A bridge pier pier foundation excavation equipment

Abstract

The invention discloses pier foundation excavation equipment for a pier. The pier foundation excavation equipment comprises a bearing platform (1) and a bidirectional hydraulic device (2), wherein the bidirectional hydraulic device (2) is fixed on the bearing platform (1); the bearing platform (1) comprises a bearing platform main body (11), a main shaft (12), and at least two supporting legs (13) which are arranged at the lower part of the bearing platform main body (11); the main shaft (12) penetrates through the middle part of the bearing platform main body (11), and is fixed on the bearing platform main body (11) in a detachable manner; a rotary excavating cutter bit (5) is arranged at the bottom part of the main shaft (12) in a connecting manner through a universal rotary shaft (4); a slurry pump (3) is arranged in the middle part of the main shaft (12); the main shaft (12) is internally provided with a slurry circulation channel (131); the slurry pump (3) is communicated with the slurry circulation channel (131). By implementation of the pier foundation excavation equipment for the pier disclosed by the invention, the pier foundation excavation process and the slurry pumping process can be performed simultaneously, so that not only is the working efficiency improved, but also the safety of the working environment is guaranteed.

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
