Abstract

The invention relates to the field of ultra-large-diameter manual digging piles, in particular to a digging pile hole opening lifting protection device. The lifting protection device comprises a movable base and a lifting device arranged on the movable base. A digging pile hole opening is provided with a sliding way. The movable base is matched with the sliding way and can slide along the sliding way. During earth cutting construction, the movable base slides towards the edge of the digging pile hole opening along the sliding way, and the digging pile hole opening is open. Abandoned soil is lifted through the lifting device, and when earth cutting operation is stopped, the movable base slides towards the middle of the digging pile hole opening along the sliding way, and the digging pile hole opening is closed. According to the scheme, the problem that the work efficiency of the lifting device is low can be solved, and the safety problem that when the earth cutting operation is stopped, workers or other articles are likely to fall into an opened well mouth can be solved.

Description

technical field [0001] The invention relates to the field of super-large-diameter manual hole-digging piles, in particular to a lifting protection device for hole-digging pile openings. Background technique [0002] In the prior art, the excavation process for super-large-diameter manual excavation piles is as follows: [0003] (1) The excavation operation adopts manual excavation layer by layer, which is carried out layer by layer with picks and shovels. When hard soil layers and weathered bedrock are encountered, they are broken with hammers, brazing or pneumatic picks. The order of excavation in the same section is to dig the middle first. part of the rear perimeter. The spoil is loaded into the bucket and lifted to the orifice by the lifting equipment. [0004] (2) Manual excavation piles are excavated in sections and supported in sections. The excavation depth of each section is 0.65m, and 70mm thick concrete is sprayed immediately after every 30cm of excavation to f...
