[0002] With the continuous development of the construction industry, the application of underground space is becoming more and more extensive. Subsequently, the dense rigid waterproof sleeves for the external walls of basement structures have been increasingly favored by major construction enterprises. The application of dense rigid waterproof sleeves can protect the pipeline from external interference and ensure the smooth installation of the pipeline.

[0003] However, at present, due to the relatively dense rigid waterproof sleeves, the construction of traditional waterproof joint practices is difficult, there are high potential leakage hazards, and it may even affect the service functions of buildings. For this reason, the present invention proposes a dense rigid waterproof sleeve for the external wall of an underground structure and a construction method thereof to solve the above problems.
