Description

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 483973 A7 __ B7 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an injection pipe device and a site formed by bundling a plurality of independent thin pipes together. Injection method; in particular, an injection pipe device and site injection method. For a site where the status of each layer of the site is different, not only can the most appropriate injection be performed simultaneously for each layer, but also the longitudinal and transverse directions in the site can be simultaneously and simultaneously. Three-dimensional injection; and can be injected from a large cylindrical or cylindrical infiltration source. Therefore, a large amount of injection liquid can be infiltrated between soil particles and consolidated under a low pressure. As a result, the injection effect is excellent. And can shorten the injection period. [Conventional technology] As the water permeability coefficient or clearance ratio of each layer of the construction site is usually different, the condition of the construction site of each layer is different. Therefore, in the past, a double pipe rod injection method of alternately injecting fast-drying cement slurry and slow-drying cement slurry while moving the injection level up 3 3 C m or 50 cm, or a single injection of cement series After the material is injected, a double-pipe double plugger method for injecting a solution-type secondary injection material is used. Furthermore, when a chemical solution is to be injected into a construction site, although it is not shown in the past, an injection pipe such as a double pipe having a plurality of discharge ports at different positions in the axial direction is used. After the pipe is buried in the site, the injection material is introduced into the injection pipe from the upper end of the injection pipe, and then the introduction material is simultaneously injected into the site from the plurality of outlets. Furthermore, after the injection pipe is buried in a hole obtained by drilling in the site, a sleeve cement slurry or a quick-drying cement slurry is filled between the hole wall and the injection pipe. The Chinese paper standard (CNS) A4 is applied to this paper.

Description of the invention (2) 'The same as above, the injection material is injected into the site through the outlet of these injection pipes'. [What the invention wants to solve Subject] The conventional injection method described above will be described with reference to Figs. 19 to 21. Fig. 19 is an explanatory diagram of a double pipe rod injection method or a rod injection method; 0 The injection liquid sent to the site 7 basically starts from a spherical infiltration source 21 corresponding to the diameter r ◦ of the injection pipe rod 20 and penetrates spherically. The symbol 2 2 is a spherical infiltration solid. Nodule 0 The above-mentioned infiltration source 2 1 has a diameter of Γ 〇 and is quite small, so it is difficult to economically spit out a speed of 1 0 to 2 0 ( Liters / minute), infiltration of soil particles, easy to become vein-like (distributed like blood vessels) injection. Moreover, even if the quick-drying cement slurry is injected first, the cement slurry will flow in a vein, and the subsequent setting time is long. The injection liquid still easily flows along the vein-like solidified body. More seriously, the injection liquid will emerge from the surrounding of the injection tube as shown by the arrow. Figure 20 shows other injection methods using the injection tube. After inserting the injection pipe rod 20 of Fig. 19 into a certain depth in the construction site 7, pull up a certain length to form a cylindrical infiltration source 21. This infiltration source 21 is a cylindrical space. The injection liquid starts to be injected from this space. In this case, as in Fig. 19, the injection liquid will pop out around the injection pipe stem as shown by the arrow, and it is difficult to penetrate to a certain depth. Fig. 21 is a double tube Illustrative diagram of the double plugging method. This method is based on the Chinese paper standard (CNS) A4 (210 X 297 mm). 