This segmented assembly method is more convenient during installation, reduces the difficulty of construction, and improves the overall stability, making the grouting pipe more sturdy and reliable. It not only effectively improves the construction efficiency of the grouting pipe and reduces the complexity of construction, but also effectively prevents water seepage from occurring in the base plate and improves the waterproof performance of the base plate. The present application sets the grouting pipe inside the water collection well (original layout or newly added), which can better guide groundwater flow, avoid water retention under the base plate, and further reduce the occurrence of water seepage problems in the base plate.

[0022] Preferably, the second grouting pipe 3 is 200 mm higher than the top surface of the basement floor 1, and the end of the second grouting pipe 3 away from the first grouting pipe 2 is also covered with a conduit cover 30. By setting the conduit cover, top sealing measures are taken, and by adopting a special segmented assembly and waterproof design, the connection between the floor and the grouting pipe is made firmer.
