Abstract

The present invention operates by installing a horizontal drainage module connected with a perforated pipe or drainage material, a vacuum and a drainage pump before landfilling and during landfilling the water of the dredged landfills dumped during the reclamation work using the high water-drained soil dredged from the seabed A device and method for promoting sedimentation and settlement.

Description

Dredged soil sedimentation and settlement promotion method using horizontal drain module and multi-stage installation device before and during landfilling {The Accelerating Method of Drain Equipments for settling and settlement at Reclaimed Materials}

Generally, the purpose of the general horizontal drainage method applied to soft ground improvement works is to act as an upper drainage layer for consolidation settlement of the soft ground, to prevent groundwater from rising into the fill layer, and to secure the trafficability of construction equipment. It is for forming a support layer.

Recently, the coastal reclamation and the construction of industrial parks and roads occupying coastal areas to secure large-scale new ports, new airports, new cities, industrial complexes and agricultural lands have been actively carried out. For this reason, it is difficult to secure landfilled soil, and we are actively using dredged soil, but the ground created by using dredged landfill and dredged soil arena was dumped with high water content over the liquid limit and the compressibility is very high. Even if left unattended for a long period of time, only the surface part is hardened by natural drying, which allows simple access of personnel. However, the strength of the ground is so low that it is difficult to enter equipment for ground improvement without a separate surface treatment.

In order to achieve this purpose, non-woven fabric, bamboo and sand, etc. to secure the equipment running (patent 10-2008-0099015; soft ground surface treatment method using bamboo net, patent 10-2009-0026904; horizontal vacuum drainage using oil pipes Or a method of securing strength by forcibly dehydrating the gap water of the support layer itself using a vacuum pressure or the like (Patent 10-1999-0046141; a number of methods for improving the surface layer portion of soft ground). However, such a general method is very low thickness of the ground which can be improved, excessive material costs such as sand for forming horizontal drainage layer, there is also a problem of environmental pollution.

In the present invention to solve the problems of the above method, by installing the drain module at the time of dumping the dredged soil and landfill soil, the new treatment method and the method which can achieve the volume reduction and strength increase through the water removal immediately after the dredged soil dumping Developed a device that can

The dredged soil dumped during site construction has a very high water content, compressibility, and consolidation over a long period of time. As a result, dredged soils require treatment facilities or sites in addition to landfills.

In particular, the dredged land is very low when the dumping is completed, it is necessary to further improve the ground to utilize the site. Various methods such as vertical drainage method and preloading method are applied to improve the ground, and the ground strength is very low, which incurs additional surface treatment cost for equipment entry, and the use of natural materials such as horizontal drainage layer and sand mat laying is inevitable.

In addition, in the case of the existing invention, the landfill layer that is applicable to the method applied after the dredged soil is dumped is very low, and the improvement efficiency is low. When the improvement is completed, it is lowered below the site plan line to secure additional sand or earthwork. Inevitably not economical.

By utilizing the method and apparatus of the present invention, the discharge rate of the pore water is very fast at the time of dumping the dredged soil, so that the dredging soil sedimentation, self-consolidation and settlement are promoted, so that more dredged soil can be buried in the same place. As the load is applied, environmental pollution can be minimized by greatly reducing the use of natural materials for surface treatment and ground improvement in the future site improvement.

The present invention facilitates sedimentation and consolidation by quickly removing water from a high water content dredged landfill soil dumped during landfill construction using soil dredged from the seabed when constructing a site using a drain module connected with a perforated pipe or drainage material, a vacuum and a drainage pump. Regarding the apparatus and method, hereinafter, the configuration and operation state made by the embodiment of the present invention will be described in detail with reference to the accompanying drawings, the accompanying drawings are only illustrative of the embodiments of the present invention in detail. The scope of the invention is not limited or limited by the drawings or the description with reference to the drawings.

1 shows a plan view and a cross section of a drain module device for promoting ground sedimentation and settlement, and FIG. 2 shows an installation method for the application of the present invention.

Referring to the dredged sediment and sedimentation facilitation treatment apparatus developed in the present invention, as shown in Figure 1, a certain size (the limit size of the frame can be increased or decreased depending on the capacity of the vacuum pump; in the present invention 50m x It is a structure that is fixed to the steel frame (1 shown in 50m) using a fixed ring (2) to the drain material (3) at a predetermined interval (CTC) and the disposed drainage discharges the gap water and the vacuum pressure and pressure load In order to be connected to the drainage system 4 and the vacuum pump 5 or the compressor 23.

Referring to the construction method of the device invented in the present invention, as shown in Figure 2 illustrates a method of installing the ground sedimentation and settlement facilitation device according to the width of the target area where the dredged soil is dumped wire narrow Alternatively, there is a method 11 for installing using a rope and a method 12 for installing using a skid or a moving device when the width is large. Figure 3 shows an example of applying a vacuum pressure to the ground to be embedded using the device of the present invention.

After the first stage dumping of dredged soil as shown in FIG. 3, the module (first stage) is installed, and the vacuum pressure is applied to the first stage module simultaneously with the second stage dumping, and the second stage module is installed at the same time with the second stage module. Loading the vacuum pressure can drastically increase the dredged soil dumping capacity by facilitating sedimentation and consolidation of the dredged soil, and can uniformly improve the entire landfill through continuous vacuum loading after the dumping is completed.

4 is a method of installing the drain module alone and connected to the vacuum pump and the compressor and the compressor connected in parallel to be installed in parallel to adjust the valves as necessary to selectively load the vacuum load or load load The method is shown.

5 is a comparison of the present invention and the existing construction method of the dredged soil dumping ground existing construction method is to improve the ground by pouring drainage after the dredged soil dumping is completed, the present invention is the construction period because the ground improvement starts at the same time dredged soil dumping It is very economical because it is possible to shorten and additional landfill can be secured by promoting settlement. In addition, since the strength of dredged soil after dumping is not required, surface treatment is not required to secure equipment runability for soil improvement, so stability and construction efficiency are very high.

The present invention facilitates consolidation and settlement of dredged soil at the time of dredged soil dumping time, which facilitates consolidation and settlement of dredged soil, so that more dredged soil can be buried faster in the same place. Equipment entry and improvement are possible.
