Description

  The present invention relates to a water channel structure suitable for repairing and rehabilitating an existing concrete water channel.

  Existing concrete waterways have the problem that the concrete walls are deteriorated and damaged due to water, sand flow, freezing and thawing, salt damage, and acid corrosion.

  In order to cope with such problems, a plurality of lining plates made of a thermoplastic resin having a plurality of parallel anchor projections with widened tips on a wall surface to be repaired on a concrete water channel are to be repaired. It is connected to the wall in the flow direction while forming a gap with the anchor projection facing the wall surface, and connected in the width direction with a joint member. It is filled with a backfill agent between the wall surface to be repaired and the lining plate and solidified. The connecting portion between the lining plates connected in the flow-down direction is such that the upstream lining plate is disposed in the upper layer and the downstream lining plate is disposed in the lower layer, and the anchor protrusion of the upper lining plate is removed. In addition, there has been proposed a water channel structure in which a finished inner surface of a lower lining plate is joined to a surface on the repair target wall side (Patent Document 1).

Also, although not a water channel structure, in a concrete pipe in which a plurality of plastic lining plates divided in the circumferential direction of the concrete pipe along the inner wall surface of the concrete pipe body are attached via a filler, A connecting and fixing member is fixed on the inner wall surface side of the concrete pipe body, and the wall surface of the connecting and fixing member viewed from the center side of the concrete pipe body is fully extended along the pipe axis direction of the concrete pipe. A connecting groove having a shape is formed, and the lining plate is connected and fixed to the connecting groove with a joining piece projecting along an adjacent split edge of the lining plate and having a wide head portion fitted. A concrete pipe is known (Patent Document 2).

  However, since the joint member is not fixed to the wall surface to be repaired in the water channel structure of Patent Document 1, when filling the backfilling agent between the lining plate and the wall surface to be repaired, the lining plate is used as a support. There is a problem that it is necessary to position and support from the inside of the water channel, and this positioning work is not easy. In addition, when connecting the lining plates in the flow direction, it is necessary to cut off part of the anchor projections.

  On the other hand, in the case of adopting the lining structure of Patent Document 2, the positioning of the lining plate is easy because the connecting and fixing member is fixed to the inner wall surface, but the opening width of the connecting groove of the connecting and fixing member is narrow. The problem is that the work of connecting the connecting pieces of the plates into the connecting grooves is not easy, and the water is likely to enter and accumulate in the connecting grooves that are spread out, so that the connecting fixing members are destroyed when the accumulated water freezes. was there.

  The present invention has been made under the circumstances described above, and the problem to be solved is that the panel (lining plate) is positioned and fixed, the connection in the width direction and the length direction of the panel is easy, and the repair of the water channel To provide a water channel structure that can efficiently cover and repair a wall to be processed, and that water does not enter the groove-shaped connecting material that connects the panels in the width direction, and there is no risk of the groove-shaped connecting material being deformed or damaged by freezing. It is in.

In order to solve the above problems, a water channel structure according to the present invention is:
A rectangular panel in which an anchor protrudes from the back surface, and a protruding line having a retaining portion from both side ends protrudes toward the back side;
An opening is formed on both side plates, and an engaging portion protrudes inward from the upper end of both side plates, and a groove-shaped connecting material in which a fixed piece protrudes from one end or both sides from the lower end,
With joint material,
A plurality of the groove-shaped connecting materials are arranged in parallel at a pitch interval larger than the width dimension of the panel by a substantially width dimension of the joint material on the wall surface of the concrete water channel to be repaired. The fixing piece is fixed to the wall surface with a stopper, and a plurality of the panels are arranged side by side, and the protrusions adjacent to each other are fitted into the groove connecting members, and the retaining portions of the protrusions are engaged with the groove connecting members. The panel is connected to the groove-shaped connecting member while being connected to each other in the width direction, and a wall covering is formed by sandwiching the joint material between these panels. It is characterized by being filled with a backfilling agent and solidified.

  The water channel structure of the present invention, as in claim 2, wherein the wall covering is formed by aligning the length direction of the channel-shaped connecting material and the panel with the length direction of the water channel, As shown in FIG. 7, the wall covering is roughly divided into a case where the length of the groove-shaped connecting member and the panel is made to coincide with the direction perpendicular to the length direction of the water channel.

  In the former case, that is, when the wall covering is formed by aligning the length direction of the channel-shaped connecting member and the panel with the length of the water channel, the wall covering is formed as a water channel as in claim 3. Forming the bottom wall upper surface and both side wall inner surfaces to be repaired, and the panel at the both ends of the wall covering covering the bottom wall upper surface of the water channel and the bottom panel of the wall covering covering the inner wall at both sides of the water channel, It is desirable to connect through a corner member and to solidify by filling a backfilling agent between the wall surface covering body and the corner member, and the bottom wall upper surface and both side wall inner surfaces of the water channel.

