Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tunnel lining reinforced lining for the purpose of repair and seismic reinforcement due to aging of concrete for tunnel lining, and more particularly to a method for fixing a resin concrete panel used for the reinforced lining.

  When lining the inner winding reinforcement of a tunnel, an H-shaped steel support bar is installed along the concrete surface of the tunnel cover, and the method of fixing the lining resin concrete panel to this support bar is often adopted. There is. In this method, resin concrete panels are fixed to a plurality of supports installed in the tunnel, the inner surface of the tunnel is covered with the formwork of the filling material for the inner winding reinforcement, and the grout mortar is placed between the panels and the existing concrete surface. The inner surface of the tunnel is lined with the resin control panel and the grout mortar. As a method of fixing the support work and the panel, materials and construction methods have been proposed for the purpose of cost reduction and work efficiency. Therefore, not only the repair and reinforcement of tunnels but also the construction of new tunnels are being considered.

  In Patent Document 1, a resin concrete panel made of the same material as a resin concrete panel is fixed to an H-shaped steel support bar installed on an existing tunnel lining surface, and grout mortar is provided between the rear surface of the panel and the existing tunnel lining surface. The seismic retrofitting method by the reinforcing lining for filling the tunnel is shown. Moreover, in this method, steel plates for reinforcement and reinforcing bars are arranged between the supports to obtain an excellent seismic structure. However, in this construction method, the panel is only temporarily fixed to the support work, and the panel is fixed by fixing the insert metal fittings attached to the back of the panel to the grout mortar which is solidified. . In this inner winding reinforcement lining, since the main fixing is performed by the insert metal fitting, the main fixing cannot be completed unless the filling of the filled grout mortar is completed. However, if a steel material such as a reinforcing steel plate arranged between supporting works is used as the panel fixing steel material to fix the panel, the insert metal fitting is not necessary and the panel is fixed regardless of the solidification of the grout mortar. Therefore, the cost can be reduced.

  However, when installing steel materials such as steel plates between supports, it is difficult to completely fix the steel to the supports. It is usually fixed so that it will rotate when is added. Also, when mounting and fixing a panel in a tunnel, due to the curved surface of the inner surface of the tunnel, a downward force due to the weight of the panel is generated when the panel is mounted on the panel-fixing steel material, causing the panel-fixing steel material to rotate. Will hinder the work. Therefore, there is a need for a method of fixing a resin concrete panel that does not cause such problems.

  An object of the present invention is to provide a resin-reinforced concrete panel that does not hinder the work in a tunnel lining lining using a resin concrete panel, during which the panel-fixing steel material rotates while the panel-fixing steel material is attached and fixed. It is to provide a fixed construction method.

  As a means for solving the above problems, a method of fixing a resin concrete panel in a tunnel inner reinforced lining is a steel support in which respective constituent members having surfaces parallel to and orthogonal to the resin concrete panel are formed. Installed on the existing tunnel lining surface, made of angle steel, one side is a panel fixing side with panel fixing holes, and a fixing material made of rectangular steel plate with fixing bolt holes at both ends. When fixing the attached panel fixing steel material between the steel supports, the panel fixing side is the resin concrete panel side, and both ends of the panel fixing side are respectively parallel constituent members of the steel supporting works. While closely adhering to each other, the fixing materials attached to both ends are fixed to the component members in the orthogonal direction with fixing bolts, respectively, and then the resin concrete panel Characterized by mounting fixed to the panel fixing side.

  In the above-mentioned fixing method, the panel fixing steel material is longer than the interval between the tips of the constituent members having parallel surfaces formed on each steel supporting member, and the panel fixing side of the panel fixing steel member is the steel supporting member. Since it is a construction method in which it is fixed in close contact with a component having parallel surfaces, the panel-fixing steel material does not rotate even when an external force due to the weight of the panel is applied during the mounting and fixing work of the resin concrete panel. Therefore, there is no trouble in the work of attaching the resin concrete panel to the panel fixing steel material.

  In the fixing method described above, the H-shaped steel support bar is used as the steel support bar, and the panel fixing steel material fixed between the support bars is a panel fixing edge of the panel fixing steel material on the flange on the resin concrete panel side. Both ends of each are closely arranged, and the fixing material is fixed to the web by fixing bolts respectively.As the steel support work, a channel steel support work with the back surface of the web located inside the existing tunnel lining is used. A fixed steel material receiving member protruding outward at a right angle to the flange at the mounting location of the panel fixing steel material at the tip of each flange, and the panel fixing steel material fixed during the supporting work is Both ends of the panel fixing side are closely attached to the material, and the fixing material is fixed to the flange with fixing bolts respectively, and one side is the inner surface of the existing tunnel lining for steel support Using the angle steel supporters arranged at right angles to, the panel fixing steel members fixed between the support members are attached to the other side and to the panel fixing steel members at the tops of the angle steel supporting members. It is preferable that both ends of the panel fixing side are closely arranged to the fixed steel material receiving material provided so as to project in the direction opposite to the side, and the fixing material is fixed to the one side by fixing bolts.

  Further, using the channel steel support with the back surface of the web arranged on the side of the existing tunnel lining surface as the steel support, and using angle steel instead of the rectangular steel plate as the fixing material for the panel fixing steel, The fixing bolts are provided on one side of the angle steel, and the other side is provided with a supporting material that projects toward the outside facing the panel fixing side. The support materials provided in the section are closely arranged on the back of the web of the channel steel support, the fixing materials are fixed to the flange of the channel steel support with the fixing bolts respectively, and then the resin concrete panel is fixed to the panel. A form of attaching and fixing to the side is also preferable.

  The fixing method of any of the above forms is provided by projecting on a component member having a surface parallel to the resin concrete panel formed on the steel support, that is, a flange, a web, a side, or a steel support. Since the fixed steel material receiving member and the panel fixing side of the panel fixing steel member or the supporting members provided at these end portions can be closely adhered to each other, the panel can be fixed during the mounting and fixing work of the resin concrete panel. Even if an external force due to the weight of the panel is applied, the panel-fixing steel material does not rotate, and the construction method does not hinder the work.

  By the method for fixing the resin concrete panel as described above, it is possible to perform the tunnel inner winding reinforcement lining by filling grout mortar between the back surface of the resin concrete panel fixed to the panel fixing steel material and the existing tunnel lining surface.

  In addition, in the above method of fixing resin concrete panels, after installing steel supports, before attaching the resin concrete panels to the panel fixing sides and fixing them, each steel support is mutually supported by the support joint material. It is also preferable to stop or arrange reinforcing steel bars in the circumferential direction of the tunnel to form an earthquake-proof reinforcing structure. In this case, the hooking by the supporting material and the reinforcement bar may be arranged after the steel supporting material is installed, before the panel fixing steel material is installed, or after the installation.
