[0019] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0020] Example 1:

[0021] like Figure 1-4As shown in the figure, an embodiment of the present invention provides a grouting sealing device, including a base 1, a pipe 2, and an expansion pipe 3. A grouting connecting pipe 4 is connected to the base 1. The pipe 2 has an inner channel 21 and an outer channel 22. The grouting connecting pipe 4 is connected to the outer channel 22 and the inner channel 21 through a first connecting channel 11 and a second connecting channel 12, respectively. The outer channel 22 is connected to the expansion pipe 3. A one-way flow element 13 is provided in the first connecting channel 11. A switch element 14 is provided in the second connecting channel 12 to achieve the opening and closing of the second connecting channel 12. An anchor cable channel 15 is provided in the base 1. The anchor cable channel 15 is connected to the inner channel 21. A sealing component 5 is provided at the outer end of the anchor cable channel 15. The sealing component 5 is used for the passage and sealing of the anchor cable.

[0022] Specifically, the tube body 2 includes an inner hollow tube 23 and an outer tube 24. The upper end of the outer tube 24 is a sealed end. The inner hollow tube 23 has an inner channel 21. The outer tube 24 and the inner hollow tube 23 form an outer channel 22. The lower ends of the inner hollow tube 23 and the outer tube 24 are externally threaded. The lower end of the inner hollow tube 23 is longer than the lower end of the outer tube 24. The upper end of the anchor cable channel 15 of the base body 1 is provided with a stepped hole with internal threads that mates with the external threads of the inner hollow tube 23 and the outer tube 24.

[0023] For better sealing, a sealing gasket 25 is provided between the lower end of the outer sleeve 24 and the stepped hole.

[0024] Specifically, the expansion tube 3 is a rubber expansion tube, which is sleeved on the outer sleeve 24. The rubber expansion tube sleeve can be fixed by a common clamp in the art or by heat fusion. The outer sleeve 24 is provided with a connection hole 26 to realize communication with the expansion tube.

[0025] Specifically, the sealing assembly 5 includes a threaded body 51 and an anchor cable sealing spherical gasket 52 disposed inside the threaded body 51, which is connected to the lower end of the anchor cable channel 15 through the threaded body 51.

[0026] In some instances, the one-way flow element 13 is a one-way valve assembly, and the on / off element 14 is an on / off valve, which enables the on / off of the second connection channel 12.

[0027] In some instances, the switching element 14 is a pressure-breaking sheet, meaning that the pressure-breaking sheet is broken when the set pressure is exceeded, thus connecting the second connection channel 12. The pressure-breaking sheet is an aluminum sheet, and the aluminum sheet is fixed inside the second connection channel 12.

[0028] The working principle or operation method of this utility model is as follows: Grouting connection pipe 4 is connected to grouting equipment to start grouting. A pressure gauge can be set in grouting connection pipe 4. At this time, the switch 14 in the second connection channel 12 is in a closed state. The grout enters the outer channel 22 from the first connection channel 11 and finally enters the expansion pipe 3 through the connection hole 26. The expansion of the expansion pipe 3 seals the hole. The one-way flow member 13 plays the role of one-way flow and pressure maintenance. When a certain pressure is reached, the switch 14 is opened, and the grout enters the inner channel 21 from the second connection channel 12. Finally, the hole is grouted through the inner channel 21, and the anchor rod is cast into the hole.

[0029] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