  In the case of the former, as described in claim 4, each wall surface covering is formed by arranging a plurality of wall surface coverings in the length direction of the water channel on the bottom wall upper surface and both side wall inner surfaces of the water channel. The panel at the both ends of the body and the panel at the lower end of each wall covering covering the inner walls of both sides of the water channel are connected via the corner members, and the wall coverings arranged in the length direction of the water channel are connected to each other. The end portions of the panels butted against each other are connected by a connecting material, and a backfilling agent is filled between the wall surface covering body, the corner member, and the connecting material, and the bottom wall upper surface and both side wall inner surfaces of the water channel. It is also desirable to solidify.

  And, as in the fifth aspect, the corner member is formed by projecting a convex strip having a retaining portion from both side ends thereof downward and laterally outward, and a convex strip at one side end of the corner member and this The protrusions of the panel adjacent to the corner member and the protrusions of the other end of the corner member and the protrusions of the panel adjacent to the corner member are fitted into the groove-shaped connecting material, and the retaining portion of the protrusion is connected to the groove-shaped connecting material. It is desirable that the corner member and the panel adjacent to the corner member are connected to each other by engaging with the engaging portion of the first member, and the support member has support convex portions on both side surfaces as the connecting member. Using the projections with small grooves, insert the panel anchor ends into the small groove and connect the panel ends to each other by supporting the panel ends with the support projections. It is desirable to do.

  On the other hand, in the latter case, that is, when the wall surface covering is formed by aligning the length direction of the groove-shaped connecting material and the panel with the direction orthogonal to the length direction of the water channel, as in claim 8 The wall covering is formed on the upper surface of the bottom wall of the water channel and on the inner surfaces of both side walls, the both ends of the panel of the wall surface covering covering the upper surface of the bottom wall of the water channel, and the panel of the wall surface covering covering the inner surfaces of the both walls of the water channel. It is desirable that the lower end portions are connected by a corner connecting material, and a backfilling agent is filled and solidified between the wall covering body and the corner connecting material, and the bottom wall upper surface and both side wall inner surfaces of the water channel.

  And, as in the ninth aspect, the corner connecting material has a vertical side surface and a horizontal upper surface, and is provided with support convex portions on the vertical side surface and horizontal upper surface, respectively, and a small groove is formed on these support convex portions. The end of the anchor of the wall covering panel covering the upper surface of the bottom wall of the water channel, and the lower end of the anchor of the wall covering panel covering the inner surface of the side wall of the water channel, the vertical side surface of the corner connecting material and the horizontal upper surface The edge of the wall covering panel covering the bottom wall upper surface and the lower end of the wall covering panel covering the side wall inner surface are inserted into the small groove of the support convex portion provided on the vertical surface of the corner connecting material. It is desirable to support and connect to a support convex portion provided on the horizontal upper surface.

  Like the water channel structure of the present invention, the fixing piece of the groove-shaped connecting material is fixed to the wall surface to be repaired of the concrete water channel with a stopper, and the protruding strips of adjacent panels are fitted into the groove-shaped connecting material, Attach the protrusions of the ridges to the engaging parts at the upper ends of both side plates of the grooved connecting material, connect the panels in the width direction, and attach them to the grooved connecting material. When the covering body is formed, the panel of the wall surface covering body is positioned and fixed at an interval equal to the height of the groove-shaped connecting member from the wall surface. Therefore, as in Patent Document 1, the panel is placed inside the water channel with another support body. Therefore, the backfilling agent can be filled between the wall covering and the wall surface without any support and positioning, and the workability is improved accordingly. And since the backfilling agent filled between the panel and the wall surface penetrates and fills the inside of the groove-shaped connecting material from the openings of both side plates of the groove-shaped connecting material, both sides of the groove-shaped connecting material The backfilling agent is not continuously divided at the opening of the groove-shaped connecting material, and the strength of the backfilling agent-filled layer is improved. Further, when the groove-shaped connecting material is filled with the backfilling agent, water does not enter and accumulate in the groove-shaped connecting material, so that the concern that the groove-shaped connecting material is deformed or broken due to freezing is also eliminated. Further, when the joint material is sandwiched between the panels, the gap between the panels is filled with the joint material, and leakage of the backfilling agent from the gap is prevented, and the projection of the panel is grooved by the joint material. When the back cover is filled with the back-filling agent, the protruding portion of the connecting strip is pressed against the engaging portion at the upper end of the both side plates of the connecting material and securely engages the engaging portion. There is no need to worry about the panel being detached from the channel connecting material. Moreover, when fitting the protrusions of the panel into the groove-shaped connecting material, there is a margin corresponding to the approximate width dimension of the joint material in the open upper end width of the groove-shaped connecting material (interval between the engaging portions at the upper ends of both side plates). Therefore, the fitting operation is easy.

