Description of the invention: [Technical field to which the invention pertains] The present invention relates to an expansion grouting plug for use as a filling pipe for a locking bolt and a pouring material in a natural foundation reinforcing project such as tunnel engineering, and the use of the bolt Grouting method. [Prior Art] It is known to cut a hole in a normal surface of a natural hole by a hole punching machine, insert a pipe into the hole, and pour the hardened grouting material such as cement slurry, and then insert the steel bolt type locking bolt. In the hole, the locking bolt is fixed by hardening of the hardened grouting material, and the reinforcing plate is protruded to the bolt portion of the external locking bolt through the self-shaving hole, and the nut is tightened to reinforce (for example, refer to the patent Publication 2 0 0 0 - 3 0 3 4 8 0). Further, as a lock bolt that can be fixed without using a curable grout material, it is known that a front end portion is locked, a tubular shape having a supply port at the rear end portion, and an expansion portion that is radially expandable by application of an internal pressure is provided in the intermediate portion. The expansion snail of the section (for example, refer to Japanese Patent Publication No. 5 20 0 of 1990). The expanded bolt structure is formed by applying an internal pressure after inserting the hole and expanding the portion of the expansion portion which pushes a part of the plastically deformable tube into the inner side in the radial direction to adhere to the ground. However, in the case of a steel bolt type locking bolt fixed by a hardened grouting material, there is a secondary problem. In order to strengthen the hardened grouting material in the foundation around the hole, the sealing pipe and the opening of the hole are sealed tightly, and the hardening slurry is supplied under high pressure, so that the hardening grouting material fully penetrates the surrounding foundation, however , not 312XP / invention manual (supplement) /94-05/94102434 and other screw-in system f has been swelled in the shape of the bulging expansion only 5 1335377 into the hard and easy to fill the» base system is still pressed by the expansion 5 Irrigation 6 This seal is difficult to perform and must be sealed when the filling tube is inserted. The sealing is released when the filling tube is pulled out, and the workability is poor. Especially in the case of water rushing, even if it is difficult to pour into the hardened grouting material, the chemical grouting material will still flow out during the period before hardening, and it is difficult to fix the locking bolt. Further, during the period before the hardening of the grouting material is hardened, the deformation of the natural foundation is likely to occur, and the loosening range of the natural foundation is enlarged. On the other hand, in the case of the expansion bolt, since it can be fixed without using the hardenable pulp, there is an advantage that the above problem does not occur.
然而，於該膨脹螺栓情況下，在周圍地基脆弱時，有 使將膨脹部膨脹，固定力仍不充分，補強效果容易不彰 問題。其雖可如同鋼製螺栓型鎖緊螺栓，藉由使用灌入管 將硬化性灌漿材灌入削孔，使硬化性灌漿材滲透周圍地 予以強化來解決，不過，若是如此，即會發生與上述鋼 螺栓型鎖緊螺栓相同的問題。 本發明係有鑑於上述習知問題而開發者，其目的在於 舊保有膨脹螺栓的優點，並且容易謀得利用硬化性灌漿 的灌入對周圍地基的強化。 【發明内容】 為達到上述目的，本發明提供形成可自後端部施加内 的管狀，具有藉由施加内壓徑向膨脹的膨脹部，以及藉 施加内壓使灌入口開口的灌入口形成部的膨脹灌漿螺栓 本發明之膨脹灌漿螺栓可藉由施加内壓使膨脹部 脹，密貼地基，並可於灌入口形成部使灌入口開口。而且 在對該地基的密貼及灌入口的開口後，可藉由自本膨脹 312XP/發明說明書(補件)/94-05/94丨02434 1335377 漿螺栓的後端部灌入硬化性灌漿材，經由上述開口部 化性灌漿材灌入周圍地基。 由於如上述，本發明之膨脹灌漿螺栓的膨脹部膨脹 貼地基，密封膨脹灌漿螺栓與地基間，故即使在水湧 況下，仍可不待硬化性灌漿材的灌入硬化止水。並且 由上述密封，可防止硬化性灌漿材的洩漏，由於硬化 漿材的灌入作業性佳，同時，可藉由硬化性灌漿材的消 強化周圍地基，故即使對脆弱地基，仍獲得良好的固 又由於本發明之膨脹灌漿螺栓於硬化性灌漿材的 後，依舊留作鎖緊螺栓，故於硬化性灌漿材的灌入後 維持上述密封，即使於水湧出處，仍可防止硬化性灌 的流出。更由於本發明之膨脹灌漿螺栓即使於周圍地 弱情況下，若使膨脹部膨脹，密貼地基，仍可不待硬 灌漿材的灌入硬化，獲得儘管不充分，卻達到某種程 補強效果，故可抑制硬化性灌漿材硬化前的期間内的 地基鬆動。 本發明之膨脹灌漿螺栓之灌入口形成部大致分為， 藉内壓破碎的加壓套筒者、使用藉内壓分離的蓋及蓋 筒以及其他構造者。其詳細及優點說明於後。 又，本發明亦提供將上述本發明之膨脹灌漿螺栓插 基中，施加内壓於膨脹灌漿螺栓，在進行膨脹部的膨 灌入口的開口後，供給硬化性灌漿材於膨脹灌漿螺栓 由張開的灌入口灌注硬化性灌漿材於周圍的灌漿工法 312XP/發明說明書(補件)/94-〇5/941 〇2434 將硬 ，密 出情 ，藉 性灌 入， 定狀 灌入 ，仍 漿材 基脆 化性 度的 天然 使用 用套 入地 脹及 ，經 7 1335377 本發明之灌漿工法係活用上述本發明之膨脹灌漿螺拴 的特徵的工法，如上述，其可一面謀得水湧出的早期止水、 硬化性灌漿材的洩漏及流出的防止、硬化性灌漿材硬化前 期間内天然地基的鬆動抑制等，一面進行利用硬化性灌漿 材的灌入的地基強化工程。 又，本發明之灌漿工法的態樣及其他優點說明於後。 【實施方式】 以下，根據圖式說明本發明。However, in the case of the expansion bolt, when the surrounding foundation is weak, the expansion portion is inflated, the fixing force is still insufficient, and the reinforcing effect is not easily solved. Although it can be used as a steel bolt type locking bolt, the hardened grouting material is poured into the hole by using a pouring pipe, and the hardened grouting material is infiltrated into the surrounding area to be strengthened, but if so, it will occur as described above. The same problem with steel bolt type locking bolts. The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to maintain the advantages of an expansion bolt in the past, and it is easy to achieve reinforcement of a surrounding foundation by pouring of a hardenable grout. SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a tubular body formed to be applied from a rear end portion, an expansion portion radially expanded by application of an internal pressure, and an inlet portion forming portion of the inlet opening by applying an internal pressure. Expanded Grouting Bolt The expansion grouting bolt of the present invention can expand the expansion portion by applying internal pressure, adhere to the foundation, and can open the inlet opening at the inlet portion. Moreover, after the adhesion to the foundation and the opening of the filling inlet, the hardened grouting material can be poured into the rear end portion of the slurry bolt from the expansion 312XP/invention manual (supplement)/94-05/94丨02434 1335377. The surrounding ground is poured through the above-mentioned open-ended grouting material. As described above, the expansion portion of the expansion grouting bolt of the present invention is expanded to the ground and seals between the expansion grouting bolt and the foundation, so that even in the case of water surge, the hardening of the grouting material can be hardened and stopped. Further, by the above sealing, it is possible to prevent the leakage of the hardenable grouting material, and the hardening slurry is excellent in the filling workability, and at the same time, the surrounding foundation can be strengthened by the hardening of the grouting material, so that even for the fragile foundation, good results are obtained. Since the expansion grouting bolt of the present invention remains as a locking bolt after the hardening grouting material, the above sealing is maintained after the hardening grouting material is poured, and the hardening irrigation can be prevented even in the water gushing place. Outflow. Moreover, even if the expansion grouting bolt of the present invention is weakened in the surrounding environment, if the expansion portion is inflated and the foundation is adhered, the hard grouting material can be hardened without being filled, and although it is insufficient, it can achieve a certain process of reinforcing the effect. Therefore, it is possible to suppress the looseness of the foundation during the period before the hardening grouting material is hardened. The inlet