Buried gas engineering pipe

The utility model relates to the technical field of gas pipelines, in particular to a buried gas engineering pipe. Comprising two gas pipes, a connecting pipe is arranged between the two gas pipes, annular clamping grooves are formed in the two ends of the connecting pipe, one end of each gas pipe is slidably installed in the corresponding annular clamping groove, the gas pipes are fixedly sleeved with a plurality of annular clamps, a plurality of clamping holes are formed in the annular clamps in a penetrating mode, and the clamping holes are communicated with the annular clamps. The two ends of the connecting pipe are in contact with the corresponding annular hoops respectively, a plurality of buckle plates are arranged on the connecting pipe, the buckle plates are arranged on the corresponding annular hoops in a sleeving mode, a plurality of inserting rods are welded to the buckle plates, and the inserting rods penetrate through the corresponding clamping holes in a sliding mode. By means of the simple con
