In one embodiment of the diaphragm wall structure shown in fig. 1, the diaphragm wall structure includes a wall body and a plugging assembly, and the diaphragm wall structure can effectively prevent the inrush of pressure water through the embedded casing.

The wall body is arranged in a foundation pit, the thickness of the wall body of the current common diaphragm wall is 600mm-1200mm, and the specific thickness of the wall body needs to be determined by the size of the foundation pit, the position of the wall body, geological conditions and the like during construction. When the underground diaphragm wall is matched with the prestressed anchor cable support system for construction, a plurality of steel reinforcement cages which are sequentially distributed need to be arranged on the wall body, embedded sleeves are arranged in the steel reinforcement cages, and serve as an optimal implementation mode, the embedded sleeves are steel sleeves, and great convenience is brought to later-stage anchor cable construction through the embedded sleeves. And one end of the embedded sleeve far away from the center of the foundation pit is an open end.

The shutoff subassembly is located the open end, and be connected with the open end switching, the shutoff subassembly includes bottom plate 2, shutoff board 1 and fastener 3. The bottom plate 2 is arranged at the opening end of the embedded sleeve and is fixedly connected with the reinforcement cage, as an optimal implementation mode, the periphery of the bottom plate 2 is fixedly welded with the reinforcement cage, and the center of the bottom plate is a through hole with the same inner diameter as the embedded sleeve. The blocking plate 1 is detachably connected with the bottom plate 2 through a fastener 3, is suitable for blocking the open end of the embedded sleeve, and is in threaded connection as an optimal implementation mode; and a sealing structure is arranged between the plugging plate 1 and the bottom plate 2, and is a sealing rubber gasket 4 as an optimal implementation mode. The fasteners 3 are a plurality of bolts annularly arranged at the opening end of the embedded sleeve.

The size and the number of the plugging components in the embodiment are determined by the following steps: firstly, determining the processing sizes of an embedded sleeve, an embedded steel plate and an anchor bar according to engineering design parameters (such as the thickness of a diaphragm wall, the diameter of an anchor rope anchoring body, a vertical direction inclination angle and the like); and secondly, determining the processing parameters of the bottom plate 2, the plugging plate 1, the fastener 3 and the sealing rubber mat 4 in the structure according to the parameters of the embedded sleeve.