forming portion of the expansion grouting bolt of the present invention is roughly classified into a pressurizing sleeve which is crushed by internal pressure, a cover and a cover which are separated by internal pressure, and other constructors. The details and advantages are explained later. Moreover, the present invention also provides the above-mentioned expansion grouting bolt inserting base of the present invention, applying an internal pressure to the expansion grouting bolt, and after opening the opening of the expansion irrigation inlet of the expansion portion, supplying the hardening grouting material to the expansion grouting bolt is opened Filling and pouring hardening grouting material in the surrounding grouting method 312XP / invention manual (supplement) /94-〇5/941 〇2434 will be hard, densely out, borrowed, filled, still pulp The natural use of the embrittlement degree of the base is used for the expansion of the ground. According to the method of the grouting method of the present invention, the above-mentioned method of using the expanded grouting screw of the present invention, as described above, can be used for the early stage of water gushing. The foundation strengthening work using the hardening grouting material is carried out while stopping the leakage of the hardened grouting material and the prevention of the outflow, and the suppression of the loosening of the natural foundation during the hardening of the hardened grouting material. Further, aspects of the grouting method of the present invention and other advantages will be described later. [Embodiment] Hereinafter, the present invention will be described based on the drawings.

And 4B is an enlarged cross-sectional view and an enlarged front view of the front end portion of the expansion grouting bolt shown in Fig. 1. As shown in Figs. 1 to 3, the expansion grouting bolt 1 A of this example is formed with an inlet sleeve 2 provided at the rear end portion. A mouthpiece and a tubular shape integrally connected to the expansion portion 3 in front of the inlet sleeve 2 constitute an internal pressure that can be applied via the inlet sleeve 2. The inlet sleeve 2 is formed into a circular tube which does not substantially expand in diameter even under internal pressure, and communicates with the space in the expansion portion 3, and is axially opened. Further, the inlet sleeve 2 is formed with a screw portion 5 on the inner circumferential surface thereof, and is welded to the expansion portion 3 via the weld ridge welding 4. The threaded portion 5 is connected to an apparatus for supplying the internal pressure and the supply of the hard grouting material, which will be described later, and the operation of forming the inlet 7 (see 圊8 A and 8 C) by the boring tool 6 (see Fig. 10). Although the screw portion 5 of the illustrated example is formed on the inner circumferential surface of the inlet sleeve 2, it may be formed on the outer circumferential surface. As can be seen from the section of Fig. 1, the expansion portion 3 is axially inwardly depressed 8 312XP / part of the invention (supplement) / 94-05 / 94 丨 02434 1335377 a circular tube with an indentation for setting a bending depression The cross section of the portion 8 has a substantially C-shaped configuration. The expansion portion 3 can push the indentation portion 8 to the outside and radially expand by applying an internal pressure.
膨脹灌漿螺栓1 A的膨脹部 3由可進行上述膨脹，亦可 在解除内壓後，維持該膨脹形狀的可塑性變形材料構成。 具體而言，雖可使用鐵、銅、鋁或其合金等金屬，不過， 一般為了於強度上優異，以由鋼管構成較佳。又，按用途， 亦可由橡膠或合成樹脂等可撓性材料或使用其作為基材的 材料構成。 本例之膨脹部3自上述入口套筒2附近連接至前端，膨 脹部3的前端部分構成灌入口形成部9A。灌入口形成部9A 係藉内壓形成用來將後述硬化性灌漿材灌入地基的灌入口 7 (參照圖8 A及圖8 C )，本例之灌入口形成部9 A具備：可 破碎加壓套筒1 0，其填隙安裝於膨脹部3的前端部；脆化 部（於圖式上與其他部分並無區別），其形成於該加壓套筒 1 0填隙安裝區域的膨脹部3 ;以及熔接部1 1 (參照圖3及 圖4 A、圖4 B )，其閉塞膨脹部3的前端開口部。 於填隙安裝在膨脹部 3 前端部的加壓套筒 1 0的兩端 緣，在形成於膨脹部3的壓陷部8的壓陷口（大致呈C字形 形狀的不連續部）上的對應位置，形成開縫1 2。該開縫1 2 雖非必要，但最好將其設置，俾易於調整後述加壓套筒1 0 的破碎壓力。加壓套筒1 0雖可由與構成膨脹部3的材料相 同的材料構成，不過，為調整後述破碎壓力，亦可由不同 的材料構成。 9 312XP/發明說明書(補件)/94-05/94102434 1335377 特別是如圖4A及圊4B所示，膨脹部3的前端開口部以 可抑制壓陷部8推出所造成的擴徑的熔接部1 1閉塞。該熔 接部1 1沿膨脹部3前端的大致C字形形狀，不連結壓陷部 8的壓陷口 ，跨在膨脹部3前端與加壓套筒1 0間，覆蓋膨 脹部 3的前端開口形成。因此，若施加内壓於膨脹部 3， 即如圖4B箭頭所示，施加使膨脹部3前端雖未擴徑，卻自 壓陷口向左右張開的力量，俾可經由上述開縫1 2，使加壓 套筒1 0破碎。The expansion portion 3 of the expansion grouting bolt 1 A is formed of a plastically deformable material which can be expanded as described above and which maintains the expanded shape after the internal pressure is released. Specifically, although a metal such as iron, copper, aluminum or an alloy thereof can be used, it is generally preferably made of a steel pipe in order to be excellent in strength. Further, depending on the application, it may be composed of a flexible material such as rubber or synthetic resin or a material using the same as a substrate. The expansion portion 3 of this example is connected to the front end from the vicinity of the inlet sleeve 2, and the front end portion of the expansion portion 3 constitutes the irrigation inlet forming portion 9A. The filling port forming portion 9A is formed by the internal pressure to form a filling port 7 for pouring a hardening grouting material to be described later into the foundation (see Figs. 8A and 8C). The filling port forming portion 9A of this example is provided with a crushable addition. The pressure sleeve 10 is caulked to the front end portion of the expansion portion 3; the embrittlement portion (which is not different from other portions in the drawing) is formed in the expansion of the pressure-filled mounting region of the pressure sleeve 10 The portion 3 and the welded portion 1 1 (see FIGS. 3 and 4A and 4B) block the front end opening of the expansion portion 3. The both ends of the pressurizing sleeve 10 which is attached to the front end portion of the expansion portion 3 by caulking, are formed on the depression (a substantially C-shaped discontinuous portion) of the depression portion 8 formed in the expansion portion 3 Corresponding positions form a slit 1 2 . Although the slit 1 2 is not necessary, it is preferable to provide it, and it is easy to adjust the crushing pressure of the pressurizing sleeve 10 described later. The pressurizing sleeve 10 may be made of the same material as the material constituting the expansion portion 3, but may be made of a different material in order to adjust the crushing pressure described later. 9 312XP/Invention Manual (Supplement)/94-05/94102434 1335377 In particular, as shown in FIGS. 4A and 4B, the front end opening portion of the expansion portion 3 is a welded portion capable of suppressing the expansion of the indentation portion 8 1 1 blocked. The welded portion 1 1 has a substantially C-shape along the front end of the expansion portion 3, and is not connected to the depression of the indentation portion 8, and spans between the front end of the expansion portion 3 and the pressure sleeve 10, and covers the front end opening of the expansion portion 3. . Therefore, when the internal pressure is applied to the expansion portion 3, that is, as shown by the arrow in Fig. 4B, the front end of the expansion portion 3 is not expanded, but the force is released from the pressure depression to the left and right, and the sill can pass through the slit 1 2 The crushing sleeve 10 is broken.
