The front end of the water glass injection pipe is a jacketed pipe structure. The jacket of the jacketed pipe structure is a dual-liquid mixing chamber. The dual-liquid mixing chamber is connected to the water glass injection pipe and a check diaphragm is provided between the two. The inner pipe wall of the jacketed pipe structure is provided with a plurality of through holes. The front end of the cement slurry injection pipe is a liquid outlet pipe provided with a plurality of through holes on the pipe wall.

[0029] Combined with attachment Figure 1-Figure 3A slurry mixing device of a double-liquid grouting machine includes a water glass injection pipe 1 and a cement slurry injection pipe 2. The front ends of the water glass injection pipe 1 and the cement slurry injection pipe 2 are connected with a mixing pipe 3. The mixing pipe 3 contains a double-liquid mixing chamber 4. The double-liquid mixing chamber 4 is equipped with a first spiral pipe 5 and a second spiral pipe 6. Specifically, the cement slurry enters the mixing pipe 3 at the front end from the cement slurry injection pipe 2, and the cement slurry enters the double-liquid mixing chamber 4 and the second spiral pipe 6 under pressure. Similarly, the liquid in the water glass injection pipe 1 enters the mixing pipe 3 at the front end, enters the double-liquid mixing chamber 4 and the first spiral pipe 5, and after being fully mixed in the double-liquid mixing chamber 4, is injected into the construction site through the discharge pipe 9.

[0030] Specifically, the cross-sectional diameter of the second spiral pipe 6 is larger than the cross-sectional diameter of the first spiral pipe 5 .

[0031] When the utility model is implemented, Figure 2 As shown. The first spiral pipe 5 is connected to the water glass injection pipe 1, and the cement slurry injection pipe 2 is connected to the second spiral pipe 6. The first spiral pipe 5 is located inside the second spiral pipe 6. A connecting pipe 7 is connected between the first spiral pipe 5 and the second spiral pipe 6. Specifically, the liquid in the first spiral pipe 5 or the second spiral pipe 6 is transferred to the opposite pipe through the connecting pipe 7, so that the mixing effect is better. The outlets of the first spiral pipe 5 and the second spiral pipe 6 are connected to a mixing box 8, and the mixing box 8 is located in the mixing pipe 3. A discharge pipe 9 is installed at the end of the mixing pipe 3 away from the water glass injection pipe 1, and a discharge hole 14 is provided on the mixing box 8. The first spiral pipe 5 and the second spiral pipe 6 complete the secondary mixing through the mixing box 8, enter the mixing pipe 3 through the discharge hole 14, complete the third mixing, and are then injected into the construction site through the discharge pipe 9.

[0032] When the utility model is implemented, Figure 2 As shown, a first separator 10 and a second separator 11 are installed in both the water glass injection pipe 1 and the cement slurry injection pipe 2. Separation ports 12 are provided in the first separator 10 and the second separator 11. Both the first separator 10 and the second separator 11 are funnel-shaped. The two ends of the first separator 10 are connected to the water glass injection pipe 1 and the first spiral pipe 5, respectively. The two ends of the second separator 11 are connected to the cement slurry injection pipe 2 and the second spiral pipe 6, respectively. The cement slurry enters the second separator 11 at the front end of the cement slurry injection pipe 2, enters the mixing pipe 3 through the separation port 12, and then enters the second spiral pipe 6 from the outlet, completing the separation of the cement slurry. Similarly, the water glass liquid also enters the mixing pipe 3 and the first spiral pipe 5 through the first separator 10. Under the pressure of the pump, the water glass injection pipe 1 and the cement slurry injection pipe 2 enter the mixing pipe 3 and mix. The liquids are then separated and mixed by the first spiral pipe 5 and the second spiral pipe 6, completing the mixing in the two-liquid mixing chamber 4.

[0033] A guide tube 13 is installed on the inner wall of the mixing tube 3, and the side wall of the guide tube 13 is an inwardly inclined structure.

[0034] A discharge hole 14 is provided on the mixing box 8 .

[0035] The inlets of the water glass injection pipe 1 and the cement slurry injection pipe 2 are both equipped with one-way valves, which can effectively prevent the mixed liquid from flowing back to the other pipeline during the pumping process of the water glass injection pipe 1 and the cement slurry injection pipe 2, prevent the occurrence of internal blockage in the mixing device, and prevent the occurrence of liquid diversion.

[0036] Embodiment one:

[0037] The cement slurry enters the mixing tube 3 at its front end from the cement slurry injection pipe 2, and the cement slurry enters the double-liquid mixing chamber 4 and the second spiral pipe 6 under the action of pressure. The liquid in the water glass injection pipe 1 enters the mixing tube 3 at its front end, and enters the double-liquid mixing chamber 4 and the first spiral pipe 5. The liquid in the first spiral pipe 5 or the second spiral pipe 6 is transferred to the opposite side pipe through the connecting pipe 7, so that the mixing effect is better. The first spiral pipe 5 and the second spiral pipe 6 complete the secondary mixing through the mixing box 8, and then enter the mixing tube 3 through the discharge hole 14 and the mixed liquid directly into the double-liquid mixing chamber 4 to complete the third mixing, and then is injected into the construction site through the discharge pipe 9.

[0038] Example 2:

[0039] The cement slurry enters the second separator 11 at the front end of the cement slurry injection pipe 2, enters the mixing pipe 3 from the separation port 12, and then enters the second spiral pipe 6 from the outlet to complete the separation of the cement slurry. Similarly, the water glass liquid also enters the mixing pipe 3 and the first spiral pipe 5 through the first separator 10. Under the pressure of the pump, the water glass injection pipe 1 and the cement slurry injection pipe 2 enter the mixing pipe 3 and mix the liquids, and then pass through the barrier classification mixing of the first spiral pipe 5 and the second spiral pipe 6 to complete the mixing in the double-liquid mixing chamber 4.

[0040] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
