The present invention provides a plurality of water filling the water without filling the drainage layer after forming a drainage layer so that the drain member on the surface of the soft ground is not exposed, while a plurality of drain members are embedded in the soft ground so that the upper end portion is exposed The present invention relates to a soft ground improvement method using a water container, by stacking containers so that moisture of the soft ground pressed by the load can be discharged and removed.

In order to build various buildings or structures such as houses, factories, roads, dikes, etc. on soft grounds such as riversides, lakes, and swamps, construction that reinforces the strength of soft grounds by discharging moisture contained in the soft ground to the ground must be preceded. Bars may be used for this purpose, but the drain members may have a variety of structures. Typical examples include plate-shaped drain boards and perforated pipes having a plurality of through holes penetrated through the inner and outer circumferential surfaces thereof.

As illustrated in FIG. 1, the drain board 1 includes a plate body 11 such that a plurality of valleys, that is, drainage grooves D, are formed along the longitudinal direction on both sides of the plate body 11 having a rectangular shape. A plurality of ribs parallel to each other from the upper end to the lower end of the) upright, the outer surface is embedded in the soil wrapped in the filter member (2), such as non-woven fabric, the drain board (1) is soil When vertically embedded therein, as shown in FIG. 2, only moisture contained in the soil passes through the filtering member 2 to move to the plate body 11 side, and the moisture is formed by capillary action. After rising along the drain groove (D) formed between the (12) is discharged to the ground surface through the upper end of the drain board (1).

As shown in FIG. 3, the perforated pipe 2 is formed in a spiral wall or regularly repeated shape in the pipe wall instead of a flat straight pipe along the axial direction, and penetrates the inner and outer circumferential surfaces thereof. A plurality of through-holes (h) is used in the form of a spirally formed corrugated pipe, which is also embedded in the soft ground in a state in which the filtration member is wrapped on its outer peripheral surface.

As shown in FIG. 4, a plurality of drain members 10, such as the drain board 1 or the perforated pipe 2, are vertically embedded in the soft ground 3 so as to protrude from an upper end thereof. In the indicator, a plurality of separate drain members 10 ′ are horizontally arranged to cross each other to serve as drain pipes.

At this time, each of the drain members 10 and 10 'is wrapped in a filtration member such as a nonwoven fabric, and the drain members 10' arranged horizontally with the upper end of the vertically embedded drain member 10 may be connected to each other. And may not be connected.

After the installation of the drain members 10 and 10 'is completed as described above, the drainage layer 4 is stacked on the surface of the soft ground 3 using sand or gravel so that the drain member is not exposed to the outside. 4) to build up the soil layer (5) by stacking the soil brought in from the outside, the moisture contained in the soft ground (3) is vertical as the soft ground (3) is pressed by the weight of the fill layer (5) The water is collected in the drainage layer 4 along the drainage groove D or the hollow H of the embedded drain member 10.

At this time, the water barrier layer (not shown) is installed on the interface between the drainage layer 4 and the soft ground 3 surface, so that the water discharged to the drainage layer along the vertical buried drain member 10 does not flow into the soft ground.

Then, the moisture collected in the drainage layer 4 is discharged and removed to the outside of the drainage layer 4 through the internal pores of the drainage layer 4 itself or horizontally installed drain member 10 'so that the soft ground 3 is firmly compacted. do.

As described above, the conventional method for improving soft ground using perforated pipes requires a large amount of external soil to press the soft ground, that is, to accumulate the fill layer 5, so that a large amount of soil can be brought into the soft ground. If not, there is a problem that can not be applied.

Therefore, in order to solve the disadvantage that a large amount of soil for forming a fill layer as described above, a method using water in place of the soil has been published in Korea Patent Publication No. 195689, this patent is a soft ground After installing the perforated pipes, the texol layer is stacked on the surface of the soft ground to be removed, the texol bank is stacked at the boundary, and the nonwoven layer and the waterproof skin layer are laminated on the texol layer and the surface of the texol bank. Instead of filling the water, by pressing the soft ground by the weight of the water is a method of removing moisture.

Although the above patent is a method that can be effectively used when it is difficult or difficult to obtain soil from the outside, it is less than the amount of fill layer to build a 'texol layer' and 'texol embankment' on the drainage layer, but a considerable amount of special material There is a disadvantage that 'Texol' is needed.