上述加壓套筒1 0填隙安裝的膨脹部3前端部分的一部 分或全部構成物理上或化學上脆弱化的脆化部（於圖式上 與其他部分並無區別）。該脆化部係指可隨著上述加壓套筒 1 0的破碎而破裂，使灌入口 7 (參照圖8 A及圖8 C )開口， 容易破裂或斷裂的部分。 上述脆化部可藉由利用例如縮徑加工等加工硬化而脆 弱化、利用加熱或冷卻處理脆弱化、藉氫氣或乙炔氣脆弱 化、利用滲碳處理或酸或鹼處理脆弱化、其組合等形成。 例如，可藉由填隙安裝加壓套筒1 0，將該部分的膨脹部3 縮徑，形成加工硬化的脆化部。又，亦可藉形成熔接部1 1 時的熱形成脆化部。 於本例中，藉由在利用其形成時的加工硬化脆化的壓陷 部8的底部附近，填隙安裝加壓套筒1 0到膨脹部3縮徑為 止，並設置熔接部1 1，進一步加工硬化，形成脆化部。又 由於壓陷部 8的底部附近如後述，容易藉由加壓套筒 10 的破碎施加大的力量，故適宜作為形成脆化部的位置。 10 312XP/發明說明書(補件)/94-05/94102434 1335377 本例的膨脹灌漿螺栓1 A係於靠近膨脹部3的後端部及 靠近前端部的外周部捲繞密封材1 3所構成者。作為該密封 材1 3，除了橡膠、彈性體等彈性材料外，亦可使用織布、 不織布等布帛。雖然在密封材1 3係可隨著膨脹部3的膨脹 而變的彈性材料情況下，亦可密貼密封材 1 3於膨脹部 3 的外周面，不過，在使用布第等情況下，以可容許膨脹部 3的膨脹的程度鬆弛捲繞較佳。又，壓陷部8的凹入部亦 以可埋入較佳。A part or all of the front end portion of the expansion portion 3 to which the pressurizing sleeve 10 is caulked constitutes a physically or chemically weakened embrittlement portion (in the drawing, there is no difference from the other portions). The embrittled portion is a portion that can be broken by the breakage of the pressurizing sleeve 10, and the inlet 7 (see Figs. 8A and 8C) is opened, and is easily broken or broken. The embrittlement portion may be weakened by work hardening such as reduction processing, fragile by heating or cooling treatment, fragile by hydrogen gas or acetylene gas, vulcanization by carburizing treatment or acid or alkali treatment, combination thereof, etc. form. For example, the pressurizing sleeve 10 can be attached by caulking, and the expanded portion 3 of the portion can be reduced in diameter to form a work-hardened embrittled portion. Further, the embrittlement portion may be formed by the heat when the welded portion 1 1 is formed. In the present example, the pressurizing sleeve 10 is caulked to the vicinity of the bottom of the indentation portion 8 where the work hardening is formed by the formation thereof, and the welded portion 10 is fixed to the diameter of the expansion portion 3, and the welded portion 1 is provided. Further work hardening to form an embrittlement. Further, since the vicinity of the bottom of the indentation portion 8 is easily applied by the crushing of the pressurizing sleeve 10 as will be described later, it is suitable as a position for forming the embrittled portion. 10 312XP/Invention Manual (Supplement)/94-05/94102434 1335377 The expansion grouting bolt 1A of this example is formed by winding the sealing material 13 near the rear end portion of the expansion portion 3 and the outer peripheral portion near the front end portion. . As the sealing material 13, an elastic material such as a rubber or an elastomer may be used, and a fabric such as a woven fabric or a non-woven fabric may be used. In the case where the sealing material 13 is an elastic material which can be changed in accordance with the expansion of the inflation portion 3, the sealing member 13 may be adhered to the outer circumferential surface of the inflation portion 3, but in the case of using the cloth or the like, It is preferable that the degree of expansion of the expansion portion 3 is allowed to be loosely wound. Further, it is preferable that the concave portion of the depressed portion 8 is buried.
