It is possible, and the physical properties such as the viscosity and curing rate of the repair or base adjusting material can be adjusted. The tip of the nozzle portion 4 may be open, but it is preferably sealed. When the tip of the nozzle portion 4 is sealed, the inner bag body 3 is torn to generate a repair or base adjustment material at the construction site, and then the tip of the nozzle portion 4 is cut with scissors or the like to open the nozzle portion 4. do.
The repair or base adjustment material container 1 may further have a lid portion 5 that covers the nozzle portion 4. The lid portion 5 prevents the contents in the repair or base adjustment material container from leaking or drying and hardening. However, when the tip of the nozzle portion 4 is sealed, the lid portion 5 is not always necessary. The material constituting the lid portion 5 is not limited, and examples thereof include nylon, polyolefins such as polyethylene and polypropylene, and polypropylene is preferable.

It is sealed on the outside of the body 3 and the remaining mixing material is sealed in each of the three inner bag bodies.

The method for manufacturing the repair or base adjusting material container is not limited, and for example, it can be manufactured as follows.
First, the nozzle portion 4, the lid portion 5, and the screw member 16 are manufactured by injection molding of a thermoplastic resin or the like. A screw member 16 is attached to one open end of the thermoplastic resin tube with an adhesive or the like to prepare an outer bag body 2 in which one end 8 is open. Two quadrangular thermoplastic resin films 14 and 15 having the same shape and dimensions are laminated, heat-sealed on three sides 10, and an inner bag body 3 having a quadrangular shape with only one side 9 open is formed. To make. Instead of the two quadrangular thermoplastic resin films, one open end of the tubular thermoplastic resin film is heat-sealed to prepare an inner bag having the shape of a quadrangular view in a plan view in which only one side is open. May be good. One of the mixing materials for repair or base adjustment material is put in the inner bag body 3, and the inner bag body 3 containing the mixing material is stored in the outer bag body 2 in which one end 8 is opened, and the inner bag body 3 is stored. The open side of the bag and the open end of the outer bag are overlapped so that they match, the overlapped part is heat-sealed, and the open side of the inner bag and the open end of the outer bag are simultaneously placed. Heat seal. The outer bag body 2 is filled with the other mixing material of the repair or base adjusting material from the opening of the screw member 16 (that is, the polymer cement material is enclosed inside the outer bag body 2 and outside the inner bag body 3). (If the repair or base adjustment material consists of three or more types of mixing materials, prepare multiple inner bags, put the mixing materials in each of the multiple inner bags, and put the mixing materials. The plurality of inner bag bodies are housed in the outer bag body having one end open, and the open sides of the plurality of inner bag bodies are overlapped so that the open ends of the outer bag body match. The overlapped part is heat-sealed, the open side of the inner bag body and the open end of the outer bag body are heat-sealed at the same time, and then the outer bag body is repaired or the base adjustment material is repaired from the opening of the screw member. Fill the rest of the mixing material.). After that, the nozzle portion 4 is attached, and finally, the lid portion 5 is attached.

It is preferable that the repair or base adjusting material container 1 is in an inflated state by sufficiently enclosing air in the outer bag body during transportation. By doing so, the risk of the inner bag body 3 breaking during transportation is reduced.
When the repair or base adjustment material container 1 is used at the construction site, after removing a part or all of the air from the outer bag body 2, force is applied to the inner bag body 3 from the outside of the outer bag body 2 to apply force to the outer bag body 2. The inner bag body 3 is broken inside the body 2. By removing a part or all of the air, the inner bag body 3 can be broken without damaging the outer bag body 2.
After breaking the inner bag body 3, the contents are well kneaded from the outside of the outer bag body 2 by hand to sufficiently mix the plurality of mixing materials.
If the properties of the repair or base adjustment material obtained by mixing (for example, viscosity, curing speed, etc.) are not in an appropriate state, remove the nozzle portion 4 attached by the screw 17 and add an additive as appropriate. Then, the repair or base adjustment material is adjusted to an appropriate state.
When filling a cracked portion of concrete, for example, with a repair or base adjustment material, the lid portion 5 of the repair or base adjustment material container 1 is removed, the tip of the nozzle portion 4 is cut, and a force is applied to the outer bag body 2 from the outside. , The repair or base adjustment material is extruded from the nozzle portion 4, and the repaired part is filled with the repair or base adjustment material.
When the repair or base adjustment material remains in the repair or base adjustment material container 1 after filling with the repair or base adjustment material, the remaining repair or base is formed by attaching the lid portion 5 to the nozzle portion 4 and sealing it. It is possible to prevent the adjusting material from drying and hardening.

The repair or ground conditioner container of the present invention has the following features.
(A) Can be installed simply by rubbing and extruding by hand. When the repair or base adjustment material is a crack repair material made of polymer cement material, the crack repair material made of a general polymer cement material is a cup of two materials, an admixture and powder. What was kneaded with a stirring rod inside is put back into a container for construction with a nozzle for construction, but in the repair or base adjustment material container of the present invention, the inner bag is compressed and kneaded by hand for kneading. Since it is constructed, it can be easily constructed without any hassle.
(B) Fixing the inner bag to the outer bag To prevent the inner bag from moving to the discharge bag and preventing the compound from being discharged when the inner bag is torn and kneaded by hand, the inner bag is the outer bag (for example). , Fixed to the bottom of the outer bag).
(C) Chemicals can be added before construction Since the nozzle portion can be removed and opened, it is possible to post-add a curing retarder or water reducing agent before construction to improve workability.
(D) A lid on the tip of the nozzle By attaching a lid (for example, a twisted lid) to the tip of the nozzle, it is possible to prevent the tip of the nozzle from being hardened and unable to be discharged.

In the repair or ground conditioner container of the present invention, at least two kinds of mixing materials can be separated and sealed, and the mixing materials can be mixed at a construction site related to construction, etc. It can be suitably used as a container for producing a repair or base adjustment material and applying it to a repair or base adjustment location.