In addition, as the moisture contained in the soft ground is removed, the soft ground inside the texol embankment sinks, but does not settle to the outer effluent drainage side facing the texol embankment, so that the water collected in the drainage layer on the soft ground surface can flow to the drainage side. There is no problem.

That is, since the position of the drainage channel is relatively higher than the sinked drainage layer, water cannot be discharged from the lower drainage layer to the high drainage side.

Therefore, as the soft ground subsides, it is difficult to discharge moisture contained in the soft ground, and eventually there is a problem that water removal can only be stopped.

In addition, when the soft ground subsides, the damage of the waterproof outer layer may increase, causing damage, such as tearing, and water in the embankment may flow into the soft ground, and it is almost impossible to accurately determine the location of the damaged part of the waterproof outer layer. There is no problem.

The present invention is to solve the problems of the conventional soft ground improvement method of removing the water contained in the soft ground by the pressure of the water filled in the dike after stacking the dike on the soft ground, texol layer or texol It does not require a specific material for dikes, etc., it may not build a dike if necessary, and there is no need to install a waterproof membrane to fill water in the dike, and as the soft ground subsides, it becomes increasingly difficult to remove moisture. It is an object of the present invention to provide a soft ground improvement method capable of continuously removing moisture over a long period of time without a phenomenon that eventually becomes impossible.

The above object of the present invention is achieved by a plurality of water collection vessels upright with the lower end embedded in the drainage layer of the soft ground surface, and a water container capable of filling water.

In the soft ground improvement method using the water container of the present invention, by laying a dike at the edge boundary of the soft ground to be water removal, by stacking a water container filled with water in the dike, the soft ground by the load of the water container As it is pressed, the water inside thereof rises above the soft ground surface through the drain member and collects in the sump wells installed in the drainage layer.

In addition, the construction method of the present invention is not only a specific material as a material for stacking a levee, but also for building a levee, as long as a levee having a suitable height can be stacked on a flat land such as various artifacts such as blocks, as well as natural products such as soil, stone, sand, and the like. It is not limited to the kind of material, and only the drainage layer which was conventionally basically laminated on the soft ground in the bank is formed, and there is no need to cover the bank and the drainage layer with a waterproof film.

In addition, the method of the present invention is to be installed in the drainage layer on the surface of the soft ground in the embankment in the state in which the lower end is embedded and a plurality of water collecting wells having a tubular structure, the water collected in the drainage layer to the outside of the embankment by a drain member or the like. By collecting the sump in the dike without direct drainage, the water is removed directly from each sump, allowing continuous drainage regardless of subsidence of the soft ground.

According to the method of the present invention, a dike is formed along the soft ground boundary of the dehydration object, and a plurality of water collecting wells are installed upright in a state in which a water barrier is placed on the deductive ground inside the embankment, and a drainage layer is formed on the water blocking film so that the lower end of the water collecting well is embedded. After forming a plurality of water container filled with water on the drainage layer, the water inside the soft ground through the drain member vertically embedded in the soft ground and the drain member connected horizontally to the drainage layer and then connected to the collecting basin By the load of this filled water container, it collects in a sump through a drainage layer.

In addition, the water collected into each sump is discharged to the outside of the dike using a separate pump. Since the sump is located on the soft ground in the dike, the catch level is settled to the same depth with the soft ground. Regardless of the subsidence of the ground, the catchment can continuously collect moisture from the soft ground.

At this time, the water collected in the sump may be injected into the water container outside the sump without discharging it to the outside of the dike.

That is, as the soft ground subsides, an additional empty water container is placed on the water container settled in the dike, and then filled in the empty water container without discharging the water collected in the sump to the outside of the dike. It is also possible to increase the pressure to press the soft ground further.

In addition, by recycling the water collected in the sump to the water container, it is possible to minimize the amount of water to fill the water container.

In addition, in the construction method of the present invention as described above, it is preferable not to build a dike that requires considerable time and cost, since each water container filled with water serves as a load applying block.

In other words, it is possible to simply stack the water container on the soft ground to be dehydrated without the dike, in which case it is possible to shorten the soft ground improved air, as well as reduce the cost.

However, if necessary, the dike may be constructed, and if there is a dike, there is an effect of concentrating the load of the water container stacked on the edge of the soft ground into the dike.

