Description

Technical Field

[0002] The foundation pit is a pit dug at the design location of the foundation according to the base elevation and the plane size of the foundation. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the slope can be used to stabilize the slope, and the slope size is determined according to relevant construction regulations. For deep excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing; if there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation; in cold areas, natural cold air freezing method can be used for excavation, etc.

[0003] The existing deep foundation pit waterproofing is generally only done by construction workers laying a layer of waterproof membrane, which has low rigidity. During the construction process, the waterproof layer may be damaged due to external force, causing groundwater to continuously penetrate into the foundation pit, softening and deforming the soil, causing the foundation pit to become unstable and deformed, affecting the safety of the foundation pit and the progress and quality of construction.
