Description

technical field [0001] The application relates to the field of bridge demolition technology, in particular to a green demolition and reconstruction construction method of an existing bridge and a sewage collection device thereof. Background technique [0002] At present, with the rapid development of China's economy, in the field of infrastructure construction, especially the development and construction of roads and bridges, it provides a very strong guarantee and promotion for the vigorous development of the country's overall economy. In recent years, with the rapid growth of local economies, the original old and old roads and bridges can hardly continue to perform their role in providing strong support for economic development in terms of quality and function. Therefore, old and old bridges need to be demolished and rebuilt. [0003] The main composition of the bridge is based on reinforced concrete. The poured concrete structure must be demolished. There are many demolit...
