Concrete impermeable wall

Abstract

The invention relates to a concrete impermeable wall. According to the technical scheme, the concrete impermeable wall comprises a concrete wall body, water swelling rubber plates and a top protectionrubber sleeve; a water insulation layer composed of the multiple water swelling rubber plates is arranged outside the concrete wall body, the top protection rubber sleeve is arranged on the top of the concrete wall body, the lower portion of the section of the concrete wall body is of a trapezoid structure, the upper portion of the section of the concrete wall body is of a cuboid structure, and the water swelling rubber plates are of structures gradually thinned from the bottom to the top. The concrete impermeable wall has the beneficial effects that reinforced concrete is used as a foundation, the water swelling rubber plates are used for seepage and moisture prevention, the top protection rubber sleeve is used for top protection of the concrete wall body, and the aim of protecting the reinforced concrete is achieved; a reinforcing steel bar bundling frame structure of the reinforced concrete are in rigid connection with water swelling rubber plate embedded connecting parts, protection and foundation connection are integrated, construction is simplified, and the service life of a concrete dam is greatly prolonged.

Description

technical field [0001] The invention relates to a construction-friendly anti-seepage wall and a method thereof, in particular to a concrete anti-seepage 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 used at home and abroad. my country...

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
