摘要： PROBLEM TO BE SOLVED: To improve the excessive delivery of a ground improvement material and the flowrate eccentricity thereof, and make an easy selection between upper and lower delivery ports for the soil improvement material by forming the delivery ports at upper and lower positions on the central part of a tandem excavation and agitation head via the joint member thereof. SOLUTION: This device is formed out of a tandem excavation head 1 having an excavation weight 6 and an excavation blade 7 on the ends, and a plurality of agitation blades 8 projected from upper and lower positions on the sides, and rotatably jointed in parallel at upper and lower positions via joint members 4 and 5, as well as a pair of screw rods 3 with tubular soil improvement material feed passages 31 inside and connected to the excavation and agitation head 1 with the lower ends coupled to the upper end of each shaft 2. In addition, ground improvement delivery ports 9 and 10 are formed downward on the centers of the upper and lower joint members 4 and 5 of the excavation shafts 2. Thereafter, the delivery ports 9 and 10, and the feed passage 31 are connected to one another via a passage inside each excavation shaft 2, and the delivery ports 9 and 10 are arranged at upper and lower positions on the center of the excavation and agitation head 1.

摘要： PURPOSE:To realize an automatic flow control device by which fine flow control in a deep layer mixing and stirring process and the like is possible, and provide transport of stabilizing material of stable flow. CONSTITUTION:In this automatic flow control device, the controller is constituted by combining PID control (where P: proportion element, I: integration element, D: differentiation element), fuzzy control, and estimation control. Exact motor variable commands 8 are always output to a motor variable control device depending on the feedback from a flow meter. This device is constituted of a comparison control part 3, a PID + fuzzy inference control part 6, and a PID + fuzzy control part 7, and the material can be transported in stable flow by sampling at high speed the flow present value 5 and the flow pressure value 4, and computing them.
