Abstract
The utility model relates to a mixing stirrer for two-fluid grouting to orifices. The mixing stirrer comprises a stirrer upper cover, a stirrer outer sleeve and a rotating device. The mixing stirrer is characterized in that the rotating device comprises a two-fluid-grout flow distributing piece, a connecting shaft, a pressing cover, a bearing, a driving fan blade, a driven fan blade, through holes and rotating-device fixing bolt holes. The mixing stirrer has the advantages that the two-fluid grout is injected into the mixing stirrer by a connecting pipe, the kinetic energy generated by flowing of the two grout fluids drives the driving fan blade and the driven fan blade to rotate so as to realize the purpose of mixing and uniformly stirring the two grout fluids; therefore, the energy-saving and environment protecting effects are achieved, simultaneously the uniform stirring of the grout fluids is realized, the two-fluid-grouting reliability is greatly improved, and the purpose that the two-fluid grout can be trustingly and scientifically grouted according to the design matching ratio determined by the test is realized.
Description
Technical field
Two kinds of mixing agitators that slurries inject when the utility model relates to a kind of vertical drilling aperture two fluid grouting, reinforced soft soil ground, the batholith that can be widely used in mine construction, municipal works rupture in the engineerings such as crushed zone reinforcing, reach water shutoff, improve stratum texts.
Background technology
Take pit shaft drilling engineering as example, when adopting freezing process to carry out shaft construction, need to carry out upright opening drilling construction.When running into soil property scall or being rich in creviced formation when drilling construction, and need to adopt the mode of two fluid grouting when causing occurring spillage situation, fill formation void and can reach the effect of rapid condensation.Two fluid grouting is a kind of method of solidifying rapidly of the slurries of bi-material (conventional cement mortar and waterglass in engineering) being mixed according to a certain percentage to rear injection stratum.And in the process of slip casting, can bi-material mix the direct quality that affects two fluid grouting uniformly.Evenly mixing can cause biliquid slurry to occur that clotting phenomenon, the rapid condensation of part slurry, concrement can not inject more greatly stratum and even occur plugging phenomenon; And the cement mortar mixing with waterglass part does not reach the effect that biliquid is starched after being as good as injection stratum with single liquid slurry; And because experiment cannot be simulated actual grouting operation condition, the match ratio being determined by experiment does not just have practical significance yet, the setting time of whole slurry will be uncontrollable.
Traditional two-liquid grouting device is a kind of three-port structure, can only play the effect of mixing, cannot guarantee that two kinds of slurries evenly mix, so that there will be the problems referred to above; And, during slip casting, two kinds of slurries are because flow is different, pressure is different, two kinds of slurries carrier pipe (for example cement grout enters waterglass slurries carrier pipe) that wherein a kind of slurries easily enter another kind of slurries under differential pressure action causes this slurries normally to carry even and to condense in carrier pipe in three-way pipe, causes plugging.
There is at present a kind of novel double liquid grout injecting mixer to solve above-mentioned pressure limit problem, in the situation that the pressure differential of two kinds of slurries is larger, also can normally make two kinds of slurries mix, but same not solution makes two kinds of mixed uniformly objects of slurries, better to reach slip casting effect, control slurries setting times.
Summary of the invention
Therefore, can not mixed uniformly problem in order to solve two kinds of slurries, the utility model spy improve double liquid grout injecting mixer, and biliquid slurry can evenly be mixed when slip casting, improves slip casting effect.
The utility model solves the technical scheme that its technical problem adopts: a kind of aperture two fluid grouting mixing agitator, comprises agitator upper cover, agitator overcoat and tumbler.Agitator upper cover and agitator overcoat are threaded connection.Tumbler is bolted on agitator and puts outward.Agitator upper cover comprises tube connector A, tube connector B and agitator upper cover handle, tube connector A, tube connector B are arranged on agitator and cover, biliquid slurry feed pipe is fed in mixing agitator and is realized the mixing of biliquid slurry, the object of uniform stirring by tube connector A, tube connector B respectively, the tube connector A of biliquid slurry, the setting of the pipe mouth angle of tube connector B in agitator are to be advisable perpendicular to active flabellum middle fan blade face, and the kinetic energy that can make full use of like this fluid drives the rotation of flabellum.On agitator, tops is provided with agitator upper cover handle.
The utility model also has following additional technical feature: through the biliquid slurries body after stirring, realize the closing up and shrink then to slip casting in sleeve pipe of injection slurry stream via necking down device again, slow down slurry and be attached to phenomenon on tube wall.
The beneficial effects of the utility model are: the stirring of biliquid slurry by two flabellums realizes and uniformly mixing, and are beneficial to after at the bottom of hand-hole and inject stratum; And the biliquid slurry of determining satisfactory match ratio through overtesting, even mixed initial set final setting time approaches experimental result, has accomplished that setting time is controlled, easily inject stratum, inject the controlled object of stratum range of scatter; The contraction that in addition, can realize biliquid slurry due to the effect of necking down device is avoided being attached on tube wall.
