Description

Lattice structures for slope stability

The present invention is a lattice structure for stabilization of slopes such as cut slopes. More specifically, the precast concrete member (horizontal frame) and the wooden member (vertical frame) are integrated into a lattice structure, and the inside of the lattice structure is filled with culture soil. It relates to a slope stable lattice structure that allows this growth.

However, on the slopes where concrete structures such as concrete retaining walls, anchors and shotcrete, nail nailing and lattice block method, stepped retaining wall and anchor method, and concrete blocks are installed, plants do not easily survive on the slopes, so the landscape does not match the surrounding natural environment. Therefore, it is necessary to develop new technologies that can harmonize with the damaged forest landscape or the surrounding natural ecosystem.

In order to solve this problem, recently, mortar is injected into two layers of fabric with high-strength geotextiles with aesthetics and scenery to form lattice columns. Although stabilization and greening are being pursued, problems such as high expenses are required and some parts are damaged after a period of time is exposed.

In addition, when trying to stabilize and green the slope using porous concrete blocks, there is a limit to the settling of plant roots because blocks with thick thickness and heavy weight are used to prevent the constructed blocks from collapsing. Therefore, the vegetation does not grow well, the transportation cost of the block is high, and the construction cost is high.

In addition, some attempts are being made to allow plants to settle through the spray-on grid structure method or the cast-in-place concrete grid structure method among the grid structure methods, but the difficulty of construction is high and the cost of construction increases. there was.
