[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

The invention discloses a bridge pier foundation excavating device which comprises a bearing table (1) and bidirectional hydraulic devices (2) fixed to the bearing table (1). The bearing table (1) comprises a bearing table body (11), a main shaft (12) and at least two supporting feet (13) arranged below the bearing table body (11). The main shaft (12) penetrates the middle of the bearing table body (11) and is detachably fixed to the bearing table body (11). The bottom of the main shaft (12) is provided with a rotary excavating tool bit (5) in a connected manner through a universal rotating shaft (4). A slurry pump (3) is arranged in the middle portion of the main shaft (12). A slurry circulating channel (131) is arranged in the main shaft (12). The slurry pump (3) communicates with the slurry circulating channel (131). By the implementation of the bridge pier foundation excavating device, the process of removing slurry through extraction can be conducted while the bridge pier excavating process is conducted, the working efficiency is improved, and the safety of the working environment is also ensured.
