Description

Automatic insertion device that inserts the support into the ground hole

The present invention relates to an apparatus for performing a process by inserting a support into the ground, and more particularly, to an automatic insertion device that can ensure improved input precision by matching the center of the perforation communicating the ground with the center of the support .

When constructing a structure on the upper side of the ground, construction is carried out under the assumption that the ground is in a stable state. Therefore, it is common to carry out a separate ground improvement on the ground that does not meet the specific criteria for the structure.

When roads and railroads are built on soft ground, the most common practice is to pile up the soil. A method of increasing the strength of the soil by consolidating and dewatering the clay layer mainly by the sand-drain method is used. It simply increases the density of the clay layer, but it can reduce the amount of settlement of the embankment and prevent the destruction of the ground.

In recent years, subtypes of sand drain methods have been widely used, such as chemical hardening of the surrounding ground by adding various binders to the sand drain, or aggressive consolidation and dehydration of the clay layer and strengthening of the sand drain itself by strongly compacting the sand drain.

However, when the foundation ground of an already installed structure is weakened by various influences or damage is expected due to excavation of the adjacent ground, an injection method that strengthens the ground itself is used. The injection method for stabilizing cement and chemical by injecting pressure into the ground reinforces the ground by inserting a separate packer that permeates the chemical into the hollow after performing a drilling process to create a hollow in the ground. .

Korean Patent Publication No. 10-1065784 describes a packer equipped with an injection pipe and a technique related to the ground order and reinforcement method using the packer. By forming a perforated hole in the ground, and injecting a separate grout material into the ground with a packer inserted into the perforated hole, the hardness and strength of the soft ground are improved.

However, if the packer to be inserted into the drilling hole is not correctly inserted into the center of the drilling hole, the grout material that is later penetrated is unevenly penetrated into the drilled hole, so the expected ground reinforcement may not be realized. have.
