Variable Structure Temporary Retaning wall {Structure of Variable Temporary Retaning wall}

The present invention relates to a simple earth block structure that is installed on the side of the excavation portion in order to cope with soil pressure and prevent the collapse of the excavated soil during the ground excavation work such as pipe trench for underground pipe embedding, more specifically in the excavation direction displacement According to the present invention, it is possible to adjust the horizontal slope angle of the panel according to the present invention. It is possible to implement a simple earthen structure as possible has excellent workability and workability.

Generally, when the ground excavation work such as building underground structures such as underground floors of buildings, subways, or dig pipes to bury underground pipes, when the well-known area is wide around the layout of the building, a sufficient angle of relief can be obtained. In the case of a site where a sufficient angle of repose is not secured due to the site conditions, the earth wall is installed on the side of the excavation to prevent the earth wall from collapsing.

The cobble wall is a temporary construction that bears the side pressure such as earth pressure and water pressure generated during the excavation work, its variety is also various bars,

First, the thumb pile earth wall is to install the earth plate between two H-piles while drilling the ground, inserting the H-pile, and then excavating. It is a method of supporting an excavation wall by inserting a earth plate while inserting or boring and inserting it into the ground and proceeding excavation.

Reinforced concrete plates and steel plates made of ready-made products are also used as the earth plate of the thumb piling wall, but the most popular ones are wood earth plate, H-pile spacing, back earth pressure and The field application is determined according to the bending stress of the wood used as the earth plate, but the wood earth plate can play the role of the retaining wall, but it is difficult to preserve the uniformity of the wood and the change of strength according to the moisture content is large and the wall deformation There is a risk that the situation is somewhat problematic.

In addition, the thumb pile earthenware wall is the principle of recovery for reuse of the earthenware wall before refilling after placing the structure after excavation, but in reality, when dismantling work is not easy, only H-pile (H-PILE) As it is being drawn and reused, the recovery rate of the wood earthen board used as the retaining wall is low, which may be advantageous in terms of primary construction cost, but it is an uneconomical method in the long term.

However, in spite of the above-described discontinuities, there is no method to replace the thumb pile wall, which is still widely applied.

On the other hand, the retaining wall is a bar that can be installed as another method of steel sheet piles, the method of installing the steel plate piles to enable the role of the water wall and earth wall at the same time is mainly used where water-repellency is required.

The sheet piles, called sheet piles, have both ends of holes or irregularities so that they can be fitted together, so that one sheet pile is vertically grounded, and then one end of the connection part By fitting the end of the sheet board and embedding it in the ground, one assembly mud wall is created, and when the steel sheet pile and the sheet board are repeatedly assembled in the ground, one order wall is installed, and the mud wall installed by the above process is installed.
