Description

  The present invention relates to a water guiding device for guiding water leaking from a wall surface of a structure such as a tunnel. Specifically, the present invention relates to a water guide panel unit having heat insulation properties to prevent freezing in a water guide channel, or a water guide device formed by connecting a plurality of such water guide panel units.

  In the concrete wall surface of a structure such as a tunnel, the area around the construction joint (concrete seam) is a portion where deterioration such as cracking or peeling of the concrete occurs relatively easily due to infiltration or freezing of groundwater. Groundwater may leak into the tunnel from the walls where such defects such as cracks occur, and in order to treat such leaks, the water leaked from the walls was installed on the concrete wall of the tunnel. There is known a water guide device that guides water to a lower side groove or the like (for example, see Patent Document 1).

  In FIG. 1, sectional drawing of the conventional heat insulation type water guide panel 51 disclosed by patent document 1 is shown. FIG. 2 shows a state in which this water guide panel 51 is installed on the wall surface W of the tunnel. This water guide panel 51 bonds a long (for example, 3 m) water guide plate (inner plate) 52 and a heat insulating plate (outer plate) 53 to each other via a spacing member 54 that is an elastic body having elasticity. It has the structure made. Since the water guide panel 51 is watertightly fixed to the wall surface W through the water stop member 57 at both ends in the width direction, the water guide path 55 is formed between the wall surface W and the water guide panel 51 (specifically, the water guide plate 52). It is formed. Further, a heat insulating space 56 is formed between the water guide plate 52 and the heat insulating plate 53, thereby preventing water in the water guide passage 55 from being frozen and ensuring drainage performance.

Japanese Patent No. 3924287

  The conventional water guide panel 51 described above includes two plates via a spacing member 54 having elasticity so that the inner plate (water guide plate 52) and the outer plate (heat insulating plate 53) have a constant spacing. 52 and 53 are adhered to each other. However, when this water guide panel 51 is installed on an arched wall surface (referred to as an “arch part”) such as a tunnel, a portion that is crushed by the spacing member 54 is generated as shown in an enlarged view in FIG. As a result, there was a concern that the heat insulation performance would be lower than a predetermined value.

  For example, when a water guide panel having a length L = 3 m using polyethylene foam as a spacing member is applied to an arch portion of a tunnel having a width of about 6 m, an outer plate (bending radius ro = 3000 mm) and an inner plate ( (Bending radius ri = 2990 mm), a length difference (displacement) of about 10 mm in the length L direction after construction should occur. However, since there is no such “deviation” in the construction, it is considered that the stretchable spacing member is compressed and deformed to absorb the “deviation”.

  In addition, even if there is some “displacement” between the inner and outer plates after construction, the length will be adjusted by cutting the plates so that no water leaks, but this work is extremely difficult and skillful. There was also a problem in work rationality.

  The present invention has been made in view of such conventional problems, and can ensure sufficient heat insulation performance and drainage performance regardless of the shape of the wall surface of the structure to be installed. It is an object of the present invention to provide a water guide panel unit or a water guide device formed by connecting a plurality of water guide panel units so that the work can be easily performed.

An interval holding member that forms an insulating space layer by being interposed, and the interval holding member is inserted into the inner plate insertion groove into which an end portion of the inner plate is inserted, and the predetermined interval with respect to the inner plate insertion groove It is a water guide panel unit which has an outer plate insertion groove which is formed in parallel and spaced apart and into which an end portion of the outer plate is fitted.

  In the above configuration, the interval holding member is provided at both end portions in the width direction of the inner plate and the outer plate and fixed to the anchor member for fixing them to the wall surface, and the inner plate And an interval holding member for connection provided at both ends in the vertical direction of the outer plate and connectable to other adjacent water guide panel units.

  The fixing interval holding member has a flange portion extending in a width direction from a corner on the side holding the outer plate, and the fixing interval holding member is joined to the anchor member via the flange portion. It is preferable that it is made like this.

