SETTING METHOD FOR STRESS MEMBER

PURPOSE:To avoid the waste of H section steel when the levee crown of a landslide protection wall is lowered, by connecting H section steel units to each other removably via a joint member, and by releasing the connection after the steel units are erected in an excavated slot, to form a stress member for the landslide protection wall. CONSTITUTION:On the bottom web of a reference member 4 consisting of H section steel units, a joint member 5 is firmly fitted, and into a penetrating slot 3 set on the upper bed web of a stress member 2 consisting of the H section steel units, and a penetrating slot 7 set at the lower section of the joint member 5, a pin 8 is inserted, and on a notch at the tip of the pin 8, an engaging piece 10 is fitted. After the stress member 2 and the reference member 4 are suspended with a wire in a slot 16 formed by the excavator of an earth auger or the like, the operating wire 19 is pulled and the pin 8 is removed from and the connection is released. As a result, the only stress member 2 is left, and the reference member 4 is recovered and can be used for following erection, and when the levee crown of a landslide protection wall is lowered, then the H section steel units are not to be wasteful.
