Water-swellable rubber plate for impermeable wall

Abstract

The invention relates to a water-swellable rubber plate for an impermeable wall. According to the technical scheme, the water-swellable rubber plate is characterized in that an upper notch is formed in one side of the upper portion of a main plate, a lower notch is formed in the other side of the lower portion of the main plate, a pre-buried connecting piece is arranged in the portion, at the upper notch, of the main plate, moreover, the inner end of the pre-buried connecting piece is raised, and is connected and fixed to an upper sieve pore plate, the outer end of the pre-buried connecting piece extends out of the main plate, a preset connecting hole is formed in the portion, at the lower notch, of the main plate, and penetrates through a lower sieve pore plate, and the lower sieve pore plate and the upper sieve pore plate are connected through a plurality of sieve lines. The water-swellable rubber plate has the beneficial effects that the water-swellable rubber plate is manufacturedthrough a special water-swellable rubber plate vulcanization mold, moreover, an inner cavity, the pre-buried connecting piece, the sieve lines, the upper sieve pore plate and the lower sieve pore plate are combined together, the integral specially-made water-swellable rubber plate is formed through vulcanization, connection among the water-swellable rubber plates is achieved through the mechanicalforce of the pre-buried connecting pieces and the preset connecting holes, then the mutually-matched upper notches and lower notches are tightly combined, so that a leakage problem does not exist among the specially-made water-swellable rubber plates.

Description

technical field [0001] The invention relates to a waterproof device for a seepage-proof wall used in buildings or dams, in particular to a water-swellable rubber plate for the seepage-proof wall. Background technique [0002] The anti-seepage wall is a continuous wall built in a loose permeable layer or an earth-rock dam (weir) to prevent seepage. It is widely used in dams and buildings. Its bottom is embedded in bedrock or relatively impermeable strata to a certain depth, that is It can cut off or reduce the seepage water flow in the foundation, which is very important to ensure the seepage stability of the foundation and the safety of the dam. Due to its reliable structure, good anti-seepage effect, adaptability to various stratum conditions, and simple construction, the anti-seepage wall technology is especially effective in dealing with hidden dangers of seepage deformation such as dam foundation leakage, "flowing soil" behind the dam, and "piping" Good, has been widely...

AI Technical Summary

Problems solved by technology

The existing problems are: the high elastic modulus of the concrete cut-off wall causes the high stress of the wall, the strength and impermeability of the plastic concrete cut-off wall are low, and the durability is poor; the wall is generally thick, which makes the cost Improvement; the construction site is too large, the construction period is long, and the original dam is greatly disturbed; in addition, the concrete made of cement is an inorganic mineral material, and its own stability is very good

The existing problem is: because the water directly contacts the anti-seepage wall, although a soft organic anti-seepage film is designed, the effect is still not very satisfactory, resulting in shortened service life of the anti-seepage wall

The existing problems are: the anti-corrosion plastic board may still have hidden dangers of water leakage, and the joints of multiple anti-corrosion plastic boards will inevitably leak, which will still shorten the life of the concrete wall after a long time

[0007] In addition, the existing water-swellable rubber is generally made directly according to the required expansion coefficient according to the formula, and does not require too strong strength and connecting components, so it cannot be directly applied to the construction of anti-seepage walls, and cannot exert its excellent waterproof properties. performance
