The invention relates to a pipe gap type anchor rod supporting method. The pipe gap type anchor rod supporting method comprises the following steps of 1, drilling a hole, and drilling holes on the shoulder gap and the two sides in the circumferential direction of a top plate of a roadway to form drill eyelets; 2, making an anchor net closely attached to the top plate on the inner surface of the roadway; 3, installing an anchor rope supporting beam on the top plate of the roadway and binding the anchor net with an iron wire to be closely attached to and fixed to the anchor net, wherein the outer profile of the anchor rope supporting beam is the same as that of the top plate of the roadway, and the anchor rod supporting beam comprises two vertical bars and several cross bars; forming spacedholes in each pair of cross bar and the vertical bars at the two sides, wherein the spaced holes correspond to the drill eyelets one to one; 4, knocking the anchor rod, making the anchor rod penetratethrough a tray, spaced holes of an anchor rope supporting beam and the anchor net in sequence and then inserting the anchor rod into the drill eyelets; 5, knocking out the anchor rod into a pressurebearing rod, wherein the pressure bearing rod is in a T shape; 6, repeating the step 1-5 till the whole roadway is supported. Materials are convenient to obtain, transportation is convenient, the supporting strength is high, and the engineering cost is low.
