The specific reason has not been announced by the police for the time being, but it can be guessed according to the situation on the spot, and some reasons can be summarized according to the previous collapse accident. A kind of collapse accident is because the foundation pit of the foundation is dug deep in the construction site or project, which leads to insufficient foundation support and deformation of the slope, which leads to the burst and collapse of the underground water pipe.

The above reasons are that a series of dangers caused by improper construction can actually be effectively avoided, but there is also a kind of ground collapse, that is, underground pipeline rupture, which will also lead to ground collapse. Pipeline rupture is difficult to be noticed by people and is a potential safety hazard. Then, the soil structure of the land is loose, the road is in a state of long-term maintenance, coupled with long-term rain erosion,

However, the long-term disrepair of urban roads is still relatively rare, so according to other people's guesses, the reason of road collapse is probably because the underground water pipe broke after the rainstorm, and the spilled water led to loose soil, which led to ground collapse.

But the specific reasons still need to wait for the official investigation to give the exact news. Before it was made public, we just guessed, but it was reported that there were no casualties when the accident happened, which should be the best news. Now the subway station at Lvcuo intersection in Xiamen has also been closed, and the traffic nearby has been controlled. I hope the road can be repaired as soon as possible.
