Abstract

The present invention relates to a multi-stage one-touch grouting (injection) apparatus, which inflates the louver packer using a conventional clamp nut and secures the airtightness of the injection hole to inject cement milk and mortar as a rubber band packer. After inserting into the injection hole, the handle connected to the clamp nut by screw is rotated to inflate the packer, so the work that takes about one to two minutes for artificial handle operation is ineffective and the handle does not rotate due to the damage of the screw. There is also a factor of stopping grouting, and the handle packer has many disadvantages of economical efficiency and workability, such as disposing of the cement mortar in the injection hole and discarding it after one or two uses.

In order to solve the above problems, a cam function is provided by injecting a cam mechanism or clamp mechanisms into an exterior of an injection device in which an injection tube is installed and sockets and packer louvers are formed on both sides. And the clamping function quickly and securely installs the injection device in a short time (1 to 2 seconds), so that the grouting operation can be realized quickly. Economical efficiency can be guaranteed by increasing the frequency of use more than 10 times by preventing the cement mortar (milk) from solidifying.In addition, grouting is performed by injecting cement mortar (milk) into 10-30 injection holes at the same time for reinforcing ground in civil works. It is to provide a multi-stage one-touch grouting injection device capable of shortening the time and maximizing construction efficiency.
