The slurry outlet areas at the left end and the right end of the grouting port 321 can divide slurry into two strands and convey the slurry into the holes, so that the plugging quality is improved.
Of course, in other examples, the number of the slurry outlet areas is not limited to the two slurry outlet areas, and the slurry can be dispersed more and more the slurry outlet areas are arranged by the structure of the flow dividing plate 4.
In a specific example, the diverter plate 4 may be rectangular, and the diverter plate with a rectangular shape is installed at the position, adjacent to the grouting opening 321, of the grouting piece 3 and divides the grouting opening 321 into two laterally symmetrical grouting areas, so that the grouting areas can be used for diverting the grouting material and simultaneously ensuring that the grouting materials conveyed by the two grouting areas are consistent.
In other examples, the diverter plate 4 may be cross-shaped, and the diverter plate with the cross shape is installed at the position of the grouting piece 3 adjacent to the grouting opening 321 and divides the grouting opening 321 into four grouting areas with equal areas, so that slurry is conveyed more dispersedly, and further, slurry is ensured to be better filled to the edge of the hole, and the plugging quality is improved.
In some embodiments of the application, the throttle area of the diverter plate 4 is equal to 90% to 110% of the difference between the cross-sectional area of the connecting tube 2 and the cross-sectional area of the grouting channel 311. The splitter plate 4 is arranged adjacent to the grouting opening 321, the splitter plate 4 can enable the cross section area of the connecting pipe 2 to be approximately equal to the cross section area of the grouting channel 311, the consistency of the slurry flowing through the connecting pipe 2 and the slurry flowing out of the grouting channel 311 is ensured, and the consistency of slurry conveying is improved.
Alternatively, the grouting passage 311 has a cross-sectional area equal to that of the grouting port 321. Here, the throttle area of the flow dividing plate 4 is equal to 90% -110% of the difference between the cross-sectional area of the connecting pipe 2 and the cross-sectional area of the grouting opening 321, when the slurry conveyed by the connecting pipe 2 is conveyed to the grouting opening 321, the slurry can fill the grouting opening 321, so that the consistency of the slurry flowing through the connecting pipe 2 and the slurry flowing out of the grouting opening 321 is ensured, and the consistency of the slurry conveying is improved.
Advantageously, the throttle area of the diverter plate 4 is equal to the difference between the cross-sectional area of the connecting pipe 2 and the cross-sectional area of the grouting openings 321. As can be seen from fig. 2 and 3, the diameter of the connecting pipe 2 is smaller than the diameter of the grouting channel 311, and the slurry is reduced when being conveyed from the connecting pipe 2 to the grouting channel 311, so that if the splitter plate 4 is not provided, the slurry cannot completely fill the grouting channel 311 when being conveyed to the grouting port 321 through the connecting pipe 2, which is particularly obvious for the case of thick slurry, and further, gas enters the slurry in the grouting channel 311 through the grouting port 321, thereby affecting the plugging quality. The application can compensate the difference between the cross section area of the connecting pipe 2 and the cross section area of the grouting channel 311 by arranging the flow dividing plate 4, so that the cross section area of the grouting opening 321 is equal to the cross section area of the connecting pipe 2, and the flow dividing plate 4 can discharge the gas in the slurry, and ensure the consistency of the slurry flowing through the connecting pipe 2 and the slurry flowing out of the grouting opening 321, thereby ensuring the plugging quality.