In this case, the water container may be made of a very tough and flexible tarpaulin, such as a tent paper with two or more sheets of synthetic resin sheets overlapped, a plurality of fibers interposed between the overlapping synthetic resin sheets, the appearance of the tank fixed The bar may be made in a shape, in consideration of transportation, storage, and the like, may be folded freely in a state in which water is not filled, and the former may be more preferably minimized in storage space.

That is, the water container may be made in the form of a water bag that can change its shape in a state where water is not filled or in the form of a bucket in which its appearance is fixed even in the absence of water. In one case it is convenient to build a dike, but it is not necessary to build a dike.

And, the water container may be placed on the soft ground to be dehydrated in the state filled with water, but in such a case, heavy equipment such as a crane may be needed to handle the water container of a considerable weight. The container may first be placed in soft ground and then filled with water.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

Figure 5 shows a process block diagram for carrying out the present invention method, Figure 6 shows a schematic construction structure for the soft ground drainage to which the present invention method is applied.

As shown, the soft ground improvement method using the water of the present invention,

Vertically embedding the plurality of drain members 10 such that the upper ends thereof are exposed to the soft ground 3 to be dehydrated;

Installing a water-repellent film (6) using vinyl or the like on the surface of the deductive ground (3) so that each vertically embedded drain member (10) is exposed through;

Stacking a dike (7) along a boundary of the soft ground to be dehydrated (3);

A step (400) of vertically installing a plurality of water collecting wells (8) having a tubular structure on the water curtain film (6);

A step (500) of horizontally installing a plurality of drain members (10 ') on the water-repellent membrane (6) inside the bank (7) such that at least one of the ends of the both ends is coupled to the sump (8);

Forming a drainage layer 9 by laminating sand or gravel on the water repellent film so that the lower end of the water collecting wells 8, the upper end of the vertical buried drain members 10, and the horizontal buried drain members 10 ′ are not exposed. )Wow;

Placing a water container (11) on the drainage layer (9) in the dike (7) except for the sump (8);

Filling the water container (11) with water (W) is made of a sequential process, such as step (800).

In this case, as shown in FIG. 7, the embankment construction step 300 may be omitted.

In addition, the step 800 of filling the water W into the water container 11 may be preceded by the step 700 of placing the water container 11 on the drainage layer 9.

In addition, in the case of constructing the dike 7, the material for the dike 7 is not limited to its kind such as soil, stone, sand, gravel, rocks, blocks, and the like, but only to a certain height. As long as it is a material that can be stacked, the insulation film 6 may be made of a waterproof sheet such as vinyl, waterproof curtain paper, tarpaulin paper, or the like.

When the construction of drainage and reinforcement of the soft ground in accordance with the above-described method of the present invention, the soft ground (3) is pressed by the load of the water container (11) filled with water and stacked on the drainage layer (9) soft ground (3) ), The moisture contained in the 이동 is moved upwardly to the drainage layer 9 along the vertical buried drain member 10, and the water collected in the drainage layer 9 flows along the horizontal buried drain portion 10 ′ inside the collecting well 8. The water in the sump 8 is discharged to the outside of the soft ground to be dehydrated.

In this case, the water container may not be completely filled with water, or after additionally stacking an empty water container on the water container filled with water, the water container which is not filled with water may be filled with water collected in the sump.

In addition, in the method of the present invention as described above, as the moisture contained in the soft ground 3 is removed, the soft ground 3 gradually sinks, as shown in FIGS. 8 and 9, and the water collecting well 8 and Since the water container 11 also sinks together, the water collecting well 8 can continuously collect moisture in the soft ground 3.

Of course, the sump 8, which was installed upright with the settlement of the soft ground 3, may be inclined somewhat, but does not affect its function.

In addition, the drain members 10 and 10 'used in the method of the present invention can be used irrespective of their type and structure, and the drain members having different structures, for example, the vertical embedded drain member 10. It is a drain board, and the horizontal embedding drain member 10 'may be used as an oil hole tube, but an appropriate drain member may be used according to a construction environment, but an oil hole tube is preferable as the horizontal embedding drain member 10'.

As described above, the soft ground improvement method using the water container of the present invention does not need a significant amount of external carry-on soil to press the soft ground, and also because it does not need to build a room, the construction cost is greatly reduced. Not only is it possible to reduce the construction period, it is also possible to significantly shorten the construction period, and because it uses a water container, construction is possible regardless of the place and there is an advantage that it is possible to continuously remove moisture despite the settlement of the soft ground.