  The water channel structure according to claims 2 to 6 is a wall surface covering body that covers the upper surface of the bottom wall of the water channel by matching the length direction of the channel connecting member and the panel of the wall surface covering body with the length direction of the water channel. The panel at the both ends of the wall and the panel at the lower end of the wall covering that covers the inner surface of both walls are connected via a corner member, and are further arranged in the length direction of the water channel on the upper surface of the bottom wall and the inner surface of the both walls. By connecting the end portions of the panels of the wall coverings that face each other with a connecting material, the upper surface of the bottom wall and the inner surfaces of both side walls of the concrete water channel can be efficiently covered and repaired.

  On the other hand, the water channel structure according to claims 7 to 9 is configured such that the lengthwise direction of the channel-shaped connecting member and the panel of the wall covering body coincides with the direction orthogonal to the length direction of the water channel, and covers the upper surface of the bottom wall of the water channel. By connecting the both ends of the wall covering panel to the lower end of the wall covering panel covering the inner surfaces of both side walls with a corner connecting material, the upper surface of the bottom wall and the inner surfaces of the both side walls of the concrete water channel to be repaired are connected. Efficient covering and repairing is possible.

The engaging portion 1b engages with a retaining portion 2c formed on a protruding strip 2b of the panel 1 to be described later, and fixes the panel 1 so as not to be detached from the groove-shaped connecting material 1.

  The side plates 1a and 1a of the groove-shaped connecting member 1 are formed with rectangular openings 1c and 1c over the entire length of the connecting member at regular intervals, and both side plates are used to form the openings 1c and 1c. The parts cut out from the lower end of both side plates 1a, 1a are projected and protruded as both fixed pieces 1d, 1d. The fixing pieces 1d and 1d are formed with stopper insertion holes 1e and 1e through which a stopper 4 such as an anchor bolt described later is inserted.

  The opening 1c serves to introduce and fill the backfilling agent 7 to be described later into the groove-shaped connecting material 1, so that the backfilling agent 7 can be filled into the groove-shaped connecting material 1 without a gap. It is preferable to form the entire length of the connecting material at intervals of about 20 cm. Moreover, you may project the fixing piece of another member from the lower end of the both-sides board 1a, but if the part cut out in order to form the opening part 1c as mentioned above is expand | deployed and utilized as the fixing piece 1d, another member will be provided. This is economically advantageous because it is not necessary to project the fixed piece.

  The groove-shaped connecting material 1 is very preferable because it is obtained by processing a plated steel sheet having a thickness of about 1 mm because it can be easily rusted and has sufficient strength. However, the material is not particularly limited, and aluminum Of course, other metal or FRP may be used. Moreover, although the said groove-shaped connection material 1 has provided the fixed piece 1d in the both sides from the lower end of the both-sides plates 1a and 1a, you may make it provide only in one side.

  The panel 2, which is another component of the wall covering, is a rectangular long molded product molded from a thermoplastic resin such as polyvinyl chloride, and its surface (upper surface) as shown in FIG. Is laminated with a weather-resistant surface layer 2a made of a highly weather-resistant resin such as AAS, whereby the weather resistance of the panel 2 is enhanced. And the protruding ridges 2b and 2b are projected from the both ends of this panel 2 toward the back side, and it engages with the engaging parts 1b and 1b of the said channel-shaped connection material 1 on the inner surface side of these protruding ridges. The retaining portions 2c and 2c to be joined are formed. Further, on both side ends of the upper surface of the panel 2, recessed step portions 2d and 2d for receiving a head portion 3a of a joint material 3 to be described later are formed. Further, on the back surface of the panel 2, a lower end portion 2f is formed. A plurality (two in the illustrated example) of the anchors 2e having inverted T-shaped cross-sections protruding on both sides are provided in parallel with each other over the entire length of the panel.

  The joint material 3 which is still another component of the wall covering is sandwiched between the panels, and has a width dimension w as shown in FIG. A strip-shaped head portion 3a that fits into the concave step portion 2d is formed, and a bulging portion 3b that engages with the lower end of the ridge 2b of the panel 2 is formed at the lower end of the joint material. Yes. And in order to improve sealing performance, the sealing material layers 3c and 3c are formed on both side surfaces of the joint material 3, and a plurality of deformable fin portions 3d are also formed on the sealing material layers 3c and 3c. .

