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 packing apparatus which can shorten a construction term and improve construction efficiency by executing grouting at a situation which seals completely grouting area by injecting a quick forming expansion agent at the packing apparatus.
[0027] Another purpose of the present invention is provide to the packing apparatus for pressure type soil-nailing and soil-nailing construction method using the packing apparatus which is suitable for improving stability of ground reinforcements by filling liquid grout to even a gap between the boring hole and the ground and void of the ground through pressure type soil-nailing.

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.
Thereby, because conventional soil-nailing construction method prolongs the process, construction efficiency is depreciated, thus there was a problem that construction period becomes longer.
Also, because the bored hole is slanted downwardly, it is impossible to fill liquid grout in grouting area, a gap between the boring hole and the ground is produced, whereby there was a problem to provoke a fatal defect at ground reinforcements.

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...
