In addition, the present invention sets a hydraulic pump 21, a grouting passage 22, a hydraulic passage 23, a gun head 26, a pressure gauge 24 and a flow meter 25 in the grouting control module.

The magnetic motor 111 and the inner magnetic rotor 112 are arranged on the high-pressure tank top 12, the magnetic motor 111 and the inner magnetic rotor 112 are connected, and one end of the stirring shaft 114 is fixed On the inner magnetic rotor 112, the other end of the stirring shaft 114 passes through the outer magnetic rotor 113 and the hydraulic drive disk 132 in sequence, and can slide relative to the outer magnetic rotor 113 and the hydraulic drive disk 132 in the axial direction of the stirring shaft 114. A groove is provided on the side wall of the stirring shaft 114, and a limiting protrusion is provided in the middle part of the outer magnetic rotor 113. The limiting protrusion matches the groove. The outer magnetic rotor 113 contacts the groove of the stirring shaft 114 through the limiting protrusion, so that the outer magnetic rotor 113 is driven to rotate through the stirring shaft 114.

[0073] Those skilled in the art will appreciate that in this embodiment, the magnetic motor 111 and the inner magnetic rotor 112 are disposed on the high-pressure tank top 12. As a configuration method, the magnetic motor 111 can be designed as follows: Figure 2 The shown socket form is directly connected to the upper end of the high-pressure tank top 12, and a buckle is provided inside the high-pressure tank top 12. The inner magnetic rotor 112 is set on the high-pressure tank top 12 by the buckle, so that the inner magnetic rotor 112 can rotate around the axis AA' without sliding along the axis AA'; the high-pressure tank top 12 is fixed to the top of the high-pressure tank body 131 by bolts, and the stirring shaft 114 is placed in the high-pressure tank body 131. One end of the stirring shaft 114 is fixedly connected to the inner magnetic rotor 112, and the other end passes through the outer magnetic rotor 113 and the hydraulic drive disk 132 in sequence.

[0074] In a possible embodiment, the grouting passage 22 includes: a first grouting sub-passageway 221, one end of the first grouting sub-passageway 221 is connected to the high-pressure tank top 12 of a corresponding high-pressure liquid storage tank 1; a second grouting sub-passageway 222, one end of the second grouting sub-passageway 222 is connected to the other end of the first grouting sub-passageway 221, and is connected to the high-pressure tank top 12 of a corresponding high-pressure liquid storage tank 1; a third grouting sub-passageway 223, one end of the third grouting sub-passageway 223 is connected to the other end of the second grouting sub-passageway 222, and is connected to the high-pressure tank top 12 of a corresponding high-pressure liquid storage tank 1; the other end of the third grouting sub-passageway 223 is connected to the gun head 26; wherein, the high-pressure liquid storage tanks 1 respectively connected to the first grouting sub-passageway 221, the second grouting sub-passageway 222 and the third grouting sub-passageway 223 are three adjacently distributed high-pressure liquid storage tanks 1, and the three high-pressure liquid storage tanks 1 are correspondingly placed on three corresponding bases 33.

[0075] Those skilled in the art will understand that Figure 1As shown, in this embodiment, a first grouting sub-passage 221, a second grouting sub-passage 222, and a third grouting sub-passage 223 are respectively set between the gun head 26 and the high-pressure liquid storage tanks 1 on the left, middle, and right, and are respectively connected to the corresponding high-pressure tank tops 12. The grouting of the high-pressure liquid storage tank 1 on the left is controlled by the first grouting sub-passage 221, the grouting of the high-pressure liquid storage tank 1 in the middle is controlled by the second grouting sub-passage 222, and the grouting of the high-pressure liquid storage tank 1 on the right is controlled by the third grouting sub-passage 223, so as to achieve the technical effect of grouting different slurries separately, so as to meet the actual needs of grouting multiple slurries in underground engineering to a greater extent. The present invention can set a corresponding number of grouting sub-passages according to the number of high-pressure liquid storage tanks, and the number of grouting sub-passages contained in the grouting passage 22 is not limited by this specification.

[0076] In one possible embodiment, a flow meter 25 is provided between the first grouting sub-passage 221 and the second grouting sub-passage 222; and / or, a flow meter 25 is provided between the second grouting sub-passage 222 and the third grouting sub-passage 223; and / or, a pressure gauge 24 and a flow meter 25 are provided between the third grouting sub-passage 223 and the gun head 26.

[0077] Specifically, the pressure gauge 24 and the flow meter 25 are provided so as to realize real-time control of the grouting parameters by observing the pressure gauge 24 and the flow meter 25 .

