Description

  In a tunnel on an automobile road, the interior of the supervisor passage below the handrail of the supervisor passage provided on the side wall of the tunnel is deteriorated and damaged due to long-term use, and this internal damage is the vertical wall of the supervisor passage. The tile wall is damaged. The present invention relates to a repair method for a damaged portion, and more particularly to a method for repairing a damaged tile wall on the surface of a vertical wall with a stainless steel L-shaped tile repair plate in addition to repairing the inside of a supervisor passage.

  The observer passage provided on the side wall of the tunnel in the long tunnel of the exclusive road for automobiles has a concrete vertical wall facing the roadside belt, and on this vertical wall is made of iron pipe for safety of the observer The handrail is erected. By the way, the side walls of the long tunnel are tiled in order to improve the internal environment of the tunnel as seen from the driver by laying tiles around the tunnel side wall made of concrete. In accordance with the tile interior of the tunnel side wall, when the lane under the railing of the guard's passage is usually laid around the vertical wall made of concrete and the wall of the vertical wall is the concrete surface, It eliminates the dry and dry feeling that it receives and softens the driver's mind inside the tunnel with a tile wall that has been prepared for safe driving.

  By the way, on a motorway in a cold region, since the road surface freezes and becomes slippery, the risk of slipping during traveling is extremely high. Therefore, in order to prevent such road surface freezing, an antifreezing agent, for example, salt such as sodium chloride or calcium chloride is sprayed on the road surface. For this reason, when a car traveling on a road where these antifreeze agents are applied enters the tunnel, the antifreeze salt attached to the tires outside the tunnel is brought into the tunnel as it is, Drop it on the road. Furthermore, the fallen frozen material is spun off with tires, and antifreezing agent is attached to the vertical wall on the side of the roadside belt at the bottom of the tunnel passage side of the tunnel side wall and the iron pipe handrail standing on the vertical wall. Let When spring water in the tunnel is applied to the adhering antifreeze agent, the antifreeze agent is gradually dissolved and permeates from the base plate portion at the base of the handrail into the supervisor passage. When the antifreezing agent penetrates into the supervisor passage in this way, the rebar embedded in the concrete that forms the lower part of the supervisor passage is corroded, and the corroded portion and its surroundings are swollen and deteriorated and damaged, Furthermore, the vertical wall is deteriorated and damaged. In this way, the cross-section of the concrete below the supervisor passage breaks down, extends over the vertical wall, and finally peels off the tile surface spread around the surface of the concrete wall, and the tile falls off.

  On the other hand, if cracks or defects occur on the side wall surface of the tunnel, or if the land of the observer passage is uneven, spring water is generated in the tunnel due to these, and the antifreezing agent is gradually dissolved as described above. It penetrates into the observer passage and destroys the concrete inside, and the tile wall of the vertical wall of the observer passage is also damaged. As a method for repairing these damaged parts, remove the dirt on the surface, apply a primer on it, apply a non-landing conditioner after curing the primer, and paste a fiber sheet such as carbon fiber on the surface Restoration work such as applying a finishing agent is performed. This method requires a high level of skill in the application technique of the unevenness adjusting agent, and the application of the fiber sheet requires a quick operation. Furthermore, it is easy to enclose bubbles in the fiber sheet at the time of sticking, so that the strength of the fiber sheet is reduced and an accident of water leakage is likely to occur again, and it is necessary to perform repair again. These repetitions weakened the strength of the concrete walls of the inner walls of the tunnel and the vertical walls of the guard passage. In this case, the concrete wall body of the leaked part of the inner wall of the tunnel is scraped, and a downflow channel that guides the water leakage is formed inside, and then the ground treatment is performed, and the surface is smoothed with mortar. A method of repairing the inner wall surface of the tunnel by pasting and filling the joints of the tile has been proposed (see, for example, Patent Document 1). However, with this method, after the restoration, water leakage does not flow on the surface of the tile interior that has repaired the wall surface, and the landscape of the tile with the previous tile interior can be restored. For the vertical wall on the roadside belt side, it is necessary to work from the roadside belt side, such as scraping the damaged part of the tile interior, which is the concrete foundation of the tile surface of the vertical wall, that is, the portion of the concrete foundation where the tiles are spread over the surface. is there. For this reason, the road lane closest to the roadside zone must be regulated for safety over a long period of construction, causing a traffic jam for a long period of time and cost.

