    [30] 1 is a schematic perspective view of a lightweight precast concrete panel 110 and a precast concrete panel 114 for repairing concrete concrete according to the present invention. When the structure is a lightweight precast concrete panel 110, the lightweight concrete layer 111 And a reinforcing means 112 for reinforcing the lightweight concrete layer 111 and the precast concrete panel 114, the reinforcing means 112 for reinforcing the concrete layer 115 and the concrete layer 115. Is formed.
    [31] Cement as a material for forming the lightweight precast concrete panel 110 or the precast concrete panel 114 may be selected from port cement, back cement, and color cement to be suitable for the concrete sphere 210 to be repaired. have.
    [32] A component that distinguishes the lightweight precast concrete panel 110 from the precast concrete panel 114 is an aggregate forming the panel. The lightweight precast concrete panel 110 is a panel using lightweight aggregate as the aggregate, the lightweight aggregate is perlite (perlite), filite (cite), celite (ALC) aggregate and ALC ( ALC) Select one of the crushed aggregates to use. And the precast concrete panel 114 is formed by adjusting the mixing ratio and the like to use aggregates used to form the general concrete and to meet various conditions such as compressive strength of the concrete concrete to be repaired.
    [33] As described above, the lightweight precast concrete panel 110 of the present invention is classified according to the type of cement, the type of lightweight aggregate to form the lightweight concrete layer 111, and also divided according to the type of the reinforcing means 112. Can be. The reinforcing means 112 may be divided into two types that are coupled to or included in one surface of the lightweight concrete layer 111.
    [34] First, the lightweight precast concrete panel 110 including the reinforcing means 112 coupled to one surface of the lightweight concrete layer 111 is a high-strength mortar epoxy resin on one surface of the lightweight concrete layer 111 that is cured and poured. And a panel formed by pouring a mixture of a curing agent. When the reinforcing means 112 is hardened, the light weight precast concrete panel 110 may be forced by steam curing to increase its strength.
    [35] The lightweight precast concrete panel 110 in which the reinforcing means 112 is included in the light weight concrete layer 111 has the light weight concrete layer 111 as the upper light concrete layer and the lower light weight with the reinforcing means 112 as the boundary. It can be divided into concrete layers. The lightweight precast concrete panel 110 may be classified into two types according to the aspect in which the lightweight precast concrete panel 110 is formed. One is that the lightweight concrete layer 111 is formed in the form of the other, the cured panel and the panel is formed while being combined with the reinforcing means 112 and the lightweight concrete layer 111 is not formed in the form of the panel Before the other hardening means that the reinforcing means 112 is impregnated and concrete is poured again and combined with the reinforcing means 112. The lightweight precast concrete panel 110 may also be hardened after curing and forced to increase its strength.
    [36] As described above, the lightweight precast concrete panel 110 of the present invention may be classified according to the reinforcing means 112. The reinforcing means 112 may include prepreg unidirectional carbon fibers, anhydrous bidirectional woven carbon fibers, aramid fibers, Any one of the glass fibers is selected and bonded between the upper and lower lightweight concrete layers 111 by impregnating the epoxy resin main material and the curing agent. The manufacturing process will be described in more detail.
    [37] The mold is manufactured according to the width and depth of the damaged part 221 of the concrete sphere and a release film is attached to the mold surface. And the mold is selected from any one of the portland cement, back cement, color cement, and any one of the light weight aggregate (perlite, fillite, celite, ALC aggregate, ALC fracture aggregate) and water in a predetermined mixing ratio As a result of mixing, placing and curing, the upper and lower lightweight concrete layers 111 are formed in a panel form. The impregnating epoxy resin main agent and the curing agent are mixed at a predetermined compounding ratio, and then thinly applied to one surface of the lower lightweight concrete layer. Immediately after applying the epoxy resin for impregnation, any one of the prepreg unidirectional carbon fiber, anhydrous bidirectional woven carbon fiber, aramid fiber, and glass fiber is selected and impregnated into the epoxy resin. Bubbles generated during impregnation are removed and the epoxy resin base and hardener for top impregnation are applied again. The lightweight precast concrete panel 110 is formed by bonding the upper lightweight concrete layer immediately after applying the top coat-impregnated epoxy resin. The lightweight precast concrete panel 110 may be formed by impregnating the glass fiber mesh in an uncured state and immediately pouring the upper lightweight concrete layer in addition to the method of hardening and bonding the lightweight concrete layer 111.
