Abstract

The invention provides a sediment cleaning device and a cast-in-place pile hole sediment cleaning method with the expanding head. The device comprises a reverse pulp guide pipe, a first air supply guide pipe and a stirring mechanism, wherein one end of the reverse pulp guide pipe is open; the reverse pulp guide pipe is arranged in the pile hole, an output opening is formed in the closed end of thereverse pulp guide pipe, and a first preset distance is formed between the opening end of the reverse pulp guide pipe and the bottom of the pile hole, and the reverse pulp guide pipe is used for conveying slurry and sediment in the pile hole to the ground; the first air supply guide pipe is arranged at the closed end of the reverse pulp guide pipe in a penetrating mode and is partially arranged inside the reverse pulp guide pipe, and the first air supply guide pipe is used for conveying compressed air; and the stirring mechanism is at least partially arranged in the pile hole, the stirring mechanism is used for stirring slurry in the pile hole, and the slurry is used for driving the sediment to be conveyed into the grouting guide pipe. According to the sediment cleaning device and the cast-in-place pile hole sediment cleaning method with the expanding head, the purpose of cleaning the sediment in the pile hole can be effectively achieved, so that the sediment cleaning is further guaranteed, and meanwhile, the cleaning device is suitable for any pile hole., and can meet relevant design requirements.

Description

technical field [0001] The invention relates to the technical field of pile holes, in particular to a sediment cleaning device and a method for cleaning sediment in cast-in-place pile holes with an enlarged head. Background technique [0002] At present, according to the relevant construction requirements, the cast-in-situ mud retaining pile can include: the cast-in-situ mud retaining pile with an enlarged head and the ordinary cast-in-situ mud retaining pile without an enlarged head. Wherein, the mud retaining cast-in-place pile with an enlarged head refers to reaming the hole bottom of the mud retaining cast-in-place pile so that the bottom of the hole forms an enlarged head. Generally speaking, the sediment cleaning at the bottom of the mud retaining cast-in-place pile usually adopts the positive circulation, reverse circulation pumping method or air pressure reverse circulation method. Construction requirements, however, for cast-in-situ piles with mud retaining walls w...