  Furthermore, as a method of repairing a concrete structure that has been damaged by the antifreeze agent, the deteriorated portion of the concrete structure is removed, a mold is placed at that location, and a grout or mortar containing sulfite is poured into the concrete structure. And a repair method for integrating the formwork with each other has been proposed (see, for example, Patent Document 2). By the way, in this repair method, since the formwork is not removed, it is not necessary to provide a work period for curing the mortar and removing the formwork, but this method is not a method related to the tile wall repair method. Even if it is applied to a place where a tile is stretched on the inner wall surface of the tunnel to form a wall surface of the tile interior, the original tile wall surface or the tile surface of the vertical wall of the observer passage cannot be obtained. Therefore, to restore the landscape of the tile interior, even if mortar is poured into the part deteriorated by this repair method and integrated with the formwork, tiles are further applied to the surface of the integrated formwork on the roadside belt at the site. It is necessary to perform an extra process such as turning around or drawing the color shape of the tile. For this reason, there has been a problem that the construction period requiring traffic regulation in the tunnel has to be extended.

  The problem to be solved by the present invention is that, in order to monitor the condition of the road surface of the traveling lane in the tunnel of the automobile road and the situation of the inner wall of the tunnel, in the observer path provided on the inner wall of the tunnel, Without re-sticking the tiles stretched around the vertical wall surface of the defective part due to the peeling of the tile on the wall surface of the vertical wall under the handrail on the roadside belt side or the damage of the cross section of the concrete in the observer passage It is to provide a method of giving a tile wall landscape that is not different from the original tile wall surface by repairing and repairing the entire surface of the tile of the defective portion at once.

  The part of the tile wall affixed to the surface of the vertical wall, which is the wall of the vertical wall of the concrete below the handrail on the roadside belt side of the observer passage, or the traveling lane outside the tunnel Salts such as sodium chloride and calcium chloride of antifreeze sprayed on the road surface in the winter are brought into the tunnel by the tires of the traveling vehicle, and the salt of antifreeze agent jumps off from the tires to the side of the guard's aisle. The salt-containing water penetrates into the concrete vertical wall of the lower part from the base plate part of the handrail of the observer passage. The salt-containing water that has permeated into the vertical wall of the concrete corrodes the reinforcing bars embedded in the vertical wall of the concrete, and the corroded reinforcing bars and the surrounding portions swell to deteriorate the vertical wall of the concrete. As a result, the cross section of the concrete inside the vertical wall of the observer passage and the separation of the tile wall on the vertical wall surface of the concrete are caused. Therefore, the part where the concrete cross-section fracture or the separation of the tile wall on the surface of the concrete vertical wall is covered with the stainless steel L-shaped tile repair plate, and the covered stainless steel L-shaped tile repair plate is covered. The driver of the vehicle traveling in the driving lane repairs the surface of the vertical wall of the concrete in the observer passage in the backfilled part to the tiled wall surface that has the same color as the original tile wall surface. The landscape of the vertical wall of the guards passage seen from above shall be good. Further, the inventor has intensively researched and found out a method for making the repaired tile wall surface resistant to corrosion by the salt of the antifreeze agent. This is done by placing a stainless steel front tile repair plate with a tile pattern imitating the original tile wall color pattern on the surface of the concrete vertical wall and the base plate part of the handrail of the guard passage.

The made L-shaped tile repair plate is integrated with the concrete roadbed of the observer passage. By this integration method, the section of the vertical wall of the concrete below the handrail on the roadside belt side of the guard's passage is broken and the tiles peeled and damaged are not changed to the original tile pattern. It is a repair method.

