[0002] With the continuous development of social economy and the increasing improvement of scientific and technological level, my country's construction industry is also developing continuously. Concrete pipe piles, as tubular structural materials placed after drilling or digging in the soil, are usually used in construction projects as a kind of structure for foundation reinforcement and foundation support, and pipe pile centrifugal is an important link in the production process of concrete pipe piles.
[0003] There is a pipe pile centrifugal device in the prior art, which includes a machine body, on which a rotating mechanism and a pipe pile mold are arranged, and the pipe pile mold includes an upper pipe pile mold and a lower pipe pile mold. The upper pipe pile mold and the lower pipe pile mold are connected by bolts, and a residual slurry hole is opened on one end of the pipe pile mold along its own length direction, and the residual slurry hole is connected to the inner chamber of the pipe pile mold. The rotating mechanism is used to drive the pipe pile mold to rotate along its own axis. When in use, the rotating mechanism drives the pipe pile mold to rotate, so that the concrete in the pipe pile mold performs high-speed centrifugal motion to make a hollow concrete pipe pile, and then the relevant personnel move the pipe pile mold to the outside of the machine body through other equipment, and then discharge the excess residual slurry by tipping the pipe pile mold, and then proceed to the next process after discharge.
[0004] Regarding the above-mentioned related technologies, since there is gas in the pipe pile mold, when the rotating mechanism controls the pipe pile mold to rotate, the gas in the pipe pile mold will enter the concrete, so that there are tiny bubbles in the concrete after the pipe pile is centrifuged, which reduces the density of the pipe pile after molding, thereby reducing the quality of the pipe pile. Utility Model Content
[0005] In order to improve the compaction effect of pipe piles, the present application provides a pipe pile negative pressure grouting device.
[0006] The present application provides a negative pressure grouting device for a pipe pile, which adopts the following technical solution:
[0007] A negative pressure grouting device for pipe piles comprises a negative pressure pipe, one end of which is used to communicate with the residual slurry hole on the pipe pile mold, and the other end of the negative pressure pipe is also provided with an upper extension pipe, one end of the upper extension pipe is connected to the negative pressure pipe, and the other end of the upper extension pipe is connected to a negative pressure vacuum pump.
[0008] By adopting the above technical solution, the negative pressure tube and the negative pressure vacuum pump are arranged so that the negative pressure vacuum pump can be connected to the pipe pile mold through the upper extension tube and the negative pressure tube, so that the negative pressure vacuum pump can evacuate the chamber in the pipe pile mold and form a negative pressure, so that the tiny bubbles in the concrete after centrifugation in the pipe pile mold are extracted from the concrete, thereby improving the density of the pipe pile after molding and improving the quality of the pipe pile.
[0009] Preferably, one end of the negative pressure pipe away from the pipe pile mold extends outward and is connected to the outside world. A residual slurry valve is also provided on the end of the negative pressure pipe away from the pipe pile mold, and the residual slurry valve is used to control the opening and closing of the end of the negative pressure pipe.
[0010] By adopting the above technical solution and setting the extension of the negative pressure tube, when the residual slurry in the pipe pile mold needs to be dumped, the relevant personnel can control the residual slurry valve to open, so that the residual slurry in the pipe pile can pass out through the negative pressure tube.

The existence of the sliding frame and the rotating frame also effectively ensures the stability of the guide bucket when it stops.
[0017] Preferably, the driving assembly includes a driving member and a driving screw, the driving screw is rotatably connected to the mounting frame, one end of the driving screw passes through the guide bucket and is threadedly connected to the guide bucket, and the driving member is used to drive the driving screw to rotate.

A filter is also provided on the end of the upper extension tube connected to the negative pressure tube.
[0022] By adopting the above technical scheme, the setting of connecting the upper extension pipe with the top of the negative pressure pipe effectively reduces the probability of the residual slurry accidentally flowing into the upper extension pipe when the residual slurry passes out through the negative pressure pipe, thereby effectively ensuring the smooth operation of the negative pressure vacuum pump. At the same time, the presence of the filter net can further reduce the probability of the residual slurry accidentally flowing into the upper extension pipe.
