Second, it is difficult to quickly fix the grouting pipe to the grouting hole, and disassembling the pipe after grouting is not convenient, reducing work efficiency. Therefore, we need to propose a new radial grouting device. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides: a radial grouting device, including a radial grouting rod 1, an installation cylinder 2 at one end of the radial grouting rod 1, an inner grouting tube 3 detachably installed on the inner wall of the installation cylinder 2, an outer grouting tube 5 connected to the installation cylinder 2 sleeved on the outer side of the inner grouting tube 3, and a sealing component for preventing grouting from splitting and overflowing on the inner wall of the radial grouting rod 1; grouting through holes 7 inclined to the direction of the grouting hole distributed on the surface of the outer grouting tube 5; a diversion pipe 18 connected to the other end of the radial grouting rod 1 via a connecting hose 16, the diversion pipe 18 connected to a grouting pipe 20 with a ball valve switch 21 installed via a pipe quick connector 19; an overflow baffle 22, the overflow baffle 22 is installed on the support frame outside the grouting hole, the radial grouting rod 1 passes through the overflow baffle 22 via a connecting guide cylinder 23, and the end of the radial grouting rod 1 is inserted into the grouting hole.

[0025] It is worth noting that the coordinated arrangement of the radial grouting rod 1, the inner grouting pipe 3, the outer grouting pipe 5, the anti-overflow baffle 22, and the closed component structure can effectively prevent a large amount of grout from overflowing when the grouting disassembly equipment is completed, reducing the waste of raw materials. At the same time, it can easily assemble the grouting pipe into the grouting hole and quickly fix and disassemble it, improving the efficiency of the grouting work.

[0026] The sealing assembly includes: a mounting bracket 9 installed on the inner wall of the radial grouting rod 1, and a limiting link 11 movably mounted on the surface of the mounting bracket 9; wherein, one end of the limiting link 11 is connected to a spherical plug 10 for grouting sealing, and the other end of the limiting link 11 is connected to a limiting disc 12. A return spring 13 is fitted on the surface of the limiting link 11, and one end of the return spring 13 is connected to the surface of the mounting bracket 9.

[0027] Specifically, the radial grouting rod 1 is a structure for installing the inner grouting pipe 3 and the outer grouting pipe 5, which facilitates grouting reinforcement inside the grouting hole. The mounting bracket 9 is a structure for assembling the spherical plug 10, which cooperates with the limiting link 11 to guide and limit the spherical plug 10. The limiting plate 12 is a structure that cooperates with the limiting link 11 to limit the spherical plug 10 and prevent it from becoming loose. The return spring 13 ensures that the spherical plug 10 seals the grouting channel inside the radial grouting rod 1, thereby achieving the effect of preventing overflow.

[0028] One end of the grouting inner pipe 3 is connected to an installation part 4, the surface of which fits into the inner wall of the installation cylinder 2. One end of the grouting outer pipe 5 has a connecting part 6 that fits into the surface of the installation cylinder 2, and a grouting port 8 is installed at the end of the grouting outer pipe 5.

[0029] The installation part 4 is the structure that connects the grouting inner pipe 3 to the installation cylinder 2, and the connection part 6 is the structure that connects the grouting outer pipe 5 to the installation cylinder 2. Through the cooperation of the installation cylinder 2 with the installation part 4 and the connection part 6, it is convenient to disassemble and replace the grouting inner pipe 3 and the grouting outer pipe 5 in the future, and it is convenient to use and carry.

[0030] An assembly portion 14 is provided at the other end of the radial grouting rod 1, and the inner wall of the assembly portion 14 is fitted to one end of the connecting hose 16. A locking cap 17 is movably disposed on the outer side of the assembly portion 14 on the surface of the radial grouting rod 1. The connecting guide cylinder 23 is disposed at the center of the surface of the overflow baffle 22, and the outer surface of the radial grouting rod 1 is connected to the assembly baffle 15. The radial grouting rod 1 passes through the assembly baffle 15 and is inserted into the interior of the connecting guide cylinder 23. The inner wall of the locking cap 17 is threaded to the surface of the connecting guide cylinder 23.

[0031] In addition, the assembly part 14 is a structure that connects the radial grouting rod 1 to the connecting hose 16. The diversion pipe 18 is used to divert the grout into multiple grouting pipes. With the grout diversion effect of the diversion pipe 18, multiple grouting holes can be grouted and reinforced at the same time, improving the grouting efficiency. The locking cap 17 is a structure that quickly fixes the radial grouting rod 1 to the anti-overflow baffle 22. The connecting guide cylinder 23 plays a guiding and limiting role in the installation of the radial grouting rod 1, improving the efficiency of the installation and disassembly of the radial grouting rod 1. The assembly baffle 15 is a fixing structure that cooperates with the locking cap 17.

[0032] Furthermore, the other end of the connecting hose 16 is connected to a branch end of the diversion pipe 18, and the other end of the grouting pipe 20 is connected to a grout tank via a pumping device. The surface of the overflow baffle 22 is provided with locking rods 24 that connect to the support frame, and the surface of the connecting guide cylinder 23 is provided with sealing plugs 25 for sealing. The sealing plugs 25 seal the connecting guide cylinder 23 after the radial grouting rod 1 is withdrawn, preventing internal grout from overflowing. The locking rods 24 are structures for installing and fixing the overflow baffle 22.

[0033] The spherical plug 10, limiting rod 11, limiting disc 12, return spring 13, and anti-overflow baffle 22 of the sealing component automatically seal the gap between the grouting rod and the hole during the grouting process, effectively preventing the grout from overflowing backwards. The elastic pressure of the return spring 13 ensures that the spherical plug 10 is in real time in contact with the grouting channel of the grouting rod, which reduces grout waste and avoids pollution of the construction environment.

[0034] The inner grouting pipe 3 and the mounting cylinder 2 adopt a detachable structure. The outer grouting pipe 5 is quickly connected through the connecting part 6, and with the threaded fastening design of the locking cap 17, the grouting rod can be quickly assembled. At the same time, the detachable structure facilitates the replacement of worn grouting pipe components, greatly improving maintenance efficiency. The grouting through holes 7 with their inclined surfaces, combined with the multi-branch grouting supply of the diversion pipe 18, allow the grout to penetrate the formation radially, which is especially suitable for reinforcing loose rock and soil, effectively expanding the grouting diffusion radius and reducing blind spots.

[0035] Simultaneously, it reduces the outward thrust generated by grouting pressure. Combined with the rigid locking structure of the baffle 15 and connecting guide cylinder 23, it can further withstand the reverse thrust of high-pressure grouting, preventing the grouting rod from coming out and ensuring construction stability. The overflow baffle 22, through the locking rod 24, is adaptable to various support frames, allowing the device to be flexibly applied to different support scenarios such as tunnels and slopes, reducing on-site modification costs. The sealing plug is a structure that seals the connecting guide cylinder 23 after the grouting rod is pulled out, reducing the possibility of grout overflow.

[0036] Furthermore, with the locking cap 17 and connecting guide tube 23, the radial grouting rod 1 can be easily assembled into the grouting hole, and can be quickly fixed and disassembled, improving the efficiency of grouting work.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