  That is, according to the means of the present invention for solving the above-mentioned problems, in the means of claim 1, the passage surface lacking the supervisor passage made of concrete below the base plate of the handrail support column on the roadside belt side of the supervisor passage. And a part of the vertical wall of the missing concrete on the road side belt side of the passage surface, and a part of the tile peeling surface and a part of the damaged tile surface on the surface of the vertical wall. As this repair method, a stainless steel L-shaped tile repair plate made of a front tile pattern repair plate and an upper surface repair frame is brought into contact with the portions requiring repair, and the front surface of the stainless steel L-shaped tile repair plate is further contacted. The surface of the tile pattern repair plate is covered with a panel material, and the panel material and the upper surface repair frame are attached to and supported by the monitoring staff passage surface and the vertical wall of the concrete by a support member having a C-shaped cross section, and then the opening provided in the upper surface repair frame Pour the non-shrinkable mortar into the concrete defect part and the vertical wall defect part on the side of the observer passage from the bottom to the crack part of the concrete roadbed in the observer passage and the tile peeling surface or tile damage surface of the vertical wall surface. , A method of fixing the upper surface repair frame and the front tile pattern repair plate with the non-shrinkable mortar, dismantling the support material after fixing, and further removing the panel material It becomes a repair method according to a stainless steel L-shaped tile repair plate of defects of the defect as well as vertical walls and tile wall surface of the passage surface of the wardens passage of the tunnel side walls Sai.

  In the means of claim 2, a stainless steel L-shaped tile repair plate made of a front tile pattern repair plate and an upper surface repair frame is brought into contact, and the surface of the front tile pattern repair plate is covered with a panel material. In this method, the upper surface repair frame is attached to and supported by a monitoring member passage surface and a vertical wall of concrete by a support member having a C-shaped cross section. In this method, a support material having a C-shaped cross section is vertically contacted to the surface of the panel material covering the surface of the front tile pattern repair plate, and a concrete anchor is driven into the concrete on the inner surface of the lower end portion of the support material, A fixing bolt is coupled to the concrete anchor from the surface of the lower end portion of the support material to support the lower end portion of the panel material.

  EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated below with reference to drawings. As shown in FIG. 1, there is a supervisor passage 4 which is further raised by a concrete roadbed 4a provided on the side wall 1a of a tunnel 1 of a general automobile-only road 1 to increase safety in the event of a car collision. A narrow groove 4b is formed in the tunnel side wall 1a of the monitoring member passage 4 so that water accumulated in the tunnel side wall 1a and the monitoring member passage 4 flows. Furthermore, a vertical wall 5 is provided on the side of the road lane 2 of the concrete roadbed 4 a and the roadside belt 3 that form the supervisor passage 4, and is provided facing the road lane 2. Usually, a tile is stuck to the vertical wall 5 together with the tunnel side wall 1a to form a tile wall surface. A handrail 6 is provided on the vicinity of the vertical wall 5 of the supervisor passage 4, and this handrail 6 is supported by the handrail support 6a. The lower portion of the handrail support 6a is supported by the base plate 6b in the concrete of the supervisor passage 4. It is fixed to the roadbed 4a. At the lower end of the vertical wall 5, there is a circular water channel 3a buried under the road surface. The upper surface of the circular water channel 3a is a part of the roadside belt 3, and rainwater brought into the driving lane is passed through the circular water channel 3a. Flow down.