  The material of the joint material 3 and the sealing material layer 3c is not particularly limited, but the joint material 3 is preferably made of a resin (including rubber) such as AAS having excellent weather resistance, and the sealing material layer 3c It is preferable to produce with soft resin (including rubbers) such as soft vinyl chloride resin.

  A wall covering covering the bottom wall upper surface 101 of the existing water channel 100 to be repaired is formed using the above-described groove-shaped connecting member 1, panel 2, and joint material 3 in the following manner. That is, the length direction of the groove-shaped connecting material 1 and the length direction of the water channel 100 are made to coincide with the bottom wall upper surface 101 so that the plurality of groove-shaped connecting materials 1 are substantially wider than the width dimension of the panel 2. As shown in FIG. 3, the fixing piece 1d is fixed by a stopper 4 such as an anchor bolt which is driven from the stopper insertion hole 1e of the fixing piece 1d of the groove-shaped connecting member 1 as shown in FIG. Is fixed to the bottom wall upper surface 101, and the channel-shaped connecting member 1 is attached to the bottom wall upper surface 101. Next, the length direction of the panel 2 and the length direction of the water channel 100 are made to coincide with each other, and a plurality of panels 2 are arranged, and as shown in FIG. 3, the protruding strips 2b and 2b of the adjacent panels 2 and 2 are grooved. By fitting into the shape connecting material 1, the retaining portions 2 c, 2 c of the ridges 2 b, 2 b are engaged with the engaging portions 1 b, 1 b at the upper ends of both side plates of the groove shape connecting material 1 from below, and adjacent panels 2 The two are connected in the width direction so as not to be detached from the groove-shaped connecting material 1. Then, the joint material 3 is sandwiched between these panels, and the sealing performance is improved by filling the gap, and the head portion 3a of the joint material is fitted into the recessed steps 2d and 2d of the adjacent panels 2 and 2, The bottom to be repaired by engaging the bulging portion 3b at the lower end of the joint material with the lower ends of the ridges 2b and 2b of the adjacent panels 2 and 2 so that the joint portion is a flat surface and the joint material 3 does not come off. A wall covering covering the wall upper surface 101 is formed.

  The wall covering covering both side wall inner surfaces 102, 102 of the water channel 100 to be repaired is formed in exactly the same manner as the wall covering described above. The panels 2 and 2 at both ends of the wall covering covering the bottom wall upper surface 101 of the water channel and the panels 2 and 2 at the lower end of the wall covering covering both the inner walls 102 and 102 are shown in FIGS. As shown in FIG. 2, they are connected via corner members 5 and 5.

  As shown in FIG. 7, the corner member 5 has a shape in which the panel 2 is bent at a right angle at the center in the width direction. In other words, the corner member 5 is made of a bent resin plate having an L-shaped cross-section with a weather-resistant surface layer 5a, and a protrusion 5b is formed at one side end (right end in the example) of the corner member. The protrusion 5b is protruded downward, and the protrusion 5b is protruded laterally outward at the other end (upper end in the illustrated example). And these protrusions 5b and 5b are formed with retaining portions 5c and 5c. Further, concave step portions 5d and 5d for receiving the head portions 3a of the joint material 3 are formed on the surfaces of both side ends of the corner member 5, and the tip portions are formed on both sides on the back surface of the corner member 5. Two anchors 5e and 5e having inverted T-shaped cross-sections projecting downward are projected downward and laterally outward, respectively.

  The corner member 5 is connected to the panel 2 at the side end of the wall covering covering the bottom wall upper surface 101 and the panel 2 at the lower end of the wall covering covering the inner wall 102 in the following manner. That is, as shown in FIG. 7 (b), the protruding strip 5b (the protruding strip on the right end in the example) on one side end of the corner member 5 and the protruding strip 2b (bottom wall upper surface 101) of the panel 2 adjacent thereto. The projection 2b of the panel 2 at the side end of the wall covering that covers the wall is fitted into one channel-shaped connecting member 1, and the projection 5b at the other end of the corner member 5 (in the example shown, the projection at the upper end). ) And the ridge 2b of the panel 2 adjacent thereto (the ridge 2b of the panel 2 at the lower end of the wall covering covering the side wall inner surface 102) is fitted into the other channel-shaped connecting material 1, By engaging the retaining portions 5c, 2c with the engaging portions 1b, 1b of the groove-shaped connecting member 1, and further sandwiching the joint material 3 between the protruding strips 2b of the panel 2 and the protruding strips 5b of the corner member 5. The corner member 5 and both the panels 2 and 2 are connected to each other so as not to be detached from the groove-shaped connecting material 1.

