The other end of the water pipe 45 is connected with a sprinkler through a pipeline, the sprinkler is positioned on one side of the top of the iron pipe 1, and the other end of the mud pipe 46 is connected with the grinding bin 22 through a pipeline; after the separation mechanism 4 separates river water and silt, the river water is separated to a water pipe 45 and is connected to a sprayer through the water pipe 45, under the continuous pumping pressure of the pumping mechanism 3, the river water continuously sprays water to the friction end of the polishing head 21 and the iron pipe 1, so that the polishing head 21 is effectively cooled, the overheating damage to the polishing head 21 caused by long-time polishing is avoided, the silt is separated to a mud pipe 46 and then pumped into the polishing bin 22, when the polishing head 21 continuously rotates, the hole plug 24 plugs the through hole, the silt pumped into the polishing bin 22 can be temporarily stored, after the polishing mechanism 2 finishes polishing, the rotation is stopped, the wind ball 25 and the connecting rod descend, the through hole is not plugged by the hole plug 24, and the silt in the polishing bin 22 can slowly flow out of the through hole under the action of gravity and also drip into the iron barrel below; thereby being used as a foundation for capping the iron pipe 1.

A tungsten wire mesh 11 is arranged in the iron pipe 1, and the tungsten wire mesh 11 is positioned below the side of the air inlet; after the grinding is finished, the sludge continuously drops downwards from the grinding bin 22, meanwhile, molten iron melted in the melting box 51 of the melting mechanism 5 on one side is also pumped out by the transmission assembly 52 and is uploaded to the port of the iron pipe 1, the molten iron drops inwards, part of molten iron which just begins to drop drops to the bottom layer inside the iron pipe 1 through the tungsten wire mesh 11, therefore, river water and sludge in the bottom layer inside the iron pipe 1 are pumped out, a main molten iron pipe is poured at the bottom of the iron pipe 1 and is continuously thickened, a liquid pumping hole is blocked, finally, the molten iron at the bottom is condensed into an iron block, the bottom of the iron pipe 1 is sealed, the density of the iron block is far greater than that of the river water and the sludge, so that a pile foundation at the bottom of the iron pipe 1 inserted into the river bottom is firmer and more stable, and the sludge gradually forms a tungsten wire mesh layer above the tungsten wire mesh 11 due to larger viscosity and adhesive force of the sludge, the subsequent molten iron that drips is difficult to break the tungsten filament mud layer to continue to save the molten iron above the tungsten filament mud layer, seal the inlet port, the molten iron condenses the iron plate at last, has realized the capping to iron pipe 1, has finally realized the effect of iron pipe 1 capping and back cover after polishing the completion, has increased its inside leakproofness, effectively prevents that iron pipe 1 is inside to take place the oxidation, has also reduced the degree of difficulty of building bridge engineering simultaneously.

The polishing mechanism 2 is of a detachable structure; after the capping is accomplished, because the molten iron drips and the 1 top unevenness of iron pipe that condenses into, grinding machanism 2 can trade polishing head 21 for the crew cut, advances once to polish at 1 top of iron pipe, has finally guaranteed that the 1 top surface of iron pipe after the capping is level and smooth, facilitates for the follow-up bridge of setting up.
