摘要： PURPOSE: To increase the efficiency of the earthquake-resisting reinforcement of a foundation by providing a vertical hole on the side of an existing foundation, injecting a hardening agent within a relatively wide range just under the existing foundation through this hole, and forming a columnar foot protection part to reinforce the circumference of a foundation pile. CONSTITUTION: A ground improving vertical hole 2 is drilled from the side of an existing foundation 1, a pipe 3 as a rod is inserted to this vertical hole 2 by use of a constructing machine 6, and a suspension type chemical or a cement solidifying agent or cement milk hardener is injected from the lower end of the pipe 3. At the injection of the solidifying agent, it is sprayed at a super-high pressure to cut the ground, and the soil grains and the hardener are mixed and stirred, or a columnar foot protection part 4 is formed within a relatively wide range just under the existing foundation 1 by substitution. This method can be applied when a pile head is broken by an earthquake. The circumference of a foundation pile 5 is reinforced to reinforce the horizontal supporting force at earthquake. Thus, an earthquake-resisting reinforcement can be executed with a simple method.

摘要： PURPOSE:To increase the degree of freedom for the construction plan of a building and reduce the construction cost by forming a plurality of subsoil improvement bodies of large bore in a weak subsoil immediately under a building foundation, and jointing the foundation under tension to the improvement bodies with ground anchors. CONSTITUTION:A pit is drilled under a building foundation and a pipe 2 is inserted therein. In addition, an ultra-high jet flow containing a curing agent is blown underground via the pipe 2 and a columnar soil improvement body 3 of large bore is formed with the agent and sediment, while the surrounding ground is being drilled. Before the improvement body 3 is cured, a ground anchor tension member 6 and the underground fixing body 4 of a ground anchor are buried in the body 3. After the improvement body 3 is cured and the strength thereof is realized, a building foundation 7 as constructed and the improvement body 3 are jointed to each other under tension with the tension member 6 tightened, thereby fixing the foundation 7 to the improvement body 3. According to this constitution, the degree of freedom for the construction plan of a building can be increased, compared with the conventional method, and the construction cost can also be reduced, compared with the conventional foundation piling method.

摘要： PURPOSE:To enhance the workability for increasing the bearing force of an existing base. CONSTITUTION:A shaft 2 is drilled in the foundation around or through an existing base 1, and a guide pipe 3 is inserted into the shaft 2. Ultrahigh pressure jet water containing hardener is injected into the underground through the guide pipe 3 so as to mix the hardener and sediment together obtained by cutting the foundation around the guide pipe 3. Then, thus obtained mixture is then directly hardened so as to form a foot protection part 4 underneath the bottom surface of the existing base 1, the foot protection part 4 having a planar area which is larger than that of the existing base 1. With this arrangement, a necessary bearing force may be ensured so as to eliminate the necessity of troublesome work for building a new base, thereby it is possible to enhance the workability and to shorten the construction period.

摘要： PURPOSE: To use a foundation as an earth retaining wall to save labors and cost in the construction, by filling back slime discharged during stabilization of soil into the periphery of building foundation and forming a solidified body of slime, when a solidifying agent is injected into a soft ground to erect a building. CONSTITUTION: An earth retaining wall 2 is constructed around the area where a building is erected in a soft ground. The surrounding place of the building at the outside of the earth retaining wall 2 is excavated with a slope keeping a slant angle corresponding to the ground. Then a solidifying agent is injected in the ground inside the earth retaining wall 2 to mix the soil of the ground with the agent and form a stabilized body 6. In this time, discharged slime is filled back into a space excavated in advance at the outer periphery of the earth retaining wall to form a solidified slime body 8 at the outer periphery of the earth retaining wall. And further, after a stabilized part 9 of the ground, extending deeper than the excavation depth under the solidified slime body 8 has been constructed, the inside of earth retaining wall is cut to the excavation bottom depth to construct a building foundation. In this way, a large scale temporary earth retaining wall is not required and hence, efficient excavation for foundation ground and construction of foundation can be realized.

摘要： PROBLEM TO BE SOLVED: To provide a vibration restraining device capable of suppressing increase of vibration in a horizontal direction of a suspended object by a simple configuration. SOLUTION: A suspension length of the suspended object 2 is changed by a winder 5, and a natural period of a vibration system 4 composed of a suspension material 3 and the suspended object 2 is changed. Accordingly, even if the natural period of the vibration system 4 exists in a natural period vicinity of a structure or the ground and there is a possibility of vibration increased by resonance, the resonance can be avoided just by changing the suspension length by the winder 5. By this, even without additionally providing a special vibration damping device, the increase of vibration in the horizontal direction of the suspended object is suppressed by a simple composition.

摘要： PROBLEM TO BE SOLVED: To provide an attenuating function with bringing-out of a certain frictional force on a sliding face, by using several sliding bearings in which the sliding face is treated with a preventive processing against sticking by use or a metallic plate and several laminated rubber bearings together. SOLUTION: Shoes 1' for a structure are provided at the bottom of the structure 1 and a durable metallic plate 5 is attached thereto. The sliding bearing 4 having a frictional force is put on a durable metallic plate 6 fitted to a foundation 2 through a specially processed part 7. Even if it is left in this condition for a long period, it is neither adheres nor the characteristics deteriorate and the attenuation property is kept. And further, when the sliding bearing 4 and the laminated rubber bearing 3 are used together, the proper vibration period of the base isolation system of the structure becomes longer in comparison with a single kind of the laminated rubber bearing 3. In this way, this system is sufficiently applicable for a structure having a long proper vibration period or an earthquake with a long periodical component, and hence this system can bring out an excellent vibration isolation effect.

摘要： PURPOSE:To resist vertical earthquake vibration so as to enable the solution of problems such as the low frequency, fluctuating load, vertical acceleration distribution of plane unevenness, horizontal shearing force and walking sensation of a floor in the large floor frame structure. CONSTITUTION:At the time of an earthquake, horizontal vibration generated to the floor of a large frame is surpassed by vertical vibration. In order to buffer and reduce this vertical vibration, a spring member 5 constrained in the horizontal direction, that is, provided with shear receiving material, is therefore used, and a level sensor 6 and a damper 7 are provided to form an earthquake resistant floor device 1. The vertical vibration can be thereby controlled by the spring members 5 so as to enable the solution of problems such as low frequency, fluctuating load, vertical acceleration distribution of plane unevenness, horizontal shearing force and walking sensation in the large floor frame structure.