  A plurality of wall surface coverings are formed side by side in the length direction of the water channel 100 on the bottom wall upper surface 101 and both side wall inner surfaces 102, 102 of the water channel 100, and the wall surface coverings arranged in the length direction of the water channel 100 are arranged. The ends of the panels 2 and 2 that are abutted to each other are connected by a connecting material 6.

  The connecting member 6 has a length equal to the width dimension of the panel 2 as shown in FIG. 9, and as shown in FIGS. 8 and 9, support convex portions 6a and 6a are provided on both side surfaces thereof. In the supporting convex portions 6a and 6a, longitudinal small grooves 6b for inserting the ends of the anchors 2e of the panel 2 are spaced apart from the anchors 2e with a mutual interval equal to the mutual interval of the anchors 2e. The same number (two in the illustrated example) is formed. The vertical dimension of the small groove 6b is substantially the same as the height dimension of the anchor 2e except for the lower end 2f protruding on both sides of the anchor 2e. When the end of the anchor 2e is inserted into the small groove 6b, the anchor 2e The lower end 2f is adapted to engage with the lower surfaces of the support convex portions 6a on both sides of the small groove 6b. Further, notches 6c and 6c are formed at both ends of the support convex portion 6a so as to escape so that the convex strips 2b and 2b on both sides of the panel do not hit when the panels are connected.

  The ends of the panels 2 and 2 butted together in the length direction of the water channel are inserted into the small grooves 6b and 6b of the connecting member 6 by inserting the ends of the anchors 2e and 2e of the panels 2 and 2 from both sides. The end portions of the panels 2 and 2 are overlapped with the support convex portions 6a and 6a provided on both side surfaces of the connecting material 6 so that the upper surface of the connecting material 6 and the upper surfaces of both the panels 2 and 2 are flush with each other. It is done by supporting. When connected in this manner, as shown in FIGS. 9B and 9C, the lower end 2f of the anchor 2e is engaged with the lower surfaces of the support protrusions 6a on both sides of the small groove 6b, and the support protrusions 6a are in the panel. 2 and the lower end 2f of the anchor 2e are sandwiched from above and below, so there is no concern that the connecting member 6 will drop off from the ends of the panels 2 and 2. In addition, since the upper surface of the connecting member 6 and the upper surfaces of the panels 2 and 2 are flush with each other, there is no fear that a solid matter is caught or the flow of water is hindered.

  In addition, what is necessary is just to perform the connection of the edge parts of the corner member 5 which face | matched mutually using the connection material of the shape which bent the said connection material 6 at right angle in the longitudinal direction intermediate part.

  1 and 2, a plurality of wall coverings are formed side by side in the length direction of the water channel 100 on the bottom wall upper surface 101 and both side wall inner surfaces 102 and 102 of the water channel 100 as described above. The above-mentioned corner members 5 are formed by combining the panels 2 and 2 at both ends of each wall covering covering the wall upper surface 101 and the panels 2 and 2 at the lower ends of each wall covering covering both inner walls 102 and 102 of the water channel. , 5 are connected to each other, and the end portions of the panels 2 and 2 that face each other in the wall coverings arranged in the length direction of the water channel are connected to each other by the connecting member 6 described above, and these wall coverings are connected to each other. Further, the back-filling agent 7 is filled and solidified between the corner member 5 and the connecting member 6 and the bottom wall upper surface 101 and both side wall inner surfaces 102 and 102 of the water channel. As the backfilling material 7, concrete, cement milk, grout agent, mortar, resin mortar, or the like is used.

  Like this water channel structure, the fixing piece 1d of the groove-shaped connecting member 1 is fixed to the bottom wall upper surface 101 and both side wall inner surfaces 102, 102 of the existing water channel 100 made of concrete with the stoppers 4 and adjacent to each other. The projections 2b and 2b of the panels 2 and 2 to be fitted are fitted into the groove-shaped connecting material 1, and the retaining portions 2c and 2c of the protrusions 2b and 2b are engaged with the engaging portions 1b at the upper ends of both side plates of the groove-shaped connecting material 1, The panel 2 is connected to the groove-shaped connecting member 1 while being connected to each other in the width direction, and the joint material 3 is sandwiched between the panels 2 and 2 to form a wall covering, and the corner member 5 is engaged. When the wall covering body is connected with the connecting member 6, the panel 2 and the corner member 5 of the wall covering member are spaced from the bottom wall upper surface 101 and the both side wall inner surfaces 102, 102 at a distance equal to the height of the groove-shaped connecting member 1. Since the panel is positioned and fixed, the panel 2 is watered by other support means. The back-filling agent 7 can be filled between the wall surface covering body, the corner member 5 and the connecting member 6, and the bottom wall upper surface 101 and the both side wall inner surfaces 102 and 102 without being supported and positioned from the inside. As a result, the workability is improved accordingly.

