Description

System for restoration of disparity sinking construction

More particularly, the present invention relates to a system for responding to an unequal subsidence, which is provided in a lowest basement of a building to prevent or restore the uneven settlement occurring in the building.

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, referring to FIG. 1, cracks, sinks, or collapses of a building must have no effect on adjacent buildings, surrounding grounds, and environments of the building 101. Also, as time elapses after the construction, cracks, breakage, and uneven settlement occur in the structurally weak portions due to insufficient holding force against the building 101 own load. At this time, the most structurally weak part of the building 101 can be regarded as the lowest level 103 located at the lower end of the building 101, and horizontal settlement occurs in the lowest level 103, 109 are inclined, and the foundation supporting the building 101 also sinks.

That is, when the building 101 is not repaired or reinforced, there is a problem that the safety of the upper building 101 is seriously affected by the uneven settlement occurring in the lowest basement layer 103, and eventually collapses . To this end, various efforts have been made to prevent the damage of the upper layer of the building 101 caused by the uneven settlement of the lowermost layer 103 of the building 101 in advance.

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 technique, there is a method of removing the building after demolishing the building, and there is also a problem that it causes a huge amount of industrial waste due to the demolition, thereby 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).

The present invention can also provide a system for responding to an uneven settlement that allows the wedge portion to be automatically inserted by the prestressing member of the present invention to restore the upper structure to the original state even if uneven settlement occurs in the lower layer of the building.

In order to accomplish the above object, the present invention provides a system for coping with a subsidence settlement, comprising: a differential settlement preventive unit installed in a lowest basement of a building; and a lower level subsidence prevention unit provided between the uppermost level of the building and the lowest basement in a diagonal direction with respect to the lowest basement A prestraining member having a tensile force against the uneven settlement of the building, and a settlement countermeasure member connected to the prestressing member to prevent or restrain additional settlement of the building.

The upper surface of the first hydraulic cylinder and the second hydraulic cylinder may be in contact with the lower end of the wall of the building minimum floor.

When the lower end of the wall presses the second hydraulic cylinder by the uneven settlement of the building, the fluid of the pressurized second hydraulic cylinder flows into the first hydraulic cylinder through the fluid channel, So that the wall can be raised.

When the wall rises by the rise of the first hydraulic cylinder, a space may be formed between the wall and the differential settlement prevention part.

The settlement countermeasure member may be inserted into the space formed between the wall and the differential settlement prevention portion by the tension of the prismatic member to prevent further settlement of the building or the wall.

The sink receiving member may include a wedge portion inserted into the space and a plurality of protrusions formed on a surface of the wedge portion.

The system 100 for coping with unequal subsidence according to the present invention is a system installed in the building 101 so that measures can be taken so that deformation does not occur in the structure of the upper layer even if the lowest basement layer 103 causes uneven settlement.

Hereinafter, the present invention will be described in detail with reference to the drawings.

2 is a view showing a state in which the system 100 for coping with subsidence according to the present invention is installed in a building 101 or a wall 105. Fig.

2, the system 100 for coping with subsidence according to the present invention includes a differential settlement prevention unit 110 installed in a minimum basement 103 of a building 101, a minimum basement 103 of the building 101 A prestressing member 130 and a prestressing member 130 which are provided between the uppermost end 109 and the lowermost grounding layer 103 of the building 101 diagonally with respect to the base 101 and have a tensile force against the uneven settlement of the building 101 And a settlement countermeasure member 150 that is connected to prevent or restrain additional settlement of the building 101.

That is, when a uneven settlement occurs in the lowest basement layer 103 of the building 101, the present invention prevents the additional unequal settlement so that the unequal settlement is no longer generated through the unequal settling prevention section 110, Can be restored.

At this time, in order to restore the settling amount of the building 101 caused by the uneven settlement or to prevent additional uneven settlement, a prestraining member 130 having a tensile force and a portion corresponding to or inserted into the unevenly set portion due to the tensile force of the prestraining member 130 A subsidence countermeasure member 150 may be provided.

