[0002] In the process of underground retaining structure operation, underground continuous wall structure has become one of the important retaining structures. In order to facilitate the construction of the project, it is usually carried out in sections. In order to strengthen the water stopping and connection effect between the sections, H-shaped steel or cross-shaped steel plates and other steel are usually embedded between the sections. However, in order to reduce material waste and facilitate the construction of subsequent operations, the embedded steel between the sections is only buried to the top of the underground continuous wall. Therefore, when pouring the concrete of the underground continuous wall, the over-poured part of the concrete on the top of the wall can easily bypass the top of the embedded steel on the top of the wall and flow into the adjacent sections. When the adjacent sections can be excavated, the inflowing concrete has been consolidated and formed on the top of the wall.
