Background
The prefabricated underground continuous wall has the advantages of shortening the construction period, improving the construction quality, improving the construction efficiency, shortening the influence on urban ground traffic and the like. With the continuous acceleration of the urbanization process in China, the prefabricated underground diaphragm wall is more and more widely applied to civil engineering, the joints of the prefabricated underground diaphragm wall are the weakest parts of the structure, and the mechanical property of the joints greatly restricts the bearing capacity, the waterproof property, the anti-seismic property and even the overall stability of the prefabricated underground diaphragm wall structure. However, the connection form and performance of the prefabricated underground continuous wall joint are rarely researched, and the application of the prefabricated underground continuous wall in engineering is severely limited. In order to ensure the overall performance and the impermeability of the prefabricated underground continuous wall, the selection of the proper joint form is one of the key problems to be considered in the construction of the prefabricated underground continuous wall. The integral stability of the existing prefabricated underground diaphragm wall joint is difficult to guarantee, the interval inside the joint is difficult to be compact, and the anti-permeability performance of the joint is difficult to guarantee. In addition, the structural style and the size of the prefabricated underground continuous wall board are produced and molded in a factory, the requirement on the on-site installation precision is high, the joint structure between adjacent underground continuous wall boards needs to meet certain integral occlusion, the joint structure form of the prefabricated wall board needs to be convenient to construct as much as possible, and the installation precision and the occlusion degree are easy to meet.
The prior art has the defects of insufficient capability of transmitting bending moment, shearing force and axial force; meanwhile, the waterproof effect is poor; the assembly is inconvenient.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
As shown in figures 1 to 5, a prefabricated assembled underground continuous wall king-shaped joint structure, including being symmetrical distribution's left side width of cloth underground continuous wall 1 and right side width of cloth underground continuous wall 7, still include that the butt joint department of left side width of cloth underground continuous wall 1 and right side width of cloth underground continuous wall 7 all is provided with the king-shaped joint 4 that improves the bonding performance between joint department king-shaped steel and the concrete, left side width of cloth underground continuous wall 1 and right side width of cloth underground continuous wall 7 on be provided with the reinforcing bar 2 that is used for improving intensity.
Two ends of the left side underground continuous wall 1 and the right side underground continuous wall 7 comprise reserved bolt holes 3.
Compared with the conventional Wang-shaped joint 4, the shear force and the bending moment are transmitted mainly by means of the natural adhesive force of the Wang-shaped steel web and the concrete, the concrete and the steel have large difference, the adhesive force between the concrete and the steel is relatively weak, the transmission effect of the shear force and the bending moment at the joint is poor, the integrity and the impermeability of the underground diaphragm wall can be influenced, the Wang-shaped joint 4 is connected by the bolt 6, the adhesive property between the Wang-shaped steel and the concrete at the joint is improved, the deformation resistance of the joint is improved, and the impermeability of the underground diaphragm wall is further enhanced.