尺度 ϋ ϋ .1 · ϋ ϋ 1 ϋ ϋ ϋ 1 · ϋ > ϋ ^ 1 ϋ _1 ϋ 1 1 ϋ 1 ϋ ϋ · ϋ ^ 1 I (Please read the back first Please fill in this page again for precautions) 483973 A7 _ B7 V. Description of the invention (3) Γ Please read the precautions on the back before filling in this page) Between the outer tube 1 2 and the hole wall 9, that is, in the injection hole 8, Fill the self-stomach cement slurry 2 3, cover the outer tube 1 2 with the sleeve cement slurry 2 3 to prevent the main λ liquid from rising upward; this construction method breaks the sleeve cement slurry 2 3, and from ί 求 & Infiltration source r. Injection, this point is the same as the method of FIG. 19. It is difficult to achieve these χ & improvements with continuous large-capacity injection for liquefaction prevention projects and the like. In an ordinary injection process, the interval between injection holes is about 1.0 m. In contrast, in the liquefaction prevention project, considering economical efficiency, it must be between 1.5 m and 4 m. For example, in the case of a square arrangement with an injection hole interval of 2 m: a buried arrangement of the injection pipe P = 2m X 2m square arrangement injection speed f = 20 (l / min) improved flat area of each injection pipe Ap = 2mX2m = 4m2 Improved soil volume at each level (m3) V = 2 m (improved thickness of each level) X 4m2 = 8m3 Injection volume at each level (K1) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Q = Vx (0.35 ~ 0.40) = 2.8m3 ~ 3.2m3, with an average of about 3.0m3 (35 ~ 0.40 penetration rate) The injection time for each level t1 = 3kl + 0.02kl / min = 150min = 2.5 hours (injection duration) must be The injection is performed for a long time. In the case of a square configuration where the injection hole spacing is 4 m, Ap = 4mX 4m = 16m2. This paper size applies the Chinese National Standard (CNS) A4 specification (210 x 297 mm). System 483973 A7 --- B7 V. Description of the invention (4) ~ Improved soil volume of the level V = 2m (improved thickness) X 16m2 = 32m 'Injection volume of one level (kl) Q = Vx (0.35 ~ 0.40) = 32 x (0.35 ~ 0.40) = 1 1.2 ~ 12.8kl and 12kl (average) Right injection speed f = 20 (1 / min), then the injection time of each level is t = 12kl + 0.02kl = 600min = 10 hours. Therefore, the effective penetration source must be made larger. If the effective infiltration source is made larger, even if the injection is performed at a large discharge amount, the injection rate per unit surface area of the infiltration source is reduced, and clogging does not occur due to solidification. Therefore, a large amount of injection solution can be injected at a low pressure. Continuously inject while consolidating a wide range of sites. In order to solve this problem, the applicant developed the technology disclosed in Japanese Patent Application Laid-Open No. 7-3 0 0 8 4 9 and obtained the Japanese Patent No. 2 8 5 2 7 2 1. This previous patent is to bundle a plurality of thin tubes for medicinal solution, insert them into the holes obtained by drilling in the site, and then fill the sealing cement slurry between the thin tube and the hole wall. After the sealing cement slurry is cured, , Inject the medicinal solution from each thin tube. As a result, the outlets of the thin tubes are located at different positions in the axial direction, and can be simultaneously injected into the site in the vertical and horizontal directions in three dimensions. This has the advantages of shortening the construction period, improving the construction accuracy, and allowing the construction to proceed as designed. However, in this previous patent, when the size of the paper to be ejected is different from the axial direction, the Chinese National Standard (CNS) A4 (210 X 297 mm) is applicable.

Description of the invention (5) When the outlets are injected at the same time, the sealing cement slurry in contact with the respective outlets is destroyed, as if the stitches sewed by the sewing machine were stretched to the left and right sides and broken along the pins in a straight line. It is broken continuously and cannot function as a seal. Therefore, avoid injecting from all the ejection outlets at once and injecting the ejection outlets that do not inject into the part to prevent continuous breakage.

For sites with different site conditions on each floor, not only can the most appropriate injection be achieved at the same time, but also It can be injected three-dimensionally into the horizontal and vertical directions of the construction site at the same time, which can shorten the construction period. Furthermore, the entire perforation hole wall of each level can be infiltrated to make the effective source of infiltration larger, and the injection can be performed under low pressure. In all levels, the medicinal solution can be injected as designed; further, large-capacity soil can be continuously injected for a long period of time for the liquefaction prevention process.

