[0001] The utility model relates to the technical field of spiral earth-collecting devices, in particular to an adjustable PHC pipe pile core spiral earth-collecting device. Background Art

[0002] At present, many projects use PHC piles as foundation support bearing structures. Most PHC piles are hollow pipe piles (BS-011-2010). When piling, some pile cores will have soil squeezed in them, and the soil will fill the pile core. When backfilling the pile hole, the backfill soil will fill the pile core. According to the engineering design requirements, the foundation pile head is generally treated with core pouring. Then it is necessary to clean the pile core filled with soil, and then put down the steel cage and pour the pile core. Usually, the pile core treatment should meet the design of 1-2m depth. The inner diameter of the pile core is small (200mm-570mm), and it is impossible to use machinery. Soil can only be taken manually by digging scoops. A spiral earth taker is needed in the process of taking soil.

[0003] Most of the spiral earth extractors in the prior art are of an integral structure, and their overall length is mostly not adjustable, so that they cannot meet the requirements of soil extraction at a greater depth. Some spiral earth extractors are divided into three parts: a handle, a pipe section and a spiral drill bit, and multiple pipe sections are connected by threaded connections to achieve the purpose of adjusting the length of the spiral earth extractor. However, this method will cause stress on the screw thread during the soil extraction process and the screw thread is easily damaged. If the screw thread is damaged during use, the pipe section will fall off, affecting the service life of the spiral earth extractor and the normal soil extraction process. Therefore, an adjustable PHC pipe pile core spiral earth extractor is needed to solve the above problems. Utility Model Content
