[0002] At present, the excavation of pier foundations mainly relies on rotary excavation pile foundations or manual excavation. This method cannot quickly excavate pier foundations, and the work efficiency is extremely low.
When the pier foundation is excavated, there will often be a lot of mud, etc., which is an extra step of removing the mud, and this step is often carried out after the pier foundation is completed, that is to say, the pier foundation Excavation and mud extraction are carried out separately and step by step, which not only increases the construction volume, but also prolongs the construction time, thereby reducing work efficiency
Moreover, because the pier foundation and mud pumping are carried out separately and step by step, and in the process of excavating the pier foundation, groundwater often seeps out and gushes out. Therefore, this will cause certain disadvantages to the construction site and construction engineering. impact, thus lower security
