A bridge pier pier foundation excavation equipment

Abstract

The invention discloses pier foundation excavation equipment which comprises a cushion cap (1) and a two-way hydraulic device (2), wherein the two-way hydraulic device (2) is fixed on the cushion cap (1); the cushion cap (1) comprises a cushion cap body (11), a main shaft (12) and at least two support stabilizer blades (13); the at least two support stabilizer blades (13) are arranged at the lower part of the cushion cap body (11); the main shaft (12) runs through the middle of the cushion cap body (11) and can be detachably fixed on the cushion cap body (11); the bottom part of the main shaft (12) is connected and provided with a rotary excavating tool bit (5) through a universal rotating shaft (4); a mud pump (3) is arranged at the middle part of the main shaft (12); a mud flow channel (131) is arranged in the main shaft (12); and the mud pump (3) is communicated with the mud flow channel (131). Through the implementation of the pier foundation excavation equipment, the mid extraction process can be carried out in the pier foundation excavation process, so that not only is the work efficiency improved, and also the safety of a working environment is also ensured.

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
