Therefore, the detailed description thereof will not be repeated.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-Figure 5 It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation on the present invention.

[0027] A deep and shallow hole grouting equipment, such as Figure 1As shown, it includes a shallow grouting pipe 1 and a deep grouting pipe 2, a grouting hole 3 is opened on the shallow grouting pipe 1 and the deep grouting pipe 2, a high-pressure rubber hose 5 is arranged on the shallow grouting pipe 1, a transition connecting pipe 4 is arranged between the shallow grouting pipe 1 and the deep grouting pipe 2, and the shallow grouting pipe 1 and the deep grouting pipe 2 are connected by the transition connecting pipe 4. Specifically, as shown in FIG. Figure 2 As shown, both ends of the transition connecting pipe 4 are respectively provided with a connecting platform 1 6 connected to the shallow grouting pipe 1 and a connecting platform 2 7 connected to the deep grouting pipe 2; the shallow grouting pipe 1 is provided with an internal thread at one end close to the deep grouting pipe 2, the connecting platform 1 6 is provided with an external thread and the connecting platform 6 is threadedly connected to the shallow grouting pipe 1; the deep grouting pipe 2 is provided with an internal thread at one end close to the shallow grouting pipe 1, the connecting platform 2 7 is provided with an external thread and the connecting platform 2 7 is threadedly connected to the deep grouting pipe 2.

[0028] The use of the transition connection pipe 4 can enhance the connection performance between the shallow grouting pipe 1 and the deep grouting pipe 2, and facilitates disassembly, replacement or maintenance. In some cases, the transition connection pipe 4 can be directly replaced or disassembled, which can simplify the operation steps, reduce the operation cost and improve the versatility. Figure 2 As shown, a high-pressure bursting valve 8 is provided at one end of the connecting platform 2 7 away from the connecting platform 1 6. The high-pressure bursting valve 8 is arranged on the transition connecting pipe 4, which is convenient for the use and maintenance of the high-pressure bursting valve 8, and can further reduce the cost while ensuring the performance.

[0029] like Figure 1-Figure 4 As shown, the connection between the transition connecting pipe 4 and the shallow grouting pipe 1 and the deep grouting pipe 2 is provided with a sealing fixing platform and a sealing body 9 located inside the sealing fixing platform. The sealing fixing platform on the transition connecting pipe 4 located on the side of the shallow grouting pipe 1 is a sealing fixing platform 12, and the sealing fixing platform located on the side of the deep grouting pipe 2 is a sealing fixing platform 2 13. The sealing fixing platform 1 12 is provided with a sealing groove 1 with an opening 19 facing the shallow grouting pipe 1, and the sealing fixing platform 2 13 is provided with a sealing groove 2 with an opening 19 facing the deep grouting pipe 2, and sealing bodies 9 are provided inside both the sealing groove 1 and the sealing groove 2.

The retarder 11 extends into the transition connecting pipe 4 and can be connected with the grouting deep pipe 2. The transition connecting pipe 4 is a spiral pipe. The retarder 11 is used to prevent pipe blockage during deep hole grouting. The transition connecting pipe 4 with a spiral pipe structure can fully mix the retarder and the grouting liquid, so that the final setting time and strength of the grouting liquid are guaranteed to a certain extent.

[0033] like Figure 1 , Figure 5 As shown, a support assembly is provided below the grouting head 24 located outside the grouting hole of the shallow grouting pipe 1, and a grouting pipe 10 is provided in the grouting port 25 at the grouting head 24. The support assembly includes a support platform 20, and the grouting head 24 in the shallow grouting pipe 1 is supported on the support platform 20. The outer end surface 21 of the support platform 20 is an inclined surface structure inclined from top to bottom toward the side away from the grouting head 24, which can improve the support performance. A longitudinal positioning column 22 and a transverse positioning column 23 are provided on the upper end surface of the support platform 20, and the transverse positioning column 23 is connected between the longitudinal positioning columns 22. The grouting head 24 is positioned between the longitudinal positioning columns 22 and the transverse positioning columns 23.

The longitudinal positioning column 22 and the transverse positioning column 23 can also be set in a form that can slide and adjust the position to match the grouting shallow pipes 1 of different diameters.

[0034] When in use, the transition connecting pipe 4 is threadedly connected to the shallow grouting pipe 1 and the deep grouting pipe 2, and the sealing performance of the connection is enhanced by the sealing fixing platform and the sealing body 9; the grouting pipe 10 is placed, and the grouting head 24 and the grouting port 25 on the shallow grouting pipe 1 are left outside the borehole, and an appropriate length is reserved; during low-pressure shallow hole grouting, the grouting hole 3 on the shallow grouting pipe 1 is slurried, and the grouting liquid expands through the high-pressure rubber hose 5 to seal the borehole gap and avoid leakage; after the shallow hole grouting is completed, the grouting pressure is increased, the high-pressure bursting valve 8 is broken, and the grouting liquid enters the deep grouting pipe 2 for deep hole grouting; during high-pressure deep hole grouting, a retarder is injected from the grouting port 25 through the retarding pipe 11, and at the same time, the retarder and the grouting liquid are fully mixed inside the transition connecting pipe 4 with a spiral pipe structure, which can prevent the slurry from coagulating prematurely and causing pipe blockage, and has a certain guarantee on the strength of the final setting time of the grouting liquid.
