Description

[0001] The present invention relates to an apparatus for press-fitting files,

The present invention relates to an apparatus for inserting a file and a method of constructing the same by using a jack, and more particularly, .

So far, it has been used to inject cement liquid or mortar into the ground in most cases. However, it is difficult to secure and evaluate the quality of the construction result. , The restraining of additional settlement was mostly performed. In the case where the soft ground layer is thick or the height to be raised is large, there is a problem that excessive cost is required even if the foundation can be reinforced or raised.

In addition, in order to form the perforation for injection, it is necessary to carry the heavy equipment to the drilling position inside the structure, so that the construction itself may be impossible or additional damage may be caused. The use of high pressure air compressors or suspension punching methods may further impair the damage caused by air pressure or the liquefaction of the ground before the injection material has hardened. The method of boring by Auger was mostly not applicable to existing structures.

On the other hand, the method by press-fitting the steel pipe file is an eco-friendly method of noiseless silent noise. After the steel pipe file is press-fitted to the required hard layer, not only the lifting and basic reinforcement of the sub- And the internal strength of the indentation file is also accurately detected.

. However, in the case that the reaction force device can not be used for the subsided structure, that is, in applying the method by the above-mentioned file press-fitting in a limited closed space that is not opened, there is no development of a concrete support method for the press- There has been a need for technology development.

As a method for solving such a problem, the applicant has filed an application for an apparatus for performing an underground structure reinforcement method.

The reaction force supporting body is configured to include a reaction force such as a reinforcing bar or a steel bar to which the lower end is fixed to the lower part of the structure bottom from the inside of the structure and the upper end is fastened and fixed to the upper support body located inside the structure .

In order to install the reaction force sphere, the surface of the bottom plate of the structure is partially cut, and the reaction force holes are formed on the bottom plate of the structure by using the punching equipment. The reaction force holes are formed in the bottom plate of the structure at regular intervals. Next, a press-fit hole is formed in the bottom plate of the structure using a perforating machine so as to partially overlap the outer peripheral surface of the reaction force hole inside the reaction force hole. The press-fit hole is for setting an initial indentation position of an indentation such as a steel pipe file to be described later. Next, a fixing hole including an anchor plate is attached to a lower end of a reaction force source, which is a reinforcing bar or a steel bar. Then, a reaction force hole having the fixing hole formed therein is inserted into the reaction hole. When the fixing hole is caught by the lower portion of the structure bottom, . When the setting position of the reaction force sphere is held, the lower end of the reaction sphere, such as a reinforcing bar or a steel bar, is fixed to the reaction force hole through a filler such as high strength mortar grouting or the like. The reaction force sphere is installed as a reinforcing bar or a steel bar having a predetermined gap in the inside of the structure so as to protrude upward from the bottom of the structure at a predetermined height. The upper end of the reaction force sphere is fastened and fixed to an upper support body made of a circular plate material. That is, in the upper support body, the through holes are formed corresponding to the number of the reaction force fittings, so that the upper ends of the reaction force fittings are fastened and fixed by fasteners such as a fastening nut. Next, the press-fit body, which is a steel pipe, is initially set in the press-fit hole so that it can be easily press-fitted into the lower portion of the structure at the set position when receiving a subsequent press-

Normally, a steel pipe having a diameter and a length enough to be carried and set by a worker in a limited space is used. In the state where the steel pipe is initially set in the press-fit hole, a head reinforcement plate is selectively installed on the head of the steel pipe, and a pressurizing means such as a hydraulic cylinder having a predetermined capacity is provided between the upper plate supporter and the head reinforcement plate, . That is, the operation of the hydraulic cylinder is restrained by the reaction force supporting body, so that the steel pipe is press-fitted into the ground under the press-fit hole in the form of the reaction force.

As described above, in the case of inserting a steel pipe file, there is a problem that a separate reaction force supporting body must be provided when a steel pipe is provided on the adjacent side, and accordingly, a large amount of cost is required and the work performance can not be improved .

Meanwhile, the inventor of the present invention has filed a filing application for a pile-inserting device for a pile steel pipe and a method for reinforcing a pile of the same by registering the method of repairing or reinforcing the existing structure using the reinforcement system of the existing structure using the reaction force of the joining means.
