Description of the invention (,) [Technical field to which the invention belongs] The present invention, for example, relates to the propagation of vibrations to the surrounding ground surface of foundation structures such as presses or railway structures, and the propagation of vibration This is a consolidation site that suppresses the vibration of structures such as buildings installed on foundation structures and prevents the site from liquefying. [Previous Technology] In recent years, many vibration obstacles caused by machine map vibrations or traffic vibrations around the structure have occurred, and there are powerful measures to prevent vibration obstacles. In particular, when the base of a tartar on a weak ground is transmitted, the vibration spreads into the weak layer, which affects the surrounding ground surface distance, and the excellent vibration of the surface ground is sometimes induced. Furthermore, liquefaction of the weak ground due to earthquakes or other vibrations may cause great damage to structures, and measures to prevent liquefaction are also desired. As a method to prevent vibration obstacles, trenches may be provided around the foundation structure where vibration occurs. However, in this method, it is actually impossible to maintain a complete trench. Although it is necessary to set a retaining fence or support retaining grooves, the earth retaining fence will not only reduce the vibration efficiency, but also the lack of use of the land in the trench. . There is also a method for placing a vertical wall in a highly rigid ground around a foundation structure where vibration occurs. However, this method requires countermeasures against buried objects in water pipes and other places, or the lack of increased costs. In order to understand the deficiencies of the above-mentioned previous methods, the applicant first applied for an invention patent under the name of the invention "the vibration control method by burying a flat plate" (Japanese Patent Application No. 5-1 7 2 3 6 3) and obtained the Huai (Invention No. 2 8 5 G 1 8 7). The special feature is that this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page) --------- Order ---- -Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed 490531 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed A7 B7 V. Description of the invention (>) "In the place under the basic structure that vibrates or receives vibration, In the surrounding area of a foundation structure, a method of damping a flat plate with a higher rigidity than the surrounding site in the horizontal direction "The flat plate has a width equal to or greater than the width of the foundation of the basic structure; the width of the flat plate is 1/5 Thickness above left and right; and clipping speed set to a depth of α · Vs / 4f (but α = 0.5 to 0.8, Vs is the clipping speed of the site, and f is the number of vibrations) at a rigidity of 3 to 5 times the surrounding site. ". The above method is based on the analysis results or test results, and it is found that the flat plate has a higher vibration effect than the vertical wall. However, in the above method, when the high-pressure jet mixing engineering method is adopted, the upper part of the covered soil will be disordered by the injection pressure. When the mechanical stirring engineering method is used, the upper part will be disordered due to stirring from the ground surface. Either method will produce the covering soil. Part of the chaos. As a result, there have been defects such as occurrence of ground subsidence, difficulty in securing traffic ability, and poor workability. In addition, when the flat block is provided only for one stage, particularly in the case of a weak layer, the effect of suppressing the vibration of the lower layer portion is small, that is, the vibration of the lower layer portion becomes large, which may cause liquefaction. In order to understand the above-mentioned deficiencies, the applicant has applied for an invention patent under the name of the invention "consolidation site engineering method for damping and preventing liquefaction" (Japanese Patent Application No. 6-23 0 8 02) and has been granted a patent (Invention No. 2764696) This invention is characterized in that "consolidation sites in or below the foundation structure that emits or receives vibrations in or around the foundation structure cause a consolidation site with a higher strength than the surrounding sites, so that the upper part of the consolidation site is covered with soil To improve with lower strength than consolidated sites.

