In this case, when the spacing between H piles is relatively far apart, the brace and the brace are connected horizontally and are connected between the girdle and the girdle.

The support belt is maintained at a predetermined interval by the support, so that the earth wall withstands the earth pressure, and in this case, the connecting jack is connected between the belt and the support beam to closely contact the support wall installed in the direction of the earth wall. Is installed.

However, conventionally, H-beam is used as a brace, and when H-beam brace is connected, H-beam brace and base plate are welded, so when it is transported to the site, distortion of the base plate occurs, It is difficult to secure workers' safety, and there is a problem in that economic loss and construction delay are caused due to inconvenience of adjusting the length during recycling.

In addition, in the case of using the H-beam as the brace, the buckling occurs in the direction of the weak axis (YY) of the H-beam brace, there was an inconvenience that must be installed in the horizontal and vertical reinforcement to reinforce it.
Therefore, there is no difference in stiffness regardless of the direction, and use a steel pipe brace having excellent compressive rigidity, and a new connection structure for the steel pipe brace is required.
