Construction method of earthquake structure using thumb pile and freestanding pile {METHOD FOR CONSTRUCTING SOIL RETAINING WALL STRUCTURE USING H-PILE}

The present invention constructs a two-row soil structure including a thumb pile and a self-supporting pile, and supports and supports the upper portion of the vertically installed thumb pile and the top portion of the self-supporting pile installed to be inclined by a predetermined angle using a belt and a connection member. By having a tension member connecting the upper and lower ends of the thumb pile, not only can improve the support characteristics of the thumb pile and freestanding pile, but also improves the bending strength of the thumb pile can provide a solid and stable earth structure It relates to a construction method of the retaining structure using piles and freestanding piles.

As is well known, earthquake structures are largely divided into rigid walls and flexible walls, which include retaining walls, stonewalls, slurry walls, cast in place piles (CIP), and earthwall walls in flexible walls. , Board pile walls, and the like.

These earthquake structures are originally temporary constructions used for the purpose of resistance to lateral pressure such as earth pressure and water pressure in the foundation excavation work. As the excavation work is frequently performed in urban areas recently, the main purpose is to settle the surrounding ground and protect the buildings. The purpose of use is becoming more diverse.

As described above, it is important to select a suitable type in consideration of the stratum state, site, and surrounding conditions.

In particular, it is necessary to install support structures for the safety of the surrounding ground and surrounding structures of excavation structures during the excavation, and the selection of such support structures should be appropriately considered in consideration of the ground and surrounding conditions of the excavation area.

On the other hand, the earthquake structure must have the flexural strength (compressive strength) that can support the earth pressure itself acting on the incision surface. If the flexural strength is insufficient compared with the earth pressure, shear failure of the retaining wall (brokenness) occurs and the flange of the thumb pile As the sediment is removed from the ground, it is very likely that the earth and sand will enter the construction site and cause a big accident.

Accordingly, in order to achieve the construction purpose of the earthquake structure, various structures of the earthquake structure including a thumb pile, a self-supporting pile, a wall of a wall and the like are being developed.
