Reducing swing-injected agitating pile
The invention relates to a reducing swing-injected agitating pile. Stirred cement paste is pressed into a cement paste tube through a slurry pump. The cement paste enters a faucet through a cement paste pipe connector, then enters a grouting steel tube and is sprayed out through a high-pressure slurry sprayer, and a soil body is cut at high pressure. While the soil body is cut through high-pressure cement paste, reducing stirring blades arranged on an outer drill pipe and an inner drill pipe can synchronously achieve stirring of the soil body. While the soil body is cut through a high-pressure grouting mode and the stirring blades of the inner and outer drill pipes rotate to stir the soil body, under the action of a lifting system, the whole high-pressure grouting and stirring system carries out grouting, stirring and sinking at the same time or stirring and uplifting at the same time according to design requirements. By means of a series of motions, the cement cylindrical agitating pile with a certain diameter can be obtained. On the basis that the advantages that a construction machine is simple and speed is high in a deep layer stirring method are inherited, the comprehensive advantages that a high-pressure swing-injection method is large in guniting pressure, wide in applicable stratum range and large in three-axis agitating pile power are combined, and the agitating pile has the characteristic of being wide in application range.
