2. Description of the Related Art In order to protect slopes (slope) such as embankments and cuts from collapse due to earth pressure or seepage water, slender concrete blocks are arranged to divide the slope. They plant grass and stones in the area. Conventionally, when such a block is placed on a slope, a wire rope is slung on the block, and a hook of a suspension mechanism such as a crane is hung on the wire rope, or a U-shape is formed when the block is manufactured. Both ends of the bent rebar are embedded in the upper part and hardened to form a suspension ring, and a hook such as a crane is hung on the suspension ring to suspend the block above the installation position.

[0003] Since the bottom surface of the block suspended in this manner is hard to be parallel to the slope, when the suspension mechanism is lowered, the block lands on the slope with one side forming the bottom surface. The block is installed along the slope by tilting the opposing side of the block around the fulcrum and bringing the entire bottom surface into contact with the slope.

[0004]

However, among the above-mentioned conventional methods, the method of sling a wire rope,
It took time to attach and detach the wire rope, and it was difficult to move the elongated block stably in the air. Further, even with the method using the suspension ring, there is a problem in the safety of the moving operation of the block, such as the risk that the suspension ring may come off the block depending on the weight of the block.

[0005] In addition, the work of installing the blocks along the slopes as described above is complicated and dangerous. The present invention is intended to solve such a problem. The block can be easily attached and detached, the block can be suspended while being stably supported, and the bottom surface of the block is parallel to the set surface. An object of the present invention is to easily and safely perform the work of installing along a slope by suspending the suspension.

[0006]

In order to achieve the above object, the present invention provides two holding arms which sandwich a block on two opposite sides and intersect at an intermediate portion to pivotally support the block. inside the lower end of the clamping portion is lower than journalled position, the projection engages the recess provided in both side surfaces of said block provided with are opposed respectively, at above the pivotally supported position of both clamping arms By separately supporting the lower ends of the two links at the upper end of a certain link portion and further supporting the upper ends of the two links, each of these two links is linked to the link.
