穿越道路的防洪方涵改造设计

Reconstruction Design of the Square Culvert for Crossing Road Flood Control

现代城市道路建设发展迅速,为了提升城市道路的流量,使车速提高,在与现有的道路的连接时,就多有下穿的情况出现,这样原有道路上的配套的排水管线就受到影响,需要合理科学的对排水系统进行改造,使排水系统畅通,尤其是大的防洪排水方涵。

The Road construction in modem cities has developed rapidly. In order to upgrade the urban road traffic, so that the vehicle speed is increased, the situation of crossing road underground would more appear when the new road is linked with the existing road. So the drain line set of the existing road will be affected, and need to be modified reasonably and scientifically so as to enable smooth flow of drainage systems, especially the big flood control and drainage square culvert.
