Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a foundation pit retaining wall structure. Background Art

[0002] It is generally believed that when excavating a foundation pit, it is necessary to keep the foundation pit dry and ensure the stability of the slope. Due to the existence of groundwater, some foundation pits are flooded or the soil is loose, some have "sand flow" causing slope collapse, and some internal foundation pit soil undergoes large displacement, affecting the safety of adjacent buildings. Therefore, due attention should be paid to the treatment of groundwater during foundation pit construction.

[0003] There are two methods for treating groundwater: water stopping and drainage. When excavating the foundation pit, a retaining wall is usually built inside the foundation pit to prevent groundwater from entering the foundation pit.
