Problems solved by technology
[0002] With the further improvement of domestic real estate construction requirements, high-rise buildings have higher and higher requirements for pile foundations, which require a large bearing capacity. In the process of working, the threaded pile drilling tools in the prior art form threaded holes by squeezing the soil, which cannot Take out the soil in time, and pouring can only be done after taking out the drilling tool. When the drilling tool is taken out, the soil is easy to fall off, affecting the depth and structure of the threaded hole, resulting in the quality of the threaded pile poured later

The invention discloses a pile-forming device for threaded piles. The pile-forming device includes a threaded rod, the threaded rod includes a first support pipe, and a soil-discharging member is arranged inside the threaded rod, and the soil-discharging member includes a soil-discharging pipe body; the threaded rod A supporting connector is provided on the top, and the supporting connector includes a supporting main body. A feeding pipe is arranged on the supporting main body, and a second counterbore is provided under the supporting main body at one end of the feeding pipe. The pile-forming device of the present invention discharges the soil in time through the soil discharger, reduces the depth of threaded piles caused by excessive soil, and ensures the quality of the threaded piles; realizes simultaneous pouring during the lifting process of the threaded rods, and promptly removes the threaded rods The formed threaded holes are poured and filled to avoid soil falling off due to the separation of the threaded rod and the soil to fill the threaded holes, improve the pouring efficiency of the threaded piles, and improve the pouring quality.
Description
technical field [0001] The invention relates to a pile-forming device and a pile-forming method, in particular to a pile-forming device and a pile-forming method for threaded piles. Background technique [0002] With the further improvement of domestic real estate construction requirements, high-rise buildings have higher and higher requirements for pile foundations, which require a large bearing capacity. In the process of working, the threaded pile drilling tools in the prior art form threaded holes by squeezing the soil, which cannot Timely take out the soil and take out the drilling tool before pouring. When the drilling tool is taken out, the soil is easy to fall off, affecting the depth and structure of the threaded hole, resulting in the quality of the threaded pile poured later. Contents of the invention [0003] The purpose of the present invention is to provide a pile-forming device and pile-forming method for threaded piles, which can discharge the soil in time ...
