ンクリートの一部が剥離したり強度低下を来たす
ので、接着剤や固化剤などの薬液を亀裂内部に注
入しなければならない。<Prior Art> As is well known, thin cracks occur on the surface of concrete buildings and structures over a long period of time. If these cracks are left untreated, they will gradually expand, causing parts of the concrete to peel off or weaken, so chemicals such as adhesives and solidifying agents must be injected into the cracks.

まで充満しないので、低圧で長時間を要して注入
しなければならない。 In order to inject the chemical solution into the above-mentioned crack, the substrates d with the cylindrical portions c standing upright are attached to the surface of the wall b of the concrete structure where the crack a has occurred at appropriate intervals along the crack a, and the substrates d , d is closed with a sealing material e, and a chemical injection device is attached to the cylindrical portion c, and this injection device pumps the chemical liquid from the cylindrical portion c into the crack a. In this case, even if the chemical solution is injected at high pressure and in a short time, it will not fill the microscopic voids in the crack, so it must be injected at low pressure and over a long period of time.

填している。 Conventional injection devices have a rubber bag, which is inflated by supplying a medicinal liquid into the bag.The spout of the bag is tightly connected to the cylindrical part c, and the contraction force of the bag is used to inject the inside of the bag. Injected gradually. When the bag no longer contracts, it is assumed that the chemical solution has been injected, and the substrate d is removed from the wall surface b, the chemical solution is cured, and then the sealing material e is peeled off and the opening of the crack is filled with mortar or the like. .

効果を期待することができない。<Problems to be solved by the invention> However, in the conventional repair device described above, the member for storing the chemical solution is a rubber bag or an opaque tank, so it is unclear how much chemical solution is injected into the crack. It is. Therefore, the inside of the crack may not be filled with the chemical solution, and in this case, a sufficient repair effect cannot be expected.

その量を外部から読み取ることができる。 In this state, the hollow needle 13 provided at the tip of the drug solution supply tube 12 is inserted into the first valve 2 as shown in FIG. When the hollow needle 13 is inserted, as shown in FIG. A discharge port 13' opens in the supply space 4. Therefore, when a drug solution is supplied from the drug solution supply tube 12 into the supply space 4 through the hollow needle 13, the supply space 4 is filled with the drug solution, and the drug solution overflowing from the supply space 4 passes through the opening 6. and flows into the air chamber 5. And air chamber 5
When the amount of chemical liquid in the air chamber 5 increases and its level rises, the air in the air chamber 5 becomes compressed. In this case, since the valve membrane 8 is in close contact with the outer peripheral surface of the hollow needle 13, the medicinal solution does not pass between the hollow needle 13 and the valve membrane 8 and leak to the outside. Moreover, when the chemical liquid flows into the air chamber 5, the amount can be read from the outside by a scale S provided in the air chamber 5.

に沿つて外部に漏れることがない。 When the entire repair device is pressed toward the cylindrical portion c in this state, the hollow needle 11 is inserted into the second valve 3, and the tip opening 11' of the hollow needle 11 opens into the supply space 4, as shown in FIG. The air chamber 5 and the cylindrical portion c communicate with each other. In this state, the compressed air in the air chamber 5 pressurizes the chemical solution, so the air chamber 5
The chemical solution inside passes through the hollow needle 11 of the cylinder part c from the supply space 4 and is injected into the crack a. In this case, the broken part of the valve membrane 8' of the second valve 3, which has broken and curved inward, and the inner circumferential surface of the liner 10 are in close contact with the outer circumferential surface of the hollow needle 11. No leakage to the outside along the surface.
また、亀裂ａ内に注入された薬液の量は、空気
