Description

TECHNICAL FIELD [0001] The present invention relates to a grouting material mixing apparatus and a grouting material mixing method using an electromagnetic force,

The present invention relates to a grout mixing apparatus and a grout mixing method using an electromagnetic force. More particularly, the present invention relates to a grout mixing apparatus and a grout mixing method using an electromagnetic force, To a grouting mixer and a grout mixing method using an electromagnetic force capable of enhancing the quality of grout by providing a high quality grout by accelerating hydration reaction.

Generally, a mixture of cement and water is called a 'grout' and is also called 'cement paste'. Grout is used for construction or civil engineering, and it is widely used especially when it is injected into soft ground to reinforce soft ground, to receive groundwater flowing in the ground, or to fill a crack.

A conventional conventional grout mixing apparatus includes a mixing tank having a discharge port for discharging cement mixed with cement and water and a discharge port for discharging cement mixed with the cement and water, a motor driven by a motor supported on an upper portion of the mixing tank, A mixing blade installed at a lower portion of the driving shaft and rotated according to the rotation of the driving shaft; and a charging unit installed at an upper portion of the mixing tank so as to be able to open and close and to be charged with cement and water.

In this way, a conventional grout mixing apparatus opens grout, mixes cement and water at an appropriate ratio, puts it into a mixing tank, and rotates the mixing blades to make grout.

However, in the conventional grout mixing apparatus, when cement and water are put into a mixing tank, a part of the cement forms a water layer of one layer and forms a cement paste which is not mixed with water sufficiently. The cement paste having a large particle size is broken by the mixing blades Small particle size pastes are not broken by mixing blades, and eventually the cement particles forming the water film will not react sufficiently with water. Accordingly, cement particles which are not sufficiently reacted with water are injected by grouting or become a concrete structure. Such a concrete structure has problems in that strength and durability are inferior, or voids are formed in the grout structure, resulting in deterioration of the life and economy of the structure.

The mixing vessel 100 is not particularly limited as long as the grout material and the grout material using water as a base material can be introduced and discharged. The composition of the charging unit 110 and the discharging port 120 may be various forms or systems As shown in FIG.

An opening / closing device (not shown) is formed in the discharge port 120 so that the material in the mixing container 100 is closed so that the material in the mixing container 100 is not discharged while mixing the grout material.

Here, the mixing vessel 100 is preferably made of a nonconductive insulating material such as a resin stream.

In the above description, the grout material is exemplified by cement and water, but in addition, one or more functional materials may additionally be added and mixed at an appropriate ratio.

The stirring unit 200 includes a driving shaft 210 rotatably supported at an upper end of the mixing vessel 100 and extending into the mixing vessel 100 and a driving motor 210 driving the driving shaft 210 And a stirring vane 230 formed at a lower end of the driving shaft 210 and rotating according to the rotation of the driving shaft 210 to stir the grout material.

Next, the electromagnetic force generating unit includes an inductor (coil) 310 wound around the mixing vessel 100 with a predetermined winding, and a power supply unit (not shown) for supplying a current of a predetermined intensity to the inductor 310 Hour).

The winding of the inductor 310 is determined so that the size of the electromagnetic field required for the concrete is determined according to the physical properties of the concrete.

For example, the inductor 310 may be configured such that two or more unit inductors can be connected to and disconnected from each other. Thus, the inductor 310 can be wound around the inductor 310 according to the physical properties of the unit, Connected or disconnected so as to determine the size of the electromagnetic field required for this.

Operation and effect of the grout material mixing apparatus using the electromagnetic force configured as described above will be described.

When the motor 220 of the stirring unit 200 rotates by the control of the motor control unit of the control panel 400, the stirring blade of the driving shaft 210 rotates, So that the cement and water are stirred and stirred.

When a predetermined electric pulse wave is applied to the inductor 310 under the control of the pulse generating unit of the control panel 400 while current is supplied by the current supplying unit together with the stirring operation of the stirring unit 200, The electromagnetic field is generated.

The electromagnetic field generated by the inductor 310 relaxes the surface tension of the grout and smoothly adsorbs between the cement particles and the water molecules, thereby increasing the stirring efficiency and improving the fluidity of the grout material.

In other words, the molecule of water has a dipole structure, and when the electric pulse wave is applied, the flow characteristic can be changed by controlling the motion of the water molecule. That is, by applying an electric force to the grout material to relax the surface tension, the cement particles are sufficiently mixed with the water molecules to accelerate the hydration reaction, so that a good quality grout can be produced.

The inventors of the present invention have confirmed by experiment that the surface tension of the material. 4 is a graph showing the surface tension over time for distilled water performed by the inventor of the present invention.

The inventor of the present invention applied electromagnetic force to the second distilled water over time in the experiment. As shown in Table 1 below, the surface tension of the distilled water exposed to the electromagnetic field for 60 minutes or more was remarkably decreased. As can be seen from this, the application time of the electromagnetic field is preferably 60 minutes or more, and it is confirmed that when applied to the grout mixer container, the cement particles and water can be sufficiently mixed through the relaxation of the surface tension.