  As a result of being used over a long period of time after opening, such a tunnel 1 for an automobile road is provided on the road surface of the traveling lane 2 through which the cars in the tunnel pass, the tunnel side wall 1a, and the tunnel side wall 1a. Surveillance passage 4 is damaged. Therefore, the road surface of the traveling lane 2, the tunnel side wall 1a, and the upper tunnel wall are frequently repaired for the safety of the traveling vehicle. By the way, as described above, there is a supervisor who monitors the road surface of the traveling lane 2 and the situation in the tunnel from this position at a position higher than the roadside belt 3 between the roadside belt 3 and the tunnel side wall 1a. A supervisor passage 4 through which is passed is provided. By the way, for a long time, the anti-freezing agent adhering to the tires of the car traveling in the tunnel in the winter season is splashed off inside the concrete roadbed 4a of the observer passage 4 for a long time. The salt infiltrates. That is, the salt content of the antifreezing agent is applied to the concrete roadbed 4a of the roadway 4 of the roadside belt 3 along with water leakage in the tunnel, and the surface of the roadway of the supervisor 6a of the column 6a of the handrail 6 erected on the concrete roadbed 4a. The base plate 6b infiltrates into the concrete roadbed 4a of the lower supervisor passage 4. As shown in FIG. 2, the reinforced concrete rebar 4c that forms the concrete roadbed 4a by the infiltrated antifreeze salt is corroded and swollen to become a swollen portion 4d, and the internal structure of the concrete roadbed 4a is further damaged. It becomes defect 7. When the internal structure of the concrete roadbed 4a is thus damaged, the vertical wall 5 on the side of the concrete roadbed 4a of the supervisor passage 4 formed between the roadside belt 3 is also damaged, and these vertical walls If the tile wall surface 5a is formed on 5, the tile wall surface 5a is also damaged. Therefore, it is necessary to repair the vertical wall 5 having the concrete roadbed 4a of the missing supervisor passage 4 and the tile wall surface 5a on the side of the supervisor passage 4.

  By the way, tiles are stretched over the entire surface of the vertical wall 5 of the concrete roadbed 4a of the supervisor passage 4 and the front surface of the vertical wall 5 is a tile wall surface 5a. Therefore, the portion lacking due to the salt caused by the antifreezing agent described above also extends to the tile wall surface 5a on the front surface of the vertical wall 5, and the tile is cracked or peeled off. Therefore, when repairing the tile wall surface 5a in the front surface of the vertical wall 5 which is the surface of the concrete roadbed 4a of the supervisor passage 4, the travel regulation period of the vehicle traveling in the tunnel is shortened, and the influence is exerted as much as possible. Must be avoided. For this reason, it consists of a front tile pattern repair plate 10 and an upper surface repair frame 11 that can repair a large number of tile surfaces of a certain area at once, eliminating the trouble of replacing tiles one by one when repairing. When repairing using the stainless steel L-shaped tile repair plate 9 and the stainless steel L-shaped tile repair plate 9, the stainless steel L-shaped tile repair plate 9 is supported for fixing until it is fixed with mortar. Repair is performed using a steel support member 14 having a C-shaped cross section. Since the support member 14 has a C-shaped cross section, the rigidity of the support member is improved, and the stainless steel L-shaped tile repair plate 9 and the panel material 12 are firmly supported on the concrete roadbed 4a and the vertical wall 5. it can.

  The size of the stainless steel L-shaped tile repair plate 9 used for this purpose is approximately 900 mm both vertically and horizontally in the front tile pattern repair plate 10 in the front tile pattern repair plate 10, and the vertical right side is The insertion overlap portion 9b having a width of 20 mm is used when repairing two or more stainless steel L-shaped tile repair plates 9 arranged side by side. Further, the lower side of the front tile pattern repair plate 10 is an inclined surface 9c having a vertical width of 20 mm, and further has a vertical mounting surface 9d having a width of 50 mm, and the upper surface of the stainless steel L-shaped tile repair plate 9. Is the upper surface repair frame 11, the horizontal width of the upper surface repair frame 11 is 900 mm which is the same as the lateral width shown in the front view of FIG. 3A, and the depth is as shown in the upper part of the side view of FIG. And 200 mm. The upper surface repair frame 11 is horizontally disposed at a position approximately 50 mm higher than the upper surface of the concrete roadbed 4a, which is the surface of the supervisor passage 4, and the rear end thereof is an inclined surface 9c of 50 mm and comes into contact with the concrete roadbed 4a. Furthermore, it is mounted on the concrete roadbed 4a with a horizontal mounting surface 9d of 40 mm. The reason for positioning the upper surface repair frame 11 at a position 50 mm higher in this way is that when the upper surface repair frame 11 is provided at a position approximately 10 mm higher than the concrete roadbed 4a, from the mortar injection hole 11c of the upper surface repair frame 11 shown in FIG. When the mortar is injected, the mortar is not sufficiently flown into the defect portion 7 at the repair location. However, if the upper surface repair frame 11 is provided at a position that is approximately 50 mm higher, the mortar can flow into the defect portion 7 satisfactorily. In order to prevent the mortar injected from the side end of the upper surface repair frame 11 provided at a position approximately 50 mm higher from flowing out, the portion of the stainless steel L-shaped tile repair plate 9 that is the outermost end of the repair location is the upper surface repair. The side end portion of the frame 11 is bent downward so as to abut on the upper surface of the supervisor passage 4 below 50 mm so as to close the side end portion.

