Description

Ground reinforcement method and excavator bucket applied to the method {wedge foundation method and bucket using the same}

The present invention relates to a ground reinforcement method and an excavator bucket applied to the method, and more specifically, to a ground reinforcement method and an excavator bucket applied to the method, which can perform earthwork and ground nailing work simultaneously, thereby increasing construction efficiency, thereby reducing construction costs and shortening the construction period.

Soft ground is generally a general term for weak ground that cannot support superficial structures, and includes, for example, soft clay, loose sandy soil, and organic soil of dredged soil soft ground.

About 70% of our country is mountainous, and the remaining 30% is mostly agricultural plains, and these plains are developed along large river basins and coasts. Most of these plains are composed of soft, unconsolidated strata deposited during the Quaternary Alluvium. Soft ground generally refers to soft natural grounds formed along coasts or riverbanks, as well as artificial grounds such as dredged landfills. If such soft grounds are left as they are, the amount of subsidence will be excessive and the bearing capacity will be insufficient, which will cause safety problems.

In particular, in order to install structures such as roads, ports, or simple buildings on top of soft ground such as dredged soil, the moisture (water) contained within the soft ground is quickly dehydrated to improve the soft ground.

In general, a typical method for dehydrating moisture (water) such as pore water or excess water in soft ground is to horizontally lay a non-woven geotextile mat as a ground protection reinforcement and horizontal drainage mat to separate the surface of the soft ground and the horizontal drainage layer and to enable the operation of construction equipment, etc., and then form a horizontal drainage pipe and a horizontal drainage layer made of sand with good drainage properties on top of it, and then construct and install a vertical drainage pipe inside the soft ground, installing one end of the vertical drainage pipe so that it protrudes from the soft ground, and then stack a fill layer and apply a predetermined pressure necessary for dehydration and consolidation promotion by a load consolidation or vacuum consolidation method, thereby promoting dehydration of moisture (water) such as pore water or excess water in the soft ground.

Conventionally, typical load consolidation or vacuum consolidation methods for soft ground have utilized the principle of dehydration improvement, and typical construction structures used therein include sand drains, paper drains, and plastic drains. The above-mentioned sand drains, paper drains, and plastic drains have been pointed out to have shortcomings such as insufficient strength, clogging, insufficient water permeability and drainage, and insufficient durability. For example, the above-described plastic drain method uses a plastic drain board composed of a core material and a non-woven geotextile filter for vertical drainage that surrounds the core material, and the core material of the plastic drain board is formed of a plastic resin, typically polypropylene (PP) or polyethylene (PE), and has a plurality of cross-shaped grids formed on its outer periphery, and is composed of a plastic molded material having a predetermined length, such as 30 m, 50 m, or 70 m, and functions as a body for supporting the plastic drain board, and the non-woven geotextile filter is formed to surround the core material and performs the most important absorption and drainage functions of the plastic drain board, and the flow path formed between the core material and the grids of the non-woven geotextile filter functions as a conduit that vertically draws up and discharges pore water or excess water in soft ground that is sucked in through the non-woven geotextile filter.

In particular, most of the existing technologies use sand mats, and in this case, not only is the bottom tensile mat easily damaged, but the use of expensive sand mats is essential, which significantly increases the installation cost. In particular, the problem of being unenvironmentally friendly has been raised.

Accordingly, a ground reinforcement method using an eco-friendly inorganic ground reinforcement composition has been proposed. This is a method of reinforcing soft ground by injecting an eco-friendly inorganic ground reinforcement composition using the method of FIGS. 1 to 4.

Of course, these methods are somewhat effective, but they are difficult to apply alone when installing structures such as factories and warehouses on general land.

In other words, when installing structures such as factories and warehouses on general land, it is difficult to reinforce the ground using only the above method because the ground condition is soft. Even if the above method is performed, the construction period is bound to be delayed because the process is complicated in the case of conventional technology.

In particular, in the case of conventional technology, the soil work and ground nailing work had to be carried out separately, which inevitably increased the construction cost and delayed the construction period, and thus the need for technology development to supplement this has arisen.
