Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit structures, in particular to an anti-seepage type building foundation pit structure. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be decided based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done well. On rainy days, continuous rainfall will accumulate rainwater in the foundation pit. Since precipitation will continue for a period of time, the accumulation of water in the foundation pit for a long time will cause water seepage inside the foundation pit, which requires subsequent repairs and affects the normal construction progress.

[0003] In order to solve the above problems, a water-proof building foundation pit structure is disclosed in the Chinese utility model patent application disclosure specification CN219973211U.
