Abstract

<P>PROBLEM TO BE SOLVED: To provide a tunnel leaking water preventive plate which prevents the dripping and freezing of leaking water in a tunnel, has a section of a small size to hardly come in contact with a traveling large vehicle, to hardly be broken and dropped even if coming in contact with a vehicle, and can be installed in a tunnel having a small inner space. <P>SOLUTION: A resin panel 12 of a multilayer structure includes a plurality of spaced resin plates 14, and a plurality of resin partitions 16 which are fixed to the resin plates 14 at a proper angle, and ends of the resin panel 12 are closed by a sealing means 28 such as a tape made of an acrylic resin, etc. The resin panel 12 is fixed to a tunnel inner wall 30 via a fixing metal fixture 18 bent in a vehicle traveling direction to form the tunnel leaking water preventive plate. Space in the section of the resin panel 12 provides a heat insulating effect and the size of the section is small, so that the leaking water preventive plate hardly comes in contact with a traveling large vehicle and can be installed in a tunnel having a small inner space. Even if the leaking water preventive plate comes in contact with a large vehicle, the deformation of the fixing metal fixture 18 and the space divided and sealed in the section of the resin panel 12 alleviate impacts caused by the contact to hardly allow the leaking water preventive plate to be broken and dropped. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a tunnel leakage prevention plate applied to the surface water conveyance method among existing tunnel leakage measures. More specifically, the present invention relates to a tunnel water leakage waterproof plate that is broken and hardly peeled off when contacting a large vehicle.

  In the existing tunnel where water leakage occurs, in order to prevent obstacles to vehicle traffic in the tunnel due to dripping of water into the tunnel or freezing of water leakage, prevention of water leakage for the tunnel that constitutes a wall surface floating away from the inner wall of the tunnel A board is installed. Conventional tunnel leakage prevention plates are known in Japanese Patent Application Laid-Open No. 11-182196 and Japanese Patent Publication No. 4-60199. The water leakage prevention plate described in JP-A-11-182196 is formed by forming a single heat insulation layer between a heat insulation plate made of foamed polyethylene or the like stretched on a tunnel inner wall via a waterproof sheet, and the heat insulation plate. It is provided with a surface layer board stretched. Japanese Patent Publication No. 4-60199 discloses a panel formed by sandwiching a heat insulating material between a metal plate such as aluminum.

  The conventional tunnel leakage prevention plate has a heat insulation effect such as foamed polyethylene and a single layer of air to prevent the leakage of water, so that the cross-sectional dimension is large and the vehicle in the tunnel can pass after installation. There is a problem that the portion becomes small and comes into contact when a large vehicle passes, and is easily broken and peeled off. In addition, there is a problem that it cannot be installed at a location where water leakage occurs in a tunnel with a small cross section in the tunnel.

  Accordingly, the present invention can prevent leakage of water into the tunnel and freezing of water leakage, has a small cross-sectional size, is difficult to contact when a large vehicle is passing, and is difficult to break and peel even when the large vehicle is contacted when passing. The purpose of the present invention is to provide a tunnel leakage prevention plate that can be installed in a tunnel having a small cross section in the tunnel.

  The tunnel water leakage prevention plate according to claim 1 is formed by fixing a resin panel having a multi-layer structure to a fixing bracket fixed to a tunnel inner wall by an appropriate fixing means such as an anchor bolt, and floating away from the tunnel inner wall. A water leakage prevention plate for a tunnel that constitutes the wall surface of the state, and the resin panel having a multilayer structure is composed of a plurality of resin plates with intervals and a plurality of resin partition walls fixed at an appropriate angle, The cross section of the resin panel is divided into multiple spaces, the end of the resin panel is closed by appropriate means such as aluminum tape, and the divided space in the cross section of the resin panel is sealed and fixed The metal fitting is a water leakage preventing plate for a tunnel characterized in that the inner wall fixing portion of the tunnel and the resin panel fixing portion are connected in a shape bent in the vehicle traveling direction at an appropriate angle.

  According to the present invention, since a heat insulation effect is obtained by a plurality of divided and sealed spaces in the cross section of the resin panel, the cross-sectional dimension is small, so that it is difficult to contact when a large vehicle passes, and a conventional water leakage prevention plate Can be installed even in a tunnel with a small cross section in the tunnel that could not be installed.

  Furthermore, even when a large vehicle comes into contact, the member of the fixing metal that is bent in the vehicle traveling direction and the divided and sealed space in the cross section of the resin panel are less likely to break and peel off because the impact is reduced. A tunnel leakage prevention plate is obtained.

  Next, a tunnel water leakage prevention plate according to a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a state in which a tunnel leakage prevention plate according to a preferred embodiment of the present invention is attached to a tunnel inner wall. FIG. 2 is a cross-sectional view of a portion where the tunnel leakage prevention plate is fixed to the inner wall of the tunnel.

  The multi-layered resin panel 12 is divided into a plurality of spaces by a plurality of resin plates 14 having an interval and a plurality of resin partition walls 16 fixed thereto at an appropriate angle.

  The end of the multi-layered resin panel 12 is closed by a sealing means 28. Therefore, the space divided into a plurality of cross sections of the resin panel 12 is sealed, and the heat insulation effect is obtained by the sealed space. Therefore, the heat insulation used in the conventional tunnel leakage prevention plate is used. The same thermal insulation effect can be obtained with a cross-sectional dimension smaller than that of the material or foamed polyethylene.

  The sealing means 28 seals and closes the end portion of the multi-layered resin panel 12 with a tape made of acrylic or the like, and at the edge of the water leakage prevention plate, a resin member having a U-shaped cross section In the connection part of the resin panels 12 adjacent to each other on the left and right, the connection part made of a resin having a H-shaped cross section and the filler 26 are used to prevent damage to the tape.

  The resin-made panel 12 having a multilayer structure is fixed with bolts 22 to a fixing plate 24 bent according to the shape of the inner wall of the tunnel. Further, the fixing bracket 18 fixed to the inner wall of the tunnel by the fixing means 20 and the fixing plate 24 fixing the above-mentioned sealed multi-layered resin panel 12 are connected by bolts 22, so that the multi-layered structure is formed. The resin panel 12 is fixed to a predetermined position of the tunnel inner wall in a state of being lifted away from the tunnel inner wall.

  The fixing bracket 18 is a bracket in which a tunnel inner wall fixing portion and a resin panel fixing portion are connected by a member bent in an appropriate angle in the vehicle traveling direction, and a large vehicle passes through the multi-layered resin panel 12. When contact is sometimes made, it is difficult to peel off because the bent member is deformed to reduce the impact.

  When a large vehicle comes in contact with the vehicle, it is difficult to break and peel off because the impact can be mitigated by a space that is divided into a plurality of sections of the resin panel 12 and sealed.

  It is the perspective view which showed the state in which the tunnel water leakage prevention board which concerns on preferable embodiment of this invention was attached in the tunnel.   It is sectional drawing of a tunnel water leakage prevention board fixing | fixed part.
