[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, this embodiment discloses a steel structure foundation gap grouting device, including a trolley 1, on which a mixing tank 2, an air supply device 3 and a high-pressure grouting tank 4 are arranged. The mixing tank 2 is fixed to the trolley 1 by a plurality of legs. A feeding port 5 and an air motor 6 are arranged on the top of the mixing tank 2. A cover 7 is arranged on the feeding port 5. The feeding port 5 and the cover 7 can adopt the structure of a manhole. The air motor 6 is connected to the air supply device 3 through an air duct. A stirring paddle 8 is arranged in the mixing tank 2. The upper end of the stirring paddle 8 is connected to the air motor 6 by power.

[0018] The high-pressure grouting tank 4 is located below the mixing tank 2. The high-pressure grouting tank 4 is fixed on the support legs. The top of the high-pressure grouting tank 4 is provided with an air inlet 9 and a material transfer pipe 10. The air inlet 9 is connected to the air supply device 3 through an air passage. The upper end of the material transfer pipe 10 is connected to the mixing tank 2. The material transfer pipe 10 is provided with a first material valve 11. The top of the high-pressure grouting tank 4 is also provided with a pressure gauge 17. The pressure in the high-pressure grouting tank 4 can be checked through the pressure gauge 17. The bottom of the high-pressure grouting tank 4 is provided with a discharge pipe 12, and the discharge pipe 12 is provided with a second material valve 13.

[0019] In this embodiment, the air supply device 3 is an air pump air compressor, which is generally driven by electricity. Its connecting wires can be wound around a wire take-up device 14 , and the wire take-up device 14 is installed at the rear of the trolley 1 .

[0020] In this embodiment, a column 15 is provided at the front of the trolley 1, and a hook 16 is provided on the column 15. When the grouting pipe 18 is not in use, it can be hung on the hook 16 after being wound.

[0021] In this embodiment, the lower parts of the mixing tank 2 and the high-pressure grouting tank 4 are both constricted, which facilitates the grouting material to gather at the bottom.

[0022] The working principle of this utility model:

[0023] First, open the cover 7 on the feeding port 5, add grouting raw materials and water in proportion to the mixing tank 2, cover the cover 7, and the air supply device 3 provides an air source to drive the pneumatic motor 6 to drive the stirring paddle 8 to stir the grouting material. After the grouting material is evenly stirred, open the first material valve 11, and the grouting material flows into the high-pressure grouting tank 4 by gravity. Then close the first material valve 11, and the air supply device 3 provides an air source to inject high-pressure gas into the high-pressure grouting tank 4. The discharge pipe 12 is connected to the grouting pipe 18 and the second material valve 13 is opened to realize the grouting construction of the gap.

[0024] During the grouting process, the cover 7 on the feeding port 5 can be opened again, and the grouting raw materials and water can be added to the mixing tank 2 in proportion for stirring. After the grouting material in the high-pressure grouting tank 4 is used up, the slurry can be immediately injected into the high-pressure grouting tank 4 without waiting for stirring.

[0025] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