  When the backfilling agent 7 is filled in this way, the anchor 2e on the back surface of the panel 2 is buried in the backfilling agent 7, so that the panel 2 is stuck to the inner surface of the backfilling agent 7 filling layer so as not to be peeled off. And since this backfilling agent 7 penetrates into the inside of the groove-shaped connecting material 1 from the openings 1 c, 1 c of the both side plates of the groove-shaped connecting material 1 and is filled, The filling agent 7 is not continuously divided at the opening 1c of the channel-shaped connecting material 1, and the strength of the backfilling agent 7 filling layer is improved. In addition, when the groove-shaped connecting material 1 is filled with the backfilling agent 7, since the water does not enter and accumulate in the groove-shaped connecting material 1, the concern that the groove-shaped connecting material 1 is deformed or damaged by freezing is also eliminated. Is done.

  Furthermore, when the joint material 3 is sandwiched between the panels 2 and 2, the gap between the panels is filled with the joint material 3 to improve the sealing performance, and the backfilling agent 7 can be prevented from leaking from the gap. By the joint material 3, the protrusion 2 b of the panel 2 is pressed against the engaging portion 1 b at the upper end of both side plates of the groove-shaped connecting member 1, so that the retaining portion 2 c of the protrusion 2 b is reliably engaged with the engaging portion 1 b. When filling the backfilling agent 7, the engagement between the retaining portion 2c and the engaging portion 1b is released, and there is no fear that the panel 2 is detached from the groove-shaped connecting material 1. Further, when the protrusion 2b of the panel 2 is fitted into the groove-shaped connecting material 1, the joint material 3 has a width equal to the opening width of the upper end of the groove-shaped connecting material 1 (interval between the engaging portions 1b, 1b at the upper ends of both side plates). Since there is a margin for the approximate width dimension, the fitting operation is easy.

  In addition, the operation of forming the wall covering is relatively simple, and the operation of connecting the panel 2 of the wall covering with the corner member 5 and the connecting member 6 is further simple. Can be efficiently coated and repaired.

  The corner member that connects the panel 2 at the side of the wall covering covering the bottom wall upper surface 101 of the water channel 100 and the panel 2 at the lower end of the wall covering covering the inner wall 102 is limited to the corner member 5 described above. The thing of various shapes can be used instead of a thing. FIG. 10 is a cross-sectional view showing another example of such a corner member. The corner member 50 excludes a horizontal plate portion 50b at one end and a vertical plate portion 50c at the other end (upper end). The portion is formed on an inclined plate portion 50a inclined at 45 degrees, and an anchor 50d is projected from the center of the back surface of the inclined plate portion 50a at a right angle. Since other configurations are the same as those of the corner member 5 described above, the same reference numerals are given to the same portions in FIG.

  Similarly to the corner member 5 described above, such a corner member 50 is also provided with one ridge 5b (one on the right side in the figure) and the ridge 2b of the panel 2 adjacent thereto in one groove shape. While fitting into the connecting material 1, the protruding strip 5 b at the other side end (the protruding strip at the upper end in the example) and the protruding strip 2 b of the panel 2 adjacent thereto are fitted into the other groove-shaped connecting member 1, The protrusions 5c, 2c of the ridges are engaged with the engagement parts 1b, 1b of the channel-shaped connecting member 1, and the joint material 3 is further interposed between the ridges 2b of the panel 2 and the ridges 5b of the corner member 50. By being sandwiched between the panels, the panels 2 and 2 are connected so as not to be detached from the groove-shaped connecting material 1.

  Instead of the corner member 50 and the corner member 5 described above, the panel 2 may be used as a corner member inclined at 45 degrees. Even if the panel 2 is also used as a corner member in this way, there is a margin in the open upper end width of the groove-shaped connecting member 1, so that the protruding strips 2 b and 2 b at both ends are fitted into the groove-shaped connecting member 1 in an oblique direction. It is possible to connect with adjacent panels.

