Abstract

PURPOSE:To liquefy generally used cement in the state without particles simply at practical field by making cement paste by using a mixer and by powdering the particles in the cement by a cement-crusher. CONSTITUTION:Hot water is suitably poured into the mixer 2 on a crusher 1 from a hot water-feeder, and then suitable amount of cement is fed thereinto and is agitated, thereby making cement paste. Further in order to accelerate to half-dissolution of coarse particles, a burner 5 is ignited, and after said material is boiled, it is dropped through a cock 4. While the paste in a tank mixer 9 of an arm 8 is agitated with the rotary action of a rotary shaft 6 and a worm gear 7, it is allotted and is dropped through the groove 11 of a dropping port 7, and simultaneously while the particles are removed under the condition without dewatering by the combined effect of a plurality of the rotary sliding action-crushers of the composite shape of the rubber blade 10 in a rotary rotor 13 and liners 12, 18, 19, the paste is dropped, and the residual fine particles collected in a semicircular mixer 14 correspondingly to the difference of specific gravity, is returned to the tank mixer 9 through a sand pump 21 and a return pipe 22.

Description

[Detailed Description of the Invention] The present invention relates to a method for easily liquefying general-purpose cement into a particle-free form on site, and it is used as a grout material, but the conventional stirring method, which is difficult to achieve, requires local water-stop target vein injection method. There are defects limited to. The cause of this is that due to the characteristics of cement, there are complex problems in simply making the particles insoluble.In particular, it is well known that the one-shot method has become too reckless and the desired penetration injection cannot be achieved even with fine powder cement. It is a fact. In order to eliminate the defects, we have improved the liquefaction method of our company's particle-free processing, which can be applied to all kinds of grouting methods. Since this is a much-needed liquefaction inhibitor injection pollution prevention geological improvement method, it is an epoch-making method for the improvement of sentient beings at a timely manner, and we would like to provide this invention and spread it widely. Yes. Therefore, the simple device shown in the diagram is as follows. ■ is a cement crusher ■ is a checker with a resistor on the side and the bottom ■ is a mixer at the top of the device in which the elastic rubber blades sliding against each other forcefully force the cement particles into semi-dissolution and abrasion ■ is a rubber blade ■ is a cock ■ is a kiln ■ is a rotating shaft ■ is a pair of worm gears
The stirring arm ■ is a middle tank mixer O is a three-layer spiral long-lasting rubber blade applied in one piece with 0. The tipper liner 0 is a rotating tipper rotor with [stock] and ■ on the outer periphery. The lower tank O is a quasi-semi-circular mixer. Rubber vane O is a connecting pipe and discharge port [Co., Ltd.] is a tipper liner with spiral grooves on the inner wall ■ is a tipper liner with checker-shaped unevenness on the inner wall is the chassis ■
Φ is sand pump Φ is retan pipe ■ is particle-free cement liquid. First of all, the C invention is ■Pour boiling water into the mixer on the crusher using a separate water heater, add an appropriate amount of cement, stir it to make cement paste, and then ignite the kiln to promote the dissolution of the coarse calves. From the boiling water, it drops through the cock.Due to the rotating action of the rotating shaft and the worm gear, the pesto in the tank mixer of the arm is stirred, and then the pesto drops through the Nissin at the same time as the rotor.
The combined effect of multiple crushers for rotating and sliding action with a composite shape of rubber vanes and ■■■ liners accelerates particle abrasion and achieves particle-free production without dehydration of the liver and kidneys. ＼Remaining fine particles are collected in a semi-circular mixer according to the difference in specific gravity and abraded again and again ＼Furthermore, they are returned to the tank mixer through the sand pump and the return pipe for repeated abrasion operations. This is a particulate-free cement liquefaction method in a 0-tank system, which is characterized by the constant continuous use of cement. ■The invention is almost the same as that, but ■It requires a little time without using a hearth, but it is easy and makes cement pesto by arbitrarily using either hot water or hot water.The following steps are also effective. is the same, so I'll leave it as an abbreviation and the main point is whether it's hot water or water.■ A particle-free cement liquefaction method that uses a mixer to make cement pest and uses a cement crusher to abrade the particles through repeated operations. There is.

Invention C is a general-purpose brittle material that does not increase the bearing capacity of the soil and uses an agent other than the base agent, that is, an acidic curing agent, in order to improve and toughen the instant condensation side heat construction method, which has the risk of causing temporary runoff and permanent pollution due to the addition of illegal chemicals. At this stage, we arbitrarily adopted auxiliary agents and retardants, etc., and mixed them with cement best in a mixer to make semi-thermal particles by skillfully utilizing the competitive dissolving power of acidic components. Since it is measured chemically, the following is a summary of operations and effects, so I will omit it and the main points are acid addition and ■Particle-free, which is characterized by a cement crusher that aims at particle abrasion through repeated operations. It is a cement liquefaction method.