    [38] Unlike the above-mentioned lightweight precast concrete panel 110, the precast concrete panel 114 is used for forming aggregates, not lightweight aggregates. The lightweight precast concrete panel 110 is very advantageous in construction because of the light weight, but because of the use of lightweight aggregate, there is some limitation in its strength. The precast concrete panel 114 may be applied when the repair portion of the concrete sphere 210 requires more than a certain compressive strength. The precast concrete panel 114 includes reinforcing means 112 formed and coupled between the upper and lower concrete layers 115 and the upper and lower concrete layers 115. As described above, the concrete layer 115 is formed by mixing aggregate and cement and water used to manufacture general concrete. The cement is used by selecting any one of portland cement, back cement, and color cement. The upper and lower concrete layers 115 are placed and hardened to be combined with the reinforcement means 112 in the form of panels or the lower concrete layer is poured and the reinforcement means 112 is impregnated before the lower concrete layer is cured. It can be formed by pouring the upper concrete layer again. First, the reinforcing means 112 of the precast concrete panel in which the upper and lower concrete layers are added, hardened, and bonded and formed in a panel form is selected from among anhydrous bidirectional woven carbon fibers, prepreg unidirectional carbon fibers, glass fibers, and aramid fibers. Either one of the lower concrete layer in the form of the panel is formed by impregnating the epoxy resin main material and the curing agent as the impregnating means, and the epoxy resin main material and the curing agent is applied as a top coat and the panel form before the impregnation means is hardened. It is formed by combining the upper concrete layer. When the panel reinforcing means is a glass fiber mesh, the glass fiber mesh is formed in the lower concrete layer and then the upper concrete layer is poured again before the lower concrete layer is poured and cured. In order to make the glass fiber mesh have a stronger bonding force, the micro cement paste may be evenly laid on the surface of the glass fiber mesh before being impregnated. The hardened steam is cured after a predetermined time after being cured to further increase the strength of the precast concrete panel.
    [39] 2 to 5 is an elevation, cross section of the panel level adjustment and injection anchor of the present invention. As a method of use, the anchor is formed by using the body portion 120, the nut 123, the carrying clip 130, the injection pipe 140 as its component. The body portion 120 is a cylindrical shape having a hollow 125 as a whole, a male screw portion 121 is formed on an outer circumferential surface thereof, and forms a through hole 124 perpendicular to the hollow 125 at one end thereof, and the other end thereof. While forming the female threaded portion 133 on the inner circumferential surface of the hollow 125, the rectangular protrusion 122 is formed. The protrusion 122 may be formed in a hexagonal or octagonal shape. The male screw portion 121 formed on the outer circumferential surface of the body portion 120 is for screwing with the nut 123 and rotating the body portion 120 with the rotary tool combined with the protrusion 122 as shown in FIG. 4. The nut 123 fixed to the 110 moves in the longitudinal direction of the body 120 to adjust the level of the panel 110. In addition, the carrying clip 130 is formed of a cylindrical portion 131 having a female threaded portion 133 formed on an inner circumferential surface thereof and a ring portion 132 connected to the cylindrical portion 131 so that the nut 123 is screwed together. (120) the male thread portion 121 of the outer circumference serves as a ring to help carry the panel. The injection pipe 140 has a straw shape as a whole and has a male screw portion 141 formed at one end thereof. The female screw portion formed on the inner circumferential surface of the protrusion portion 122 of the body portion 120 and the male screw portion 141 of the injection pipe 140 are combined by screwing. Filling material is injected into the empty space on the rear surface of the panel through the injection pipe 140, the hollow 125 and the through hole 124. When the injection of the filler is finished, the injection pipe 140 is removed.