  FIG. 11 is a partial perspective view of a water channel structure according to another embodiment of the present invention, and FIG. 12A shows a corner connecting material used in the water channel structure and a vertical panel connected thereto. FIG. 12B is a perspective view of the corner connecting member and the lateral panel connected to the corner connecting member as viewed from the upper oblique side. FIG. 13A is a perspective view of the corner connecting member. The perspective view which shows another example, (b) of FIG. 13 is the front view.

  The water channel structure shown in FIG. 11 has a wall surface covering in which the length direction of the channel-shaped connecting member 1 and the panel 2 constituting the wall surface covering body coincides with the direction perpendicular to the length direction of the existing concrete water channel 100. The body 100 covers and repairs the bottom wall upper surface 101 and the left and right side wall inner surfaces 102, 102 of the water channel 100 to be repaired.

  That is, this passage structure uses the groove-shaped connecting material 1, the panel 2, and the joint material 3 as described above, and the channel-shaped connecting material 1 is attached to the bottom wall upper surface 101 and both side wall inner surfaces 102, 102 in the longitudinal direction. While arranging and fixing in parallel with the same pitch interval as described above while matching the length direction of the water channel 100, and arranging a plurality of panels 2 so that the length direction of the water channel 100 and the length direction of the water channel 100 are aligned, A panel of wall coverings that are connected in the same manner so as not to be detached from the respective groove-shaped connecting members 1 and sandwich the joint material 3 between the panels to form a wall covering and cover the bottom wall upper surface 101 of the water channel. 2 and the lower end portion of the panel 2 of the wall covering covering both side wall inner surfaces 102, 102 of the water channel are connected by a corner connecting member 8, and the wall covering and corner connecting member 8 are connected to the water channel. Bottom wall upper surface 101 and both side wall inner surfaces 102, Between 02, in which solidified upon filling the backfill material 7.

  As shown in FIG. 12, the corner connecting member 8 has a length equal to the width dimension of the panel 2, and has a vertical side surface 8b and a horizontal upper surface 8c on both sides of the inner inclined surface 8a. Support convex portions 8d and 8d are provided on the side surface 8b and the horizontal upper surface 8c, respectively. Further, in these support convex portions 8d and 8d, small grooves 8e and 8e into which the end portions of the anchors 2e of the panel 2 are inserted have the same number as that of the anchors 2e with the same number as that of the anchors 2e. Then two) are formed. The vertical dimension of the small groove 8e formed on the support convex part 8d protruding from the vertical side surface 8b and the horizontal dimension of the small groove 8e formed on the support convex part 8d protruding from the horizontal upper surface 8c both protrude on both sides of the anchor 2e. The height of the anchor 2e excluding the lower end 2f is almost the same as that of the anchor 2e. When the end of the anchor 2e is inserted into the small groove 8e, the lower end 2f of the anchor 2e is engaged with the support convex portions 8d on both sides of the small groove 8e. It comes to match. In addition, notches 8f and 8f are formed at both ends of the support convex portion 8d so as to escape so that the convex strips 2b and 2b on both sides of the panel do not hit when the panels are connected.

  The connection between the both ends of the panel 2 of the wall covering covering the bottom wall upper surface 101 of the water channel and the lower end of the panel 2 of the wall covering covering the both side wall inner surfaces 102, 102 of the water channel is performed by the corner connecting material 8. The ends of the anchors 2e, 2e of both panels 2, 2 are inserted into the small grooves 8e, 8e of the support convex portions 8d, 8d provided on the vertical side surface 8b and the horizontal upper surface 8c of the both sides from above and from both sides. The end portions of the panels 2 and 2 are supported by overlapping the upper and side surfaces of the support convex portions 8d and 8d, respectively. When connected in this manner, the support protrusion 6a of the corner connecting member 8 is sandwiched between the end of the panel 2 and the lower end 2f of the anchor 2e, so that the corner connecting member 8 becomes the end of the panels 2 and 2. There are no worries about dropping out. Further, since the inner slope 8a of the corner connecting member 8 and the surfaces of the panels 2 and 2 are continuous, there is no fear that a solid matter is caught or the flow of water is hindered.

  In addition to the above-described effects, such a water channel structure can form a wall covering with four types of component parts including the groove-shaped connecting material 1, the panel 2, the joint material 3, and the corner connecting material 8. There is also an effect that the types of the constituent parts of the wall covering body can be reduced as compared with the water channel structure of the embodiment.

