The present invention relates to a two-sided support environment wood retaining wall and a construction method thereof that significantly increases the retaining wall height by using prestressed cam beams and saw timber nailing, and after installing vertical timber at regular intervals up to a predetermined height (about 3.0 m), To protect the slope by installing horizontal timber supporting it in the horizontal direction, the timber nailing is installed in the ground of the back filling to be stabilized at regular intervals in order to pursue the stability of the retaining wall, so that the retaining wall is shot against the force acting by earth pressure A method of constructing a double-sided support environment wood retaining wall using a timber nailing that is resisted by the frictional force of timber nailing. Both ends are supported by spring by supporting pre-stressed cam cable The significant improvement in the structural system relates to both ends of the supporting environment timber retaining walls and methods for their construction using the prestressing kaembim to further increase the height of its application.

In general, retaining walls are used to construct roads, railroads, complexes, and rivers in cut soil, and to construct soils and protect slopes on a certain cut surface to minimize site limitations, slope stability, earthwork reduction, and environmental damage. to be.

Here, the conventional retaining wall includes a reinforced concrete retaining wall, a reinforcement earth retaining wall, a reinforced steel nailing and a retaining wall reinforced with concrete, a concrete block retaining wall, and the like.

Most of the retaining walls mentioned above are constructed by reinforced concrete molding and inorganic material blocks for construction and soil reinforcement, so as to increase construction cost, increase air, environmental damage, natural topography and incongruity, lack of environmental resilience, and aesthetics. Inhibition, color fading, rain and sedimentation and environmental pollution, there is a problem that the natural ecosystem is destroyed.

In addition, when building the retaining wall with reinforcement soil, etc., it is difficult to plant the plant, and by laying blocks on the front of the retaining wall and installing geogrids to prevent backfilling and backfilling at certain heights, it is insulated from the natural topography and the environment. There is a problem that is difficult to apply to the stability and soft ground.

In addition to the problems described above, in recent years, as part of a higher quality of life, there is an increasing demand for people to prefer natural and environmentally friendly structures with less artificial beauty, such as restoration of Cheonggyecheon.

Therefore, the present invention has been devised to solve the problems described above, by installing a vertical timber at a predetermined interval up to a certain height (about 3.0m), and then horizontally install a horizontal timber to support it horizontally To protect the slope and to stabilize the retaining wall, the timber nailing which is to be shot at regular intervals is installed in the back ground, so that the retaining wall is resisted by the friction force of the timber nailing to be fired against the force acting by earth pressure. The method of constructing the timber retaining wall in both ends using timber nailing, and in the case of the height above the timber retaining wall, the lower part of the vertical timber pile is placed in the ground, and the prestress cam beam is constructed by supporting the PS cable introduced with the prestress on the upper part. It is a structural system with both ends supported by a spring, which greatly improves its application height. The object of the present invention is to provide a wooden support wall for both ends and a construction method thereof.

Both ends support environmental wood retaining wall and its construction method according to the present invention for achieving the above object, if the soil wall height of the cut soil is less than a certain height, after installing the vertical timber at regular intervals, horizontally supporting it In order to protect the slope by installing wood horizontally and to stabilize the retaining wall, the timber nailing that is to be fired at regular intervals is installed in the back ground, so that the retaining wall can be fired against the friction force It is a method of constructing both retaining environment wood retaining walls using the soil timber nailing, which is made to resist.In case of more than a certain height, the lower part of the vertical timber is entered into the ground as required by the structural statement, and the cam beam horizontal wood is applied to the top. PS-K with prestress introduced when support or earth pressure is large To install the self-supporting wood retaining wall at both ends, i.e., the lower part is supported by the ground support elastic modulus boundary condition, and the upper part is connected to the rigid elastic modulus of the prestressed cam beam and the boundary condition where the prestressing force acts on the PS cable. It is a technique to equip.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.