Invention Description (12) As the above-mentioned hole sealer 3, although it can be used: air or Inert gases such as nitrogen, or fluids such as liquids and hardening liquids, are filled into the bag body, and the plugging device is formed by expanding the plugging device, hard plugging device, or elastic plugging device; Ideally, as shown in FIG. 1, a plugging device formed by passing any of the narrow tubes of the bundle injection tube 2 through a bag body and pressing the cement slurry to expand the same is used. The material of the plugging device can be cloth, rubber, synthetic resin, or the like. In addition, if the fluid filled in the plugging device is air or liquid, it is easy to remove the bundle injection pipe from the ground after the completion of the injection. Then, just fill the cement slurry and let it solidify. The injection tube device 1 of the above structure is inserted into the injection hole 8 drilled in the site 7, and then the hardening liquid such as cement slurry is filled into the bag body through the thin tube 5 and expanded to form the plugging device 3, 3. ..... 3. At this time, in the injection hole 8, an independent space 10 is formed between the adjacent pair of plugging devices 3, 3 and the hole wall 9. After the hardening liquid is hardened, the injection liquid is discharged from the discharge port 4 so that the injection liquid passes through the entire hole wall 9 of the space 10 and is infiltrated and injected into the ground plate 7 in a cylindrical shape, thereby forming a cylindrical infiltration consolidation in the ground plate 7 Body 1 1. In addition, by simultaneously injecting the injection liquid from the plurality of discharge ports 4, 4,... 4, a stack of columnar impregnated consolidation bodies 11 is simultaneously formed. In particular, in the present invention, the cylindrical impregnation from the space 10 is performed simultaneously in a plurality of layers, and a layer of the cylindrical impregnated consolidation body 11 can be formed in one breath. For example, in the present invention, the bore diameter of the injection hole 8 is 10 cm, and the length of the plugging device 3 is lm, and the plugging device 3 is counted from the center of the plugging device 3 in the axial direction of the thin tube 5 every 2 m configuration.

Description of the invention (13) In this case, 1 injection level is 2 m, and the size of the cylindrical infiltration source for each level is the diameter A cylindrical shape with a length of 10 cm and a length of lm. In contrast, for a spherical infiltration source, the surface area is a ball with a diameter of 10 cm. Therefore, as in the case of the liquefaction prevention process, it is necessary to continuously inject the injection liquid in a large amount for a long time. In the present invention, it is possible to permeate continuously for a long time with a large discharge amount under a low pressure without blocking. Furthermore, in the space 10, as shown in FIG. 16 described later, the sleeve cement slurry can be filled, and then the sleeve cement slurry is broken, and the injection liquid is injected into the floor from the discharge port. This application method is suitable when the floor is deposited in layers and has slightly different water permeability. In this case, the plugging device separates the sleeve, so even if the sleeve cement slurry is injected from all the injection ports simultaneously, the sleeve cement will not break like the stitches of the sewing machine from the ground to the ground. For the conventional method of making the above-mentioned permeation levels at each level while pulling up, the injection liquid will not only overflow from the surrounding of the injection pipe to the ground, but also easily move to the direction of the thin ground surface, and it is difficult to level each level Drenched. However, according to the present invention, if a plurality of upper and lower layers are simultaneously immersed in a cylindrical shape, the flow between the upper layer and the lower layer of the injection liquid is mutually restricted due to the permeation pressure between each other. It is restricted to be infiltrated into a columnar shape in the horizontal direction, and a stacked layer of the infiltrated consolidated body 1 1 is surely formed. Furthermore, in the present invention, since each level is separated by the plugging device 3, 3, it is possible to select the setting time, injection speed, and injection volume according to the status of the soil layer of each level, and inject the injection liquid into the ---- — — — — — — — — — — · 1111111 — — — — — — — — (Please read