The prestressing member 130 is provided between the uppermost end 109 of the building 101 and the lowest basement layer 103 in the upper diagonal direction from the lowest basement layer 103 to the inside or outside of the wall 105 of the building 101 . The prestressing member 130 may be provided as an elastic means having a tensile force to prevent further anisotropic settlement of the building 101 or to restore a certain amount of settlement, and the material and kind thereof are not limited.

That is, the prestressing member 130 can prevent the uneven settlement of the building 101 by applying a tensile force in advance to a part where the uneven settlement is expected through the structurally weak part or the design analysis program.

FIG. 3 is a schematic view of a differential settlement prevention unit 110 according to FIG.

3, the differential pressure relief portion 110 according to the present invention includes a first hydraulic cylinder 111, a second hydraulic cylinder 113 having a cross sectional area smaller than that of the first hydraulic cylinder 111, And a fluid pipe 115 connecting the first hydraulic cylinder 111 and the second hydraulic cylinder 113. The first and second hydraulic cylinders 111 and 113 and the fluid channel 115 are filled with working fluid.

More specifically, the differential settlement preventing section 110 can be said to be a member operated by the principle of Pascal. Pascal's principle is that the force applied to a fluid filled in a confined space acts as a pressure on each side of the confined space. At this time, when the force F1 is applied to the piston having the sectional area A1, the force P1 applied to the A1 is transmitted through the fluid to the piston having the same pressure P2 and the sectional area A2. This can be expressed as F2 = A2 / A1 * F1, where F2 can produce a force equivalent to the area ratio of A2 / A1. That is, even if a small force F1 is applied in a narrow area, it can be seen that if the cross-sectional area of the other side is widened, it can act as a large force.

When the second hydraulic cylinder 113 having a small area receives a load (pressure) of a magnitude corresponding to the uneven settlement of the building 101, The first hydraulic cylinder 111 having a large area can be raised. At this time, the upward force F2 of the first hydraulic cylinder 111 can be given by the area ratio of A2 / A1.

That is, according to the present invention, a small force F1 is applied to the second hydraulic cylinder 113 having a narrow cross-sectional area, and the fluid in the second hydraulic cylinder 113 is moved by the force F1 through the fluid line 115 And the first hydraulic cylinder 111 having a large cross-sectional area is acted by a large force F2 to be raised by the force of the second hydraulic cylinder 113. The minimum underground layer 103 It is possible to provide an unequal subsidence countermeasure system 100 in which the installation is very simple and the ease of installation is improved while preventing or restoring the subsidence portion of the subsidence subsided.

Accordingly, the differential settlement prevention unit 110 according to the present invention repeats the method of pushing up the wall 105 or the lowest basement layer 103 of the building 101 by using the force (settlement amount) generated due to the unequal settlement It is possible to prevent or restore the uneven settlement of the lowest basement layer 103 of the building 101 having a large load more.

Meanwhile, a conventional hydraulic jack, jack support, or the like can be used as the differential settlement prevention part 110. The type, capacity, and driving method of the differential settlement prevention part 110 can be changed according to the field conditions, the specifications of the structure supporting means,

In addition, the differential settlement preventing section 110 can be manufactured and installed so as to have a capacity to raise the lowest basement layer 103 or the vicinity thereof.

That is, when the differential settlement preventing section 110 is operated, the first hydraulic cylinder 111 rises and lifts up the wall 105 or the lowest basement layer 103 of the building 101, (Load) of the first hydraulic cylinder 111 and the second hydraulic cylinder 113 is calculated in consideration of the vertical rising displacement of the first hydraulic cylinder 111 by calculating the maximum pressure (load) You can set the height.

It is possible to confirm or determine the structurally weak portions at the time before the construction by designing programs and to install several different settlement preventing portions 110 in the lowest basement layer 103 in consideration of the operating load state of the building 101 have. That is, since the differential settlement preventing unit 110 is applied to all the local parts where uneven settlement may occur, the installation, transportation, and manufacturing costs of the different settlement preventing unit 110 can be efficiently operated.

In addition, a support plate for supporting the first hydraulic cylinder 111 and the second hydraulic cylinder 113 of the differential pressure relief portion 110 may be further formed at the lower end of the differential pressure relief portion 110 . Or the foundation of the building 101 may serve as the supporting plate.
