Construction method for preventing leakage between underground enclosure structure and main body side wall

The invention discloses a construction method for preventing leakage between an underground enclosure structure and a main body side wall. The construction method comprises the following steps of, firstly, constructing an underground enclosure structure, and then cleaning the inner side surface of the underground enclosure structure; manufacturing a plurality of grouting pipes, forming slurry outlet holes in the periphery of each grouting pipe, then burning the grouting pipes in the inner side of the underground enclosure structure, and the upper ends of the grouting pipes protrude out of theunderground enclosure structure; and constructing a main body side wall on the inner side of the underground enclosure structure; connecting the upper ends of the grouting pipes to the grouting machine, and completing the grouting work. According to the construction method, a plurality of grouting pipes are pre-buried between the underground enclosure structure and the main body side wall, the grouting work is completed,
