Description

Technical Field

[0001] The utility model relates to the technical field of underground continuous walls, in particular to an anti-circulation joint for underground continuous walls. Background Art

[0002] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water interception, anti-seepage, load-bearing and water retaining structure.

[0003] During the construction, the underground continuous wall is connected one by one through multiple groove sections to form a closed water-stop curtain on the outer layer of the foundation pit. In the process of connecting the groove sections, joints are naturally formed one after another. At present, I-beam joints are mostly used in the construction of underground continuous walls. During the construction process, the joints are often not cleaned due to bypass flow in the preceding groove section. The subsequent poured concrete and the I-beam joints cannot be tightly combined, resulting in water seepage in the ground-connected wall at the steel joints, affecting the construction quality of the ground-connected wall, increasing the safety risks in the subsequent foundation pit excavation process, and seriously endangering the safety of the foundation pit excavation. In addition, the I-beam is relatively bulky and not easy to install. At the construction site, it is necessary to use large mechanical equipment for hoisting and positioning, which not only increases the construction difficulty, but also affects the construction progress. In order to solve the above problems, the utility model proposes an anti-bypass joint for the underground continuous wall. Utility Model Content
