Definitions

  • the excavation resistance can be efficiently reduced according to the change in the ground properties, so that the diameter of the improved diameter can be increased without impairing the advantages inherent in the powder system (in other words, improved If the diameters are the same, it is possible not only to reduce the size of the construction machine, such as the size of the drive device), but also to reduce the construction cost. In particular, it is important to be able to cope with a wide range of soil changes by controlling both the concentration and the injection amount.
  • the control in the form (a) is preferable.
  • the form (c) is suitable when the effect of improving the fluidity is gradually exhibited.
  • the control in the form (b) is preferable. Therefore, it is also a preferable form to appropriately combine the forms (a) to (c) like the form (d).
  • a tip liquid jet port 17 is formed at the tip (lower end) of 101. Further, in the main body shaft 101, an agitation unit powder channel 102 that forms an internal powder line L1 and an agitation unit liquid channel 103 that forms an internal liquid line L2 are formed. Among these, the stirring part powder flow path 102 extends from the upper end of the main body shaft 101 to the front end side and branches into two flow paths, one on the side surface of the axial position corresponding to the lower powder injection port 12. , And the other is opened on the side surface of the axial position corresponding to the upper powder injection port 15.
  • the agitation shaft 10 is excavated and penetrated into the ground to improve the fluidity of the improvement target part, and then the powdered solidified material is injected into the fluidity improvement part G and agitated by the agitating blades 13 and 14.
  • the control device 50 operates the stock solution pump 42 and the dilution water pump 44 of the fluidity improver supply device 40 to pump the fluidity improver aqueous solution from the fluidity improver supply device 40, and the external liquid line L 12.
  • the internal liquid line L2 as shown in FIG.
