Description

Soil Guard Structure and Establishment Method

The present invention relates to an earthquake structure and a method of installing the same, and more particularly, in a basement excavation work for various building constructions, the H-type steel provided with guide rails is placed in the ground, and disposed between the H-type steels. Install the steel plate on the ground to install the earthquake structure in the ground, connect the H-shaped steels to each other using cross beams, and then proceed with the basement dig construction so that the ground is stabilized. The present invention relates to an earthquake structure and a method of installing the same to prevent inflow of groundwater or groundwater.

In general, in order to build underground structures such as basement of the building or subway, the construction of a trench having a depth below the ground is carried out, and a protective wall is installed to prevent the soil wall from falling down due to earth pressure during the construction of the trench. In addition, the leveling work should be performed in parallel to prevent the groundwater from the ground flowing into the construction area.

Thus, as shown in Figs. 1 and 2 for the earthquake and the order, the trench is formed with a depth toward the bottom of the ground, and then the soil is prevented from entering the ground by ground pressure or groundwater at a predetermined interval. Arrange the shape steel 110 and insert the earth plate 130 made of wood between the H-shaped steels 110, and install the horizontal beam 170 aka cub in the horizontal direction so that the H-shaped steels are connected to each other After the structure was installed, a method of filling the soil in the back of the earthquake structure where the space was formed was mainly used to stabilize the ground.

However, such a method is a method of filling the soil on the back of the earth block structure formed of a hollow structure formed of the H-shaped steel 110 and the wood earth plate 130 in the state that the trench construction is in progress to some extent, It is easy to cause ground subsidence and ground collapse because the ground behind the earthquake structure is not stabilized, and the order function that prevents the inflow of groundwater is reduced as well as rigid by forming a barrier using a plurality of earth plate 130 made of wood. There was a problem of this lack. And it is difficult to recycle the earth plate 130 made of wood after construction, there was a problem that the environmental pollution occurs by embedding in the ground.

Therefore, in order to overcome such a problem, the earthen board is installed by inserting the earth plate made of wood between the H-shaped steels. By inserting the earth plate in duplicate, the rigidity is reinforced to some extent, but there is a problem in that the material cost and the amount of work are increased and the degree of function is still reduced. And the earth block structure was installed using a concrete earth plate made of high-strength concrete instead of a wood earth plate, but there is a problem in that the efficiency is lowered as the earth plates are made individually one by one because the gaps between the H-shaped steels are different from each other. .

In addition, there is a problem in that the construction cost is increased as well as the workability is lowered by the installation of the earthquake structure during the excavation work and the ground stabilization work behind the earthquake structure in parallel.

In addition, in installing the cross beams 170 connecting the H-shaped steels 110 to each other, by directly welding the cross-beams 170 to the H-shaped steels 110, there may be a problem in safety. The problem is that the installation and dismantling is possible only by welding technicians who are difficult to install and dismantle and which require high labor costs.

The present invention has been made in order to solve the above problems, the H-type steel combined with the guide angle is placed on the ground, and the metal plate is placed on the ground so as to be disposed between the H-type steel to install the earthquake structure in the ground After that, the basement is to provide a stabilization of the ground by proceeding the construction of the earthquake structure and the installation method of the earthquake structure to prevent the earth and ground or water flow into the workplace due to instability of the ground.

In addition, to facilitate the installation of the cross beams connecting the H-type steel with each other, thereby providing an earthquake structure that can be sufficiently installed and dismantled by skilled or non-skilled workers or general workers, and the installation method thereof.

In addition, by inserting a metal plate made of a single piece of steel between the H-shaped steel installed in the ground of the ground to install the earthen structure, as the rigidity is ensured, the safety is improved, and the work is simplified to shorten the air structure and the installation thereof To provide a way.

In addition, the present invention provides an earthquake structure and a method for installing the H-shaped steel that can be correctly inserted into the ground using a guide beam having a guide groove formed therein.
