7. A docking method based on the pipeline connecting device for municipal drainage engineering according to claim 6, which is characterized in that: the method comprises the following steps:
firstly, arranging a lower protective half shell (71) at an installation position, and fixing a butt joint pipe (11) by means of a butt joint pipe positioning and installation mechanism (8);
placing one end of two drain pipe bodies (21) close to the butt joint pipe (11) into two sides of the lower protection half shell (71), clamping the bottoms of the drain pipe bodies (21) into semicircular grooves (72) at two ends of the lower protection half shell (71), and enabling the pressing control mechanism (4) to be positioned at the inner side of the lower protection half shell (71);
thirdly, respectively aligning the two drain pipe bodies (21) with the joint pipes (12) at the two ends of the joint pipe (11) by means of the joint guide limiting mechanism (6), and sleeving the two drain pipe bodies (21) on the two joint pipes (12);
Step four, the pressing rod (33) is rotationally pressed towards the drain pipe body (21) by taking the movable shaft (32) as a center, at the moment, the inclined surface of the wedge-shaped pressing and fixing block (34) is pressed towards one side of the pressing and fixing ring (37) far away from the butt joint pipe (11), then the installation arc groove (46) corresponds to the arc protrusion (35), and then the installation outer ring (41) is pushed to slide towards the butt joint pipe (11) along the sliding guide rib (44) until the rectangular groove (36) corresponds to the inner side of the rotating control ring (43);
step five, an external spanner rod is inserted into the rotation auxiliary assembly to drive the rotation control ring (43) to rotate relative to the installation outer ring (41), the wedge-shaped surface of the wedge-shaped compression guide block (45) is matched with the rectangular groove (36) on the arc-shaped bulge (35), the compression rod (33) is pressed towards the drain pipe body (21), the inclined surface of the wedge-shaped compression fixing block (34) is pressed towards the compression fixing ring (37) and the drain pipe body (21) towards the butt joint pipe (11), the control ring check mechanism (5) ensures that the rotation control ring (43) cannot reversely rotate to loosen the drain pipe body (21) and the butt joint pipe (11);
and step six, the two pressing fixing rings (37) are tightened by using the drain pipe body tightening mechanism (9), so that the two drain pipe bodies (21) are tightly pressed to the butt joint pipe (11), and then the upper side protection half shell (71) is fixed at the top of the lower side protection half shell (71), so that the butt joint of the two drain pipe bodies (21) is completed.
