Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0019] Such as figure 1 As shown, the housing 1 is a steel cylinder structure with the upper and lower ends closed, which may be composed of a cylinder body and a top cover, or may be composed of upper and lower halves. As an equivalent replacement, the housing 1 can be changed to a square or other suitable shape, and the material of the housing 1 can also be changed according to actual needs. At least one exhaust fan 2 is installed on the top of the housing 1. In this embodiment, there are four exhaust fans 2, and the four exhaust fans 2 are distributed in a rectangular shape. Of course, according to actual needs, only one or two or three exhaust fans can be installed.
[0020] Such as figure 1 As shown, the impeller shaft of the exhaust fan 2 is connected to the drive shaft of the motor, and the air outlet of the exhaust fan 2 is connected with an air ou...

The invention discloses a pile bottom cleaning device. A shell (1) is in a cylindrical structure with closed upper and lower ends; at least one exhaust fan (2) is arranged at the top of the shell (1); an impeller shaft of the exhaust fan (2) is connected with a driving shaft of a motor; an air outlet of the exhaust fan (2) is connected with an air outlet pipe (3); an air inlet of the exhaust fan (2) is communicated with the inner part of the shell (1); an air suction pipe (4) is connected with the peripheral side wall of the shell (1); and the air suction pipe (4) is communicated with the inner part of the shell (1). According to the pile bottom cleaning device disclosed by the invention, sediments on hole bottoms of various rotary excavation pile holes can be cleaned and can be tidily and completely cleaned; and the pile bottom cleaning device disclosed by the invention has the characteristics of simple structure, reasonable structure, low cost, convenience and fastness in operation, time saving and labor saving, good safety and the like; and the project quality can be effectively guaranteed and integral settlement of a floor layer is prevented.
Description
technical field [0001] The invention relates to a device for cleaning the bottom of a rotary drilling borehole. Background technique [0002] At present, with the rapid development of the construction industry, the pile holes on the construction site are gradually changed from traditional manual excavation to rotary excavator excavation. Due to the continuous acceleration of the urbanization process, there are more and more high-rise buildings, and the height of the building floors is also increasing, so the pile holes used for the foundation of the building floors are getting deeper and deeper. The use of rotary drilling will inevitably form stones, mud, slag, dust and other debris at the bottom of the pile. These sediments cannot be cleaned, and concrete is often poured directly without cleaning, which seriously affects the project. quality, it is easy to cause the overall sinking of the floor. Contents of the invention [0003] The technical problem to be solved b...