  Repair of the vertical wall of the observer passage provided on the side wall of the tunnel in the tunnel of the automobile road by the stainless steel L-shaped tile repair plate 9 made of the front tile pattern repair plate 10 and the upper surface repair frame 11 described above. The outline of the flow of the method is as follows. Determining the construction position by prior survey → 2. Pretreatment → 3. Marking → 4. Anchor drilling and driving → 5. Installation of stainless steel repair plate, panel material, support material → 6. Filler (mortar) injection → 7. Solidification of filler → 8. Support material dismantling → 9. It will be cleaned up.

  These will be described in more detail. First, a preliminary survey will be conducted before repair work. That is, in order to grasp the situation in the tunnel 1 of the automobile exclusive road, as a preliminary survey, the base plate 6b below the column 6a of the handrail 6 provided for safety on the side of the traveling lane 2 of the supervisor passage 4 is provided. Record the situation of the repaired parts such as the passage surface of the supervisory passage 4 around the road and the wall surface of the vertical wall 5 of the riverside supervisory passage 4 of the traveling route 2, and determine the construction site of the place requiring repair To do. Pre-processing is performed on the repaired part of the determined supervisor passage 4. In this pre-processing, the path surface of the supervisor path 4 around the base plate 6b below the column 6a of the handrail 6 of the handrail 6 of the supervisor path 4 found in the preliminary survey and the vertical length of the guard path 4 of the traveling route 2 are detected. As shown in FIG. 2, a reinforced concrete reinforcing bar 4c that forms a concrete roadbed 4a with respect to peeling or floating of concrete and tiles on the wall due to deterioration due to long-term use on the wall of the wall 5, or by the salt content of the antifreeze agent, If the swollen portion 4d that has been corroded and swollen is peeled off or lifted off, or the swollen portion 4d is scraped off with a hammer or the like, or rust is formed on the reinforcing bar 4c, the rust portion is covered with a wire brush or the like. Perform preparatory repairs such as removal. When this preliminary process is completed, the end of the repair location in the tunnel 1 is determined for this process, and the vertical wall 5 of the supervisor path 4 of that portion is marked with a diamond wheel in a direction perpendicular to the path direction.

  When the end of the repair location is determined, the travel restriction of one lane in the vicinity of the repair lane of the travel lane is restricted, and the equipment is brought to the location where the travel lane is restricted, and the repair work is started. As a start of repair work, a position where a concrete anchor 17 necessary for mounting a support member 14 for supporting a stainless steel L-shaped tile repair plate 9 for repairing the monitoring passage 4 or a panel material 12 placed thereon is driven. Mark on. In this marking, a stainless steel L-shaped tile repair plate is placed at each concrete anchor 17 driving position at the lower part of the vertical wall 5 of the concrete roadbed 4a of the monitoring person passage 4 and the traveling lane 2 below the handrail 6. 9 and the panel material 12 stacked thereon, a leading hole is drilled with a vibration drill at a predetermined position for marking, and then drilled with a hammer drill of a specified thickness. In this case, the drill bit is marked with a vinyl tape so that the perforation depth becomes a predetermined depth, and the depth is confirmed to perforate. In addition, an L-shaped end-stop formwork with a width of a tile pattern to be connected to the tile pattern of the non-repaired area at the end of the repaired area determined above is repaired with a 900 mm-wide stainless steel L-shaped tile. An overlapping portion is provided from the plate 9 and cut out. In order to attach the cut-out L-shaped end portion stop form, markings in the direction of the passage and the vertical direction are made at the lower part of the supervisor passage 4 and the vertical wall 5, and the marking position is punched in the same manner as described above. When the concrete anchor 17 is driven into these drilled portions, an anchor driving rod is always used, and the concrete anchor 17 is driven so as to be perpendicular to the wall surface.