由於若設置上述密封材1 3，膨脹部3即隨著其膨脹，經 由密封材1 3，密貼地面，故可提高密封性，使硬化性灌漿 材的洩漏防止或水湧出的止水更為確實。於本例中，雖然 密封材13設於靠近後端部及靠近前端部二處，不過，亦可 僅為靠近後端部的密封材1 3，或設置密封材1 3於三處以 上。 且，本例之膨脹灌漿螺栓1 A的入口套筒2稍前方構成 一連串膨脹部3，不過，卻將圖示膨脹部3的後端部或前 端部作成亙適當長度的單純管材，偏靠前端部側或後端部 側設置膨脹部3，或者，亦可藉由以管材連結複數膨脹部3 成軸向相互連結狀態，形成具有複數膨脹部3的膨脹灌漿 螺栓1 A。 其次，對使用上述圖1〜圖4 A、4 B所說明的膨脹灌漿螺 栓1 A的本發明之一灌漿工法例加以說明。 圖5〜圖9係顯示本發明灌漿工法的順序的第1例的圖 式，圖5係顯示削孔的形成步驟的圖式，圖6A及圖6B係 11 312XP/發明說明書(補件)/94-05/941 〇2434When the sealing material 13 is provided, the expansion portion 3 expands and adheres to the floor via the sealing material 13, so that the sealing property can be improved, and the leakage of the curable grout material or the water stop can be prevented. indeed. In the present embodiment, although the sealing member 13 is provided near the rear end portion and near the front end portion, it may be only the sealing member 13 near the rear end portion or the sealing member 13 may be provided at three or more places. Further, the inlet sleeve 2 of the expansion grouting bolt 1 A of this example constitutes a series of expansion portions 3 slightly in front, but the rear end portion or the front end portion of the expansion portion 3 is shown as a simple pipe of an appropriate length, leaning against the front end. The expansion portion 3 is provided on the side of the side or the rear end portion, or the expansion grouting bolt 1 A having the plurality of expansion portions 3 may be formed by connecting the plurality of expansion portions 3 in the axial direction to each other by the pipe. Next, a grouting method of one of the inventions using the expanded grouting bolt 1 A described with reference to Figs. 1 to 4A and 4B will be described. 5 to 9 are views showing a first example of the procedure of the grouting method of the present invention, and Fig. 5 is a view showing a step of forming a hole, and Figs. 6A and 6B are 11 312 XP/invention (supplement)/ 94-05/941 〇 2434

FIG. 7A is a view showing a swelling bolt in which an expansion portion is expanded in a hole, and FIG. 7B is an enlarged sectional view showing an expansion portion of FIG. 7A. FIG. 8A to FIG. 8C are diagrams showing a pouring inlet forming step. Fig. 8A is a diagram showing an expansion grouting bolt for filling an inlet opening in a hole, and Fig. 8B is an enlarged perspective view of a vicinity of an inlet opening portion of the opening immediately before the opening of the inlet. A magnified view of the vicinity, and Fig. 9 shows a pattern of the pouring step of the hardened grout. In the drawings, the same reference numerals as in the above-mentioned Figs. 1 to 4A and 4B denote the same structural portions. First, as shown in Fig. 5, the hole drill bit 14 is formed to form a desired depth hole 15. After the hole 15 is formed, as shown in Fig. 6A, the expansion grouting bolt 1 A is inserted into the ground hole 15 from the front end side (the port forming portion 9 A side) into the ground. In this state, the expansion grouting bolt 1 A is as shown by the circle 6 A and the expansion portion 3 does not expand, and is inserted into the hole 15 in a state where the expansion portion 3 and the sealing member 13 are in a sufficient state. When the expansion grouting bolt 1A is inserted into the foundation, it is necessary to form 15 for a soft foundation such as clay, or a hole may not be formed. 5 5. Insert the expansion grout bolt 1 A into the mantle 6 by directly pushing it with a heavy machine or the like. The 16 shown in Fig. A is used to fasten the pressure feed hose 1 7 (refer to the accessories in the figure, which is used to supply pressure to the expansion grouting bolt 1A for 312XP/invention manual (supplement)/94-05/ 94102434 'Expanded expansion of the expansion, shown in the display, the figure of these pieces or the cutting into, Figure 6 B around the hole, by k 0 7A) to the hole 12 1335377 1 8, can be connected to the supply The pressure feed hose 1 7 is connected in the state of the hole 18. The fitting 1 6 is formed by screwing the screwing portion 44 into the screw portion 5 of the inlet sleeve 2 provided in the expansion grouting bolt 1 A. The fitting of the fitting 16 can be carried out before the expansion grouting bolt 1 A is inserted into the cutting hole 15 or after the insertion.
其次，如圖7 A所示，連結壓送軟管1 7於上述配件1 6， 自壓送軟管 1 7，經由配件 1 6，施加内壓於膨脹灌漿螺栓 1 A。該内壓以流體壓力施加。雖然可藉例如壓縮空氣等加 壓氣體進行，不過，一般以容易施加大壓力的加壓液體， 特別是加壓水較佳。 由於如圖7 B所示，膨脹灌漿螺栓1 A的膨脹部3藉上述 内壓徑向膨脹，密貼削孔 1 5 的内周面，故即使在自削孔 1 5湧出水情況下，仍可對此止水。特別是由於在密封材1 3 設置處，該密封材1 3提高密貼狀態，故可更加提高止水效 果。又，即使在周圍地基脆弱情況下，仍可藉由該膨脹部 3的膨脹，獲得某一程度的膨脹灌漿螺栓1 A的固定力。 上述膨脹部3的膨脹以利用較灌入口 7 (參照圖8 A及圖 8 C )於灌入口形成部9 A開口的壓力低的壓力來進行較佳。 具體而言，以利用較獲得期望膨脹所需最低壓力高，較使 圖8A及圖8C所示灌入口 7於灌入口形成部9A開口的壓力 低的壓力進行較佳。若於膨脹部3的膨脹未結束期間灌入 口 7開口 ，即發生内壓洩漏，必須供給高於該洩漏的内壓 (供給加壓水），難以進行膨脹作業。 於膨脹灌漿螺栓1 A的膨脹部3膨脹必要量之後，藉由 13 312XP/發明說明書(補件)/94-05/941 〇2434 1335377 供給更高壓力，使圖8A及圖8C所示灌入口 7於灌入口形 成部9A開口。 對上述灌入口形成部9A中灌入口 7的開口機制加以說 明。Next, as shown in Fig. 7A, the connection pressure feed hose 17 is applied to the above-mentioned fittings 16, and the self-pressurizing hoses 17 are applied to the expansion grouting bolts 1A via the fittings 16. This internal pressure is applied as a fluid pressure. Although it can be carried out by a pressurized gas such as compressed air, it is generally preferred to use a pressurized liquid which is easy to apply a large pressure, particularly pressurized water. As shown in Fig. 7B, the expansion portion 3 of the expansion grouting bolt 1 A is radially expanded by the above internal pressure, and is closely attached to the inner peripheral surface of the hole 15 , so even in the case where the water is poured out from the hole 15 This can stop the water. In particular, since the sealing member 13 is provided in a sealed state at the place where the sealing member 13 is disposed, the water stopping effect can be further enhanced. Further, even in the case where the surrounding foundation is weak, a certain degree of fixing force of the expansion grouting bolt 1 A can be obtained by the expansion of the expansion portion 3. The expansion of the expansion portion 3 is preferably performed by a pressure lower than the pressure at which the inlet port 7 is opened by the inlet 7 (see Figs. 8A and 8C). Specifically, it is preferable to use a pressure lower than the minimum pressure required to obtain the desired expansion, and a pressure lower than the pressure at which the inlet 7 of the inlet port forming portion 9A is opened as shown in Figs. 8A and 8C. When the filling port 7 is opened during the expansion of the expansion portion 3, the internal pressure leaks, and it is necessary to supply an internal pressure higher than the leakage (supply pressurized water), making it difficult to perform the expansion operation. After the expansion portion 3 of the expansion grouting bolt 1 A is expanded by the necessary amount, the higher pressure is supplied by 13 312XP/invention specification (supplement)/94-05/941 〇 2434 1335377, so that the inlets shown in Figs. 8A and 8C are filled. 7 is opened at the inlet opening forming portion 9A. The opening mechanism of the filling port 7 in the above-described filling inlet forming portion 9A will be described.
