Abstract

The invention relates to the field of vertical shaft gas pipe installation, in particular to a construction method for utilizing a raise-boring machine to mount a vertical shaft gas pipe. The construction method comprises the following steps: 1, excavating a vertical shaft; 2, mounting a gas pipe; and 3, pouring concrete to reinforce a pipe. With adoption of the construction method for utilizing the raise-boring machine to mount the vertical shaft gas pipe, the potential safety hazard caused by pipeline installation in an oblique lane and a drift is eliminated, fast efficient construction is realized, good reputation is gained, and high social benefit is created. The construction method for utilizing the raise-boring machine to mount the vertical shaft gas pipe is also suitable for installation of other mine types and other pipelines and can generate huge economic benefit.

Description

technical field [0001] The invention relates to the field of installation of vertical shaft gas pipes, in particular to a construction method for installing vertical shaft gas pipes by using a raise drilling machine. Background technique [0002] Some coal mines in Shanxi are high-gas mines, and the coal gas needs to be sucked and discharged to the ground through special gas pipes. The gas in part of the lower coal seam needs to pass through the lower roadway, the transport pedestrian slope between the upper and lower coal seams, and the upper roadway, and a very long large-diameter special gas pipe can be connected to the main gas pipe of the upper roadway. The traditional installation method not only requires a lot of gas pipeline materials, but also the large-diameter gas pipeline installed in the transport pedestrian slope affects ventilation and personnel walking, and also brings major unsafe hidden dangers to transportation safety. In view of this situation, it is pro...