the notes on the back before filling out this page) This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297) (Mm) -16- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 483973 A7 __ B7 V. Description of the Invention (M) When applying the present invention, in the case of improving a shallower site, use the device shown in Figure 6 . Fig. 6 is a sectional view of another specific example of the injection pipe device of the present invention and an explanatory diagram of a site injection method using the injection pipe device. In FIG. 6, reference numeral 1 is an injection pipe device 1, which is composed of a bundle injection pipe 2 and at least one sealer 3 arranged around the bundle injection pipe; the bundle injection pipe 2 and the first The figure is the same. The plurality of thin tubes 5, 5 ... 5 are used so that the respective outlets 4, 4 ... 4 are spaced a certain distance from each other in the axial direction, and an adhesive or sponge glue is used. It is formed by fixing on the pedestal and then bundling it with a strap. The above-mentioned injection pipe device 1 is inserted into an injection hole 8 drilled in the ground 7. The plugging device 3 is formed by inserting the cement slurry into a bag body (not shown) through an arbitrary thin tube 5 after being inserted into the construction site 7 to expand and solidify it. At this time, there is at least one discharge port 4 below the plugging device 3, and in FIG. 6, there are a plurality of discharge ports 4, 4 ... 4. Furthermore, in the injection hole 8, a space 10 is formed between the plugging device 3 and the hole wall 9, and the entire hole wall 9 of this space 10 is passed through the outlet ports 4, 4, ... 4 The discharged injection liquid permeates into the ground plate 7 to form a cylindrical infiltrated consolidation body 1 1 Furthermore, the injection pipe device 1 of FIG. 6 is inserted into the injection hole 8 drilled in the ground plate 7 and After the sleeve cement slurry is injected into the injection hole 8, the fluid is filled into the bag body and expanded to form the plugging device 3. By this means, a sleeve (not shown) is formed between the plugging device 3 and the hole wall. Then, the injection liquid is discharged from the discharge port 4 to break the sleeve cement slurry so that the Chinese paper standard (CNS) A4 specification (210 X 297 male "17_II ------") -—— -Name！ 1 Order！ ----- (Please read the notes on the back before filling out this page) Printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs 483973 A7 ---- B7 V. Invention Explanation (15) The injection liquid discharged from the discharge port 4 is injected into the construction site 7. In this case, the sleeve cement slurry can be injected during the insertion of the injection pipe device 1 The “performation may be performed after insertion.” Also, instead of the bundle injection tube 2 shown in FIG. 1 and FIG. 6, a plugging hole having a plurality of thin tubes 5, 5, ... 5 may be used. The injection tube of the injection tube for the device is an injection tube having a discharge port at a position where the injection tube is located inside the bag sealing device. This is, for example, a bundle injection tube shown below in FIG. 10 below, that is, Has: an injection tube for a plugging device, and a plurality of thin tubes arranged along the outer wall of the injection tube for a plugging device; and at least a position of the injection tube for a plugging device in a bag hole sealing device, which has a discharge port Bundle injection tubes. In this case, by filling the bag with fluid from the discharge port and expanding it to make a hole sealer, a thin tube is not required to expand the bag body, which can reduce the number of thin tubes. Furthermore, the hole sealer is injected with The tube can also function as a support rod for a thin tube. The details will be described later. In addition, even if the sleeve tube does not have a rubber sleeve, as long as the injection tube has a spout that opens at least in the bag body, the sleeve tube can Measurement before and after injection The permeability of the site confirms the injection effect. If the injection effect is insufficient, it can be re-injected. In addition, one injection of the suspension type cement slurry can be performed in advance to homogenize the site; it can also be performed by sleeve injection and sleeve cement slurry. It is injected between the bundle thin tube and the pores. In the example in Fig. 6, since there is no sealer 3 at the lowermost part of the bundle injection tube 2, the shape of the permeated consolidation body 1 1 tends to a semi-elliptical shape.
