Description
Technical field
The utility model relates to dyke seepage control technical field, particularly relates to a kind of flexible high and uniform impervious wall of transmission coefficient.
Background technology
Earth and rockfill dam is most widely used in world's dam engineering construction and a kind of dam type with fastest developing speed.In China, the ratio of earth and rockfill dam has exceeded 90%, is have the maximum country of earth and rockfill dam in the world.
Impervious wall is that one builds the ground diaphragm wall playing antiseepage effect in loose pervious layer or earth and rockfill dam (weir).Impervious wall technology originates from Europe in the 1950's, because of advantages such as its structure are reliable, good seepage-proof property, all kinds of formation condition of adaptation, easy construction and cost are low, especially respond well on the seepage deformation potential problem such as " stream soil ", " piping " behind process leakage of dam foundation, dam, be at home and abroad widely used.China's water conservancy and hydropower covering layer and earth rock cofferdam etc. have the general first-selected impervious wall of the Anti-seeping technology of anti-consolidation pressure.
At present, using is concrete cut the most widely.And concrete cut mainly contains ordinary concrete impervious wall, steel concrete impervious wall, Clay-concrete impervious wall, plastic concrete cut-off wall and mortar impervious wall.Concrete cut is underwater concrete, often causes the phenomenon having folder mud in part concrete in the process of building.If with a large amount of gravel in folder mud, will have a great impact the anti-seepage effect of impervious wall.And concrete cut has certain rigidity, by the impact that bottom basement rock retrains and is out of shape, easily occur fracture, this is a hidden danger of dyke seepage control safety.In addition, the transmission coefficient of concrete cut is difficult to control, and has very large discreteness, or may cause potential hidden danger.
Therefore, prior art existing defects, needs to improve.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of flexibility high and the uniform impervious wall of transmission coefficient.
The technical solution of the utility model is as follows: the utility model provides a kind of flexibility high and the uniform impervious wall of transmission coefficient, comprise some flocking together and form the monomer of wall shape, described monomer is graininess, described monomer is met water and is expanded, described monomer comprises a kernel and by the integument of described kernel sealed envelope, described integument is made up of water proof material.
The particle diameter of described monomer is 1-10 centimetre.
In each monomer, the proportion of described kernel and described integument is greater than 1.
Described kernel is made up of heavy material.
Described kernel is made up of stone or gravel.
Described impervious wall is used for earth and rockfill dam.
Adopt such scheme, high and the uniform impervious wall of transmission coefficient of flexibility of the present utility model, be made up of some monomers forming wall shape that flocks together, construction technology is simple, relative to existing construction of concrete cut off wall technique, mud plant, agitator need not be constructed, significantly reduce construction cost; And grooving operation and construct impervious wall operation and can synchronously carry out, does not have the setting time of concrete construction, improves speed of application and efficiency; In work progress, fluting need not divide groove section, and there is not the problem that impervious wall connects, quality of wall is high, and after becoming wall, permeability parameters is balanced, flexible high, not by the impact of dam body deformation.

Fig. 1 is the structural representation that the flexible high and uniform impervious wall of transmission coefficient of the utility model is applied to earth and rockfill dam.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Fig. 3 is the structural representation of monomer in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refer to Fig. 1 to Fig. 3, the utility model provides a kind of flexibility high and the uniform impervious wall 2 of transmission coefficient, comprises some flocking together and forms the monomer 4 of wall shape.Described monomer 4 is in graininess, and it is met water and expands, and keeps enough dilations, and therefore, during construction, much such particle 4 flocks together, and just can form impervious wall, construction technology is simple.
Described monomer 4 is in graininess, and its particle size is determined according to dykes and dams type and scale, and in actual applications, the particle diameter of described monomer 4 is generally 1-10 centimetre.Described monomer 4 comprises a kernel 42 and by the integument 44 of described kernel 42 sealed envelope.In each monomer, described kernel 42 is greater than 1 with the proportion of described integument 44.Described kernel 42 is made up of heavy material.Described kernel 42 is preferably made up of stone or gravel, and raw material is cheap.Described integument 44 is made up of water proof material.In the present embodiment, described integument 44 comprises clay, cementing agent, combined material, diaphragm etc., and described cementing agent can promote the bonding of integument and kernel.Clay preferably selects swell soil, as calcium-base bentonite or sodium bentonite.The swell soil selected reaches the secondary swell soil index of petroleum department's ministry standard " drilling fluid swell soil " (SY5060-93) defined.Clay can also use attapulgite soil, organic clay etc.Cementing agent is a kind of macromolecular material, comprises cellulosic polymer, guar gum.Combined material comprises gypsum and the plaster of paris.Diaphragm is formed by acrylic resin.
Described impervious wall is preferred in earth and rockfill dam 6, concrete application process: along the center line of the impervious wall for being formed, low to dam from dam crest milling slot, the sediment of cleaning bottom land.Directly being toppled over by multiple graininess monomer piles up in groove, piles up to apart from 0.5-1 rice, groove top, adopts the backfilling of earthwork dug out to cover top afterwards.After graininess monomer 4 is combined with seepage water, hydrolysis can be there is and expand, thus formed one uniform, stick, non-penetrative and have fabulous flexible impervious wall 2.
Described impervious wall 2 can also be applied to Landscape River, the antiseepage of bank protection bottom, the antiseepage of refuse landfill bottom, purification tank for liquid waste and reservoir etc.
In sum, the utility model provides a kind of flexibility high and the uniform impervious wall of transmission coefficient, be made up of some monomers forming wall shape that flocks together, construction technology is simple, relative to existing construction of concrete cut off wall technique, mud plant, agitator need not be constructed, significantly reduce construction cost; And grooving operation and construct impervious wall operation and can synchronously carry out, does not have the setting time of concrete construction, improves speed of application and efficiency; In work progress, fluting need not divide groove section, and there is not the problem that impervious wall connects, quality of wall is high, and after becoming wall, permeability parameters is balanced, flexible high, not by the impact of dam body deformation.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
