Benefits of technology

0026] The present invention is proposed in order to solve the above-described problems. An object of the present invention is to provide a packing apparatus for pressure type soil-nailing and soil-nailing construction method using the

Problems solved by technology

Generally, according to industrial development, it is unavoidable situation to develop a steep slope district such as a mountain district by production of housing complex or construction of new city, etc.
However, because such conventional soil-nailing construction method adapts gravity type grouting, solidifying time is long and grouting should be repeated about 3.about.6 times in order to supplement contraction phenomenon.

Abstract

The present invention relates to a packing apparatus for pressure type soil-nailing and soil-nailing construction method using the apparatus, can shorten a grouting time through pressure type grouting which seals completely grouting area, and can improve stability of a ground reinforcing body by filling liquid grout to even a gap between a boring hole and the ground and void of the ground.

Description

[0001] The present invention relates to a packing apparatus for pressure type soil-nailing and soil-nailing construction method using the packing apparatus. More specifically, the invention relates to a packing apparatus for pressure type soil-nailing and soil-nailing construction method using the packing apparatus which is suitable for sealing closely grouting area which is formed in a bored hole and improving construction efficiency through grouting by pressure, that is, filling pressuringly of liquid grout.BACKGROUND OF INVENTION[0002] Generally, according to industrial development, it is unavoidable situation to develop a steep slope district such as a mountain district by production of housing complex or construction of new city, etc.[0003] Accordingly, it is required to provide a construction method for slope stability that can satisfy construction efficiency, economical efficiency and preservation efficiency of environment as well as heighten an availability of land and secur...
