{WATER PRELOADING METHOD USING STEEL SYSTEM WALL}

The present invention relates to a preloading method for improving soft ground, more particularly, to stabilize a ground through a preceding load by means of, and to quickly construct and demolish a dike to meet water conditions, This paper describes a method for constructing a waterproofing embankment by using a steel system system wall with excellent ductility and independence.

The preloading method of soft ground is a method to increase the bearing capacity of the ground by preloading the ground and to reduce the amount of settlement that can occur after installing the structure, and the embankment load loading method has been generally used.

However, the loading method by embankment load requires a large amount of soil (soil, buckle, stone, etc.) for embankment, and it is difficult to transport and purchase a huge amount of soil, and it is difficult to transport It takes a long time, and the air is lengthened. Also, after the consolidation is completed, there are many problems such as mining and so on.

In order to solve these problems, a water filling method has been introduced in which a bank structure is formed on a soft ground, a bank building is installed on a bank structure and a soft ground, and a certain amount of water is loaded on the bank building to use as a load.

Patent Document 1 (Registered Patent No. 10-0482975) discloses a structure in which a bank is installed and nonwoven fabrics are installed on the inside of a bank and an upper portion of a bank, adjacent tubes are installed to overlap each other in half, The tubes were placed at 90 ° to each other, and water was placed at the same rate as the tubes in the same layer. Water was placed in the order of the upper layer from the lower layer, and extra tubes were installed. And the soil is piled up to the height of the water tube to construct the embankment and install the tube in the embankment.

The prior loading method using water such as Patent Document 1 is about 1.8 times as high as the preceding load height of the soil so that the unit weight of water is smaller than the unit weight of the soil (soil, buckle, stubble, etc.) Water needs to be filled up. To do this, it is necessary to construct a tanks with huge tall soil, so it is hard to find practical applications because of lack of field application.

Patent Document 2 (Registration No. 10-0812656) discloses a water-load-bearing dam structure for landing a water load on a ground to stabilize a weak ground, and is connected to a floor surface in a standing state to form a rectangular- Several panels; A water receiving member positioned in a space formed by the panel-shaped panels to receive water; And a cable installed between the raised panels and supporting a load applied laterally to the panels by the water accommodated in the water receiving member. The present invention relates to a structure for supporting a water load, This is a problem to be solved by replacing a levee, a poor workability due to low independence of panels, and a separate cable being used.

As shown in FIG. 1, the method for constructing the embankment for water using the steel material system building wall according to the present invention comprises: (S10) installing a hypothetical wall; (S20) installing a mat; (S30) Drainage, and each step will be described in detail below.

(S10) Install a hypothetical wall.

The hypothetical wall 10 is a base structure for forming a lower portion of the material (the water is wound and the load is loaded by the load of the water, and is formed by the hypothetical wall and the mattress mat) And is composed of a combination of a plurality of walls 20 and a wall alignment socket 30 for supporting the wall 20.

As shown in Figs. 1 and 2, the wall 20 is a plate-like (box-like or the like) made of a steel material.

The wall aligning socket 30 preferably has a structure that stably supports the wall 20 to prevent the wall 20 from tilting or collapsing. The wall aligning sockets 30 include a ground seating portion 31 to be placed on the ground, And a wall support portion 32 to which the wall 20 is detachably coupled.

The shape of the wall 20 and the wall aligning socket 30 is small in volume so that it is easy to handle (manufacture, store, transport, and install) Since different kinds of walls can be installed, there is an advantage that the lower part of the material of various heights can be freely constructed.

The present invention is characterized in that the wall 20 and the wall aligning socket 30 are not separated but a hypothetical wall 10 (see FIG. 3) in which these 20 and 30 are combined, that is, a hypothetical wall 10 ). In the following description, the separation type of the wall 20 and the wall alignment socket 30 will be described.

The wall aligning socket 30 is of an L-shape in which a wall supporting portion 32 is erected at the end of the ground seating portion 31 as shown in Fig. 2, and a wall supporting portion 32 is erected at the center of the ground seating portion 31 as shown in Fig. Various shapes such as inverted T shape are possible.

It is also possible that the wall aligning socket 30 is provided with the wall through hole 33 (shown in Fig. 4) so that the wall 20 can be inserted into the ground rather than being engaged. Although the wall-through hole 33 is shown in the reverse T-shaped wall-aligned socket 30, the wall-through hole 33 is also applicable to the L-shaped wall-aligned socket 30 in FIG. According to the wall 20, the wall 20 and the wall aligning socket 30 are firmly erected on the ground, thereby preventing collapse of the bottom of the material. The wall 20 is not limited to being inserted into the ground through the wall through hole 33 as a whole but the wall 20 may be formed in two or more wall through holes at the bottom of the wall aligning socket 30 It is also possible to form two or more near-field sites on the bottom of the wall 20 so that the bottom portion between the near-field sites is seated on the bottom of the wall-aligning socket 30,

The coupling structure of the wall 20 and the wall aligning socket 30 is formed by a wall groove 34 (shown in Figs. 2 and 4) in the form of, for example, a wall aligning socket 30 and surrounding the periphery of the wall 20, Thereby inserting the wall 20 into the wall groove 34. As shown in Fig. The insertion of the wall body 20 is excellent in workability because no separate tool is used.

Of course, the coupling structure of the wall 20 and the wall alignment socket 30 is not limited to the insertion type described above, and various coupling methods (bolt, nut, welding, etc.) are possible.

According to the present invention, the wall aligning socket 30 is a fixed type having no change in the angles of the ground receiving portion 31 and the wall supporting portion 32, the separable coupling type of the ground receiving portion 31 and the wall supporting portion 32, An angle adjustment type of the portion 31 and the wall supporting portion 32 is possible.