    [40] The panel level adjustment and injection anchor using the anchor for more detail how to install the concrete pavement 210 holding the damaged portion 221 will be described in more detail after the marking work to be slaughtered on the surface of the damaged road surface kat Cut using a whip. The damaged portion 221 of the surface of the concrete pavement is to be included in the cutting line 213, the cutting line 213 is to be a straight line and the cutting line 213 to form a right angle. The repaired part is cut out by using hydraulic or electric hammer. Placing the epoxy mortar 161 mixed by mixing a suitable ratio of synthetic resin and silica sand of the high adhesion force on the base surface 214 to the trapped base surface 214 to form a gap of about 10mm between the epoxy mortar coating surface and the panel to be installed Do pus work. The nut 123 of the anchor level for adjusting and injecting the panel is fixed to the anchor hole 113 formed in the concrete concrete repair panel 110 with a synthetic resin adhesive, and the body part 120 is attached to the nut 123. It is screwed together and the carrying clip 130 is screwed to the body portion 120 to transport the panel 110 to be seated in the trapped part. After removing the carrying clip 130, by rotating the body portion 120 as described above to equally adjust the level of the panel to match the concrete road surface. Since the nut 123 is fixed, the level of the panel is adjusted when the body 120 rotates. When the panel level adjustment is completed, the gap between the panel and the concrete pavement is sealed, and the low pressure injection cylinder 152 is installed at a predetermined position on the sealing portion, and the injection pipe 140 is installed at the anchor. Secondly, the injection pipe 140 is injected into the low pressure injection cylinder 152 to fill the voids on the rear surface of the panel with a synthetic resin filler such as an epoxy resin and to eliminate the occurrence of unfilled portions. When the injection operation is completed, the recessed portion such as the anchor hole 113 is finished by epoxy mortar or the like to complete the operation.
    [41] 6 to 8 illustrate a method of repairing a concrete sphere having a damaged portion, and the damaged portion 221 of the concrete sphere may have various kinds. There may be neutralization, material separation and deterioration due to aging of the concrete, and cracks 224 and leaks through the cracks 224 may occur as a result of construction defects at the time of concrete formation or due to the use environment. The sun is diverse as it occurs.
    [42] First, to determine the repair range of the damaged or leaked concrete surface due to aging, material separation, neutralization, deterioration, rock pocket (227), peeling of the existing concrete sphere so that the cutting line 213 is perpendicular to the straight line Do the cutting work. Debris removal work is performed more deeply by comparing the parts that are damaged due to cut aging, material separation, neutralization, deterioration, rock pocket (227), peeling, etc. with those that do not leak along the leakage path using electric hammer or other tools. do. When the exposed rebar 222 is damaged such as corrosion, the reinforcing bar is completely removed by using a sand grinder for removing rust, and then, a rust inhibitor is applied with a brush or the like. After the rebar rust removal and anti-rust treatment is completed, using a hammer drill, the injection packer hole 226 is drilled on the leaked portion. Packer hole 226 After the completion of the drilling operation to remove the dust inside the hole 226, and tightly tighten the injection packer 163 and at the same time fixed and installed using a high-pressure injector, such as filling. After the injection of the index agent 170 using the packer 163 is completed, the packer 163 is hit by a hammer or the like to be removed, and the surface dust and the like are neatly removed. Or plaster with a trowel. After 24 hours or more of completion of plastering work, check whether or not the re-leakage occurred, and then drill the multi-purpose anchor hole 223 using a hammer drill or the like and use an air pump or the like. 223) Remove dust and other foreign matter from inside. In addition, one of the multi-purpose anchors 130 and the concrete concrete repair panel 110 described above is selected and installed, and the level is evenly adjusted so that the surface deviation between the panel and the existing structure does not occur. The gap between the panel and the existing structure is sealed with an inorganic sealant and the multi-purpose anchor 130 serves as an air outlet so that the air outlet 142 is installed only in the gap between the upper panel. After the sealing material is cured, the wet adhesive grout 172 is injected from the lower multipurpose anchor 130 to the upper part using a high pressure injector, and after about 24 hours after the completion of the first injection, the low pressure injection is performed to complete the filling. Can be. After about 24 hours after the completion of the second injection, the construction is completed by finishing the recessed portion around the multipurpose anchor hole 113 formed in the panel, the portion where the air outlet 142 is installed, and other contaminated surfaces. When there is no leakage phenomenon in the concrete damaged part 221, the injection, application, plastering work of the water repellent may be excluded.
    [43] The present invention is to remove the defective part of the repair site of the concrete sphere completely and then install the repair panel as a fixed hardware, and the gap between the repair structure and the repair panel by injecting and filling the synthetic resin adhesive to adhere the existing plastering It completely eliminates the problems such as interface delamination between existing structures and repair materials due to work or spraying, and restores its performance efficiently and stably and provides semi-permanent durability. In addition, since one side of the panel is formed of lightweight concrete or concrete, it is very easy to maintain due to its excellent affinity with the structure to be repaired.
