Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repairing equipment and a repairing method,

The present invention relates to a maintenance apparatus and a maintenance method for a unconfined subsidence, and more particularly, to a maintenance apparatus and a maintenance method for a subsidence settlement building, which are capable of supporting a subdivided building and at the same time, And a maintenance method.

Generally, it is common for most of the buildings to construct underground structures while excavating the ground, and to form each layer on the underground structure. In recent years, the need for high-rise buildings in urban areas has been increasing. For the construction of high-rise buildings for this purpose, the safety of the buildings has been designed in such a way that not only the high-rise buildings' own loads but also disasters such as snowfall, It is difficult to confirm by just.

When the ground supporting the building is locally submerged for various reasons, the ground tilts to the subsidence, which seriously threatens the safety of the building. Accordingly, in order to restore the building to its original position, It is necessary to raise the site in any way.

In particular, cracks, sinks, or collapses in a building must have no effect on adjacent buildings, surrounding grounds, and the environment of the building. In addition, as time elapses after the construction, cracks, breakage and uneven settlement occur in the structurally weak part due to insufficient holding force against the building's own load. At this time, the most structurally weak part of the building can be regarded as the lowest basement located at the lower part of the building. Horizontal settlement occurs in the lowest basement, so that the top of the wall tilts and the foundation supporting the building also sinks.

In other words, when the building is not repaired or reinforced, there is a problem that it may seriously affect the safety of the upper building due to the uneven settlement occurring in the lowest basement, and eventually collapse. To this end, various efforts have been made to prevent damage to the upper floors of the building caused by uneven settlement of the lowest floor of the building.

Conventionally, in order to prevent uneven settlement occurring in a high-rise building, a technique of restoring the foundation where a uneven settlement occurred is a compaction pile grouting system (concrete pile grouting system) A similar settlement restoration plan has been announced. Alternatively, by using a hydraulic jack or the like, the load on the strut can be largely introduced, and the space between the strut and the wedge or the wedge and the earth wall can be eliminated, and the displacement of the wall of the building can be considerably reduced. In addition, a method has been introduced in which the subsided ground is filled with a urethane resin-based filler material, thereby raising the subsided ground.

However, this unequal settlement restoration technology is complicated and complicated to process the detailed construction method, requires high investment cost in advance, and if the building is unevenly settled due to a cause other than the subsidence, a system that only raises the local part of the building is selectively applied It was not possible. In addition, in order to apply the conventional uneven settlement restoration technology, there is a method of removing the building after demolishing the building, and a large amount of industrial waste is generated according to the removal of the building, which causes a problem of causing environmental pollution.

Therefore, even if a building is tilted or settled, it is not easy to restore only the portion that is depressed due to ineffective and uneconomical reasons as described above.

Accordingly, the present applicant has developed the present invention to solve the above problems, and related prior art documents include Registration No. 10-1103530 (entitled " Restoration of Unequal Deposits of Buildings & , Registration date: January 02, 2012).

Conventional building lifting apparatus is an impression system (10, Korean Patent Laid-Open Publication No. 2004-85894). The lifting system pushes a slab or the like of a building or the like by using a movable strut band inserted in a fixed paper main frame and a fixed paper main frame, the height of which increases or decreases in the longitudinal direction, the upper and lower cable support plates, the metal cable and the hydraulic cylinder It can be seen that the heavy weight structure is raised by repeating the lifting method.

However, since such an impression system is permanently installed in a structure and adopts a method of supporting the structure itself, there is a problem in that it can not be dismantled after temporarily installed in a building such as a building. There is a limit to the view that it can not be regarded as a fundamental repair method because it does not adopt a method of continuously supporting the building.
