Description

Technical Field

[0001] The utility model relates to the technical field of foundation engineering, in particular to a distributed grouting device for a pile foundation. Background Art

[0002] Grouting technology can inject slurry into the soil around the pile or into the pile after pile foundation construction to increase the bearing capacity of the pile foundation, reduce settlement and improve the shear strength of the foundation.

[0003] Traditional devices have no fixing function, and the feed pipe is prone to loosening or shifting, resulting in the slurry not being accurately delivered to the main body. The feed pipe needs to be manually or temporarily fixed, which increases the complexity and uncertainty of the operation. The mixed air will cause the grouting pressure to be unstable, affecting the fluidity of the slurry and the continuity of construction, and may cause uneven or stagnant slurry flow.

[0004] Secondly, the operation is cumbersome. Without the quick connection function, the installation and removal of the pipes between the liquid storage tank and the grouting pump will take more time and manpower, increasing the complexity of the construction.

[0005] Finally, without the continuous stirring function of the mixing frame, solid precipitation or stratification is likely to occur when the slurry stays in the storage tank for a long time, resulting in uneven slurry injected into the pile foundation and affecting the reinforcement effect.

The fixing bracket 8 is installed on the connecting pipe 7 and is slidably connected to the connecting pipe 7. The threaded sleeve 10 is installed on the connecting pipe 7 and is slidably connected to the connecting pipe 7.

[0031] When the material is put into the tank 1, the fixing mechanism includes a material delivery pipe 2, a first spring 3, a fixing plate 4 and a tank cover 5. When in use, cement slurry needs to be input into the main body 1 first. At this time, the external material delivery pipe 2 is directly placed in the connecting base 15 on the tank cover 5. Before putting in the material delivery pipe 2, the fixing plate 4 installed on the connecting base 15 should be pulled first. At this time, the fixing plate 4 directly compresses the first spring 3. When the fixing plate 4 is pulled open, the material delivery pipe 2 is placed in the connecting base 15. At this time, the fixing plate 4 is released. The first spring 3 acts to cover the fixing plate 4 directly on the clamping plate 17 of the material delivery pipe 2, thereby fixing the material delivery pipe 2 to prevent the material delivery pipe 2 from shaking due to the pressure of the material during the feeding process. In the process of feeding, the cement slurry enters the main body 1 and compresses the air.

During the rotation of the connecting pipe 7, the positioning rod 26 enters the positioning hole 25. The stretched second spring 9 exerts force to push the positioning rod 26 into the positioning hole 25, thereby fixing the left and right shaking of the connecting pipe 7 on the discharge pipe 6. In the above process, the inner tube 27 enters the discharge pipe 6 and fits tightly with the discharge pipe 6.

At this time, the control valve 19 is opened, and the grouting pump 13 starts to operate. Through the connection of the main material pipe and the connecting pipe 7, the cement slurry is pumped out of the main body 1, and through other connecting pipes 7, the cement slurry is transported into the grouting pipe 14 to complete the grouting process of the pile foundation.

At this time, the connecting rod 23 and the connecting plate 24 slide in the sliding groove 22, and the positioning rod 26 on the fixing frame 8 first contacts the discharge plate 20, so that the fixing frame 8 is ejected and the second spring 9 is stretched. During the rotation of the connecting pipe 7, the positioning rod 26 enters the positioning hole 25, and the The stretched second spring 9 exerts force to push the positioning rod 26 into the positioning hole 25, thereby fixing the left and right shaking of the connecting pipe 7 on the discharge pipe 6. In the above process, the inner tube 27 enters the discharge pipe 6 and fits tightly with the discharge pipe 6. When the connecting pipe 7 and the discharge pipe 6 are connected, one end of the connecting pipe 7 and the grouting pump 13 can be installed at this time, and the threaded sleeve 10 is rotated on one end of the connecting pipe 7 and engaged with the thread of the grouting pump 13 to complete the connection of the other end of the connecting pipe 7. When the pipeline connection is completed, cement slurry is input into the inside of the main body 1.
