In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The utility model provides a seal structure between metal sheet and prevention of seepage geomembrane, as shown in fig. 1 and fig. 2, mainly be applicable to the sealed of bottom of the pool support column bottom plate (metal sheet) and prevention of seepage geomembrane, including metal sheet 1, sealing washer, prevention of seepage geomembrane 3, sealing washer 4, apron 5 and fixing bolt 6.
The metal plate 1 is laid above the pool bottom, and the metal plate 1 belongs to weldable materials, so that the support columns can be fixedly welded above the metal plate, the support columns are prevented from being directly arranged at the pool bottom, direct welding and fixing cannot be achieved with the pool bottom, and the problem of poor sealing performance is solved.
The sealing ring is characterized in that a sealing groove 2 is prefabricated on the metal plate 1 and used for accommodating a sealing ring, the sealing groove can be set to be 1-4 circles or more according to actual engineering requirements, the specific size and the setting position are determined according to the sealing ring, and the sealing groove is preferably set in a concentric circle mode. The four corners (two corners at the top of the upper groove and two corners at the bottom of the groove) of the sealing groove are subjected to fillet treatment, the flatness of the inner surface of the sealing groove is about 0.05mm or less, and the sealing groove is free from phenomena of damage to the sealing ring, such as burrs, sharp corner blunting and the like. The bottom surface of the metal plate 1 is flush with the pool bottom, the upper surface of the metal plate 1 is a contact surface with the impermeable geomembrane 3, and the flatness of the upper surface is about 0.02mm or less; the sealing ring is placed in the sealing groove 2, the top of the sealing ring is slightly higher than the top of the sealing groove and generally about 2-3 mm in height, then the anti-seepage geomembrane 3 is laid above the metal plate 1 and the sealing ring, the anti-seepage geomembrane 3 needs to completely cover the sealing ring 4, and a certain margin (more than 200mm in width) needs to be reserved during lap joint so as to be in extrusion welding with the anti-seepage geomembrane 7; the anti-seepage geomembrane is a smooth anti-seepage geomembrane, and the surface is smooth and has no scratch. Then pressing the cover plate 5 on the anti-seepage geomembrane 3, wherein the edge of the cover plate 5 is required to exceed the outer edge of the sealing ring by more than about 30mm to completely cover the sealing ring 4; the stainless steel cover plate 5, the anti-seepage geomembrane 3, the sealing ring 4 and the metal plate 1 are pressed and fixed through the fixing bolt 6, the pressure generated by the fixing bolt 6 ensures that the sealing ring 4 is fully deformed and the sealing ring 4 is uniformly stressed, and meanwhile, the tail end of the fixing bolt 6 does not penetrate through the metal plate 1, namely, blind hole type connection is formed on the metal plate 1 so as to avoid the problem of no sealing caused by penetration; and then, reversely wrapping and sealing the fixing bolts 6 by using a reversely wrapped impermeable geomembrane 7, specifically, performing extrusion welding and sealing on the reversely wrapped impermeable geomembrane 7 and the impermeable geomembrane 3 reserved outside the cover plate 5, and performing reversely wrapping and sealing on the fixing bolts 6 one by one, but preferably, performing integral reversely wrapping and sealing on all the fixing bolts 6 of one circle at the same time.
