Compared with the prior art, after the device is inserted into a grouting opening, the grouting gun is inserted into the device and is propped against the device by force, so that the spring in the device is pressed to the bottom, the inner sleeve 1 can be extended out of the outer sleeve 2, and grouting can be performed by using a grouting machine. When grouting is finished, the grouting gun is pulled out, and the inner sleeve 1 automatically rebounds into the outer sleeve 2 under the action of the spring and is fixed. At the moment, the grouting opening is completely blocked, and the backflow phenomenon cannot occur. The invention solves the problem of slurry backflow when the grouting gun is pulled out after grouting is finished. The method is very simple, low in cost, simple in principle, low in failure rate and simple in operation, can improve the construction efficiency, and can be operated by one person.
