TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a underground continuous wall anti-seepage structure. BACKGROUND

[0002] The underground continuous wall is a continuous underground wall body with the functions of anti-seepage, soil retaining and load bearing, which is formed by using some special trenching machines on the ground, with the help of the wall protection of mud, to dig a narrow and deep foundation trench underground, and pouring appropriate materials in the foundation trench. At present, the construction of the basement of urban high-rise buildings and subway stations requires excavation of foundation pits. The foundation pit is deep, and the environmental protection requirements around the foundation pit are high. In order to control the adverse effects on the surrounding environment during the excavation of the foundation pit, the underground continuous wall is often used as a vertical soil retaining and water retaining structure around the foundation pit.

[0003] The underground continuous wall anti-seepage structure is disclosed in the existing patent file with the publication number CN211006726U. The existing technology proposes that due to the characteristics of the construction process of the underground continuous wall, the construction along the foundation pit edge is divided into slot sections. The underground continuous wall is composed of several wall sections, and the adjacent wall sections are poured in stages. Therefore, the joints between the wall sections of the underground continuous wall are prone to water seepage. The joint seepage prevention of the wall sections is a key problem. Especially when the underground continuous wall is used as a permanent outer wall of the underground structure, the joint needs better water stopping measures.

[0004] The above-mentioned scheme and the existing technology require corresponding anti-seepage treatment between the wall sections poured in stages. In the above-mentioned scheme, on the one hand, the tight connection effect between the wall sections is general. On the other hand, it is inconvenient to use between the wall sections of different thicknesses, and the construction flexibility is poor. It cannot meet the actual construction requirements and needs to be further improved and optimized.
