An uplift-resistant table ring groove excavation device for uplift-resistant piles

Abstract

The invention discloses an anti-pull-out table ring-groove excavation device for an anti-pull pile. The motor is arranged vertically, and at least two upper annular water jacket mounting brackets are arranged on the body of the excavating motor, and an annular water jacket is installed on the upper annular water jacket mounting bracket; the water inlet pipe, the slurry discharge pipe and the annular water jacket The inlet and outlet pipes pass through the upper annular water jacket mounting frame in sequence from the outside of the excavating motor, the ports of the water inlet pipe and the slurry discharge pipe are arranged above the excavating fan blade, and the ports of the annular water jacket inlet and outlet pipes are connected to the upper sealing ring sleeve, and the upper annular water jacket is installed The annular water jacket in the frame is connected with the inlet and outlet pipes of the annular water jacket through pipes; the annular water jacket in the lower annular water jacket mounting frame is communicated with the lower sealing ring sleeve through pipes. The problem of how to excavate the ring groove of the anti-uplift table on the basis of the circular pile hole is solved.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to an uplift-resistant platform ring groove excavation device for uplift-resistant piles. Background technique [0002] Anti-uplift piles are also called anti-floating piles, which refer to the piles that are driven to offset the buoyancy of the structure generated by the water in the soil when the underground structure of the construction project is lower than the surrounding soil water level. [0003] In order to make the piles have greater anti-buoyancy, engineers have designed uplift piles with various structures. The simplest type of uplift pile is a cylindrical pile that is driven underground. This pile structure is easy to implement. ,is widely used. In order to make the cylindrical structure pile body have greater buoyancy resistance, a plurality of annular anti-uplift platforms can be set on the cylindrical structure pile body, and these annular anti-uplift platforms ...
