Abstract: In the process of building basement construction, there are many problems, such as anti-buoyancy technical ability, equipment and facilities, lack of investigation and research in the early stage of the project, defects in architectural engineering design, lax quality control in the construction process, insufficient technical level of construction personnel,etc., which may cause instability of anti-buoyancy facilities of embedded drainage pipes in the basement of building engineering, and lead to pipeline penetration, fracture and other problems, thus causing damage to the basement of building engineering. In this paper, the construction technology of embedded drainage pipe in basement floor is studied based on construction cases.
