a. sticking the double-sided CPS-CL reactive adhesive waterproof coiled material (2) to the protruding part of the pipe gallery tongue-and-groove, then embedding pipe joint tenons (10) of two pipe joints and pipe joint tongue-and-groove (9) to form joints, stretching the two ends of the double-sided CPS-CL reactive adhesive waterproof coiled material (2), and respectively turning the two ends along the wall surface of the pipe gallery tongue-and-groove to be stuck to the inner side and the outer side of the pipe gallery; the seam and the double-sided adhesive CPS-CL react and adhere to the waterproof coiled material (2) to form an inner gap isolated from the end part of the seam and an outer gap communicated with the end part of the seam;
b. pouring an oil-soluble polyurethane consolidation body (4) into the internal gap of the joint through the grouting pipe hole (5), and filling a bi-component sealant (3) into the external gap through the end part of the joint;
c. the single-sided CPS-CL reactive adhesive waterproof coiled material (1) is stuck on the outer side (7) of the pipe gallery, and the seam end and the turnover end of the double-sided CPS-CL reactive adhesive waterproof coiled material (2) are completely covered, and the self-adhesive waterproof adhesive tape (6) is stuck on the inner side (8) of the pipe gallery, and the seam end and the turnover end of the double-sided CPS-CL reactive adhesive waterproof coiled material (2) are completely covered.
8. The method for waterproofing a tongue-and-groove joint of a prefabricated assembled utility tunnel according to claim 7, wherein: the bi-component sealant (3) is a bi-component polyurethane sealant.
9. The method for waterproofing a tongue-and-groove joint of a prefabricated assembled utility tunnel according to claim 7, wherein: the oil-soluble polyurethane consolidated body (4) is elastic gel made of polyurethane chemical grouting material.
