The present invention relates to and in combination with of the file, such as a micro-file as a rigid body mesh (mesh) structure reinforced perforated mesh tube inserted into a perforated hole inside drilled in the ground and withdraw the casing injecting grout into the high-pressure grout has perforation holes the inner surface large without casing by to be attached has a frictional force using a rigid perforated networks that can exert sufficient bearing capacity in tosacheung of the ground pressure type file structure, and relates to the construction method, the pressure using a rigid perforated network according to the invention expression file structure is inserted into the space inside the casing is inserted into the perforated hole drilled in the ground, one casing and the support so the perforations after the removal are pulled out from the perforations fall down, consisting of a mesh (mesh) of rigid material the customs form and reinforcing mesh perforated tube; The reinforcing insert in the axial direction in the interior of the perforated tube networks and is characterized in that it comprises a file of a rod shape that is inserted into the casing interior with a hole is fixed to the reinforcing mesh tube by the coupling means, the reinforcing mesh perforated tube.
