摘要： PURPOSE: To reduce auger torque at the time of drilling due to a friction reducing effect, to improve earth removal efficiency, or to sufficiently reduce resistance at the time of erecting a precast pile in a bored precast pile construction method using mechanical drilling, whereby a precast pile can be buried and installed in the ground quickly and efficiently. CONSTITUTION: An earth auger 4 is lowered while being rotated to drill the ground E, and a bubble manufacturing plant 8 is operated concurrently with the above operation, whereby bubbles generated by a bubble generator 14 are ejected from the tip of the auger 4 through a swivel joint 6. The bubbles obtained by mixing air with an aqueous solution of water-soluble high polymer are different from the conventional bubbles obtained by using a surfactant or the like, and though the expansion ratio of the obtained bubbles is low, the tackiness and gravity are large so as to effectively reduce frictional resistance between soil particles, or between the soil particles and the earth auger 4 or a precast pile 20. Thus, the auger torque at the time of drilling can be reduced, and the earth removal efficiency can be improved, or the resistance at the time of erecting the precast pile 20 in a drilled hole 30 can be reduced sufficiently.

摘要： PURPOSE: To enhance the working efficiency by carrying out the works of producing and feeding bubbles to be mixed with the earth and sand from excavation and boring the ground while the fed bubbles are agitated and mixed with the earth and sand, and conducting the processing to remove the bubbles from the residual soil material from excavation, wherein the works and the processing are performed in one sequence of operations. CONSTITUTION: An auger 7 is sunk in rotation to bore the ground E, and a bubble producing plant 2 is operated. Bubbles are spouted out of the tip of the auger 7 and agitated and mixed with the earth and sand from excavation so that they are given a fluidity. As a result, attachment of the earth and sand to the auger 7 and stirring vanes 9' etc., is prevented, which reduces the friction resistance and allows the boring operation to be done quickly. After boring, the plant 2 is stopped while a stabilizer supply plant 3 is put in operation, and agitation and mixing are made while the stabilizer is discharged from the tip of the auger 7 so that a soil cement column is constructed. The residual soil material from excavation is stacked in a waste soil deposit pit 20, and after eliminating the bubbles by a bubble eliminating agent, is exhausted by a vacuum suction device 25. Thereby the agitating and mixing construction method using bubbles can be performed in one sequence of operations, and the efficiency therein can be enhanced.

摘要： PURPOSE: To facilitate fluidification of the earth and sand from excavation, prevent easily the attachment of the earth and sand to stirring wanes, and improve the working effectiveness even in case the ground of the construction site is of such a type that the fluidity of the earth and sand is likely to lower, for example a gravel ground, or likely to attach to the stirring vanes such as a hard clayey soil. CONSTITUTION: Augers 4 of a three-spindle auger machine 1 are sunk in rotation into the ground so as to bore it, and in parallel a bubble producing plant 8 is operated. At this time, valves 10, 11 are changed over to the injection line 8a side, and a swivel joint 6 is connected with the bubble side, and boring with agitation is made to the specified depth while bubbles are spouted out of the tips of the augers 4. In this operating condition, the bubbles from the auger tips 4 are mixed thoroughly with the earth and sand in agitation by the stirring action of augers 4 so that the earth and sand have a sufficient fluidity, and also the bubbles are intruded between the augers 4, screws 5 fixed thereto, stirring vanes 5', and the earth and sand from excavation so that attachment of the earth and sand is prevented.

摘要： PROBLEM TO BE SOLVED: To improve air leakage recovering efficiency. SOLUTION: There are provided an air leakage recovering apparatus 10 consisting of first and second air leakage recovering filters 22 and 24, first and third lifting pipelines 26 and 30, and a lifting means 34. The air leakage recovering filters 22 and 24 are placed immediately above a cutting edge 14 of a caisson main body 12. The first and third lifting pipelines 26 and 30 communicate with the filters 22 and 24, respectively. The pipelines 26 and 30 upward extend along a longitudinal axial direction of the main body, and open in an upper surface of the main body 12. Then, a lifting integrated pipe 36 opens in an opening, and the lifting means 34 communicates with the integrated pipe 36. When the lifting means 34 of the apparatus 10 is driven, ground water on the periphery of the filters 22 and 24 flows toward the filters, to thereby form an underground stream W on the periphery of the filters 22 and 24. When leaked air A rises up to an area where the underground stream W is created, even if rising speed of the leaked air A increases, the air can be absorbed and recovered in association with flow of the underground stream W.

摘要： PROBLEM TO BE SOLVED: To provide a method for protecting an opening portion. SOLUTION: This protective structure 20 is constituted of a ground improving body 14 generated in the ground to cover an opening portion 13 from the natural ground side and multiple rod-like tensile materials 16 extended and arranged in the ground improving body 14 to cross the opening portion 13. The ground improving body 14 is generated by the deep layer stirring/mixing method, for example, and multiple improved ground columns 15 formed when an injected impregnant and the sediment of the natural ground are mixed and stirred by stirring vanes are aligned and arranged horizontally and vertically to the width and thickness to cover the opening portion 13. The tensile materials 16 are made of a fiber-reinforced plastic such as glass fibers or carbon fibers, for example, and they are arranged at the prescribed position in the ground improving body 14 to be extended across the opening portion 13 and near the opening portion 13.
