In general, the excavation of the ground when civil engineering and building construction. Particularly, when the foundation is to be strengthened or the basement is to be constructed, the ground is excavated to a considerable depth, so that the construction of the soil should not be collapsed so that the construction around the excavation portion does not collapse.

Accordingly, after drilling a plurality of holes along the excavation, the H-beams are embedded therein, and the H-beams are firmly fixed using soil or cement mortar, or various hardeners are used to harden the surrounding ground. The methods of fixing the pressure are adopted.

As described above, the H-beam embedded in the ground is recovered after completion of construction.

However, when the H-beam is fixedly installed by cement mortar, etc., it is very difficult to extract the H-beam after the completion of construction and recover it. Accordingly, labor costs are excessively increased along with defects that require excessive manpower and time to recover H-beams.

If the H-beams cannot be recovered, the H-beams will be corroded with enormous material waste and cause environmental pollution. In addition, when a rigidly installed H-beam is forcibly extracted using various machines or H-beam drawing machines, cracks are generated in the underground part of the building or structure, which greatly reduces the durability of the building or structure, and shortens the lifespan. The problem of being forced to follow the closing of the.

Therefore, to overcome this problem, a release agent is applied to the H beam surface before the H beam is embedded in the ground. The release agent is usually prepared by using paraffin wax and a solid lubricant as a main component and melt-mixing diesel oil or silicon at high temperature. When such a release agent is applied to an H beam, the applied release agent is solidified at room temperature and is H. By forming a film between the beam and the cement mortar, the H beam can be easily recovered after the completion of construction.

However, the release agent application is mainly performed by using a release agent spray gun, there is a problem in that the release agent dust is diffused into the atmosphere.

In particular, the release agent contains a lot of harmful components to the human body not only adversely affects the health of the worker, but also increases the fine dust in the air and adversely affects the environment, so that the release of the release agent dust in the atmosphere can be prevented It is very urgent to come up with a plan.