  The corner connecting material is not limited to the corner connecting material 8 described above, and various shapes other than the above can be used. FIG. 13 is a cross-sectional view showing another example of such a corner connecting member. This corner connecting member 80 includes support protrusions 8d on the vertical side surface 8b at the lower end of the swash plate portion 80a and the horizontal upper surface 8c at the upper end. 8d is provided, and small grooves 8e and 8e for inserting the end portions of the anchor 2e of the panel 2 are formed in the support convex portions 8d and 8d, and the protrusions 2b and 2d of the panel 2 are formed at both ends of the support convex portions 8d and 8d. Cutout portions 8f and 8f for escaping 2b are formed, and an anchor 80b is projected from the back surface of the swash plate portion 80a.

  Similarly to the corner connecting member 8 described above, the corner connecting member 80 also has the end portions of the anchors 2e and 2e of both panels 2 and 2 inside the small grooves 8e and 8e of the support convex portions 8d and 8d. Are inserted from above and the end portions of both panels 2 and 2 are supported by the support convex portions 8d and 8d, respectively, so that both the panels 2 and 2 can be easily connected. Moreover, since the anchor 80b on the back surface of the swash plate portion 0a is buried in the backfilling agent, the corner connecting member 80 can be attached so as not to be detached.

  In addition, when the water channel 100 is bent, as shown in FIG. 16, using the fact that there is a margin in the upper end open width of the groove-shaped connecting member 1 (the distance between the engaging portions 1b and 1b at the upper ends of both side plates). In addition, it is preferable to form a wall covering corresponding to the bending of the water channel 100 by separating the panel 2 and the joint material 3 as much as possible on one end side and closely contacting each other on the other end side.

  By the way, like the water channel structure shown in FIG. 11, the length direction of the channel-shaped connecting member 1 and the panel 2 constituting the wall covering is matched with the direction orthogonal to the length direction of the concrete water channel 100, For covering and repairing the bottom wall upper surface 101 and the side wall inner surface 102 of the water channel 100 to be repaired with the wall covering, the groove-shaped connecting material 1 and the panel 2 cut to a length corresponding to the width dimension of the water channel 100 are used. Thus, a wall surface covering body having a width dimension matching the bottom wall upper surface 101 of the water channel 100 can be formed. On the other hand, like the water channel structure shown in FIGS. 1 and 2, the length direction of the channel-shaped connecting member 1 and the panel 2 constituting the wall covering is made to coincide with the length direction of the concrete water channel 100. In the case of covering and repairing the bottom wall upper surface 101 to be repaired of the water channel 100 with the wall surface covering, the width of the wall covering may not match the width of the water channel 100. It is difficult to adjust the width dimension.

  Therefore, when it becomes necessary to adjust the width dimension of the wall covering as described above, it is preferable to adjust using the panel 20 shown in FIG. That is, this panel 20 is the same as the panel 2 described above, and is further provided with a retaining portion that also serves as an anchor between the ridges 2b, 2b on both side ends and the anchors 2, 2, and between the anchors 2, 2. A plurality of (three) auxiliary ridges 20b with 2c are projected in parallel from the back surface over the entire length of the panel.

  Such a panel 20 is cut along the auxiliary projections 20b so as to have a width dimension necessary for adjustment, and as shown in FIG. 15, the corner member 5 on one side (the right corner member 5 in FIG. 15) The auxiliary ridges 20b at the cut ends and the ridges 5b of the corner members 5 are fitted into the groove-shaped connecting member 1 and the joint material 3 is further sandwiched between the cut panel 20 The corner members 5 are connected to each other so as not to be detached from the groove-shaped connecting material 1. As a result, a wall covering corresponding to the width dimension from the left corner member 5 to the right corner member 5 is formed.

  In FIG. 15, the above-described panel 20 is used as a panel for forming the wall covering, but the panel 2 is used as a panel other than the panel 20 on the right end that is cut for width adjustment. Needless to say.

  Moreover, although the example of width adjustment was shown in FIG. 15, like the water channel structure shown in FIG. 11, the length direction of the groove-shaped coupling material 1 and the panel 2 which comprise a wall surface covering body is made into a concrete water channel. In the case of covering and repairing the bottom wall upper surface 101 and the side wall inner surface 102 to be repaired with a wall surface covering body in a direction orthogonal to the length direction of 100, the same method as the width adjustment shown in FIG. Needless to say, the length of the waterway can be adjusted.

  In the above, the water channel structure of the present invention has been described by taking as an example the case where the bottom wall upper surface 101 and the left and right side wall inner surfaces 102, 102 of an existing concrete water channel 100 having a concave cross-sectional shape are covered and repaired with a wall surface covering. However, the present invention is of course also applied to the case where the bottom wall upper surface and the left and right side wall inner surfaces of an existing concrete water channel having a square cylindrical cross section are covered and repaired with a wall covering.