Description of the invention (々) According to this consolidation engineering method, the improvement of the covering soil part with low strength will not damage the damping effect, It can be sought to prevent ground surface settlement while ensuring accessibility, reducing costs and shortening the construction period. However, the above-mentioned consolidation engineering method is as small as possible to improve the volume ratio, and each consolidation body constituting the consolidation site is caused by, for example, columnar consolidation bodies that are spaced apart from each other without contacting each other. Therefore, when the site vibration is applied, each column shape The consolidated bodies vibrate individually. Therefore, although it will be a high cost, compared with a completely continuous flat block with an improvement rate of 100¾, not only the vibration damping effect is poor, but the weak support of the site may cause unequal settlement. Therefore, in accordance with the original state of improving the small volume ratio, when the site is vibrated, the columnar consolidation bodies are prevented from vibrating individually, and the support force of the site is increased to prevent unequal settlement of structures or sites. Apply for an invention patent under the name "Consolidation Engineering Method for Construction Sites for Damping and Preventing Liquefaction" (Japanese Patent Application No. 10- 1 0Q 〇 2 6). It is characterized by the pseudo- "consolidation of the site under the foundation structure that is vibrating or subject to vibration, or in the surrounding area of the foundation structure, or inside the foundation structure, resulting in a consolidation site with a higher strength than the surrounding site. In the method, each column-shaped consolidation body constituting the consolidation site is pseudo-connected to adjacent consolidation bodies and continuous with each other. " [Problems to be Solved by the Invention] However, in the "Concrete Control Method by Buried Slab Block" and "Consolidation Engineering Method for Vibration Control and Liquefaction Prevention of Construction Sites", there are low The lack of low damping effect. Therefore, for artificial vibration sources such as earthquakes and traffic vibrations, the range of the low vibration frequency is excellent -5-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the note on the back first (Please fill in this page again for matters) Order --------- Line: Printed by the Consumers 'Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 490531 Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Invention Description U) Sites, etc. There is a lack of vibration damping effect. The problem to be solved by the present invention is to utilize the advantages of the "consolidation engineering method of the site for damping and preventing liquefaction", and obtain a damping effect for vibrations in a low vibration frequency range below 5 Hz. [Means for Solving the Problems] The features of the present invention will be described with reference to FIGS. 1 and 2. The site consolidation engineering method of the consolidation site 1 in the land below the foundation structure, or around the foundation structure, or inside the foundation structure that causes vibration or vibration, constitutes a consolidation site 1 of higher strength than the surrounding sites. The columnar consolidation body 2 of the consolidation site 1 is continuous with the X-shaped connection of adjacent consolidation bodies, with λ being the Rayleigh wavelength, and d 1 being the interval between the lower ends of the consolidation bodies arranged coaxially next to each other. The interval between the upper ends of the consolidated bodies crossing d2, the range of improvement of the wave propagation direction: the distance from Wg (l / 2) A or W2 from the ground surface to the supporting layer. Interval of wave propagation direction of consolidated body: dl S (1/2) and d2 $ (1/4) λ ° Improved depth direction range: Hg (1/2 ~ 1/3) λ, or To supporters. The consolidation site 1 is formed according to the site improvement of the mechanical stirring engineering method or the high pressure spray stirring engineering method, and the chemical liquid injection engineering method can also be formed. The so-called high strength refers to a consolidation strength of 10 kgf / cm2 or more, and the Xiao speed is more than 3 to 5 times of the surrounding site. It is also called low strength, which means that the consolidation strength is less than 10 kgf / cm2, which is the same as the strength of the surrounding site. The evaluation method of the site vibration during an earthquake is a hypothetical input dynamic of the base plate.

Description of the invention (^) Although the vibration source of the pile foundation structure is supposed to be transmitted from the base plate, the vibration of the site has Strong reflection of surface area zoom characteristics. The present invention is an arrangement in which the consolidation bodies are X-shaped, and horizontal ground vibrations are suppressed by the consolidation body axial resistance. Alas, when the consolidation body is arranged in an X shape in this way, horizontal displacement occurs in the horizontal direction when the ground vibration occurs, so the axial direction acts on the compression force in one direction, such as the consolidation body that descends left and right, and the other direction, such as the left The falling consolidated body acts as a pull. Then, its displacement is repeated backward and forward movement, so each consolidation body alternately applies compressive and tensile forces. Therefore, it is better to ensure the rigidity of resistance to either compressive force or tensile force. As shown in FIG. 3, a high-rigid core material 2 'such as a steel rod is provided on the consolidation body 2 to stabilize the consolidation body itself. The rigidity is responsible for the compressive force, and the core material is responsible for the tensile force. [Embodiment of the invention] Fig. 4 shows the viaduct foundation 3 supported by the concrete pile 4 of the support layer 5 and shows the implementation of the present invention. The horizontal load width A is 12.00m, the depth B from the bottom of the viaduct foundation 3 (GL) is 2.50m, and the length of the concrete pile 4 is 14.5m. Alas, the concrete pile 4 is 100 mm thick, and 16 pieces are used in the illustration. The consolidation site 1 is caused by mechanical agitation on the ground, and adjacent pillar-shaped consolidation bodies cross in an X shape to be connected continuously. The diameter of this consolidation body 2 was 700 mm. Before the consolidation body was hardened, a steel rod with a diameter of 32 mm was used as a core material to be inserted into the center to fix the consolidation body. Alas, instead of mechanical mixing works, wooden piles or ready-made concrete piles can also be used.

