| 摘要 |
The present invention relates to a pressing type nailing apparatus installed inside a punching hole formed on the ground, comprising: a packer which selectively opens and closes the punching hole; an injection tube which injects a grouting liquid inside the punching hole; a reinforcing member mounted through penetration of the injection tube, wherein a top end is extended to an exterior of the punching hole, a bottom end extended to the bottom end of the punching hole, and which has sufficient strength to resist the stress of the ground; and a leakage prevention cap combined to the top end of the injection tube which prevents a leakage of the grouting liquid by sealing an area between the top end of the injection tube and the reinforcing member. The grouting liquid injected into the punching hole penetrates into the ground and reinforces the ground. According to the present invention, by using the leakage prevention cap, airtightness between the injection tube and the reinforcing member is able to be maintained such that leakage of the grouting liquid flowing in reverse from the injection tube is able to be prevented. |
