Description

  The present invention repairs a wall in the tunnel, which is located on the side of the tunnel when the wall rising from the road surface is damaged due to aging or other reasons, or when there is a risk of such damage. The present invention relates to a method for repairing a wall surface for setting up a supervisor passage.

  All wall surfaces in the tunnel, including the wall surface that raises the surveillance passage from the road surface, are in a poor environment due to exhaust gases of various automobiles passing through the tunnel, and tend to deteriorate rapidly. As the deterioration of each part constituting the wall surface, the tiles constituting the wall surface may be peeled off. As a result, if the tile or its fragments fall on the road surface, these may cause serious traffic. May cause an accident. Therefore, in order to prevent such an accident, it is necessary to repair the deteriorated wall surface promptly.

  Conventionally, repairing a wall surface in such a tunnel, particularly a tile wall surface facing a road surface where a supervisor passage is set up, removes and removes a deteriorated portion of the wall surface to be repaired by applying an impact, etc. Forming a formwork with a certain interval on the front surface of the wall surface, placing mortar between them to form a new mortar ground layer on the front surface of the wall surface, and further, individual tiles on the front surface of the mortar ground layer, Or it has been performed by attaching a tile panel formed by attaching a plurality of tiles to a substrate.

  In the above-mentioned formwork, anchor bolts are fixed to a wall surface to be repaired, and further, a support member is fixed on a curb or a road surface in contact with the lowermost part of the wall surface to be repaired, and then the anchor bolt and the support member are attached. It was intended to be temporarily fixed using. The support member cannot be fixed on the curb or road surface because it is not permitted to drive anchor bolts or the like into the curb or the like. Therefore, the support member is fixed to the curbstone or the like using an adhesive or the like, but it is necessary to use an adhesive having a high adhesive strength in order to securely fix the support member to the curbstone or the like. When removing the above-mentioned formwork, of course, it is necessary to remove the support member, but at that time, there is a problem that the adhesive remains on the curbstone or the like.

  There is no other known method for repairing the wall surface that raises the observer passage in the tunnel from the road surface. Patent Document 1 that proposes a tunnel lining construction method is a prior art document that is considered to be a reference for this repair method.

  This tunnel lining construction method is a precast concrete slab that is also used as a formwork and is divided into a plurality of pieces in the circumferential direction so as to face the ground surface of the tunnel, and the bottom is the weir plate part on the surface facing the ground surface A precast concrete plate having an open concrete filling portion that is closed, and the precast concrete plate is fixed at a predetermined position facing the natural ground surface via a support arm, and then the natural ground surface And rapidly filling concrete with good fluidity between the precast concrete plate and the precast concrete plate.

  The idea that the precast concrete slab is also used as a formwork in this tunnel lining construction method can be applied to the wall surface repairing method for raising the above-mentioned supervisor passage from the road surface. That is, the technical idea of the precast concrete plate used as the mold is applied to the tile panel in the repair method of the prior art, and the tile panel is used as the mold. If it does in this way, the tile panel which is also used as a formwork at a predetermined interval is arranged on the front surface of the wall surface to be repaired, and this is fixed to the state via the support arm, and then the tile panel and the wall surface to be repaired By injecting rapid-curing mortar with good fluidity between the two, the wall surface can be repaired quickly without the need for subsequent removal of the formwork or tile mounting.

  However, in Patent Document 1, there is no explanation about the support arm, and its configuration is completely unknown. Therefore, there is a problem similar to the problem related to fixing of the support member in the repair method of the prior art, and this problem cannot be solved at all. That is, it is the same as that there is no description about the attachment of the tile panel, and it is difficult to find an appropriate means as the attachment method from Patent Document 1.