When the concrete anchor 17 is driven in, the stainless steel L-shaped tile is first checked while confirming the unevenness of the concrete surface at the mounting position of the stainless steel L-shaped tile repair plate 9, the panel material 12 and the support material 14. The repair plate 9 is brought into contact with the supervisor passage 4 and its vertical wall 5. That is, the front tile pattern repair plate 10 is brought into contact with the vertical wall 5 and the upper surface repair frame 11 is brought into contact with the supervisor passage 4. Further, the shape of the inclined surface 11a and the horizontal mounting surface 11b on the lower side between the inclined surface 11a and the mounting surface 11b at the end of the upper surface repair frame 11 and the inclined surfaces 11a and the horizontal mounting surfaces 11b on both sides thereof. The column opening cover 11f that has been subjected to is inserted and provided. As shown in FIG. 5, a packing made of a seal rubber 13 is attached to the inclined concrete surface 11a, the attachment surface 11b, and the concrete surface below the support opening cover 11f. The front tile pattern repair plate 10 and the upper surface repair frame 11 of the stainless steel L-shaped tile repair plate 9 and the panel material 12 overlaid on the front tile pattern repair plate 10 are supported from the surface by a support material 14, and FIG. ), The upper part is attached to the concrete anchor 17 by tightening the L-shaped receiving member 16 with a long fixing bolt 15 with a washer 15a, and the lower part is attached to the concrete anchor 17 with a short fixing bolt 15 so that there is no looseness. Secure to. In this case, as described above, since the seal rubber 13 is laid on the concrete surface below the mounting surface 11b, the spring water accumulated in the portion of the supervisor passage 4 does not enter the repaired portion. The stainless steel L-shaped tile repair plate 9 and the adjacent overlapped portions 9b and 11e of the stainless steel L-shaped tile repair plate 9 are fixed with screws (not shown) so that a step is formed between the joints or injected. Prevent mortar from leaking. Further, when the mortar is injected from the mortar injection hole 11c of the upper surface repair frame 11 of the stainless steel L-shaped tile repair plate 9, the front tile pattern repair plate 10 provided on the front surface of the concrete roadbed 4a of the supervisor passage 4 is injected. It is necessary to prevent the mortar from bulging out to the roadside belt 3 side at the front pressure of ² t / m ² . For this reason, the surface of the front tile pattern repair plate 10 is covered with a wooden panel material 12 having a thickness of about 20 mm, and the panel material 12 is supported by the support material 14.

  When the attachment of the support material is completed, the mortar as a filler is mixed and prepared. In this preparation, water weighed in a mortar (trade name: DENKA HIGH PRETUSCON) so that the amount of water is 4.5 kg per 25 kg of mortar is put in a container and sufficiently mixed with a hand mixer. This fully kneaded mortar is poured directly into the mortar injection hole 11c of the upper surface repair frame 11 from a kneaded container. The top end of the injected portion is finished by smoothing by hand twice after the injected mortar settles. Next, since the filled mortar solidifies in about one hour, after confirming the hardness of the mortar filled from the mortar injection hole 11c two hours after the completion of the mortar injection, the fixing bolt 15 is removed and the support material 14 is removed. The panel material 12 of the front surface of the front tile pattern repair board 10 is removed. Thereafter, after the dismantled support material 14 is removed, a stainless steel bolt is again inserted into and fixed to the bolt hole formed by removing the bolt at the time of dismantling in the concrete anchor 17, and water is removed from the bolt hole. Etc. shall not enter.