首先，如於圖4A、4B中說明，本例之膨脹部3前端部 施加雖未擴徑，卻自壓陷部 8的壓陷口向左右張開的力 量，藉此，可經由上述開縫1 2，使加壓套筒1 0破碎。因 此，若供給較獲得膨脹所需壓力更高的壓力，即如圖 8B 所示，膨脹部3前端經由上述開縫1 2，使加壓套筒1 0破 碎，左右張開，一面熔接部11隨著加壓套筒10變形而變 形，一面露出壓陷部8 (參照圊1 )的底部。而且，藉内壓， 圖中箭頭所示方向的力量作用於壓陷部8的底部附近處。 因此，該力量作用，形成於壓陷部8底部附近的上述脆化 部破裂，圖8C所示灌入口 7開口。由於如上述，特別是壓 陷部8的底部附近藉由形成時的加工硬化脆弱化，且若加 壓套筒10破碎，即容易施加大的力量，故適於作為脆化部。 由於在上述灌入口 7開口後，依需要解除内壓（由於排 出加壓用水），故經由壓送軟管1 7，仍舊裝上配件1 6，或 卸下配件1 6，自入口套筒2供給硬化性灌漿材。作為該硬 化性灌漿材，可使用例如水泥水懸浮液、膨潤土-水玻璃懸 浮液、水玻璃水溶液、路尼格林水溶液、尿素樹脂水溶液、 丙烯酸胺水溶液 '丙烯酸鹽系水溶液、胺甲酸乙酯樹脂液 等，可按照地基的性質狀態等選擇。 由於在該硬化性灌漿材灌入之際，如前述，密封地基與 14 312XP/發明說明書(補件)/94-05/94102434 1335377 膨脹灌漿螺栓1 A間的間隙，故可抑制硬化性灌漿材漏出， 可如圖 9所示，確實獲得期望的硬化性灌漿材灌入區域 1 9。又由於灌漿結束後，膨脹灌漿螺栓1 A仍舊留作鎖緊 螺栓，故即使水湧出，仍可藉由上述膨脹部3的膨脹的密 封，防止硬化性灌漿材的流出，確實謀得必要區域的地基 改良。First, as shown in FIGS. 4A and 4B, the distal end portion of the inflation portion 3 of the present embodiment is applied with a force that is not expanded, but is opened to the left and right from the depression of the indentation portion 8, thereby allowing the slit to be opened. 1 2, the pressurized sleeve 10 is broken. Therefore, if a pressure higher than the pressure required for the expansion is supplied, that is, as shown in FIG. 8B, the front end of the expansion portion 3 is broken by the slit 12, and the pressure sleeve 10 is broken, and the left and right sides are opened, and the welded portion 11 is welded. As the pressurizing sleeve 10 is deformed and deformed, the bottom of the depressed portion 8 (see 圊1) is exposed. Further, by the internal pressure, the force in the direction indicated by the arrow in the figure acts on the vicinity of the bottom of the depressed portion 8. Therefore, the force acts to break the above-mentioned embrittled portion formed near the bottom of the depressed portion 8, and the inlet 7 is opened as shown in Fig. 8C. As described above, in particular, the vicinity of the bottom portion of the depressed portion 8 is weakened by work hardening at the time of formation, and if the pressurizing sleeve 10 is broken, it is easy to apply a large force, and thus it is suitable as an embrittled portion. Since the internal pressure is released as needed after the opening of the inlet 7 is opened (due to the discharge of pressurized water), the fitting 16 is still attached via the pressure feed hose 17, or the fitting 16 is removed, and the inlet sleeve 2 is removed. Supply hardened grouting material. As the curable grouting material, for example, a cement aqueous suspension, a bentonite-water glass suspension, a water glass aqueous solution, a Renegreen aqueous solution, a urea resin aqueous solution, an aqueous acrylamide aqueous solution, an acrylate aqueous solution, or an urethane resin liquid can be used. Etc., can be selected according to the nature of the foundation, and the like. Since the hardened grouting material is poured in, as described above, the sealing foundation and the gap between the expanded joint of the grouting bolt 1A of the 14 312XP/invention specification (supplement)/94-05/94102434 1335377 can inhibit the hardening grouting material. Leakage, as shown in Fig. 9, can surely obtain the desired hardened grouting material filling area 19. Moreover, since the expansion grouting bolt 1A is still used as the locking bolt after the grouting is completed, even if the water is poured out, the expansion of the expansion portion 3 can prevent the outflow of the hardened grouting material, and the necessary area is surely obtained. Foundation improvement.
硬化性灌漿材的灌入雖可藉由灌入單一種類的硬化性 灌漿材來進行，不過，亦可於途中，切換硬化性灌漿材的 種類，灌入複數種硬化性灌漿材。作為複數種硬化性灌漿 材的組合例，可列舉最初灌入滲透性佳的硬化性灌漿材， 在促進對大範圍的灌入之後，灌入滲透性雖不佳，硬化後 的強度卻高的硬化性灌漿材，謀求提高周圍強度，或者， 於水湧出場所，最初灌入硬化時間（膠凝時間）短的硬化性 灌漿材，在抑制水湧出之後，灌入硬化時間長的硬化性灌 漿材，謀求對周圍滲透等。 上述例子雖係灌入口形成部9 A具備加壓套筒1 0者，不 過，亦可為不設置加壓套筒1 0的構造。亦即，除了設置加 壓套筒1 0以外，亦可為與上述相同的構造。然而，以構成 為了容易調整灌入口 7(參照圖8A及圖8C)的形成壓力，設 置加壓套筒10，於達到既定壓力以上時，加壓套筒10破 碎，大的力量作用於跪化部的構造較佳。 圖1 0係顯示灌入口形成步驟的其他例子的圖式，符號 僅顯示要部。 於本例中，在圖5〜圖7 A、7 B所說明的削孔步驟、插入 15 312XP/發明說明書(補件)/94-05/94102434 1335377Although the filling of the hardened grouting material can be carried out by pouring a single type of hardening grouting material, it is also possible to switch the type of the hardening grouting material and to pour a plurality of hardening grouting materials on the way. As a combination example of a plurality of kinds of curable grouting materials, a hardenable grouting material which is excellent in permeability at the beginning of the pouring is mentioned, and after a large-scale infusion is promoted, although the permeability is poor, the strength after hardening is high. A hardenable grouting material is used to improve the surrounding strength. Or, in a place where water is poured out, a hardening grouting material having a short hardening time (gelling time) is initially injected, and after the water is prevented from flowing out, a hardening grouting material having a long hardening time is poured. , seeking to infiltrate around and so on. In