摘要： PROBLEM TO BE SOLVED: To provide an agitation wing of a continuous underground wall auger capable of efficiently agitating excavated soil and cement milk at the agitation section by changing the agitation wing even if an excavation diameter in the ground is changed by mounting the agitation wing on a rod side in a replaceable manner and being easily kept for reuse. SOLUTION: The agitating wing 5 of excavation stirring member of the continuous underground wall auger connected to the lower end of a rod of the auger is formed in a single body having a detachable fitting groove 13 on the side of an excavated rod 3. A mounting substrate 11 is projected to a required place of the rod side. The agitating wing 5 is mounted on the rod side every time when the excavation diameter is changed in a replaceable manner by fitting of the mounting substrate 11 to the agitating wing 5 and bolting.

摘要： PROBLEM TO BE SOLVED: To contrive the simplification and reliability of a changeover means by changing over a flow inlet of a supply line internally provided double at the upper part of a screw rod by the vertical movement of a change over cylinder. SOLUTION: Supply lines 11 and 12 of a ground improvement material is internally provided double from a screw rod 3 whose upper end is connected to a rotary drive means to a excavation agitation rod on the lower end. The discharge openings 13 and 14 of the supply lines 11 and 12 are provided on the upper and lower side surfaces of the excavation agitation rod. The flow inlets 13 and 14 of the supply lines 13 and 14 are provided at the upper and lower parts of the upper side surface of the screw rod 3. An introduction pipe 15 is provided downward from the upper end of the screw rod 3 to the outside of the rod right over the flow inlet. A change over cylinder 17 having an upward relay pipe 16, which connects the introduction pipe 15 and the flow inlets 13 and 14 alternately, is fitted in on the outer periphery of the upper part of the screw rod 3 so that it may move vertically freely, thereby fitting the relay pipe 16 in the introduction pipe 15 slidably. The lower side area of the change over cylinder 17 is held turnably with an operation member 19 while the operation member 19 is connected to a change over operation device 22 on the side of the rotary drive device.

摘要： PROBLEM TO BE SOLVED: To achieve a reduction in the weight of an apparatus and an increase in the working efficiency of shallow-ground improvement of soft ground by collectively holding four drilling rods by a holding base so as to enable the shared use of a drive unit for the drilling rods.
SOLUTION: The four hollow drilling rods having a drilling head at its leading end provided with an drilling blade, an agitating blade and an ejection port are held on the four sides of the holding base. The four hollow drilling rods are rotated by one or two common motors so as to penetrate soft ground. A soil improving material is ejected into excavated soil from a leading end of the rod through the drilling rod. The ground and the soil improving material are agitated and mixed together by means of the drilling blade.

摘要： PURPOSE: To prevent the rotational difference of both excavating rods by constituting a device for biaxially synchronized rotation so as to be interposed among a pair of the excavating rods and a driving device, and to eliminate a stepped section to be produced in the excavation in an improved ground by using excavation blades mounted at the same height places. CONSTITUTION: A device for biaxially synchronized rotation is composed of hollow rotation shafts 2 connected at the upper ends of each excavating rod of a two-throw auger device having a pair of excavating rods in biaxial parallel, a pair of transmission gears 3 being installed to the shafts 2 and having a large diameter, a pair of synchronization gears 4 being mutually engaged between both transmission gears and being disposed together with a support shaft 5 and having a small diameter and cases 8, which rotatably bear the shafts 2 and the support shaft 5 by bearing members 6, 7 and in which the shafts 2 and the support shaft 5 are stored. Lower joints 10 with the excavating rods are extended at the lower ends of the shafts 2. Upper joints 11 with a driving device are elongated at upper ends.

摘要： PURPOSE:To reduce the cost of construction by placing ready-mixed concrete from the tip of an excavator into a pile pit with residual excavated soil. CONSTITUTION:A pile pit 11 with residual excavated soil 10 is excavated by using an excavator 1 having a screw 3 on its tip. Ready-mixed concrete 12 is placed from the tip of the excavator 1 while moving it upwards, and a steel tube 13 is inserted into the concrete 12 to form a pile body 15. The construction cost can thus be further reduced than the conventional methods because of no-use of bentonite mud water.
