Description

Vacuum preloading device of suction drain and method about for stabilizing highways, river banks, industrial complexes complex of rural areas, industrial estate and land}

The present invention relates to an individual vacuum consolidation apparatus using suction drain for stabilizing the ground of roads, river embankments, agricultural complexes, industrial complexes, and sites, and an individual vacuum consolidation method using the same, wherein a large amount of pore water contained in the ground of soft ground In the individual vacuum consolidation apparatus by suction drain which can be drained through the water-permeable drainage and stable treatment, the end portion of the drainage extension part connected to the drainage and the connection rope are connected by the clamping which is operated by no power and no load. In addition, by detecting the position of the float by the sensor to automatically detect the position of the drain tank and the collecting tank is formed to include a drain portion, it is easy to remove the connection rope and drainage extension, stop the operation of the drain for water level control Individual vacuum consolidation apparatus using suction drain that does not need to be applied and individual vacuum consolidation using the same Relate to.

In general, a vertical drain method is used as an improvement method for improving the strength of soft ground.

The vertical drain method is divided into a sand drain method, a pack drain method, a paper drain method, and the like according to drainage materials.

The sand drain method is a typical method of the vertical drainage method, and is a method for promoting the drainage effect by artificially pouring sand piles vertically in the soft ground using sand as drainage material, and the pack drain method is the sand drainage method. Similar to the drain method, but using a sand and a packet net that can hold the sand as a drainage, it is a method for promoting the drainage effect by artificially pouring vertically in the ground of the soft ground.

The paper drain method (aka plastic drain method) is also the same as the sand drain method. Similar, but in the form of a band wrapped with a textile fiber in a plastic core, the drain effect is generally less than the design calculations, and the construction cost is expensive, but there is an advantage that the construction management is easy, but this also has the advantage of efficiency and applicability Firm reliability is not secured.

The general trend is that in the case of ultra soft ground with a high water content, the pack drain method is used in the deep depth, and the paper drain method is used in the relatively low depth, and the sand drain is used in the soft ground where the water content is not very high. There is a trend in which construction methods are being used.

The demand for industrial and residential land is increasing along with economic growth throughout society, but it is difficult to secure business districts with good ground conditions. In addition, for the efficient and balanced development of the national territory, new space development is under way not only in areas with good soil but also in areas with weak soil. As a result, it is inevitable to change the business area to soft ground, which has poor ground characteristics and poor development conditions, in order to secure land. Therefore, active measures are required.

In addition, all of the above methods require an additional loading method (pre-loading method), so a large amount of soil is required when dealing with a large amount of soft ground.

However, considering the fact that environmental awareness has recently emerged, the problem of environmental destruction can be a very difficult problem to secure the earth and sand.

In addition, the loaded load may cause the shear failure of the ground due to sudden increase of shear stress, so it is necessary to carry out the step loading for a long time to avoid this, which is the increase of all expenses necessary for construction such as labor cost, before or after construction The large amount of work required to apply and remove loads, prolonged construction period due to stage fill, shear failure or unequal settlement due to the weight of the loaded load, and large shear stresses in the soft layer near the end of the loading site in partial loading At the same time, there were many defects in many aspects, such as the problem of causing significant shape deformation at the same time as the loading and not effective consolidation.

To compensate for this drawback and reduce air, a vacuum consolidation method was proposed in 1952 by Kjellman, Sweden.

However, the sealing sheet, which is the life of vacuum consolidation method, is expensive, and it is difficult to maintain the airtightness due to tearing during construction, and the amount of vertical drainage that has to penetrate the airtight sheet increases when applied to large sites. This requires a lot of drilling, and the complicated connection of pipes entails considerable difficulty in the construction.

Accordingly, Korean Patent Publication No. 2006-0096224 (published on September 11, 2006) discloses a soft ground improvement method using a vacuum consolidation method in which a gas tight cap is installed without using a gas tight sheet.

However, in this case, a lot of defects are caused by the airtight cap, and there is a disadvantage in that maintenance is difficult when the defect occurs.

In addition, most of the drainage system using vacuum consolidation method is difficult to continuously operate in the process of adjusting the water level of the pore water drained through the drainage, and the operation efficiency decreases accordingly, so that the continuous technology development of the whole system using the vacuum consolidation method This is necessary.
