[0036] Working principle: During construction, first, the pouring of the base 1 is completed to ensure its flatness and strength, providing conditions for subsequent water stop installation. The water stop belt 21 blocks a small amount of groundwater that tries to penetrate through the post-pouring belt due to its elastic deformation, forming the first waterproof barrier. Then, the solidification layer 22 prevents the water stop belt 21 from being damaged during subsequent construction and fills the small gap between the water stop belt 21 and the subsequent structure, enhancing the overall integrity. The closing net 24 prevents concrete from flowing into the post-pouring belt from both sides, ensuring structural integrity. The water stop plate 23 serves as the second waterproof barrier, working in conjunction with the water stop belt 21. When encountering groundwater seepage, it blocks the water flow from continuing to penetrate indoors. The reinforcing rib 5 improves the overall integrity and strength of the concrete structure in the post-pouring belt area, enhancing the structural rigidity. The limiting column 43 supports the horizontal plate 42, and the bottom side of the horizontal plate 42 is connected with the vertical plate 41, which blocks and limits the reinforcing rib 5 on the outside of one side of the vertical plate 41. The butt joint groove 44 on the outside of the water stop plate is connected with the top of the solidification layer, enhancing the connection strength and overall integrity. The water stop steel plate 6 uses its strength and rigidity to prevent groundwater from penetrating at the post-pouring belt. Through the cooperation of the bolt 35 and the connecting plate 31, it applies extrusion force to the concrete in the post-pouring belt area, making it more compact and reducing internal pores and gaps. The support plate 34 works together to constrain and densify the filling material, ensuring its compactness and waterproof performance. Multiple lines of defense work together to effectively prevent groundwater from penetrating from the post-pouring belt into the indoor, ensuring the waterproof effect and structural stability of the basement floor.
[0037] During the working process of the fixing mechanism 4, the limiting column 43 is closely attached to the reinforcing rib 5 to provide stable support capacity and ensure stability. The horizontal plate 42 and the vertical plate 41 cooperate with each other to form a stable support frame. The bottom of the vertical plate 41 is fixed on the top of the solidification layer 22, further enhancing the support capacity of 22. The butt joint groove 44 on the outside of the water stop plate 23 cooperates with the outside of the horizontal plate 42 to ensure that the horizontal plate 42 can be stably placed in the inside of the butt joint groove 44, achieving good connection. The design can well fix the water stop plate 23 and prevent it from being bent during pouring.
