To explain this in more detail, the block supporting tube is formed in a cross or square shape so as to support and protect the cross protection block formed in a cross shape or a rectangular shape, and at least one milk inlet is formed in the block support tube. It provides a support tube for the slope protection block formed to be able to inject milk of high strength cement therein; When the slope protection block is installed adjacently and continuously connected, the slope protection block is installed on the slope by inserting cross-shaped or rectangular block support tubes on the slope of each slope protection block, and each block installed on the bottom of each slope protection block. The support tube expands by injecting and inflating high-strength cement milk through the milk inlet, and the block support tube ensures that the lower side (bottom) closely adheres to the uneven slope, and the upper surface supports the slope reinforcement block that is supported by the slope protection block. It is to provide a slope reinforcement method to install.

Conventional slope protection blocks installed to protect slopes (slopes) are known to be manufactured using concrete (concrete mortar) and synthetic resins. No. 20-1986-2027 "Structural Reinforcement Construction Structure" and Utility Model Registration No. 20-271752 "Structural Reinforcement Construction Structure" and Utility Model Registration No. 20-408191 "Slope Stability Frame Assembly Block" As a rectangular block support tube, Korean Patent Registration No. 10-468035, "Retaining wall construction method using retaining wall precast concrete block and top-down method," has been proposed.