  In addition, the connection interval holding member provided at the upper end portion of the inner plate and the outer plate has an upward flange portion extending upward from a corner on the side holding the outer plate, and the inner plate and the outer plate. It is preferable that the connection interval holding member provided at the lower end of the plate has a downward flange portion extending downward from a corner on the side holding the inner plate.

  Moreover, this invention is a water guide apparatus formed by connecting a plurality of water guide panel units having the above-described configuration.

It becomes.

  The water guide device 10 is configured by connecting a plurality of water guide panel units 11 in a row. Here, FIG. 5 is a front view of the water guide panel unit 11. FIG. 6 is an exploded perspective view of the water guide panel unit 11. As shown in these drawings, the water guide panel unit 11 includes an inner plate 12 and an outer plate 13 that are opposed to each other via interval holding members 14, 14, 15U, and 15D provided at the respective upper, lower, left and right ends. The heat insulating space layer 17 defined by the two plates 12, 13 and the spacing members 14, 14, 15U, 15D is provided.

  Here, the inner plate 12 is a so-called water receiving plate that is installed on the side facing the wall surface W and forms the water conduit 16 together with the wall surface W. On the other hand, the outer plate 13 is a so-called heat insulating plate that is installed on the side of the ridge and is opposed to the inner plate 12 at a predetermined interval. The inner plate 12 and the outer plate 13 are formed of a transparent weather resistant hard synthetic resin having the same dimensions. As an example, the inner plate 12 and the outer plate 13 may be transparent vinyl chloride plates having a length of 3 m, a width of 350 mm, and a thickness of 2 mm.

  The spacing members 14, 15 U, 15 D are interposed between the inner plate 12 and the outer plate 13. In the present embodiment, the spacing members 14, 15U, 15D are fixed spacing retaining members 14 provided at both ends in the width direction (left and right in the present embodiment) of the inner plate 12 and the outer plate 13, and the inner plate 12 and the outer plate. And 13 interval holding members 15U and 15D for connection provided at respective ends in the longitudinal direction (up and down in the present embodiment).

On the other hand, the connection interval holding members 15U and 15D are provided so as to be connectable to other adjacent water guide panel units 11.

  The fixing interval holding member 14 is a rod-like member having substantially the same length as the inner plate 12 and the outer plate 13 and is formed of, for example, a weather-resistant synthetic resin such as vinyl chloride. An inner plate insertion groove 141 into which the end portion in the width direction of the inner plate 12 is inserted and an outer plate insertion groove 142 into which the end portion in the width direction of the outer plate 13 is inserted into the inner side surface of the fixing interval holding member 14. , And are continuously formed in parallel at a predetermined interval. According to the fixing interval holding member 14 of one embodiment, the interval between the inner plate insertion groove 141 and the outer plate insertion groove 142 is 10 mm.

  The fitting state of the inner plate insertion groove 141 and the inner plate 12 of the fixing interval holding member 14 is such that the inner plate 12 is slidable within the inner plate insertion groove 141, and silicone (sealing material) described later is used. As long as watertightness and airtightness can be secured in the case of injecting, either a clearance fit or an interference fit may be used. Further, the fitting state between the outer plate insertion groove 142 and the outer plate 13 can be either a clearance fit or an interference fit as long as the outer plate 13 is slidable within the outer plate insertion groove 142 and airtightness can be secured.

  For example, as shown in FIG. 7, between the inner plate insertion groove 141 and the outer plate insertion groove 142, a cavity portion 145 closed by the bridge portion 144 is formed together with the bridge portion 144. Although not shown in the figure, for example, a signal line for transmitting the output of a temperature sensor or a dew condensation sensor, a communication line such as a network, or a heater wiring may be passed through the hollow portion 145.

  A flange portion 143 extending in the width direction is integrally formed on the outer side surface of the fixing interval holding member 14 from the corner on the side that holds the outer plate 13 (the lower side in FIGS. 6 and 7). The flange portion 143 has a plurality of holes 143a, 143a,. Anchor bolts 30 for fixing the water guide panel unit 11 to the tunnel wall through the anchor member 20 are inserted into the respective holes 143a. That is, the fixing interval holding member 14 is joined to the anchor member 20 via the flange portion 143 extending in the left and right direction.

