Description

Technical Field

[0001] The utility model relates to the technical field of mixing pile construction devices, in particular to a blade soil cleaning device for a mixing pile machine. Background Art

[0002] Mixing pile is a method used to reinforce saturated soft clay low foundation. The construction process of mixing pile is: drilling holes in the ground through a mixing pile machine, breaking the soft soil in the hole, and then adding a curing agent (cement) to the broken soft soil, and forcibly stirring it, so that a series of physical and chemical reactions between cement and soft soil are used to consolidate the soft soil, and a cement soil pile with integrity, water stability and certain strength is formed in the drilled hole. During the construction, the mixing pile machine mixes the soft soil and cement through the mixing shaft and the blades (the blades are the mixing blades of the mixing shaft) arranged at the end of the mixing shaft. In this process, the soft soil and cement will adhere to the blades and solidify on the surface of the blades, which will increase the thickness of the blades and increase the stirring resistance. Therefore, the blades at the end of the mixing shaft need to be cleaned regularly. At present, the cleaning process of the mixing pile machine blades requires the staff to use a water spray pipe to spray water on the blades. This process is time-consuming and labor-intensive, inefficient and difficult to clean, and the water sprayed cannot be collected, which easily causes sewage to overflow and pollute the construction site.
