Abstract
Description
Technical Field
[0001] This application relates to the field of building engineering technology, and in particular to a drainage structure that facilitates keeping the concrete layer of a basement dry. Background Technology
[0002] A basement is a room whose floor level is more than half the room's net height below the outdoor ground level. Multi-story and high-rise buildings require deeper foundations; to utilize this height, a basement is built beneath the ground floor. This increases usable floor space and saves on backfilling, making it relatively economical. Constructing a basement below the ground floor improves land use efficiency.
[0003] Almost all basements in the residential complex suffer from varying degrees of leakage, severely impacting residents' use and generating numerous complaints. Repair measures often involve grouting, but leaks frequently reappear in other areas after one section is plugged, making it difficult to address the root cause. Furthermore, repeated grouting can cause the concrete structure to become porous, affecting its durability. Summary of the Invention