  The connecting interval holding members 15U and 15D are different in length from the above-described fixing interval holding member 14 and can employ a common member. The lengths of the connecting spacing holding members 15U and 15D are substantially the same as the widths of the inner plate 12 and the outer plate 13. An inner plate insertion groove 151 into which the upper and lower end portions of the inner plate 12 are fitted and an outer plate insertion groove into which the upper and lower end portions of the outer plate 13 are fitted into the inner side surfaces of the connecting spacing holding members 15U and 15D. 152 are continuously formed in parallel at a predetermined interval.

  The fitting state of the inner plate insertion groove 151 and the inner plate 12 of the connecting spacing members 15U and 15D is such that the inner plate 12 can slide in the inner plate insertion groove 151, and watertightness and airtightness are ensured. If possible, either a clearance fit or an interference fit may be used. Similarly, the fitting state of the outer plate insertion groove 152 and the outer plate 13 is either a clearance fit or an interference fit if the outer plate 13 can slide in the outer plate insertion groove 152 and can secure airtightness. But you can.

  In particular, as shown in FIG. 6, a connecting interval holding member 15 </ b> U provided at the upper ends (upstream, left in FIG. 6) of the inner plate 12 and the outer plate 13, and the lower ends of the inner plate 12 and the outer plate 13 The position of the flange portion 153 is opposite to the connection spacing member 15D provided on the downstream side (the right side in FIG. 6). That is, the connecting interval holding member 15U provided at the upper end portion has a flange portion 153 extending upward from the outer (lower side in FIG. 6) corner that holds the outer plate 13. On the other hand, the connecting interval holding member 15D provided at the lower end portion has a flange portion 153 extending downward from an inner corner (upper side in FIG. 6) for holding the inner plate.

  The procedure for constructing the water leakage prevention work using the water guide device 10 according to the present embodiment will be described below.

(Import / Preparation)
Members necessary for installation of the water guide device 10 are carried into the site. A mark indicating the mounting position of the anchor bolt 30 is provided in advance on the surface of the anchor member 20.

(Assembly of water guide panel unit)
After transparent silicone is uniformly injected into the inner plate insertion groove 141 of the fixing spacing member 14, the end of the inner plate 12 is inserted into the inner plate insertion groove 141 as shown in FIG. Further, the end portion of the outer plate 13 is inserted into the outer plate insertion groove 142 of the fixing interval holding member 14. Silicone does not necessarily have to be inserted into the outer plate insertion groove 142. The fixing spacing members 14 and 14 at both ends in the width direction of the inner plate 12 and the outer plate 13 are symmetrical.
When the water guide panel unit 11 is installed in the arch portion, only the upper connection spacing member 15U is attached to the upper ends of the inner plate 12 and the outer plate 13 as shown in FIG. The connecting spacing holding member 15U is attached by uniformly injecting silicone into the inner plate insertion groove 151 and the outer plate insertion groove 152, and inserting the upper ends of the inner plate 12 and the outer plate 13 into the grooves 151 and 152, respectively. Do.
In addition, after installing the water guide panel unit 11 in an arch part, it is preferable to attach the space | interval holding | maintenance member 15D for a lower side after cut | disconnecting the extra length part of the protruded outer plate | board 13.

(Assembly of anchor member)
The anchor member 20 includes a case body 24 and a water stop member 21 embedded in the case body 24, as shown in FIG. In the case body 24, a flange insertion groove 23 is continuously formed in the longitudinal direction.
Adhesive seals 22 are attached to the left and right anchor members 20. And after inject | pouring silicone into the flange part insertion groove | channel 23, each flange part 143 of the space | interval holding member 14 for fixation on either side is inserted in the groove | channel 23 (FIG. 11).
A hole is drilled at a position marked on the anchor member 20, and a vinyl chloride pipe cut to a predetermined length is inserted into the hole (not shown).