Description of the Invention (b) Wave. The improvement range of the moving direction of mining is W 35.0 0 m, the interval of the wave propagation direction of the consolidation body, d 1 (the interval between the lower ends of the adjacent consolidated bodies arranged in the same direction) is 7.00 m, and d2 (the interval between the upper ends of the crossed consolidated bodies) is 4.00 m. In addition, the range of the improved depth direction Η is 9.00 m °, and then the setting angle of the consolidation body 2, that is, the setting angle θ 1 of the wave propagation direction of the consolidation body 2 is 45 °. Alas, in the example shown in the figure, when a part of the ground and a deep source of vibration (pile foundation, etc.) is targeted, from the lower end of the concrete pile 4, in the center of the consolidation site 1 where the wave propagation direction is improved (W / 2 = 1 7.50m) line, the angle Θ 2 formed with the horizontal line is the same angle 4 5 °. In addition, for a ground surface that is not shown in the figure, a vibration source or an earthquake is 45 °. Figure 4 targets a low vibration frequency band of 2.5 Hz, and a consolidation site is formed at λ = 60m. However, this combination also uses a consolidation site with a high vibration frequency band in the same site to correspond to a wide range of The vibration frequency band of the range is also possible. Next, the vibration damping effect in the example of the figure is shown in FIGS. 5 to 7. Alas, the imaginary line is shown in Fig. 4. For comparison, the buried flat block 6 is provided (refer to the above-mentioned invention • No. 2 850 0 1 8 7). The slab 6 is from the ground with a depth of 1.5m, a length of 22.0m, and a thickness of 2.0m. Figures 5 and 6 show the horizontal displacement responders by the horizontal load. They show that when the solid line is improved without the site, when the chain line is a flat plate, and when the one-point chain line is X-shaped. Fig. 5 shows that when the plate number is set at the vibration frequency f = 2.5 Hz, almost the same as when the consolidation site is not improved, is that the vibration damping effect cannot be obtained. However, when the connected consolidated body is X-shaped, the vibration damping effect is remarkable. -8-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) I ^ --- · '--- K -------- K ---- Order --- ----- Line (Please read the notes on the back before filling this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 490531 A7 B7 V. Description of the invention (7) Figure 6 shows the number of vibrations f 2.0 5.0 H z Time. In this case, although the vibration damping effect is still obtained with the distance of the plate from the vibration source to about 15 m ', the vibration damping effect is obtained up to 20 m or more when the connected consolidated body is X-shaped. Fig. 7 shows the reduction rate of the ground surface amplitude when the core material is inserted into the consolidated body. In the figure, thick solid lines a and thin solid lines b indicate a core material, and thick chain lines c and fine chain lines d indicate a coreless material. The thick solid line a and the fine chain line c indicate that d 1 is 5.0 0 m, and the thin solid line b and the fine chain line d indicate that d 1 is 7.00 m. The effect of the core material having a large reduction ratio 'core material is obvious. [Effects of the invention] High suppression effect in low vibration frequency bands' also has a high effect on vibration transmission from the middle and deep parts of the ground, so it is not only a vibration source for ground surface, measures for liquefaction such as earthquakes, or pile foundation structures The application of a vibration source as a vibration source can be expanded. Roughly causing the consolidation body 'short construction period' cheap public expenses. When constructing a structure above the improvement area, it can prevent the increase of support force on the site or unequal settlement. In the same site, a combination of consolidation sites from the low vibration frequency band to the high vibration frequency band is used to obtain a vibration suppression effect in a wide vibration frequency band.