the above example, the inlet forming portion 9A is provided with the pressure sleeve 10, but the pressure sleeve 10 may not be provided. That is, in addition to the provision of the pressurizing sleeve 10, the same configuration as described above may be employed. However, in order to easily adjust the forming pressure of the inlet 7 (see FIGS. 8A and 8C), the pressurizing sleeve 10 is provided, and when the pressure is equal to or higher than the predetermined pressure, the pressurizing sleeve 10 is broken, and a large force acts on the crucible. The structure of the part is better. Fig. 10 is a diagram showing another example of the filling inlet forming step, and the symbol only shows the main portion. In this example, the hole cutting step illustrated in Fig. 5 to Fig. 7 A, 7 B, insert 15 312XP / invention manual (supplement) / 94-05/94102434 1335377
步驟及膨脹步驟後，自膨脹灌漿螺栓1 A的入口套筒2卸下 壓送軟管17及配件16，取而代之，自入口套筒2將棒狀 開孔具6插入膨脹灌漿螺栓1 A内，安裝作動開孔具6的作 動裝置2 0於入口套筒2，藉開孔具6突出膨脹灌漿螺栓1 A 的前端部，使灌入口 7開口。如此，即使在萬一昇高壓力， 灌入口 7無法形成於灌入口形成部9A情況下，仍可確實形 成灌入口 7。又，若進行此種灌入口形成步驟，即使未預 先設置灌入口形成部9A，仍可藉由在膨脹步驟後，以開孔 具6強制性形成灌入口 7，進行圖9所示此後灌入步驟。 除了單純棒狀體外，可使用前端銳利的棒狀體、鑽狀棒 狀體等作為開孔具 6，可使用油壓裝置等作為作動裝置。 於使用開孔具 6情況下，雖以容易插入膨脹灌漿螺栓 1 A 内，後端部的開口軸向張大較佳，不過，在膨脹灌漿螺栓 1 A後端部的開口小情況下，亦可於膨脹步驟後，切斷後端 部，擴大開口部，插入開孔具6。特別是，若於入口套筒2 形成螺紋部5，即可螺接油壓千斤頂等作動裝置20於入口 套筒 2，承受反作用力，可正確地將壓入力量作用於開孔 具6。 圖1 1係顯示灌入口形成部的第2例的剖面圖。 本例之灌入口形成部9 B藉栓體2 1閉塞預先形成於膨脹 部3的灌入口 7。 於上述灌入口形成部 9B情況下，若例如以延展性較構 成膨脹部3的材料小的材料構成該栓體2〗，藉由熔接等使 拴體2 1與膨脹部3 —體化，即可於膨脹部3膨脹時，集中 16 3】2XP/發明說明書(補件)/94-05/94102434 1335377 應力於栓體2 1部分，在進一步昇高壓力時破裂，使灌入口 7開口 。又，在作成以所需内壓卸下拴體21的螺入式，或 使用加壓水於内壓的供給情況下，藉水溶性黏接劑使栓體 2 1與膨脹部3 —體化，以所供給加壓水減弱黏接力，使之 破裂。該栓體21的灌入口形成部9 B不僅容易設於膨脹部 3的前端部，亦容易設於膨脹部3的靠近後端處或中間部。 圖1 2係顯示灌入口形成部的第3例的剖面圖。After the step and the expansion step, the pressure feed hose 17 and the fitting 16 are removed from the inlet sleeve 2 of the expansion grouting bolt 1 A, and the rod-shaped opening 6 is inserted into the expansion grouting bolt 1 A from the inlet sleeve 2, The actuating device 20 for mounting the actuating opening device 6 is at the inlet sleeve 2, and the front end portion of the expansion grouting bolt 1 A is protruded by the opening hole 6 to open the filling port 7. Thus, even in the case where the inlet 7 cannot be formed in the inlet forming portion 9A in the event of an increase in pressure, the inlet 7 can be surely formed. Further, if such an inlet forming step is performed, even if the filling inlet forming portion 9A is not provided in advance, the filling inlet 7 can be forcibly formed by the opening member 6 after the expansion step, and the filling as shown in Fig. 9 can be performed. step. In addition to the simple rod-shaped outer body, a sharp-edged rod-shaped body, a drill-shaped rod-shaped body or the like can be used as the opening means 6, and a hydraulic device or the like can be used as the acting means. In the case of using the venting device 6, although it is easy to insert into the expansion grouting bolt 1 A, the axial opening of the rear end portion is preferably increased, but in the case where the opening of the rear end portion of the expanded grouting bolt 1 A is small, After the expansion step, the rear end portion is cut, the opening portion is enlarged, and the opening device 6 is inserted. In particular, if the threaded portion 5 is formed in the inlet sleeve 2, the actuator 20 such as the hydraulic jack can be screwed to the inlet sleeve 2 to receive the reaction force, and the pressing force can be correctly applied to the opening member 6. Fig. 1 is a cross-sectional view showing a second example of the inlet forming portion. The inlet forming portion 9B of this example occludes the inlet 7 previously formed in the expansion portion 3 by the plug body 2 1 . In the case of the above-described irrigation inlet forming portion 9B, for example, the plug body 2 is formed of a material having a ductility smaller than that of the material constituting the expansion portion 3, and the body 2 1 and the inflation portion 3 are formed by welding or the like, that is, When the expansion portion 3 is inflated, the concentration of the plug portion 21 is increased by the pressure of the plug portion 21, and the irrigation inlet 7 is opened. Further, in the case of the screw-in type in which the cartridge 21 is removed by the required internal pressure, or the supply of the pressurized water in the internal pressure, the plug body 21 and the inflation portion 3 are integrated by the water-soluble adhesive. The weakened adhesive force is weakened by the supplied pressurized water to cause it to rupture. The inlet forming portion 9B of the plug body 21 is not only easily provided at the front end portion of the expansion portion 3, but also easily provided at the rear end portion or the intermediate portion of the expansion portion 3. Fig. 1 is a cross-sectional view showing a third example of the inlet forming portion.