[0078] In one possible embodiment, a first liquid inlet valve 224 is provided on the connecting passage between the first grouting sub-passageway 221 and the high-pressure tank top 12 of a corresponding high-pressure liquid storage tank 1, for controlling the on-off of the first grouting sub-passageway 221; a second liquid inlet valve 225 is provided on the connecting passage between the second grouting sub-passageway 222 and the high-pressure tank top 12 of a corresponding high-pressure liquid storage tank 1, for controlling the on-off of the second grouting sub-passageway 222; a third liquid inlet valve 226 is provided on the connecting passage between the third grouting sub-passageway 223 and the high-pressure tank top 12 of a corresponding high-pressure liquid storage tank 1, for controlling the on-off of the third grouting sub-passageway 223; a fourth liquid inlet valve 227 is provided on the connecting passage between the other end of the third grouting sub-passageway 223 and the gun head 26, for controlling the on-off of the entire grouting passage 22.

[0079] Specifically, the first liquid inlet valve 224 can be provided to control the on-off of the first grouting sub-channel 221, the second liquid inlet valve 225 can be provided to control the on-off of the second grouting sub-channel 222, the third liquid inlet valve 226 can be provided to control the on-off of the third grouting sub-channel 223, and the fourth liquid inlet valve 227 can be provided to control the on-off of the entire grouting channel, thereby achieving the technical effect of separately controlling the grouting of different slurries. By providing the first liquid inlet valve 224, the second liquid inlet valve 225, the third liquid inlet valve 226, and the fourth liquid inlet valve 227, while achieving the control of the on-off of the grouting sub-channel and the entire grouting channel, it is also possible to achieve communication between several high-pressure liquid storage tanks 1. For example, the high-pressure liquid storage tank on the left can be connected to the high-pressure liquid storage tank in the middle by closing the fourth liquid inlet valve 227, the third liquid inlet valve 226, and the second liquid inlet valve 225 and opening the first liquid inlet valve 224.

[0080] In a possible implementation, a sealing ring is provided on the hydraulic drive disc 132 , and the sealing ring abuts against the side wall of the stirring shaft; the sealing ring is a highly elastic rubber sleeve.

[0081] Those skilled in the art will appreciate that there is a hole in the middle of the hydraulic drive disc 132 for the stirring shaft 114 to pass through, and a high-elasticity rubber sleeve is provided on the inner wall of the hole in the middle of the hydraulic drive disc 132. This is because when the stirring shaft 114 passes through the middle hole of the hydraulic drive disc 132, there may be a gap between the inner wall of the middle hole and the outer wall of the stirring shaft 114, which may cause the slurry above the hydraulic drive disc 132 and the liquid below to mix. Based on this, in the embodiment of the present invention, a rubber sleeve is provided on the inner wall of the middle hole of the hydraulic drive disc 132, so as to provide a gap between the inner wall of the middle hole and the outer wall of the stirring shaft 114. A sealing layer is formed between the side walls, and then the gap is filled by the sealing layer to prevent the slurry above the hydraulic drive disk 132 from mixing with the liquid below. Furthermore, since the stirring shaft 114 and the hydraulic drive disk 132 will rotate relative to each other, in order to avoid the change in the mutual extrusion force between the two during the rotation, which will cause different degrees of extrusion and uneven deformation of the rubber sleeve and affect the sealing effect, the embodiment of the present invention adopts a rubber sleeve with "high elasticity" performance to achieve the technical effect of further stabilizing the seal during the rotation of the stirring shaft 114 relative to the hydraulic drive disk 132.

[0082] In one possible embodiment, the hydraulic passage 23 includes: a first hydraulic sub-passage 231, one end of which is connected to the corresponding one of the high-pressure tanks 131 through a first hydraulic valve 234, and the other end is connected to the hydraulic pump 21; a second hydraulic sub-passage 232, one end of which is connected to the corresponding one of the high-pressure tanks 131 through a second hydraulic valve 235, and the other end is connected to the hydraulic pump 21; a third hydraulic sub-passage 233, one end of which is connected to the corresponding one of the high-pressure tanks 131 through a third hydraulic valve 236, and the other end is connected to the hydraulic pump 21; wherein the high-pressure tanks 131 respectively connected to the first hydraulic valve 234, the second hydraulic valve 235 and the third hydraulic valve 236 are three adjacently distributed high-pressure liquid storage tanks 1, and the three high-pressure tanks 131 are correspondingly placed on three corresponding bases 33.

