The positioning protrusion is inserted into the positioning groove to facilitate the splicing and installation of the first concrete base plate and the second concrete base plate.
[0044] Working principle: By setting a first notch and a first slot on the first concrete base plate, and a second notch and a second slot on the second concrete base plate, when the first concrete base plate and the second concrete base plate are spliced together, the first plug-in plate and the second plug-in plate on the waterproof plate can be inserted into the first slot and the second slot. This allows the waterproof plate to cover the joint and simultaneously fix the first and second concrete base plates. The elastic sealing strip is sleeved on the first and second concrete base plates, which not only seals but also fixes the concrete base plates and provides deformation space, thereby improving the waterproof effect. The third and fourth slots, third and fourth plug-in plates can further achieve the purpose of waterproofing. The locking nuts and screws facilitate the fixing of the waterproof plate, making the first and second concrete base plates more firmly fixed.