本例的灌入口形成部9C設置連接於膨脹部3前端，實 質上不會因内壓而擴徑的管狀蓋材保持部2 2，以蓋材保持 部2 2的前端開口作為灌入口 7，利用藉環狀蓋2 3安裝於 蓋材保持部22前端的蓋材24閉塞該灌入口 7。 於上述灌入口形成部9C情況下，可使蓋材24具有在所 需内壓下破裂的強度，於膨脹部3膨脹後，昇高内壓，使 該蓋材24破裂，令灌入口 7開口。又由於該蓋材24容易 藉圖1 0所說明的開孔具6扎破，故本灌入口形成部9 C特 別適於圖1 0所說明的灌入口形成步驟的其他例子。 圖1 3係顯示灌入口形成部的第4例的剖面圖。 本例的灌入口形成部9 D使用與圖1〜圖4 A、4 B所說明 者相同的加壓套筒1 0，填隙安裝加壓套筒1 0於對應預先 形成在膨脹部3的灌入口 7的位置，以該加壓套筒1 0閉鎖 灌入口 7。又，於加壓套筒1 0兩端形成開縫1 2。 於上述灌入口形成部9D情況下，在膨脹部3膨脹時， 抑制加壓套筒1 0填隙安裝部分的膨脹，使此部分不擴大膨 脹，膨脹其他膨脹部 3，此後，進一步昇高内壓，藉由加 17 312XP/發明說明書(補件)/94-05/94102434The inlet port forming portion 9C of the present example is provided with a tubular lid member holding portion 2 2 that is connected to the tip end of the expansion portion 3 and which does not substantially expand the diameter by the internal pressure, and the front end opening of the lid member holding portion 2 2 serves as the inlet port 7, The filling port 7 is closed by a lid member 24 attached to the front end of the lid member holding portion 22 by the annular cover 23. In the case of the above-described filling inlet forming portion 9C, the lid member 24 can have a strength to be broken under a desired internal pressure. After the expansion portion 3 is expanded, the internal pressure is raised to break the lid member 24, and the filling port 7 is opened. . Further, since the lid member 24 is easily punctured by the opening member 6 described with reference to Fig. 10, the inlet port forming portion 9 C is particularly suitable for the other example of the inlet forming step illustrated in Fig. 10 . Fig. 1 is a cross-sectional view showing a fourth example of the inlet forming portion. The filling inlet forming portion 9 D of this example uses the same pressing sleeve 10 as that described with reference to Figs. 1 to 4A, 4B, and the caulking mounting pressurizing sleeve 10 is formed in advance in the expansion portion 3 corresponding thereto. The position of the inlet 7 is filled with the pressurized sleeve 10 to lock the inlet 7. Further, a slit 1 2 is formed at both ends of the pressurizing sleeve 10 . In the case of the above-described filling inlet forming portion 9D, when the expansion portion 3 is expanded, the expansion of the caulking mounting portion of the pressurizing sleeve 10 is suppressed, so that the portion does not expand and expand, and the other inflating portion 3 is expanded, and thereafter, the inside is further raised.

Further, in order to surely reach the closed state of the inlet 7 before the crushing of the sleeve 10, a gasket (not shown) for sealing the inlet 7 may be interposed between the pressure sleeve 10 and the expansion portion 3. The inlet inlet forming portion 9 D is not only easily provided at the front end portion of the expansion portion 3 but also easily provided at the rear end portion or the intermediate portion of the expansion portion 3. Fig. 1 is a view showing a second example of the expansion grouting bolt of the present invention, omitting a perspective view of the middle portion, and Fig. 15 is an explanatory view showing a state in which an internal pressure for opening the opening of the inlet portion is shown by a packing member. Only the highlights. The expansion grouting bolt 1 of this example is closed by the locking cover 25, and a plurality of embedded plugs are axially disposed at an intermediate portion of the expansion portion 3 at a proper interval to the inlet forming portion 9 of the pre-formed inlet 7. Refer to Figure 1 5). The filling port forming portion 9 is also opened by the expansion portion 3 to raise the internal pressure, and the body 21 is opened to open the inlet port 7, which is the same as that shown in Fig. 11. On the other hand, in the case of the expansion plug 1 Β having the plurality of inlet forming portions 9 所示 as shown in Fig. 14, there is a possibility that the inlets 7 of all the inlet forming portions (see Fig. 15) may not be opened at the inner pressure. The opening periods are staggered, and the filling port 7 which is pressed from the opening is lost, so that all the filling ports 7 are not in the mouth. In order to prevent the internal pressure from escaping when the inlet 7 is opened, and optionally only a part of the inlet 7 is opened, as shown in Fig. 15, it is preferable to apply the internal pressure locally by using the packing member 26. Further, first, the internal pressure required to expand the expansion portion 3 is applied, and the expansion portion 3 is expanded as shown in Fig. 7A. Thereby, the indentation portion 8 is extended, and the internal space of the expansion portion 3 is expanded to be close to a circular shape. In this state, from the figure 312 ΧΡ / invention manual (supplement) / 94-05 / 94102434 plus irrigation and also 14 expansion 2 1 the pulp 9 Β inside the structure) 18 18 14 1335377 shown the inlet sleeve 2 As shown in Fig. 15, the filling pipe 27 (the pipe with the double packing member) with the packing member 26 attached to the front and the rear is inserted into the expansion grouting bolt 1 B.

The expansion and clamping inlet forming portion 9 B seals the axial direction of the expansion grouting bolt 1 B. In this state, the pressurized fluid is supplied from the filling pipe 27 to the region sandwiched by the two packing members 26. If the expansion grouting bolt 1 B is locally pressurized, the two packing members 26 can be surely and selectively lost. The irrigation inlet 7 of the filling inlet forming portion 9B of the position is opened. Further, by releasing the pressure of the packing member 26, the pouring pipe 27 to which the packing member 26 is attached can be easily moved in the axial direction of the expansion grouting bolt 1B. As described above, the self-completion inlet forming portion 9B selectively opens the inlet 7 so that not only all of the plurality of inlets 7 can be reliably opened, but also only a portion of the inlets 7 can be selectively opened, or via different irrigation ports. 7. Fill in different types of hardened grouting materials. For example, after only the opening 7 near the front end portion is opened and poured into the hardened grouting material, the hardened grouting material in the expanded grouting bolt 1 B is rinsed when it is not hardened, or is removed after hardening. Secondly, the irrigation inlet 7 near the rear end portion is opened, and if necessary, a plugging material is applied to the front end portion, and then different kinds of hardening grouting materials are poured into the axial direction of the expanding grouting bolt 1 B. Hardened grouting material. Further, the inflated portion 3 which is insufficiently expanded may be re-expanded by partial pressurization using the packing member 26 described above. Fig. 16 shows a third example of the expansion grouting bolt of the present invention, and a perspective view of the middle portion 19 312XP/invention specification (supplement)/94-05/94102434 1335377 is omitted, and the symbol only shows the main portion. The expansion grouting bolt 1 C of this example is formed at the front end with a hole drill tap 28 . If the above-mentioned hole-drilling tap 2 8 is provided, the hole-drilling tap 2 8 can be used to form the cut-out hole 15 (see FIG. 5), and the expansion grouting bolt 1 C can be inserted into the-cut hole 1 5 at the same time. Shorter working hours. Next, a fourth example of the expansion grouting bolt of the present invention will be described.

As shown in Fig. 17 and Figs. 18A, 18B, the expansion grouting bolt 1D of this example has an expansion portion 3, and a cover 30 composed of a cover sleeve 29 and a cover 30 for closing the front end of the sleeve 29 The inlet forming portion 9E. Further, the front end sleeve 3 1 and the rear end sleeve 3 2 are caulked and attached to the front end portion and the rear end portion of the expansion portion 3, respectively. In the front end sleeve 31, the rear end portion of the cover sleeve 29 of the inlet opening forming portion 9E is integrated with the welded portion 33, and the rear sleeve 32 is integrated with the inlet sleeve 2 by the welded portion 34. The inlet sleeve 2 is a member in which the screw portion 5 is formed inside, and is the same as the example described with reference to Figs. 1 to 4A and 4B. Further, the 3 5 is used to mount the convex portion of the flat plate 36 (refer to Fig. 28A) at the time of fixing the expansion grouting bolt 1 D to the foundation. As can be seen from the cross-sectional view shown in Fig. 19B, the expansion portion 3 of the expansion grouting bolt 1D of the present example is inwardly pressed inward in a part of the circular tube, and has a portion of the indentation portion 8 which is partially pressed into the circular tube.