(Installation of water guide panel unit)
The water guide panel unit 11 is vertically applied to the leaked wall surface W, and a pilot hole is formed in the wall surface W with a hammer drill from the anchor bolt mounting hole of the anchor member 20. Then, the water guide panel unit 11 is firmly fixed to the concrete wall surface W by driving the anchor bolt 30 into the prepared hole and tightening with the nut 31 (FIGS. 12 and 13).

When the water guide panel unit 11 is installed at the arch portion of the tunnel, the outer plate 13 protrudes from the inner plate 12 due to the difference in bending radius. Therefore, the protruding extra length of the outer plate 13 is cut to adjust the length. Then, the lower connecting interval holding member 15D is attached to the lower ends of the inner plate 12 and the outer plate 13 having the same length.
Thereby, between the inner plate 12 and the outer plate 13, the heat insulation space layer 17 sealed with the space | interval holding members 14, 14, 15U, and 15D is formed.

(Connection of water guide panel unit)
By installing the plurality of water guide panel units 11 so as to be vertically connected from the water leak location of the tunnel, the water guide device 10 that guides the water leak downward can be formed. As described above, in the water guide panel unit 11, the connecting interval holding member 15U provided at the upper end portion has the upward flange portion 153 extending upward from the corner on the side holding the outer plate 13, and provided at the lower end portion. The connecting spacing holding member 15 </ b> D has a downward flange portion 153 extending downward from a corner on the side holding the inner plate 12. Therefore, as shown in FIGS. 14 and 15, the upstream water guide panel unit 11U and the downstream water guide panel unit 11D are connected to each other by connecting space holding members 15U and 15D that are opposite to each other. It can be effectively prevented.

  According to the water guide panel unit 11 of this embodiment, there are the following advantageous effects.

  The water guide panel unit 11 has a heat insulating space layer 17 in which an inner plate 12 and an outer plate 13 are defined by spacing members 14, 14, 15 U and 15 D. Therefore, even when installed in a tunnel in a cold region, for example, the heat insulation space layer 17 can prevent water in the water conduit 16 from being frozen, and the drainage performance can be sufficiently maintained.

  When the water guide panel unit 11 is installed along the curved surface of the arch portion of the tunnel, the inner plate 12 and the outer plate 13 are inserted into the inner plate insertion groove 141 and the outer plate when the panel is bent. Slide in the groove 142. In addition, the upper and lower surplus portions of the outer plate 13 can be absorbed by the outer plate insertion grooves 152 and 152 of the coupling interval holding members 15U and 15D. Therefore, the water guide panel unit 11 can be arbitrarily curved while keeping the distance between the inner plate 12 and the outer plate 13 (the thickness of the heat insulating space layer 17) constant. Therefore, even if it is installed on the wall surface of any shape, the thickness of the heat insulation space layer 17 is kept constant, and the heat insulation performance does not deteriorate.

  Moreover, since the internal stress is not generated in the inner plate 12 and the outer plate 13 when the water guide panel unit 11 is bent, the strength of the plate is also maintained. Therefore, for example, even if a stepping stone collides with the outer plate 13, the outer plate 13 is not easily broken.

  Moreover, since it can be assembled and installed easily, the work at the site can be improved as compared with the prior art.

  Further, the upstream water guide panel unit 11U and the downstream water guide panel unit 11D can be connected by connecting spacing holding members 15U and 15D in opposite directions. In particular, as shown in FIG. 15, the flange portion 153 of the upstream water guide panel unit 11 </ b> U covers the connecting portion of the spacing members 15 </ b> U and 15 </ b> D on the water guide passage 16 side, and water leaks from this connecting portion. Can be effectively prevented.

  As shown in FIGS. 14 and 15, a convex portion 156 is provided on the main body of the connecting spacing holding members 15U and 15D, and a concave portion 157 is provided on the flange portion 153. At the time of connection, the convex portion 156 and the concave portion 157 are provided. The structure which mutually fits may be sufficient. According to this configuration, the waterproofness of the connecting portions of the spacing members 15U and 15D can be further effectively improved, and workability when connecting the water guide panel units 11U and 11D can be improved.
