Abstract

The invention provides an air supply device which comprises a plurality of vertical pipes and a fixing mechanism arranged among the vertical pipes. The fixing mechanism is arranged on the upper portions of the vertical pipes and is of a frame structural mode, and the tops of the vertical pipes are communicated with a high-pressure fan. A method for cleaning a bridge drilled pile head through the air supply device comprises the following steps of (1) placing the air supply device down to a designated elevation position in a steel casing; (2) enabling an air supply pipe and the high-pressure fan to be communicated and starting the high-pressure fan; (3) pumping out concrete which loses efficacy in the steel casing through a slime pump; and (4) carrying out secondary cleaning on concrete in the steel casing manually. The air supply device is simple in structure; the function of supplying air to the concrete in the steel casing is achieved through the vertical pipes, and smooth air supply is guaranteed. According to the method, the high-pressure fan supplies air through the vertical pipes of the air supply device, and therefore setting of cement in the steel casing is prevented, and the cleaning method saves time and labor.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to an air supply device and a method for cleaning bridge bored pile heads by using the air supply device. Background technique [0002] At present, the foundation design of large-span sea-crossing and river-crossing bridges adopts large-diameter bored piles. According to relevant construction specifications, in order to ensure the quality of pile foundations, overfilling is required during the pile filling process, which leads to the cleaning of pile head concrete in the later stage. The amount is relatively large, and the conventional method of pile foundation pile head is adopted, that is, after the final setting of the concrete, excavators and other construction machinery and manual chiseling are used to remove it. It takes a lot of construction machinery and manual work to complete the pile foundation pile head treatment under the premise of ensuring the constructio...
