Description
Technical field
The present invention relates to material of construction, more specifically, relate to a kind of impervious blocking material and preparation method thereof.
Background technology
House, tunnel, dykes and dams and underground pipeline etc. all there will be the situation broken or damage, thus dykes and dams or underground pipeline etc. there will be the situation of leaking, seeping water, for tackling above-mentioned situation, the place of breakage is blocked by usual employing anti-seeping grouting material, causes breaking-up to avoid leaking for a long time or seep water to dykes and dams or underground pipeline.
Anti-seeping grouting material can be divided into cement grouting material (the granular injection material based on cement) and chemical grouting material two kinds according to the state of slurries, wherein, cement grouting material has that consolidating strength is high, price is low, transport and storage is convenient and grouting process is simple etc. advantage, but also also exist simultaneously time of coagulation long, easily by shortcoming that current dilute, therefore, be usually restricted when cement grouting material is used for leak stopping; The time of coagulation of chemical grouting material can regulate according to the needs of duration, chemical grouting material as polyurethanes can produce gel with water direct reaction, thus the impervious leakage-stopping of flowing water is gone for, but chemical grouting material is expensive, construction process requirement is high, is unfavorable for large-scale leak stopping.
At present, in general impervious leakage-stopping engineering, biliquid is usually adopted to control grouting technique, i.e. the grouting technique of cementation process and the combined chemistry of cement matrix material of chemical grouting.The setting time that biliquid controls the cement-chemical composite grouting material that grouting technique adopts is longer than the setting time of cement grouting material, and the tensile strength of cement-chemical composite grouting material is also enhanced simultaneously.But, when run into flow and be large and flow velocity high water burst time, the tensile strength of cement-chemical composite grouting material does not often reach construction requirement, and the slurries of sand-cement slurry are easily washed away, have a strong impact on water plugging effect.Therefore, can only take to accelerate slurries injection speed in the construction of reality and leak stopping is carried out in the measure strengthening slurries injection rates, but this can cause the huge wasting of resources, and then make the cost up of leak stopping.
Summary of the invention
The object of this invention is to provide a kind of impervious blocking material and preparation method thereof, with solve large to flow described in background technology and the water burst that flow velocity is high carries out leak stopping time slurries easily washed away problems.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of impervious blocking material, the raw material of described impervious blocking material comprises leaf fibres, gypsum, swelling agent, cement and water.

Preferably, described swelling agent is alumite plumping agent, sulphoaluminate expander, calcium oxide swelling agent or iron filings swelling agent.
A preparation method for impervious blocking material, the preparation method of described impervious blocking material comprises the following steps:
S01: select inclusion-free, without the leaf fibres rotted, and cutting carried out to leaf fibres, select gypsum, swelling agent and cement in described impervious blocking material raw material simultaneously;
S02: leaf fibres, gypsum, swelling agent and the cement after selecting is put into dispersion machine and stirs 3-5min, obtain the siccative mixed;
S03: joined by water in the siccative mixed, continues to stir 3-10min, obtains described impervious blocking material.
Preferably, described step S01 comprises: select the cement that weight percent is respectively the leaf fibres of 0.1%-0.25%, the gypsum of 3%-8%, the swelling agent of 3.5%-6% and 30%-55%.
Preferably, described leaf fibres comprises sisal fibers or abaca fibre, and described sisal fibers or described abaca fibre are cut into the staple fibre of 10-15mm.
Preferably, described leaf fibres comprises rice-straw fibre, and the preparation method of described rice-straw fibre is: staple fibre straw being cut into 10-25mm, and staple fibre is put in the NaOH solution immersion 30min that concentration is 1%, wash away clean with water again and dry, obtaining rice-straw fibre.
Preferably, described leaf fibres comprises rice-straw fibre, and the preparation method of described rice-straw fibre is: use pulverizer that straw is broken into thread staple fibre, and staple fibre is put in the NaOH solution immersion 30min that concentration is 1%, wash away clean with water again and dry, obtaining rice-straw fibre.
Impervious blocking material provided by the invention comprises leaf fibres, gypsum, swelling agent, cement and water.Can harden in atmosphere or in water after cement and gypsum add water, and cemented together securely for the materials such as sand, stone.Swelling agent in this impervious blocking material adds after in cement, and when cement setting hardens, swelling agent can expand and volume becomes large, swelling agent while expanding can compensate for shrinkage and the prestress of tension reinforcing steel bar, the gap fully between filling concrete.Leaf fibres has the advantages that intensity is high, water tolerance is strong, tenacity is strong, especially the intensity under water wets situation is higher, therefore, leaf fibres adds in sand-cement slurry to increase pulls power between leaf fibres and sand-cement slurry and leaf fibres, thus the tensile strength of this impervious blocking material is strengthened, and then the large and reactive force of the water burst that flow velocity is high of flow can be resisted, avoid the slurries of sand-cement slurry to be diluted by current.Meanwhile, the output zone of leaf fibres is wide, cheap, thus can reduce the raw materials cost of impervious blocking material.