As shown in FIG. 19A, in order to prevent the internal pressure from leaking to the outside when the internal pressure is applied to the expansion grouting bolt, and to suppress the diameter expansion, the rear end of the expansion portion 3 is filled with the indentation portion 8 by the welded portion 37. The outer space between the rear end sleeves 3 2 is again shown in FIG. 19 C. In order to suppress the diameter expansion, the front end portion of the expansion portion 3 is borrowed from the joint portion 38 to fill the gap between the indented portion 8 and the front end sleeve 3 1 . External space. The constituent material of the expansion portion 3 of the expansion grouting bolt 1 D of this example is the same as that of the expansion grouting bolt 1 A illustrated in Figs. 4A and 4B. The cover for the front end portion of the expansion grouting bolt 1 D of this example is provided with a sleeve 2 9 . The inlet forming portion 9 E of the cover 30 is an integrally formed body, and the wall thickness between the cover sleeve 9 9 and the cover 30 is formed. Very thin, by the internal pressure, the thin-walled crushing cover 30 is separated from the cover sleeve 29, and the inlet 7 can be opened at the front of the expansion grouting bolt 1D. The same material as the above-described expansion portion 3 can be used as the lid 30 for the cover sleeve 29, and can be constructed by a predetermined internal pressure, specifically, by a higher internal pressure when the expansion portion 3 is expanded, so that the cover 30 can be used for the cover. The sleeve 29 can be separated.

First, as shown in Fig. 27, the hole 15 is formed on the foundation. The hole drill of the drill carriage that can be used is equal to the formation of the hole 15 . After the hole 15 is formed, as shown by 囷28 A, by inserting from the front end side, the flat plate 36 is inserted into the above-mentioned hole 15 to the convex portion 3 5 and the expansion grout bolt 1 D is inserted into the foundation. In this state, as shown in Fig. 28B, the expansion portion 3 of the expansion grouting bolt 1D does not expand, and in the state where there is a margin between the inner wall of the hole and the hole 15, the hole 1 is inserted, and then, as shown in Fig. 29A. The mounting fitting 16 is applied to the fitting 16 at an inlet sleeve crimping hose (not shown), and an internal pressure is applied to the expansion 1 D. This internal pressure is applied as a fluid pressure. Although it may be carried out by a pressurized gas such as a gas, it is generally preferable to apply a large pressurized liquid, particularly pressurized water. As shown in Fig. 2 6 A, the fitting 16 has a screwing portion 4 4 which can expand the grouting bolt 1 D by screwing the screwing portion 44 into the inlet sleeve 2 of Fig. 17. The fitting 16 has a supply hole 18 for supplying pressure into the bolt 1 D, and is configured to be connected to the feed hole and to connect a pressure feed hose (not shown). The fitting 16 can be installed before the insert of the slurry bolt 1 D into the hole 15 or as shown in Fig. 26B, or without the inlet sleeve 2, directly melting the 312XP/invention specification (supplement)/94- 05/94102434 Fig. 2 9 B shows the drawing in Fig. 29 A, and uses the general side (28A of the position of the cover 30 and the figure in the expansion part 5. 2.

As shown in Fig. 29B, the expansion grouting bolt 1D is radially expanded by the above-mentioned expansion portion 3, and is closely attached to the inner wall of the hole 15b. Therefore, even when the hole 15 is poured out, the water can be stopped. Further, even in the case where the expansion portion 3 is weakened by the expansion, the fixing force of the certain expansion grouting bolt 1 is obtained. The expansion of the expansion portion 3 is preferably performed at a lower pressure than the pressure of the cover 30 from the cover. When the expansion portion 3 is not completed, the cover 30 is separated from the cover sleeve 29, that is, the internal pressure leaks therefrom, and the internal pressure (supply pressurized water) above the leakage is supplied, and the operation is difficult. The expansion portion 3 of the expansion grouting bolt 1 D is expanded by a necessary amount to supply a higher pressure. As shown in Fig. 30, the cover 30 is sleeved from the cover to the front end of the expansion grouting bolt 1 D to open the inlet 7. Thereafter, after the internal pressure is released as needed (after the pressurized water is discharged: the fitting 16 is attached by a pressure feed hose (not shown), or the distribution inlet sleeve 2 is removed to supply the curable grout. In the grouting method of the expanded grouting bolt of the first example of the grouting material, since the hardening grouting material is poured, as described above, the gap between the densely-expanded grouting bolts 1 D can suppress the hard grouting grouting portion. The hardened grouting material can be poured into the deepest part of the cutting hole 15. After the end, the expansion grouting bolt 1D is also reserved as a locking bolt, so that it can still be prevented by the expansion sealing of the expansion portion 3 described above. The slurry material is discharged, and the ground improvement of the necessary area is indeed obtained. 312ΧΡ/Invention Manual (supplement)/94-〇5/94丨〇2434 The internal pressure is sufficient to separate the expanded β 2 9 from the surrounding ground. After the opening is vented for swelling, by separating 29, the slab is still free to pass through the slab and the material is leaked out due to water swelling. 25 1335377 Although in this case, hardening grouting Material can also be poured into a single A variety of hardenable grouting materials are used, but a variety of hardening grouting materials can be poured in the middle of the process, and a plurality of types of hardening grouting materials can be poured in. The combination of the plurality of hardening grouting materials is also expanded by using the first example. The grouting bolts are described in the grouting legislation.

As shown, the grouting method using the expansion grouting bolt 101 of the present invention can be used for the stabilization of the foundation of the excavation section 103 in the tunnel engineering, the reinforcement of the ceiling portion near the excavation section 10 3 and the arched concrete constituting the inner wall of the tunnel. The foot is strengthened. In the tunnel project, the expansion grouting bolt 1 0 1 was inserted into the foundation surface shortly after excavation, and the hardened grouting material was poured into it to stabilize the foundation of the excavated tunnel and stabilize the foundation after the excavation. However, the ground surface that has just been exposed through excavation is prone to loosening. Therefore, when the hardenable grouting material is poured, loosening occurs near the entrance of the hole in which the expanded grouting bolt 10 1 is inserted, and the hardened grouting material leaks. However, according to the present invention, as described above, the expansion portion can be inflated to be closely attached to the inner surface of the hole and sealed. Moreover, since the water that is poured out can be sealed at the same time, it is possible to greatly improve the work in the tunnel work while performing the reverse drilling and the base reinforcement.
