There are three prominent problems affecting the safety operation of buried PE gas pipes. First, the locations of pipes are unclear, which causes the third party damage. Second, pipes which are winded by the roots of plants have the risk of being damaged by the roots while typhoon coming. Last, the rosette plants can affect the emergency repair operation. The countermeasures have been put forward combined the characteristics of the city gas, which can benefit the safety operation of the city gas.
