The purpose of the invention can be realized by the following technical scheme:
a hole bottom vacuum cleaning device after pile foundation construction comprises a guide pipe arranged in a pile foundation hole, wherein hole bottom sediments to be cleaned are arranged at the bottom end in the pile foundation hole, a side wall, close to the bottom end, of the guide pipe is communicated with an inclined pipe which is arranged in a downward inclination mode, the bottom end of the guide pipe is arranged in the hole bottom sediments, a gap is reserved between the bottom end of the guide pipe and the bottom end of the pile foundation hole, and an elbow is arranged at the upper end of the guide pipe;
and an air pressure pipe is hermetically arranged on the outer wall of the inclined pipe, and the other end of the air pressure pipe is hermetically connected with an air outlet of the air compressor.
Furthermore, water is accumulated in the pile foundation hole, and the height of sediment at the bottom of the hole is lower than that of the water surface.
Furthermore, the bottom end of the guide pipe is provided with a slag inlet, and the end part of the elbow is provided with a slag outlet.
Furthermore, the upper end of the guide pipe is fixedly connected through a hoisting rope on the crane.
The invention has the beneficial effects that:
when the device is used, the connected guide pipe and the air pressure pipe are placed into a pile foundation hole to be cleaned by using the crane, the upper end of the guide pipe is fixedly connected by a hoisting rope on the crane, the bottom of the guide pipe is close to the bottom sediment of the hole, the air compressor is started to pressurize compressed air into the guide pipe, the upward compressed air is used for taking the sediment out of the pile foundation, the air negative pressure principle is used, the sediment with the diameter smaller than that of the guide pipe can be cleaned, the position and the height of the guide pipe need to be continuously changed by using the crane during cleaning, the comprehensive cleaning is realized, the cleaning efficiency is improved, and the working time is reduced.
Drawings
The invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is an enlarged schematic view taken at A of FIG. 1 in accordance with the present invention;
