A bridge pier pier foundation excavation equipment

Abstract

The invention discloses an excavation device of a bridge pier foundation. The excavation device comprises a bearing platform (1) and a bi-directional hydraulic device (2) fixed to the bearing platform (1), wherein the bearing platform (1) comprises a bearing platform body (11), a main shaft (12), and at least two supporting feet (13) arranged below the bearing platform body (11); the main shaft (12) penetrates through the middle of the bearing platform body (11), and is detachably fixed to the bearing platform body (11); a rotary excavation cutting head (5) is connected and arranged at the bottom of the main shaft (12) through a universal rotating shaft (4); a slurry pulp (3) is arranged in the middle of the main shaft (12); a slurry circulation channel (131) is arranged inside the main shaft (12); and the slurry pulp (3) communicates with slurry circulation channel (131). Through the implementation of the excavation device of the bridge pier foundation, the slurry pump removing process can be carried out during the pier foundation excavation process, so that the working efficiency is improved, and the working environment is guaranteed to be safe.

Description

technical field [0001] The invention relates to the construction field, in particular to a bridge pier pier foundation excavation equipment. Background technique [0002] At present, the excavation of bridge pier foundations mainly relies on rotary excavation of pile foundations or manual excavation. This method cannot quickly excavate bridge 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 additional 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 fou...

Problems solved by technology

[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