As shown in FIG. 5, for example, when the water-filled portion is rectangular when viewed from the plane, the wall-aligned sockets 30 may be formed in a straight wall arrangement The sockets 30 are arranged in a rectangular shape.

Here, since the edge portion of the lower part of the material requires structural rigidity, it is more preferable to use the corner-type wall sorting socket 30-1 than to install the two straight wall sorting sockets 30 in such a manner that they are not engaged with each other desirable. The corner-type wall sorting socket 30-1 is configured so that two walls 20 perpendicular to each other are coupled.

The wall aligning sockets 30 are independent for the structural stability of the wall 10, and can be fixed by neighboring ones, fasteners such as bolts and nuts, and welding.

The wall-mounted sockets 30 may have a function of preventing the ground-receiving portion 31 from being conducted, but it is also possible to apply a separate conductive-preventing plate 40 in order to exert a greater conductive resistance.

The conduction preventing plate 40 receives a load of water from the upper portion thereof and supports the wall aligning socket 30 and the wall 20 and is coupled to the ground seating portion 31 of the wall aligning socket 30. [

The coupling structure of the conduction preventing plate 40 and the wall alignment socket 30 is the same as the coupling structure (insertion type, etc.) of the wall 20 and the wall alignment socket 30.

The wall 20 and the wall aligning socket 30 will be manufactured to a proper size for manufacturing and transporting and so the wall 20 and the wall aligning socket 30 are arranged in a line to constitute a lower part of the material At this time, it is desirable to increase the rigidity of the hypothetical wall 10 as a whole by connecting the neighboring walls 20 together to connect the walls 20 through the wall joint socket 50, as shown in FIG. 7 . The wall joint socket 50 is, for example, in the form of an H beam with a groove into which the wall 20 is inserted.

The wall joint socket 50 can be formed by forming a groove on the upper surface of the wall aligning socket 30 and inserting a bottom portion into the groove.

The wall joint socket 50 is not limited to being installed only between the walls 20 and it is also possible that only the wall aligning socket 30 and the wall 20 are combined or only the wall aligning socket 30 .

The wall 20, the wall alignment socket 30, and the like are used to construct the hypothetical wall 10.

The hypothetical wall 10 is fixed to the ground via an anchor or the like since the perimeter portion is formed in such a manner that the perimeter portion is shielded from the outside through the adjacent wall 20 (or the wall 20 and the socket 30, respectively) It maintains the self-sustaining state even if it does not exist. Of course, it is also possible that the hypothetical wall 10 is fixed to the ground via an anchor or the like for the purpose of increasing the self-supporting property.

(S20) Install the order mat.

After completion of the installation of the hypothetical wall 10 through the previous process, the hypothetical mat 60 is installed on the hypothetical wall 10 by the following method.

The mats 60 are laid on the bottom of the inside of the porthole 10 and the periphery is raised along the inner wall 10 of the portholes 10 so that the wall of the wall 20 And the lower part of the wall (10) is provided with a large bottom part.

The level mat 60 is fixed to the outer surface of the wall 20 or the wall alignment socket 30 (shown as being fixed to the wall alignment socket 30 in Fig. 9) through the fixing means 61 by the peripheral portion.

The fixing means 61 of the level mat 60 can be, for example, an annular type, a magnet type, a button type, a sticky type, or the like.

A plurality of such fixing means 61 are applied at regular intervals along the order mat 60 to uniformly fix all portions of the order mat 60.

A protection member 62 is coupled to the upper end of the wall 20 to prevent the waterproof mat 60 from being torn. The protection material 62 is bonded in a band shape so as to surround both sides of the upper end of the wall body 20 to prevent the order mat 60 from tearing by preventing direct contact between the order mat 60 and the wall body 20.

The protective material is not limited to an elastic material such as rubber, but may be a roller that is rotatably installed at the upper end of the wall body 20.

The order mat (60) is used by connecting a plurality of unit mats with water-tight sewing or the like in accordance with the size of the lower part of the material.

(S30) Preloaded by water.

After installing the hypothetical wall (10) and the waterproof mat (60), load water on the bottom of the material and load it on the ground.

As the load of water is deposited, the ground is slowly stabilized.

The hypothetical wall 10 and the waterproof mat 60 are gradually lowered together with the stabilization of the ground.

(S40).

When the preceding loading by water is finished, the embankment according to the present invention is demolished and the water below the material is first drained.

The drainage of water can be both forced drain by the pump and natural drainage by the water level. In the latter case, the drainage hose 70 and the drainage hole 71 are formed, as shown in FIG.

The drain hole 71 is formed so as to communicate with the inside and the outside of the lower portion of the material and is formed so as to communicate with the wall aligning socket 30 and the wall 20 at the overlapped portion of the wall aligning socket 30 and the wall 20 And only the wall-aligned socket 30 is formed at a portion that does not overlap with the wall 20.

The drainage hose 70 is connected to the inside of the waterproof mat 60 after passing through the water drain hole 71 to drain the water in the waterproof mat 60, So that it is opened only when the water is drained to drain the water.

The drainage of water using drainage hose (70) is carried out by discharging the water from the wire rod area to the postage area through the drainage hose (70) after the discharge of the wire roots, , See Figure 11).

After the drainage of the water is completed, the waterproof mat 60 and the temporary wall 10 are removed. First, the waterproof mat 60 is released from the fixing means 61, And folds the level mat 60 in the hypothetical wall 10. [

Subsequently, the wall 20 is separated from the wall aligning socket 30 for disassembly of the hypothetical wall 10, then loaded on the vehicle, and the socket 30 is lifted from the ground and loaded on the vehicle.
