the years, with the development of urbanization, the quality of municipal road construction and water supply & drainage project has been greatly improved; while the urban transportation system has been continuously improved. Compared with the backward transportation system in the past, it has fundamentally improved and achieved leap-forward development. However, a series of municipal engineering problems were also reflected in those "crisp buildings" reported by various news sources a few years ago and various shoddy projects for now.
First of all, the construction quality supervision system is imperfect, and the management loopholes are large. Some government officials abuse their power, draw illegal interests from the construction of the project, and cut corners. The quality of construction is difficult to guarantee. Secondly, the level of construction technology is not high. Many technical problems cannot be fundamentally solved, but only traditional construction methods are used. Finally, due to the neglect of the maintenance work of the bridge, a series of quality problems such as collapse of the bridge and delamination of the pavement have occurred. There’s huge potential safety hazard.
Therefore, this book is divided into three parts to elaborate and analyze the municipal roads & bridges and water supply & drainage projects, hoping to promote the development of China’s municipal engineering construction.