[0083] Specifically, the hydraulic passage 23 includes a first hydraulic sub-passage 231, a second hydraulic sub-passage 232, and a third hydraulic sub-passage 233, which are respectively used to connect the hydraulic pump 21 and a corresponding high-pressure tank body 131, so as to facilitate the pumping of water into the corresponding high-pressure tank body 131 through the hydraulic pump 21, thereby pushing the hydraulic drive disc 132 in the high-pressure tank body 131 to move and squeeze the slurry; a first hydraulic valve 234, a second hydraulic valve 235, and a third hydraulic valve 236 are set between the first hydraulic sub-passage 231, the second hydraulic sub-passage 232, and the third hydraulic sub-passage 233 and the corresponding high-pressure tank body 131, so as to respectively control the opening and closing of the first hydraulic sub-passage 231, the second hydraulic sub-passage 232, and the third hydraulic sub-passage 233 through the first hydraulic valve 234, the second hydraulic valve 235, and the third hydraulic valve 236, so as to achieve the technical effect of respectively controlling the movement of the hydraulic drive disc 132 in one or more corresponding high-pressure tank bodies 131 and squeezing the slurry.

[0084] In a possible implementation, the high-pressure tank top 12 and the high-pressure tank body 131 are made of a tempered glass material with a see-through function.

[0085] Specifically, in order to withstand high hydraulic pressure, the high-pressure tank top 12 and the high-pressure tank body 131 can be customized with tempered glass. The purpose of providing a perspective function is to facilitate observation of the internal conditions of the high-pressure tank body 131, such as the rising speed of the hydraulic drive disc 132 under the action of the hydraulic pump and the extrusion of the internal slurry.

[0086] In order to enable the stirring shaft 114 to continuously rotate along with the inner magnetic rotor 112 , in a possible implementation manner, one end of the stirring shaft 114 is welded to the inner magnetic rotor 112 .

[0088] Specifically, since the bottom of the high-pressure tank body 131 of the high-pressure liquid storage tank 1 needs to be connected to the hydraulic passage, a single hole 3311 needs to be opened at the bottom of the tank body base on which the high-pressure liquid storage tank 1 is placed for the hydraulic passage to pass through.

[0089] This embodiment can realize multi-liquid sequential grouting and multi-liquid mixed grouting, and is described by taking double-liquid sequential grouting and double-liquid mixed grouting as examples. Slurry A and slurry B are respectively loaded into Figure 1 Of the high-pressure tank on the left and the high-pressure tank in the middle, the high-pressure tank on the right is empty.

[0090] When performing dual-liquid sequential grouting, first close the second liquid inlet valve 225 and the third liquid inlet valve 226, close the second hydraulic valve 235 and the third hydraulic valve 236, open the hydraulic pump 21 and the first hydraulic valve 234, observe the rising of the hydraulic drive disc 132 in the left high-pressure tank 131, and open the first liquid inlet valve 224 and the fourth liquid inlet valve 227 when the rising speed is stable, and control the grouting parameters in real time by observing the pressure gauge 24 and the flow meter on the first grouting sub-channel 221; after the grouting of slurry A is completed, close the first hydraulic valve 234 and the first liquid inlet valve 224, open the second hydraulic valve 235, observe the rising of the hydraulic drive disc 132 in the middle high-pressure tank 131, and open the second liquid inlet valve 225 when the rising speed is stable, and control the grouting parameters in real time by observing the pressure gauge 24 and the flow meter on the second grouting sub-channel 222, thereby realizing dual-liquid sequential grouting.

By observing the flow meter on the first grouting sub-channel 221, a certain volume of slurry A is injected into the high-pressure tank 131 on the right; then, close the first liquid inlet valve 224 and the first hydraulic valve 234, open the second hydraulic valve 235, observe the hydraulic drive disc 132 in the middle high-pressure tank 131 Observe the rising situation of the hydraulic drive disc 132 in the right high-pressure tank 131, and open the third liquid inlet valve 226 and the fourth liquid inlet valve 227 when the rising speed is stable. Observe the pressure gauge 24 and the flow meter on the third grouting sub-channel 223 to control the grouting parameters in real time, and realize double-liquid mixed grouting.

[0092] In the above embodiment, the high-pressure tank on the right can be empty or filled with other slurry, which can be set according to actual construction requirements.

[0093] It is worth noting that the magnetic stirring system of this embodiment is in continuous operation when the slurry is stored in the tank and pumped. In addition, if multi-liquid mixed grouting (three or more slurries) is required, it can be achieved by simply adding a high-pressure storage tank with a magnetic stirring system and corresponding piping.

[0094] This embodiment can be applied to a variety of underground engineering conditions, and a variety of slurry materials and grouting pressures are selected to achieve continuous stirring of the slurry during the grouting process. At the same time, it realizes real-time and precise adjustment of the slurry ratio according to on-site requirements, which is of great significance to the development of grouting technology in actual engineering.
