Description

  The present invention relates to a repair agent injection apparatus for injecting a repair agent used for repairing a crack generated in a concrete structure or the like into a crack of concrete.

  Conventionally, as a repair agent for repairing a crack in a concrete structure, a method of injecting the repair agent into the crack using the restoring force of an elastic sheet has been used.

  However, with the conventional repair agent injection device, it is not possible to easily measure the introduction amount of the repair agent, the progress of the injection of the repair agent, whether or not the injection of the repair agent is completed, the injection of the repair agent I couldn't check the remaining amount easily.

Furthermore, since the external height of the repair injection device is high, there may be a problem in construction such as hooking during bonding.

The inside becomes a hollow portion 5b and is fixed on the elastic sheet 4 and inserted into the spring 7 so that the outer peripheral surface is visible. Ri consists of a cylindrical gauge 5 which is provided with a.

  As shown in FIGS. 1 to 3, the donut-shaped cover 2 has a circular hole 2 f formed in the upper left portion when viewed from the front, so that the inside of the cover 2 can be seen. Further, when the cover 2 is viewed from the front side, that is, on the opposite side of the hole 2f, a protruding portion 2b having a hollow 2j is formed on the upper right side. Due to the presence of the hole 2f formed in the cover 2, the elastic sheet 4 expanded by the repair agent is deformed and expanded from the hole 2f, thereby preventing overfilling.

  The upper portion of the gauge 5 is inserted into the hollow 2j of the protruding portion 2b, and the upper end 2c of the protruding portion 2b and the upper end of the gauge 5 are substantially the same when no repair agent is injected into the repair agent injection device 1. In position.

  The injection part 2d has a hollow inside, and the injection hole 2g corresponding to the upper part in the injection part 2d becomes smaller in diameter as it goes downward, and the hollow 2h corresponding to the lower part from the center of the injection part 2d has a diameter. Is constant.

  In the hollow 2h of the injection part 2d, a columnar backflow preventing member 6 and a spring 7a, each having a convex part 6a with a small diameter at the top and a hollow 6b inside, are inserted. The spring 7a is located below the backflow preventing member 6 and pushes the backflow preventing member 6 up to the top of the hollow 2h.
